Week #13: Time Stretch, Time Remap, Time Warp

Three ways to work with time:




HOW TO:

TIME STRETCH alters the duration (and therefore speed)
BUT, it does not let you animate the retiming itself, that requires TIME REMAP, or TIMEWARP

HOW TO:
locate the icons on bottom left of the TImeline
In/Out/Duration Stretch columns

1. Place the CTI in the Timeline frame
2. Change the Stretch % (Change the Stretch value from 100% to 300% to slow or stretch it out)
=============================================================

TIME REMAP
This sets two Time Remap keyframes
the final keyframe becomes the HOLD keyframe.
you can then scale (pick up the clip and drag it down the timeline) the layer length beyond the last frame.

Select the layer, and apply TIME REMAP,
Layer > Time > Enable Time Remapping
or COMMAND & OPTION & T
move the keyframes together to speed up the area inbetween the keyframes.

EXAMPLE: Place the keyframes together at the beginning, and the video will speed through the entire clip, then hold on the last frame for the time after the second keyframe.
=============================================================

TIME WARP
Effect > Time > Timewarp
Usually used for slowing down ( using a value of less than 100)
TIP:
1. first apply TIME REMAP Layer > Time > Enable Time Remapping
(don't worry, TIME WARP will over ride the TIME REMAP settings)
2. then apply TIME WARP Effect > Time > Timewarp
3. reduce Speed property
4. Extend the length of the clip in the Timeline to accommodate the new ( reduced) time.

EXAMPLE: reduce Speed to 50.00, and drag out the clip

----------------------------------------------------------------------------------------------------------------

NOTE: may need to Preserve Frame Rate for nested clips
Composition Settings > Advanced panel and toggle Preserve Frame Rate When Nested
----------------------------------------------------------------------------------------------------------------

You can also FREEZE FRAME
Layer > Time > Freeze Frame
creates a similar effect as Time Remap at the CTI, when selected.
