Track Cropping at DVinfo.net

Anyone know if it's possible to apply a crop to an entire track rather than just a clip?

track motion but generally it's better to apply pan/crop to clip. resolution holds better however if you need to crop eveything the same you COULD crop 1 then 'copy'. Highlight the rest of the clips and then 'paste event attributes' but keep in mind this will paste ALL attributes that were on the first clip and copied so you'd want to do the cropping first.

Thanks Don, I'll give that a try.

Out of interest why would the resolution be better in crop/pan than in track motion?

Track Motion uses the resolution of the video frame. Pan/Crop uses the full resolution of the original clip. Therefore if you have a hi-res picture, you could be zooming in on the full resolution when using Pan/Crop. With Track Motion and that same image, you'd be zooming in on the video frame (i.e. 720x480 with NTSC DV)

How about bringing back as a Nest and applying Pan/Crop to the nest?

So for the pic-in-pic look using the pan/crop would be the better than the track motion. The reason i'm asking is, i am going through the sony production work book and it mentions to use the track motion for pic-in-pic. The way i see it either will work or am i wrong. Please set me strait.

Thanks
John

But presumably if your source is full resolution video it would make no difference whether you used track motion or pan/crop? In other words, this is only a factor if your source is of a higher resolution that the frame size you are working in (eg a high res still). Have I got that right?

Is this Preview Reso or final Render Reso? I am not clear which of Edward's statements is applied to either Preview or Render?

John, for PIPs, Track Motion is fine because you're not zooming IN on an image - instead you're zooming OUT.

Ian, that would be correct. If there's no more resolution either would work the same. I still prefer Pan/Crop for the cropping purpose, though.

Thanks all. I guess that was the point in all this. That if you are zooming out there was no loss of resolution. However if I were doing a photo job or something then the pan/crop would be the best option for putting movement to the stills.
