Get Export File Extension

Category: Pr Rendering

Returns the output file extension implied by an .epr preset for a sequence. Returns the file extension that Premiere reports for a given .epr preset and sequence. sequence is optional; the active sequence is used by default. Use this to build deterministic output paths instead of guessing extensions such as .mp4 or .mxf. If sequence is omitted, the block uses the active sequence when supported. Use presetPath to choose the sequence preset. Without it, Premiere uses its default behavior for new sequences.

Render Sequence With Embedded Preset As ABSCRIPT Build Spec

Portable ABSCRIPT BUILD SPEC example that prompts for an `.epr` preset file, embeds it, derives the output suffix, and renders the active sequence. This is the portable embedded-preset counterpart to the runtime render patterns that use known preset paths.
