If you're happy with the video then there's no point in forcing yourself to edit it for many more hours, is there?
It probably doesn't add much to your video at that point.
i agree. Edit it until you're happy. If you're happy, your subs will be happy. i make one video a week, about six minutes long. i'm happy to have gotten down to five (5) days of work for one video. Those are more than "six hour" days. i would say 8 hours. Not all of that is editing. i research a topic, write the script, edit the script, shoot the video, edit video for pacing, edit again for volume levels, gather film & still media to be displayed in the video, edit the film clips, edit the photos for size and defect elimination, edit the media into the video, gather original music, edit the music, edit the music into the video, upload the video, upload the subtitles, create the thumbnail, research the keywords & add them, and that's basically it.
