capturing uncompressed

[taz291819]

I'm using an ATI AIW 9700 Pro w/VirtualDub to capture some Directv. My settings are 44.1 audio, 29.97fps, 740x480. If I use the PIC MJPEG codec set at 20, I get no dropped frames and system resources around 35-40%. I can then play these back directly using zoom player and bsplayer just fine. But when I try to capture with the same settings, but UNCOMPRESSED, I still get no dropped frames and system resources around 20%. BUT, when I try to play the file back in zoom or bsplayer, the audio is fine, but the video plays like it is at about 20fps (kinda like time lapse recording). Is it supposed to do that? Do I need to encode the files before trying to play them back? I planning capturing a show tonight and want the best quality so I can encode it to dvd complaint mpeg-2 and burn it to dvd. The show is 90 min so I have enough HDD space. Any help would be appreciated. My specs:

P4 2.4Gz
512Mb DDR
120Gb HDD (80 and 40)
ATI AIW 9700 Pro

Because uncompressed AVI files are so huge, most players have a hard time dealing with playback and keeping up in reading it (mine does the same). It should play fine after encoding and reducing it's size.

Ditto! I can't use uncompressed because any of my post-processing software crashes. The files are at (or beyond) the limit of my harddrive subsystem to keep up. VDUB takes so long to seek, it's unuseable (I'm talking a 70 GB file here).

MJpeg(virtually lossless) at 20(or 19) is fine, or Huffyuv (lossless compression) works well.

tax291818,

I've been doing the same as you. Capturing to mjpeg or huffyuv with my ATI AIW Radeon from Dishnet with problems with sync or editting or something.

In the end I'm using MMC 8.1 with absolutely great results. Any older version of MMC and I couldn't say that. I'm capturing at (full D1?) MPEG2, 720x480, 29.97, 3500 avg x 6000 max (where's the min. setting?) with 192k mpg2 stereo and have never been happier with my captures.

I just recorded the Babylon 5 movies this weekend, 6 hrs of continous capture (didn't want to play with timing in between movies) with the above settings and ended up with a file at about 6.4 gig in complete sync. And I don't worry about opening up mail or running a p2p app, though I still shut them down when I think of it.

I opened the capture up in TMPGenc to cut the three movies into their own mpg files and then processed each of them to cut the commercials out. Each movie, after commercials, is about 1.2 gig. All three will now nicely fit onto one DVD-R. Use MF2 to pretty up some menus and chapters and I'm good to go.
