Would a TBC help quality in a VHS to DVD conversion?

[Fuct Victim]

I was finally able to copy my first VHS to DVD. Im a little disappointed in the quality though. The video isnt very sharp and there are a lot of horizontal lines. I read on lordsmurfs website about JVC VCRs with TBC, and I was wondering how many of you own these? Also will I notice a big improvement? Currently Im using a RCA 4head HiFi VCR hooked to a Winfast 2000 PVR Deluxe via co-ax then burning to DVD using MF2. Any suggestions that would help me increase the quality would be appreciated.

Thanks

I recently bought a JVC 9911u, which has the TBC/DNR. I have 2 capture cards, a Hauppauge PVR-250 for real-time, and AVI capturing Hauppauge card for tough tapes. I discovered that the JVC's TBC actually gives me some audio sync problems with the 250, although the video still looks considerably better.

Just yesterday, I made some test captures from an old 60's tv series recorded off of TV, that's a 2nd generation tape to start off with. The results with the TBC on and off were amazing! With the TCB on, the video was about 1000% better than with it off! Tearing was reduced to nothing in most scenes, and dropped video frames were as follows.

With TBC on, 42 dropped frames in the whole 1 hour and 22 minutes, and that includes the poor start of the tape, which dropped 10 frames as the recorder got up to speed, and 10 more frames on a MAJOR tape glitch where there was NO video for a little bit.

With TBC off, I only recorded 5 minutes, but the video was terrible, MUCH tearing, and frames dropped were over 200 at the 5 minute point. I ended the test at that point.

My computer is pretty slow, only a 750 mhz Athlon, so with more power, I might have had fewer frame drops, but the CPU was at like 50%, so I doubt the difference would be too great.

You say you're using coax. Why aren't you using Line-in?

I recently captured an ex-rental tape (so you can imagine the quality) using a Duron 1.3Gz and Pinnacle DC10+ capture card via composite video in. Using Pinnacle Studio 7, capturing at 720x576 (low compression) I got 80 drops over 2 hours which seemed okay to me. Many were at the start as the tape got up to speed - some during the middle when the tape was a bit flaky. Output file was 13G in size and I was capturing to a 80G drive (ATA/133 7200) which is also the boot drive

Thanks for your replys.

By line in do you mean composite? I tried using composite/CVBS but the quality appeared to be better with the coax.

I can tell you that with TBC and the 3DNR settings on JVC vcr's the quality of a tape can be GREATLY improved.. I have taken a tape that was recorded in SLP 6HR mode, about 10 years ago, and played it in the JVC and it looks like it was recorded yesterday in SP mode.

Yes.

And, I'd like to add, you don't have to hunt down a JVC to get excellent results. Now I'm not dissin' on JVC (the VCRs in question, particularly the slightly-older units, are top-notch) but I ran an external TBC with a Sony SLV-740HF (fair quality) and the output is quite pleasing.

You missed out 'does a one legged duck swim in a circle ?'

I saw a duck swimming in a circle once, that explains it.

You can't increase the quality using any kind of dvd authoring. I'm moving your topic.

[kupton]

It sounds like the "lines" you're talking about could be RF noise due to using coax.

[Ricardo]

I'm wondering if the lines are due to resizing an interlaced movie file without deinterlacing first.

This is easy to do if the capture device crops by default, or the capture size it different to output from your editing software output.
