What file format is thm

THM is an index file for MP4 or MPG video files.

Some video players require not only video files in MP4 or MPG format, but also an index file in THM format to play.

A file in THM format is actually a picture in JPG format, which you can open and view with ACDSEE. When the MP4 player cannot play MP4 or MPG files, it is because of the lack of this index file. Just find a picture in jpg format and change the resolution to 160*120, and then change the file name to be consistent with the name of the mp4 or MPG file that needs to be played. Change the extension to THM and you can play it.

The thm file generated by a digital camera is not a video file. When the camera records a video, it will generate two files with the same name. The larger one is the video file. If you save the video on your computer, the smaller thm file will be generated. It can be deleted. Without that file, the video cannot be played on the camera, but it will have no effect on the video itself.
