Well, to be honest, I haven't tried posting on YouTube, yet. I've always had problems with email and video file size, so I was wanting to figure out how to reduce them before taking the next step.
But, for example, I have a 5 second long video, bit rate: 64 kbps, dimensions: 320x240, size: 1.51MB.
I guess that's plenty small enough for YouTube if you're doing 150MB vids.
Would a dedicated video recorder be better for taking vids or are the file sizes and length available going to be similar to what I have with my digital still camera?
