HD slow-motion demo/test of the Sony FX1000 and additional pixel tracked slow-motion.
(Andrea is doing all the running. Thanks hunny!)
Music by Mark Pledger ("Time stands still" Andy Duguid remix).
Nerdy techy stuff follows:
With recording speed of 100 fps (=frames per second) + additional re-timing the slow-motion is (in this case with 3x post re-timing) 1/12th of the normal speed. Gives a cool dynamic to the motion picture :-)
The recordings where done with this cameras ability to record a short sequence @ 100 fps. It buffers 6 seconds @ 100 fps to memory and then record the frames at normal 25 fps to tape which in return gives a 4x slow-motion with actual frames (no frame-blending nor pixel tracking). This results in a smooth non-blurry slow-motion often only seen done with high-end special cameras, although the sacrifice here with the FX1000 is a bit of quality (more noise/ lower resolution) but fully usable with good lighting and post-correction.
In addition the clip is digitally re-timed in post to give it further slow-motion using complex pixel tracking.
Pixel tracked re-timing differs from frame-blending in the way that each pixel is motion tracked to produce motion vector. An entirely new frame is created based on this analysis. Frame blending mixes simply two (or more) frames together to give the illusion of a new frame(s).
With pixel tracking the slow-motion becomes much more smoother without the characteristic blur one will get from frame-blending. The technology also offers the ability to remove already present motion-blur, or to add new one to make it look more authentic. Though, for optimal result the target object could be masked out to reduce artifacts from mis-interpreted pixel movements such as objects moving different ways or a static background (as in this video - look at the blinders and you'll see artifacts).
Recorded @ 1080i (HD). Down-scaled to 720P for this demo.
Re-timer from RealViz (aquired by Autodesk and no longer available as a stand-alone software). Edited in Premier Pro.
UPDATE: How to enable slow-motion recording in the FX-1000
See the video-version here:
http://www.youtube.com/watch?v=Z-9TtnQG9VY
There are two ways to enable this:
First one is to go to the menu of the camera. Select the CAMERA SET menu and make sure progressive is off (slow motion recording does not work with progressive in this camera).
Find the menu entry SMTH SLW REC and select it. In the next menu you can select how to record, before, after and middle.
Personally I use before so I can hit record button when I have viewed what I want.
Now press Execute to invoke slow motion recording and the hit the record button to actually record a sequence of 6-7 seconds (which then will be extended 4 times).
When hitting execure you will notice the camera is preparing. What it does here is to fill it's buffer so you can record "past" (if you ie. selected Before-metode).
Now the other way and probably a more convenient way is to assign SMTH SLW REC to a user button.
To do this go to the menu again and scroll down to the bottom and select the "Other" menu.
Select ASSIGN BTN and then chose which button you want to assign the slow motion recording to. In my camera I selected ASSIGN2 (the middle button on the side).
Select the assign you want and click.
Now you can scroll through the different functions till you come to SMTH SLW REC. Select again and you're ready to use slow motion recording at the hit of a button.
To stop slow motion just hit it again.
That's it :-)

Hi, I have a couple of questions. The first is how do I capture slow motion footage, is the same that if I capture normal footage? I´m asking this because in the settings of Final Cut to capture footage it only has the option of using normal fps, like 24 fps, 60 fps, etc.
The other one is if I can use the Final Cut application for changing the duration of a video clip without loosing quality or I need any of the programs you mentioned. I have Motion, can I do it with this program? Cheers.

@ospiis In this camera you will need to enter the special slow-motion mode (please see my other video on howto). What happends then is that the camera enter a special internal mode which you cannot access outside the camera, to capture what it sees @ 100 fps (120 in US models) and when you initiate the recording in the camera it transfer this buffer as a 25 fps (60 in US) stream to tape so that the actual video will be 25 fps. This is then transfered as any other video.

@ospiis To retime such a sequence you can of course use Final Cut, Premier etc., but these slow-motion technique uses poor techniques such as frame blending etc. To get a smooth slow motion you will need special software that uses motion vectors/pixel tracking and is therefor able to simulate that missing frame much more realistically then with other techniques. Try f.ex. Twixtor or even VirtualDub (which is free).

so this camera works on tape............
(great video though)
any idea how can i sync the videos into my computer ?
p.s i'm using a MACBOOK .
thank you.

@halfhourof8MuSt Yes, it stores its digital signals on tape, but you can also attach a digital recorder to this camera (flash memory) as an option. To transfer video you simply attach it via the FireWire port connected with a cable between camera and computer and you can transfer the digital signal from tape to your computer with software like Final Cut and similar for further editing.

@Optisoft are the compact flash recorders really that benefitial, cuz their quite expensive. Are they worth it?
shnizzlebizzle4rizzl 1 year ago
@shnizzlebizzle4rizzl IMO it depends. If you work in a busy environment where things need to happen fast I think a flash recorder will pay off as the transfer to disc is much faster than transfer from tape (and since one can records to tape simultaionously you can directly archive the tape for backup). Otherwise perhaps not, it probably becomes more a nice-to-have device.
