And right there is where my knowledge and understanding are insufficient for me to agree or disagree. The sizes of the 4K files are the same, regardless of whether I record in 4K/30 or 4K/60. Either way I get 5 minutes 27 seconds of footage for each 4GB "package", but I have no problem viewing the 4K/30 files straight from the micro-SD. So, you're right, I think, maybe, but I don't grasp why.
Latest Firmware Update for P4P - Apr 12

When something already works, don't update. I'm still on my original firmware and Go4 4.0.2
It's possible that 4K/60 is getting extra compressed down to the same bitrate at 4K/30 because of bandwidth or other hardware limitations. That would be terrible if true.
Let's assume that IS true. My question is, who are you blaming for things being "terrible"? DJI?, or your computer's hardware?
DJI of course, if they've made hardware that can't handle what the camera can shoot. What's the point of 4K/60 if you're compromising quality over 4K/30 because the drone can't handle the bitrate?
What you're saying doesn't make sense to me, then. You're saying that it's DJI's fault that my computer's graphics card isn't capable of handling the file.
Yeah, but there's no truth to that. I've already demonstrated that 4K/60 footage from the P4P can be properly displayed.
Interestingly, I've also just discovered that after rendering in my video editor, with a 2:50 video still being 1.17GB in size, the file can be properly displayed if I use QuickTime to display the MP4 file. None of my other video players will display the file properly.
My PC have a hard time playing up the raw 4K60fps videos from the P4P.. Im running a fairly competent pc, i5 4690K overclocked to 4.5 GHz.. But i have no disillusion that the videos are stutterless on other computers since the video i take looks great on youtube(compressed video).
So before anyone blames the P4P, check your computer first.
No one is talking about displaying the footage. We're talking about bitrate and data differences between 4K/60 and 4K/30. If the bitrate is the same, then the extra frames of 4K/60 are resulting in significantly more data compression over 4K/30 and therefore producing significantly lower quality video.
I'd consider 60fps worthless if it results in drastically lowered image quality. One would except a system that's advertised to shoot 4K/60 to not do so by compromising quality over 4K/30.
Obviously it will be lower for anyone with a thinking brain.... But certainly it is not drastically..
As far as I'm concerned, that's moving the goalposts, ie, changing the subject. I never made any claim that the video quality of 4K/60 from the P4P is equal to or better than the video quality of 4K/30. The intent of my comments has ALWAYS been to demonstrate that claims which say that the P4P cannot properly produce 4K/60 footage are false claims. It is a PROVABLE fact that each frame contains less information in 4K/60 than it does in 4K/30.
The 4K/60 issues were acknowledged by DJI and corrected in a very recent firmware update. The issue I'm addressing is your claim that a 5 minute and 27 second clip is the same file size whether shot in 4K/60 or 4K/30. If true, that's absolutely ridiculous and unacceptable on DJI's part.
Well, it's actually a fact rather than a claim. Please expound on why you find it ridiculous and unacceptable. To me, it's just the way it is.

It's been chatted about at length. 4K 60p involves 'pixel binning' to make up the 60p. It's not really 60p. Forget it. Use 4k 30p.
Chances are - and this is pure speculation on my part, but it's possible that because it's not really 60p your computer is trying to in fill the missing data causing it to crawl.
None of the files the p4p produce are editing software friendly.
Have you tried encoding the footage as prores? You might find that helps.
However it's a fact that there is NO real benefit to shooting 60p at 4k. The high bitrate and 60fps is not happening. It can't squash that info into that file size. 30p yes.

Agreed: that 4K/30 is sensible, while anything else is not (except for 4K/<30K, for which I have no reasonable use.) Agreed that 4K/60 is not sensible. I was simply demonstrating that 4K/60 is POSSIBLE, since it seems to me that there are a great number of Phantom photopilots trying to claim that it is NOT possible.
ProRes? No thanks. I've paid for Cyberlink PowerDirector 15 and I'm not willing to pay more for something else.
In the future, I may become willing to pay for ProRes or... what's the other expensive one from Adobe?... but at this point I'm not.

Thanks very much. I'm subscribed to Frederick's channel but hadn't yet seen that video. He's a member of this forum, incidentally.
When using an Android device, "Normal" still has the old and poorly chosen name "None", and there is no "Art" profile. Other than those exceptions, the profiles are the same as what is shown on that video.
