How to read .tsv videos

I don't know this action camera... and I haven't found much information on the internet about .TSV files except that the codec used is H264 as stated on the official site (?) :
- http://www.apemanelectronic.com/apeman-a80-4k-action-camera-20mp-wifi-waterproof-sport-camera-ultra-170o-wide-angel-lens-with-2-inch-lcd-display/
- http://www.apemanelectronic.com/apeman-a80-camera-user-manual-manual-of-apeman-a80-a70-a66-a60-action-camera/

I'm afraid I can't help you any further :(
However, since there are quite a few videos filmed with this camera on YouTube, I think it can't be that complicated....
Good luck despite everything.

PS: If you want, you can privately message me MP, for more confidentiality, and if a file is not too large, maybe you could send me a small video via a temporary storage site, so I can try to see what I could do on my PC, but I'm not forcing you to do anything ;-)

TSV files can refer to two types of files: https://fileinfo.com/extension/tsv
- office files
- video files (especially from satellite receivers...)

Although I don’t believe it too much, have you tried with MPC-HC / Media Player Classic - Home Cinema?
There is a portable version on the official site: https://mpc-hc.org/
I suggest this media player because with real UHD/4K files (the aperman a80 doesn’t do it, see here) it can play videos that VLC fails to...

I’ve also seen that TSV files could come from recordings of satellite decoders, but that video files seem to be encrypted and that’s why we can’t read them on a PC :(

Then I saw this tutorial in English with the name of software that could convert TSV files, but I don't know if it's free: https://www.idealshare.net/video-converter/convert-tvs-to-avi-mp4-wmv-mov-mpg.html
This editor also offers a player (free or not) so try it if you want...

That’s for playback...

As for the conversion or processing of video taken by a camera, there are two ways to do it, based on editing software:
- transfer via USB, by inserting the SD card if the computer has one or other
- we import it directly into editing software
Have you tried this second method of transferring videos taken by your camcorder to your PC?
If you don’t have a paid editing software, there are quite a number of free ones, see non-exhaustive list: https://www.clubic.com/telecharger/actus-logiciels/article-723425-1-montage-video-selection-logiciels-gratuits.html
I suggest, for example, VSCD Video Editor, ShotCut, OpenShot, GoPro Studio, or the free version of VideoPad Video Editor or another one.
I’ll add Hitfilm Express, which requires quite a powerful machine if I remember correctly: https://fxhome.com/hitfilm-express
But it’s up to you whether you want to install them to test or not...

I think I'll stop my help here because everything I’m telling you, you probably already know... and since I don’t have a TSV file to test, I can’t really tell you what is possible or not to do...

To finish, could there be a setting in your action camera to put the videos in another format?

Thank you for indicating the solution found, which is not complicated to do either ;-)

I wish you a good continuation,
Ciao
