Deciding of the weight of a video

[randywest]

I have a movie of 650 MB who is an .mpg. I converted it to an .avi with Virtualdub 1.3c and now the weight of the video is 820 Mb. My question is, can we decide with a program how much MB the video is gonna weight? Also, I tried to convert with WinMPG Video Convert the same .mpg to a Divx but the video was upside down. Why?

I don't know what you did to make the AVI bigger then the mpg, but as for the video being upside down, I've seen that happen. It's not actualy upside down, for some reason it gets flipped during playback. I normaly try a diferent player and that solves the problem. Try "The Playa" from divX

You are looking for a bitrate calculator, check the tools section to find one that fits your needs

When you converted to avi you decompressed the mpg, so naturally it increases.

It's like changing an audio file from mp3 to wav.

What you have said is wrong, the original file was 640mb and if this was decompressed if would be many gigabytes in size. He has obviously just re-encoded it to AVI format, probably DivX, which is still compressed video. It's more like converting MP3 to OGG

If you used smaller bits for your videos, they would weigh less.

Crazeplaya, he said it increased in size and he used "Virtualdub" which decompressed the file. "THEN" he used WinMPG Video Convert to convert to DivX.

An mpg doesn't have to increase massively in size if the original video file has a high bitrate hence NOT heavily compressed at all, or is short in length.

Maybe randywest needs to include more info.

The reason why I decided to convert my .mpeg to an .avi is when I was reading the movie and tried to seek or forward, it took ages before the video played again. If someone can tell me how to fix that instead of converting? If I have to convert to an .avi or .divx, how do I do to keep the output file as the same weight of the input file? And why when we convert to .divx the video is upside down? The video is an MPEG 1. Why when we convert to MPEG 2, there's a kind of hazy line on the bottom of the vid?

OH, you have problems, upside down video, hazy lines. I remember when I had a brightness problem on my MPEG2 files. It took many encodes to find the settings that were causing it. I hope you don't have to figure out this problem on your own, you'll end up necking yourself through frustation, I "JUST" made it through my problem.....

I don't know anything about your upside down problem, I don't encode to DivX, you could just turn you monitor upside down?. That Hazy line on your MPEG2 files, what exactly does it look like? Are you talking about a slight flicker. Cause I have noticed that on my MPEG2 video files which only show up when being played through my TV. It doesn't happen on 1 other TV that I have treid it on, or is it the DVD Player?
