  1.   Wow 50D is looking very impressive, better than 600D.   Ssshhh don't tell ebay!!
  2. They probably put the lag in there on purpose so you'd find the C300 more attractive.
  3. The second video is genius. Very funny and original.
  4. The BMCC definitely has more room to recover the highlights and when they do burn, the roll off is very smooth and film like.   In the blacks though, it is noisy.   The 5D3 has less potential for highlight recovery by about 2 stops and when they burn, they stand out.   The blacks though are silky and clean.   So the cameras both need a different approach. I expose the BMCC to the right to bring up the shadows, but I expose the 5D to the left to preserve the highlights.   James Miller has a good eye. Enjoyed his footage. I did a flatter grade on my footage today, and actually prefer the colour and contrast in the original. It is just so good out of the sensor, it doesn't really need that much work in post unless you are going for a very specific stylistic look.   Of course the potential for saving a shot which isn't exposed correctly is enormous with the BMCC and 5D3 raw compared to normal DSLR footage.
  5.   Why are you saying this on a forum full of filmmakers. We know. Stop stating the bleeding obvious.   How in any way does the story detract from the camera. They are complimentary. It is like saying to an actor not to bother acting as well as they possibly can because the script matters most.
  6. Show isn't over for the Pocket Cinema Camera.   I suppose it is too hard to ask Mark to read anything properly.
  7.   Turmoil! Disaster! Drama! Raw for free.   What a hardship. Better image quality than a $15,000 camera on your $3000 DSLR and the first ever full frame camera to record uncompressed raw internally to compact flash card.   FOR FREE.   I don't call that turmoil I call it a miracle.   You're trying to justify a preconceived purchasing decisions I'm afraid. The Blackmagic cameras whole selling point - ONLY selling point - was the image and raw workflow. Nobody bought a Blackmagic for the smaller sensor, heavy body, poor ergonomics and slipped delivery dates. We held out for the image. Now we have it in a DSLR, along with a ton of other important features - stills, better physical controls, HDMI, full frame sensor, low light performance and all else offered by Magic Lantern aside from raw like peaking, high frame rates, zebra, manual audio, etc.   Magic Lantern is reliable. I can shoot all day at 1080p to my fastest CF cards without a hitch. Battery run times are similar to when shooting H.264! The rig is much lighter than my Blackmagic with external battery.   I own both. I cannot for the life of me keeping the BMCC EF.   Blackmagic still have unique selling points for me though.   A) The Micro Four Thirds mount camera B) 4K and global shutter on the Production Camera C) Super 16mm sensor on the Pocket Cinema Camera D) Resolve 10   But as for the BMCC EF - it's been nice. It's been lovely. But show's over.
  8. Does anybody actually know what the FS700 raw output looks like? Too early too call it on that one. What about pricing? FS700 is $8000 + $2000 minimum for the recorder (Odyssey 7Q) plus codecs have to be bought individually on top of that.   I'm calling it $11k minimum, close to the F5 price so you may as well get the F5.   All still very very far from $3000 and a free raw upgrade isn't it?   Don't forget how good the sensor is in the 5D Mark III. Very very clean, probably native 2500 ISO, 12 stops DR, not to mention full frame. I think people are underestimating it because they haven't downloaded any DNGs and have just watched the clips on YouTube.
  9.   The problem with MJPEG is the CPU power to debayer and convert raw to JPEG inside the camera. That takes a hell of a lot of processing power. The easiest thing for the camera to do is raw! Not H.264. Not MJPEG. Not ProRes. Not anything. Just raw.   Saying the camera could do 2k 60fps in MJPEG makes no sense at all. The CPU would not do it. Also the sensor mode only goes to 60fps with a vertical resolution of around 670.   With the newest builds we are seeing a 16MB/s improvement in buffer write performance to the card and that makes 1440x540 possible at 60fps. Pretty nice. If you want to add a massive overhead to this lovely raw performance, the quickest way to do that is to convert o MJPEG in camera... It ain't gonna happen!
  10. I'd say there's nothing in that F35 shot that the 5D Mark III can't match in raw.
  11. "Point to the ML hack"   Oh you are generous. Raw over laggy shitty looking HDMI is worth one point?   You're not easily pleased are you?
  12. I agree, good to know the info. Thanks Miguel.   It is good to bear this in mind with any bayer sensor. Red is interpolating to get 4K resolution, whilst the Sony F65 over-samples from 8K to do true 4K and true 4:4:4 colour.   With the anamorphic mistake - totally put my hands up to this one. In my haste to get on with shooting, I assumed I was getting 2.39:1.   It is actually 2:1 and the horizontal resolution should be 2560 not 3000. This is quite handy actually as it perfectly matches the native resolution of my Dell display.   Here are the other anamorphic resolutions for 4:3 and 3:2...   2x anamorphic from 4:3 (1770x1280) = 3540 x 1280 (2.66:1) 2x anamorphic from 3:2 (1920x1280) = 3840 x 1280 (3:1)   1.5x anamorphic from 4:3 (1770x1280) = 2580 x 1280 (2:1) 1.5x anamorphic from 3:2 (1920x1280) = 2880 x 1280 (2.35:1)   Do those aspect ratios look right? I'm not too sure.   I'll re-upload the video and it should look perfect.
  13.   I think 2580 x 1280 looks about on the money, which makes sense as 1720 x 1.5 = 2580!     I got 3000 x 1280 by assuming the Iscorama would give me 2.39:1 from 4:3. Seems it does not.   Will have a further look into this and likely re-upload the video tomorrow.   Cheers guys.
  14. As you said it youself you can do raw to RGB with 444 color sampling. Sure there's some interpolation but it isn't inaccurate to call it 444.   Same as calling the Epic 4K, 4K. It isn't REAL 4K. But it's still 4K. Get what I mean?   Also you don't actually know how the sensor is sampling 1080p from the full 6K resolution. It could be oversampling and downsampling from a higher resolution to achieve the 1080p raw for all you know. As you said, the way to get great luma and chroma res is adding more resolution and downsample. The image is so good that could well be happening on the 5D's sensor.   If you'd like floating point precision in terms of facts and figures from me, I'd be the first to admit I am not a mathematician but a filmmaker.   There's some stuff I'm still working out as I go, we learn every day as filmmakers and my blog is part of me learning as I go, sharing as I go. I think the anamorphic aspect ratio needs to be checked too by peer review, since 1920x820 is 2.39:1 and that is how I derived 3000x1280 - it looks however like the anamorphic isn't quite giving us that wide aspect ratio from 4:3 like I expected. Maybe it should be 2.5K x 1280. All to be tried! Still early days.
  15. You only get 16:9 from 4:3 with a 1.33x anamorphic lens.   The ones from the film days are 2x anamorphic. Iscorama is a 1.5x stretch.   Update: corrected the video, should be 2560x1280 from the 1.5x stretch of the Iscorama.
  16.   OK let's see what you've got.   You are welcome to post footage in this thread.   I have also made a group at Vimeo which has the rather catchy URL of https://www.vimeo.com/groups/raw   Thank you Vimeo!   You can add any of your Vimeo clips to that group as long as it is shot with the Magic Lantern raw module on a Canon DSLR. If embedded video in this thread please use your original Vimeo URL not the Group one.
  17. The LA7200 is lovely but on a full frame sensor it's not best suited...   It was designed for the small chip DVX100.   It works best at wide focal lengths, deep DOF, F4 to F11.   With a full frame sensor, wide focal lengths vignette with the LA7200 as they do any anamorphic adapter so you need to use a longer focal length. The LA7200 doesn't work very well with long focal lengths or the shallow DOF these lenses create.   You are better off saving up for an Iscorama or finding one for 70 euros in a second hand store like I did after 4 years of searching :)
  18.   A developer's branch of code had the 4GB cut off disabled and a tester on the Magic Lantern forums recorded a 12GB raw file in one take.   Yes Raw2DNG will need updating, all this is to come please be patient. That app was only put together about a week ago!
  19. If future CF cards and updates to Magic Lantern give us higher datarates then yes a 1:1 crop S35 mode at around 3.5K should be doable, it really depends on what resolution you can get in that mode.   If the full frame sensor size is a concern why not just use the Blackmagic Cinema Camera or crop or stop down the lens? I rarely shoot wide open on a full frame sensor unless the shallow DOF really suits the shot. Sometimes beautiful, sometimes not.
  20.   Interpolation. From Arri: http://www.arridigital.com/forum/index.php?topic=5204.0
  21.   Achtung! I said comparable not the same, and it really is. CMOS sensor technology has caught up with the F35's cutting edge 6 year old CCD technology in terms of everything but rolling shutter.   The sensor is way ahead of the image processor but with raw on the 5D you are taking the image processor completely out of the pipeline.   Therefore your colour science is almost entirely in post.   I wouldn't be surprised that the sensor was oversampling to get 1280p. It is a 6K sensor and if you line skip you get moire. There is none.   In 1:1 crop mode all the photosites are used, same as F35. In that mode I see very similar dynamic range, detail and colour to the 1280p sampling.   I'd like to come up with a post method that emulates the F35's film-rivaling highlights. I think it is entirely doable.   BTW the motion cadence is also superb but I shot this in a rush with no ND filter. My Vari-NDs don't work on the Iscorama as the front element rotates. This video is at high shutter speeds for the most part. You haven't seen the best of it yet. I'm gobsmacked.
