A compression question
Just when I think I’m getting the handle on this Vegas stuff – POW! I typed ‘compression’ into the Search box and when I got to the bottom of the page after a few hours it said Click here for the next 1000 entries! I’m hoping for some direct help here so I don’t have to rummage through thousands of posts looking for my particular need.
I shoot little corporate training videos and promos for Youtube and stuff. I proxy my AVCHD files and have no problem editing, the renders go great as long as I match my source and I end up with decent looking little 1080p mp4 videos around 300-500MB in size.

It’s been great to project these on the wall from my computer or pop a thumb drive into the big screen TV. So now our company is creating its own ‘intranet’ and wants to put these videos there, but they say I have to get them down to 40-60MB. I’ve tried Handbrake, Media Converter 8, FreeStudio, using my finished project but they still come back at over 300MB. Do I need to re-open the Vegas work table and re-render it differently or is there some simple program that I can drop the finished product in and have it compressed to that smaller size?

File size is determined by bitrate and length of video. It doesn’t matter what tool you use, just make the bit-rate low enough to encode your video length in the size required. Try using a Bitrate Calculator to help you out.

Thanks John! Now this may be totally obvious, but how do I find out what my audio bit-rate is? Once I have the info from the bit-rate calculator, what do I do with it? Should I re-render to those settings or take the finished project to something like Handbrake?

BTW, I’m still running that old Movie Studio HD 11. Management won’t upgrade cuz they’re pushing me to FCP, but I like it here just fine.

Use 128 Kbps for the sake of the calculation.

Use that number as your average bitrate in whatever template you use. So when you select a template, press the Customize Template button and set the average bitrate to whatever you calculated.

If you use Handbreak you want to give it a high quality file to work with. You’ll get better quality if you re-render in Vegas from the original source. This way you won’t be re-rendering an already rendered file and loosing more quality.

John, you’re a wizard! Using the calculator you recommended I was able to take a 4:00 minute 300MB video full of camera moves and knock it down to 39MB and it is more than satisfactory. In fact it really isn’t far from the bigger one at all. The IT guys are now happy that I am not gonna bog down the company intranet with large video files. Thanks again!
