Why use a DVD recorder with an LSI Logic chipset?#1 - Removes chroma noise from analog sources
#2 - Suppresses grain from analog sources without blurring
#3 - Does not add digital artifacts like other chipsets (Panasonic, for example)

Machines were made in the 2003-2006 era.

Yes, the JVC units are best. And of those, the DR-M100 is best.

Note that I have a DR-M10, as well as a DR-M100. Both are excellent units. The 100 is a just a wee bit better on the encoding/ But know that I'm really nitpicking it. Most would never notice what I see.

I am not even sure that in Canada that DR-M100 an DR-M10 have been sold.

So far I only found DR-M70 for 10$ and JVC DR-MX1 for 80$ in classifieds ads.

According do this thread date about DR-M70 (and featuring guess who? ) may have the precious LSI chipset.

Thanks

the dr-mx1 is the same as a dr-m10 just with an added Hard drive and a shitty VHS player.
use it ONLY for the DVD recorder function.
and beware that model is notorious for the dreaded "loading" error
the M70 is a newer model and i dont believe it has FR mode

Actually I am trying to collect information because I am now in charge of the informatic in our small business. We had a ex-collegue that was doing capture with a DMR-ES36V. The new collegue that took charge of this project (basically capturing not soo important stuff, I mean nothing close to a weeding) was complaining about the fact that he can just record 1 hr with the dvd. Then I discovered that he though that he need to put the quality at max to get the better capture.

I mean probably not, it may depend of the VHS quality tape?

It bring me some questions.

Does the MPEG-2 recording format is 720x480 and if yes does it mean that I need at least 8 Mpbs
to be sure to lose nothing?

More is not always better, at least not when the bit-rate surpasses the resolution. Each resolution has an approximate bit-rate maximum, whereas sufficient bits (bandwidth) can be allocated to each pixel. While the MPEG will support bit-rates well into the double-digits, it will likely not use it, and the outcome is simply a bloated file.

352240/288 = 2.0 MB/s or 2000k max
352480/576 = 4.0 MB/s or 4000k max
720480/576 = 8.0 MB/s or 8000k max (same for the 704480/576 variation)

MPEG also has an option of VBR (Variable Bit-rate) or CBR (Constant Bit-rate). The VBR encode only takes the amount of data needed to make the picture look good, and has both maximum and minimum variables to work with. The CBR gives each frame the same amount of bit-rate and forces the picture to use it all, whether it was needed or not, resulting in larger file sizes.

FR mode?
It allows you to chose different Mpbs during the process?
I mean it's not like multi-pass vbr encoding where the amount of Mpbs needed is determined by the machine to avoid space waste!?


From JVC manual DR-MX1S

I can see that

XP ==> 10 Mbps ==> 1 hr
SP ==> 5 Mbps ==> 2 hr
LP ==> 2.5 Mpbs ==> 4 hr
EP ==> 1.6 Mpbs ==> 6 hr

Panasonic manual don't give the Birate but times are the same, I can assume that the birate is the same.

Thanks

FR mode is VBR - the FR155 mode works very well with VHS

Do you have access to that DMR-ES36V? I'm curious whether it straightens wiggling VHS lines like the earlier models.

XP is not ~10MBps --- that exceeds the DVD spec, by the time you add audio.
It's ~8.5Mbps at most. Probably more like ~8.0Mbps

Going from memory,
FR155 is around ~4.2Mb/s -- ie, slightly superbit for 352x480/576
FR180 is ~3.5Mbps

Somewhere in my old posts -- like 2006, probably -- are the more exact measurement. Myself and markatisu use to discuss them. Search this forum for them. I know I've copied pasted them before. I'd start by searching for "FR1155" and "FR180" and seeing what comes back on those. Use both the site search (power by Google) and the advanced forum search.
