MTS video

[novaca]

Is there any way to make the Quick View panel play MTS video files (from Sony video camera)? When I hover over the file's thumbnail in the File Window, the "jumps to next frames" preview appears. In the Quick View panel there is only a static preview (thumbnail). The MTS format is listed in Preferences - File Formats - Video/Audio File Formats. The video overlay icon (play arrow) is not shown for these files.

Many thanks

Microsoft lists this container format as currently unsupported for the Media Foundations API IMatch is using. This format is used by SONY/Panasonic only, I believe.
See https://learn.microsoft.com/en-us/windows/win32/medfound/supported-media-formats-in-media-foundation 

IMatch supports most variants of .MP4, .MOV, .AVI, .ASF, .WMA, .MPG, .WMV and .TS at this time.

Consider converting your MTS containers into another container format like MP4 using the free FFMPEG software.
There are numerous tutorials out there which explain how to do that on the Windows command line. This is lossless or can even produce a compacter video file without visual quality loss.
