Matching Audio To Video Playback Rate Preview.

[dj smith] “i know you can right click on the video stream-then click properties and adjust the playback rate there. the only thing is that it only does it for the video stream. when i use the yellow arrow in the main window to adjust the rate it changes both the audio and video rate automatically.”

You can do exactly the same thing with the audio – right-click, properties, and adjust the playback rate. An easier way to do this is to hold down the CTRL key and resize the event. This will adjust the playback rate of both the audio and video.

hi jeditdv. thanks for responding so quickly. so i tried out holding down CTRL and resizing the event. that worked, but it only stretches it up to a certain point and doesnt lower/raise the pitch of the audio (which i want). i want to get it slower than that stretch limit. also, i tried using a velocity envelope, which works for the video but it leaves the audio in its original state, so essentially it becomes a slowmotion video with the audio playing normally, hence no syncing. how can i get the audio to match the changes made in the video’s velocity envelope? what i want my video to end up looking like is the way it plays when i simply load it up and adjust tha normal playback rate in the main window to .37 and play it. the video and audio are both slowed waaaay down automatically and in sync and the pitch of the audio is correspondingly lowered-all to the way i specifically want it to end up looking/sounding like. is there a way to save the video/audio in accordance with the the value of the normal playback rate in the main window and the way it plays back?

thanks so much. 🙂

As for going slower, stretch it out as far as it will go, render it, add the new file back to the timeline, and do it again.

The limits for CTRL-resize are .25x to 4x.

For the pitch changes, you might right-click the audio, choose Properties, change the “Time Stretch/Pitch Shift Method” to “Classic”, and then adjust those settings as needed (i.e. you might need to check the “Lock to Stretch” box).

cool. i think i got it now. just a few more questions….

is there a way to display the amount (between .25x and 4x) that you are resizing as you CTRL-resize events? for example, if i am CTRL-stretching an event i would like to see by how much, numerically (.25x-4x), i am/have stretched the event as it is happening.

when i use the velocity envelope for the video and add several altering playback rate changes (points), how do i get the audio to match those changes accordingly? i.e get the audio to slow down/speed up in sync with the video as it is playing back.

thanks. appreciated. 🙂

Yes. Look in the View menu for the various options that can be turned on. I believe you want “Active Take Information” after which the % change will appear in the audio track.

im using vegas 4 so “active take information” doesnt exist in the view mode. ive looked for something that may be similar to no avail.

anyway, one last thing.

when i use the velocity envelope for the video and add several altering playback rate changes (points), how do i get the audio to match those changes accordingly? i.e get the audio to slow down/speed up in sync with the video as it is playing back.

thanks!

[dj smith] “im using vegas 4 so “active take information” doesnt exist in the view mode.”

You are correct. In earlier versions of Vegas it was under Options – Preferences.

[dj smith] “when i use the velocity envelope for the video and add several altering playback rate changes (points), how do i get the audio to match those changes accordingly? i.e get the audio to slow down/speed up in sync with the video as it is playing back.”

You don’t. There is no velocity envelope for the audio. What you CAN do: split the clips as appropriate and use the CTRL-Resize which will speed up or slow down both the audio and video at the same rate.
