Slow-Mo Ideas / Requests Thread

(1/4) > >>

Nikon1:
As this Forum also has a Section that is for General Higspeed / Slow-Mo Talk, and we have a ton of people here which either own one or More Camera(-s) Capable of recording serious Highspeed-Footage or are at least interested in the Topic, i want to start a Thread here, were anyone can post & share Ideas and Requests on what to shoot in Slow Motion.
 Really anyone can post in here, this is meant as a place for everyone who isnt able to shoot what they want to, for whatever reasons ( be it lack of Human / Material / Financial Resources; Lack of time; Lack of a camera or other Gear able to capture what they are looking for; etc.); and also for people who have the Hardware like Lights; Cameras and Lenses, and have a hard time Coming up with good ideas on what to shoot like Content Creators for Youtube and Such or just People who are Looking for Ideas for a Fun and/or challenging Spare-Time Project.
 Would of course be nice if you would share your results here, if you end up using some of the Ideas here or doing any of these Requests, or at least link them here, but you dont have to, if you dont want to.
 .
 .
 Only Real Rules i want to set here are, that anyone Posting Ideas or Requests should do at least SOME Amount of Research if what he is looking for already exists somewhere. For example, please dont just blindly ask for someone to shoot Mousetraps or Balloons in Highspeed, as those two are probably among the Most commonly Shot Things in Highspeed, as far as Footage for Entertainment Purposes goes at least. For Those you would probably find Plenty Footage without even trying, unless you are Looking for something very Specific, like Closeups of the Point where the Hull Starts to rip apart or detailed Shot of the Trigger Mechanism going off or something like that.
 You dont need to spend weeks Searching, but doing at least one or two quick Searches on Google and Youtube shouldnt be too much to ask.
 If there is any kind of Footage of what you want to see, it would be helpful if you would post that as a Reference too (if there is any), even if its Low Resolution or otherwise bad and low Quality.
 .
 Also, while something like the FullHD @ 180fps a GH5 can Capture are sometimes enough to Capture decent Cinematic Footage (Slow-Motion), this isnt quite what this Thread is meant to be about. Highspeed-Slow-Motion is what i consider anything shot at like 400fps and more to be. Ideally of course 1000+fps, if possible or Practical. So, If everything you have is a Phone that shoots 480fps, you are very welcome to post, but 240fps or 180fps, which a Lot of DSLMs / Action-Cams Shoot these Days usually dont quite cuts it for this thread. If you have some outstanding Footage that is shot at lower Framerate, where there is little or no other footage anywhere, please still share, but i feel like to be shot at 180fps or more would be about the absolute Minimum in this case.
 .
 Anything requested or shared here should also stay within what the Forum Rules are (and also general legal Limits).

I am going to Start with a Bunch of Ideas/ Requests here:
 .  1. Super-Chilled Water freezing "instantly"
 I Personally encountered this so far 3 times in my life, once when a Co-Worker left a new sealed Waterbottle in a Fridge for a while, and forgot about it, to then open it and have it freeze in its hands unexpectedly (years ago), and about the same story with me by myself leaving a bottle of water in my Car over Night when it was freezing cold outside, and it then freezing when i opened it (not too long before it tried shooting that in highspeed).
 I Tried Last year for about two full Afternoons to get this to happen intentionally and get a good shot of that in Highspeed with the Chronos 2.1, but was not successful. I eventually managed to get it to happen once, but that was sadly not on camera, and all my further tries at this Failed.
 There seems to be a few people on YT who managed to get some Decent Quality Footage of this happening, but even after Searching for a While (to be fair i didnt do a recent search, so if someone uploaded anything within the last 6 Month or so, i wouldnt know about this rn.), there didnt seem to be anyone who shot this in Highspeed yet.
 Its a fairly challenging Project (or its just my fridge being weird, i tried with huge Bottles also, which probably didnt help) to get this to happen in front of Camera, as the Bottle will also freeze up on the outside, blocking the View.
 Would love to see someone do this with any Decent Quality Highspeed-Camera, especially Some Extreme Closeups of the Ice Forming, i assume that must be overwhelmingly beautiful Footage.
 I personally however dont really have the Time to keep Trying to Capture that, and am apparently doing something wrong with my cooling process anyways.

 2. Wire Break Testing
 Whoever has not seen these, here are two good examples:
 https://www.youtube.com/watch?v=RMZW1SX_rbk
 https://www.youtube.com/watch?v=E7ifgUuOukQ
 I am Fairly sure that would look Stunning when shot with a Proper Highspeed-Camera.
 Now There is a Video on the Hydraulic Pull Channel, but by far not to this Scale.
 https://www.youtube.com/watch?v=9Qlkm9px3YI
 The Real Test Sites for these huge Steel Ropes are just something completely else.
 Of course that is Stupidly Dangerous to shoot, but probably could be done with some thought put into Protecting the Camera and a Good Remote Control Setup (you dont want to be anywhere near that, when it snaps!).
 I also assume that this would maybe even give helpful information to the Companies who do the Testing, and might even be good PR for the Test-Site / -Company Itself if it gets some views on YT, so possibly mutual Benefits on this one.
 Sadly i dont know any kind of such Test Sites anywhere near me, and dont have the time to Build some Protection Rig for my camera to be able to do that.
 .
 3. "Classical Phantom Camera Theatre"
 https://www.youtube.com/watch?v=x__tpLzsLNc
 https://www.youtube.com/watch?v=HG64Isx0N2Y
 There are a bunch more Videos to that Series, but these Two are in my opinion the best of those.
 I love the Storytelling they do there with Highspeed. Never seen anything like this done ever after, and would love to see more like that.
 These were part of the Reason why i wanted to get into Highspeed back when they came out.
 I so far couldnt come up with a Proper Plot for anything alike, if anyone has Ideas Please Share them or Straight up shoot them, if you are able to.
 .
 4. Sound Design
 While i very much Respect classical / Traditional Sound Design for Highspeed-Footage like its currently used about everywhere, i feel like its time to start a new trend here.
 https://youtu.be/K8BDfoXm94I?t=673
 Lauri did that a while ago, and i very much think there is a lot more that could be done with not-so-Serious Sound effects. Almost everyone currently uses the usual fabricated Slow-Mo Sound of Layered Things Breaking and Hitting each other with a ton of Reverb, and i feel like its almost a overdone concept sometimes (sometimes it really adds to the footage though).

One thing my boyfriend keeps mentioning is exploding an electrolytic capacitor - I'm not doing it because it's too dangerous. Apparently if you get the right sort (cheap ones without a cross on the top) then they go up impressively. There are a few of them on YouTube but they are mostly really badly filmed and usually not slow-mo.

Might be a job for Lauri if he can get hold of a big one ;-)

Well, thats exactly what i am talking about ;)
 I will see if i can make something happen, have plenty Small ones around which i dont need (probably half a Bucket full or something, but not all in one place). Wouldnt be too big of a Problem for me to shoot that on the 2.1 some day. The Big ones however are buildt MUCH saver, so Chances of that happening are really low on the Big Capacitors, unless you have some very old and somehow Seriously defective ones.
 Once had some of the Big ones (where 8 Of them i think but dont remember fully, fairly big, not quite the size of a Soda Can Each) fail while in Operation in a big Inverter. That was (at least Visually) very anticlimactic. Was standing like 5 to 8 Meters away from the Inverter, and only thing you would notice was some Strange Hissing, like Gas Escaping Rapidly and some moderate amount of Smoke coming out of the Inverter Housing, followed shortly after by an overwhelmingly bad Stench. We had to power everything down, open every window and Door in that part of the Building for Ventilation, and that Smell was still very noticeably there the Next Day. Still not sure why they just Randomly Failed, the Entire Unit was Replaced Later under Warranty.
 Pretty sure wouldnt be very impressive on Video if you did that to one of these Big ones. The Smoke Coming out might be somewhat Interresting to look at, but thats about all you would get out of that, so usually not worth to Kill an Otherwise good, Big Capacitor for (and those are usually also not exactly Cheap). The Small ones are pretty much your bet bet for that, and they can indeed pack some Bang in them.
 .
 Seen Plenty of the Videos you are talking about, cant Quite Remember what they usually do to get the "best Results", but Reversing Polarity usually is really bad for those Electrolytic Capacitors (sometimes Voltage doesnt even need to be obscenely high for that, just wrong Polarity will usually do), and if that doesnt work, use AC Current on them, that will do it. Some people However will straight up put Mains Voltage on them.
 I personally wouldnt be too scared of doing that, even though i never did that intentionally so far, i am way more afraid of the Smell if anything (i can literally Smell These Videos of People doing that...). The Stench these Can (and usually will) produce is BAD. So if you do that behind some kind of Cover, so you are completely out of the Line of direct Sight of those (at least Eyes / Head, they dont have THAT much power, its not like a Bullet, where you have some solid Projectile. So even a Thick Plastic Shield or a Piece of Glass should be enough), have some kind of Protection for Your Front Lens (some clear Filter Will probably do), and wear Safety Glasses just for good Practice, you should be very safe in my opinion (no Actual advice though, if you do stupid stuff like that, do that on your own risk with whatever safety precautions you deem Appropriate.). However ABSOLUTELY do that outside your House because of the Smell.

Thank you for all that detail! I'll think about it :)
