Hi eduo,
This is pretty interesting. I once did a subtitle editor that I never released but use internally. It's pretty similar in concept, having full keyboard control, lots of visual feedback and sync features (I also added basic fps conversions and sync with separate subs by selecting equivalent start and finish subs).
Yeah, it always seemed to be the most natural way to handle the subs. I wrote my own because I couldn't find one, had you released yours, I'd probably use it instead of developing one.
What did you develop this on?
Native Win32 and C++. Actually, it's a very C-ish C++, I'm not a fan of STL, Boost or those libraries. The video playback is DirectX, also coded natively. Yeah, low level stuff, but it's a lot of fun I think. But that's why the program is so small and requires no dependencies (DLLs or whathever).
Thanks for your input, I'm glad you like it.
