I encode my longplays with megui and I have pretty huge files :) Currently I record Warcraft III and I found the function Preset - it was at Ultra Fast from the start so my question is If I change it to Medium could I get smaller files without big change in quality?

If someone could tell me how to reencode an existing mkv file because when i tried the new preset the older mkv files could not mux with them and the video could not be watched. The problem is that I do not have the avi files from fraps and I do not want to record the whole thing again so please if someone could help me I will greatly appreciate it :)

Join the IRC, and the staff will help out :D

I think I got it but after the whole encode (which is very big) I will post again if I need further help :)
