    Noise reduction

    Interview with a professional colorist at Dolby. Lots of tips and great info. At 24:40 about noise reduction. Also remember another interview with professional colorist, will try to find it where he said: "We apply NR to all material / video from digital cameras" https://www.youtube.com/watch?v=2K9oe7aEpdg
  2. Tried 10bit HDR Log V3 with my Samsung Galaxy 10+. Not impressed. Maybe it's better on IPhone 12. Keeping my EOS M for a cheap small and light camera with impressive image quality. Gorgeous colors, great resolution at 2.8K crop mode. Especially after 4K up scaling. Endless fun ML Raw at 2.8K crop mode from Zeek:
  3. Nikon Firmware 3.2 for Nikon Z6 and Z7. Adds ISO and Color Temperature control for ProRes RAW in Final Cut + BRaw support. https://www.nikon.co.in/en_IN/about/product_news?ID=templatedata/en_IN/taggable_content/data/news/products/Nikon Z 7 and Z 6 firmware Version 3.2&Category=product_news&Section= Nikon closes in Japan Factory https://fstoppers.com/business/nikon-reported-have-closed-its-japan-factory-ending-70-years-domestic-camera-539119 But says things are getting better now for the company https://fstoppers.com/news/nikon-says-things-are-getting-better-com
  4. Initially also used BMPCC 4K back LCD screen. But it is very uncomfortable to shoot with extended hands with and combo that weights 1.7Kg (BMPCC 4K + Speedbooster + Sigma 18-35mm f1.8 + ND filter). Also as you said, almost impossible to see in a sunny day. Tried viewfinder as well. Much better but still not optimal. And ended with external monitor. For run and gun it is the best option by far. Can hold the camera at waist level close to the body, no strain on hands muscles, monitor is quite bright (1700Nits) and viewable in bright day light. Monitor is permanently attached to the camera and it
  5. You can find S1 second hand with some warranty left for 1500 E/$. So even you have to pay for the V-Log upgrade it is still a very good deal. Panasonic S5 vs S1. In my opinion it boils down to one or two major differences. 1. Do you want a smaller lighter camera or not. How important this is to you. How often you will use it on a gimbal ? 2. Are you planning to record most of the time internally 10bit 4:2:2 or externally to ProRes RAW. If it is externally then S1 is the better option. It has Full Size HDMI. For S5 you'll have to add a bracket and a clamp for the micro HDMI
  6. Every camera has pros and cons. BRaw external for Nikon Z6, Z6 II is great. Problem for me is not the external recorder. BMPCC 4K, 6K have BRaw internal but can you use them without external monitor ? Not really. Nikon Z6, Z6 II with Blackmagic Video Assist 12G 5'' will be a smaller and lighter setup, not to mention that you get also a great photo camera, Full Frame out of the box, in body image stabilization, very good and compact EVF and much better auto focus in video. Can put the recorder in a bag on my side and have a HDMI cable hanging from the camera. No such big deal if want to
  7. For EOS M RAW video tutorials - visit Zeek's channel on youtube: https://www.youtube.com/c/ZeekEOSZ/videos It has piratically everything including how to set latest versions, etc.
  8. Yes did tested it, works great on Canon 5D Mark III. Really happy as 2:1 is my favorite aspect ratio. If one day real time live view in crop mode is fixed it would be truly a great Super35 RAW camera. Was thinking of selling my Canon 5D Mark III but now with latest development, no way it will stays with me. As one of the greatest DSLRs and great Super35 RAW camera too. Same for EOS M -2.5K 2:1 and 2.8K at 2.35:1 ratios are now possible. Again if real time live view in crop mode is fixed it will be a great Super16 RAW camera. Much better resolution than first BMPCC at Super16. And EOS M i
  9. Don't think that latest development from Bilal is part of this release. At least don't see it when testing this release from Danne. Preview was not working before in 3.5K crop and higher crop modes. There was a mess on the screen. In my understanding they fixed this. So now we have life view with correct framing but preview is still not real time and it is even worst when recording. Or when it is real time framing is not correct. Indeed Bilal made a huge break trough with real-time live view in crop mode with correct framing but it is working so far only on EOS M and not 100% ready yet.
  10. Thank you sam rides a mtb for sharing this information ! This HDMI capture card works very well with BMPCC 4K. Much simpler and smaller than my previous solution - Zhiyun Image Transmitter. With the transmitter can also control the camera but when monitor is on the top of the camera, can easily use camera own controls. Lag is acceptable, somebody measured it at 47ms. No worst than image transmitter or other low cost monitors. Picture quality is very good. Pinch to zoom for focus is available, false colors for exposure, LUTs, etc come from BMPCC 4K and are controlled by it. Can use a small ph
  11. Now we're talking. Wonder if external recorder improves the overheating problem. After all it's the internal processor which is the source of the heat. If they can just stream the sensor output to external recorder ? BRAW internal is not possible but external is. Let's hope Canon will give us BRAW external.
  12. It doesn't exceed my expectations. But guess we are all spoiled and with unrealistically high expectations. If the pixels for photo were 24M or more, then it would be probably a different story. 12MPx means this is basically a video camera in a small mirrorless form factor. Have experience with Sony A7S and Sony A7 III. Big difference in resolution for photos. Sony wants us to buy two cameras - one for photo and one for video. FF 4K 60p with slight crop ? Use it for more than a year. It's RAW internal and compressed. Camera also has 2.7K 120fp and costs much less. It's called BMPCC 4K 0
  13. BMPCC 6K has EF Mount. Yes there is no mirror in it but it comes from Canon DSLR and flange distance is 44mm, it was designed and used for SLR/DSLR cameras. By mirrorless mount mean short flange distance - 18-20-22mm. Like Canon RF mount which is designed and used in mirrorless cameras. So in my understanding not all BM cameras have mirrorless mount. m43 can't cover FF. So they have to borrow / implement a mirrorless mount from another camera system and most likely pay royalties. Andrew wrote in the article what would be the best solution. Bottom line is that EF Mount which covers FF won'
  14. On Blackmagic forum John Brawley wrote: Are you familiar with what some in the Southern Hemisphere call Christmas in July ? It's a major camera announcement, almost no doubt about it. BMPCC 4K and 6K still fly off the shelves, and are most likely profitable for BM. So it makes perfect sense to extend the line with a Full Frame body. If Z-Cam can do it, BM can do it as well. 3000 $ will translate to 3000 Euro and for that price expect - better body ergonomics as camera should be suitable to take photos as well. Old BMPCC4K / 6K shell/body is a no go for me.
  15. Was not able to extract more DR using Timur's workflow when compared to BMD film -> REC709 color space transform. But DR is very good and Sigma FP is still attractive to me as a travel cinema camera. Smaller form factor will let me take it with me more often than BMPCC 4K. Especially at this point when we know more or less what Canon and Sony will offer with new models. Willing to trade 4K 60P and BRAW for smaller form factor. Saw a polish review. According to the reviewer in APS-C / Super 35 4K image quality is still not optimal. But if in Full Frame 4K Sigma FP has to do pixel binnin
  16. Sigma FP caught my attention. It is more compact and has a better form factor than BMPCC 4K. You can add a small lens and put the camera on something like Feyu Tech G6 Max and have a very lightweight gimbal setup. And can take much better stills. It is tempting as a travel cinema camera. As bjohn stated in another thread will wait and see what Sony and Canon will offer, but Sigma FP suddenly climbed on the top of my cinema camera wish list. Found a very interesting article by Timur Civan. He proposes a workflow in Davinci Resolve which can extract 1-2 stops more dynamic range from Cinam
  17. Hmmm... Am not convinced this is true. And am not sure what non-destructive means. Everything that watch and read from professional colorists including Juan Melara's video point in the opposite direction. (HLG -> rec709 -> HLG = rec709) Let's check Melara's video. He concentrates mainly on dynamic range (Gamma). Whole point of the video can be summarized like this: URSA Mini is capable of 15 stops of dynamic range. But it looks you don't get all those 15 stops because BMD gamma is able to hold only 12 stops effectively cutting some of the dynamic range of the camera. Later he
  18. @Ki Rin It is in principle correct. Davinci Resolve timeline by default is REC709 color space and gamma. Same for Adobe Premiere. When you drop a clip Davinci assumes it is in REC709 color space and gamma. So without some form of transformation colors are not correct. You have to tell Davinci in what color space and gamma was your video clip shot in order to get the correct colors and gamma and use max quality of your source material. That's the principle, well explained in Russian video. As said one way is to use LUTs for transform, the other way is to user Color Space Transform or
  19. PS. As video shows method 3 is usable only if you shoot with Log profile or RAW. Only is this case Davinci Resolve will know how to interpret correctly the colors. For Panasonic cameras those would be V-Log and HLG and for Sony S-Log2, S-Log3(to avoid) and HLG (best). If your Sony camera doesn't support HLG, then only option would be standard S-Log2/S.Gammut Picture Profile. Or some kind of hybrid profile where Color Mode is S.Gammut and gamma is Cine2 or Cine4. But you'll have to experiment. Have no idea how footage will look and in Resolve there is no value that corresponds to Cine2 or Cine4
  20. It's a very interesting question. There are 3 methods how to approach the task and those 3 methods are actually different ways to structure your color correcting/grading workflow in Resolve. Color matching two different cameras has 2 steps: 1. Correctly interpret colors in Resolve for each camera. 2. Color match them if there are differences. Hint. If the first step is done correctly you will have very little to no work on the second one. There are plenty of videos on youtube but all they go straight to the second one missing the crucial first step. One or more cameras m
  21. In my experience 8:1 and 5:1 BRAW are OK for Sandisk Extreme Pro. My clips are short 10 sec to 2 min but so far never had a problem recording 5:1 4K DCI 24 fps on a fast Sandisk SD card.
  22. 220 ms latency, measured. It's there but can live with it. Don't have AccSoon Cineye, so can't compare.
  23. Bought Zhiyun weebill s image transmission module for 150E. In can be purchased and used separately from the gimbal. Works with any camera having HDMI out. Nice monitoring solution for BMPCC 4K. For 150E + my Samsung Galaxy phone or an older Samsung Note 4 that don't use got very nice OLED monitor with great colors, 800-900 nits of luminance and touch screen interface. All major tools, like peaking, histograms, zebras, false color are available. Even more interestingly, it communicates with the camera and you can set all major parameter like white balance, ISO etc. from the touch screen.
  24. Samsung T5 use TLC V-NAND memory/technology so problems related to SSD drives with QLC are not relevant. Small rig holders for Samsung T5: https://www.amazon.com/SMALLRIG-Bracket-Holder-Samsung-Compatible/dp/B07KW2B5C1/ref=pd_cp_147_1/147-3534738-4745748?_encoding=UTF8&pd_rd_i=B07KW2B5C1&pd_rd_r=4ba7f659-830e-45de-ba28-1fd2420d925b&pd_rd_w=k7mbp&pd_rd_wg=en7fQ&pf_rd_p=0e5324e1-c848-4872-bbd5-5be6baedf80e&pf_rd_r=5BBN4SQPTYQWJG8XN8HP&psc=1&refRID=5BBN4SQPTYQWJG8XN8HP https://www.amazon.com/SMALLRIG-Bracket-Samsung-SanDisk-Compatible/dp/B07X2PHMCF?
  25. A guy told you. Samsung T5 portable SSDs which are among the approved ones are 90$ for 500Gb and 137$ for 1Tb on Amazon. And that's cheap for me, cheaper even than SD cards per GB. https://www.amazon.com/Samsung-T5-Portable-SSD-MU-PA1T0B/dp/B073H552FJ/ref=sr_1_3?crid=1HC73MBGQQW2C&keywords=samsung+t5+portable+ssd&qid=1575587372&smid=ATVPDKIKX0DER&sprefix=samsung+t5%2Caps%2C252&sr=8-3 And on approved media BMPCC 4K has no limitations By the way tried a Micron M2 SSD in an enclosure just because of the smaller dimensions. And BMPCC 4K didn't recognize the driv
