I've spent the entire day trying to solve this issue, it seems paranormal but (sadly) it's true and I didn't find a way to solve it. Yesterday I recorded a very important video using my Xiaomi and Quick Video Recorder (I used it more than once and everything has always been great), I had something like 3Gb of free space but I didn't check it and I was recording with high quality. Android told me that was running out of space, so I suddenly stopped recording. I checked the video and used VLC to replay it and everything seemed to work fine.

After about 30 minutes, the file was missing. I checked everywhere, rooted the phone and tried with recovery applications such as Dr.Fone, but the file is completely disappeared. To be 100% sure I didn't dream it I also checked on Google Takeout and it confirmed I actually used the camera during that time and suddenly opened VLC to replay it...

How's that possible? Does Android delete an entire video when it's too large? Is there a way to recover even a small portion or to show logs of camera activity to understand where's the file?

I didn't know what to do so I opened adb shell and tried with ls -Rlat | grep '2019-12-18\ 17:' (I was recording around 5pm) and that's the result:
