Panasonic VCR vs. JVC VCR + my capture rig?
Hi,
I am new to this but have put together the below set of resources for my use: VCRs - Panasonic AG-1980P, JVC HR-S9900U, HR-S8000U, HR-S4600U, Sanyo VWM-800, Philips VR-6785 TBCs - TVOne Task 1T-TBC-GL, I.DEN I7-IVT Scaler - Extron DVS 204 Capture Cards - StarTech PEXHDCAP, Roxio Video Capture USB, WinTV-HVR 950Q I have not yet received the TVOne but love the enhanced output provided by the I.DEN. Problem is that the I.Den is very old and I can't find a service manual for it to make the right adjustments. Somebody has already fiddled with the internal adjustments along with the ones behind the front cover. Also there has to be some bad caps in it because there is this odd rolling light line that rolls from right to left. So we will wait for our TVOne and sell the I.Den for parts/as-is. Anyway, I couldn't find a 1980P to S9900U video comparison so I made one. I was disappointed with the JVC after having heard Lord Smurf compliment it so many times. I am afraid maybe mine is in disrepair or just has really worn heads. The capture rig was this: VCR -> S-Video -> Extron DVS 204 -> StarTech PEXHDCap Both VCRs had their TBCs enabled, the Extron had enhanced mode off and was set to 480P output. I feel the 1980P has a better picture for this particular setup. The left channel audio is the Panasonic and right channel is the JVC. https://www.youtube.com/watch?v=CMz_...ature=youtu.be Thanks, Chris |
Sorry, but we're not responsible for anything YouTube does to your videos. An accurate evaluation requires a cut from your original capture, not something that's been deintelaced, resized, re-encoded, etc, etc., etc.

But you are correct: Youtube butchers videos, so it's mostly useless for the purpose of samples. Always attach files to the forum (100mb max). @chjmartin2 I'm downloading your clip, and I'll look at it in a bit. However, anything over 100mb is honestly unneeded. I did glance at the Youtube clip. What I see is actually a problem with the Panasonic -- the picture is too dark and muddy. There is a magenta luma cast as well. The JVC may have a slight IRE issue, but it's very minimal. Some of that may be due to anti-copy, if this was a retail tape. Even when removed, anti-copy can have some lasting harmful side effects on analog video. Realize that my monitor is color/gamma calibrated for video work -- is yours? While you seem to have some nice video hardware (VCR, TBC), but I already see some weak links in your chain. For example, Roxio (anything they make) is crap. I'm not 100% sure about some of the other equipment; example: Extron. Never rule out those devices as being a problem, so always be sure to test VCRs with known-good TBCs, known-good capture cards, and nothing else in the chain. For upscaling, the AG-1980P may be better, yes. The JVC 9900 is excellent. If either give problems, then servicing may be required. Update: After download, the JVC shows more high-frequency noise -- but it's either from EDIT mode (no filtering), or the fact that the muddiness from the Panasonic is hiding it, or both. In terms of detail, I see almost no difference. The Panasonic is way too dark (likely capacitors are bad), and the JVC has an IRE issue. However, the IRE may be caused by upstream TBCs or other devices, meaning the Panasonic is even darker still when the correct IRE is output. |

IRE = black level. This isn't the same as gamma or contrast.

There is a way to make such a demo as lossless huffyuv or Lagarith in Avisynth without re-encoding, resizing, deinterlacing, or whatnot. :wink2: |
