|
| 06:13 | BAndiT1983 | and before i forget, nice progress!

| 10:43 | EmilJ | Congrats on the USB3 readout working
|
| 10:44 | EmilJ | I loaded the DNG files into FastRawViewer, the pixels have swapped B and R values, right?
|
| 10:44 | EmilJ | Any clue about the cause for the constant noise pattern in the MP4? I can't see that in the raw files
|
| 10:45 | EmilJ | (viewing MP4 in VLC)

| 11:22 | se6ast1an | just loaded the DNG sequence in davinci resolve and can confirm that the raw pixel order seems swapped
|
| 11:22 | se6ast1an | image is blue instead of orange (tungsten)
|
| 11:23 | se6ast1an | and on the right edge there are some artefact coloumns
|
| 11:41 | anuejn | hm... thanks for the feedback re the color pattern
|
| 11:41 | anuejn | i will look into this
|
| 11:42 | illwieckz | left the channel |
| 11:42 | anuejn | I also noticed the artifacts on the right side but dont know where that shift is coming from
|
| 11:42 | anuejn | EmilJ: I cannot see any constant noise pattern in the mp4
|
| 11:43 | anuejn | can you explain a bit more what you mean with that
|
| 11:46 | BAndiT1983 | EmilJ: the constant noise is coming from the sensor, maybe swapped bits there
|
| 11:46 | BAndiT1983 | anuejn: he means the dark dots which do not move
|
| 11:47 | BAndiT1983 | e.g. when the table is shaking you see the random colored dots staying in place
|
| 11:47 | BAndiT1983 | *randomly
|
| 11:49 | BAndiT1983 | bottom row is flashing for me, checked in browser player and VLC
|
| 11:53 | illwieckz | joined the channel |
| 12:23 | anuejn | yup in the bottom there is a flashing area but that seems to be a conversion artefact
|
| 12:23 | se6ast1an | https://paste.pics/ea12b86ded896daddc428706988f9f38
|
| 12:23 | danieeel | anuejn: i see the constant noise pattern as well
|
| 12:23 | anuejn | ah hm... interesting
|
| 12:24 | anuejn | havent seen that til now
|
| 12:24 | anuejn | any guess what that is?
|
| 12:24 | danieeel | how did you made the mp4?
|
| 12:24 | se6ast1an | can you feed a test image into the acquisition pipeline in the camera?
|
| 12:24 | se6ast1an | to see what is coming out at the end over USB3?
|
| 12:25 | se6ast1an | that way you could easily asses if its something happening with the processing pipeline or if that is coming from the sensor already
|
| 12:26 | danieeel | in the dng i see some sharp dots, as if there was some coding/transmission error
|
| 12:27 | anuejn | se6ast1an: i can set the image sensor to produce a testpattern
|
| 12:27 | anuejn | I currently do not have any good testpattern generator in the fpga
|
| 12:27 | anuejn | danieeel: transmission error seems not too unlikely ;)
|
| 12:27 | danieeel | is it not compressed?
|
| 12:28 | BAndiT1983 | looks clean to me, i mean not compressed
|
| 12:30 | anuejn | it is not compressed
|
| 12:30 | anuejn | well... the mp4 is
|
| 12:30 | anuejn | but the dng sequence not

| 12:32 | danieeel | the ASN / WB is very crude in the file :)
|
| 12:33 | danieeel | or even the whole CM
|
| 12:33 | danieeel | i'd say, its horizontally flipped as well? or the text on top of bed is reverse?

| 12:35 | BAndiT1983 | webcam/front camera mode ;)
|
| 12:38 | BAndiT1983 | the noise pattern probably comes from the order of bytes in conversion
|
| 12:38 | BAndiT1983 | anuejn: what is the bit depth there?
|
| 12:39 | danieeel | yes, the image has too much noise and it just might be one swapped the LSB's of the 2 side by side pixels
|
| 12:39 | BAndiT1983 | danieeel: yep, exactly my thought
|
| 12:41 | danieeel | well, you can sell it as sort of Macrovision - high-def decode only for informed audience :P
|
| 12:41 | danieeel | (reminds me the GPS intentional noise injection)
|
| 12:43 | BAndiT1983 | haven't heard of the GPS noise yet, but know for decades the copyright injection into images, without changing the pixel info much
|
| 12:43 | BAndiT1983 | digital watermark
|
| 12:43 | danieeel | ehm: BitsPerSample = 8
|
| 12:44 | BAndiT1983 | but maybe original data is 10 or 12
|
| 12:46 | danieeel | assuming 8 bit would be linear, it produces heavy posterization after developing - which might be that visually strong fpn
|
| 13:01 | vup | original data is 12 bits
|
| 13:04 | vup | The noise could also be a sensor artifact at high gain
|
| 13:05 | anuejn | up the sensor is set to 12 bit and the data is then crippled down to 8 bit in the fpga for that example

| 14:02 | anuejn | https://github.com/apertus-open-source-cinema/axiom-recorder now has updated documentation :)
|
| 14:27 | Bertl_oO | anuejn: (regarding power via plugin) not without special wiring
|
| 14:27 | Bertl_oO | why do you ask? have you broken off the power conenctor as well? :)
|
| 14:57 | anuejn | no
|
| 14:57 | anuejn | I was just curious

| 15:25 | Bertl_oO | currently the 5V rails on the plugins are not connected
|
| 15:25 | aombk | left the channel |
| 15:26 | Bertl_oO | the 3V3 and VIO rails would be a very bad idea to power the Beta
|
| 15:26 | aombk | joined the channel |
| 15:27 | Bertl_oO | assuming that the 5V rails are wired up, they could be used to power the Beta but only for light loads as the traces are not designed for a lot of power
|
| 15:28 | Bertl_oO | and you could only power the microzed _or_ the beta at the moment
|
| 15:28 | aombk | left the channel |
| 15:28 | Bertl_oO | although it would be possible to rewire that as well
