some capture questions

i have vegas5+dvd and always use DV capture via firewire. i believe the AVI files are around 210MB per minute of captured video.

a friend of mine at work has some old analog video and has been trialing several different softwares to capture analog A/V. i told him about vegas movie studio + dvd and he downloaded the trail. he told me this morning that vegas movie studio captured his analog video just fine through his video card. is this something new to movie studio, or can vegas 5 also do this?

he said 5 minutes of captured AVI was around 6GB. that's quite a bit bigger than capturing DV. why is his captured video so much bigger than DV captured video? also, is there a way to reduce this during capture?

i told him he could probably take that huge AVI, put it into the vegas movie studio timeline, and render it to a NTSC DV AVI or MPEG2, which should reduce the size greatly. is this good advice, or is there a better solution? i would think movie studio would run better using a smaller file.

thanks for any help. he already seems convinced to buy movie studio. he just wants to be sure he can get the captured video to a reasonably file size.

Yes, Vegas can capture from a variety of devices. I have an ATI Rage Fury VIVO card at home with analog video I/O and Vegas captures through that just fine. I prefer to use an external A/V->DV converter as it's better quality though.

Your friend is probably capturing 640x480x164bit 29.97fps uncompressed avi files which are about 1.1GB/minute, or 24bit which are about 1.6GB/minute. Your advice to render these to DV .avi files is good. He'll end up with about 225MB/minute and MovieStudio will display, scroll, and render from this format much faster than from uncompressed .avi.
