Audio velocity??

Rory Cooper wrote on 2/4/2009, 9:23 PM
I have this project where this whole “imagine” thing is happening with ghostlike text and visuals etc..

on the video on different tracks I have the visuals slowing down and holding at different intervals using velocity envelopes and keys

the audio needs to slow and hold for a fraction and then pick up pace “or pitch”

how do I key this thing??

Thanks guys

Rory

Sound Forge includes an effect called Pitch Bend which can do for audio what velocity envelopes do for video. However, there is no way to sync it with the video velocity so it will take a lot of trial and error and jiggerypokery to get the result you want.

On the last video I did there was a piece that had to slow to a stop like a record on a turntable that was unplugged then pick up again as it was plugged in. But I ended up doing this in Adobe Audition because I couldn't figure out how to do it in Vegas..... if it can do it at all.

Thanks guys

I would have thought that this would be a common problem. Audio pause for emphasis is common, how are the other guys handling it in Vegas?


often I just split the audio and stretch the part that I need but this takes time. I need the audio to come to a grinding halt : not drawn out: and then hit off at normal pitch

I have Audition will give it a go…so I suppose I would put some markers down count the time between markers in Vegas
And try to match in Audition..drop in Vegas and hope for the best

thanks once again

A user on the Cow Vegas forum posted a link to a free VST plugin called TapeStop (link is to a zipped file).
Apparently you'll need to automate it twice - once for the slowdown, and once for the speedup..
I haven't used it but it said it worked great for his needs.

Cool plugin - thanks for the link.

I can hear its effect in realtime, when I engage it while playing an audio clip on the Sony timeline. But I can't figure out how to SAVE the slowed-down/sped-up audio. No clue in the readme file that comes with the plugin, unless I'm just missing something...

Wouldn't you render the finished output ... just as with any other effect?

I should have mentioned in my first post that yes, I did render the relevant clip. In the preview timeline, I could hear the slowing-down; in the rendered clip, there's only silence.

Perhaps this has something to do with "Audio FX Automation", with which I'm not very experienced... I simply tried rendering the same clip that I heard affected in the timeline, with rather confusing results.

Must be missing something...

Thanks Mike

OK but I am missing the boat…it’s a dll file so what do I do with the dll?
It doesn’t run as a script so how do I apply the dll in Vegas?

Its good news to hear that its working as I would use this often

Rory, it's a VST plugin so drop the dll into your Vegas VST folder, wherever that may happen to be.
In my case, it's C:\Program Files\Vstplugins but it can be anywhere you want.
Then go Options - Prefs - VST Effects in Vegas to refresh the list.
Once a clip is on the timeline, click the Track FX icon on the Track header, choose this FX from the VST folder and start experimenting with it.
Please note that I haven't used it myself yet.
I just remembered reading about it and thought I'd pass along the info.

Shot Mike!!!

It’s grafting….after I click on fx automation the keys become available…just need to work out how to effect them and then render

This looks very useful indeed just what I am looking for

Thanks once again

If any one out there has any experience with this I would really appreciate a few pointers

Thanks
Rory
