And it looks like rear end. It may be cultural conditioning but suspension of disbelief just does not work at high frame rates for me. Nature documentaries would look great though.

I had the opportunity to keep a full set of reels for that movie. I passed as I couldn't be arsed carrying it to my car 50 metres away. As it was a lovely movie - I'm not that annoyed. But as I love random poo poo - I want it now.

Oh poo poo, I would definitely have kept that. Don't remember the film but I would have done something with submarine bits.

Same here. Back when they (Best Buy?) had display TVs showing off 120 fps interpolation with U-571 it made everything look like it was a bunch of cosplayers making a movie in their basement. I'd watch hockey on it though.

That would have been hz not fps.

Shouldn't 23/24 fps look all right at 120hz? That divides nicely. Or is it still 3:2 pull-down for some reason?

I agree with this. A bit of blur between frames makes the motion look better. 48 and especially 60 make the scenes look like obvious movie sets. I end up feeling like I'm sitting on the camera boom. It turns out I don't want a perfect reproduction of what the camera sees at high shutter speeds.

Exactly this. You can still get motion blur with higher frame rates of course, it's all about shutter angle. But 23.976 with a 180 shutter angle looks good with normal human motion.

People are welcome to their opinion on what they prefer, but saying there's no difference is just wrong, as someone who works with frame rates everyday.

Depends where you're watching them, but let's assume you mean at the movies. The judder from panning shots is the DP not doing a perfect job of the pan (whether due to time constraints or whatever). Cameras are tricky beasts and there are critical speeds where things will appear to judder. You may have noticed credits crawls occasionally looking janky as well.

Different frame rates handle vertical and horizontal movement differently. Without getting into too much detail, you're noticing it in 24fps movies more because there's overwhelmingly more of them.

IMO it's mostly because the footage is a blurry mess thanks to 24fps and corresponding exposure so it's uncomfortable to look at. Same thing can happen IRL if you move your head/eyes around too quickly so we generally don't do that.

What? What does exposure have to do with anything?

e: do you mean shutter speed like on a dslr? With film cameras that's shutter angle. You realize you can shoot at whatever shutter speeds you like with 24fps yes? People just generally stick with 180° (or 1/48th of a second in dslr terms) because it's pleasing to the eye, but plenty films vary it up for different effects.

It’s party the cinematographer’s fault for panning too fast, but also party 24 fps fault for making pans janky unless they’re executed at a glacial pace.

That's an oversimplification (there's lots of other things to consider, such as lens focal lengths) but sure, it's a limitation. But there are trade offs with absolutely anything you do and temporal aliasing is absolutely still present in higher frame rates.

e: again, I don't mind what people prefer I'm just glad folks are discussing the merits of each instead of writing it off as "no difference" or "something you stop noticing after 10 minutes".

Watching action movie type stuff on 120 for a few days then going back to 24 is painful.

Ok again, frame rate and refresh rates aren't the same thing. What action films have you seen that were shot at 120fps?

I like high frame rates for sports and documentaries btw.

e: sorry I did misread that, you did say action movie type stuff. What do you mean by that, is it stuff shot at 120fps?

I think that's a trend born out of bad choreography or directors (studios more likely) not able or willing to commit to the kind of precision you get from Hong Kong flicks. CA Civil War actually does have great choreography but they intentionally went for a chaotic style, which to me worked for the most part. Especially when they actually let the take roll. Lots of quick cuts and close ups usually means the fight scene didn't look great on the day. It's also much cheaper.

Cinema's all smoke and mirrors, upping the frame rate certainly removes a lot of the smoke which is most of the problem for me. A high frame rate kung fu movie could look incredible, if they nail it.

Once the independent scene gets a hold of cameras capable of this, that's when we'll see it done well just in time for big names to realise what they did to make it work and transfer it to cinema.

They kind of do, even dslrs can shoot 120fps at 1080p and the Arri Amira can do 100fps at 4k (well, upscaled internally from 3). As WebDog mentioned, higher frame rates is a huge amount of extra work for crew and post. Makeup in particular, even at 24fps something as simple as a certain shade of blue light can make prosthetics or make up look like crap. And ironically, a lot of indie work tries to mimic old school film look anyway so for them the more smoke the better. It's a crazy business.

The making ofs are pretty much on the same lines and are surprisingly candid. Also don't forget there's a bunch of web making ofs on the facebook page that go into more detail regarding how the 3D cameras were utilised.

One thing that does come through is that everyone did care deeply about wanting to make a good film but it really got down to the wire. There's an insane moment where they're finishing the final sound mix for Desolation and they realise that owing to time zones they are able to cheat in a few more hours.

Jackson is a perfectionist who cares and likes to challenge his crew. It's a bit cheap to compare him to Lucas as the people I know who worked with him on Clones were not really impressed.

Oh absolutely, that's a rough comparison. My biggest gripe with the hobbit films though still the scripts.

I hate when movies use a low frame rate as a lovely slow motion effect, or as a "technology" visual effect or whatever the hell. Maybe that's not actually low fps being used. Whatever it is, it's ugly to me. I'm failing to think of any examples right now but I've seen it quite a few times in random things.

Like I guess it's justifiable if your not-terminator is low budget in-story and thus has lovely camera eyeballs that don't update very fast but if you're doing that then you had better drat well use it as a weakness in the movie too.

Maybe the opening battle of Gladiator? When the battle sound drops out and the score rises up? That kind of look? Or more like the stuttery bits in the Omaha Beach opening of Saving Private Ryan?

The only other thing I can think of is when someone decides a shot that wasn't shot for slow mo now needs needs to be slow mo in post.

Initial tests shows that it works, though it does need a new ribbon. I've ordered one off of ebay that also has a red part, because red makes everything seem more important. I also saw you can get purple ink ribbons, which just seems classy as all gently caress.

Modern cryptoanalysis software could probably break an Enigma message in a few seconds, especially if they knew it was coming from an Enigma. With an electronic model of an Enigma machine as a base, your average desktop PC could break an Enigma code pretty much instantly, it already handles much more complex ciphers on a day to day basis.

I recently acquired a Canon 8‐T sexagesimal calculator.

It can do operations on mixed units of time directly. What’s 44 hours 7 min divided into ninths? Why, it’s 4 h 54 m 6.7 s.

It’s much more convenient than converting everything to seconds, doing the operation, then dividing back into minutes and hours, which I know I’ve done on occasion in the past. I assume spreadsheets are what killed sexagesimal calculators.

The Smithsonian Institution apparently thinks it’s pretty cool, too. They have one in their collection.

My question is: who was this machine marketed to? What professions do or did calculations like this frequently?

One field that comes to mind is time motion studies, but they attacked the problem from the opposite direction, using decimal stopwatches (marked in hundredths of a minute) to ease computation.

I love the design of this thing, and I'd also love one for work since I deal in time code a lot - but really just because it's so Weyland Yutani looking.

In Australia there was the 300 ohm twin wire then it went to 75ohm push-in type then the screw in F-Type. There are cable sizes like F59 and F6 but that wouldn't be your issue. Another possibility was it uses a female push in with a thinner inner core as used in car radio antenna a number of years ago (if it's this, buy a PS0614 from Jaycar, gut the inner and use the bare core as your inner point!)

Or if nothing above helps - post a picture of the connection compared to a regular antenna cable connector.
