If the hand-crank effect results in footage that is too dark or too bright overall, you can offset that here. This control allows you to manually adjust the exposure of the footage, in stops. At values over 100%, the exposure effect is boosted - both the brightening and darkening effects. So in hand-cranked footage, slow moments go dark, and fast moments go bright, or "burn out."Īt 100%, the exposure effect is calculated realistically. In a real camera, when you slow the frame rate, you slow the shutter speed as well, and therefore let in more light. Advanced: Exposure InfluenceĪllows you to adjust the intensity of the automatic exposure effect that syncs with the speed changes. If you are processing multiple clips, it's a good idea to use a different Random Seed for each one. Small changes to this value produce big changes to the effect. At higher values, you'll see more variation in a given amount of time.Ĭhange this value to roll the dice and get a completely different random cranking pattern. This controls how rapidly the virtual camera operator alternates between fast and slow cranking. Handy if you want to transition between normal speed and the hand-cranked look within a single shot. Irregularity can be animated, so you can ramp in and out the hand-crankiness. if your Base Crank Rate is 20, and your Irregularity is 10, your virtual frame rate will vary between 10 to 30 fps. The minimum will approach Base Crank Rate - Irregularity fps. The maximum virtual frame rate will be up to Base Crank Rate + Irregularity fps. To put it another way, increase this value to get faster fast-motion moments, and slower slow-motion moments. The higher the value, the more pronounced the hand crank effect. This controls the maximum deviation from the Base Crank Rate. If you turn Irregularity down to zero, then Base Crank Rate is the sole determinator of the speed and exposure of the footage.īase Crank Rate can be animated, which means you can manually keyframe the crank speed of the virtual camera if you like.īut you don't have to, because of. The default value of 22 means that, overall, events will be slightly sped up from real time in a 24p comp. If your comp is set to 23.976 fps, for example, then a value of 23.976 (or, heck, even 24.0) means that the average crank speed will be 1:1, so events will play out at more or less normal speed.
This control relates directly to the frame rate of your composition. This is the baseline speed at which the virtual camera is "cranked," in frames-per-second. In the Effect Controls panel, you'll see Prolost Handcrank. In the Composition, I highly recommend turning audio Off for the Footage Layer.Īpply Prolost Handcrank by dragging it from the Effects & Presets panel onto the footage layer. you might have 59.94 fps footage in a 23.976 fps comp). If you need to, change the frame rate of the comp to match your editing frame rate (i.e. An easy way to do this is to find your footage in the Project panel, and drag it to the Create Composition button at the bottom of that panel. Under User Presets, you should see Prolost Handcrank.Īdd your footage to a new Composition.

Install Prolost Handcrank in your User Presets folder.That's part of the fun, but you'll likely want to check out the Tips section for some guidance on using Handcrank in your edit. It can work wonderfully when the source and destination frame rates are different - in other words, it can be used in conjunction with a frame rate conversion.īecause Handcrank radically re-times your footage, it can sometimes be a little unpredictable.
Handcrank works with any kind of footage, at any frame rate. It realistically simulates the speed and exposure irregularities of a hand-cranked motion picture camera. Prolost Handcrank is an Animation Preset for Adobe After Effects.
