Feedback requested for initial 8mm tape capture!
3 Attachment(s)
Howdy all!
I've finally finished putting together my capture gear for 20+ 8mm/Hi8 tapes recorded on several Sony camcorders over the years. My current setup is as follows: Sony EV-C100 Hi8 deck --> DataVideo TBC-1000 --> ATI TV Wonder USB 2.0 --> VirtualDub capture to HuffYUV S-Video interconnects are used throughout. Due to a potential Virtualdub issue I haven't dug into (can't adjust audio input levels on the ATI card?!) I'm capturing audio directly from the Sony EV-C100 to a Turtle Beach Santa Cruz card. I've attached three samples, all from the same scene. What I'm looking for is just some general answers to the following:
Thanks so much in advance! |
No, The top lines problem should not exist, It's either the player line TBC is turned off, it doesn't have line TBC or the external TBC is causing it, Post a sample without external TBC.

But I don't think it's the tapes here. I think the VCR is causing it. I don't like that deck. A better Hi8 camera with line TBC will probably do better at playback. Quote:

The third clip shows another kind of tearing when the camera pans.
The first and second clips show some horizontal banding in the blue balloon. I thought the TBC-1000 should fix it but I guess not. The brightness and contrast levels weren't set properly for a good capture. |
FWIW: The EV-C100 is a basic Hi8/8mm VCR and does not have a line TBC.

But just to re-emphasize, the VCR may actually be causing the tearing. The tapes may not have tearing present, and would play better even on another EV-C100 unit (but don't do that). The better the playback gear, the better the capture experience.
As always, Hi8 cameras are suggested for Hi8 or Video8 conversion. A suggested Hi8 camera is wiser choice the ES10/15 here. That's my point. |
Hmm, I'm seeing some high-frequency noise on the capture, it looks similar to something I get with the TBC-3000.

First off, thanks so much for the feedback everyone. I really appreciate it! As you've probably guessed by now, these tapes are pretty important to me and I really want to make sure I get this right!
Based on feedback:
As an aside, this tape played flawlessly in the EV-C100. However, when I played just the few minutes of it in my TRV318 and tried to eject, a length of tape had spooled itself around the pinch roller. A very unwelcome experience but one I feel that I'm going to get used to. I'll likely have to make another thread about this but I'm just curious, should tapes from the late 80s/early-90s experience a regular level of being 'eaten' or is there additionally something wrong with my camcorder? Thanks again everyone! |

However, old or new gear should not routinely eat tapes. If it does eat an otherwise good tape it likely needs repair/maintenance If in doubt, or if trying an unproven machine always test it with an unimportant tape first. Simple sharpness controls typically work by emphasizing "edges" (rapid changes in video levels in the scan line) and random video noise looks like edges so it will become more apparent when 'sharpness" is increased. Home video, especially video shot under lower light levels, tends to have a lot of noise in it. |
I had a similar issue with a CCD-TRV218 (from same lineup, but PAL model with a bit less camera stuff). I think it was mainly when using ffwd/rwd in my case though, don't remember if it happened on playback as well. What fixed it was tightening one of the tape guides a tad, I believe it was the one closest to the pinch roller but I'm not 100% sure, it's tiny so you need to be careful if adjusting it. (It was not one of the ones that move up next to the video head drum when playing and have to do with tape alignment over the head, don't mess with those.)
Also worth noting that the CCD-TRV318 only has mono output. Stereo was a later addition to the 8mm video format, it was mostly found on higher end hi8 camcorders and the Hi8 VCRs, so if you have tapes recorded on a stereo-capable device you won't get the full stereo sound (though the stereo separation wasn't always great.) |
Thanks again for all the feedback, everyone!

I may try to make adjustments, but at this point I'm open to just buying a replacement deck for this job. My last request here is a review of the second set of samples I uploaded. I want to make sure that the rest of my gear is working the way it should in terms of the TBC and capture card. I did adjust levels a bit to flatten everything down, and with the camcorder capture, the tearing at the top of the image is all but gone. Again, thanks so much for the feedback and patience! |
FWIW, 8mm/Hi8 audio was recorded as AFM HiFI (sort of) much bett4er than VHS linear track. It is comprised of a mono L+R signal, and if stereo a L-R signal that when added to the mono signal gave left and when subtracted gave right. All Video8 players can do the L+R track, but only stereo units will detect the L-R and give stereo output.
Stereo separation was driven by the microphone pattern and placement. In-camera stereo mics varied in quality and typically provided a restrained stereo image. but still could give an ambient presence/flavor to the sound. The 8mm tape helical scan is crowded. It contains space for video and AFM audio, time/data code, and PCM audio (detected and used only by select high end gear). |

The first two look great but the red channel is clipped on the right in the third one. However, I'm not certain whether that's a problem.
