Hi,
sorry for refreshing this quite old thread but I get the same error message as described above.
AGK Version 2.13b
I get the message "Trim: Cannot trim if there is no video...." everytime I want to encode an avi file (Huffy or XVid for testing). And I am quite sure that there is a video.
When trying to encode DV avis I did not get this message but agk freezes when analyzing the video.
Uninstalling of avi file handler from VDub and debug frameserver did not help
Avisynth 2.55 is installed and was tested successfully
Thanks
