then drag and drop video from the media file project library to the timeline.drag and drop video file in the editing app's project's "media library" section (not the timeline).Open the editing software and close the "new project" window that opens, if any.(record the source material in the format you want, codec can be anything.we can stop here step one was already wrong (IMO).go to "file" -> "new project" specifing color, resolution and so on.

Wrong approach to making a video editing project start to finish : This applies to any video editing software. Well if you never specify anything it never alters anything.
