Is a TBC the solution to my woes?
I've slowly been picking up the hobby of transferring tapes. I've probably done around 300 tapes now, of various formats, and have experienced a handful of challenges.
I don't have the perfect set-up, but am dialing it in as I go along. I'm working to find a good balance between cost and effectiveness. I do have nice player - the JVC HR-S7800U in pristine condition. I'm using a capture card that isn't unanimously loved - the ADVC110. Importing with Final Cut Pro X on my Macbook Pro, but I don't expect that have any influence on my issue. I've messed around with running the 7800U through a Videonics MX-1. In some circumstances it does help. It seems to rarely fix footage, although it at least provides one stable long digital file rather than 100 broke clips. Rather than providing a clean unbroken video, it still has dropped frames but replaces them with glitchy hectic scattered screens wherever the time code is really bad. And on top of this, in the process of trying to resolve the time base errors, often the top 30 pixels or so of the video will glitch and periodically shift to the right. I'm eventually prepared to splurge on a Datavideo TBC-1000, if this is the answer to my problems. However, I'm hesitant before seeking professional advice. Will getting a TBC-1000 fix my problems? Will it give me one solid digital file when imported into my computer, without all sorts of dropped frames or crazy glitching? Will I be able to run VHS-C and other formats through it with the same effect? I'm truly trying to learn the craft, and would appreciate kind and helpful answers. Please be nice to a newbie like me. I'm aware that many of you prefer PC using Virtualdub, and also prefer other built-in capture cards rather than the Canopus. |

But there's also trade-offs. - When you cut corners on the capture card, the TBCs and VCRs become even more important for NOT cutting corners. - Cutting corners on VCR requires specifics on TBC(ish) and capture cards. - Cutting corners on TBC requires certain quality from VCR and capture card.

For Mac, depending on OS version, DV may be the only feasible workflow. What OS do you have? Quote:

Frames dropped over a Firewire transfer ? , never had dropped frames in my time with the ADVC100. (66/100MHz CPU)
There isnt much software that supports Firewire on MAC as far as i know, i've tried that, waste of (my) time. On MAC a semi pro capture card/device is a better choice, otherwise downgrading to old (Intel) windows OS's would be a better choice. Lordsmurf asked this already: which version MAC and OS you are using ? System wise there are a lot of differences on "a" MAC, 32bit or 64bit version of the OS and the year "make" of the MAC hardware will give you different interface options, plus not all MAC software is available for 64bit in different situations it's better to have the one or the other.... A MAC desktop will give you the option to place a PCI capture in it in some "cases".... the MAC laptops have different Thunderbold version interfaces 2,3, and USB-C which don't mix with each other. |

ADVC cards can, and do, drop frames like any other capture card. Because it is just another capture card. And when fed untimed (ie lack of TBC) input, it chokes, it drop frames. |

The ADVC110 needs bus power is see now... or a separate power adapter, when no bus power is available, otherwise it should be no problem to "capture" video with it, the JVC HR-S7800U has even build in TBC of some sort ? it has a lot of picture adjustment options... maybe there's some improvement to gain there... trying different options.. Tapes with slow recording speed, will always be a problem... |
The Canopus and Edirol firewire capture devices are built in frame synchronizers, If you choose lock audio function it's impossible to loose audio sync. However they are still DV capture devices and have their drawbacks, on top of that DV is ancient now and most likely the capture will end up having another conversion to H.264, So may as well capture lossless and encode to anything the current playback hardware requires.

Yes, i did set the audio-lock in those days, but never experienced the problems the OP mentioned,
I did used window$ at that time, only other trapdoor was type 1 or 2 audio i remember. and having very large files..... i'm happy now with my Intensity Shuttle using ProRes422LT |

This is not what "audio lock" does. It does not refer to audio+video sync. Nor is it created for any analog sources. This is pure marketing nonsense from Canopus. In addition, "audio lock" is a feature specifically reserved for pro DV25, not consumer DV25 (of which the Canopus uses). The "audio lock" feature is only for timecodes. This myth has been repeated for 20+ years now, and I have to correct it constantly. You've fallen for Canopus marketing. Don't feel bad, we all have, at some point. BTW, that Canopus is long gone now, and "Canopus" is just a brand owned by another company (Grass Valley). Yet the BS of yesterday simply will not fade into the scrap heap of misinformation as it should, and gets repeated far too often, decades later. Quote:
