AMV size

How large is the aveerage AMV AVI file before it's compressed?

It probably varies depending how fanatical the person is and the format they are using. When I started out capturing MJPEG I did it at 2.3-3megs/sec which gave me about 600 megs per video. As I went on my standards changed, now the final render of my videos is typically 1.4-1.8 gigs. I've deicded that drive space is cheap but my time isn't ... so I don't want my master to have much if any loss due to compression.

Mine usually run around 1 to 1.5 GB.

Are those the ones that you finish?

1.6 gigs, I encode in Mpeg though so that reading is what my program predicts the file size to be. It's often only off by .05 gigs in either direction though.

Yes.

All of mine are always over 1 gig! Ranging from 1 to 1.6 gigs. (man.. I need more hard drive space... Goes out and buys another one...)

I capture at mjpeg at 6005kps a sec (604 x 464 Studio DC10+ settings) and I usually encode in either ligos or huffy. Ligos tends to give me 200mb avi files for something that's minute and a half long. Huffy is around 400-500mb and no compressor gives me a gig or 2.

With the type of compression and frame size I use a 4 minute long video would be about 1.2 gigs. Huffyuv in YUY2 mode, 640 x 480 @ 24 fps. Of course the source files for my last vid took up about 9 gigs (same formula) but quality always has priority over drive space.

Do you peole who use HuffYUV encode to RGB or use the convertYUY2 option?

I've found the YUY2 option paired with "best" compression gives reasonable data rates (generally a good bit smaller than RGB.) If my understanding of it all is correct it's still practically lossless in that it doesn't introduce any grain ... just a small amount of of color fading or shifting which isn't really noticable (this color loss is from the video being converted between color spaces.)
