Editing Pro Tools (section)

==== Track rendering ====
Audio, auxiliary, and Instrument tracks (or MIDI tracks routed to a [[Software synthesizer|virtual instrument]] plug-in) can be committed to new tracks containing their rendered output. Virtual instruments can be committed to audio to prepare an arrangement project for mixing; track commit is also used to free up system resources during mixing or when the session is shared with systems not having some plug-ins installed. Multiple tracks can be rendered at a time; it is also possible to render a specific timeline selection and define which range of inserts to render.{{Sfn|Avid|2019|p=995–999|loc=45.

Similarly, tracks can be frozen with their output rendered at the end of the plug-in chain or at a specific insert of their chain. Editing is suspended on frozen tracks, but they can subsequently be unfrozen if further adjustments are needed. For example, virtual instruments can be frozen to free up system memory and improve performance while keeping the possibility to unfreeze them to make arrangement changes.{{Sfn|Avid|2019|p=1000–1002|loc=45.
