Conversion usiing VirtualDub - 720 X 560 videos into 640 X 360 videos

[candyman9999]

Hi Folks,

I have a bunch of videos of 720 X 560 resolution videos. All these videos are already compressed. The size of each video is around 40 MB to 50 MB.

Now i want to convert these videos into 640 X 360 (Wide Screen) Videos without losing the quality.

Now i am able to convert them using Virtualdub. But when i use no compression, the output video is rounding more than 5 Gigs.

When i use a compression technique like MSU the output is around 500 MB , quality is good. No loss of quality.

When i use a compression technique like DiVx and FfdShow, the file is around 40 - 50 MB but i am losing great amount quality??

Can anyone suggest a better solution for my problem.

I want the files to remain of the same quality and of same size.

Thanks a lot,
Candyman

I want the files to remain of the same quality and of same size.

It doesn't work that way. They won't remain the same quality no matter what you do and what size you give them (unless using a lossless codec, such as Lagarith, with a huge resulting size). When using very lossy codecs such as DivX or XviD, the quality loss is often noticeable.
