Crazy times, the UK lately has also been batshit crazy, now europe wants to introduce digital euro. Some politicians in Belgium wanted to approve an AI that scans all bank accounts of citizens to find frauds... I can't understand who finds this a good idea??

Not much problem for christian nationalists who don't want to see non white tourists and non religious white tourists walk on their country's soil.

I haven’t been there for a while and was toying with a trip next year. To paraphrase King Arthur now though.

Yes. There is absolutely nothing wrong with the Sirui 35, especially for $500. I also expect Sirui to update their 1.6X lineup soon and add wider/longer lenses in the process. This is a really great time to be getting into anamorphic. There are so many great options amongst the newer Chinese made lenses...I can also recommend the Blazar Cato 2X lenses. I like 2X, especially with open gate and the Cato 85 & 125 are pretty nice lenses. I can get better results with an anamorphic adapter setup, but not without some hassles.

Filming job in US? Delete your social media
Yannick Willox replied to Andrew Reid's topic in Cameras
I guess you only need a couple of months to inventarise all your socials of the last five years. Is that including public forums like these ? also, every person you emailed, even if you got a new computer a year ago and do not have your complete history. On top of that all addresses and phone numbers of all family members, best friends, exes and current affairs you might be having. Probably that includes the number of deceased parents or family, if they did that within the last five years. so we basically need a P.I. to investigate ourselves to get into that shithole the US have become ? i think I’ll give a pass then … My guess is tourism will be booming the next couple of decades ! -

Yes my whole comment was on a "joke tone" and ironic as a mean to try to be "light" given the harsh and unbelievable reality we are all witnessing right now. I could've add "marple sirup" and "advanced Artic position related to Denmark" in the "unless they contain" list, that would have been more obvious I was being light. Sorry, not always easy to convey humor with text on sad topics (and not in your mother's tongue🫠). I need to rely more on spot-on British humor Gif like @BTM_Pix does😅

It's funny, because for so long these companies have resisted progress and had to be dragged kicking and screaming (see: digital media, streaming, etc.) but then when they absolutely SHOULD be resisting they have instead capitulated. There is an inevitably to it all, I suppose, but it's still pretty wild at how quickly they've jumped on board.

The Alexa has a really fast sensor readout, 2ms... motion cadence on that is of course fine as it is on all of ARRI's cameras, so that probably excludes fast readout as being the issue. Maybe some cameras implement the shutter timings differently to others? Say if you are in 1/50 or 1/40 or 180deg shutter the sensor might still remain in 60fps and it will just expose for longer and then the image processor converts it from 60p to 24p and then the codec maybe fudges things further with trickery like inter-frame compression and inter-frame noise reduction, whereas on a simpler camera like the Digital Bolex there is none of that shit and basically a global shutter sensor and entire image pipeline optimised for 24fps at 180 degree shutter. Maybe some of our modern mirrorless camera sensors have a true 24fps mode and others only have 60fps mode, process the 24p from that. Maybe some codecs are truly awful at motion... On the 50D it didn't have a video mode at release if I remember correctly? Magic Lantern enabled it via the raw video hack, but there's no H.264 mode is there? I could understand why some of the older H.264 low bitrate codecs hurt motion a lot, Cinema DNG and Magic Lantern were like going from digital video to film. The leap was that big. I should do some tests in Cinema DNG on my Sigma Fp-L as it is a direct sensor feed, uncompressed RAW and no pixel binning in the 1.3x crop mode. I bet that looks pretty good at 180 degree shutter in 24p.

So the news is in... https://www.eoshd.com/news/openai-decides-content-is-worth-paying-for-but-only-if-its-disneys/ OpenAI is being paid $1bn. Disney is paying them to license their entire range of intellectual property. You read that right... Disney is paying OpenAI! In return OpenAI will get to use Sora and other OpenAI tools - presumably they would have had to pay for these at some point so factored it into the $1bn. These tools will be used by Disney staff at HQ and in the creative process. In return Disney will also get an equity stake in OpenAI. This strikes me as a very good precedent for OpenAI. They are getting IP holders to pay them, rather than the other way round where OpenAI pays for content rights. There must have been absolutely no chance Disney could have won their lawsuit on copyright grounds for this deal to have any chance whatsoever. They must also have been persuaded that Sora AI fan videos of Star Wars would have an incredible social media reach for years to come, it's like free marketing isn't it? The guardrails must be really tight. No way are you making that Jabba the Hutt sex tape.

varicam 27h has 60p, 3 ccd thus global shutter no debayering, dps from 2000-2010 like its footage and see it as a substitute of 35mm film rolls. maybe ccd performs better even with a relative fast reading sensor?
-
when i pan with c300 og, the 50mbps mpeg codec makes the whole scene blur. i cannot see anything clearly. once the panning stops, suddenly the image is very clear. i just hate it. i use nanoflash's top codec 280 mbps mpeg and 30p and it is cured. when using ml raw cameras, i see clear images during slow panning (fast panning shows rolling shutter) at 24p. i almost always use 24p for ml raw cams to save bandwidth.
-
probably 50d has a really slow reading sensor. i know fs100 can do 60p easily so the sensor may be faster.
-
i think that andrew has a very good insight. maybe the r1mx, the eosm, gh1, do not have a fast reading sensor, so that more optimized (actually limited by the then technology) for 24p motion blur.
-
interesting, i like the r1mx and eos-m crop mood too. i did not use gh1 hacked before. may try it.
-
A primer on the fundamentals might be useful as a refresher too...

Ah, my favorite topic (and it comes up every couple of years). Hopefully we can have this discussion without the usual accusations. I've done a lot of personal experimentation in this area because most cameras looked off to me. Where I've landed is that I don't think that global shutter or CCD sensors is a surefire recipe for pleasing motion. I spent a lot of time and money figuring that one out. My list of favorite motion capture cameras is a motley crew and includes the Red One MX (but oddly, not the DSMC1 line), the EOS-M in 1:1 crop, and believe it or not, the hacked GH1.

Motion cadence will be impacted by every step in the image pipeline from the sensor onwards. The way to think about this analytically is anything that influences the quality or quantity of the motion blur within each image will impact the motion-cadence, or anything that lets the contents of any frame influence the surrounding frames. So it will be influenced to some degree or other by: shutter speed sensor modes (RS, etc) in-camera NR in-camera compression (codec, especially bitrate and IPB vs ALL-I, etc) processing in the NLE (NR, sharpening, colour grading, noise, etc) NLE export compression (codec, especially bitrate and IPB vs ALL-I, etc) streaming platform processing (NR, sharpening, colour grading, noise, etc) streaming platform compression (codec, especially bitrate and IPB vs ALL-I, etc) viewing device refresh rate vs video FPS mis-matches viewing device motion smoothing settings ambient viewing conditions and screen view angle etc I think of there being three dimensions within video. There are individual-pixel things that impact each part of the frame in isolation, like temp, tint, exposure, contrast, saturation, etc. There are spatial things where one part of the frame influences other parts of the frame, like softening, sharpening, halation, bloom, NR, etc. There are temporal things where parts of one frame are influenced by the content of other nearby frames, like temporal NR, grain algorithm, etc. We talk a huge amount about the first category, we talk anecdotally about the second one but no-one is really tackling it as a whole, and the third one is rarely even discussed.

Agreed completely on your assessment of the image characteristics. I truly appreciate the performance of classic anamorphic adapters and am happy that they are coming down in price. I just picked up a baby Kowa Anamorphic 8 2X for cheap and it's a jewel. A few examples of what I consider ideal performance below. First three are the ZIA 1.5x with an older Leica 50 Elmar collapsible, which is a tiny and wonderful combo that just covers full frame 3:2. Second is the baby hypergonar 1.75x with a Voigtlander 75 2.5, which also covers full frame but is a bit more muted (although this adapter can be fickle against the light sometimes).

I've been thinking about global shutter for a specific project, after being unsatisfied with test shoots using my S5. There are several to choose from now, but you're totally right that it's surprisingly difficult to find quality reviews or comparisons, particularly older models like the F55 in a modern context. If I move forward with it, I'll probably end up with a Komodo--but I've struggled to find direct comparisons between the Komodo, F55, Ursa Mini 4K, and A9III, not to mention comparisons with IMX410 cameras that I'm already familiar with.
