Scrolling in Panasonic AG-8700 full frame TBC?
I'm converting my VHS, S-VHS and Hi8 tapes to digital (most are masters or 1st generation tapes recorded in high grade tapes with pro-consumer recorders). I started to use uniquely JVC HM-DR10000 and JVC HR-S9700 (PAL models) and Sony EVO-9850 (NTSC model) and a Canopus (Grass Valley) ADVC-300. I was using only the videos TBC (line TBC/DNR) instead Canopus TBC: so, the Canopus was only doing the analogue to digital conversion.
Today I tried to use my Panasonic AG-8700 full frame TBC (note: I don't use AG-8700 as a player because most of home tapes do not play so good in this pro model). Well, I discover AG-8700 full frame TBC is the best I have: generally better than JVC line TBC or Canopus TBC. E.g., JVC HM-DR1000 (player, TBC/DNR off) - full frame TBC on (Panasonic AG-8700) - Canopus ADVC-300 - PC. Unfortunately I've one problem: sometimes scroll happens (video available at https://youtu.be/PXpCiunLRn0). I've tried the AG-8700 TBC settings but no solution. So, do you think I could do some DIY? I've the service manuals but no serious technician skills. When I turn off Panasonic TBC the scrollings stop. So, I think the problem is related to the TBC cards (TBC1 or TBC2). Recommendations to repair this problem are welcome (DIY)! :-) Of course I'm trying to avoid to send AG-8700 to maintenance... probably it's some cards' setting. Like I'm trying the best conversion "possible", I'm also using high end cables: DPA Black Slink silver cables with WBT connectors (audio) and Nordost Optix Super S (s-video cable). By the way, the best video player I know is the JVC HM-DR10000 (D-VHS). It is something better than JVC HR-S9700: better colors. I always prefered JVC in JVC vs. Panasonic wars. Probably not all agree with my choice. Well, I need help!... |

Right now the AG8700 is defective, only the player AG8600 with over 100 new capacitors marches yet. Error in the Stream = I know, I did even if I. With the Canopus NX capture from AG8x00 Picture bounces by BFF and then by TFF. I only know the German name ... "Bildhüpfer" ="picture hops" Remedy here S-Video and Audio to Pana DMR EH595 [front] Output via HDMI ... or Pana DMR ES10 ... Output S-Video. A little hint: 1004 = 02 [unloading] 2007 = 01 = ON [V-Blanking select.] and Audio I only take from front headphone [6.3 mm] jack. Adjust level properly, do not forget. ------------ Quote:

It actually sounds like the Germans have a better term! Less confusing? :D |

I am not a German man, speak Swiss German and write in German ... As a true Swiss Switzerland Founded in 1291 Germany 1945 ------------------ possible would signal via YUV or S-Video provide the AG8700 for Datavideo DAC 7 and from there via SDI to a BM card with SDI in. Capture with VDub or the Blackmagic Software |

Today I watched carefully some DV conversions using Panasonic AG-8700 as a full frame TBC, and it is better than JVC video's line TBC when dealing with removing dropouts. So, it will not be a big problem of I can't use my AG-8700, since most of tapes doesn't jave a large number of dropouts (some with more than 20 years). I purchased AG-8700 only with 600 hours and close to mint condition/after full maintenance at about 6 years ago (I paid around Euro 600.00!). Anyway, I'll try your recommended settings. I never use headphone jack. When the outup is a balanced XLR I use a XLR to RCA adaptor. So, did you send your AG-8600 for the change of 100 capacitors? I remember when I played a couple of S-VHS tapes (master tapes, top grade) at about 6 years ago in AG-8700 (it was working perfect), I found it too much sensitive to dropouts. The JVC HM-DR10000 or JVC HR-S9700 picture quality is much, much better, so I didn't decide to use it as a player, despite in theory it should be the best. I'm recording my DV in uncompressed AVI files and keep those in blu-ray data disks. For my favorite recordings I also made some blu-ray video disks, a better option than DVD video disks. By the way, I know there are some big fans of Canopus ADVC-300 and some with opposite evaluations of it. It is a great analogue to digital converter, but using these JVC videos I don't need to use the Canopus TBC settings and I prefer JVC TBC results than Canopus TBC results, so, it is turned off. Canopus TBC most of time doesn't improve the quality taking a lot of definition. I'm using it with Windows 10 without problems (I'm also using in Windows 10 the Picture Controller 300).
Attached is a photo of my analogue to digital conversion system. I also have a Grundig GV-280 (Panasonic drum) recorder. It was a gift from my lovely grandparents when I was 18 years old (today I'm 43). It is still in mint condition. I remember it was extremely expensive. Well, the picture quality isn't so good as my JVCs decks, so it is there but unused. |

The Canopus ADVC-300 is actually lower quality the 50/55 or 100/110 models, and does not have a TBC. Canopus (now Grass Valley) claims it has a "TBC", but none of the positive effects can be seen/verified when testing it. The image is not improved, the signal quality is not improved. The JVC TBC is good, but is visual only. If does not effect the signal integrity. Generally, you need both an internal VCR TBC to "clean the image", and an external frame sync TBC to "clean the signal". Quote:

But the founding info is interesting. I guess before WWII, technically Germany was known as Prussia, though between WWI and WWII it had sort of an identity crisis (Weimar/Nazi era). And the name came about from it being a "Germanic" society. Having flashbacks to college history. :laugh: I actually never knew German speakers were in Switzerland. :o |

The AG-8700 TBC, if it's really working on passthrough (I'm still dubious), may be useful. Passthrough TBCs (TBCs in other gear) are nice to have around. But you could have a capacitor issue, and they need replacing. Or it just fails to work well in certain workflows, and you'll have to identify what those.
The ADVC-300 adds processing noise. It's not an opinion, it's fact. The idea behind the 300 was the typical "least worst" scenario, where restoring one aspect (or more) creates a different harmful side effect. But the new side effect is preferable to the last. That's acceptable in a restoration workflow, but not at the hardware capture level, which is why it's completely disliked, and almost universally panned as a failed device. The ADVC-100 had none of the processing noise, though it still suffers from DV colorspace loss. Note that PAL 4:2:0 is nowhere near as bad as NTSC 4:1:1. I'm not as against PAL DV as much as Goldwing is, but I'm still not a fan. Being in PAL, your choices are more limited. From my own use of the DataVdeio TBC-100 and TBC-1000, they work great with PAL. We just got in a TBC-3000, and I'll give that a battery of tests here this weekend. A DataVideo is probably your best bet. And thanks. :) |
