pan/crop vs. track motion zoom

L8R wrote on 7/23/2008, 7:01 AM

This may be a stupid question but ...is there any quality difference if you zoom in using the pan/crop feature over the track motion zoom or vise versa?
I am shooting in hdv 1080i. my workflow is the 1440x1080 60i template.
I've noticed that if I zoom in with the pan/crop feature to either do a "fake panning" motion or to crop something out. The video seems to be a bit degrated or fuzzier.
I know this is because I am digitally altering the video.
Is there a reason for having two different methods of doing this as you can essentially do the same thing with the track motion with the key frames. Is one better then the other for such a thing?

Just a follow up on my related confusion:

To begin with, the project properties is the HDV 720 template. 16x9.

1. Go to pan/crop, match output aspect, no problem.

2. Go to track motion, and it is already 16x9. Good to go.

3. Make a child track, then go to parent motion, and its a box. 720x720. Match output aspect nothing happens. Manually set the width to 1280, and it stretches the video.

Why is this?

The reason it seems to mater: if you have a keyed out background, and you want to move in on the subject and background at the same time, you can use the parent/child relationship. But if you render out for TV aspect ration and want a letterbox, then that part of the timeline where you zoomed will come right out of the letterboxing.

This thread is a wealth of information on a topic about which I was unclear.
Another one for the Bookmark list!

damn dude now I'm confused....lol.

Well I learned what I wanted to know...

Hey and as a heads up if anyone missed the post in the vegas pro video forum about 1/2 off mercalli image stabilization pluggin. You should. for 59 dollars it's yours.... if you ever had a good shot ruined by a jitter or shake in panning or zooming this stuff steadies it... It's brilliant.
check out the link it's great.

Hi!

Just wanted to ask if anyone could help.

I have high resolution maps (20x20K pixels) and I want to follow my route on this map. I want sometimes to zoom in, sometimes zoom out and then in the end show the whole map. Because of this i had to use two maps (one downloaded with the low zoom - borders of countries etc.; and second with higher zoom - cities, villages, ...) and during the video I wanted to blend these two maps between (according to actual zoom in video).

I thought I could use track motion, but it - as it´s said here - totaly decrease the quality of map. And in pan/crop its almost impossible to set these two maps (both of it has different sizes). Do you have any idea of any tool/addon or even other graphic program where I could create this?

Thank you.

did you try to use Pan/Crop's keyframe using a single map only?

Cibule wrote on 8/2/2017, 6:18 AM

Yes I did, but its either too much detailed and I cant see borders of countries when I zoom it out or not enough detailed when I zoom it in at some interesting parts of route.

I will probalby try to cut and compress the pictures of map to the same sizes and then use the same atributes of PAN/CROP on it and then just cut when I want large and cut when I want smaller map.

anyway, thanks for soon response
