Captured File Size...

[trouby]

Hey Guys,

I tried to do some video capturing from my Sony digital camera for the first time.

I used Unlead Media studio for that,
I ran the Video Capture and did some video capturing of about 39.12 seconds, as a result I have an AVI file that takes about 143MB!

Is that normal!? I mean, if I want to transfer a full DV cassete of about 1.5Hours, will it take about 20GB?!

Even after encoding to MPEG2/DIVX I guess it won't take less than 5GB...

Is this the normal size? or I've missed something?

Thanks a lot.

This is normal, DV takes about 3.6 megabytes per second.

Yes, indeed. DV is compressed 5:1, which is not much compared to other video formats like MPEG-2 or MPEG-4.

It depends on the bitrate you choose. MPEG-2 need up to ten times more bitrate for the same quality as MPEG-4, but you can squeeze both formats on a single CD-R, if you are satisfied with the quality (you probably won't, not even for MPEG-4).

For good results I'd rather use 2 CDs for MPEG-4 (video bitrate around 2000 kbps), or a DVD-R for MPEG-2 (average bitrate above 4000 kbps).
