Edit Keyframes Curves/Lanes to accelerate a Pan/Crop slide

PayasoPrince wrote on 9/10/2021, 8:57 PM

Hello all, 😃

I have a simple image track that I have sliding across the screen using the Pan/Crop Event.
I tried inserting a Velocity Envelope and added some points with different velocity %'s. However, the speed doesn't seem to be changing whatsoever.

So, my question is, are you able to use velocity envelopes on images that move through pan/crop key frames?

Any insight/assistance would be greatly appreciated!

Vegas Pro 19

Update: I've changed the thread title to be a little more specific to what I'm looking for.

Velocity envelopes are used to adjust frame rates not the location of the media in the frame. I suggest using key frames in the pan and crop window to change speed of pan and zoom.

My 2 cents

Here's one option. Once you're happy with your keyframed still image event(s), render the event(s) to a new track using a decent intermediate such as ProRes. Then apply the velocity envelope to the rendered intermediates.

Ack, I've been at it for hours. I believe what I am looking for is animating Keyframes with Curves/Lanes?
I just can't seem to find where to edit curves/lanes :/

I have created a slide effect with the Pan/Crop tool.
Under View > Envelopes > Track Key Frames is checked off, however I cannot see any of the key frames that I added with the Pan/Crop tool on my tracks timeline.

I've searched all over for the "Expand/Collapse Track Keyframes button" that I heard about through Google, but cannot find it anywhere.

I believe that the image below is exactly what I'm looking for? But I cannot seem to figure out how to get to this point:

Ultimately, I have a start point and an end point that I've created using the Pan/Crop tool. But I cannot figure out how to access the curves/lanes editing feature to make my slide accelerate and then deaccelerate.

I hope I did an adequate job explaining where I'm at. The hardest part about learning Vegas Pro is learning how to learn, if that makes sense.

@PayasoPrince As far as I know, the Curves/Lanes option isn't available with Pan/Crop. You need to use the keyframe interpolation settings for each keyframe to shape the path from one keyframe to another.

Use PIP fx to replace Pan/Crop.

Check out Vegasaurs tweener tool.

@PayasoPrince, It does seem that you may be using the wrong tools, but it depends upon exactly what you're trying to do. If you have a video/image and you want it to actually change location (e.g. an inset picture which slides across the screen), then @lan-mLMC has the right answer. Use the PIP FX instead of Pan/Crop. To change the velocity of the animation between one position and the next, then @Jack S has you on the right track: don't use Velocity envelopes (those are for creating slow/fast motion). Instead, right-click the keyframe and choose the velocity shape you want from the context menu.

Vegasaur is a great tool which I fully endorse, but for what it sounds like you're trying to do, you probably don't need it.

@gary-rebholz Now Pan/crop ( without keyframe curve ) can almost be replaced by PIP or some third-party plugins ( like Sapphire S_BlurMoCurve ) with keyframe curve. It is a good news. We can use PIP and S_BlurMoCurve to do all kinds of custom accelerated or slowed motion.

But the native 3D parent track motion/3D camera ( all tracks with 3D source alpha ) still doesn't have an alternative FX/Plugin to do custom accelerated or slowed motion. I think it is time to bring keyframe curve to 3D parent track motion/3D camera ( all tracks with 3D source alpha ).
