My Computer can handle the original videos just fine. However if I want them on my website and not kill my bandwidth, I don't want them to to be over 100MB each. I'm trying to get them down to 20MB or under.
oh, so it's web video you are encoding... uploading the source video out of the camera won't help solve this problem, all you need is some encoder tweaking.
to give you an idea of the encoder settings to target... i encode flash at 960x540x30fps, 600kbps variable bitrate video, 112kbps stereo audio, two-pass encoding with squeeze 5.
