Hello,

I'm in Europe (Sweden) and want to digitize NTSC tapes. I have a JVC HR-7600MS (which apparently is a multi-system unit, although the output appears to be coaxial only - I guess it's a bit ancient), and a JVC HR-S7700 (which, while S-VHS, doesn't seem to support NTSC).

What are my choices? Should I even attempt to digitalise through the HR-7600MS' coaxial jack? Or would a new purchase of machine be my best bet - in that case, which one? I would like to try to sidestep the need for a step-up transformer/expensive shipping from the US.

Thank you in advance!

No it is not worth capturing via RF out, You would need a NTSC VCR or the JVC HR-S7600AM PAL/NTSC if TBC and S-Video are required, This is the only S-VHS VCR in the history that is capable of doing 525/625 native scan and built in line TBC but finding the unicorn is probably a lot easier. So just get a US VCR.

Thank you for the answer.
Bummer.
I guess it's import time then.

Edit: A follow-up question. If I'm only meaning to digitize standard VHS tapes, would a S-VHS deck mean a significant improvement?

Most newer PAL VCRs can play NTSC tapes and output a not quite NTSC signal (NTSC 4.43, PAL60 or both depending on the VCR).

So, what I've used to capture NTSC tapes in PAL land is a VCR that can do that and passed the signal through a newer Sony or Pioneer DVD/HDD-recorder as those can handle these formats and do a decent job at correcting jitter as well (as the TBC on SVHS VCRs is not active when playing NTSC other than the mentioned multi-system one). They will output the signal as normal NTSC over the S-Video output if set to it in the menus.

The other method I've used is to pass the video through Panasonic DVD/HDD recorder like the DMR-ES10 using a multi-system deck (or a native NTSC one) with proper NTSC output, as the PAL panasonic DVRs do support NTSC as well (other than possibly the very old ones). The are very good at handling dodgy video signals and great at correcting jitter. They do only support standard NTSC though, so they can't be used with PAL60 or NTSC 4.43 output like the Sony/Pioneer models (which are not quite as resilient with very bad tapes). Multi-system decks that have standard ntsc (3.58) do seem to pop up now and then for sale used, at least here in Scandinavia. There are a bunch of models that don't have conversion functionality (and french SECAM support) that aren't overly expensive as they don't feature the extra standards conversion stuff and french SECAM playback that the ones mentioned in the guide have. (Some may lack hi-fi and not support all speeds though.)

I find this to work pretty well. A native NTSC SVHS VCR with TBC may give a tad nicer result, but I as olny get like a handful of NTSC tapes each year, I haven't seen enough need or quality issues to justify the cost of importing one.

S-VHS with built in TBC can be expensive here in the US as there is a surge in demand for them, What you could probably do is hunt down a NTSC combo VHS/DVD that can output component (480i), Such combo's are usually built in image stabilizer and output the signal via component (Red, green, blue) for the VHS section, Then just capture from component, Be careful, not all combo's output VCR via component, check the manual before you buy.

I have heard that some VHS/DVD combo's have S-Video out for the VCR and are built in image stabilizer I have yet to come across a model, The only units I've seen that have S-Video out and image stabilizer/line TBC are the S-VHS decks.

An actual NTSC JVC S-VHS VCR with line TBC.

Yes, significant. The main reason is the line TBC in the VCR.

And that signal is not to any actual format, so cannot be captured.

But the conversion of NTSC>PAL is not very good. This is an old cheat, and the side effect is linear/jaggy noise, off colors, and ghosting.

Not may, will.

This is a consideration. This is why I don't hunt down a better SECAM player, as I only get about 1 tapes per year on average.

Eh, not too much of a surge. Unlike frame TBCs, and certain capture cards, VCRs are still in the ~$500 ranges (+/- based on model, condition), with the AG-1980 being the main exception due to the refurb work needed.

But again, with degraded images quality.

Interesting. The first option is definitely an option, and I'll see if I can't get hold of a proper (non-coaxial) NTSC deck sometime.

Yeah... but if I'm getting a NTSC unit, why not just buy a VCR?

Very few, but I plan on slowly accumulating a bunch of NTSC tapes in the future. Not many enough to justify the importation of a NTSC deck from the US in my eyes.

Right. Makes sense.

I did surmise that, but seeing as I never have used a deck with a TBC, I couldn't really imagine the improvement. I'll take your words for it - and please do excuse the stupid question.

Interesting. I realise that this isn't meant for me to answer, but I have actually succeeded in getting a signal from a PAL ("pseudo-NTSC") deck (forgive me, I've forgotten the model number and I don't have it at hand) via an ezcap159 and VirtualDub. Not much colour, however, so no cigar. The sound was good though.

There isn't any NTSC>PAL conversion happening with NTSC 4.43 (PAL60 involved some phase alteration I think), the color signal is just upconverted to the PAL color frequency instead of the NTSC one, nothing else is altered. The luma signal is the same in all cases, the signal output doesn't have changed framerate or anything. I've never seen it cause any ghosting or jaggy noise when playing back NTSC on PAL equipment. The limitations are that some noise reduction and any TBC will be disabled, and that the video heads may be a bit less optimized for the NTSC track widths. I don't know how big of an impact the latter would have but if there is a notable difference it would probably be most noticeable with slower tape speeds and/or weak tape signals.

There is supposedly also some difference in the angle between video and hi-fi heads in NTSC and PAL/SECAM drums, but what effect that has in practice on a modern deck I'm not sure. (I think some older decks wouldn't do hi-fi in NTSC mode)

Many capture cards support the two pseudo-NTSC signals, but as people know they are usually crap at handling raw vcr output hence the suggestion of using a DVR that supports these formats. The AVT/Cypress TBCs handle NTSC 4.43 as well. The color will be converted to digital Cb/Cr component form internally in the DVR or TBC, so the color format on the output side shouldn't matter.

NTSC 3.58 to standard PAL conversion on the other hand, as can be done in e.g the format converting multi-system decks like the Samsung SV-x000W VCRs involve changing frame rate and number of fields, so that is likely to cause jaggyness and ghosting so it's not something that should be used for capturing.

If I have some time one day I could make some samples comparing the NTSC variants on a multi-system VCR if you are curious. I don't have a native non-NTSC VHS VCR on hand (though the SV-7000W we got is an US one I think as it has a US power plug), though I have the samsung and two other multi-system VCRs that can output in all the NTSC variants and record NTSC.

I do have a native Sony NTSC Hi8 camcorder and portable Sony Video8 player, but I don't have the equivalent PAL models. For the Video8 player (EVO-250) the video quality was worse than with that than with NTSC 4.43 playback on my PAL Sony CCD-TRV66, so if there was any quality degradation due to it being NTSC 4.43 it was less than the quality loss from using an older player.
