What is the best Bitrate for UHD 4K encoding in H264?

[Ann Bens]

Depends on the display device used.

Basically for a 52 Inch OLED Monitor or something of similar High End Picture quality. Is there a Bitrate where the image starts to degrade below? Or is there an upper limit where you get no additional Detail or resolution, but only bigger file sizes?

[Ann Bens]

No point in going higher with the bitrate then the original.
You need to do some trial and error.
If your bitrate is too high playback might fail.

Ok, I think this topic has gotten a bit side railed… probably because I didn’t word the question properly…

I shot footage on a Phantom 4 Pro Drone… in UHD 4K Resolution.

I brought this into Premiere Pro and would like to export the edited video in UHD 4K in the H.264 codec and mp4 container, without losing any resolution from the original encoding of the native footage. What bitrate would I select in order to achieve this? There must be a Bitrate threshold that gives you the maximum quality without just making the file sizes unnecessarily huge? yes/no?

You can only compare output datartar to input if the codec is the same.
But as pointed out by others bumping up the output data rate too high will produce a file that is difficult or impossible to playback.
Hence the questions on what device will playback the file and what are it’s technical limits.
That has to be the starting point.
If that device can cope with say 200mbps you then need to decide if that data rate is needed.
Do an enode at that data rate. Then try one 200mbps lower and compare quality. Repeat going ever lower. When you see a quality drop go back up one or 2 steps.

Thanks Ann I think that basically answers my question. I shot on a Phantom 4 Pro in 4K UHD. I checked the bitrate for recording and the specs on the drone camera says its recorded at 100mbps. So I can safely assume that increasing the Bitrate beyond that would produce no better quality. Thanks again.

*** I disagree. You haven’t yet clearly stated what you are going to DO with the file.
We don’t know its intended purpose…. which is a very important consideration. ***

you know David… I now remember the reason I stopped asking questions at Creative Cow… Because there’s never a SHORTAGE of SMUG & BUMPTIOUS characters like you who try to be vaguely confrontational with their responses, but only come off as IRRITATING. ????????

Thanks Pat, I think that answers it. I actually wanted to make sure I didn’t Lose any quality from the originally recorded footage on the output. I just checked and saw that the Original footage was encoded at H.264 100Mbps – so as you said, there’s no point exporting this higher than the original since there would be no additional quality gain. Cheers for your time.

“How is this file going to be played back?”

Why is that secret ? This is a very important question !

Its not a SECRET… I already said so above… Perhaps you should try READING the THREAD first without asking DUMB and POINTLESS QUESTIONS… ????
