  1. Cool - I try to accomplish the same thing with GH6 in 1.4x crop mode. I would like to see them head to head to judge the dynamic range and color rendition.
  2. The distance of the exit pupil from the sensor plane can affect image quality. When the exit pupil is closer to the sensor/focal plane, the angles of incidence at the extreme edges of the field become higher, possibly leading to pixel vignetting, depending on the sensitivity of the digital sensor to the angle of incidence. You could fix this with vignetting compensation, you could also fix barrel distortion with a small lighter lens design. If you had enough resolution and dynamic range you could put the exit pupil even closer to the sensor plane and then compensate for it when making the smallest, lightest, shortest, lens possible. Seems like Sony prefers this formula. If all other things are equal, then having an exit pupil further from the sensor so that light rays are more telecentric, is theoretically better. So adapting an EF lens to an RF mount as compared to a similarly spec'd RF lens without image compensation may provide a slightly worse image. Making a smaller lighter version of a lens on an RF mount should look worse without image compensation as compared to an adapted EF version with the same F Stop and focal length or zoom range.
  3. My assumption is it will have two modes: One with Global Shutter and lower dynamic range and worse low light performance and a second with Rolling Shutter and better dynamic range and better low light. I have a Z-Cam E2-M4 and it has a second setting with worse rolling shutter and better low light. They may not offer the rolling shutter mode, but if they do hopefully the RS will be acceptation and the low light and dynamic range will be improved.
  4. Seems like this will be a great camera! It will have to better the GH6 dynamic range wise for me to consider it. I suspect that this will not get 16, 15 or even 14 stops of dynamic range with global shutter and for low light or higher dynamic range modes, the rolling shutter will probably be bad. Prove me wrong Z-Cam and I will purchase when you have it on sale for $2,999 is 9 months. That said I wish Z-Cam all the best with this camera! I imagine one way or another, someday I will wind up own it...
  5. 5 Stages of Grieving: denial, anger, bargaining, depression, and finally acceptance. Looks like the screen actors guild is at stage 3: From https://www.msn.com/en-us/money/other/5-reasons-why-the-screen-actors-guild-is-striking-against-studios/ar-AA1e55Mv "...The studios countered with wanting to scan a background performance, pay the performer for half a day’s work, then use that performance and likeness in perpetuity without consent. The studios also wanted to be able to change the dialogue said by main actors, or even add new scenes, without the actors’ consent. Studios were also interested in using an actor’s likeness, image, and performances “to train new generative AI systems without consent or compensation.” I think the money is in training AI with the likeness, image, and performances of convicted criminals. My next movie and video game is going to star AI versions Ted Bundy and Jeffery Dahmer (they are both dead, so it keeps licensing costs down I assume? I wonder? Maybe the studios already own the virtual rights to their likenesses.) Bundy and Dahmer meet in prison and realize that they at one time were in same GYM glass, had a crush on the same girl, where both rejected by her, which was the last straw for each of them. It follows the retelling of their lives in parallel until each has their first kill. The academy award for best fantasy dark comedy tm goes to: Bundy vs Dahmer: First Kill tm Disclaimer no humans were hurt or killed in the making of this virtual movie or video game - it just looks, feels and sounds that way... we are not responsible for the therapy costs of associated with recovering from our media experience. Does anyone else have problem with a move maker/studio using an AI likeness of real serial killers to make horror films or video games? My point is if being famous is the fundamental value of an actor then we are surround by potential actors who the viewing audience my be just as interested in watching, if AI can do the acting for them... BTW - I love AI, plan to make the most of it for the benefit of humanity.

    Power Zooms?

    I've used Sony 28-135mm FE PZ F4 G OSS Full-Frame E-Mount Power Zoom Lens on Sony A7S MK II and the autofocus as not perfect due to the camera and there was noticeable rolling shutter when panning. The image was nice and when zoomed in from a distance had nice shallow depth of field wide open. I used it with a LANC zoom controller mounted to the tripod arm and it was able to do different zoom speeds smoothly. I think with a more recent camera like the A7iv it would have better auto focus and better rolling shutter. The one thing about it that was not ideal was the 5x zoom range. It was not enough for run and gun shooting for me. You can of course crop in post or possible do a digital zoom in camera, but I prefer to have a longer zoom range or a fast F-stop if it is a shorter some range. All and all the image was not the issue the older Sony camera was. On a more modern camera it should really shine.
  7. GH6. There is something special about V-Log with high dynamic range enabled and the Panasonic V-Log to REC709 LUT. I have never had such an easy time with color grading. I made the move up from the GH5 because I wanted better audio focus and to be able to record 4 channels of audio, which the GH6 will with the Panasonic stereo XLR audio hot shoe adapter.

    Panasonic GH6

    I have both the GH5 and GH6 and I prefer shooting with Picture Profiles on the GH5 and V-Log on the GH6. So the GH6 and its version V-Log looks better after post than the GH5 and it version of V-log. Probably not a right answer when it comes to the GH6: V-log or Picture Profiles are both great.
  9. Hi Eric, Happy New Year! I just used one of your song in a little video game I put together. It was just what the game needed. Thanks for making this valuable resource available! Mark
  10. Super 16 crop on the USRA mini Pro 12k offers: 6144 x 3240 (6K Super16) up to 120 fps with 7.8ms rolling shutter. 4096 x 2160 (4K Super16) up to 240 fps with 4.25ms rolling shutter.
  11. Once a year we have the opportunity to fill in the gaps or expand our capabilities at potentially the best prices of the year. What's on your shopping? Here's some of my favorite Black Friday discounted purchases: 1. Topaz Labs Everything Bundle (Topaz Video AI, Topaz Photo AI, Topaz Sharpen AI, Topaz Gigapixal AI, Topaz DeNoise AI) all for $279 2. Affinity Photo 2, Affinity Designer 2, Affinity Publisher 2, and the iPad version of each, all for $99 3. WaveLab 11 for 50% off and even more because of the exchange rate if you purchase through www.bestservice.com 4. Sonoris Mastering Compressor 25% off. 5. Relab Developments LX480 Dual-Engine Reverb V4 (basically a perfect copy of the Lexicon 480L dual engine reverb) for 50% off.
  12. Fantastic! I am wondering if anyone will use the time lapse record function for creating titles that with morph over time. I just checked their website and not only is it still on but you can get all of their apps for $20, basically, save you $10 off the previously discount price of $10 each. That said if you only get one, Rebelle Pro is the one to get. https://www.escapemotions.com/blog/ten-years-of-escape-motions
  13. Hi, Rebelle 5 Pro simulates water colors with realistic color blending and also does oils, acrylics, pencil and ink. If you ever wanted to try you hand at being a (digital) painter - get this deal - regularly $149 only $10 end Oct 13. https://www.escapemotions.com/blog/ten-years-of-escape-motions https://www.instagram.com/p/CjQb5Faq4yC/
  14. is this feature a big deal? “You can also use Ultimatte 12 to layer computer generated augmented reality foreground objects into a scene, complete with realistic transparency that your talent can walk behind” Could unreal engine 5 in real time to render both the landscape/background and a foreground image the transparency, while changing how in focus the foreground is based on the distance of the subject is from the camera based on AFX focus distance determination? Thanks!
  15. I’ve owned a number of those cameras (GH 1. NX1, BMCC 2.5k). I would say that the GH5 is a great low total cost of ownership camera. It’s 10bit with a decent bit rate for about $750 used. Maybe that’s more than people would consider cheap, but it is hack and hassle free with a broadcast quality image. So have we had access to great low cost icing images for a long time? Sure, but each had it’s challenges and flaws !
  16. A perspective from someone who mostly reads topics, sometimes posts when I have some to add and starts a new topic (very infrequently) if I think it would be of interest to other forum members. I come here for information about video cameras, what to added to them to make them perform better, and comparisons videos if there are 2 or more camera or products that might service the same purpose. Basically, I wanted to gain some knowledge and I am willing contribute if I feel like I have something to offer. Maybe create a camera, lens, lights, sound, production equipment database where forum members could contribute their knowledge and experience through product reviews, tutorial and answer questions that are posted to their product reviews. Everybody has a product they are passionate about and that are willing tell you about. Maybe create structure for people to contribute like a wikipedia for production, which has a questions and comments sections following the review. Oh an if I post a review of a product I get to provide a link to my Share Grid post so that I can rent it to them - maybe EOSHD gets a cut of the rental referral.
  17. Thanks Lilly, Looking forward to what you come up with! If you want to get us started with the second question about what makes up a camera tracking system for virtual production from antilatency and how it compares feature and cost wise to other professional camera tracking systems the would be a great place to start...
  18. @ohheylilly Welcome! We have a number of members who are interested in Virtual Production. Here's a topic for your review: As some people on this forum have professional cameras, lenses, focus and zoom controllers, lighting and green screens, if you would provide an example our how your system works for a non stationary camera (dolly or hand held) in relation to a non stationary subject (distance relative to the camera and focal distance is changing as well as the operator changing the the zoom setting) and a green screen background that gets replaced by a virtual background that changes its perspective and depth of field based on the relationship of the subject to the camera, the realtime reporting of the zoom and focus positions of manual zoom lens using the AFX system by our very own BTM_Pix, and in Unreal Engine 5. That would be greatly appreciated. What makes up a camera tracking system for virtual production from antilatency and how does it compare feature and cost wise to other professional camera tracking systems? Thanks for your interest in our forum and our virtual production needs!
  19. Will the URSA Min Pro 12k get this? I hope so. I also hope that the reset of the USRA Mini Pros and Broadcast get this as well. From what I have seen test wise (thanks for the tests! @FHDcrew and @Davide Roveri), I like the look and feel of the Gyro stabilization, it reminds me of a professional hand held shot rather than a gimbal shot which I am pretty sure I prefer the look of the Gyro. I would also like to see what a gimbal shot without a stabilized lens followed by Gyro stabilization looks like. Should probably look similar, but maybe Gyro stabilization will make it look more like hand held footage and hopefully it will be the best of both worlds. This a game changer feature for me as I like experience of shooing hand held, but it alway looks worse than I think it will when I review the footage. Now I can live in my movie making fantasy world and not have to appologise for following my creative impulses at the end of the day. Thank you Blackmagic!
  20. Very impressed that it is not 8k or 6k so it should have better low at $4.6k than if it were higher resolutions. I would love to see what 20 stops looks like compared to 17 stops etc... will it be noticeable? So will they have a Log 20 to 16 or 12 bit storage file bit depth to retain all of the dynamic range? They have been thinking about how deliver these specifications for a number of years so ti will be informative to see how they solve higher dynamic range capture.
  21. I came across a free leveler that is worth checking out (if you are on Windows.) https://luveler.blogspot.com/ It really has a great natural sound that reinterprets the dynamics to make it more natural sounding even if you only changing a the volume slightly. I am following a multiband compressor on the master bus and the make he compressor sound more natural. I have a feeling this is going to be a secret weapon of short as it can really reframe the dynamic response of a track or mix for the better. Thomas also makes Loudmax, which is a free limiter that runs on both Windows and Mac. https://loudmax.blogspot.com/ Both are worth checking out.
  22. The URSA 12k highlights are pleasing as well as their transition to being blowout is smooth. Skin tone are nice, but the color grading was a bit too green at times for my tastes... I like the full spectrum color rendering in day light. The sensor technology shows its advantages under the right conditions - full spectrum light if required to get the most out of this camera.
  23. Besides the Kinefinity MAVO Edge 6K Digital Cinema I am not aware of any other professional video cameras being released at NAB 2022. It used to be companies would book purchases with manufactures for the next TV season at NAB. This does not seem like a thing anymore, but I could be wrong. It really makes sense for there to be a $5k URSA 8k box camera with the same 12k sensor just with limited resolution and maybe a Canon RF mount and on sensor electronic ND. And at the same time release the 12k G2 with on sensor electronic ND audio for $6,995. There would be lots of people willing to upgrade for electronic ND's... maybe a late summer camera line refresh highlighting an electronic ND management system the always keeps the video signal under peaking and has meta data for smooth exposure ramping post.
  24. Looks like not new cameras from Blackmagic at NAB 2022... I installed Resolve 18 beta and it seems pretty stable (at least for audio processing). I did have it crash when I was trying to drag and drop an audio plugin from one buss to another buss, so I restarted it and copied the plugin settings, instantiated the same plugin on a difference track and pasted the plugin settings and it worked fine. Also, the same session opened up and played back the same audio plugin combination so it seem the there are not adding processing overhead to audio plugin in Resolve 18, which is not expected to be a problem, but it nice to see that it is not an issue. Does anyone know if it is $5 per month to host your projects on the Blackmagic Cloud or is it $5 per project... it seems like it is per project by I have not taken the plunge yet... Thanks!
  25. https://www.blackmagicdesign.com/products/davinciresolve/whatsnew I'm looking forward to many of the new AI masking features in Resolve 18. I imagine Resolve 18 will be at a level where many people who are on the fence about switching will not be able to resist the power of 18!
