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?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)
I don’t really know what’s causing the issue, but basically, whenever I export a video and upload it to youtube, the audio gets delayed and at the end of the video, the last frame freezes until thee audio is finished playing. Let me know if edit friendly is the problem considering I decided to ignore that.
