On the fly, data is encoded and write to the sd card continuously. Auto stop is looking of about 20 frames of nothing.

If you want the best quality, just scan at 15, then roll back a few seconds, than continue when it crashes. Then re-assemble the clips in an editor. If you have a lot to scan, just change the Qp live, whenever you can, do not stop capture, as you can only change during capture. There is no...

Increase the Qp in captures are stopping. At Qp 16, scene noise/grain can crash the encoder (but it does look pretty.) Try Qp around 21 or 22. If the capture crashes, just restart of the unit.

This is a hardware design flaw. Read about it here, and some mitigation steps: https://tinkerdifferent.com/threads/hacking-the-kodak-reels-8mm-film-digitizer-new-thread.4885/page-2#post-42791

Unfortunately I still have a bricked type D, so nothing to work with at the moment. More importantly I will not likely have any free time for this project until late May. I hope I can then recover the D unit I have, and start again. However, a lot of the development will need to be from...

Start with the documentation: https://tinkerdifferent.com/resources/user-guide-and-reference-to-0dan0s-custom-firmware-for-the-reels-8mm-film-digitizer.165/ Most of the new controls are only available during capture. You have a C unit, no point installing B or stock firmware.

This is a new serial M2024 could be either Type B or C. Let us know what it is. Try B, if the screen looks weird, install C. Known so far: Serial numbers type and Models: A2021 A J2021 A M2021 A P2021 A A2022 A M2023 B A2724 B E3124 B D2825 B (outlier) H2324 C K3124 C C1725 C H2825 D K2225 D

The look up page hasn't be updated with the newer serial numbers. That is Type C. Fortunately it doesn't matter, you can install the wrong version, then install the correct firmware, and it will fine.

Only use 32GB cards, for better compatibility.

Please confirm if Type C firmware works.

CX is weird, but 1725 is likely Type C. Serial numbers type and Models: A2021 A J2021 A M2021 A P2021 A A2022 A M2023 B A2724 B E3124 B D2825 B (outlier) H2324 C K3124 C C1725 C H2825 D K2225 D

There is nothing much useful for Type D units yet. Type D is H2825 and K2225 models.

Please share the first 5 characters of your serial number. Like "H2825".

The vignetting is there, but easier to see with histogram on the Type A-C models. You can compensate for it, if needed. I just recommended against as for hacked firmware (with better exposure logic) it can slightly reduce the quality.

I did not use Ghidra all that much. From my memory there is an error message for when encoding is struggling with a high bit-rate, I use this to control the Qp. When I saw the warning, I increase the Qp 3 or 6, depending on the warning level. Set the Qp to 10, then using grainy film, that...

We now have to get the bit-rate up on the Type D, as you have achieved more resolution, but too much is lost to compression.

Unfortunately, the claims of the original product and the resolution written on the back, are misleading at best and a lie at worst. That low resolution number you're seeing is the actual pixels being used to produce the output. Any resolution you see in the MP4, is scaled up from this, no...

Don't reduce the aperture, as it adds vignetting. If you got the focus correct it is not needed. Love the hood budge, like you have supped up the engine within (and you have in a way.) Can you share any before and after scans?

Use a 32GB cards or smaller, or try formatting the card as FAT32. I think the large card support was broken.

hist.c is up to date. I did have the flicker, which just means it need to be called form somewhere else.
