3D Camera Tracker Duration?
Posted by Ben Lewis on May 17, 2016 at 3:10 pmHi, I am using the 3D camera tracker within AE and want to know if there is a way to specify that it only analyses for a specific set of frames? I think it references the original clip? This seems to take far too long. I’ve tried reducing the timeline work area but that doesn’t work. Is there any other way other than cutting the footage myself?
Thanks!

May 17, 2016 at 3:28 pmmain problem can be is video files are compressed 99% of chance of failer is tracking application fails to detect pixels so what u do is make jpeg sequence out of that video and re import the jpeg sequence and set the frame rate on that imported jpeg sequence so it matches the original frame rate then try tracking it again it will work.
just add video to render quick and set option as jpeg sequence rather then avi.
then close project reimport the jpeg sequence it wil work , just set the frame rate once you imported it.

May 17, 2016 at 3:30 pmWell, um, I don’t know if that is very practical, though yes, you could convert your footage to something else that would be easier for AE to track/render, but again, it depends.

May 17, 2016 at 3:35 pmThanks for your suggestions. The conversion option seems just too long winded for my project. But I’ll try splitting the layer. Thanks

May 17, 2016 at 4:26 pmWhy would you want that? Maybe specify what you’re trying to accomplish, and we can help you find a solution. If you’re only trying to track the camera for a short shot, why not trim the clip to only the section that you want to use?

May 17, 2016 at 5:37 pmHey, Im currently trying to get my head around the 360 workflow and i’m struggling. I have a system called Skybox Studio and i’m tracking footage within that. It’s one long take and I tried camera tracking that but I seemed to track the entire clip. I have cut the section and I am now trying on a shorter clip. I’ve been following a great tutorial from Mettle https://vimeo.com/145580525 but Im finding it tricky.
Thanks for your support.

December 3, 2018 at 9:27 pmYes . Double click layer. You will see a timeline . On that tool bar beneath the time line there is a in and out point. Set them. Then ctrl shift D will split the layer right where you need to work with . Then camera track thst portion. Rinse and repeat for other portions .
