As stated above shotcut will play the video just fine until I drag it down to the timeline to work on it. At which point it stops and restarts the playback but doesn’t actually play anything. Any help would be massively appreciated as I have a video that needs to get out tomorrow.
You haven’t provided any information except for what you’re experiencing.
I’ve been using Shotcut all day and I have not experienced this once, and I’m a timeline editor.
I wrote a tutorial on requesting support a while back: Requesting Support
The more information there is, the quicker someone may be able to help you find a solution.
It is not possible to drag a project to the timeline. Also, provide operating system, shotcut version, and more steps.
