Supported Audio Format (Enterprise) [VE 21.4 OG]

VidiEditor allows one to set specific shape tags as audio proxy format. All items having this shape defined will be found in the VidiEditor search. Another option is to user original as audio format. In result the VidiEditor will filter on following criteria when orginal is configured to be used.

Shape: Original

Codec Family: AAC

Media Type: Audio (no video component)

File Extension: m4a, mp4, aac

It is still recommended to set a shape tag for audio-only files as it clearly specifies a usable file.

Format Specification

Due to the playback in VidiEditor source and timeline players, the usage of audio-only in VidiEditor is limited to:

Container: MP4, M4A, AAC

Samplerate: 48 kHz, 44.1 kHz

These parameters are also used for recordings done on voice-over recordings. A suitable shape tag will be added during the installation:
