Velocity Envelopes offer an even greater range of speed change than changing the Playback Rate or CTRL-Trim. The audio waveform stretches out, and the audio is now slowed and synced with the video. CTRL-trim the right edge of the audio event and drag it to the right until it snaps with the end of the video event. The length of the video event is now doubled, but the entire video clip is now displayed. With Ignore Event Grouping still activated, trim the right edge of the video event to the right until it snaps at the loop point. On the timeline, the video event has not changed length, but a wider wavy line is displayed on the video event. Type a value of 0.500 into the Playback Rate, cutting the playback speed in half. Drag another instance of the same video clip to a later point on the timeline. ✓ The process works for slowing video as well, just in reverse.
We’ll explore a bit more about CTRL-Trim in a later step. As you trim, the audio waveform compresses, and when it’s snapped into place, the audio is sped up and is now synced with the video event. Then, holding CTRL, trim the right edge of the audio event until it snaps at the right edge of the video event. Select the video event and trim the right edge inward until it snaps at the first loop point. First, trim the video so it no longer repeats. Or you can conform the audio to the video.
The video plays back at 4x speed, but the audio plays back at normal speed and is not synced to the video. Click the left edge of the video event and press Play. The audio did not increase speed and VEGAS did not loop it. ✓ Note also that the audio event is unaffected. If you slow the playback rate, the wave becomes much wider. The more you increase the playback rate, the tighter the wave becomes. Within the video event, there’s a wavy line, indicating that the speed has changed. It did it three times, and as a result, the video plays four times in the span of the video event. The 4x speed increase means the duration of the video is now ¼ of what it was, but because the video event did not change length on the timeline, VEGAS Pro looped the media back to the beginning. The video event has not changed length, but it now has three loop points. On the timeline, note three things about the video event. 250.Ĭhanging the Playback Rate, you can speed up or slow down the footage by as much as 4x.Ĭhoose 4.000, speeding up the Playback Rate 4x.
The maximum speed value allowed is 4.000, or a speedup of 4x, and the slowest value allowed is. For example, 2.500 speeds up footage 2.5x, while .250 cuts the playback to one quarter speed, or a 4x slowdown. For noticeable speed changes, an increment that small could take all day, so just type in a number. This is useful if you want to make very subtle changes in speed, such as when you’re using PAL-framerate footage in an NTSC-framerate timeline, and need to conform the footage just enough to fit. The playback rate changes in increments of. ✓ Click the up or down arrows next to the Playback Rate value.
At default, the Playback Rate is 1.000, or normal speed. In the Properties box, note the Playback Rate toward the bottom. When the pop-up box asks if you want to conform the project properties to the media properties, click Yes. This method makes it especially the kind of smooth slow-motion we described above, as we’ll see in a moment. The simplest and most precise way to speed up or slow down motion is to change its playback rate in the Media Properties.
