MP4Fix usually is superfast
The duration of repair process depends on the size and the type of a crashed file. Generally MP4Fix fixes broken files quickly. It takes from few seconds to few minutes. Nevertheless it happens rarely that MP4Fix is slow.
In some special cases repair process can take even few hours. It might happen if the broken file:
- uses MPEG4 video codec which is much slower than H264 and H265
- is seriously crashed and corrupted data spread around the broken video.
You can use your phone normally
Importantly, you can use your phone normally while the repair runs in the background. The notification appears when it’s done.
You can verify if MP4Fix is working
If the recovered timer is seen increasing (below the progress bar), it means that the broken file is being repaired. Please be patient.
