Freezes when processing large files

[MrD-RC]

I know you’re recommending that people use Alex’s tool. But his doesn’t support outputting to a png sequence or transparent OSD only video.

The only problem I have with your tool is that is freezes when processing large files. The seem to freeze around the same number of frames. I can run a couple of tests to check.

Please could you fix this. Yours is the only tool with a nice to use UI which accepts the avatar font files, and outputs just the OSD. No other tool does this.
