I'm trying to resize an AVI from 1920x1080 to 1280x720 and I found the following helpful tutorial for use of VirtualDub:
http://www.online-tech-tips.com/computer-t...resize-a-video/
If you scroll down you will see the instructions for VirtualDub and I followed them exactly. My input is only about 50 MB but the output is well over 2 Gigs. I learned that when trimming use Direct Stream rather than Full Processing to avoid big files but any selection other than Full Processing and I can't select filters.
Would appreciate any help. |

That's because that site's one of those ones that churn out half complete articles of questionable value
They completely missed out the part where you need to select a compression codec and configure it - without that, virtualdub saves as uncompressed video, which is huge
So, you need to install a video compression codec
Two of the most common ones people use are x264vfw and xvid
x264vfw is a newer one and makes smaller files than xvid, but very old hardware devices may not play back a video using it
I'd try using that first and see how you go
Download and install from here http://sourceforge.net/projects/x264vfw/files/
Then start virtualdub, set it all up to resize
But before saving...........
On the video menu, select 'compression'
On the next dialog box, click on 'x264vfw' on the list at the left side
Then click the configure button
You'll get another dialog appear with all the settings on
Make it look the same as the first picture on this page http://forums.virtualdub.org/index.php?act...1157&hl=x264vfw
Click ok etc until you get back to virtualdubs normal state
On the audio menu, make sure it's set to direct stream copy
Then save the video

Excellent! Output file is now a relatively tiny 6 MB
I had to create a new administrators account in Vista to avoid getting an "error opening file for write" when installing x264vfw, but after that things went smoothly.
Much thanks |
