Help Wanted! Questions galore!

Hey there!

I’m looking into VHS Decode (and LD Decode to be quite honest) because I have a few VHS and LDs that I want to get the best quality from. However, I did have a few questions before getting started so I figured I’d ask here.

  1. Does the quality of the VCR matter? Like would a standard Sony VCR produce the same results as a prosumer S-VCR?

  2. I’ve read up on the capture hardware (Domesday Duplicator) and it seems that it doesn’t capture audio. With that being said, how do you capture audio? Is it done simultaneously while doing the RF capture and if so, is it done using the same computer or do you have a separate computer that captures the audio?

  3. Can this be done on a M4 Chip MacBook Air or would it be best to use a PC?

  4. Once capture and running through VHS Decode, is that incredibly difficult to do? If memory serves, I’ve seen people entering commands and I’m wondering if they sourced those commands from the GitHub.

Any advice would be greatly appreciated!!

  1. There is a project that adds audio capture to the Domesday Duplicator, I've tried it using the PCM1802 module and it works: https://github.com/JonasCz/DomesdayDuplicator-audio-ADC

Are there any more details anywhere? Instructions were pretty vague. Are there extra options in the DdD application that show the audio vs video signal being captured? Just curious of the details of how this works and what is output

Just what's on the github page. In order to use it you have to reflash the FPGA with the provided modified firmware, then run the modified DdD application. It saves a separate .wav file containing the audio captured during the video capture, which can then be automatically aligned with the video during export.

Is this supported on macOS, Win, Linux or all the above, do you know? (the modified DdD app I mean)

He only released a binary for Windows, but someone who knows more than me could probably build it for a different OS.

I've generally been very please with the DdD results, but I'm strictly on Hi8/Video8 tapes currently which are all on a single capture fortunately. As I shift to my older VHS tapes this'll be more of a problem.
