Hi There newbie to PRO X 13, coming over to from Resolve and years ago Vegas.
Has anybody been able to configure PRO X to make YouTube accept the HEVC mp4 as a HDR file.
Input files are in flog 10 bit
Movie setup to BT.2020
Output set up to BT.2020 10bit.
Can't find a good description for HDR other that it should be possible. What setting am I missing?
Hi and welcome to the user to user forums.
Looks fine so far but what are the settings in the export advanced section look like? (first image)
Have you looked up the YouTube upload requirements? Also the acceptable file types?
Then check the bit rates set in the program.
Are you a new YouTuber?
If so there are upload time limits to adhere to for a while.

I raised the bitrate to YouTubes recommendations, but it did not change anything. There are some metadata that needs to be set for HDR, but can't really figure out how to verify it. I will keep searching. I just prompted the forums to see if anybody had a workflow that I could copy. Thanks for the suggestions. Will post my settings if I get it to work.

Hi Morten,
From all off my tests, VPX13 does not support export in HEVC / HDR
Just import is supported for UHD / HEVC / BT2020 / HDR / 4.2.0 / 10 bits
If you export in UHD / HEVC / BT2020 / 4.2.0 / 10 bits, lot off metadata are missing as:
Color primaries : BT.2020
Transfer characteristics : PQ
Matrix coefficients : BT.2020 non-constant
Mastering display color primaries : Display P3
Mastering display luminance : min: 0.0050 cd/m2, max: 1000 cd/m2
Add: no HDR, PQ or HLG option found in encoder settings.
Regards.
DéDé.
Hi Morten
As DéDé, @sasiuk, has commented HEVC HDR video is not supported by VPX 13 or Youtube which does, according to YT's supported formats list, support standard HEVC which VPX 13 can export.
However although you may get a HEVC video to upload, do be aware that it will be converted to various formats - h.264 being the most popular - in various resolutions as low as 240p to cater for different viewers Internet connection speeds and browser capabilities.

Thanks for all Your input, happy to see that there is a such a helpful and well informed community around VPX.
I can confirm that the VPX HEVC output BT.2020 10bit uploads to YouTube just fine, and the grade made in VPX also looks as expected.
It was my oversight that YouTube actually did not support HEVC HDR but only H.264 HDR. So guess I will try some ffmpeg magic to get that HDR icon to light up. But that is outside the scope of this forum, so thanks.
Just trying to see how far I can push the quality of my log footage.
Reason for getting the VPX license, is that I start regularly to hit the limits of the free version of Resolve and with the non-profit occasionally video work I do (shooting mostly stills), it simply cannot warrant a full Resolve license. And as I got a previous Sony license, I was able to upgrade to VPX. (Made one, error though, upgraded to a studio license first, just to figure out that most of the features I would like to have where actually in VPX).
Did not take me to long to get the bearings around VPX, seem pretty straight forward. Resolve is sometimes to much of a good thing, (requiring to much time to watch endless tutorials), so the idea was also the get a more simple tool, as my workflow with a single mirrorless cam is shoot -> cut, correct, grade -> render.
The more advanced design stuff I do in Affinity Designer/Photo and the animation in Blender and mix it up in the NLE.

Hi Morten and welcome to the community,
I am curious to know if Affinity works as an external image editor with VPX. Did you try changing the external image editor in Program Settings, Folders to Affinity? Does it work?
I use PaintShop Pro and I alternate between it and Xara Designer Pro X. If I use Xara, I have PaintShop Pro as the bitmap editor for Xara, so I can get the best of both worlds.

Yes I was able to setup Affinity Photo as an external editor. If I right click on an image object in the timeline, select open in external editor. Affinity Photo is started and loads the image.
But edits to the image is not reflected in VPX, until the project is reloaded. Seems the image file is cached in VPX.

Hi,
Thanks for confirming.
Try clearing the cache - Edit, Empty undo and cache memory.
Then hit play or something and the photo should update.

Hi all,
My yesterday message
From all off my tests, VPX13 does not support export in HEVC / HDR
Just import is supported for UHD / HEVC / BT2020 / HDR / 4.2.0 / 10 bits

Color primaries : BT.2020
Transfer characteristics : PQ
Matrix coefficients : BT.2020 non-constant
.....
Solution found on German langage forum.
Export in HEVC / HDR works fine under VPX13 IF hardware acceleration is disable.
Encoding should be switched on CPU, but rendering time is long, long, long
As Transfert characteristics PQ (Perceptual Quantization) and BT2020 color space are present in Metadatas, exported file read on my 4K HDR TV is perfect and switch to the right color space.

This was a tough one to fix. Took me some days to and from to get it right (almost gave up). Reading the descriptions over and over, and reading all the few resources available. Most of them described the workflow for the so called "Supported apps" (All the video edit big boys), not so much how You could do it without the direct support.
I tried many different combinations again, again and again. But the recipe below worked for me.
I used the GPU rendering HEVC Rec. 2020 10 bit, and yes it do not add the right metadata, as stated by DéDé, but that is fixed by the next step.
The official google doc that can be googled :-) states that You should use some kind of metadata program called MKVMERGE to end up with a .mkv file with the meta data that You can upload to YouTube. I could not get that to work. I tried using ffmpeg to transcode to some of the supported codecs VP9 (took ages) MP4 combined with MKVMERGE but to no avail.
Today I stubbled by a blog (https://www.adsplch.com/posts/ffmpeg-hevc-metadata/) saying that the metadata could be added to a HEVC file using ffmpeg. And the blog had a a reference to the ffmpeg docs https://ffmpeg.org/ffmpeg-bitstream-filters.html and https://ffmpeg.org/ffmpeg-bitstream-filters.html#hevc_005fmetadata. Adding meta data do not reencode the file, so it is way faster than transcoding to other formats.
The syntax for the parameters is a bit complex: (all ffmpeg parameters are)
ffmpeg -i WhiteChristmas.MP4 -c copy -bsf:v hevc_metadata=colour_primaries=9:transfer_characteristics=18:matrix_coefficients=9 WhiteChristmas_meta.MP4
But it makes very much sense, when You read the other documentation for YouTube HDR
colour_primaries=9 (bt2020)
transfer_characteristics=18 (arib-std-b67) HLG
matrix_coefficients=9 (Rec. ITU-R BT.2020-2 non-constant luminance system or bt2020nc)
The extremely interesting thing here is, that even that the official documentation from YouTube do not mention HEVC HDR as supported, it actually works to upload the output file WhiteChristmas_meta.mp4. (I also tried to transcode HEVC to H.264, is also works, but does not seem to be necessary).
When I first tried to upload the file WhiteChristmas_meta.mp4, I was disappointed, the HDR icon did not show up in Chrome. Oddly enough after some time it showed as HDR in the YouTube app on my android phone, but still not in Chrome. Then it worked in Edge on windows, and while I was googling why HDR could work on Edge and not Chrome, I went back to Chrome and to my surprise the HDR icon finally showed up in Chrome for windows, after so many failed tries. So it seems it takes quite some time before the HDR processing is done.
I also tried to use PQ as transfer characteristics but it came out quite a bit darker than what I saw in VPX. The HLG setting was pretty close to how I graded my log footage in VPX.
This was just to make the HDR icon show up, now I will try grade some more content in VPX and see how I can make it look on YouTube.
The colors in the screen capture is completely off, so don't take this as a reference. But the important thing is the colors are no longer "just" rec. 709. But HLG / bt 2020

Hope the post is readable, I also struggle with the grammar in my native language :-)
