Was hoping someone could shed some light on a problem I'm having...

I capture game play footage with fraps 2.1, then open and edit it in Studio 9...

when I go to output the video, AVI is extremly large, and mpegs are smaller but large too.

(ie: a 15 minute video will render AVI at about 8000 mb's, while mpeg will render in around 300 to 400 mb's.)

I've tried changing the settings using different codec's... but there all pretty big, including DivX, which is my favorite codec.

I know I've seen plenty of other video's at around 700x500, that look good and are under 50 mb's...

what I'm I doing wrong? anyone got any advise or suggustions?

thx in advance.

Maybe, but how long were they... not very is my guess! :-) Some people seem to have more luck with their codecs & compression that I did, but I used to guestimate that 1 minute of fairly good quality compressed video would "cost" about 10Mb.

All the really long or high quality movies I've DLed have been much more than 50Mb.

Andrew is correct, 7-10 mb per minute of footage is about right.

My first movie 'Carrier Ops' was 5.5 minutes long at 43mb. My second 'Retaliation' was 6.5 minutes at 37 mb. The second was smaller because I used flash to make some screens where there were letters being typed on the screen, like a teletype. Those take up less space than video.

DVD (MPEG-2) video streams for NTSC are 720x480 and range from 3000 kbps to 8000 kbps (or roughly 375 to 1000 KB/sec. 375 KB/sec means 22.5 MB/minute, roughly.

If you drop to Windows Media and go NTSC standards, you can get down to 384 kbps with Windows Media Video 8). That's 352x288, which is also a 'broadcast standard', about 2.8 MB/minute. Frame-rate is gonna be choppy, though. You can get as high as 1400 kbps. You can also step away from NTSC and go with the Windows Media Vidoe 8 LAN settings, which get you as low as 100 kbps, but quality is going to seriously suffer there. 320x240, lower frame-rate.

You could do SVCD quality, which is just slightly better quality than the Windows Media Video 8 at 384 kbps - anywhere from 2000 to 2500 kbps.

MPEG-1 (VCD quality) is 1150 kbps. VCD is 352x240 for NTSC. This is roughly comparable to VHS. You're looking at around 8 MB/minute there.

And finally, you can look into other codecs like Divx or Xvid, which can achieve better compression than WMV and MPEG, though there are certain quality tradeoffs to be aware of.

Hope that helps.
