Subtitle frame rate converter

Sat Sep 10, 2011 11:53 am

I know it is not related with Mirillis or products. Eventhough, I believe I will get an answer.

I would like to have a suggestion for a free program which will just change subtitle frame rate, and save that subtitle file with new frame rate.

I know if I do google there will be lots of such programs, but I just cannot be sure they are working. Also, I could not find one that is easy to use, yet.

There are a lot of types of subtitles.
The most popular are srt and ass/ssa - they just doesn't have fps. They have timing - time when they should be shown. E.g. if you doubled video fps via interpolation timing would be the same. But if video framerate was changed just with speeding up/down (e.g. PAL's 4% SpeedUp 23.976 -> 25) timing would be different, and you have to change timing. I don't know special programs that could do such thing - but at least you can stretch them when muxing to mkv with mkvmerge.
Also there are other formats (like .sub), that are using frame numbers. You can import them to Aegisub (and choosing fps of video they are made for, likely to be 23.976 or 29.97) and export as .srt or save as .ass.

One of the best is Subtitle Workshop version: 2.51

Just open .sub file with Subtitle Workshop then save it like .srt and you will have the same subtitles with right timing.

Yes it is what the users expect from you. Mirillis has a growing fan base because the fact that their product is light and can use hardware decoding elegantly, thwarting similar offerings from other companies in design, approach and the whole package experience we have come to expect and love.
