use virtualdub (http://www.virtualdub.org)

open the file, go to Video ->Filter -> Add ->Resize
and pick the dimensions

Can I use this program to change the MB size to this too?

yes, but MB will also change depending on the compression/codec you use.
under the same Video menu there is a Compression thing.

I know this tutorial is really about adding soft-subs-----but it shows you how to resize the video too.

hi. is there a way to re-encode 700mb avi into 350mb avi with the following video encoding preference?

codec: xvid
type: video
res: 640*352
frame rate: 29.97fps

codec: a52
type: audio
channels: 2
sample rate: 48000Hz
bitrate: 192kb/s

setting: has index_is_interleaved (what does this mean?)

which is the best and fastest program to do so? is there a way to specify a fixed size?

I would lower the audiostream to 96~128kb/s. You're sacrificing a lot by reducing 700 to 350mb.
The mbs you've saved with lowering the audiostream can be used for the videoquality, if you know what I mean.

video quality in terms of resolution or frames per sec?

You cannot evaluate video quality just by resolution or framerate. You have to avaluate by using filesize and bitrate.

Encoding tools measure (video) quality of avi files in bits per pixel. where pixel = width*height*number of frames and bits = filesize(in bytes)*8.

Good values are between 0.2 and 0.3 (check the doom9 website or forum for details)
Acceptable/watchable values are probably between 0.15 and 0.2 ... Anything less is to be regarded as "eye cancer".

GSpot v2.5 lists this value as "Qf" (frame quality).

For audio I'd recommend 96-128kbps MP3 for low quality and 128-192kbps MP3 for high quality files. If you use the AAC codec smaller bitrates are ok. When using AC3, especially multi-channel audio, you need higher bitrates (i.e. about twice the bitrate).

is AAC or MP3 a better audio encoding?
is there a way to convert from:

audio: MP3 to AAC with the same video quality and fixed size ?
or rather a lower audio quality 350mb file to a 350mb file with better audio?

Hello,

I would like to resize the Goong videos as they are too big. Half the size would be good.

Could anyone tell me how to do it???

Thanks Big Smile

Q5. How do I convert or re-encode AVI ...
ANSWER:
There are many good guides on the internet which describe how to convert or re-encode various types of media. Use google and search for "guides" or "tutorials", and include the type of media you are converting to and from.

The following sites contain numerous, step-by-step guides (often with pictures and the needed tools):

www.doom9.org
