Fra QLabs hjemmeside:
QLab can access all audio channels within the first audio track of your video. This can be confusing, since the words “channel” and “track” are often used interchangeably. In the world of video files, one video can contain multiple tracks, and each track can contain up to sixteen channels. When a video is prepared for DVD production, the first track might represent the 5.1 surround mix, and thus contain six channels. The second track could be an alternate stereo mixdown, and thus contain two channels. Since QLab can only access the first track of a video’s audio content, it’s important to keep these differences in mind when preparing your video files.
Det betyder at vi er nødt til at holde os til et enkelt lydspor med flere kanaler. Guiden her viser hvordan man sætter dette op i Adobe Premiere.
Først skal sekvensen sætte korrekt op i Premiere. Benyt følgende indstillinger under “Tracks” i sekvens-indstillingerne:
Tracks indstillinger
Master | Multichannel |
Number of channels | 8 |
Set all channels to | Mono |
Output assignment
Track Name | Master Track Channel |
---|---|
Audio 1 | 1 - 2 |
Audio 2 | 1 - 2 |
Audio 3 | 3 - 4 |
Audio 4 | 3 - 4 |
Audio 5 | 5 - 6 |
Audio 6 | 5 - 6 |
Audio 7 | 7 - 8 |
Audio 8 | 7 - 8 |
Panning
Track Name | Pan / Balance |
---|---|
Audio 1 | -100 / Left |
Audio 2 | 100 / Right |
Audio 3 | -100 / Left |
Audio 4 | 100 / Right |
Audio 5 | -100 / Left |
Audio 6 | 100 / Right |
Audio 7 | -100 / Left |
Audio 8 | 100 / Right |
Se et eksempel med ovenstående instillinger.
Eksportering
Vælg Quicktime og fx ProRes LT med følgende indstillinger:
Stream | Output Channels | Source Channels |
---|---|---|
1 | 8 Channels | 1 - 8 |
Husk også at ændre “Channel Layout” til Discrete.
Se et eksempel med ovenstående instillinger.
Du kan med fordel se denne Youtube-guide som forklarer ovenstående, men huske at vælge Channel layout: Discrete når du eksporterer – ellers kan QLab ikke genkende mere end ét eller to channels.
