Camera FBX to use as base tracking and refine in PF
Hi,
Is it possible to import a camera fbx that has basic tracking data and use that to do a refine pass OR atleast use the starting position and track further? And is it possible to combine that with a Lidar scan in survey node? If so how do I do it?
Thanks.

Wow! You aren't kidding. The YouTube Channel is gone (at least as of this moment)! The only videos that seem to exist produced by TPF right now are the ones from the learn link or about 4 videos on their Vimeo account. I'm hoping this is just because there's a glitch with YouTube, and not that TPF has just nuked their videos. IMO this has been a long-standing issue. Many developers will go ahead and leave up older tutorials, even if the software has changed. This is great because there are often useful nuggets that still apply and most users can sort out the differences and keep working. TPF does not seem to have this view. There was a really old tutorial from the TPF that I would refresh my knowledge with every year or so because I used the technique it showed about that often so I always needed a refresher. When they cleared out the Vimeo channel, it was lost forever.
I haven't had time in a LONG while, but I've been occasionally creating tutorials https://vimeo.com/user167257849?fl=pp&fe=sh with the intent of trying to give more insight into how to gain more control with the app. I'd backed off because TPF has (had?) been putting out more and better content in the last few years. I'm hoping this hasn't come to an end. Maybe this will inspire me to try to get back into it.
