The "VC" nightly works better for me
I'm hardcoding subtitles to a video and re-encoding them
(not a fan sub, just a small demo video)

The other versions are crashing as soon as i press the save button
The "VC" ones work fine

I give up with this garbage constant updated rubbish! So much potential, so many crashes due to bugs!

The truth is people complain about this because it is full of buggy code and never seems to work that well even in a stable version. It's a long standing joke even at Doom9 forum. Ask there what you think of this and most honestly would say the same. If it works for you then you are lucky!

Review by Tony Li on Nov 13, 2018 Version: 2.7.1 OS: Windows 8 64-bit Ease of use: 1/10 Functionality: 1/10 Value for money: 1/10 Overall: 1/10

I just edited a video, made a few dozen cuts, and when I went to save it the whole project disappeared. I must have misclicked the save, hit the "close" link next to it and lost everything. No ability to revert, no confirmation to save or clear, the entire video is simply gone. So if you like to risk the loss of hours of work just because you misclicked a few pixels, this is the software for you. But it mostly certainly is not the software for me.

Review by Will on Nov 4, 2018 Version: 2.7.1 OS: Windows 7 Ease of use: 1/10 Functionality: 1/10 Value for money: 1/10 Overall: 1/10

Can't figure out all the complainers. They probably haven't built a thing in their lives! The author obviously cares about his/her creation and has spent much time working on fixes. Worked first time for me, splicing a section from a .TS file and saving it as an .MP4. Very slight lag in the speech lip movements in the saved file which is an improvement on a couple of commercial programs I've been trying. The fact that that this software comes free of charge is much appreciated. Well done!
