Timecoded Commenting on Videos
For video files, you can leave comments directly on the timeline by simply playing the video and leaving comments using the comments bar. Comments will automatically be added to the timeline with the corresponding time code.
You can jump to the comments by either clicking the small dot on the timeline, or by clicking the timecode in the comment on the right side comment bar.
If you want to leave a comment with no timecode, just uncheck the timecode box beneath the comment bar.
