If you can’t get an EDL there is a brilliant little program for PC users called Handysaw Video Scene Detection Software HandySaw DS | HandySaw DS | Products | Davis Software
that can create a CMX3600 EDL from a video file. You can import that edl into Nuendo so that every cut will be defined by cycle markers if you setup the import as such, then just double click each cycle marker and you can have your shot clearly defined with the left and right locator. Can massively speed up the editing process. It’s not free but it’s been a great investment for me.
It doesn’t work with all video files but I just convert my working video file to a small file for it to scan and create the edl. It’s worth the conversion time.
If Nuendo itself could create cycle markers from video files, there would be a lot of seriously happy sound editors.
