the MOST IMPORTANT ATEM VIDEO you’ll watch… how to use ANY camera original in ATEM ISO re-edits!

Photo Moment - February 21, 2024

This is real. We've found a way to replace the 1080p ISO clips from ATEM Mini/Extreme Pro ISO's DaVinci Resolve project files with the camera original clips – from ANY camera. Don't use Blackmagic cameras? No problem. This is no longer a limitation. You can now re-edit your live shows at the highest quality and resolution that your cameras can record.

With the ATEM ISO models, you can record your live shows to an SSD, capturing not only the program, but also DaVinci Resolve project files and isolated video streams of each camera input for later re-editing. If you use Blackmagic cameras such as the Blackmagic Pocket Cinema Camera 4K or 6K, you can easily replace the ATEM-generated 1080p video files with camera-original 4K or 6K RAW files. This workflow is fantastic, but limited to Blackmagic cameras. Or at least, it was. Not anymore. Let me explain how…

Fellow YouTuber Alex Pettitt figured out the first part of this setup; he discovered how to convert the flat Resolve project file generated by the ATEM ISO into a true multicam project. This allows you to much more easily re-edit your live show, with actual multicam clips. This was a huge discovery; as far as anyone knows, he was the first to figure this out. I then realized that from there, it was relatively trivial to replace the 1080p low resolution ATEM-generated files with full resolution camera-originals, no matter what camera they came from. 

The Setup

As you’ll see in the video tutorial, I'm using a straightforward setup with the ATEM Mini Pro ISO and three cameras. This will work with any number of cameras that your ATEM supports. Do ensure that your ATEM settings and your camera settings are using the same frame-rate (i.e. 29.97 or 25). You'll need a clear cue, like a clicker sound, at the beginning of each shot for easy manual synchronization later (although after I made the video I realized that you may not need that — Resolve can sync these via waveform; more on that later). Start recording in the ATEM as usual, and also start recording in each camera, and produce your show like normal. After the live show, copy the ATEM files and camera original files to your computer, and begin this seemingly complicated, but actually quick and easy, process:

Convert to multicam

This first step is what Alex figured out; this is how to convert your “flat” multicam timeline into a true multicam project, where you can easily swap camera angles during the re-edit. It sounds tedious, but it really does go quickly once you have memorized the steps. 

1/ Open the ATEM-generated project file in Resolve.

Double-click the ATEM-generated project file or import it from inside Resolve. It will automatically adapt whatever your default project resolution settings are, but it’s also good to check that your project is set to the resolution of the camera original clips you’ll be working with later. In most cases, that’s going to be UHD (3840×2160). Even if you set this after you import the project, the change will ripple through where it matters.

2/ Color code the ATEM ISO camera clips.

Right click on each camera angle individually, and assign a color. I advise doing them in order of the color drop-down to make it easier to find them later; so CAM 1 becomes Orange, CAM 2 becomes Apricot, CAM 3 becomes Yellow, and so-on.

3/ Create a new multicam clip from the ATEM ISO video files.

Select all the video clips at once, and choose “Create New Multicam Clip Using Selected Clips”.

Set the Angle Sync to be based on timecode, and the Angle Name to be based on Camera name.

4/ Place the new multicam clip in a separate bin by itself.

Create a new bin, and name it  “multicam” so you can identify it later. This is extremely important, and important that the multicam clip is the only clip in the bin.

5/ On the original timeline, select the first color (Orange) clips.

Open the ATEM-generated timeline, and from the menu, choose “Timeline > Select Clips with Clip Color > Orange”.

6/ Disable “Conform Lock Enabled” on the selected clips.

Right click on any selected (Orange) clip in the timeline, and choose “Conform Lock Enabled” to disable it.

A red <!> warning symbol will appear on all the orange clips.

7/ Set the multicam clip to Camera 1.

Right-click on the multicam clip in the Media Pool, and choose “Switch Multicam Video Angle > Camera 1” (it should already be there). Verify that audio is also set to Camera 1; you won’t need to change that again.

8/ Reconform the timeline from the multicam bin. 

This is where the magic happens! Right-click on the timeline the Media Pool (the timeline icon; not in the open timeline itself), and choose “Timelines > Reconform from Bins”.

(1) Under “Attempt to reconform”, set it to “Selected Clips”. (2) Enable “set clips to Conform Lock Enabled after conform”. (3) Under “Choose Conform Bins”, deselect everything except your “Multicam” bin. (4) Finally, under Conform Options, only “Timecode: Source Timecode” should be enabled.

Click OK, and this will replace all the flat Camera 1 clip on the timeline with the multicam clip, set to Camera 1.

9/ Repeat for all remaining camera angles.

Do this again for each camera angle. Be sure to select the next color in line, and be sure to change the camera angle in the multicam clip to whichever camera angle you’re currently swapping out, before you conform.

Now, your timeline is a true multicam timeline. Every flat camera clip has been replaced by a multicam clip, already set to the correct camera angle!

Replace with Camera Originals

Now that you have a true multicam timeline, it’s time to replace the 1080p video files with your camera originals. While the following steps aren’t the only way to do this, I believe this is the safest way to do it, and ensures that even if somehow a clip gets out of sync, you can easily go back and verify it, as the ATEM-generated files are never deleted. 

1/ Create a Compound Clip for each camera angle in the Multicam clip.

Open the multicam clip again, so you see all camera angles stacked on top of each other. Select the first camera angle clip…

and choose the menu “Clip > New Compound Clip…”,

and name it something like “cam 1 comp”. Repeat for all camera angles.

2/ Import your camera original footage

Now it’s time to import your camera originals. If you have lots of angles you may want to name them now to make it easier to keep track as you go.

3/ Open each Compound Clip and align the camera-original with the ATEM-generated file

Right click on the first compound clip (“cam 1 comp”) and select “Open in Timeline”.

Drag the matching camera-original file on top of it, onto V2. You can manually align the clips visually or audibly (looking at the waveform), or what’s even easier (and which I discovered after making the video), is just select both clips, right-click, and choose “Auto Align Clips > Based on Waveform”. Resolve will analyze the audio waveform of each clip, and move the new clip on V2 to align with the original on V1.

Note that the clip on V1 (the ATEM video clip) must not move. It will be lined up at the start of the Compound clip and needs to stay there.

4/ Repeat this for the other camera angles

Repeat this process for each additional composite that you made!

Now you’re done! You now have a full resolution version of your live show, at the highest quality that your cameras can generate. 

A Note About Cameras with Varying HDMI Delay

One amazing advantage of this process is that you can now compensate for cameras with varying HDMI delays. If you’re using all the same cameras, then this doesn’t matter. But if you aren’t, then this might. All HDMI cameras have a slight delay between realtime and what comes out the HDMI port. Some cameras have very little (as little as a single frame), most have between three and seven frames delay, and some like GoPro cameras may have well over ten frames delay. Wireless cameras could easily have half a second delay, depending on the wireless HDMI technology you’re using. For a live production, there’s nothing you can do about it. But now, in the re-edit, you can compensate for that delay. If you have something visual to align to at the beginning of the show (such as a timecode display), then you can offset the most-delayed cameras to bring them in sync with the least-delayed cameras. By slipping the camera-original in the compound clip, you can move it so it’s in sync with the other cameras instead of with the ATEM recording, making everything line up perfectly. That’s pretty amazing. 


This workflow offers unparalleled flexibility, allowing you to match camera original files from any camera to your ATEM-generated Resolve project file. Whether you're using Blackmagic cameras or not, this opens up new possibilities for your production workflow.

Conveniently I saw Alex’s video this morning which helped me follow through with an ISO file we just recorded. Note I can appear really smart with my colleagues even though you two did all the heavy lifting. Thank you!!
Haha happy to help make you look awesome 🤩
It if you record log on cameras won’t it show up in log form on the atem mini pro iso? How do I make it log on the camera but have a “normal” 1080p image on the atem?
On the LUMIX cameras, you can choose for the LCD and/or the HDMI out to have a LUT applied so it looks “normal”, but the recording will be Log. I don’t know what other manufacturers cameras can or can’t do.
This is wonderful! I was worried about not getting 4k especially when I want to zoom in on a shot. This work around is awesome! Thank you!!
Ok, I followed this and it worked for half my show. I stopped the cameras in the middle for about 10 min and then started again. I see all my cuts but when I try to reconfirm from bins it isn’t doing anything to the clips that are in the 2nd half. What am I missing?
@photojoseph  thanks so much for the help. I'm not sure why they won't sync automatically but I just did it manually. They are all black magic cameras so I'm not sure what the issue is. Time code helped.
That’s not going to work for the conform. You had that checkbox “place clips from same cameras on one track” (something like that; I’m not looking at Resolve now) enabled? It must have put them somewhere or it would give you an error. You could manually place them and do the math for the distance between clips (when cameras were off) but that should not be necessary.
@@photojosephit appears to only add the 1st group of clips even though I selected all. I tried just selecting the 2nd half clips and that worked. So now I have 1 multicam clip for the 1st half and another one for the 2nd. Do I have to edit them separately and then stick them together?
Ok! When you made the multicam, did you select all the clips, and enabled the option to put clips from the same camera on one track? Did you open the multicam and verify that all the clips were there, with a 10 minute gap where the camera wasn’t rolling?
can you talk about your atem case setup? Thanks for this video!
Very nice. This also means that after this you can color correct the multicam clip, which in a lot of situations is much faster. It would still be better of course that BM changes the firmware that this is the default behaviour of an ISO recording project.
Yes exactly. As for BMD changing it; I wonder if this is why they haven’t. Prior to this the only workflow was buying their cameras.
@photojoseph AMAZING!! But I’m distracted. I need to know what is that light behind you and possibly a link! Haha Thanks!! 😂😂
Haha you’re not the first! I bought it at a store in Slovenia called Mömax but I’ve seen similar designs at other shops too.
Thanks for the video.
Has probado el Osee GoStream Deck?
Aha, gracias. This video will be on the Spanish channel soon! I haven’t used the GoStrean before. It does look very interesting but without ISO recording (which no other switchers have), it’s not as interesting to me. Thank you for following both channels!
@@photojoseph No, thank you for your kind reply. I'm not promoting anything. I was just wondering if you had approved it? I am your follower on your channel in Spanish. but I see that you upload more videos here. Regarding the product. I only see reviews in English. I understand English very little. and what I have seen seems to be a better product in some points than the atem. I have the extreme atem, I love it. an abarazi, greetings from Ecuador
I assume you’re just here to promote another product since that switcher doesn’t offer an ISO record function which is what this video is about. I’m sure the GoStream is a nice product, but without ISO recording, in context of discussion on this video, the Osee scores a 0/10.
@@photojoseph option to Atem 😬
Nope. What’s that?
Do you know if you record with the Atomos Sumo19SE, that it creates a multicam clip straight away to use in Resolve? I saw your other video on the Shogun 7 from 3 years ago, and in Final cut it's an instant multicam. Either way, I guess this workaround should also work with the Sumo19se?
Oh I see. No modifications. Nothing hidden in that video!
@@photojoseph You misinterpreted me I think, in your own video with the Shogun 7 it looks like there is an instant multicamclip in FCPX straight from the XML file. That's why I was wondering if that was correct, or whether you did it personally in post, but didn't put it in the video. Either way, still amazing that you and Alex found this workaround!
I did not know that the sumo did that. But yes, the same theory would apply. Very interesting indeed.
seriously amazing. isn't it crazy this has been possible all along? just took brilliant minds to figure out this loophole. great work Joseph! using this tip on a project now and thrilled!
Nice to see you here buddy! Yeah, this is pretty awesome. Now to figure out where else to apply this ancient and awesome technology :-)
Im a complete beginner, so I might be missing something. Don't I have to delete the original A/V track in the compound clip I created to ensure I get the 4K out? Or am i just relying on that the top track is rendered first? Would there be any repercussions to deleting the old ATEM 1080P track?
@@photojoseph Thats amazing, thanks for the hard work and sharing this with us. I've been recording in-camera 4K, and manually replacing, syncing and editing it before render.. This will make a big difference for me. Cheers
Only the top layer of video is visible. All audio would be audible so you’d need to mute the original audio track; I neglected to show that but that will be figured out quickly. The only reason to retain the original video is to have a known sync track, but yes once everything is in place it’s safe to delete.
This video is amazing! I started fiddling with Multicam Recently, but now being able to do all this with 4K to match the ISOs from the ATEM is just lovely.
I'll need to figure out the camera part though, cause my camcorder doesn't allow me to record 4K while sharing content to the ATEM.
Nice! And yes some cameras can only record HD while outputting over HDMI. Sounds like you’ll need a new camera.
DOOOOPE! I was really thinking on how to do this months ago! This video save my life haha! Thanks Joseph and Alex, I'm following your wotk since 2020 with the atems keep going. Cheers from Costa Rica
excellent tutorial! why doesn't this dude have 100k subs for all his excellent and hard work?
Thank you, I appreciate that! Hopefully one closer to 100k with you 🥹
Hi Joseph!

It was very nice to meet you in Budapest today!
I’m glad you said hello! This is such a beautiful city. We’re really enjoying it.
Been dying for a 4K solution forever on this without buying BMCC, and you've totally made my night. Well worth the little bit of work. Can't wait to try this.
What case are yu using for the atem switcher and monitor? or is that a custom case
This is great. A lot cheaper than Tentacle Sync, although a pretty complex procedure. I'm grateful you made this comprehensive tutorial. I'm adding it to my bag of tricks. The WWII clicker is great. I can think of many applications for that. One thing about it is that it's not as alarming to actors/talent as a slate. I'll be sure to save this and Alex's video for future recall. Thank you!
Honestly the process is simple once you get the hang of it, and it can be done in just a couple of minutes.

Would you tell me more about the background light that you are using?
@budokahn thanks!
Thank you They look great and it was an excellent video! @@photojoseph
Bought on sale st Mömax in Slovenia for €99
Thank you so much for the video! Can you please give me info on the green case build at 3:54?
Thanks bud. @@photojoseph
Thank you! and Thank you!
You are so welcome!
This is exactly what I have been looking for!
Can you tell me where to get the light you have behind you? I see Allie of them on their channels i can’t find it
It’s from Mömax in Slovenia although I’ve seen similar lamps in many stores.
dope. thanks
You bet
Cool! Did you also manage to find a solution for the Supersource, DSK and USK. Don't appear in the timeline?
If it appears on the timeline, it works. Standard PiP shows up (USK, if memory serves). Pretty sure supersource doesn’t but I haven’t looked at that in ages.
Could this multicam clip be used to color correct the cameras original clip? This is a technique (correcting the master clips and creating a good start poin t for different camera shots). I've used in FCP and its a main hesitation I've had in the Resolve multicam. I have seen ways to enter the color mods on the color coded and selected clips, But being able to modify the master clip is what I've been looking for. Great technique you outline that might let me move away from FCP Multicam clips. Thanks for the billiance here.
I’m not totally sure I follow. But let me see if I do. To grade a Resolve multi cam project, you can either grade each cut one by one, or open the multicam clip and grade each angle once. Either way works. And you can do both; do a base grade inside the multicam then finesse each cut (or just the ones that need it) on the timeline. Is that what you’re asking?
this opens up a LOT of possibilites. I can carry 4 sony cameras and lenses in the space it takes 2 BMPCC and lenses. important considering I never check bags.
That’s awesome
a small tip regarding sub-frame audio aligning: you CAN do that! make sure, you trim off a little footage in front and at the end, then you can nudge fine-grained with ALT-LEFT and ALT-RIGHT cursor key, but you have to cut front & back, so you have wiggle room! Also use the menu: Trim->Slip Audio
Haha yeah, but also videos get too long and people who don’t want the extra time out. It’s a tough balance.
@@photojosephgot it :) too nerdy stuff going on :) but who's talking ATEM, Blackmagic and Multicam is already deep sh#$ into nerdy stuff :) :)
@@dr.outdoor aha, gotcha. Yep, totally fair. I actually originally scripted an explanation of why the audio and video won’t line up properly unless you’re shootings with genlocked cameras but nixed it because I felt it was too esoteric for this video. Those who already know that will know that’s how to get perfect alignment; those who don’t won’t likely care or at least not want the lecture in this video. It’s my biggest struggle in making videos like these; deciding what to leave out!!
@@photojoseph that's absolutely true... still, since you are working in a multicam clip with more other "new" 4k clips, you will have to align audio in a later stage to the new videoS, and here, the ALT-LEFT/RIGHT might come in handy again...
But wouldn’t that just slip the audio, potentially putting it out of sync with the video? I’d prefer that the new audio stay aligned with the new video, since the new audio is what will get used.
Does this work for 2h+ productions? Or will the drift make it unfeasible for anything longer than a few minutes?
As long as you’re in the same frame rate there should be no drift. But if there were, you could compensate with a few slice and nudges inside the multicam clip.
Did you disable the the other audio tracks. I know if I don't do that, the AUDIO is sometimes over modulated as having multi clips with the same audio it gets really Loud or the is a slight offset and you hear it..
I did not talk about audio (I should have) but yes 100% you want to disable the original audio track. As mentioned at the end, you could even bring in high quality audio via an 32-bit float recorder if you really wanted to get the best of the best.
BlackMagic seems a little greedy and selfish keeping the knowledge away from People. Thank you for sharing. 🤨🥲🥲
So I do not have the ISO version but I was wondering if you would know why I get a little bit of a buffering effect when I run my r6 4k 24fps. for the most part its all good but at some points it looks like its buffering, laggy for a sec. If anyone could answer this.
@@photojoseph I appreciate the reply’s! It was set on 1080 24. But I changed it to 23.98 to see if that matters.
That’s probably the issues
@@photojoseph this is happening when I am recording to an ssd but it even happens when I am not recording or going live. Just looking at the previews it will do this weird buffering thing.. It’s very hard to explain with out seeing it. I was not aware that you can change frame rates in your atem board. I will look into that.
Is the ATEM set to 24p? While it can convert frame rates it’s best to feed it the native signal frequency. If you’re talking about buffering while streaming then that’s an internet problem.
I wonder how long it will take, until Blackmagic will directly prepare a multicam clip from within the ATEM project... at least I hope so!
Outstanding. I'm also impressed with YouTube recommending this exactly as I am working on a project like this! Sometimes the universe delivers. Thanks @photojoseph!
Haha that’s fantastic!
Imagine it being 50 years since Timecode was created and we still had to clap and do stupid things to sync audio and video or multiple video clips because it wasn’t standard yet on every camera and audio interface. Oh wait…..
Well, the cameras do have to have the SAME timecode to be of any use.
Thank you.
You're welcome!
You're right - it wasn't clickbait - well done, guys. This indeed is massive for the ATEM Mini range - I have an old project I can try this out on straightaway and had given up using BM cameras anyway.
Amazing video. What do you use to zoom in and out when are screen recording.also I record my audio from my rodecaster pro bc the audio isn’t great coming from the atem. Do you know of an easy way to swap out audio I normally have to go through a whole process. I also want to be able to edit multi cam on the edit tab but I know that’s not possible as far as I know.
1. Screenflow
2. Swap out audio the same way I swapped out video here. Just record the entire show and line it up with the ATEM audio track.
3. What I showed here is the edit page. Do you mean the Cut page? I never touch it; don’t know.
This is great! Not only opens up using different cameras but also wireless camera angles and SDI feeds as well.
BOOM...that is it. When Alex released his video a few days ago, I asked for the possibility of this process in my comment....while I have been thinking it may not be possible eventually... you took the baton and finished it off.💥💥💥 Thanks to you and Alex
Haha thanks man!
Why not using the auto align clips by audio option ?
See my pinned comment 😳
I totally concur
You dont even need to connect the cameras to atem, only the microphone 😊 you can have wireless atem setup but you will have to switch without seeing what goes on in a way

Ive tried this before but I had it more complicated, I was replacing iso files and had to align the timecodes on them and that really was a lot of work

Thank you so much ❤
@SlimboCanavi interesting. You’re the second person to talk about switching a show but not live streaming it, and not even connecting the cameras. Fascinating!
Genius idea. If you use lumix box cameras, you could monitor all of the cameras over wifi in lumix tether as you switch with the atem.
Maybe record a tentacle sync into the mic 1 so the ISO just records black files with camera timecode burnt in.
You'd have to set up a black multicam project like in this video and then finally swap out the files via the audio timecode.
I avoided doing many live shows for this reason - I didn't want to invest in wireless transmitters or lay long cables.
This is perfect! Thanks again for the idea
Interesting approach!
Does the multicam clip work on the cut page? I've grown to love the speed editor and would hate to sacrifice the sync bin feature if the multicam clip doesn't work with the multicam buttons on the speed editor on the cut page.
No. The original non-multicam timeline is designed for the cut page. I am pretty sure proper multi cam clips don’t work in the cut page. I could be wrong though; in not a fan of the cut page.
I will not use it, but I watched whole video because I like smart ideas ;) THX
@@photojoseph I can't because I have Mini Pro, not ISO. ;)
😅 I appreciate that!
If you're using blackmagic cameras, replacing clips is not so difficult, you can just replace ISO files with original raw files from cameras as they are already perfectly synced, but this is a real game changer for everyone not using bm cameras with atem. And of course, the fact that you can have multicam sequence instead of the original atem timeline is priceless. Thank you guys for doing this! 🎉❤
Actually, if you have BMD cameras, all you have to do is put the RAW files in the folder and Resolve finds them, and treats the RAW as originals and the 1080p as proxies. But of course you can regenerate proxy files once you build these new sequences if you need them. Yeah this is super cool for sure! So glad Alex figured out the first half.
Thank you for improving the process from Alex to the next step. This improves the workflow and also the results so much.
