Mpeg 2 HELP!
I have a 40 min MiniDV video and I used compressor to make it an mpeg 2 file. Can someone please tell me how I can make this one about 1 gig instead of the 1.5 gigs that is rendering out as. I already have 3 other mpeg 2 videos that I can’t reconvert so I have to work with this 40 minute video and get it down in size.? I already used A. Pack on the audio. I am using Compressor:
One Pass VBR
Average Bit Rate: 5.5
Maximun Bit Rate:7.0
Motion Estimation:BetterI would normally try out a few settings to get it right but each conversion takes 2 hours and I only have till tonight to get this done.
Are there any settings that I can change to possibly get it down to 1 gig in size? I dont mind going down in quality but I dont know how much to lower the bit rate and like I said Im pushing the deadline and can’t try it out!
Thanks for any tips and setting sugesstions!

Do you think setting average bit rate to 3.5 instead of 5.5 will bring me down a half a gig? From 1.5 to 1.0?
or should I just go down to One Pass instead of the One Pass VBR?
Thanks guys!

I am shooting from the hip as far a space required for a 40 min to 1GB at what bit rate calculations is concerned. (GOP size is also a factor, typically 15, but could also be 12 etc.)
I have found that a CBR of 4 with a GOP of 15 comes out to about 3.8GB for 2hrs.
If you are going to go down to 3.5 you will want to do 2 Pass(for quality), and if you have the control of max rate you will need to bring it down close to 3.5.
Good Luck
