Studio - Post

I was not supposed to do post production, but it so happened that because the editing was a rush job, it wasn't done right. The editor had to leave so I had no choice but to do the editing myself. I did learn alot.
First, the audio must be normalized or level. Your best bet is to keep them averaging -12 db and peaking at -6db max.
Sometimes the audio is recorded too low. There are many ways to fix that. First and most known way is to duplicate the audio tracks. The problem with that is you get a ridiculous amount of audio tracks, making edits hell. On FCP, another way is turn on audio overlays and drag the level line up or press ( control + ] ). The problem with that is if you made any pen tool edits, doing this will mess them up, and the max gain you get is 12 db. A much better way is to go to Effects>Audio Filters>FCP filters> Gain. Gain allows you to boost the audio up to 96db. Now becareful cause that brings out the static and room tone, and any other noises in the room.
Sometimes a piece of audio might be too loud, you can do the gain filter, pen tool, or you can highlight it an press (control + [ ).
Other things, snapping is (n). Linking is I believe ( option + L). Stereo pairs can be created or removed by going to Modify> Stero Pair, or pressing (control + L). Mastering is ( control + M). To create a duplicate clip, click and hold the clip then press (option). To select one specific track (option click it). If a piece of audio and video get out of sync, (the red numbers show up on the clip) take off linking, and select the audio or video and line them up. The one way slip tool will allow you to make a clip smaller while dragging everything behind it along. For need specific rendering, make an in or out point around it, or just highlight the clip and press (cmd + R).

When mastering or capturing a tape, check the settings on the deck itself with the menu button. Also for mastering, select automatically start recording.
