If you have a video file with several audio tracks, for example different languages, you can easily upload it to Video.Taxi. These different audio tracks can then be changed seamlessly in the player during playback.
To do this, upload it as normal in the MEDIA section. If you select the video and scroll down, you will see under "Audio tracks" which audio tracks the video has. Under "Actions" you can select which of the tracks should be played in the player by default. You can also use "Customize metadata" to change the name of the track that is displayed in the player. This can be useful, for example, if you have three different audio tracks with the same language but different dialects. You can also create a voice-over audio track as a translation; you can find out how this works here.
In the player, the respective audio track can then be selected via the headphone symbol at the bottom right, the change is seamless.
