Stop motion frame rate

Hello,

I'm trying to do a stop motion film and I have a few questions about frame rate. I'm using iMovie 6.0.2 on OS 10.4.7.

1. The shortest possible duration I can put on a photo is 00:00:01. I've heard it said in this forum that the last two digits stand for frames per second, but that doesn't make sense, seeing that a higher number of frames per second would have a quicker duration, but the higher the number in the last two digits, the longer the duration. I assume that the final 01 stands for "one tenth of a second," or about 6 frames per second. Normal stop motion does app. 24 frames per second. Is it possible to set the duration of photos to something near this?

2. If that isn't possible, a friend of mine suggested simply putting the photo duration to 00:00:01 (6 frames per second, if I am correct) and fast forwarding the video at 4x. In order to prevent the music and sound effects from also being fast forwarded, she said to try saving it at 4x and exporting it to quicktime or something, then import it back to iMovie so that the 4x speed becomes the default and reads as 1x. Can this be done? Thanks.

00:00:01


That refers to one single frame. The notation is minutes:seconds:frames.

I prefer to import stop motion still images via QT Player Pro. Just name to stills so that they sort as desired. Then open them as an image sequence in QT Player Pro with a desired frame rate, and then export them as DV.

As another option, you can also tweak the Ken Burns effect to import the stills as a desired frame rate:

in addition to Matti's excellent advice...


iM works with 30 or 25 frames per second (NTSC/PAL), not 24fps, that is movies, film, cinema....

so, a 00:00:01 is a 1/30th of second in your country...
most animation studios don't ainmate every frame, the old Disney's were done 1:1/1:2, the manga styled modern asian stuff is done 1:5... or less, adding tiny disolves between each cell....

for creating stop-motion movies, have a look at Boinx' iStopmotion, a tool designated for .. ehm, stopmotions... 😉


helpful?

I guess you could get a similar effect by 1st doing the animation using a slightly slower frame rate. Then use JES Deinterlacer to convert it to the final frame rate tweaking its Blend mode:

"You get special fast-motion effects by mixing JES Deinterlacer's "Blend" or "Telecine" and "Progressive" or "Interlaced" output options.

Different material and different fast-motion ratios may need different options so run a test and see what you like the best.

As a general guideline the Blend & Interlaced is very nice with somewhat fuzzy image and smooth motion (several interlaced frames are blended in a single frame).

Blend & Progressive combination is may also be nice because it makes the camcorder pans and shakes more fuzzy (several frames are deinterlaced and blended in a single frame).

Telecine & Interlaced is crisp but also jerkier (every Nth interlaced frame is preserved). Telecine & Progressive may often be too jerky (every Nth frame is deinterlaced and preserved)."
