HD in what formats?

post #1 of 6
Thread Starter 
I apologize if this is in the wrong area, but, I wasn't really sure where else this might go. Although it is related to video cards.

I've got a quick format question for anyone who might know

I know that H.264 is probably the optimum format for viewing HD on your PC, but, is it the only format?

For example when you get a AVI file that says it's HD is it really the HD standard,or was it just converted from HD?

Can something be HD if it's in AVI or MPEG4 format?

AVI is a container for MPEG4. It is basically a bin for the video and audio.

HD all depends on bitrates and resolution. if the bitrate of an MPEG4 movie is higher than about 3000 and the resolution is 1280x720p or higher it will usually be pretty good quality.

Hope that helps...I don't explain things well.

While my upconvert DVD player makes AVI files look better, it is not even close to HD on my tv.

I understand so basically a video format just needs to meet these standards or higher to be HD. I didn't understand what you meant by AVI being a container for MPEG4.

H.264 isn't a format, it's a codec for video compression. Go here:

Look around and you should be able to find the info that you are looking for.
