Real-time Frame Rate Shifting Software

[Koroush]

Hi All,

I would like some information on a software or hardware that will
perform real-time frame rate transformation on a video stream.

I have a NTSC video, which I captured into a file. I now like to play
back this video with various frames rates by hitting a key, or turning
my video editing knob in real-time. The original video can be
captured at 30fps. I like the output to change real time between the
following frames per second: 30 (1:1), 25, 20, 15, 10, 5, 2, 1, 0.5,
0.1, 0.05 (1 frame every 20 seconds)

I would like to know if the is a simple piece of software that I can
buy to do this on a PC preferably using .avi files. Otherwise a Mac
or any other software is okay. If you are willing to write me such a
software that is great, please contact me.

Koroush: Just about any good video editing program available today can
alter the frame rate on playback, encoding. Check out the downloadable
demos at http://www.sonicfoundry.com, and http://www.ulead.com. Adobe
premire does the same, but as of yet, no downloadable demo. FCP on the MAC
likewise.

You should be able to do this with any DV-capable editing software.
Just set up a timeline with duplicate clips of the video, one at each
speed, and then scrub the appropriate clip in real-time. Most software
will duplicate frames rather than interpolate pixels for slow-motion,
but it sounds like that is what you want anyway.

Thanks for your replies guys,

I downloaded Sonic Vegas 4.0 and tried to see if it would do what I
wanted, but I wasn't successful. First of all It plays back
everything at preconfigured framerates as per NTSC or Film, etc. So I
wasn't able to dynamically change the frame rate as the video is
playing back. I tried to play with the rate control, but that just
slows down or speeds up the film and stretches the time as well. I
don't want the time stretched, I just want frames skipped.

Dan suggested that I replicate the movie and change the playback rate
and switch between the versions at different frame rates. I haven't
been able to set this up. How can this be done, or is there a simpler
way?

thanks very much again for taking the time to better explain your
answers.

I think Pinnacle Studio 8 can do this. There is a feature, which is found
in the time settings for a clip, it's called strobe, and you can specify how
frames are displayed without changing the actual time length of the video.

It sounds like you want to take 30fps NTSC and make it look like its only
25.. 15 .. 10 fps etc etc..
If so, the "Posterize Time" filter in adobe premiere does exactly that, you
just apply it to a clip, tell it what frame rate you want to use and it
should play it back as if it was at the frame rate you specified. I dont
know about other editing software but I'd assume some will have a similar
feature too.

Studio8 has the simple to use stroboscope.
It can be found with the slowmotion.
