  1. I agree. I would add that "constant quality" (variable bitrate) works best for me. Here’s what has surprised me over the past two years with mirrorless video: I shoot 4K 60p in-camera at 200Mbps H265 10bit. When I re-compress this to H265 10bit In Handbrake (at many times slower than real time) at the RF 19 setting with “constant quality”, I get near identical image quality at only 10Mbps to 60Mbps depending on the subject matter. The scenes at higher bit rates (50-60Mbps) are outdoor shots with a lot of complicated textures from trees, grass, etc. But indoors shots with solid
  2. Apple is doing Windows users a big favor. It’s been mentioned elsewhere online that Qualcomm and Microsoft are working on ARM for windows. Apple’s M1 challenge is like the Russians sending up sputnik, no doubt it will accelerate Microsoft and the PC chipmakers work on Windows ARM. Everyone will have excellent machines for their preferred OS. Is your Current PC working smoothly for your camera’s video? I don’t need an M1 at the moment since I don’t use an 8K 422 camera and won’t for at least two years (Fuji X-H2?). Right now I am still amazed with my X-T3 and Intel Mini with T2
  3. This may be Apple's answer for that: https://debugger.medium.com/why-is-apples-m1-chip-so-fast-3262b158cba2?gi=sd half way down this article is "Basically you got two forms of parallelism: One that the developer must deal with explicitly when writing code and one that is entirely transparent. .. It is the superior Out-of-Order execution that is making the Firestorm cores on the M1 kick ass and take names. It is in fact much stronger than anything from Intel or AMD and they may never be able to catch up. To understand why, we need to get into some more technical details..."
  4. Here is a diagram I worked out for the X-T3: This is what I found inside my Vello remote for X-T3. I attached external wiring to 2 & 3 for remotely firing off frames when digitizing my Arri II 35mm timelapse footage, a frame at a time run by a geared down motor. The X-T3 results are excellent. My major project at the moment.
  5. "Apple is working on a new ARM-based processor with as many as 32 high-performance CPU cores that could appear in a Mac in late 2021, according to a new report from Bloomberg. The processor could also appear in a new “half-sized Mac Pro” in 2022. Alongside it, the company is also reportedly developing CPU designs with up to 16 high-performance cores and four power-efficient cores which are destined for new versions of the MacBook Pro and iMac. The new processors could arrive as early as spring 2021. Future Apple Silicon designs could also feature GPUs with up to 128 dedicated cores." http
  6. And here is the best basis for selecting a computer, the operating system you are happiest with. Most important I think. Mac users have traditionally paid more for Apple hardware than PC users paid for Windows hardware, precisely for the same reason, that they prefer the OS. (I am one of those.) But now for the first time (?) Mac users can pay a little less.

    Fuji X-S10

    Recently most of the forum topics have been about new FF cameras for $3-5 thousand, but I bet 90% of views on this forum are from people looking to spend $1000 or less. Even in the USA the average family savings account is only about the price of a new car, and for age under 35 the average is $10,000. If you do mostly hand held shooting and don't care about 4k60p, the X-S10 is the obvious choice for the IBIS. I compared the After Effects stabilizer (same as Premier?) doing walking/running torture tests, and the Final Cut Pro InertiaCam stabilizer was much better.

    Fuji X-S10

    according to this interview (https://www.imaging-resource.com/news/2020/09/04/fujifilm-interview-covid-gfx-strategy-shrinking-ibis-300K-cycle-shutter) X-H2 will come with "some sort of breakthrough", "something more revolutionary". Possibly global shutter? oversampled 6K60? AI boosted AF? Since they appear to be very ambitious for the X-H2, I am willing to wait. X-T3 is still all I need now.

    Fuji X-S10

    There are two Fuji choices right now for $999 (B&H information): X-T3 : for Video: 4K60p 10bit internal, no IBIS. (reduced from $1500) X-S10: for video: 4K30p 8bit internal, with IBIS. I would recommend the X-T3. I am happy with the video stabilization in Final Cut Pro, very adjustable with less "wobble" than IBIS.
  10. This hadn't occurred to me. I had to check this out. So do my Full Frame Nikkor zooms show the shallower FF DOF on my Fuji X-T3 after mounting on the Zhongyi Turbo II speed booster? I finally shot some tests and yes, they do. So, no need to switch from APS-C or MFT to a new Full Frame camera to get the same shallower depth of field from your FF lenses, if you need it. There are several good speed boosters (dumb or smart) that mount FF lenses with the added bonus of boosting light level by one stop, which you could use to reduce your ISO setting by half. Myself, I use the
  11. Actually, no. It's smooth in the viewfinder until you start recording the shot, then the intermittent auto ISO returns in 4k60. The pauses come at about one stop adjustment at a time, so not a problem at small exposure changes. 2K60 and 4k24, 4k30 are fine, no more ISO stepping even over a 5 stop ISO adjustment. If you are shooting with manual SLR zooms that are not constant aperture, the auto ISO will adjust the exposure for you smoothly as you zoom, at medium to slow speeds. Auto ISO response will lag behind fast zooms.
  12. Those quick tests were with the 10-24 zoom on continuous auto focus. I just noticed that auto focus affects the auto ISO smoothness at 60p. Switching to manual focus and viewing the auto ISO in viewfinder shows a smooth auto ISO exposure change at 4K DCI 200mbps HEVC 60p. Thank you Fuji.
  13. That’s because zooms cause aperture stepping even on manual aperture, which is not smoothed in this firmware update. (Except for 18-55 which did not step when the aperture was wide open.) I installed the update and did a few pans from a window view to an indoor view which showed very smooth auto ISO at 30fps. Every frame shows a change in video scopes luma so there is no stepping. Fixed! However, at 60fps I get pauses during the auto ISO, it adjusts smoothly for about 30 frames, then pauses for about 35 frames, then adjusts some more for 30 frames and continues intermittently like th
  14. I haven’t installed it yet, but- This is really REALLY excellent news. This new smooth auto exposure (ISO) solves my biggest problem with Fuji video. Auto ISO allows panning from sunlit areas to shadow, doing interior walk-throughs with changing available window light, and any uncontrolled situation where you don’t know how the light will shift during a shot. Which is often the case in run & gun video. Having to set a manual exposure is no longer necessary full time to avoid the flickering exposure stepping. You have a choice. Here is how it looks in the X-H1 https://
  15. Yes, it is a very good thing in the Fuji lenses. That's why I was asking about third party lenses, if they don't get corrections that puts them at a disadvantage. And I wonder where a particular lens's correction information is stored, in the lens firmware or the camera firmware? Just curious.
