MC110 Lesson 9: Creative Retiming Effects

Which kind of motion effect displays a single frame from a clip or subclip for a duration you choose?

A Freeze Frame

Which kind of motion effect speeds up or slows down video at a constant speed?

A motion effect motion effect

What kind of motion effect uses keyframes to vary a timeline segment’s speed over time?

A timewarp effect

Where in media composer will you always apply timewarp effects?

In the timeline

How do you build a variable speed effect from scratch?

By adding timewarp to the timeline segment

Where do you find timewarp presets?

In the effect palette under the timewarp category

Which two time warp preset effects ramp the speed from a freeze frame to the clip’s native speed or from the clip’s native speed to a freeze frame?

0 to 100% and 100 to 0%

Which timewarp preset effect by default, uses a segment's first frame to freeze the entire segment?

Freeze Frame

Which timewarp preset effect reverses a segment's motion (-100% speed); for example, a scenic shot that zooms in will zoom out once reversed?

Reverse Motion

Which timewarp preset effect ramps from ~50% (approximately) to roughly 200% at the segment's midpoint and then back to ~50% at its last frame

Speed Boost

Which timewarp preset effect ramps from 100% to about 50% at the segment's midpoint and then back to 100% at its last frame?

Speed Bump

Which timewarp preset effect trims speed rather than content when performing a ripple or dual-roller trim?

Trim to Fill

Why is timewarp a neutral effect?

You’ll see no change when you apply it

Where do you go to customize a timewarp effect?

The Motion Effect Editor

What pop-out graphs will you use inside of the motion effect editor to customize timewarp effects?

Speed and Position

What are the two axis on the timewarp speed graph in the motion effects editor?

Speed and and timecode

How do you change a keyframe’s speed value and position in time?

Option dragging the keyframe

How do you isolate a keyframe’s movement and move it earlier or later in time?

Hold Shift option

What are the 4 kinds of interpolations?

Shelf, Linear, Spline, Bezier

Which keyframe interpolation holds a keyframe’s value until the next keyframe — causing the speed to jump instantly from one value to another?

Shelf

Which keyframe interpolation creates an abrupt, continuous speed change between two keyframes, removing the gradual acceleration out of and deceleration into keyframes.

Linear

Which keyframe interpolation creates an automatically calculated natural ease-in and ease-out around keyframes

Spline

Which keyframe interpolation lets you customize how gradually or abruptly speed changes occur around keyframes by dragging an active keyframe's bézier curve handles?

Bezier

What is the acceptable default render type for time-warp effects?

Both Fields

If you’re working with interlaced footage what render type is recommended for keyframed timewarp effects?

Blended Interpolated or Blended VTR

Which timewarp effect render types require you to render to see results (these options work best on high-resolution film projects and can cause movement to look odd in lower-resolution footage.)

FluidMotion draft or FluidMotion

What function can you use to change what frame in a segment a freeze frame happens on?

You can change the source anchor frame

What effect would you use if you want to lengthen a shot but it doesn't have enough handle? Or what if you cut the exact content you need into your sequence, but it doesn't quite fit with the music's timing or underlying narration?

Trim to Fill

What kind of keyframes have the start and end keyframes become closer together (contract) or further apart (stretched) as you trim?

Elastic keyframes

Which kind of keyframes have the keyframes remain in place (fixed) as you trim. That way you add or remove content as you trim and speed remains unchanged?

Fixed keyframes

How does the Fit To Fill edit differ from Overwrite?

Fit To Fill uses 4 marks while Overwrite uses 3

When you add the Reverse Motion effect to a Timeline segment, what does Media Composer automatically set the speed to?

-100%

You increase a segment’s speed and suddenly the movement freezes at the end of the segment. How can you fix this?

Monitor the Position graph while decreasing the speed until the line crosses the Position graph’s right edge

Fill in the blanks: To change the Source Anchor Frame, add a __________ at the new location, click the Set Source Anchor Frame button, and __________ the original keyframe.

Keyframe, delete
