What version of Premiere?
Have you installed all applicable updates?
I think this was a CS6 bug that was resolved in CS6 updates.
I can't advise regarding CC7.
Will the media browser bug be fixed? It's been over a year.
Media-Browser CS6: Thumbs are displayed repeatedly (Photo and Video)
Media Browser jumps to start
Sorry, I forgot to include details in the post.
Premiere Pro CC 7.0.1 fully updated
iMac 3.4GHZ Core i7
32GB 1600MHz DDR3
Footage is on a drobo 5D connected with thunderbolt
It's a known bug that I think may have been fixed in 6.0.3 but somehow returned for 7. Please let Adobe know it's more than just a 'nuisance' and it needs correction - again.
Thanks Jim, I'll add "an editing suite that works as advertised" to the wishlist. So much for speedy browsing of EX3 footage. Funny though, all other footage loads in the meadia browser without issues, only the EX3 footage has problems.
