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.
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.
Due to the playback in VidiEditor source and timeline players, the usage of audio-only in VidiEditor is limited to:
Container: MP4, M4A, AAC
Audio Codec: AAC
Samplerate: 48 kHz, 44.1 kHz
Bitrate: 192 kbps
Channels: up to 8x stereo
These parameters are also used for recordings done on voice-over recordings. A suitable shape tag will be added during the installation:
