  • Firmware DV-180N

    I just bought a Winait DV-180N 8mm and super 8 film scanner, it looks like a lot of similar devices on the net, such as the Wolverine Reels2Digital Moviemaker model. Website : http://www.winait.com/sdp/316052/4/p..._to_digit.html
    I don't know what the main circuit is used in this machine, there is a good chance that it is a Novatek, but I am not sure.

    My first attempts to transfer Super 8 to MP4 highlight a significant addition of noise on the final film.

    While searching the net, I found new firmware files modified by talented people to adjust the size and number of frames ([email protected] in particular).

    I see that there are tools to make these modifications but before testing I would like to be sure that I am not going to block my device, is it possible to recover the current firmware to make a backup before manipulation?

    Thanks for your suggestions.

    Vincent.

    Most likely you'll need to disassemble your device in order to get access to the flash memory chip. Then you can try to dump your stock firmware backup with a test clip and a flash programmer device.

    Do you have a firmware for your scanner or similar one from Wolverine/reflecta?

      Hello Nutsey, sorry for the delay, so in the meantime I contacted the Chinese manufacturer Winait and asked him to provide me with the latest firmware. In their attachment response I received their latest Firmware to date.
      So I was able to test with Wolverine firmware and revert to the manufacturer's firmware if necessary.

        Could you share these files?

      I nutsey, sorry, yes you can download it here : http://retromania.pandelground.com/w...tal-moviemaker
      I don't know what's the source code for this binary files, ideally I want to understand if it's possible to modify it to adjust
      some parameter of the scanner machine, the most critical point is the compression type used introducing numeric noise
      on frames. If you have some ideas please let me know.
      Regards.
      Vincent.

        This hardware can use only AVC/H264 and MJPEG codecs. The first one is set by default and does not introduce any visible artefacts similar to noise when bitrate value is quite high (~20-24 megabits for 1080p30 video).

          Hi Nutsey, thanks for the details, so it's clear with this hardware only mpeg4 usable but my actual frame rate is set to 16Mps can I increase it to 20-24 to see if the capture looks better ?
          On the site http://retromania.pandelground.com modified firmware bitrate is set to 16 for 1440X1080, can I found one with 20 or 24 or it's easy to build a new one using one of this ?
          Thanks.

          Thanks nutsey, I'll check & feedback to you !
          BTW, is there a way to decompile .bin file to add/modify some actions or parameters then recompile it ?
          Regards.
          Vincent.

            It is possible to reverse binaries with futher patching. To recompile anything you'll have to get the SDK with full source code.

              I tried the firmware: 1440x1080p24 with 24Mbps then after downloading to the machine I can no longer change any menus, each time I have on the screen: Please reconnect the power? !!?
              Then, I try to change the firmware with another, same problem .... When I turn on the machine, the screen is in black and white very dark, if I launch a scan the menu is in German it works but I no longer control anything ... Any idea?

              Hello Nutsey, thanks for the files. In fact I do not know if it comes from the firmware files, as soon as I loaded the first the red led of the device to flash for a moment then at boot the white led for the scan does not light up any more as usual.
              I have menus but I cannot access them, always the same message "please connect the power supply" it is inconsistent.
              I can start the scan, the white LED then lights up and the scan begins, but no settings possible! I do not know if there is a protection or if the device is broken, as I no longer have the original firmware I asked the manufacturer I do not know if he will send it to me .
              If not I did tests see here: http://dl.free.fr/n76TwGXkW there are 6 tests tips with different firmware, with the two that you sent me I don't have the same flow, the 20MBPS gives (via Windows properties) 28358Kbps and the 24MBPS returns 24899Kbps.
              Thank you for your support.
              Vincent.

                The noise looks like high-ISO film grain. I would record with the highest bitrate (don't trust windows properties - use 24Mbps fw) and reduce it in post.

              Well, I'm back, I asked for the latest firmware to the manufacturer and it send the 2020 one here: http://dl.free.fr/g23qTEMtL
              I'd like to have a bit-rate of 24MBPS instead of 8MBPS actually, with the same resolution 1440X1080 and I would like to
              decrease the the number of frames per second to 24 and best to 18. How can I do that please ?

              Thank you.

              Vincent.
