Hi Olga
There are a few YT videos on basic features of Video Splitter that developer has posted, including at least one showing instructions on how to deal with additional streams embedded in video files. However those guides are a bit misleading, or perhaps they don't fully explain software limitations.
Just like Ghred1147 noted, I have also noticed that Video Splitter does not handle text-based subtitle streams.
Here is a sample video info from ffmpeg:
Notice that it consists of 3 streams.
However when the same file is opened in Video Splitter (ver 8.0.2401.22 as of this writing) , here's what I see:
Notice that it shows only 2 streams, with subtitles stream missing. When the edited media is saved, the subtitle stream is not preserved.
This is a rather
BIG DEAL as the
user is not notified in any way that some content won't be loaded for editing, and hence will be gone from the output. Even more surprising is the fact that even free editors can load and preserve and/or cut tx3g text-based subtitles. This is a major shortcoming (a bug perhaps?) of Video Splitter, and I am not surprised that Ghred1147 was so adamant about it. Although I wouldn't go as far as colling it useless...
