No big surprise.
Your ES10 screenshot is the 704x576 picture expanded by SAR 12/11 -> 768x576 (your screenshot 1)
The EH585 HDMI picture got deinterlaced, slightly cropped on the left (about 8 pixels into the active picture) and padded (or overscanned) to 720 adding black borders, then expanded by SAR 12/11 -> 785x576 (your screenshot 2).
As a capture and master for postprocessing I prefer the interlaced ES10 version. -

Turn off video stabilization, it works terrible. BEST on + mode: edit (just below BEST setting).

Got dvd player today ES10 but need to recap to whole PSU unite, it has 2 leaked and 1 buldged cap. It's working but funny working.
EDIT:
Ordered all caps, going to replace all 13 caps on power supply board. And two funny RJX and RJF caps on motherboard, hoping after that everything will be ok, I clean the player, clean the lens everything looks great now inside, except those caps that needs replacement.Last edited by Thermaltake; 13th Apr 2024 at 17:12.

Nevermind: I found out that ES10 only accepts NTSC3.58, not 4.43.Last edited by rgr; 19th Jun 2024 at 06:48.

Hi guys, any idea if there is a way to reduce the brightness of EUROPEAN DMRs used as passthrough?
https://forum.videohelp.com/threads/414910-Panasonic-DMR-E55H-%28pal%29-and-E85H-%28pa...ht#post2741803
i'm losing details on white spots... 3 DMR recorder are doing the same and the EUROPEAN firmware is lacking any adjustment. -
Just drop the levels a bit (Brightness and Contrast) in your digister's proc amp. I made up a adjuster box for the Luma line of the S-Video cable, but the result was basically the same as adjusting the proc amp. If you're not into AVISynth, I've written a guide on using Virtual Dub's histogram to set the levels here.

Isn't it enough to change the range afterwards?
From my extensive research it turns out that the details are not lost, but they are outside the 16-235 range. -
You can always make such adjustments as long as your luma is not clipped in the 0....255 range. However, when clipping happens at the analog level or by overdriving the A/D converter, adjusting the "proc amp" setting does not help to recover anything because one would only shift the clipped signal up or down. One cannot "unclip" the signal. What is lost is lost.
I put "proc amp" in quotation marks because with USB dongles (for example) these adjustments are done at digital level AFTER the digitization, means after the A/D conversion. So when the A/D converter or any other analog circuit in the signal path is overdriven (=clipping) these digital "proc amp" adjustments won't help to recover anything. One would just shift the straight and sharp horizontal luma values in the waveform monitor up and down.
Edit:
Here a demo how one can recover the picture when the luma is not clipped in the 0...15 or 236...255 range (superdarks, superbrights)
Edit2:
You can also use this demo clip to check how your player/TV displays superdarks and superbrights. If so, you will see something vaguely in the middle picture rather than just solid black or white.Last edited by Sharc; 7th Jul 2024 at 07:40.

As Sharc already explained, if you are able to recover them is because they are not lost, but captured in the range 0-16 or 235-255. But the procamps of most of the captures cards act only at digital level once the input analog signal has been digitized. It is helpful only to stay in the capture range of the capture card (that's why I always say to set to the capturable input range and not to 16-235 range) avoiding loss of not capturable details.
But if the problem is at analog input level, only a luma reduction before the capturing process (as showed in the German forum for the Panasonic DVD Recorders used in passthrough mode) is effective. -
The problem with capturing to the full or "capturable" (max.) range using huffyuv lossless for example is that some NLEs convert the YUV immediately to expanded full range RGB at import time. Means Y(0...16) and Y(236....255) get clipped, unrecoverable. See pdr's many comments about certain NLE's mistreating certain lossless YUV codecs. So one must "legalize" the YUV captures before opening them in these NLEs to avoid unrecoveralble clipping, or use an NLE which stays in YUV colorrange, or converts to float RGB.
Capturing to 16....235 a priori increases quantization noise / banding a bit though, but is otherwise generally safer IMO.Last edited by Sharc; 7th Jul 2024 at 17:27.

Yes, but is is better to capture in the allowed card range and then reduce the range to 16-235 in post-processing (AviSynth and dithering) rather than do it while capturing with the procamp

using PAL units, and connecting a TV at the video-out of DMR.. the brightness/luma level is much higher .. and details on very white areas are lost... this not seems to be related to the capture card not capturing 0-15 range... but just something wrong with the video chip that is doing the "stabilization" job)...
tried using any combination of Video inputs and video outputs... via scart composite... svideo.. component... same levels on output (too bright) -

Clipping of overly-bright details happens with both the NTSC and PAL units. You can verify that it's happening internally and can't be recovered on the capture card side by comparing to either a MPEG-2 DVD recording or HDMI capture, depending on the unit.
NTSC examples including HDMI captures: https://forum.videohelp.com/threads/319420-Who-uses-a-DVD-recorder-as-a-line-TBC-and-w...e7#post2341969My YouTube channel with little clips: vhs-decode, comparing TBC, etc. -
It's hard for me to comment on this, because I don't use DMR-ES15/25, only DMR-EH575/585. And I get a signal without clipping at the output (or in other words: there is data in the range of 235-255, and how much depends on the VCR). At least in the MPG file, but I suspect it's identical via HDMI.
And another note. By copying the same fragment of a VHS tape several times, you can get a different histogram each time, depending on what the VCR automation considers appropriate. -
When I click Display button on remote. I cannot get the menu to show up to turn off Line In DNR. Anyone know the problem? I am on the correct input.
