Timeline video at 0-255 and export at 0-255

Hello...

My mind is already weak, I spent so much time and just do not understand what is happening.

My GoPro 8 shoots in the color range 0-255 in HEVC. When I import a video into a PrPro, the video becomes dim as I understand - program displays a range of 16-235.

Then I want to export the video to HEVC or 264. I also see visually and by metadata that the video is dim and is at 16-235.

I tried to export to DNxHR HQX 10-bit and received what I wanted the color is absolutely no different from the original, I checked all the light and dark areas - and it is, but now the file weighs a lot.

I just don’t understand what I need to do to get two things:
1) I want to work with video in the color range 0-255 during editing.
2) I want to export video in the color range 0-255 to HEVC or 264.

 

P.S. I read a lot of topics, I ask you do not need to talk about TV broadcast formats and old monitors. Just answer the question, is it possible in PrPro what I ask and how to achieve this? I just do not believe that this is impossible.

 

UPDATE:
The video card is configured as 0-255, win10, PrPro 14.0.3.

I admit that I understand absolutely nothing about this.

For example, here is a video https://drive.google.com/file/d/1aKM8kHm5wDd9_eXFq-aHe1HgCi2J88pA.

 

I play it in VLC, WMP or MPC and see more black and white areas. Metadata says the color range is full.

When I put a video in the PrPro I see that black turns gray. After export, I also see in the player that the color is strongly other after.

The full color range of 0-255 does not mean the number of colors 256 * 256 * 256 or 16 777 216? And limited color range 16-235 220 * 220 * 220 or 10 648 000?

 

What do you think what I can misunderstand?

What happens with video if it looks different in the PrPro and the same players after export?

 

And what should I do to make the video the same color after export in HEVC (not DNxHR HQX 10-bit) and in the PrPro?

Now it remains to find a solution for export in the range 0-255 in HEVC...

You've created the problem, actually. If you changed your card to the correct setting ... which is 16-235 ... then your problem would go away. You would still see black to white on your monitor.

 

GPUs and monitors work naturally ... more accurately ... at standard media settings. Video is 16-235. Period. Then the monitor displays it at full range black to white, and can sort out whether the media is 'standard' video media (16-235) or high-bit-depth/color-depth 4:4:4:4 media.

 

You do not have any media like that. It may sound odd, and well ... I did the same thing when I started out with video. And ... had to correct it to the actually normal and correct setting.

 

So I've been there, done that ... and fixed my mistake.

It is very rare for any Rec.709 media to be in 0-255 ... so I'm very doubtful that this is the case. I've not heard of anyone else saying this for GoPro media.

 

Full versus legal range has NOTHING to do with "old" or "new" video gear or styles ... but with the standards for video formats/codecs which have not changed. The only "0-255" formats I know of actually aren't ... because they're 10 or 12-bit formats in full-density color, which is 4:4:4:4 ... so they're 0-1023 (10 bit) or 0-4096 (12 bit).

 

I know of no 0-255 camera that works in "full" range.

 

I am a contributing author on a pro colorists teaching subscription website, MixingLight.com. The main "base" app there is Resolve, which has a ton of user-settable color management settings. What is the continual recommendation for setting your color management for all Rec.709 media?

 

Auto.

 

What's "auto" do in Resolve? Sets the display and output to 16-235 unless it detects "full" range media by the metadata in the media file ... and that really only happens with a few 4:4:4:4 formats/codecs. In other words, some of the big, spendy "pro" cameras.

 

Monitors automatically show 16-235 media from 0-255. It's the way the system works. Premiere is tightly hard-coded to respect and abide by all the proper international format/codec standards as applied in professional work.

 

What is your monitor setup? Is it calibrated and profiled with a puck/software combination like the i1 Pro? Are you perchance on a Mac, with a Retina monitor? The Mac/Retinca setup is unfortunately way out of bounds for displaying Rec.709 media, a very heavily discussed topic.

 

Period.

    Thanks for the answer.

    What do you think what I can misunderstand?

    What happens with video if it looks different in the PrPro and the same players after export?

     

    And what should I do to make the video the same color after export and in the PrPro?
