Notes & timestamps
The notes beside a Video, Clip, or Replay are the same notes from your Notes page.
Videos and Clips use the selected character's Primary Notebook. Replays first ask which character the notebook is for, then let you use that character's Primary Notebook or opponent matchup notebook.
A useful replay setup is to choose the character you are learning, open that character's matchup notebook for the opponent, and record what the pro does in that matchup.

Choose the character
A replay first asks which character the notebook is for. The notebook choices that follow belong to that character.

Pick the matchup notebook
Choose the Primary Notebook for general Yasmine notes, or Yasmine vs Manon to record what the pro does with Yasmine in this matchup. Then choose the page you want to write in.

Save a video reference
Choose the clock at the start and end of the moment. The real preview lets you check and adjust the video reference before saving it to the selected Notes page.

Attach a Combo
Choose Combo, enter the notation, and leave Save to Tech Library selected. The saved Tech entry keeps the same video reference.
Open a saved video reference. Choose the video reference from the Notes page to reopen the same part of the Video, Clip, or Replay. A Tech entry saved from it keeps that same reference.
