Re-sizing MPEG 1 in Compressor

[Rafael Amador]

Hi Benjamin,
That is the only standard size for MPG1.
You can try ffmgx if you want to customize the size.

I could be wrong about this but IIRC you can make a duplicate of the locked preset and set the new version to just about anything.
Be aware, however, that MPEG1 is a standard. if you change the preset, you’re not longer creating a standard-spec file and that may or may not play on your target machine or applications.

From what i’ve seen so far, opening an MPEG1 is much easier than making it. If I could go from FCP to a 640×480 MPEG1 without doing any intermediate conversion, i would be the happiest editor alive…
ffmpegX looks interesting, I’ll check it out tomorrow, but it still needs a MOV to start with. You can say I’m lazy, but i like to think I’m just impatient. And the clients as well.

Hi Andras,
MPG-1 is a kind of relic and probably yields the lower quality that you can find among the compressors.
Try any application that claims to make VCDs. that’s his format.

IMpatient?
Buy a PC. you can get a card that does MPEG1 in realtime or even faster. No such product for the Mac.

MPEG1 is the oldest, lowest common denominator for minimal CPU usage with barely acceptable video quality and near universal playback ability.

Toast will do VCDs.

Sorry this may be a little late… but you can do it by duplicating the mpeg1 preset in compressor, closing compressor, find that preset via MacintoshHD > Users > (your user name) > Application Support > Compressor and open it with text edit and change the parameters according to what you want. (I make 640×480 with 3.5Mbps adjustments to it.) Save that file and when you open Compressor again your preset will be updated. This wasn’t my idea i found the answer on apple’s support forum:

hope this isn’t too late!

Thanks for this – very useful when you are sent specific output settings to conform to – we don’t always have the choice of the best output settings ourselves!

Just a small correction for OS X users, I found the file in :

MacintoshHD > Users > (your user name) > Library > Application Support > Compressor

Thanks for the great answer! It’s so liberating.

Tip: When your trying to make it ‘100%’ put ‘-100’
