I have read and heard that they usually downscale to something like 2k, 2.5k or 2.8k for editing and VFX but, what do they downscale from because, some camera's can record sometimes up to 12k but, nobody records movies in 12k i think it's because the file size and its not a lot better than 8k or 4k but it is still better but,
If they are using let's say 8k camera's what do they record in 4k, 8k 2k idk and let's take an example. What resolution did they record Avengers Endgame with? Do you know, well if you do then please let me know in the comments down below.
I am following the naming convention guide for multiple versions of video in same file and still noticing that they display as duplicates movies within Emby. Interesting is that the same naming convention for TV shows displays as intended where there shows a dropdown to be able to select versions.
Imaging the structure of molecules during a photoinduced reaction is essential for elucidating reaction mechanisms. This requires high spatiotemporal resolution to capture nuclear motions on the femtosecond and subangstrom scale, and a sufficiently high signal level to sample their continuous evolution with high fidelity. Here we show that, using high-repetition-rate ultrafast electron diffraction, we can accurately reconstruct a movie of the coherent rotational motion of laser-aligned nitrogen molecules. We have used a tabletop 90-keV photoelectron gun to simultaneously achieve high temporal resolution of 240 fs full width at half maximum and an electron beam current that is more than an order of magnitude above the previous state of the art in gas-phase ultrafast electron diffraction. With this, we have made an essentially continuous real-space experimental movie of the rotational motion of the molecular wave packet as it evolves from initial alignment and past multiple revivals.
I can see the difference when projecting a computer screen (e.g., Windows desktop, start menu, etc) in a 800x600 Vs. 1280x800 resolution for example. But when watching movies is there going to be a difference? It seems you will not lose any part of the picture regardless of resolution. Is this correct?
Still though, for projecting movies, the thing that matters is up to you when you're sitting in your seat. If you have a 4:3 screen that can only accommodate 1280x800 by shrinking the image far beyond the size of how 800x600 compensates with the movie, then maybe 800x600 is better.
Low-dose images obtained by electron cryo-microscopy (cryo-EM) are often affected by blurring caused by sample motion during electron beam exposure, degrading signal especially at high resolution. We show here that we can align frames of movies, recorded with a direct electron detector during beam exposure of rotavirus double-layered particles, thereby greatly reducing image blurring caused by beam-induced motion and sample stage instabilities. This procedure increases the efficiency of cryo-EM imaging and enhances the resolution obtained in three-dimensional reconstructions of the particle. Using movies in this way is generally applicable to all cryo-EM samples and should also improve the performance of midrange electron microscopes that may have limited mechanical stability and beam coherence.
Cartoon characters are not that heavy poly count wise compared to characters of realistic movies or even some game characters. 10 000 - 30000 polys for a character is not something you should be worried about.
Hi,
I am processing a super-resolution K3 dataset right now. I did the patch motion with 1/2 F crop and got a cleaned particle stack. Now I am planning to try whether local motion can improve the resolution. In the local motion job, it was performed in the raw movies, will the particles coordinate be adjusted since I pick the particles in 2x binned micrograph? And the particles extracted from local motion job, are these un-binned? Thanks

The aspect ratio is the proportion of the height and width of the image you see on the screen. We would often find black bars on the left and right of the screen if we would play an old movie on our new screens. These movies were shot on film and the ratios also impacted the televisions. Older televisions used to be shaped like a square box and suitable for watching 4:3 ratio movies.
Resolution on almost all the films seems to be below broadcast low def, Once Upon a Time in the West looks 720 or 1080 resolution, which I am totally happy with. But, most other movies on the Movieland.Tv channel play below the picture quality of over the air low. They are unwatchable. Who cares if it is free if over the air low def tv looks better?
I watch Movieland occassionally. Mostly older movies and I watch them on 1080 TVs mainly set to 720. These old movies look pretty much like I remember them watching them growing up. I do not own any 4k TVS so not sure how they look on them with the downgrading.
Movie resolution on the movie 'Airport' is unwatchable, with fuzzy graphics and bad sound. It has been going on for 1-2 years. How can that still be going on? You'd think Movieland TV or ROKU would have enough pride in their product to fix it or eliminate it.
Movieland.TV appears to be a pirate operation. A quick search finds that they have a number of films for free that are only available elsewhere on subscription services or as rentals, such as A Clockwork Orange, Rosemary's Baby, and High Plains Drifter. The resolution is probably low because that's all they could find on internet pirate sites.
This menu shows resolutions appropriate for movies based on commonly used video sizes (resolutions larger than that of your movie are dimmed). The exact resolution and data rate of an exported movie depend on the original.
In terms of resolution it really depends on their final target and whether or not they will be printing back to film or doing digital distribution. I would say that most work around a 2K format. or 2048 x 1024. Obviously a different aspect ration would create small changes in these numbers, but around that range is what most use. If your final output is standard 1080p HD TV, Blue Ray etc. then 1920x1080 is your ceiling. Either way renders never go straight from Maya or Max to the screen. It goes through some kind of post work always. Eventually gets final output from an Avid or FCP rig and then either gets printed to film or digital output.
2048x1556 - open gate 4 perf - 1.33:1. Typically film is shot using the full gate (the gate is the frame that sits in front of the film negative as it goes through the camera - the gate is the same size as your filmback settings in Maya). The full frame of film is generally scanned at this resolution, this allows some ability to adjust the framing later on.
I fell down a rabbit hole a few days ago trying to come up with the definitive answer to the often-asked question "how can old movies be in HD/4K", which immediately leads to "how does film and digital resolution compare".
The answer to the first question is of course that film as a lot more resolution than standard definition TV, so just scanning the movies at a higher resolution will give you a sharper image than that old DVD or (shudder) VHS tape.
(Actually a good VHS tape on a good player (my last one (at some point I had three) definitely doesn't qualify anymore) can look pretty good as long as the ridiculously low chroma resolution doesn't create problems.)
For reasons unknown, lots of people quote fairly ridiculous (to me) numbers, such as 20 megapixels for movies on 35 mm film. Between the advent of the 1.85:1 aspect ratio and that of Super35, a movie would effectively be shot at a 22x12 frame size.
Conclusions: even 70 mm movies don't materially benefit from higher megapixel scans than about 30. For 35 mm, it's over and done with at 12 MPX. (Which phone cameras have reached the better part of a decade ago.)
I pretty much agree with your findings on how many Mpix are needed for a fair digital reproduction of film images: Once you have the grainy film response across the image field, you can expect that higher resolution will mainly show more detail of the film capture noise. I think that already 6 Mpix maybe OK for Kodachrome II 35mm slides. I used a 24 Mpix crop camera and on accidentally archived the captures at 6 Mpix with little regret as the grainy film base shows consistently. I expect that the 45 Mpix of D850...Z9 cameras will be good enough for for 4x5 and more. But, I probably will not have a chance to inspect such images.
I found another interesting article about MTF/SFR. It states that the limit for useful resolution is MTF10. And with Norman Koren's Lorentzian function, we can see that the MTF10 should occur at 3 x the frequency of the MTF50. With that in mind, I'm revising my earlier calculations:
So it looks like 4k is a very good fit for 35 mm movies, except perhaps ones shot with high quality black and white film. 8k only possibly makes sense for 65/70 mm. But those tend to be old so I doubt there would be much of a difference in practice. And 8k is completely impractical because you need to sit very close to a very big screen to be able to see the extra sharpness anyway.
