How to Prep an Audio Session from a Video Project • Prepare a dummy-proof list to give to the video editor or producer outlining exactly what you need to do you job. This is called a list of deliverables. • Ask for an OMFI file generated from the Avid or Final Cut Pro systems. • OMFI format was created by Avid and Digidesign to make useful and efficient transfers between video and audio editing systems. • Digital audio files should be 16-bit/48kHz AIFF because this is currently the standard video format. • Make sure that all video editing is complete and there are no changes to be made.
Syncing to External Video Decks • Pro Tools HD systems employ SMPTE time code in order to sync to video and film. SMPTE is much more accurate than MIDI time code. • Time code can be written to a blank track on an audio tape deck or into an hidden area of a video frame. • Digidesign makes a hardware unit called the Sync I/O, which allows communication between your Pro Tools system and external video decks. • When Pro Tools is slaving, session playback is controlled and consequently moves in sync with an external machine.
How to Calibrate Monitoring • When you are mixing a video or film session, your mix will need to translate properly at playback venues other than your studio. • Pro Tools output level can be relative to whatever system it is calibrated to. • You can use Pro Tools’s internal Signal Generator to make sure that you are listening at the proper volume so your mixes arrive at the appropriate levels. • Buy an SPL loudness meter and use it to determine levels where you are listening.
Working with Stems • In postproduction, the three different elements of a sound track are broken down in to smaller groups called stems. • The three typical stems are dialog, effects and music. • Make a custom I/O setup for stem mixes • Use Pro Tools internal busses to set up aux submixes for each stem. • When your mix is complete print all of the stems separately as a stereo mix. • Separate stems allow for international versions, music adjustments or remixing with individual elements.
Postproduction Editing Tricks • Control+Click / Start+Click any region with the Grabber tool and its start point will jump directly to where your edit cursor is. • Control+Shift / Start+Shift any region with the Grabber tool and it will move the regions start point to the edit cursor. • Command+Control / Ctrl+Start any region with the Grabber tool and its end point will align with your edit cursor. • Use blank regions to spot Foley.
Surround I/O Setups and Formats • Surround mixing starts in your I/O setup. • There are three types of surround output formats you can use to determine which output of Pro Tools is going to which channel of the surround speakers. • After you setup your I/O any audio track can be output in surround. • For film and video postproduction, the multichannel setup is most often used to establish a spatial effect. • Surround is HD only but you can trick an 002 into doing it.
