I've set up MCE Buddy to compress recordings I move to a particular folder. I just did a test using MP4 Normal however and it only compressed from 1.32GB to 800MB, which I don't think is particularly good, especially as I found in the past that MP4 can give smaller files than DivX/XviD for equal or better quality, so I'd think it could go at least to 50% of the original filesize and still be OK (bearing in mind it's only SD Freeview to start with).
I found this table of conversion times https://mcebuddy2x.codeplex.com/discussions/395633 and the only one that stands out as being smaller is DiVX AVI Normal but that takes over 1hr (it doesn't mention what CPU is used).
So does anyone know if it's possible to get both high compression and good quality (which I think can be achieved with MP4) but also quick compression times (I'd say up to 30mins is reasonable), perhaps using the GPU (HD4250) to assist? I don't have to use MCE Buddy and can just setup a manual process to be run if that's the only way.
