Do I Need a Time Base Corrector? (PVR-350 Problem)
I've been trying to capture some home movie VHS tapes with the PVR 350 and the result shows the occasional dropped frame which is really noticable. I think it's dropped frames. The sound is continuous while the picture jumps/jerks occasionally. The glitch doesn't seem to effect the a/v sync.
I've been doing a bit of reading and i've learnt that when old VHS tapes get so worn, the sync signal gets messed up causing these problems. One way to solve it, apparently, is to copy the worn tape to a new one and capture from that. The other way is to use a time base corrector. Could worn tapes be the cause of my problems and would a time base corrector really fix it for sure? I'm using Sage Recorder to capture. 3.06GHz HT Processer C-Media AC97 onboard Soundcard 1Gb Ram Nvidia Geforce FX 5200 160Gb HDD Partitioned Thanks in advance for any help! |

You'll loose a generation of quality in the copy, and the result will be worse! Quote:

I think there are some JVC SVHS VCRs that have a buit-in TBC. Problably not as good as a standalone TBC, but it's practical and not so expensive.
|
TBC works only in SVHS mode, not in VHS. So the source must be recorded in SVHS.
|
Nope, TBC does work for both VHS and SVHS. I've got a friend who has one of those JVC units GFR mentioned. In fact, they are better than standalone TBCs because the signal comes directly from the tape!
|
I had a JVC SVHS camcorder and the TBC works only on S-VHS recording (either on VHS or S-VHS tape, as this unit allowed to use VHS tapes even for SVHS recording). So I guess it depends on them.
Nevertheless, one thing is sure : the timecode is put at the recording time, and only by units that manage it. Chances are poor than rab's ones have it. |

Lol. You are talking about 2 kinds of TBC :
1/ standalone TBC, that are based on what wikipedia describes : Quote:
http://en.wikipedia.org/wiki/Linear_timecode As you said,#1 are less efficient than #2 (but can be used with any tapes). |
Funny, the friend I mentioned processed two tapes for me, both were shot on a regular VHS tape with a mono camcorder.. but maybe the device still recorded the timecode. The camcorder was bought something like 13-15 years ago. The difference between a normal capture and a TBC'd capture was huge so it can't be just a better VHS unit being used :?
