Message: do you want to change editor sequence settings to match the clip?
I have imported my first video and trimmed as per the YouTube tutorial. On dragging to the timeline this message appeared
Do you want to change editor sequence settings to match the clip?
What is happening here please?
The MP4 file is from my Samsung S6 mobile.
I know nothing about video parameters. I just want to trim some athletics videos to give the key moments, and then to slow-mo them for athlete instruction.
