I separated the video and audio of a video and deleted the video thinking i could do control z. Then I added a new video to the audio and all the sudden camtasia crashed and now I don't have the video portion from the audio. Is there any way I can like back up in time with camatasia?
Restarting Camtasia after a crash can sometimes allow you to save the project. You will get a pop up that asks you if you want to recover the previous project "Something like that" . Then, Camtasia will attempt to recreate the project. It may not be exactly as it was when it crashed. Camtasia auto saves projects every 2 minutes by default.
If Not, Camtasia is a Non-Destructive editor. This means that your original video files will still be unchanged so you could always start your project over from scratch if need be.
