Hello guys
Let us say that I have a video file, an AdvancedSubSubtiltles subtitle and from these two things I want to create a hard-subbed video (AVI or MP4) that has the AdvancedSubSubtitle already burned in it with the style, the fonts and the colors.
Thank You

Hello

I don't know for kdenlive, but ffmpeg and avidemux can do

The topic of subtitles comes up every now and again in kdenlive forums.
You can use the titling feature to hardsub videos. But it will be tedious. Why would you want to hard sub the video anyway these days? Soft sub it instead!

I usually suggest people look else where for a tool that is specifically designed for adding subtitles. There are a few OS tools to do this. And they offer the ability to hard or soft encode the subtitles. And they allow you to do useful stuff like insert or subtract time between subs. Give you stats on the characters per second you are setting people up to have to try and read etc etc. ie these tools are probably going to be much better at the subtitling task than kdenlive. This is because writing subtitles is a bit of art meets science.
