Analog direct-to-disk uncompressed in a sports coaching sys
on Dec 24, 2006 at 2:34:17 pm

Goal:
Build an inexpensive video system that will allow capture of short clips and high quality frame-by-frame playback for use in coaching sports.

Idea 1:
Use a video cam with SVHS or component output and capture uncompressed direct-to-disk video. Then playback video including frame-by-frame analysis using the same software used to capture the video.
720x480pixels, 30fps, 3x8bits color,

NTSC data rate = 720x480x30x3x8 = about 250Mb/s with sound
A dedicated single modern hard drive can do this easily.

Efforts so far:
ATI Tv-Wonder, 'too slow to capture/save uncompressed.
I bought ATI All-in-Wonder 9600 to use as video capture board. It seems the AGP 8x slot will transmit data fast enough to the system and allows saving at uncompressed 720x480 30fps. I got pinnacle studio to do this but the program made a mess of my computer. (version 8 and 9) Windows movie Maker does not allow uncompressed capture.

Questions:

What software will allow me to capture 720x480 30fps uncompressed and allow frame-by-frame playback immediately after capture?

Is there an analog capture card that will do a better job than the ATI All-in-Wonder card?
