Slo-Mo HELP

[Jay A. Kelley]

My issues are not with RED.. The Slo Mo here works fine. My issues are based on inexperience.

please answer the following:

I would like to shoot a slomo test and then use After Effects to double the frame rate again. I have see this done successfully.

So:
What should the BASE frame rate of the camera be for best possible results.
What are the steps in AE? Is it simply the Time Stretch command, or something else.

Any help or advice in this area would be good

i do know about increasing shutter, so that's covered.

what framerate are you trying to achieve??

Long story short, best result in AE are even doubles of your source footage, so if you want final to appear like 96 fps, shooting source at 48fps will give best results... if 120 fps is final desired, shooting source at 60fps would give best results... etc....

That being said, AE has a filter/time effect called "timewarp" which works very well, and essentially creates "tween" frames between your source images. To use it, simply import your footage at 24 fps (assuming of course your final output will in fact BE 24fps...), and apply the effects/timewarp effect...
the default settings automatically double the theoretic fps (the default setting plays your footage at 50%) but this is completely adjustable. And you can do any percentage, faster or slower, and get some astounding results... even doing animated ramps, etc.

On your first time through, just make sure you have these two initial settings picked:
choose the "method" as "pixel motion", and the "Adjust Time By" to "Speed"

After that, adjust your speed setting, and have fun!
(Be forewarned that this filter can require a lot of tweaking, and depending on the source footage, you may seem some bizarre artefacts, after inital processing, such as image ripping, tearing, blurring... but once you get familiar with the effect, you can minimize and often completely remove many of these... )

Also, please note that this effect is a processor and RAM hog, so expect longer than usual render times...
Hope this helps!

Motion has a optical flow slow mo just like flame,
It's fatser to render, smoother finish. AE is still good, but Motions seems just that little bit better.
120 frames per second out to 240 quite easily.
