Gigantic file sizes from VirtualDub

SB118 · 5 May 2009 at 13:04

Right, i have a piece of video that is 15 mins long, 28mb in size. I need to greyscale it, decrease the brightness and up the contrast to make something viewable.

I've done the alterations without a problem, however, when i try and save the new avi file it dumps out at around 3.5gig. Which is quite big for a 15 minute file.

Only used Vdub for joining avi files before now, so i'm totally at a loss.

Help!

you need to install something like xvid or ffdshow and set the video compression to around 1200kb/s using xvid or ffdshow xvid

also, an mp3 codec is useful for compressing the sound too.

if you've never done either, look for a virtualdub compression guide

Bingo, cheers

Found ffdshow in a menu and the file size dropped down to 40mb, i can live with that.

Now i can give the rozzers the footage of the vandalism on the wifes car :mad:

better still (for them)

i'd import it into windows movie maker and save it as a high quality WMV

they're more likely to be able to play it..

also, post it in GD..!

It's a scabby video anyway, tied in to the cheapo camera the pub next door has and i couldn't even see it happening until i tweaked the colours.
Doesn't help that they haven't cleaned the camera in a couple of months either

it's uncomressed, use a codec and save it as a compressed file

OR

compress the huge AVI with another program such as tmpgenc
