I'm using AIW Radeon 32M DDR. My CPU is AMD [email protected] 512M DDR, HD is 7200RPM. I'm using MMC 7.5, I set recording quality to best (DVD 720*480 30fps 8Mbits), It never lost any frame if I don't run any other application when I'm recording. 7 mins record file is around 400M, but that's ok, if you have 20-40G space left. It's enough for recording 2 hours movie. Then you can encode it to divx3.11 SBC, the final bitrate can be controlled around 1000K to 1500Kbps, so that the final file size will be around 700M for 1 hour movie. I never used any other TV-in card, so I don't know how it is compared to others, but the interesting thing is the processed file actually looks better than the original file because u can use deinterlace and bilininar (maybe spell this one wrong).


Could you provide some small video clips made by AIW?
I would like to check how good it is by myself....
Thanks.

Sorry I don't have a big web space, I can only put a small clip.

http://publish.shaw.ca/kirin/demo1.avi

It's a 18 seconds clip of 8.5M file.

I recorded it at best quality (720*480 30fps 8Mbps) in MMC 7.5, then encoded it to 656*480 divx 3.11 2pass SBC 1800Kbps for video and lame abr 128Kbps for audio.

With this quality, one 700M CD can hold around 25 minutes video, and if u low the bitrate a little bit, u can keep the same quality but store 50minues video on one CD.

I only can upload this much because the webspace limit is at 10M. If you have a big space, I can upload more

專業MPEG2壓縮卡一萬多買不到吧!
最便宜的Optibase Movie Maker 200 Basic FD1中古品也還要US$2000左右
一般專業壓縮卡多在數十萬~數百萬之間
