  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Nothing strange here except the 180 fps burst thing.
How long might you be able to shoot in that mode? If we speculate transferrate and stuff for the CF-cards.

Also, is it variable?
 
Precisely! I got some nice shortfilms and features in writing process and while they isn't action based, slow motion is such a powerful tool in enhancing emotions. There's also the possibility for me to create some nice looking material for clients and where I live there aren't many around that works with this so I will be leading my local market of commercials and moving images :D

Anyway, 120fps is good enough, but 180 burst is interesting, I just don't know how long you can burst. Is it like 10 - 20 seconds? Mainly for specialeffects like explosions and stuff? (If you can afford that there is)

Also, slow motion is very much needed if I'm going to make a sci-fi with scaled models... :D
 
If I remember well someone from RED has mentioned that this will be more likely in the 1 to 3 sec range. Consider that this will give You RT footage of about 22 sec.! With modern interpolation algorithms, such as the ones used in Shake, AE and The Foundry - You could further boost this to 44 sec. without noticeable artifacts - that is 360 fps!!! Interesting indeed...

Edit: I would be glad to be wrong on this one, as 10 sec will be much nicer...
 
3 seconds is better then nothing, much better :D
But 10 seconds would be good. If you create an explosion then there might be a 3-4 seconds delay before the actual explosion, so at least 7 seconds of burst would be good. It's not very nice if the camera captures half the explosion, there have to be little room for the editing room :)
 
And don't forget that it can only get better ;).

These new toys will really eliminate the "what will I shoot on" issue and help our conscience focus on the script and actors, which are the BIG ISSUES.
 
Absolutely! But not just help the focus on directing actors and all that, it's a powerful tool for storytelling. The thing that really is most shit on cheaper cameras is the lack of good looking slow motion.

I mean, the manipulation of time is what differ movies from theatre in my view. Theatre is here and now, in the moment. If directors only use one motion of time, then I don't think the storytelling is told through it's maximum.
And I'm not really talking about action scenes... I really love slowmotion walks; it's the best way to get inside the characters head during a transport from A to B in physical space. Just as an example.

My screenplays needs a rewrite, all thanks to Scarlet :)
 
My guess about the Burst mode is that Scarlet will not be able to record or compress the data at 180 fps in real-time. The camera will be equipped with a finite RAM buffer that allows it to rapidly store the information in a cache, and then complete the processing and write it to media.

To extend the Burst mode will require increasing the buffer size, and or increasing the processing or write speed.
 
Sounds correct, but what may be the maximum time to record in burst mode?
The buffersize should then be the messure for the length.
But if 120fps is the maximum realtime recording, then 180fps shouldn't be hard to record in at least 10 seconds of 180fps material?
(Don't have time for math, but what's 10 seconds of 180fps in 24fps?)

well. the calculator on my computer tells me that 180/24 is 7.5... which would make every second recorded play back for 7.5 seconds. 10 seconds would then be 75 seconds of playback, or 1 minute and 15 seconds. Now that would be plenty for most things for me...

this makes me ponder on the sustainable rate of 120 fps. 120 / 24 = 5. So every second recorded would play back for 5 seconds. 10 seconds would go on for 50 seconds, almost a minute. But it wouldn't be limited to a burst mode so I could make it go on and on and on and on (providing I have enough cards for swapping).

What I don't know is what the bit-rate per frame is in these modes, maybe the maximum of the "up to" numbers is a clue to it.

There is an issue with the readout speed as well, as normal sensors have problems with heatbuild-up, noise and consistency when you overcrank your readout clock speed. It could very well be both a RAM issue and image quality degradation that limits the time you can shoot 180fps. This is such an issue that high-end sensor datasheets have a chapter on this - describing the effects of different clock speeds.
I only know 'old' sensors though and the mysterium could behave in a different manner.

I was wondering about that too today.

Really nice ahm?!

:)
 
I think the first footage I will shoot with Scarlet is alot of dripping water/fire/kung fu and fun stuff... when I'm playing around with slow motion I really can't stop, it's a drug. It's like having a timemachine that actually works :)

I think my first footage will coincide with my planned course to learn the ancient art of pyrotechnics... bombs, squibs, all that...

did I mention that one of my heroes is called Woo? :shifty:
 
Slow-motion is a drug, yeah.

A professor at the university says that it's overdone and out of fashion, but I don't care.
 
For a nature docos (my favorite "past-time") slow-mo is a must! It's what separates film from video and what has been holding me back on the three docos I've managed so far...

When we were filming lemurs in Madagascar I wished every moment I had slow-mo option...

Slow motion is not out of fashion, I don't care if he's a professor or not.
There are certain things that can be targeted as fashion; like the use of minimal music and hard light in todays movies. But slow motion is a storytelling tool just as the use of bird-eye views or the total shot. I don't see how we can put slow motion under the catagory of fashion just because every action flick uses it? Slow motion can be used in so many ways and I think the professor should study the tool a little better then saying something like that. It sounds like he watched too many action movies, or didn't notice slow motion in non-action flicks.
 
This is what sold me on scarlet. 3K for 3K with 180fps bursts... I'm in love :-D!
