Apologies if this problems been noted elsewhere but not that I could find.
I’ve been saving a perfectly good file and reopening only to find half my tracks no longer have video and show only the clip’s audio tracks. I’ve had a similar problem when files crashed and recovery versions lost the video, but now it’s just happening when I’m saving normally!
There’s no filters in the master, I haven’t moved any of the original clip files and the tracks themselves don’t even seem to be video anymore.
Is there anyway to restore the video or am I screwed?
I do not know what caused the problem. Perhaps some sort of in-memory data corruption that got saved into the file. You will need to edit the .mlt XML file in a text editor to repair it. Locate every <playlist ...> line with a <property name="shotcut:audio">1</property> directly below it (except for the one with <property name="shotcut:name">A1</property> - that is your audio track, of course). Change the others from “shotcut:audio” to “shotcut:video”. Save and re-open.
I am having the same problem when I simply “Save as” the project: the video disappears leaving only the audio. I printed out the file in WORD, but it doesn’t match up with the suggestions given here, so I don’t understand how to edit the file. A lot of work down the drain, so any advice would be appreciated. I am using a new WIN10 machine and the most recent version of Shotcut as of 12/20/19. Thanks.
