Can someone help me convert a 500mb file to 100mb?

[Coldkilla]

I've honestly really tried. I've spent hours scouring forums, downloading codecs, converters... everything to try and get this 10 minute video down from its 492.06MB size under 100MB. The smallest I've got was 150MB, and even then the video studdered constantly and was in poor condition. I've come here as a last resort to ask for your help.

I created the video in Sony Vegas 9 and saved it in 720P HD (1280 x 720) and it came in at nearly 500MB I have to get it somehow under 100MB in 640x360 resolution.

I'm not asking anyone to upload it for me, I'm simply asking that someone work with me on this, one on one. I uploaded the file here. If you could somehow work with me, telling me what converters to use, what specific settings to use in Vegas, or what special codecs to use in Vegas (freeware or not it doesn't matter I just need to finish this project) I would immensely appreciate it.

I can then later apply this logic to my later projects as I always need to initially save them in 720P resolution and then render them a second time and have the filesize reduced at the 640x360 resolution under 100MB.

Thanks for your time.

What codec is the video currently encoded in?

If you want to do internet distribution at the 100mb size, I'd render it in some variant of Xvid, perhaps. That should get you the size you want. I'd also render it from the original, not from the 500mb file to avoid generation loss, but if it's high quality 720p it won't be a terribly huge deal.

It was all the standard default for Vegas. It's in .avi format, with (I believe) the default given "Cinepak Codec by Radius". When I tried to make the project smaller, I used DivX but ended up getting horrible results. The video skipped back a half a second here and there - and was completely unwatchable.

If I downloaded Xvid, would using that also be a guessing game as to how big it would be when its finally done rendering/compressing?

The original is the 500mb file.

make it 2.5 times smaller resolution, the upconvert back to 720P?

No no, I rendered it in 720P and need to take the rendered video and compress it (while keeping its quality) to under 100MB and 640x360.

I'm not saying render at 1280 x 720, devide it by 2.5 and get 512x288, then somehow rerender it back to 1280 x 720.

You can simply render it from the get-go at 1/5th the bitrate you are currently doing it at. Or you can get a different (more space-saving) codec and render it at 1/5 the bitrate. The resolution doesn't matter for the size; if you use a low bitrate and a high resolution, you'll still get bad picture.

I would not recommend converting the rendered video into a smaller size, I would use the original to avoid generation loss. I don't know how else to put that, but you're lack of desire to use the original doesn't negate the fact that it's better to unless you have some overriding reason

Oh I'm sorry, I didn't realize what "generation loss" was until I heard it in context, so I apologize for that. If I had the original project file still, I would rerender it in 1/5th the bitrate.

But seeing as I don't, I will attempt to do this with the already rendered video and get (hopefully) better results that I have had in the past.

Try using Handbrake (now that it supports files). It should give you the option of picking a maximum file size (I think?).
