It would occasionally be useful for me to minimise this auto-fade down to 0 ms in order to maintain continuous audio despite splitting.
I’m doing a complicated cut of piece-to-camera narration, PC desktop recording, and other graphical overlays, enhanced with externally recorded narration. After synchronising all the clips in time, I need to group them all to keep them in sync. I then do a complicated cut of video components, requiring lots of splitting. Splitting a grouped block of files also splits my master audio narration. Mostly it is between sentences, so it’s no problem, but sometimes during a complicated video edit, a split happens in the middle of important audio, and the auto-fading makes a noticeable warble in the sound. Reducing the auto-fade down to the minimum of 1 reduces the impact of this, but it’s not perfect. A 0 ms auto-fade would be better when you want continuity of split audio, however, I wouldn’t want to change my system setting because it is good most of the time. To work around this, I do an L-cut by ungrouping my master audio file, and either relocating the split to a nearby moment of quiet with a couple of audio trims, or delete the audio from one side of the split, and reform it by trimming from the other side of the split.

I found the cause of the problem, so here’s a followup in case it helps anyone else:

The computer is a DELL Inspiron laptop, and had Dell Backup and Recovery software preinstalled.
This software had been continuously backing up the hard drive to itself(!) with no regard for available disk space(!)
The software creates a hidden folder on the hard drive at c:\System Recovery. To see it requires modifying Windows security settings for the folder and subfolders (which takes some time to do, and gets annulled if you restart because of the software ‘fixing’ the access settings upon reboot). This folder was taking up 194 GB of space on the hard disk.

Uninstalling Dell Backup and Recovery also cleared away the C:\System Recovery folder, freeing up most of the space on the hard disk.

Bumping this thread because I have the same issue.
My project has twenty-one 4GB 4K MOV chunks, and I’m wanting to join them (into two files – one file for each half of a concert).
I just tried using Applian Replay Media Splitter for Windows 3.0.1703.9 and for some reason there are a lot of problems with the output vision. (My footage is in25 fps, but after joining, there are 2 corrupted frames after every 30 good frames.)
Does anyone have a good solution for joining MOV files without re-encoding?
