Slo Motion test

With all the 60i footage at a 1/120 shutter speed I have shot for for slowmotion, none of mine has looked that good. Settings in camera and nle please!
 
its important to remember that the propper settings in your nle make a lot of difference. I want the new hc3 sony hdv cam it hs a 120i (240 frames) imagine the slomo it would make. drooooooool.....
 
Timur, the HC3 will be capable of 120p when deinterlaced using Ben's method, not 240p. 120i Means that every frame has 2 fields 60 times in a second. You can turn each of those fields into frames by losing resolution, to give you 120p, but you cannot double fields to gain 240p. Nevertheless 120p would still be impressive. Some 60i to 60p footage run through twixtor for 120p might be interesting.
 
Hi Guys, i cant remeber all the settings, it was all shot over a long period at different times. All the stuff shot in the warehouse was shot with the apperture open as far as i could and a shutter speed of 1/60 as the natural light in there is not very good. Other shots like the exterior red shutters was shot with a shutter speed of 1/1000 (if i remeber right) as it was a blindingly sunny day. The opening two shots where shot using my Century Optics 0.3 Ultra fisheye adapter, zoomed in slightly to get rid of the vig.
 
Awesome work Ben, so fresh all of your stuff. I'm gonna HAVE to have a play with my A1 and see what I can do for the DVD im making this summer! Inspiration!
 
Ran Bens footage through Twixtor to give effectivley 100p footage for super slowmo. This is my first test with Twixtor, didn't use any motion blur so I guess it could be slightly smoother. Because all of the shots are locked off it works well, meaning Twixtor only has to work with the small motion in areas around the skaters.

edit: as you can see Twixtor doesnt like the cuts, but obviously for real world applications you would slowmo your shots before editing.

There is a trick to converting interlace footage to Progressive footage in all NLE's. This has nothing to do with twixtor but with the way the footage is treated in post. Its well covered in barry greens book.

Essentially you stretch the clip out, until each field synchs up with a frame in a 24P timeline, the NLE turns the Fields in to "frames". the hc3's 120P is not progressive at all it is actually 240i. 240 distinct fields per second. when slowed down will make for rediculously slow 24p slomotion.
( check the sony site, it says, distinctly 240 fields per second)

hey was this with twixtor Pro, or the standard version?

I know the HC3 does not shoot a progressive image, I was referring to the method Ben used to create 50p from 50i footage using JES deinterlacer. I used twixtor to slow the footage down even further whilst trying to retain a smooth image. Ben and I have been practicing this for some upcoming projects.

If you enjoy shooting on the HC3 in 3 second bursts, go for it :p

Kerr Cook, from DVinfo says:

What I'm most eager to find out about is the "4x smooth slow record" mode where the camcorder records 3 seconds of video but plays it back in 12. Apparently recorded to the tape in 12 seconds, not some slow-playback mode. Although I don't think they can do a 1080/240i recording in 3 seconds (laid down as 60i over 12 seconds), that would be fantastic if it does! There seems to be this 3 second time limit, so there might be an internal memory buffer being used to "FIFO" the faster generated video from the image sensor to the slower moving (regular speed) tape. Also, the option is given to record 3 seconds AFTER or BEFORE the "start" button is pressed... which implies a ring memory buffer in action.

I suppose if the HVX users are managing with 4/8 mins on their P2 cards, the HC3 brigade will have to do with 3 seconds :p
I used normal Twixtor 4.5 for this although I do have pro here, its used for creating mattes and other crazy things I have not played around with yet. :)
