I have been editing a project in Audition that has video, and at a certain point in the project the video is left on a black screen. It only gives an image when it paused the playback and it is only with a project, do you know why?
You haven't said whether this is on a Mac or a PC, but if it's a PC then it's definitely worth checking to see if you have an updated video driver available - this has been a frequent occurrence with Windows and their updates, and can make a lot of difference to the way it performs.
Well, it is a PC, the thing is that it is only with a specific project and with the same video, since when opening another project with the same video always at 12:30 the video goes black, you cannot see anything.
Then the chances are that there's a glitch in the video - possibly to do with key frames.
