Could someone explain a few things to me?
Firstly, I am using Windows 7 64 bit on a 4gb machine, 3ghz dual core
processor. My video editor is Sony Vegas Platinum 9, and the
camcorder is a Flip HD machine, giving1280x720 mp4 files.
I've been experimenting with various formats for rendering, wanting
one uncompressed type for keeping a full quality archive of videos,
and one output type for use on YouTube. The latter I seem to have got
the hang of now, but I'm wondering about my uncompressed avi files.
Even on this pretty well-equipped machine on playback with Windows
Media Player or VLC the smoothness is flawed and the audio goes out of
sync. A 1 minute and 20 second file as rendered from Vegas takes up 6
gb, which seems a bit high... The RAM and the CPU aren't especially
taxed when I inspect the Performance tab of Task Manager.
I'd like to know what the difference is between a container and a
codec. How is it that a file can be avi and mp4, as sometimes seems
the case, for example some downloaded film files show this in their
Properties.
Thanks.
