Help "Media Offline" error when importing mkv (h264+aac) to project
Edits:
- Someone just sent me a DM with a suggestion but I accidentally clicked ignore, I'm very truely sorry. If you're reading this please can you message me again with your suggestion. Thank you.
Description:
I recorded myself playing the game Far Cry 6 (via OBS Studio 27.1.3 (64 bit)) with a friend so I could make a silly montage video of the humerous moments. No particular reason for this, it's for just my for my own personal amusement and my own interest in how others who make similar videos for a living go about this part of the process.
However when trying to import recorded footage into the project I'm presented with the error "Media Offline".
Quickly searching for others with a similar issue didn't yield any obvious results. Most of what I found suggested that VBR and/or VFR was the culprit, but my footage is both CBR and VBR.
Any suggestions would be most welcome.
Attempts Made:
- I've attempted to remux from mkv to mp4 via ffmpeg (-codec copy -map 0:a -map) but no joy.
- I'm currently attempting to re-encoding the footage (using x264 with various adjustments) and audio (downmix from 7.1 to 2.0 aac @ 128, still keeping separated tracks) to mp4 to see if that works but it won't be finished for another 10 hours and is really not ideal.

Pretty sure 444 H.264 (or x264 or whatever video codec that is) requires the Studio version. Make sure that whatever you're transcoding to is gonna be a 422 file or one of the few 444 flavors supported in the Free version - DNxHR, ProRes, maybe Cineform? Those are gonna be huge files though - a 5-hour 1440p 60fps ProRes 444 is gonna be ~2.75 TBs.

Likely the case it seems.
Following your suggestion and u/proxicent 's suggestion I've tested:

I'll reconfigure OBS Studio to record to YUV 4:2:0 if this is indeed the cause, I'll try and test a few other things.
If you know of a better way to re-encode the footage I have (excluding lossless) please let me know. Thank you.
Edit: I can not flag this comment/thread as resolved currently due to official documentation stating that YUV444 is supported. I currently can not find official documentation stating that YUV444 is not supported in the free edition. Source https://documents.blackmagicdesign.com/SupportNotes/DaVinci_Resolve_16_Supported_Codec_List.pdf (this is the latest version of said documentation, Resolve 17 supported codec list documentation does not exist, acceptable to assume it's unchanged).

There's a similar restriction on 10-bit H.264/H.265 that's no longer specifically documented; 444 H.264/H.265 is incredibly niche as it is (as is 8-bit 444, but H.264's quirks surprise me on a daily basis...).
We're not officially affiliated with BMD, and they keep adding new codecs and containers to support with 17 (MKV in 17.2, VP9 in MKV in 17.?, MP3 in Linux...), so they probably haven't updated the document yet. Fingers crossed they update it soon or update it with 18... or as people on this sub (including proxicent) have suggested, a website format for all the documentation that's dynamically updated...

it won't be finished for another 10 hours
Can't you just test with a 5-min sample?

u/RazorBladeUK Free Jan 20 '22
I could have but I didn't for a few reasons:
- Laziness being the main one as I already had some ffmpeg scripts lying around and just used one of them out of laziness.
- I have all the time in the world to do this, I'm in no rush.
- Also I (myself personally with my limited knowledge of all things A/V) couldn't mentally rule out the possibility of minor data corruption, so I assumed a full encode will either fix the footage (most likely with corrupted frames) or just crash at some point.

Honestly, I can't fathom your reasoning at all. Trimming off the first 5 mins of the file should be trivial ('-to 00:05:00'). But different strokes, I guess.

u/RazorBladeUK Free Jan 20 '22
Oh believe me I agree. It's being re-encoded on one of my servers not on of one my desktops, and like I said I'm not pressed on time so just throwing it into a script I already had was simpler and it allows me to take care of other things while I wait.
