You can also watch the before-edited video side by side with the one you are QC-ing by clicking on History. From here, you will have the option to Linked Playback which means that the videos are played at the same time so you can check the difference side by side.

Whenever you click on the instruction section, the video will be stopped accordingly. You won’t have to fast-forward or rewind to find the exact moment you want to note down. After writing the notes, hit Ctrl/ Cmd + Enter to save your notes.

And, by clicking on a comment, the player will also jump to the frame in the video that the comment was made on.
