Videos getting corrupted

Issues & Assistance
1

When I move files between my computer and diferent SSD cards, commonly there are videos that are getting corrupted.

$ mpv input_video.mp4
[ffmpeg/demuxer] mov,mp4,m4a,3gp,3g2,mj2: moov atom not found
[lavf] avformat_open_input() failed
[ffmpeg/demuxer] mov,mp4,m4a,3gp,3g2,mj2: moov atom not found
[lavf] avformat_open_input() failed
Failed to recognize file format.

Exiting... (Errors when loading file)

With vlc gives similar error.

I have Garuda, with btrfs and cryptsetup. I don't know where the problem is coming from.
Also, I can't recover the videos, I already tried:

ffmpeg -i input_video.mp4 -c:v libx264 -crf 18 -preset slow -c:a copy output_video.mp4

Is anyone else having this problem and know how to solve it?

What is your method for moving the files?

3

I already tried moving from dolphin, mv and rsync. All methods let some files corrupted

4

I think there is a missing e after don

find. -type f `; do NEWFILE=`echo "$FILE" | sed 's/.mov/_NEW.mov/g'`; qt-faststart "$FILE" $NEWFILE; don

Repair with ffmpeg, are the movie files encrypted too and why, if? :smiley:

It seems possible the target SSD is itself corrupted. If it is Btrfs, try to run btrfs check to test.

btrfs check <target device>

It is recommended to unmount the disk first.

the movie files are not encrypted, just the partitions.

Can you explain how you set up this device?

When i was installing Garuda i put the option to encrypt the system.
Then, now I booted from my bootable pendrive with Garuda, opened it:

sudo cryptsetup open /dev/nvme0n1p8 system

I put my password and executed the " sudo btrfs check /dev/mapper/system"
