Hi all,
I have a number of MKV files (H264 MPEG4 AVC Codec) That are currently 800MB or 1.2GB in size and I would ideally like to compress them to around 400MB each - the format of which I am not too fussed on and I am happy to make the video resolution smaller as some are 720p which isnt needed.

Any advice on the best way to go about this? Possibly by batch process? I assume I will need a beefy machine for such a task?

I am running Windows machines.
