Big Voodoo TBC10 functionality, deinterlacing?
1 Attachment(s)
Hey folks,
I'm finally getting around to all of the hardware/software setup involved in capturing my VHS tapes and am now successfully capturing video in VirtualDub (essentially everything THIS guide recommends with the exception of using YUY2 over Huffyuv since my editing software (Sony Vegas 13) isn't playing friendly with Huffyuv). So to my questions: 1) Ensuring the TBC is working - The TBC I'm using is a Big Voodoo TBC10 (a.k.a. BV10). It's pictured HERE. If I'm getting video out of it, can I safely assume it is doing its job? Or, do TBCs sometimes default to passthrough and have to be enabled somehow to perform their function? I'm pretty sure it's doing what it should do seeing as how the video is better-centered and slightly less dingy (looks a bit more vibrant), but before I embark on a very lengthy journey, I just wanted to ask the "dumb question". 2) De-interlacing - I noticed the capture guide didn't say anything about de-interlacing. Do folks typically capture interlaced, then deinterlace in editing software after the fact? I just want to do whatever produces the best result. 3) Visual Artifacts - Can you take a look at the attached image and tell me if the "jitter" in the vertical lines of this footage is normal? It looks like a de-interlacing issue, but maybe it's just the way this tape is. Just trying to determine what to expect or if there's any change I should make in my process. Thank you! |

Smurf has long been talking about writing up a TBC guide (testing, repair, etc). Still waiting for that one. Quote:

Thanks for your response! It's probably worth mentioning that this is an "A-" kit that LordSmurf sold me, so at the very least it should be in good working order, but I recognize settings might need to be revisited once the items are powered on, so I'd love any advice you can offer. The VCR is a JVC SR-MV45U, by the way.
I'm afraid I don't have any known jittery tapes or any other additional equipment to test the hardware with, just this one "test tape" that I don't care about that I've been using to make sure the system works, and the rest are family videos that I'd only like to run through once. I've attached a couple of 2-second clips. I don't know how to trim clips without re-rendering since avidemux failed to split the files I'm capturing. So, it's not the exact same 2 seconds, but there is enough of an overlap to compare them in editing software if you want to do a 1:1 comparison between the frames of each clip. Appreciate any and all help! |

But not this exact version of this model. (Note that some BV units do reset themselves, just not yours.) Quote:

Hey Smurf, thanks for all of the info! Do you happen to have a PDF of the BV10 manual? Maybe we talked about it ages ago, but I only have the JVC manual.

I see folks discussing using ffdshow as a possible solution HERE. Just as an FYI of what I've done already, I've followed these instructions, which allowed me to successfully encode to Huffyuv in VirtualDub, but still can't edit in Vegas despite having the 64-bit version installed: Quote:
Really, my only goal is to capture these tapes in the best quality possible, de-interlace it all, chop it into clips, save those, then transcode them for viewing by my family. So, here's the rough workflow I'd like to do: 1) Capture in VirtualDub encoding in Huffyuv 2) QTGMC deinterlace later in Hybrid or Avisynth as you recommended 3) Chop into clips without having to re-render (Recommended apps to do this?) 4) Archive the clips on my backup drives so the originals are safe. 5) Make copies encoded to x264 using handbrake so my family can view them without having to have terabytes of storage. |
Since this is the goal, "my only goal is to capture these tapes in the best quality possible, de-interlace it all, chop it into clips, save those, then transcode them for viewing by my family" then do this:
step 1 - Capture, VirtualDub 1.9.x, Huffyuv 2 - Open in VirtualDub, chop clips, stream copy output (aka no encode) 3 - Open in Hybrid, choose Vapoursynth for deinterlace Save masters as clipped up Huffyuv for later, just in case. Don't trash master files. Save copies as clipped up deinterlaced H.264 also. For different project, I'd suggest different. For this exact project, this exact software workflow. All freeware, too! |

Big VooDoo BVTBC8/10 attached herein.
It should probably be added to the Manuals Index on this site. BW PS: Could this be the thread LS is referring to re: 32 bit vs 64 bit issues? PPS: When searching this forum, ignore the "Advanced Forum Search" option. Use the Google Custom search. It's far more effective. |

1) If you're running Windows 7 x64 like me, the latest version will throw an error. According to the creator's download page, the latest version you can use with Win7 x64 is 2020.12.13.1 2) When I tried to encode to x264 with passthrough audio to an avi container, only the audio was output. I had to change to an MKV container to get any video output. Do you have any recommended settings for the QTGMC (Vapoursynth) configuration? Seems like general consensus from some searches is that anything beyond "Slower" just isn't worth it. Also, do I do Even, Odd, or Bob? Any other settings like "Overwrite input scan type" or the percentage that is worth changing? If the answer to any of these questions is "it depends" then any guidance to help me make the necessary determinations is much appreciated. Quality is the priority. Screenshot attached for convenience. Even as a data engineer by trade, I find the number of options with this software a bit overwhelming! :eek: Quote:

Slower = softer
Use Faster. If you run into aliasing issues, sometimes Medium is needed, still not Slower. Bob converts to 59.94fps (59.94p) from the 29.97fps (59.94i) source. This can cause problems with home camcorder source. The fields can vibrate, and anything with an on-screen date will look terrible. Be careful with this setting, regardless of advice you see online insisting that you should always/only extra the fields to frames. It's just not accurate. Interpolation is always involved, aka fake data is created from neighbor fields. There is no "true" source here, in terms of the interlace fields and the outputs frame count. Odd/Even rarely makes a different, but all is 29.97fps output. In general, this is fine. You can auto-pilot this a bit more, not have to crawl all over the footage trying to find if artifacts were created from the deinterlace. Always overwrite the input as TFF. Assume the software is stupid (and with AVI source, it usually always is). Too many programs default to BFF, which is DV. It should be reversed, DV never default. Never encode H.264 in AVI wrapper, only MP4 or MKV. And MKV is better, it just will not stream on a webpage. But it does stream on LANs just fine. "it depends" -- reminds me of Beavis & Butthead. Hands lady box of Depends. "Uh, here you go, you poop in them." :laugh: I have encodes tips. For starters, encode 422 (4:2:2), don't degrade colorspace to 420. That is set in two places. I replied to a post some time back, which gave the encode settings I suggested. Not defaults. I can screen can those again if needed, but not at that computer today. Vegas is a great editor, but the wrong tool here, not needed. |

Thanks again. I definitely want to dig more into optimal Hybrid settings later on, but after giving it some thought I think I'm ready to begin capturing.
Regarding VirtualDub, I've confirmed all of the settings are correct using the capture guide and that it's capturing in 4:2:2 (Screenshot 1). I also did a 1-hour test with a test tape and the setup was rock solid with 0 frame drops (Screenshot 2). Looks like huffyuv files end up being about 30GB per hour of footage, so I suspect this project is going to suck up most of my media server's remaining space. In fact, I'm starting to question if I'll have enough space... I have like Is there anything else I should double-check before I begin capturing tapes in earnest? I also sat down and did some number-crunching and... it was sobering. I have 110 tapes... spread across a variety of types. Given the ~30GB/hour of footage I got with huffyuv, it's looking like I'd need 5.26TB in the best case and 14.47TB in the worst case, depending on recording speed (Screenshot 3). Do you have any thoughts regarding space efficiency? Dropping 1-2K on a redundant array would be a gut punch I don't need right now, so what I might do for this is just drop a few hundred on a 16TB drive and just save the masters on that with the intention of keeping it unplugged in long-term storage. |
We need to verify your timing settings, in capture settings. Screen cap that, attach.
These days, I also tend to disable DirectX in the main settings. It never helps (exception = AIW), but can screw stuff up. So at best, for most cards, neutral. So disable. $300 for good 16tb CMR drive. That's cheap. (I still remember buying 180gb drives for $300, for my early capture systems,) |

I've disabled DirectX under Video > Preferences > Display. Is that the area you were referring to? The various capture settings are attached. |
In capture mode, there are timing settings. Need to know those.
