I'm using a mixture of 1920 * 1080 120 fps and 4K 29.97 fps video clips from a go pro and trying to render to 4K 29.97 fps.
Does anyone know what effect the project properties should have? e.g. I thought only the export settings would be relevant however I tried changing the project properties to 3840 * 2160 * 29.97 fps after finishing editing.
The entire work area is only approximately 4 minute long however after changing the properties to these values I then noticed the time line extended the clips to approximately 15 minutes long. Oddly enough there are also gaps and black video when the properties were changed.
Should I have set the project properties at the start? Are the settings helpful for the workflow and export? I really don't want to reedit the video if I can help it after spend a few hours trimming
