My first video - HUGE MPG file

sws1 wrote on 2/3/2004, 1:30 PM

I just created my first movie. I took 35 minutes of DV from my camcorder into MS, chopped it up, added some effects, and some audio extracted from CDs.

Now, the video is 12 minutes long and includes 3 full songs taken from the CDs.

I rendered to MPEG-2, and the file size is 700 Mbytes. That sounds extremely large.

While I didn't save to AVI, I seem to recall the estimated size for AVI being much smaller than MPEG-2, which makes no sense to me. (If I'm not mistaken, the total size of my clips, pre-edited is only 200 Mbytes. Could be wrong about that though.)

Thoughts?

i don't think 700 MB for a 12 minute video is unusually large.

I'm not sure about mpegs, but a 30 DV-AVI would be closer to 12 gig.

DV .avi is about 13.1GB/hour, so 12 minutes worth would be about 2.6GB

The size of a 12 minute MPEG file would also depend on the bitrate used.

12 minutes of 1Mbps video / 128Kbps audio = about 101MB
12 minutes of 2Mbps video / 160Kbps audio = about 196MB
12 minutes of 4Mbps video / 192Kbps audio = about 377MB
12 minutes of 6Mbps video / 224Kbps audio = about 560MB
12 minutes of 8Mbps video / 224Kbps audio = about 740MB

I checked my files. The original files add up to over 7 Gbytes. The MPG 2 is around 600 Mbytes.

I'm going to create an AVI file to see how large it will be.
