Happen to me just now. Been using premiere and brinnos for years now without a problem.
Im using 12.1.1.
Quick solution I suppose is to batch transcode with mpeg Streamclip.
Is this on Mac? If so, sorry, this is no longer supported.
yes on a mac.
Any reason why?
It still seems to be a significant format no?
As I understand it, it has to do with the internal file structure containing QuickTime 32-bit 7.x code, which we can no longer support based on our partnership with Apple.
That said, there is always the potential for engineering to create a custom version if enough users request it. Do so here: Support AVI files needed in newest release... URGENT – Adobe video & audio apps
