View Full Version : H.264 file size?
Jul 17, 2005, 05:30 PM
I encoded a 1:35 clip in H.264 using quicktime pro and the file size is 274 MB. I shot it in minidv so it barely compressed it at all, and on top of that the quality looks like crap, what did i do wrong, the hd clips on the apple website which look perfect are half that size. these are the options i used:
24 keyframes per second
audio: linear pcm

Use 128Kbps AAC audio.
A high quality video setting creates large H.264 files, try using medium. It won't ever look as good as your original source, plus when you are using 24 keyframes, is your video interlaced?

I don't know actually, i thought minidv ntsc was 30 frames interlaced.

As Lacero said, ditch the linear PCM audio in your encode and use AAC instead.
For keyframes, leave that at "automatic." For framerate, use the original framerate (don't change it in the encode unless you're cutting it exactly in half).
Your video data rate can be set to maybe 1000 kbps. That in H.264 will probably look as good as the original file.
