Great video and really interesting analysis! I've been considering a GH 5 myself as I would like to do more video, already have a GX 8 and love it, most of the photos from my site are taken on the GX 8 - - and I just think it's a superb system!
@PhotoJoseph Hello, while recording content for my YouTube channel I have not been happy with the video quality using a good quality Logitech webcam. Most of the content I plan to record will be closeup instructional work on my workbench. Trying to keep the total cost below $1,500, is there a camera body and lens you would recommend? Thanks - Dave
PhotoJoseph Record and edit the video later. (Thank you for your reply) - Dave
Thanks for bringing up my question on your show!
1. I'm not saying they should remove their 3D face unlock, it's a cool thing to have. But it's wrong that they force you to use only 3D face unlock to unlock the phone. It would have been easy for them to put a fingerprint reader on the back also, like 100s different Android phones have. This means if you for any reason (driving, cooking, whatever) if you cannot or you don't want to touch the fingerprint reader on the back of the phone you can still use face unlock. By the way Android phones have had face unlock since 2011, sure not as "reliable" as the 3D face unlock, but still it's been available in Android since 2011.
2. Many case designs have right now a hole on the back only to show off the Apple logo. The hole on the back of cases should simply be to use the fingerprint reader instead of showing the Apple logo. Or they could have formed the fingerprint reader into the shape of the Apple in the Apple logo that would have been even better in terms of engraining the Apple logo into their customers minds by having them touch the Apple logo 50 times a day when unlocking their phone.
3. Fingerprint reader is plenty secure enough, you're not going to ask 50 thousand+ people to put their finger on the back of a phone to hack into it. You're never going to randomly bump into a thief who steals your phone and happens to be 1 out of the 50 thousand that have the same fingerprint as you that can unlock your phone. That statistic is meaningless. What's much more likely to be a huge issue is for families that have identical twins, they can face unlock eachothers iphone X easily but identical twins do not have matching fingerprints so the fingerprint reader is the only way to make a phone usable in a family that has identical twins which affect many. Sure fingerprint readers can be tricked, but that's most often not an issue when it comes to securing your phone. If you're a secret agent carrying state secrets in your phone you can use other more intricate ways to secure and encrypt your phone. But for normal people the fingerprint authentication is plenty secure enough.
4. if the 3D face ID is opened up to third parties, then how can Apple at the same time suggest that for security the 3D face ID information never will leave the phone? It's either one or the other.
5. Google's Project Tango such as implemented in the Lenovo Phab 2 Pro is the better way to have instant 3D scanning of objects, places etc, it's got to be on the back of the phone, not on the front of the phone. Otherwise how do you hold it and be able to see what you scan into the 3D world with third party apps support etc? Now I'm not saying it's not cool to have selfie 3D scan, that's cool too, but the better place to have 3D scanning tech is on the front side of the phone. Yet another reason it's quite wrong of Apple to not use all that space that is on the back of the phone, it would have been easy for Apple to put IR blaster + IR camera type 3D scan tech on the back of the phone too.
6. You would not need to flip the phone to unlock it! I'm sure the 3D face unlock works just fine with those sensors at the bottom too. And you could also take selfies with the camera at the bottom if you don't mind it being at the bottom. But it's only for selfies if you want to have the camera at the top then you simply flip the phone, only for when you take a selfie. That's the only way to do a proper bezel-less phone. (Sure, by bezel less I mean 1 bezel still at the bottom). Condemning the design of the top of the phone (the most important part of the design of the phone is at the top) with these horrible cut-out ears at the top of the display just for people to not have to flip it when taking selfies, that's just wrong. Normal healthy people don't need to be taking selfies every 5 minutes neither. You take a selfie possibly once a week in average, if you live with a normal level of narcissism. But if you're a selfie-addict taking selfies every 5 minutes, then you can simply decide to use the phone flipped with the selfie bezel at the top most of the time. There's no reason the whole of iOS can't be made to work just fine when the phone is flipped.
1. It's a waste of space to have all that empty unused space on the back of the phone. Adding a fingerprint reader does not take up any more space and barely if any weight, might even cut down the weight and size slightly by them removing a round part of the back glass cover.
2. You need to try phones like Huawei Mate 7/8/9/10, LG V30/G6, those backside fingerprint readers are fantastic for usability, there is nothing better. It's the natural way to grab a phone. The front-side fingerprint reader has been the most awkward place to have the fingerprint reader.
3. There's lots of different levels of fingerprint security. The newest fingerprint readers use ultrasonic fingerprint scanner technology to create a detailed map of the minute details of the fingerprint and detect liveness, engineered to make user’s authentication extremely difficult to imitate. And if some people are paranoid about security for their data, they should be allowed to use FaceID or even better an iris scanner for authentication each time if they prefer. But for 99% of people for 99% of the time, the fingerprint reader will be just fine.
If all that third party apps can do is use Apple's Funny masks API, then that means the technology is pretty much useless. The obvious thing people would want is to enable detailed 3D face scanning to any third party application, for apps like 3D realistic capture/rendering/animation type apps, but since Apple has chosen to make FaceID the way to authenticate the phone and since Apple has promised that the detailed face scan will never leave the phone, this makes all these third party apps impossible to make. There might be some funny animated face motion apps API and that's about it.
The problem with facial recognition is when it stops working!
Found this video about the new GH5 update. In it they discuss how they tried using a Lexar x1000 card and it was not fast enough to do c4k 24p. They had success using the v90 card from Panasonic. The relevant bit starts at 3:20
I agree PATREON is another major chore with little or no reward. ☹

My tough question: Do you still remember you wanted to do a show with Vidiu and Live:Air?
Wait, apple does not have a trusted devices setting? So when you are in your car and your phone is connected to your cars bluetooth, no fingerprint is needed? Or when it is near your apple watch, etc? Wow... I still am very curious as to whether you can take a profile photo from say FB and map it to a 3D model and unlock the phone. I am sure it will not be long before someone figures that out..of course only after 10 billion units are sold. Honestly, why don't they just build the reader into the power/sleep button? Or on the phones edge, you know where your fingers are ALL THE TIME. Or figure out an overlay for the bezel-less screen.. I am sure there is a clear sensor tech just waiting to be dev'd or already out there.
Actually, I am super familiar with facial, in fact whole body recognition as I use the Xbox Kinect system for 3D Scanning. The trusted device system works. Someone would have to steal your phone, stand next to you, and open it. Not a likely scenario. But, with that said that can be bypassed as well. As far as codes go, I have never trusted them and would NEVER open my phone in view of anyone to compromise that. The fact is... you can try, but you will never fix stupid. FR may help a lot of folks, and I hope it does.. but the truth is..and you can take it from someone who knows...if I want into your phone...I can get into your phone, no matter what Apple sells you.
Thank you for the MEVO info and thank you for the split screen info. You are right, it is not an easy setup. Darn!
I have WIRECAST 8, i was hoping that would really bring all this together. It is great.
What are your thoughts on it, do you have this?
PS. I heard you said that MAC webcam suck, thats terrible to hear. I use my MACBOOK PRO, IPADPRO and IPHONE 5S for all my work.I love MAC and surprised to hear this. makes no sense by them. Arg!
Keep up the great work!

WIRECAST just upgraded to WIRECAST 8. It was already basically $1000.00. This upgrade is now, which has finally caught up with FB, coming at a cost. Anywhere from $2-400 or more bucks. Thats ridiculous. I will not be upgrading

@photojoseph Agreed!
