I have to record a video to showcase a tool I've made. It's going to include my talking, but I also want some overlay text (subtitles) for people who doesn't have sound.

I'm looking for a program that will let me add a text overlay (as subtitle) for my video, and if possible, export it as .flv .

I've tried this so far:

• Used CamStudio for recording, using their lossless format.
• Converted the .avi file to a .flv using Any Video Converter (free version)

I've been having some trouble with the output of CamStudio, some programs can't play the file right, it skips forward and backward. (VLC, Adobe Media Encoder CS4)

So I'm looking for a program that accepts videos from CamStudio*, can add text to my video, and hopefully export as flv.

*(If that's not possible I'm open for other recording programs).

I'd like to ONLY use free programs, and I'm on Windows XP. Looking forward to your help :)
