Why should that be easier?
I still don't really understand, what you want.
I imagine, you want to add a subtitle to a part of the video, am I right?
I have no idea how or if Bandisoft is gonna be able to add a subtitle to the video...
Maybe they can do it, like they do with the logo function in Bandicam...
You know, creating a subtitle or a font or whatever from your very own settings (in my opinion) is much easier than translating a file to your software.
If I would be the programmer, I would
1. Create a list that contains all of the Labels / subtitles, with its associated video-position.
2. Create a Label or just a variable with the associated settings (like a list that contains the font, the size, weight and slant).
3. I then would make an image file out of that, which I would combine with the video (like an image of all these subtitles)
4. Then I could just cut those together with the video and then you have it.
I don't know how far you could combine that with the file format.
Hopefully Zun or whosoever is the forum manager of Bandisoft will be back from vacacion soon.
