Canon video repair
Canon video repair: what it usually means
Canon camera clips can be damaged by sudden shutdowns, low battery, card write problems, or interrupted transfers. The file may be present but unreadable in QuickTime, VLC, or editing software.
If the file has real size, there may still be recoverable frames and audio inside. The safest first move is to leave the original untouched and create a separate repaired preview.
Do not trim, re-export, repeatedly convert, or overwrite the damaged file. If you need to experiment, work from a copy and keep the original exactly as it is.
