  1. https://www.magiclantern.fm/forum/index.php?topic=24974
  2. Really exciting, but it only outputs up to 30fps 1080p (non raw) video. The API seems quite clunky, the way of getting raw data is by appending it to a JPEG file, so who knows if a raw video steam is possible. Hopefully the camera's firmware is open source...
  3. https://en.wikipedia.org/wiki/Lossless_compression I only wish magic lantern could use a lossy algorithm, we'd be able to get compression ratios over 3x.
  4. Please make a comparison of 14 bit lossless and 14 bit uncompressed. Lossless means exactly what it does, if you compress and decompress an image with it, the result will be identical, byte for byte, not just visually.
  5. I'm personally hoping we can get MLV in through the back door. I think it would be great if MLV could see some more widespread use, it is a very versatile format that should be compatible with any camera, open source too, which makes it the best option in my opinion. I am finding ways to convert all the main raw formats to MLV. I'm also writing a library that video editing software can use to support MLV. I downloaded someone's Sigma FP footage on this forum, and it converts to MLV easily. Opened up in MLV App: Also does anyone know where I can download more FP dng samples?
  6. Andrew could you upload a short video sequence of Sigma FP DNGs? I want to test it with a new tool I'm working on that converts any raw format to MLV raw video (MLV, from magic lantern as you know). It's called raw2mlv and source code can be found here: https://github.com/ilia3101/LibMLV
  7. If you have a 5D mark 3 there is no reason not to use lossless raw. There is definitely no difference in quality with the compression! It is lossless after all, not lossy. It uses the LJ92 compression algorithm, built in to the camera for raw photos.
  8. Thanks for the clarification! Luckily it is possible to get it under 200 fully working.
  9. Is it within the rules to buy the camera partially broken? Normally it sells for a little above 200, but I see one for < 150 - it has a mechanical shutter problem that affects only photos (I think!!!). EDIT: not a problem for me actually, as I just looked at sold on ebay and a lot of this camera are under 200 anyway. But if you answer anyway it may help someone else
  10. Totally agree about the 5D2 I love the 3K, such a pain in the ass to use, but really rewarding. I recently fell on my 5D2 and broke it (crunch), I could now upgrade to a 5D3, but I think I may just get another mark 2. Also - update on the 50D - the guy who's been working on the 5D2 seems to be getting somewhere: https://www.magiclantern.fm/forum/index.php?topic=19336.msg216752#msg216752 3200x1268 resolution may be possible (!)
  11. I'm 99% certain you are underexposing then, expose your footage as bright as possible without blowing out any/ too many highlights (expose to the right) - Use raw zebras in magic lantern to know where your highlights are clipping. MLV App does not even have any usable noise reduction, so I don't use it and still get good results, only in extreme cases I use the chroma blur slider to hide colour noise.
  12. Magic lantern is making a lot of progress with 3K+ on the 5D mark 2! Seems what happened with the 5 year old mark III in 2017 is now happening with the 10 year old mark II... 3K announcement: https://www.magiclantern.fm/forum/index.php?topic=19336.msg205638#msg205638 Initial 4K progress (10.5 frames per second): https://www.magiclantern.fm/forum/index.php?topic=19336.msg208417#msg208417 Initial 5K progress (6.5 frames per second): https://www.magiclantern.fm/forum/index.php?topic=19336.msg208355#msg208355 The 5D mark II has always been limited to 30fps, but there is also some progress in getting higher framerates: https://twitter.com/autoexec_bin/status/1048804509827452928 The forum user reddeercity has some builds on that thread. I am super excited about this, even spent 100 pound on a new motherboard to fix my camera. Video I made using the 3K build: Shot in 2880x1080 resolution, Graded + converted to ProRes using MLV App (https://github.com/ilia3101/MLV-App), edited in Pitivi on linuX. Lenses: Jupiter 9, Helios 44, Takumar 135mm, cosina 19-35 (for one shot) If anyone wants an MLV or DNG or something from the video I can provide.
  13. If it is linear data like RAW, then yes, you can only fit 8 stops mathematically, but in the case of gamma corrected data or LOG, the stops are spaced out more equally, in LOG they all get an equal amount of the range, it is LOGARITHMIC, so you could compress as many stops as you want in to the 8 bit 0-255 range, all the way up to 256 stops, if you want to give each stop a range of only 1. EDIT: I was BSing, just reread your post and realised you mentioned 8 bit out of the A/D @maxotics, 8 bit RAW is likely to look much worse than 8 bit processed 4:2:2 images, as RAW will have the 8 stop dynamic limit due to being linear. Although 8 bit raw would be fine if there's lots of noise.
  14. Thaank you!!! BTW your blog posts (such as "5 underrated cinematic images from “forgotten” cameras") are one of the reasons I chose to get a 5Dmk2 after owning a GH2! I really appreciate the love for old/inexpensive gear on here. And yep, the Helios 44 series is amazing for bokeh shots like that, especially when considering the price (the copy I used in that video was 5 pounds!!!) Just don't use it at f2.0 on a landscape shot... I ruined a few too many shots on a trip to Portugal last Christmas that way.
