Nice job but still is missing a lot things.
- x264 - the only real and good codec !
- 1 and 2 passes for xvid, DivX and x264
- quality control in encoder for 2 passes encoding to obtain exactly size I want.
- more control how codec should encoding video - for example for x264 should be line command to control all parametrs and maybe simpler version for heck or unchecked what I want to use while encoding.
- creating own profiles for encoding.
That's all for the time being
