Slow MO and Fast MO

[pest22o]

Okay I've been hearing diffrent things on how to achieve the slow motion Effect I know you use a higher frame rate then in post run it as 24fps, no who wdo you achieve the fast pace action? you know those scenes whhere someoen is standing still and everything else moves fast, do us 24fps? and I heard you have to shange the shutter speed as well? anyone care to help me out on both slow and fast?

FAST MOTION: to be quite honest... i don't usually try to achieve "in camera" effects with the DVX. i have the first generation DVX so i have no overcrank feature. i usually try to keep all my footage at the same frame rate and shutter speed. to keep the look of all my footage relevant. then i do most of my fast motion tricks in after affects if you are referring to a stationary tripod shot and your subject is stationary in the shot as well... then shoot the background first for several minutes without your subject in frame then have your subject step into frame. then import both shots and layer them in AE and mask around the subject in affter effects. speed up the background and leave the foreground at it's normal framerate... i hope that helps. You could even check out barry's DVX book i hear he has all the specifics in regards to the best framerates and shutter speed formulas that the DVX can kick out.

There are some interesting tutorials on this in "The DVX Book" I would reccomend it. I'm using a DVX 100B by the way. I believe this work on the 100A also. Essentally, F1 on your DVX is 60i (in scene file settings you would set progressive to off). Many editing programs will not recognize 60i footage though. For instance, I use the adobe production studio. I capture the 60i footage in premiere (a 24p project) then put the raw footage in After Effetcs to slow it down. Put the Time stretch in AE to 250% and then export that at 24p and put it back in premiere. You will have flawless frame by frame slomo. These are the numbers for the perfect ratio, stretching to 250% is actually 40% speed. Search tutorials under overcranking, this is what its called. I don't know the numbers for fast motion, but thats also possible. Great results, gotta love the DVX!
