I have found a viewer for it and can see the different frames, but there's no way to export it at all from the viewer. For now, I've stopped the quest for raw as finishing the physical build seems more important - though, that's also on hold for now too. What is the viewer that you use?

I think it's this, but I recently had to buy a new laptop and Catalina won't let me open it to check. Tomorrow I'll be with my other system, so will try to open it there and make sure it's the correct software. https://github.com/IENT/YUView/releases Quote Link to comment Share on other sites More sharing options...
rawshooter Posted July 13, 2020 Share Posted July 13, 2020 Thanks! And another question: which software did you use to record the raw image sequence/video? raspiraw? I wonder whether I should contact the PyDNG developer and ask whether PyDNG could be extended to extract DNG sequences. Quote Link to comment Share on other sites More sharing options...
Anaconda_ Posted July 13, 2020 Share Posted July 13, 2020 wow, that would be great. I tried raspiraw, but couldn't wrap my head around it. Instead, I created the process using this: https://www.raspberrypi.org/documentation/raspbian/applications/camera.md Quote All applications use the camera component; raspistill uses the Image Encode component; raspivid uses the Video Encode component; and raspiyuv and raspividyuv don't use an encoder, and sends their YUV or RGB output directly from the camera component to file. the same also applies to raspividrgb. but then you get a .rgb file instead of .yuv.

I filed a bug report on the Github page of PyDNG's developer, along with your Dropbox links to the original camera files, and received the following answer from the developer: Quote I took a look at those files, not quite sure how those would be processed. There is no metadata to specify frame size, number of frames, no presence of any notable header or EOF. What program did you use to generate those? Are you sure that is RAW Bayer data? YUV would suggest this is already demosiaced data and is transformed to YUV space. This is not what a DNG wrapper would be used for. https://github.com/schoolpost/PyDNG/issues/24 Quote Link to comment Share on other sites More sharing options...

When I’m home next week I can paste my python script for you to see each step. But it’s basically what I wrote above with extra lines for frame size and frame rate etc. Quote Link to comment Share on other sites More sharing options...
rawshooter Posted July 21, 2020 Share Posted July 21, 2020 The PyDNG developer has replied, and seems to be here on the forum as well: Quote So we have similar end goals I see ....saw your post on the EOSHD forums. The tool used to generate those files isn't outputting RAW, its already demosiaced at that point ( in either YUV or RGB space ) I haven't re-visited it yet, but the tool needed for RAW video is something like this one: https://github.com/6by9/raspiraw I don't think its officially been updated to work with the new HQ Camera. likewise I don't think it is possible to do the full sensor readout at 24-30fps, I think it was said something more like 10fps. However I think in the binned mode it can do 2K at 50fps so that might be a bit more feasible. Worth doing some more investigation, try asking on the RaspberryPi forums to see the state of raspiraw tool and if can be used with the HQ camera yet and what are the limitations.

Anaconda_ Posted July 22, 2020 Share Posted July 22, 2020 Thanks for the info. Raspiraw is a nightmare to figure out, and isn’t compatible with python. This is my first pi / coding project and implementing Raspiraw seems way beyond my level of understanding. I asked on the forums, but the devs approach is ‘if you need someone to hold your hand, find an alternative’ - which doesn’t exactly inspire me to learn his system. I don’t need hand holding, but reasonably easy to understand instruction wouldn’t go unappreciated. for now I’m just sticking to h264 but the nice thing is, its easy to tinker and adjust the code even when the rest of my project is finished.... who knows when that will be. For the time being. My focus is on getting a 1inch monochrome oled display to show the camera preview from boot until shutdown. If if it helps, I’ll happily share my VNC details in a pm and you can try your own codes etc, on my hardware. Just promise you won’t run a self destruct script.

no_connection Posted August 23, 2020 Share Posted August 23, 2020 Any updates or news? I have not really played with my pi since I use it to watch things. filmmakereu 1 Quote Link to comment Share on other sites More sharing options...
Anaconda_ Posted August 23, 2020 Share Posted August 23, 2020 For my project - raw video is still not working, and I've given up on it temporarily. I'm trying to get a small OLED display to work and show what the sensor sees, but it's being a pain. I've tried everything I can think of, and can't get anything to show on the display. Not even a 'hello'. Power goes to the display, but it doesn't seem to even turn on at this point. Until I can get that working, the rest of the project is on hold. There's no point building it into the Bolex until I can see what I'm shooting. I also want to cut any holes in the body in one go. I've had a busy summer though, so haven't even touched the project for a few weeks. Kids are back at school next week though, so I should have a bit more time to tinker.

marcusZol Posted January 2, 2021 Share Posted January 2, 2021 Looks like somebody is onto something here: https://www.raspberrypi.org/forums/viewtopic.php?f=43&t=296776 It can record 2028x1080 RAW DNG in 24fps.

kye Posted February 11, 2021 Share Posted February 11, 2021 Does anyone know if anyone is working on the h264 modes for this setup? The default was typical low-bitrate stuff, but maybe there's a chance of a higher bitrate 10-bit ALL-I mode? Quote Link to comment Share on other sites More sharing options...

PannySVHS Posted May 7, 2021 Share Posted May 7, 2021 On another forum someone was dreaming of a speedbooster for this to push it up to super 16 sensor size. Maybe time to rethink the classy classic EOS-M rather then waiting for a speedbooster for this little kitten.:) tupp 1 Quote Link to comment Share on other sites More sharing options...

If you're shooting RAW at lower ISOs then DR is one of the biggest contributors to IQ I find. Quote Link to comment Share on other sites More sharing options...
