How to frame-cut videos with subtitles

Hello Ghred1147,

The editing MKV file with subtitles is like the editing of any video file in Video Splitter.
You can see how to edit files here:

If there will be any questions after this video, please contact us at support(at)solveigmm.com and I'll send you the detailed instruction on how to do this.

I searched and searched to find a video editor that provides frame-by-frame cutting of MKV or other video files that contain text-based subtitles (srt/ass,etc). I was assured by Solveig advertising that this (non-avi) Video Splitter would do just that.

However, I can find no documentation anywhere about how to do this. Please either explain that in your replies or direct me to someplace I can find that info. If this can only be done with files that contain permanent, embedded subtitles, this application is utter garbage! I have at least a dozen apps that will do that already, including quite a few open-source/freeware tools!

If your tool doesn't do this with MKV files or the equivalent, I want my money back.

Thanks
