Zooming with Pan & Crop question

TGS wrote on 5/9/2007, 9:09 PM
I'm fairly new to using this feature. Is there a way to increase the speed of a zoom smoothly. As if accelerating without jerkiness or steps of speed? Actually, I'll be zooming out from a close up and I want the speed to increase without noticable steps. I was going to do a search for this, but didn't know how to ask.
TIA

If you right click on a keyframe you can change it from Linear to Smooth. Now play with the Smoothness setting on the left - under Keyframe Interpolation - between 0% and 100"

If you set up a loop in the timeline you can watch the effect of each change you make.

TGS? Have you tried rendering, just to see if it is "smooth" enough first? Initially I use "Build Dynamic Ram Preview" over short pieces, just to confirm the "look" of my video?

Pete, I'm wondering if our friend here is referring to pre-render jerkiness, rather than the "smooth" zoom settings? But there again, I'm not sure?

Grazie, the reason I thought Smooth was to introduce some acceleration, and deceleration if required The actual speed reached depends on how far apart keyframes are, and increasing the Smoothness number (0 to 9.9) makes the ac/deceleration gentler.

Absolutely Peter. I agree. I want to be assured that this isn't a Preview jerkiness issue - yeah?

Yo, bro ;)

First, thanks for the answers. I didn't know about the smooth control. As I said, I'm new to this and never messed with zooming in this way very much. While I didn't try building a dynamic ram review, (I'm working with uncompressed AVIs and photos) I had already rendered a few versions and I could see the incremental steps. I'm trying to 'Zoom' out of the Universe, starting from Earth and I need to build speed fast. I'm experimenting with a logo and it can't last too long. I will give it a try if I can figure it out.
Thanks again.
