EH75V has the passthrough of the ES15, but I'm not aware of the EZ48V having it. In terms of VCR playback, Panasonic consumer VCRs are overall pretty lousy.
EZ-48 compared to ES15.

I have not adjusted the levels to compensate for the blown-out whites of the 15 and 48.

Be vary that the North American models from around 2007? (that is with second number 7 and higher) and onwards including the ez48v use a completely different chipset and video ics to the PAL/International variants with the same label, and earlier US/Canada models, and may not do all that much jitter correction. I'm guessing the one hushpower is demoing is not one of the ones that were sold in US/Canada.

Yes, my ES15 and EZ48 were purchased in Australia, PAL Land. :congrats:

Thanks for the examples!

I am sure you already know it, here a guide from msgohan: https://forum.videohelp.com/threads/...15-DMR-ES25%29

The videos after the DVD-Rs are very good for jitter corrections but very bad for clipping whites, typical to first generation devices, mine ES-15 included; is not easy to avoid the level problem just using the procamp of the capture card (it may be too late). How do you normally proceed?

That is why the ES10/15 is best used only when absolutely needed, when the end quality is better. Restoration is often about choices, making it better not perfect. Ideally, for something like this, a Panasonic S-VHS field TBC should be tried before falling back to the ES10/15 Panasonic type strong+crippled line TBC in recorders.

@Robust: I foresaw the Betamax gear problem 15-20 years ago, and opted out of Betamax work long ago (even though it was frequently requested). Even back then, it was an ordeal to acquire working units, and have contingency plans for downed gear, including spare parts. Ugly. And it was only going to get worse. The 2010s were awful, and the 2020s are now horrible. Sadly, VHS is headed that way, currently an ugly situation to acquire decks and TBCs. By the 2030s, both formats will be in an end-game in terms of the media still being in good condition, as the final 2000s tapes enter that dreaded 35-65 year lifespan of tapes, and the 1970s tapes hit the end of the range (-65).

I could not agree more! S-VHS VCR with lineTBC is always first option; if it fails then ES10/15 usage is a "lesser evil", but for some tapes there are not other choices.

As suggested to my by Bogilein:

this can reduce brightness issue in PAL ES10/15 by lowering Y input signal.

Thanks!

I knew that tecniques, because I read often that german forum. The "custom" hardware is not easy to implement without degradation because we are in the analog domain, and the cards with "real" procamp are not easy to find...

If I'm right, the Y level must adjusted before ES10/15, if not the video information clipped by DVD recorder are anyway lost!?
Procamp is essential not in capture card, but before feed video signal to ES10/15, correct?

lollo2 01-08-2022 08:16 AM

As far as I know, yes to both. Bogilein and hodgey can help a lot here!

Edit: we are talking about PAL machines

Not to throw this completely off the top but I did have a couple of questions in regards to setup now that I have machines coming.
I am looking to clean up my workspace by putting my A/V equipment in a 4-shelf Server Rack. I will have room for three VCR units, my switch unit, stand-alone TBC, Surge Protector Outlet, and my Workstation Computer. Here are my questions:

1. I would like to put my Dell computer on the bottom of the rack and put one of my VCR units directly on top of it to save space. Is there any reason, such as inferencence, why I shouldn't do that? The Dell computer case is definitely strong enough to hold the weight of a VCR.

2. Does an all-metal rack cause interference in any way with the electronic components which could affect the digitizing process?

3. Any recommendations or advice using a rack cabinet is appreciated.

Thank you.

1. Heat.
2. It can. You'll have to set it up and see.
3. I had custom wood racks before forced to move years ago (health), even stained them nice walnut. The main reasons were cost and better spacing to disperse heat.

Heat is a constant concern of mine. I do everything I can to lower it, be it computers (example: i3 instead of i7), etc.
