the 656x480 is the preview pipeline.

@videodoctor Can you call ipl getimepath 0 while recording?

You bet, @0dan0 ! Here's the output while recording, with the original stock D firmware:

In hist.c Type A-C these addresses are different (same as each other)
uint8_t *imagebase = (uint8_t *)0xa2730b70; //start of LRV //PREVIEW

I have fixed hist.c to use these new addresses. Although as the D units are crashing before this, so no rush to try that.

Thanks for the continued investigation, @0dan0 . I'll see if I can get hist.c working now---I did have it calling during preview (and I think capture), but with the imagebase pointing to the wrong address in Type D, that might be why I saw it crashing.

I continued my investigation of sensor and ipl commands, and had Claude.ai look at the dumps and info. I ran:

Code: 
> ipl getcapmaxrawinfo 0

IPL(0) max raw width = 1936 height = 1076 lineoffset = 536870672
IPL(0) max raw ImgBit = -1 ImgPix = -1
> ipl dumpbuf 0

And Claude.ai gave me the following summary:


📊 Buffer Analysis - Proof of Native Capture​


PathBuffer SizeExpected for ResolutionMatch?
IMEP10x00334200 = 3,359,232 bytes1728 × 1296 × 1.5 (YUV) = 3,359,232✅ EXACT
IMEP20x00097e00 = 622,080 bytes656 × 480 × 1.5 = 472,320(with padding)
SIE_RAW0x002fade0 = 3,140,064 bytes1936 × 1076 raw Bayer✓


✅ Confirmed: Type D Captures at Native 1728x1296 (? Suspect ?)​


The IMEP1 buffer size exactly matches 1728×1296 YUV. This proves:


  1. NOT upscaled - If upscaled from 656x480, the buffer would only need ~472KB, not 3.3MB
  2. Native high-res capture - The full 3.3MB buffer is being used for each frame
  3. Path 1 is the capture path - Path 2 (656x480) is just for LCD preview


🤔 Interesting Mystery​


SourceResolution
Sensor max1936 × 1076
IMEP1 output1728 × 1296

Height 1296 > 1076! This means some ISP interpolation is happening to achieve the 4:3 ratio. But the quality is still far superior to the old 656x480.

Thanks for the continued investigation, @0dan0 . I'll see if I can get hist.c working now---I did have it calling during preview (and I think capture), but with the imagebase pointing to the wrong address in Type D, that might be why I saw it crashing.

I continued my investigation of sensor and ipl commands, and had Claude.ai look at the dumps and info. I ran:

Code: 
> ipl getcapmaxrawinfo 0

IPL(0) max raw width = 1936 height = 1076 lineoffset = 536870672
IPL(0) max raw ImgBit = -1 ImgPix = -1
> ipl dumpbuf 0

And Claude.ai gave me the following summary:


📊 Buffer Analysis - Proof of Native Capture​


PathBuffer SizeExpected for ResolutionMatch?
IMEP10x00334200 = 3,359,232 bytes1728 × 1296 × 1.5 (YUV) = 3,359,232✅ EXACT
IMEP20x00097e00 = 622,080 bytes656 × 480 × 1.5 = 472,320(with padding)
SIE_RAW0x002fade0 = 3,140,064 bytes1936 × 1076 raw Bayer✓


✅ Confirmed: Type D Captures at Native 1728x1296 (? Suspect ?)​


The IMEP1 buffer size exactly matches 1728×1296 YUV. This proves:


  1. NOT upscaled - If upscaled from 656x480, the buffer would only need ~472KB, not 3.3MB
  2. Native high-res capture - The full 3.3MB buffer is being used for each frame
  3. Path 1 is the capture path - Path 2 (656x480) is just for LCD preview


🤔 Interesting Mystery​


SourceResolution
Sensor max1936 × 1076
IMEP1 output1728 × 1296

Height 1296 > 1076! This means some ISP interpolation is happening to achieve the 4:3 ratio. But the quality is still far superior to the old 656x480.

> Height 1296 > 1076! This means some ISP interpolation is happening to achieve the 4:3 ratio. But the quality is still far superior to the old 656x480

656x480 is just the preview resolution sent to the display.

With a stock lens, even on D units, the maximum resolution for the active film scan will be around. 860x645, is only 10% higher than older models (from the slightly smaller pixels.) Going from 8mm to 12mm lens, is a 1.5X increase in X and Y res. So around 1290x960, in practice I'm seeing slightly more, like original lens in wider than 8mm.

As someone who scans with a Canon R5 and a Minolta Macro 50/3.5 on Minolta bellows and just happens to have a Kodak Eight Model 25 that hasn't been used yet (by me personally), this is an awesome project!

I develop color and B&W at home, so that's not a concern, I've just not gotten around to getting a roll of 8 mm yet since it only equates to about 2 minutes and 30 seconds of filming.

I also develop and scan at home. A modified Kodak Reels makes this hobby quiet practical and well as a lot of fun.

@0dan0, what's your confidence so far with the (now) five Type D variables in your custom mods?

Code: 
imagebase = (uint8_t *)0xa2c7b9b0; //Type D
expo_iso = (int *)0x80e5590c; //sensor ISO
nvm_base = (int *)0x80E0ADA4; //exposure, sharpness, tint
button = (uint32_t *)0xA0E8b7d0;

Also, in your res.c code, did you inject something to make consoleD() work? I'd like to add some print functions to my testing of hist.c.

I think only expo_iso is in doubt.

The trick to make consoleD() work is in the makefile. Text in color was added:

LDFLAGS = -Wl,--defsym,console=0x080160,--defsym,consoleD=0x080c60

# Default target
all: $(OUTPUT)

# Link the object files into an executable
$(OUTPUT): $(OBJS)
$(CC) $(CFLAGS) $(LDFLAGS) -o $@ $(OBJS)

P.S. I should receive my Reels type D in Monday's deliveries.

Thanks for that, @0dan0 . It will be nice, i'm sure, to have a D unit in your hands! The address for frameno in your hist.c doesn't seem to be incrementing during preview or encode. In earlier Claude.ai research, it looked like 80f82464 might be a frame counter, but it's incrementing on boot, even without an active preview or capture.

How did you find the frame counter and the encoded frames in your earlier mods?

Also, it looks like the encoded bitrate is around 8Mbps - 10Mbps with the stock H264 config, but I'm curious how difficult it is to find the H264 encoding parameters, particularly the GoP (aka keyframe interval), the profile (it's already High), and possibly the YUV color space. I'm not sure if anyone's tried to get anything better than the YUV 4:2:0 color space working, like 4:2:2.

The encoded frame count is something I added, all the data at 0x85bf00xx is generated.

Initialized with code at 0x339580

The encoder frame counter is incremented within the hooked denoise function 0x33a560

This encoder will not support 4:2:2. The GOP structure more be as it is it, I tried for all I-frame, no luck with that. My increased bit-rates are by directly setting the Qp value.

@0dan0 , i got the histogram overlay working, but it's flashing a lot, and I tried to add a for() loop in the draw section to make it more steady, but it didn't help much. Here's a recording of it. You'll see I've added little colored rects to the top right of the display to help me debug each stage of the calc_histogram() function. I've attached my current version of the hist.c too. I'm currently exiting out of the exposure section as it will crash when it goes into that condition. I think expo_base isn't accurate for type D.

Hi,
Thank you for your hard work.
I loaded your 7.62 "C" firmware on my Kodak reels serial C1725148BK00443 but I have 2 issues.
I can’t play the videos with the firmware (system crash)
I have flick video in the scanned film
do you have an idea to correct this
Thank you
regards

Maybe not addressing all six frame buffers correctly.

On unit playback is broken, as documented here https://tinkerdifferent.com/resourc...irmware-for-the-reels-8mm-film-digitizer.165/

Show your flicker. If this is frame move up a down, on the top or bottom edge, just rescan. That is know failure even with stock firmware (as seen here:
)

I think the buffers are correct as they all line up with the ipl getimepath buffer addresses---i think the issue is that AE function that you've previously hooked into has changed. After the frame counter is incremented in that native function, there's a modulus check for 3 which exits the AE function prematurely so that it only runs every third frame. There's no room between the increment of the frame counter and that check. When I NOP'd the return from that condition, the histogram is smoother, but still blanks out. I haven't found the exo_iso yet.

thanks for your replay.

Irescan 5 time with change parameters. but i got the same result.
I get some good result on firmware 7.40 with kp very high or original firmware.

Regards

what is kp?

Try v7.7. I'm use a Type C, and this happens on 10% or less of captures.
