I've been using AE CS6 and Premiere Pro CS6 for the past year to edit videos shot using a combination of Canon 60D and Sony EX1 footage. I deal with a lot of handheld footage, and I use dynamic link to stabilize and fix some shots in AE as a standard part of the workflow.
My system crashed and I had to reinstall everything, and for some reason AE doesn't like the Sony footage any more. Dynamic Linking footage gives me a placeholder item in AE, and importing straight to AE brings up an "unsupported media" error.
I've come across many forum discussions where the only fix is said to be converting the footage prior to importing to AE, but I have been editing Sony EX1 footage in AE for just over a year.
My guess is that some codec I used to have is missing, the Adobe site mentions the ability to add codecs to increase AE's format compatibility, but doesn't go into much detail about how this is done. Anyone have some insight into this situation?
