I'm attempting to track a lenghter clip and am receiving this error in both versions of after effects 'unable to obtain dynamic link video source'.
although the initial sequence was a dynamic link from Premier I have also attempted to directly import into after effects and track , as well as trimmed clip cosniderably shorter, only to result in same error message.
I'm running an iMac Pro 3 Ghz Intel Xeon W, 64GB of RAM and 16 GB of VRAM Radeon Pro Vega 64, OS 10.14.6
The clip is Mpeg-4 50Mbits. approx 30 seconds in length.
Could indicate a permissions issue with temp folders or running out of disk space. Hard to tell, but you might want to look into that, since these processes produce a ton of temp data, duplicate clips and caches.
thank you for suggestion. i imported directly and when i split the clip i was able to track the partial scene beautifully without issues once. since that successful partial track i have been unable to duplicate that process. the error persisting no matter how footage is; imported, duration of footage, type of codec or version. of after effects.
