Best program to use to make flv and mp4 vids to fill in some blanks

[SupraKarma]

I'm still missing some videos for MSX2, and I thought I'd make my own. What is the best program to use? I want to make vids in the same format as emu movies, with some in game action, then the title screen shot.

I used MAME in-game recording, and then edited the results afterwards. Motoschifo (did I spell that correctly?) at PD wrote some scripts for this purpose.
