What is/are the best free tool/tools for editing my videos? I need to complete 4 specific tasks on my videos.


Stabilize. 
Crop to Anamorphic 
Convert resolution up or down to 720p
Convert to mp4 (H.264)


Can someone point my in the right direction to the best free tools to complete these tasks?  I'm using Handbrake to do all my -> mp4 conversion.  I've tried VDUB with DeShaker and Mercelli (not free) for stabilization.  Mercelli only lets me output to wmv or mpg but it compresses and creates a lot of pixelation in the process.  Not to mention it crashes more then Windows 95.  DeShaker is ok, but if the person taking the video moves around at all, it distorts and bends a lot in the background.  I can crop to anamorphic from Handbrake but it doesn't let me scale the videos up to 1280x720.  Is there a good free tool that will do all of these?  

Any help would be appreciated.

Thanks

You can download a FREE 30 trail version of Vegas Pro 11 from Sony.

I've have Vegas Pro 10 and I have used these features: Stabilize, Convert resolution down to 720p, and convert (render) to MP4.

I never convert resolution up, it just looks terrible (see my comments above).

By "Crop to Anamorphic", I am assuming you mean to convert 4:3 to 16:9, I have not tried this with Vegas as all my originals are already 16:9 HD. So you might want to google for that part.

If you go this route search YouTube for tutorials on each item as it will speed up your learning curve considerably.

Caution: if you want to take a 4:3 SD video and make it into a 720p 16:9 HD it's just gonna look terrible. Why? Because you are asking the software to expand the resolution, this never looks good. It's ok to reduce resolution say go from 1920 X 1080 and step it down to 720p, that's just fine, but when you try to go the other way you are asking the software to essentially make up material that is not there.
