I've got an MP4 Video here that cannot be opened by any of the following programs:
VidCutter, HandBrake, vlc
I recorded this by using iFun Screen Recorder in h264 and even this cannot open it.
Other recordings work as they should. This one might have not been saved correctly maybe because there was not sufficient space to go on recording.
I have tried opening it in vlc by converting/saving it without any luck.
Wondershare Repairit as well cannot repair it.
Do I have a chance to recover it and if so how ?
Thank you for reading in any case.

Ok, here we go:
Analyze analyze (-a) shows me this:

What do you mean by working template ? I have just started untrunc-gui and loaded the file.
You can try recover_mp4:
It's a command line tool. You need to extract valid metadata from a sample file (a video recorded with the same settings as the corrupted one). Then extract video/audio streams from the corrupted file. And then save these to a new file. Here you can find a more detailed guide on how to use the tool (see method 2):
Well luckily I have at least another file of same type made by iFun Screen Recorder.
So in the tab called Repair I put one of these files as a reference file and the damaged file as truncated file.
This is what I got after pushing the Repair button:
The fixed file works indeed but the sound and picture is asynchronous. It seems that the picture is constantly some seconds too late compared to the sound.
Ok. Additionally I have a further question:
Which program would be ideal to show separate tracks for picture and sound so that I could try moving the sound in small steps back and see instantly the result before saving the complete file ?
