Any good ways to achieve quick but high compression of TV Recordings?

[QUOTE="doveman, post: 1021941, member: 67412"] I was asking about compression, so it's quite obvious I was using MP4 as shorthand for MPEG-4 and not .mp4 (and if you want to be pedantic, I would disagree with the statement that has nothing to do with compression anyway, as whether it contains MPEG2, VC1, H264, they're all compressed formats). I said what I want: High compression (i.e. no more than 700MB from a 1.32GB source), good quality (for SD source) and quick compression times (under 30mins for a 1hr programme). I also added that ideally I'd like to keep the subtitles available but I don't know if this is possible. I was wondering if the process could be sped up by using the GPU. I'm not sure the HD4250 could help with this though as it doesn't show the "Accelerate Video Conversion" page in CCC that my 6950 does. I have been able to use the HD4250 to accelerate converting audio files to FLAC quite considerably though. I don't do a lot of compression these days as it's easier to download stuff from iPlayer when possible rather than edit and convert it myself but sometimes there are programmes I want to keep that aren't available to download. I wouldn't say storage is that cheap these days, I don't think it's come back down again since the increase due to the floods and besides, HDDs are just not suitable in my opinion for archiving stuff as they can be wiped so easily so at the very least you'd need two HDDs to have two copies of everything. Mind you, I don't really have much patience for working out which files will fit on a DVD and burning them anymore either, so I'm not really archiving much at the moment. Ah well, probably never have time to watch most of it anyway ;) [/QUOTE]
