This unit also have issues with locked fields (similar to what's demonstrated here here) (though it's a bit visually different, as the AVT the field, while on the TVOne (not sure how to best describe it) rolls instead of being frozen still (I might be able to provide video if there is any interest). I haven't noticed any deteriorated image quality from it as reported in the linked thread, though I haven't done checks with test images, so it's possible that the image defects are present in this one as well. |
Correct. The 1T-TBC eventually also had the same problems as the AVT-8710/CTB-100. I've updated the post you've quoted with more updated/current accurate info.
The entire Cypress/AVT TBC ordeal ended quite sadly. No fix ever existed, simply a discontinued product. :( Since Cypress/AVT serial numbers reflect the date of manufacturer, so only get TBCs made before 2010 to be safe. The AVT-8710 is green, the rarer CTB-100 is Smurfy-blue on gray (not muted blue on silver). Unfortunately, the 1T-TBCs never changed it's look, so it's not as simply as color. Must find/read the serial. |
This might be nutty, but with all the gadgetry and 3D printers and electronic stuff, can someone with the correct knowledge actually build a TBC? Same for VCR parts, 3D printers? It's brave new world wizardry that might be applied to old world crappery?

I came across this the other day. It looks abandoned, but it suggests it's doable.

I came across another DIY TBC project here. This person is using the same A/D converter as the one in the AVT8710, with a slightly differend D/A chip and a different microcontroller. Interestingly he's using the 16-bit colour mode of the SAA7114H, while the AVT uses the 8-bit colour mode (from what I can tell at least). So it seems like it would indeed be possible to create something using off-the-shelf parts. |

Connecting VCR to projector
Hi there,
Sorry to resurrect this old thread. I'm a complete amateur and not interested in digitising VHS tapes, just projecting them through a digital projector. Unfortunately some of my tapes are in bad condition, and the projector plays the video for a bit but intermittently shows 'no signal'. Do you think a TBC could help me with this set-up? Thanks Max |

Try that first. |
Is TBC worth the money?
I want to convert old VHS tapes to digital format .mp4, it can cost me 7$ with these cheap hardware (easycap usb 2.0), or 300$+ with TBC. is it worth the money?

Acquiring quality hardware for quality transfer is almost always worthwhile. Why forever convert VHS to look terrible? If that's the case, why bother converting at all? A VHS tape can, and should, look better than the tape. Not worse. VHS has a lot of problems, most of which can be corrected with the right equipment. Or made worse with the wrong equipment. |

But it all depends on how good is good enough for you (and also how bad your tapes and other gear are). Read the posts in this and other threads and forums, view the before/after exampls in many of the threads, and form your own opinion as to what will meet your needs. It is, after all, your tapes, your time, your money, and if doing this for others your reputation. You can always try cheap, decide the results draw a vacuum, and then do it again the better way (provided the tapes have not been trashed by a bad VCR on the first try). |

It's not an optional item. :no2: Yes, there are some conditions where you can make passable capture/conversions without TBC, but it's not quality. There will be flaws. And again, some conditions, not all -- too many people think they're the exception, rather than the rule. Avoiding TBC is unlikely for most. TBCs is a necessarily evil, a costly item. Always was, always will be. I remember grumbling when I had to buy my first TBC in the 90s. Then I saw what a difference it made. I grumbled less. :laugh: |
Maybe I should have said; "How bad is good enough for you."

If a TBC is so necessary, then we should come up with a project for people to be able to build their own TBC. This thread lists a number of projects that do just that, and I know a number of people here are experienced in electronic design. Perhaps you could solicit some help from the people here? |

- Broadcast/rackmounts were $1k+ (not desirable anyway). - A few studio-grade TBCs (from same makers as the broadcast) were in the $500-$1k range. - The prosumer were almost all in the $450-750 range. - The one exception was the Taiwanese maker Cypress, which had some sub-$400 prosumer units. Unfortunately, in an apparent effort to keep costs down low, actually reducing price over time (negative inflation), flawed chipsets were used, making the unit useless. - Note that Cypress also had studio-grade units in the $500-$1k range. The idea that a homemade TBC could be made cheaper than a mass produced unit, and be of equal quality, is flawed. And here's an example of why... Most folks here don't know that my other hobby is action figures (which should make sense once they realize the reason I got into video was due to cartoon collecting). Not just action figures, but customizing figures. That takes a lot of time, and generally costs 10x+ as a mass produced figure. Yet the newbie misconception is that a custom figure should cost the same as the mass produced figure. So what happens is you'll find people on forums/Facebook whining about customizers "charging too much" when in reality they generally break even, and do it mostly as 1st-run practice for the custom kept for their own collection. Another issue with TBCs is that it's not just about electronics know-how, but availability of parts. Realize that DataVideo and Cypress both left the TBC market specifically because the needed chips were discontinued. So that's a major problem preventing future TBC production. There was a small window, years ago, when new TBCs were still available (though mostly EOL and NOS only), and used TBCs sold for the standard 50-75% new value. So, for example, you could get a TBC-1000 for $300 or so. But that didn't last, and was never going to last. It also coincided somewhat with the recession and post-recession market (2009, early 2010s), where there is a fire sale type of mentality (sell for whatever you can get, need cash now), combined with less buyers. The biggest problem with buying a TBC is user mentality. Understand that it's probably not a "forever purchase" for most people. You don't buy it, use it, and then stick it in a box in the closet. It's a "project purchase". Buy it, use it, resell it. In the end, it's essentially a rental. You'll get most, or even all, of your money back on it. |
It depends on where you live. It’s really hard to find any where I live.

So are rackmounts like the JVC SA-T100 no good? I.DEN IVT-7 ?
I'm assuming Fortel Y-688 is useless. |
