Thanked 1 Time in 1 Post
First off, this is a great service you offer and a wonderful site, so thanks. Hope you can help me out. Iím relatively new to getting serious about vhs to dvd conversion. Iíve been reading posts on vcdhelp.com for about a year waiting for prices to drop a little bit before getting into this hobby Ė so Iím ready to go!

I am working on converting some family videos taken around the mid-80s to the present and putting them through my AIW Radeon card (purchased about 4 years ago) and creating the best quality dvd I can. Iím pleased with my results when I watch the video on my dvd player until I put in the vhs tape and look at the original tape. The edges seem so much cleaner and crisper on the original and the picture clarity is good. The dvd picture on the other hand seems pixilated around the edges. I can definitely tell a difference between the two pictures. I compare it to the difference between scanning in a picture and comparing it to one taken from a nice digital camera. The image is crisper on the digital picture much like the image produced by the vhs while the scanned pictureís clarity isnít all there.

So, could you give me some suggestions? Do I need to change my settings? Am I working with low quality hardware (old AIW card, non-svhs)? Iím willing to upgrade if I can reproduce the vhsís image. Are my expectations too high? Let me know if you need any other infoÖthanks!

Settings in MMC that meet my liking:
MPEG-2 DVD
720 x 480 (Iíve tried 352 x 480Öit might just be me, but it seems like 720 looks a little better)
Encode Interlaced
P frames 2B frames 2 - GOP
VBR Max 4.0 MB/secTarget 3.90 MB/sec Estimation 98
Sharpen 28%

Asus A7V8X motherboard with Athlon XP 2600 processor
512 MB RAM (2700 DDR)
ATI All in Wonder Radeon
NEC 2500 DVD Burner with Nero 9
80 GB Hard Drive (I know, Iíll need a larger one)
Windows 2000 SP4, Direct X 9, MMC 9.0
Sharp VC-H914 Hi-Fi VCR with gold composite cables from Radio Shack
Toshiba SD-3750 DVD player

Well, I wouldn't sharpen. That'll just bring out noise. Maybe 15% at max if you insist.

Also, check out the capture guides at digitalFAQ.com, the top 4-5 guides that covers the theory and not how to use software.

For 720x480 (which will be overkill for VHS source), use closer to 7.0-9.0 bitrate. For 352x480 use 3.5-5.0 bitrate.

Your setup looks quite good. Nero 6 I think, not 9. And then the AMD would normally concern me, but if the hardware all works, then it's fine. The capture card, VCR and DVD player are all quite nice choices, thing I have too (though models somewhat different).

The pixellation is most definitely a result of inadequte bitrate. I made out a bitrate curve chart (look near bottom of page for images) on this forum in the past few weeks. I'm adding a more complex version to the site guides, but the update is still lcoal on my PC, waiting until it's done before full upload (end of this week I hope).

I see that you use MMC 9.0. Did you upgrade from the ATI site? Did you have any install problems? My ATI AIW 8500 Radeon card came with MMC 7.6 and I am having problems trying to update.

I would still jump onto 8.7 ... I use 8.7 and 8.9.

Installing 8.9 was an adventure nobody should have.
