Older movie files from harddrive faile immediately to process

[Pete4K]

I tested to process a 720p anime file to 4K, which is longer on a harddrive. To play this file works without a problem, but when I try to start a process it fails immediately. When I try to download this file again, the process runs and works. What can this problem be? I think I saw this before with some other files, too.

After reading the steps you took I'm still a bit confused with what you have tried exactly. Can you provide the logs for when the processing fails?

The logs:

That resulted in failing the process immediately.
The file was an mkv 720p file, but like I said, when I try to redownload the file from the web, it works. And the file itself works.

But for every file ever I still get these errors, but the process works. What does that mean?

I used the 10-Bit option of libx265 and the crf values 23-25 for a Real ESRGAN process. These 3 files were processed successful.

Seems like the output container format doesn't support your subtitle format. You can ffprobe the old one and the new one to see which formats they are using, respectively.

[Pete4K]

That is the same file (mp4-file named "One.Piece.0003.Morgan.gegen.Ruffy.German.AC3.ML.720p.WEBRip.x265-FuN" from the harddrive with two critical errors, one for the file in crf 23, 10-Bit and one for the same file in crf 23, 8-Bit (Auto):

Later I will write the logs for the same file as a new downloaded one. The problem shouldn't be the subtitle format or does it change the codec when the video remains a longer time on the harddrive? The old file is not broken, too, because I'm able to play it fully.

[Pete4K]

I see now that the new loaded file is a MKV file. Ist IT possible that it failed, because it was an MP4 file before.

[k4yt3x]

I would guess that the subtitles are of different formats in the two files. Can you run ffprobe against the two of them and paste it here?

Here's a template you can use:

ffprobe -v quiet -count_frames -print_format json -show_format -show_streams -i video.mp4

[Pete4K]

Can I write this as commands in the Programme?

[k4yt3x]

No you'll need to have FFmpeg installed. You can also just send me the video. Upload it to google drive or https://wormhole.app or something and paste the link here or email it to me. I can take a direct look at the two videos.

[Pete4K]

Ok I'll send it per Wormhole in a few hours.

[Pete4K]

Here are both files zipped: https://wormhole.app/rMQRZl#sEiZkKfcd3l64ZHj_eKmuQ
They are named, which file is failing and the one which works.

[k4yt3x]

Seems like upload is incomplete?

[Pete4K]

Ok I try again in a few moments K4YT3X ***@***.***> schrieb am Fr., 7. Feb. 2025, 18:30:

I took a look at it. Here's what's happening:

• The failing one (MP4): Subtitles are in MOV text format. MOV text is not supported in MKV.
• The working one (MKV): Subtitles are in ASS (Advanced SSA) format. ASS is not supported in MP4.

Basically, set the suffix in encoder option to be the same as your input if it fails with a similar message. Your subtitle stream was just not supported in the output container format.

So, if you use the original failing one and set the suffix to mp4, it should have worked.

[Pete4K]

Ok. Thank you very much!
