    It doesn't have to be exactly to MP4 I am just trying to convert my MKV files that I created when I placed my DVD's on my macbook. I didn't realize they would make the movies 11gb's when I can convert to mp4 or m4v or avi at like 2-4gb. I normally use Handbrake, RipIt or DVDRemaster but none are having any success converting the MKV file. Any suggestions or ideas to make this work? Thanks

    ,mkv files can be 1 to 11 GB if you choose the right preset i Hndbrake, no need to re-encode them to another container (.mkv and .mo4 are just containers/formats) using the same codec.

    Though you can try Handbrake to transcode the .mkv files to whatever container you like using a tighter compression using the H264 codec.

    Outside of just clicking buttons I don't know much more for video converting / re-encoding. What's the method to choose another container using the same codec in Handbrake?

    You just could click the Regular > High Profile preset and under Output Settings > Format select the MP4 file format, even if already shown, the container will be changed from .m4v to .mp4, as .m4v is the container for the High Profile preset.

    I just transcoded an .mkv with 70 seconds length to an .mp4 in 6 minutes (4.69 frames per second) and got a 24MB file out of a 43MB one.

    As you can see from the VideoSpec reports I managed to cut the bitrate from 5,095 Kb/s (Kbps) to 2,864 KB/s,

    No need to do so, especially as many paid software titles in the video transcoding business are just SPAM titles with less to offer than the free titles.

    As I haven't used paid software to transcode my videos (work and home), I don't have experience with paid software, as Handbrake, VideoMonkey and MPEG Streamclip fulfil my transcoding needs.

    Handbrake is excellent, works great and is free.
