ffmpeg error "corrupt video... can't detect number of frames"

[ItsMeTho]

I can't add video exports from Davinci Resolve no more so it seems.. idk if it's the export or ffmeg or roop.

I've tried re-encoding some and only 1 file worked after that. But can't find the logic. Especially because it's not just new exports.

Downloaded videos seem to work.

Terminal says
[mov,mp4,m4a,3gp,3g2,mj2 @ 000001ccba71bfc0] moov atom not found

Any ideas?

Download and install Avidemux.

Start Avidemux and open your problematic video file by dragging the file and dropping it into Avidemux.

On the left side of the software UI panel, set the following:
Video Output: Copy
Audio Output: Copy
Output Format: MP4 Muxer
Output Format > Configure > Optimize for Streaming > set to "Move index to the beginning of the file" > click "OK"

Then click the "Save Video" icon at the top left that looks like a downward arrow pointed to a rectangular box to save the new video file. That should take about one second, very quick.

Should fix the error "moov atom not found". I haven't had that error since.

I've been getting this, too, over the last couple weeks. Not sure if it was an update, but it never happened before. Regardless, to fix, I go to the Extras section, load the video in the top section, pull down the Video/GIF section, and run Repair Video. Has worked every time and is really quick. When done you can download to wherever you want, then upload to the main screen and swap away.

same here, repair fixes it. and its only 1 out of 5/6 video's, but strange indeed
