2 years ago I edited a project with HDCAM-files converted to cineform AVI-files in Premiere CS4. In the meantime I have updated to the newest Cineformdecoder. Now I have to make some changes in this old project, but when I open my project im CS4, my cineformfiles won`t play. If I try them in windows media player everthing is working fine. The only chance to get the files played within CS4 is to reconvert them to MOV-files - then everthing is working. But this is a big project with nearly 200 files and I haven`t the time to reconvert all of them.
So what`s the problem with my old cineform AVI-files?

it would probably help if you were more specific. What version of Cineform are you currently using? Neoscene? Neo HD/4K? Prospect HD/4K? Version #.#.?

It might be a CS4 importer issue not your source AVIs. Please sent a short AVI to support.

In my old project I`ve used Prospect HD version 3.x. Now I`ve ugraded to NeoHD version 5.05. In CS4 I get only a black thumbnail for the AVI-files.
