What is your operating system?
What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
Can you repeat the problem? If so, what are the steps?
I have a quicktime video (.MOV) which runs just fine in the VLC player. But after editing it with Shortcut and exporting it as MP4, video and sound are drifting apart, up to 5 seconds. The video is lagging behind the sound. However, I have the same problem with “Sony Vegas”, ist this a “Quicktime” problem? Anything I can do in the settings? Would it be helpful to convert it to MP4 first?
Thanks for any advice!
