I use a freeware program called
XMedia Recode for most of my audio and video encoding.
It's pretty powerfull.. you can choose between lots of codecs and change about every setting there is. Although I don't have a clue what most of the stuff means. So this might be a pro or con depending on what you want.
There are many nice features but I just want to mention something that I believe to be particularly useful:
You can create a queue of things to be encoded (every item can use different encoding settings). Since encoding can take quite some time it's a relief not to have to wait for every single task to be finished in order to start the next one. And one other thing: You can already do some rough cutting (set a start and end time) so you don't have to encode something you don't need. It's great for testing encoding settings on specific (challenging) scenes.
Regardless of the codec you use be sure to keep the original frame rate as well as the aspect ratio and if the source material are mpg files I think it's a good choice to activate some deinterlacing.
I recommend testing the different deinterlacing algorithms to see which one works best for you. I did some quick testing and only 'linear blending' got me a decent result, but the quality of the mpg file I used wasn't very good.
Scenes with fast movement (and maybe some contrast) are best to reveal there weaknesses, I think.
If you decide to try this program out I'd be happy to share the few things I know, so feel free to ask.
Edit: A new version (2.2.3.2) has been released. Link is updated.
Supported OS: Windows 2000 / XP / Vista / 7
