The DVD recorder Panasonic DMR-ES10 table is one of my latest acquisitions. It may seem strange to purchase a DVD burner from table to 2016, where the high-definition digital video. But keep reading this article I'll explain the reason of the acquisition.
A few weeks ago, I decided to see how were the DVDs that I recorded from my VHS tapes for a little over a decade. At the time I did the tests with a CRT TV (I still had no LCD) and I thought the result great. I had done the scan with a PCI capture card, a Pixelview PlayTV Pro Ultra, connecting the VCR GSV-gradient 860HF directly to the Board. I recorded the sound PCM 48 kHz, without compression, and video with MJPEG compression, using VirtualDub. With the aid of the TMPEGEnc did the MPEG-2 compression and recorded the results in single-layer DVDs (4,7 GB). In some cases the resolution used was 352×480 and in other 720×480, Depending on the duration of the video.
As I mentioned, the result sounded great on CRT TVs of time testing. But today, in LCD TVs, You can see some macro-blocos and compression artifacts. Furthermore, There have been few tapes that captured in time: just my graduations and a few TV recordings. Many VHS tapes were stored without ever having been scanned.
I decided then that it was time to redo the old catch and also capture the VHS tapes that had not yet been captured, some more than 20 years and we don't know how long it will last and how long do I have equipment able to reproduce them. Happily, No mofou. All look in perfect condition.
The first step was to update the capture equipment. I don't even remember that has the Pixelview PlayTV Pro Ultra, Maybe it's still lost in some corner, I may have sold, but the fact is that my current PC or has more PCI slots. I decided I would purchase a USB equipment this time. USB 2.0 has enough band to stream video in 720×480 without compression, What is more than enough for the resolution of VHS tapes, so it is no longer necessary to work with internal boards.
There are guys who do cards hardware compression, What is unnecessary and undesirable, Once the current software do a better job. Furthermore, with editing and treatment, It would be necessary to redo the compression anyway. After searching, I decided to purchase a Diamond VC500, that is good, cheap and has drivers for Windows 10 from 64 bits. I can spare the half-assed software that comes with it and capture using the good old VirtualDub.
But if I'm going to do the capture on PC, What's a desktop DVD burner? Why not write directly with the DVD recorder Panasonic DMR-ES10 table? Explain. Desktop DVD burners do MPEG-2 hardware compression, usually bad, and still use a compression rate constant. This means that scenes of little or much movement are compressed with the same rate and, with this, the quick scenes tend to present artifacts. Software do a better job for using variable rate, and being able to use two steps, being the first to analyze the material.
This time also I would record more in DVD. I came to consider writing to Blu-ray, h. 264 video to SD resolution (720×480) and AC3 audio, but the lack of simple and functional authoring software let me down. Has only complicated software and software that you want to recode all the videos even if they are compatible with the standards. Finally I thought I might as well make MP4 files (h. 264 video / AAC audio) and leave them in My in, where can I play them easily and directly in two Smart TVs in the House.
And where does the DVD recorder Panasonic DMR-ES10 table in this story? Calm that I got there. To do VHS capture is highly recommended to use a TBC (Time Base Corrector) between the VCR and capture card. Tbcs are correcting the signal and/or the image quality of VHS tapes and other analog video sources. He receives a video as input, put in a buffer and the fixes before presenting it in the output.
Tbcs were largely used in professional video editing. Nowadays, with the prevalence of digital video, most models have been discontinued. The only model still manufactured is the AVT-8710, that's a reasonable price for a TBC (US$ 235,00), There is equipment in the genre that cost more than $ 1.000,00, When were manufactured. But with shipping and taxes, even the AVT-8710 It gets very expensive to be brought to Brazil.
There is no exact definition and accurately than a TBC must do, but two typical tasks are: reduce the jitter, that's that “balance sheet” the image that the image of VHS usually present and offer a constant signal and without defects to the capture card do not lose frames.
And the interesting thing is that many desktop DVD recorders also make some functions of TBC. Are not complete TBCs, but in general they do these two functions mentioned above, that is enough for a good VHS capture. Most of them only apply these functions in the signal that they're recording, but there are exceptions, especially the first models from Panasonic, When this feature is on all the time and applies including the signal going to the outputs. And this is precisely the case of the DVD recorder Panasonic DMR-ES10 table.
Subsequently Panasonic corrected this “defect”, so that the newer models no longer have this feature. Desta form, the DVD recorder Panasonic DMR-ES10 table is one of the few models that can be used as TBC, Maybe the only model released in Brazil with this feature.
DVD recorder Panasonic DMR-ES10 table as TBC
To use the DVD recorder Panasonic DMR-ES10 table as TBC, simply connect the VCR in one of your entries, and connect one of the outputs to the video capture card, in other words, the video just passes through it, without the recording function is used. The model sold in Brazil accepts PAL-M and NTSC video as input. As the PAL-M is used in Brazil, There's no point in importing the DMR-ES10 or any other recorder, because they probably will not accept PAL-M as input. A saída do DMR-ES10 is exclusively in NTSC, in other words, He also serves as transcoder. It makes no difference to the Diamond VC500, that accepts both NTSC PAL-M, but it may be advantageous if the capture card does not accept PAL-M.
The DVD recorder Panasonic DMR-ES10 table has both composite video and S-Video and composite video outputs, S-Video and Component Video. Any output can be used regardless of the input. I'm using the composite video input and output S-Video, avoiding mixing again chrominance and luminance (as happens in the composite video) After treatment made by DMR-ES10.
Interestingly the menus DMR-ES10 may be submitted in English, Spanish or French, but not in Portuguese. The Panasonic had the job of implementing the PAL-M in DMR-ES10, but it did not work to put menus in Portuguese.
One of the options, There is a black-level control menu (Black Level Control), with 3 items: “Input Level”, “Output Level (Composite/S-Video)” and “Output Level (Component)”. There is no consensus on what would be the correct setting, but I had the best results with Darker on the first item and Lighter no second. There is also a noise reducer of input (Line-in NR) that can be adjusted to Off, On and Automatic. How best to leave noise reduction to be made in software, leave this option in Off.
I'm liking a lot of the work of the DVD recorder Panasonic DMR-ES10 table acting as TBC to my VCR GSV-gradient 860HF. My catches are really doing better. The image is more stable and also don't miss a single frame.
Transcoding of DMR-ES10 It is also far superior to what I used to see in dedicated transcoders, like Transcortec and other companies.
I'm convinced that I'm doing the best I can with these catches, or very close to it. In international forums, where people have access to professional equipment more easily, the DMR-ES10 is fairly cited doing a good job as TBC, being also used by professionals in many cases.
As for the video tape, in international forums the JVC is highlighted as one of the best brands. In Brazil, unfortunately, not been released many of the best models, including those that have built-in TBC. And there's no point import, because the imported will not be able to read tapes in PAL-M, that is the case with the vast majority of my tapes.
The Gradient had partnership with JVC for many years. De fate, many of the latest models of JVC VCR in Brazil were manufactured by the Gradient in Manaus, and many Gradient models actually used JVC technology. My GSV-gradient 860HF is one of the latest models launched by the Gradient in Brazil, has 7 heads and Hi-Fi Stereo sound, and uses technology from JVC. Is one of the best video tapes released in Brazil. How hard it is to find a VCR today in good condition, I don't intend to change it and I hope he does not present problems.
In my research I found only two models of the Gradient that believe they are more recent than the GSV-860HF: the GSV-870HF, as the number in the model leaves somewhat obvious, and the V7, What I believe to be younger by be Silver instead of black, following a trend for electronic equipment that appeared there in silver early 2000, and from which the Panasonic DMR-ES10 also part. Today this fashion already over and the equipment returned to be black.
Note that I'm not talking here about the functionality of the Panasonic DMR-ES10 as a voice recorder and DVD player because I do not wish to use these features. Playback of DVDs and analogue channels tuning I even tested. But the burning DVDs I didn't even test, because he only accepts DVD-R and DVD-RW, and I didn't have any on hand, mine are all DVD + RW rewritable.

Wait for the article on the Diamond VC500, where I will speak and show you a bit more about this process of capturing videos from VHS tapes. Cogito also make a small series about the details of this process, including capture, editing and restoration, If there is interest from readers. Leave your comment.
