Frame question

readw wrote on 1/23/2003, 7:28 AM
I am new to VV3 so please be kind. I have taken a frame from a clip and I now want to extend that frame over a 50 frame space and then I want to zoom in starting from frame 1 to frame 50 to create an effect moving in on the object of a 50 frame period. The space created around frame 1 onwards will be black. Could someone please step me through the process or refer me to a tutorial on how to do this.

Thanks

Warren

Hi Warren,

Please help me understand a little better...


Over a duration of fifty frames you wish to zoom-in to a detail in a still-image?

Do you also want a black border around the zoomed-in image to increase over the fifty frames, or did you mean the video before and after the still is black?

*If* I understand correctly, you want to show a black picture with a smaller object somewhere in the frame -> then you want the object to get larger, perhaps filling frame # 50. *IF* I'm correct...

You could do this using one of the transition FX, tailoring it to your purpose; basically you're dealing with a transition from a pure black clip to one showing (or at least starting with) your static frame.

Another method would be to create 50 stills; I've done similar when I wanted higher quality resizes or special P/Shop type effects.

And another would be to import your still onto the top track, have a black video below it, and adjust the pan/crop (& optionally track motion) for the image clip. A mask might help soften things up a bit.

Remember to select project size in the preview window -> then I normally select best quality (though this may be unecessary) -> then click the floppy disk icon to save your jpg image. I also will usually tweak any frame captures like this in an image editor as a video frame is often not the best quality still -> deinterlace the image for one, and usually soften it a slight bit to help eliminate any jittering if the output is going to be interlaced. For progessive I'll do the opposite, cleaning and sharpening.

Finally, have had success once or twice using more then one frame for the stills. You can take a very short clip & stretch it, or just space the frames out. One of the biggest chores with compositing is getting things to match the rest of your video, to look natural. Allowing some movement, even if only noise, can help the transition from static to full motion [disect broadcast footage if nothing else and I think you'll see there's hardly ever anything totally static, even during fades and other transitions.]

Thanks very much for the responses, I will give these options a try - In Premiere I can do this quite easily by simply by using a command that I forget the name of to copy the frame and make it 50 frames long and then using the motion command with a black background to zoom in. So rather use Premiere and then import the clip (the lazy way) I want to get a full understanding of VV, and get away from Premiere as much as possible. Thanks

I want to start off with the image at 0% of its orginal size and zoom in ending up with the orginal image at 100%. This pseudo clip needs to be 50 frames long. In Premiere I can do this by using the motion command.

Cheers

Piece o cake Warren,

Place event in timeline
Drag event's upper-left corner "Fade-handle" to the right until it says 1:20
Drag "zoom-in, center" transition from transitions window and drop on event's fade.
Done.

Couldn't you use pan/crop for this?
PLace frame on timeline, drag to right edge along timeline to fit 50 frames.
Go back to frame #1 on timeline. Open pan/crop, set keyframe, reduce frame-size to nothing and place at centre of screen, finally set a keyframe at end of pan/crop keyframetimeline and enlarge frame to fill screen (- make sure smoothness is set to 0). done...no?

well just a thought...

Hi PDB,

Track motion (TM) might be easier than pan/crop (p/c)... Same process tho.

TM is usually better for sizing moving the image around inside the frame, p/c is usually better for moving the frame inside the image.

Warren,
This sounds like a piece of cake, but what is it with the black frame? Do you want the zoomed clip to change size as you zoom, is that it? You'll get an answer as good (and kind) as your explaination of the problem.
