Video encoders

[DeNeDe17]

anyone knows with which programs i can encod simple .avi into .avi with HD standards !?
i've saw a video and then the same video in HD and it was awsome ..
but the video in HD was smaller that the original one
if someone has the time to help me understand this stuff would be great .
thankyou

I think can you do it with Nero Vision if your trying to make a dvd out of the video.

Dr.Divx will produce in 1080hd.

Remember that the output file even if done in 1080 or other hd settings is limited in quality by the original input file

depends on the source as well.
