Answers | 1. | Each frame of video is made up of two separate subframes called fields. | | 2. | For NTSC, the spatial field order starts with field 2, the even-number field. For PAL, it is the opposite: field 1, the odd field, is the first spatial field. | | 3. | Pull-down is a technique to temporally convert film footage to video footage and back again. | | 4. | Shake can read AIFF and WAV files, mix them together, extract curves based on an audio waveform, manipulate the timing of the sound, and save out the files again. | | 5. | You can change the timing of an audio file by first making sure that it is selected in the Audio Panel and then adjusting the Time Shift parameter. |
