Game/App Problem: Rainbow Six Siege
Error Type: Corrupt Video
Video Editor: Premiere Pro
Description:

I record with Action for about over one year and didn't get this problem: after my play session and recording different clips with TimeShift, I closed my game and wanted to rename my recordings. There are a lot oft (not all of it!) mp4-files shown in grey and with no thumbnail. I couldn't open these files with any videoplayer. These corrupted files are not big, but there are "timeshift_xxxx.tmp"-files for every corrupted file and they fit with the size of the files who are not corrupted. I record exact 3 minutes, if something is worth recording.
I copied these corrupted files in an other directory and tried a lot of things. Renaming the tmp to mp4 does not work, trying different video repair software does not work, but there are a lot of online-repair-sites who can restore them and want 25-70 Dollar for every file.

So now my question: the tmp files are there, and they are exactly from the size, but the last finish of "exporting" from action into mp4 is missing. I didn't found any option in Action and the forum to finish the last missing step.
How can I do this? I'm talking about 5 files from 15 I recorded today.

After this, I'm afraid of recording again

I am afraid those files cannot be repaired.

Does the issue occur for every game? Please update Action! to 3.9.1 and see if that helps.

Action creates tmp everytime, after hitting the timeshift-button, the tmp will be rendered into an mp4 - those "rendering" process has to be started. These tmp-files are not empty, the missing process to make a mp4 from this tmp is also coded in the source of the program, so there must be a possibilty to do it.
I would sent those files to you, so you can finish the process. Please help me.

And no, this happend the first time for me, i never had this problem before.
