HD Video compressing software

Hello,
I'm looking for a capable ultra software to edit any HD video format of exceptional quality. Are there any free alternatives so that I can upload it on youtube videos.

The process of compression actually throws away information from the file ... no compression is lossless. But some codecs are more efficient than others so it may still look good ... just not the same quality as the original.

If you want to create a DVD-Video, you'll need to choose whether you want an SD DVD or an HD-DVD. For a set-top compatible HD-DVD you will need an HD DVD burner and authoring program.

For an SD DVD, your video will need to be encoded as SD ... then you can decide whether or not you need a dual or single layer disc.

There are currently two major compressed HD video formats for consumers and prosumers widely available in a variety of cameras, from the very cheap to the relatively expensive. The first is HDV and the second, and newest, is AVCHD.

You should use Compressors frame controls to resize your video. Obviously, setting it to best quality resize will be the best method but it will take a very long time. You could set it to second best (Linear I think) and it will still do a great job and not take nearly as long.
