    I am the owner of a large collection of VHS cassettes (over 200 pieces) pre-recorded with popular science films, protected by macrovision. I intend to start a project of transferring them to the DVD format, using equipment collected for a few years for this purpose. Please experienced specialists in digital video refreshing for advice and suggestions on how to best connect and use existing ones devices to remove macrovision, FOTA etc. and achieving the best possible quality. I also ask for a proven script avisynth for later editing.

    - SVHS - Panasonic NV-FS200 - TBC
    - KeyWest - Big Voodoo TBC-10
    - Panasonic ES-10
    - PC - i7 + 32 Gb RAM + 4x HDD = 24 Tb + Blackmagic Intensity Pro - pci-x

    I also have several different proc-amp composite processors, s-video, brightness, hue, etc ... ex: Sansui AV-77

    You are having trouble with Macrovision even with a Big Voodoo TBC-10? Anyway I would suggest getting a capture card that simply ignores macrovision completely. It's also generally not as good to transfer directly to DVD from VHS.

  3. Use Canopus ADVC-100, it defeats macrovision from VHS and DVD no problem. I also have in my backups a japanese schematic of a circuit that does just that too.

    Again, @amaipaipai, only SOME, early models of ADVC-100 defeat Macrovision. It is well-known that Canopus was leaned on by Macrovision to enforce their copy protection, so they had to close that loophole in later versions of that and in subsequent models.
    That makes the option to use those models for that purpose much more of a crap shoot.

  5. The early models works on the spot (the one I have), others ones does the same by holding input/select button. From what I hear, this works up to ADVC-300 but I don't have this model.

    I had an ADVC110 from 2009 that would defeat Macrovision by using the undocumented input/select button trick. The AVT-8710 frame sync does it as well.

  7. Of the 'one way' Canopus converters (i.e. no digital to analogue option), the ADVC50 can defeat Macrovision by selecting the appropriate jumper link combination.
    I don't think the later ADVC55 model has that option....

    VCR (TBC off) >
    ES10 (NR off) > ... and ONLY used when needed!
    external TBC (Big Voodoo = a really crappy TBC) >
    capture card (DV fine for PAL 4:2:0, lousy 4:1:1 for NTSC)

    You don't want the TBCs to conflict, it must be that order.

    Canopus didn't "defeat" anything, just ignored the flag. But it could, and would, still get tripped up by the artificial timing errors from MV. So TBC still needed.

    Hi. I apologize for the absence. Lordsmurf why do you suggest disabling TBC in S-VHS player ?? and only using ES10 ??. Was Big Voodoo so bad? Apparently ES10 does not have the full functionality of TBC ??. Do you know where there is any description of ES10 usage in the function as passthrough ??. I probably do not buy DataVideo, too expensive for me. But I still have a CDM-640 Multisystem Converter and it supposedly has a built-in TBC. Does anyone know this equipment ??.

    It can be hard to tell what is really a TBC, since the term is thrown around by so many manufacturers. Most outboard devices are actually frame synchronizers and may or may not do a good job on horizontal timing. The ES-10 and -15 have better correction than most; it's clear that Panasonic understood its market would be severely curtailed if customers got crummy transfers of their tapes.

    The earliest TBCs had only enough memory for a few lines of video, which was sufficient because pro machines did not have trouble with vertical stability. The old TBCs had a control line running back to the VTR and actually steered the motor to iron out timing problems.

    It's not a suggestion, but a requirement. If the VCR TBC is on, the ES10 will have zero effect. The first line TBC in the workflow is used, subsequent are not. Line TBC is not the same as external framesync TBC.

    Was Big Voodoo so bad?
    A horrible TBC.

    Apparently ES10 does not have the full functionality of TBC ??.
    Not as an external unit, not by itself. It's TBC(ish) at best, ideal when used with other devices (DVK-100). With full external TBC, only ES10/15 use is for anti-tearing.

    But I still have a CDM-640 Multisystem Converter and it supposedly has a built-in TBC. Does anyone know this equipment ??.
    Standard converters rarely have TBC engaged when not standards converting the signal. So PAL>PAL and NTSC>NTSC has no TBC, but PAL>NTSC and NTSC>PAL do. This isn't a unit I've tested to date, so unknown. I do know that the CDM-630 acted that way, only engaging TBC on standards conversion.

    Now I understand. Thank you all for advice and knowledge. So I'll try the configuration: VCR (TBC off) => ES10 (NR off) => TBC (Big Voodoo) => capture card, and another: VCR (TBC off) => ES10 (NR off) => TBC (CDM-640) => capture card. However, in the CDM-640 manual it says: "" TBC is active constantly, even in the bypass mode "", then it may be possible to assess which of my TBC will show a better result. Maybe in the near future I will be able to buy one of the suggested TBC DataVideo brands, but I know that it is difficult at a reasonable price ...

  13. I almost forgot about this thread, this is the Macrovision killer schematic. It was so good at the time that this kit was forbidden in Japan at the time because somebody were using it to make perfect copy's of DVD's at the time.
    This circuit works like a charm, all you have to do it's to find some one with an electronic skill to build a board for you, it has a trim pot for time adjustments so it can defeat almost any macrovision protection.



    To make this work with S-Video you need to feed this circuit with the Y signal and jump the input/output C signal.

    Or just use a capture card that ignores Macrovision.

    I can only speak from my experience. I had a U-matic deck with a worn capstan bearing that produced a small case of the wiggles on every playback. The ES15 straightened it out completely.

    Panasonic DMR E35S in progressive mode over the component video output defeats Macrovision, no external TBC needed for capturing. you do need a capture device with component video input, or a device that will do that in between, my Canopus ADVC100 worked also for defeating Macrovision, but they say that you loose some of the color spectrum that way, depends if this important or not for you, But new the ADVC100 was quiet expensive in my days, with what i know now, i have regret that i bought it ....
    btw in the "gamers world" there are also devices used to convert video signals from game consoles, also an open source project, i can't remember the name of, but i guess it is also something to look into since they also record "gameplay"

    well.... it's for NTSC, would it also work for PAL ? PAL was the analog standard, before DVB-T in Poland.
    (and even DVB-T settop boxes would convert to PAL is my guess)

    According to the datasheet it say it works with PAL.

    Only other thing with this cirquit is that you have to adjust 2 trimpotmeters, i hope you have to set these once. The NJM2246 is a little bit hard to find, Alieexpress is out of stock... maybe the 4066 is an option since it switches two video signals...

  20. One of the adjustments set the timings to kill different macrovision revisions, in general you set it once.
    About the NJM2246, this component is not produced anymore for a long time.

    I rather use a 4053 + opamp for video with a 6 dB gain, it's also important to bypass the 4053 switches.
