    So I’m having some problems exporting this project through H264 (I keep getting error code 3), so I’m gonna try exporting Prores even though I really wanted to avoid it.

    What’s irking me though is the colorspace. All my source footage is 4:2:0. Prores is 4:2:2. For the final upload to YouTube I need to re-encode with AME, which basically sends it back to 4:2:0. Wouldn’t I lose a lot more color information? I wanna make sure I’m not losing too much by doing all this, I doubt it’ll fix my problem anyways 😛

    Hi Antoine!

    “Why do you think you need to re encode before final upload?”

    Because Prores files are too large, plus uploading to YT will take way too long.

    “So you want to do PrPro project -> ProRes –> H264 for Youtube upload, is that it ?”

    Yep. Only reason I’m doing this is to get past the error code 3, it’s still rendering as I’m typing this so hopefully it won’t error out.

    Hi Ethan

    This was a problem that crept in back with AME 2017.1 and was related to the bitrate being too high for the conversion to work without giving an error 3 and failing. Bitrates over 192 would error. Adobe suggested at the time to set the profile/level to Main/5.1.

    Don’t know if that would work here?

    Prores export worked fine but I ended up having to add a segment so I have to rerender aaaaaa lmao

    When I export 4k60 through H264 I’m exporting it at 90mbps High profile. Bitrate shouldn’t be a problem here.

    I might try transcoding my footage to Prores incase this happens again. I transcoded my footage with FFMpeg and even though the footage looked perfectly fine in MPC, Premiere has this awful color shifting.

    Attachment 1 is what it looks like in Premiere.

    Attachment 2 is what it’s supposed to look like. This is how the Prores transcoded footage looks through MPC, although this screenshot is from the original H264 video inside the Premiere project. Notice the reds in the dude’s hoodie and his skin tones.

    ffmpeg script:

    -c:v prores_ks -profile:v 3 -qscale:v 9 -c:a pcm_s16le -threads 12

    Anyone know how to fix this? I know this has to do with color matrix. Adding the rec709 filter in my script doesn’t work.

    Have you tried turning off the GPU acceleration? Render with Software Only? Will take longer, but may have fewer errors.

    When I updated Premiere to the latest version at the time I guess it got borked. Renders took took long (4x as long when it usually takes a tad longer than the video’s duration) and I had that error I was talking about. I just updated it and thankfully it took about 30mins to render and there was no error.

    Then again I don’t even know if its a total fix, I’ll keep testing.

    Also what about my Prores color issue? (see last post)
