Is this the correct way to convert an .avi file from 4:3 to 16:9, using VirtualDub, or is there a better way?

Is it possible to use VirtutalDub and the resizing filter to convert a 4:3-AVI file to a 16:9-AVI file without cropping?--forum.videohelp.com

Upon seeing this question, I decided to download the free VirtualDub software, hoping to check out if it really works in knowledge of change aspect ratio. It turned out that it was OK to convert AVI video from 4:3 to 16:9. But soon afterwards, I found that there was a drawback of the VirtualDub--is mainly geared toward processing AVI files. That means, if you have got the videos in other format such as MP4, MOV, FLV and would like to change aspect ratio like from 4:3 to 16:9, you are shit-out-a-luck. Besides, VirtualDub is a Windows-based freeware without Mac version. What if you happen to be a Mac user, any other way to achieve your goal? I am telling you--yes!

Additionally, there are also bunches of great editing features, allowing you to make the best use of.
