Stop Motion with BMPCC, lighting?

Recommended Posts

I want to see if I can use the time lapse function of my bmpcc to create some stop motion clips.

 

I have googled lighting and I haven't found the information I was looking for.

 

What I am looking for is some inexpensive, flicker free lights. I would appreciate any suggestions.

 

Thanks,

 

Brian

Are you talking tabletop, like with miniatures?  You're going to be better off, if you are doing tabletop or miniature stop motion, to just do manual, single exposure rather than try to work with a time lapse function which will introduce increased possibility of error and unneeded tension while working, unless that's some part of your process, trying to only do what you can fit into the interval between exposures while getting out of the way.

 

Or, since I don't currently have a BMPCC, does it not do single exposure?

LED work lights are small cheap and filcker free

I have a whole bunch of them I cover them with LEE difuser and then use gels on them to alter the colour temp.

 

also these LED tube strips are superb ( as used on Only God Forgives film)  Ive just started using these this past 6 months to replace my Kinoflo lights as these are smaller lighter cheaper and flicker free they come in 3200k or 6000k colour temp

 

the 9w version is very very bright , I have built these into banks of 4 like Kinoflo

I've used compact fluorescent bulbs of the sort made for conventional incandescent lamp sockets in stop motion animation for years without flicker problems. I was shooting at variable shutter speeds with a stills camera. The lack of flicker does depend on the shutter angle, I believe, though I'm not very familiar with how shutter angle functions in relation to fluorescent, with regard to the Blackmagic cameras. The colors are nicer than cheap LEDs, but of course they're somewhat omnidirectional light sources so they're a little harder to control than an LED panel.

 

I'm curious as to why you want to use the time lapse function, maybe this is just a simplicity thing using what's available to you. I imagine finding a way to feed the HDMI video into the computer and take stills from there would be a little easier in the long run since some frames take longer than others to set up, and this would allow for reshooting frames when necessary, etc. The BMPCCs are certainly very appealing for stop mo purposes as they do not incur the shutter life problems that DSLRs do.

I agree with ergopossum. Use the HDMI and a specialized software like Dragonframe (or other). Then of course a camera with higher resolution offers you some possibilities like "digital zooms".

 

What you should not do, imho, is use frame interpolation functions or added motion blur. I loved the old Wallace&Gromit films, but I hated the cinema releases. They looked too close to 3D GGI, and that was very disappointing.

Hey, I work at a studio that does stop motion. I've actually been in this industry since the early 90's. So, any kind light that you on a live shoot works for stop motion. We use everything from 100K Arri's  to tiny peppers, and sometimes even simple incandescent clip on lights.  If you're really worried about light flickering just use longer exposures and avoid florescent lights. It's not really something that we worry about. More troublesome are the cameras that we've used in the past that have automatic/motorized Apertures. Every time you shoot off a frame, it's actually slightly different. when you view the frames afterword, there's a slight flickering. So we always use Nikon manual lenses. 

 

Anyway, Now that I read your question I'm thinking that you don't actually mean "Stop motion" but rather "Time-laps". The two are not the same thing. I don't know if you know this or not so I'll just state it to be clear: Stop motion is where you move an object/puppet in small increments utilizing the principals of animation and take a picture, and then do it again and again until you have a sequence of frames that can then be played back at real-time.

 

Time-laps is where you set up a camera to shoot frames at a very slow rate until you have a sequence to be played back. For this the BMCC is fine but for stop motion, you would normally just use a still camera and something like Dragon frame to help with the shooting and putting the sequence of frames together on your computer. 

 

Sorry if you know all that already I just wanted to be clear.

Thanks guys

Technically it would be time lapse frames to create stop motion. There is no way to grab or take stills that I am aware of on a bmpcc.

 

I didn't want to buy another camera or more gear for this and I wanted RAW frames. Sounds like trying to use time lapse for this might be painful though.

As far as recording straight into the computer, I was thinking of the use of an HDMI-in card like this card, or this one or this one. In theory you could use a card like that to record the clean HDMI out of the camera into a program like Dragonframe's live view. But this is a significant amount of extra money and hardware.

 

Wow Ergo, that first card is really inexpensive. I will have read more about it. Thank you!

      I single-handedly shot an entire narrative short film during the first lockdown, using the original BMPCC. The camera performed magnificently but I did have it fully rigged out. Shot using two SLR Magic primes - 10mm T2.1 and the 17mm T1.6. A one-person crew and one-mother cast, this is a film featuring my poor mum, who’s never acted, and a very, very unlikely hero…

      Jean-Luc Godard once said “All you need for a movie is a gun and a girl.” My mum doesn’t speak very good English, so I had to do without dialogue. I didn’t have a gun so we had to do without that too. We couldn’t leave the house, so I shot it all there. And I had no crew to help me, so I did everything myself.
      If anyone has any feedback or questions I'm always happy to hear!

      For sale a rare 1937 Leitz Hektor Rapid 27mm f1.4 cinema lens (s/n 417161) for the Bolex H16 cinema camera. The lens covers full m43 sensor with a little vignetting and soft corners, great for cropped sensor of BMPCC, BMMCC, BMPCC4K (S16 mode). Examples of photos taken on a Lumix GX800 camera.
      The condition for its age is excellent: the case is clean with little signs of use, there are some dust and a bubble inside (this is typical of pre-war Leitz lenses), I did not notice the effect on the picture. The lens has been professionally serviced. A complete disassembly, cleaning and lubrication was carried out. The focus and aperture rings spin smoothly and effortlessly. The diaphragm is clean, 10 blades. The kit includes the original hood, front cap and c-mount adapter - m43 (MFT) with rear cap. There is focus on infinity. I will send the lens by mail worldwide.
      I shot this video with this lens Leitz Hektor Rapid 2.7cm f/1.4 on a Lumix GX800 camera: https://youtu.be/uIRKYGp6tg8
