Audio layer

What can I do with the audio layer?

With the audio layer you can play audio files.


How do I create an audio layer?

Choose LAYER > Add layer > Add audio layer... to create a new audio layer.

The new audio layer can be selected from the layers dropdown to make it the active layer.

Start position

Audio files start playing at the beginning of the show and are mixed with all other layers containing audio.

Codecs

If BluffTitler fails to play your audio file, you are probably missing an audio codec. Learn more about codecs.

Audio layer properties

Volume

The volume.

VJ dialog

Choose LAYER > VJ... to display the VJ dialog.

With the VJ dialog you can connect layer properties to the audio volume. This way you can make your show dance to the beat. In sync, fully automatically and in combination with any effect.



Property

This lists all properties of the active layer. Use the dropdown to select the property you want to connect to the audio volume.

Up to 3 properties can be connected per layer. Use the scrollbar to the right to add another property.

Frequency range

The layer property can be connected to a limited audio frequency range. From very low (20 Hz) to very high (8000 Hz).

For example, to make your layer listen to the bass drum, select the low frequencies.

The default range of (20 Hz, 8000 Hz) makes your layer listen to all frequencies.

Sensitivity

The 3 sensitivity textboxes correspond to the 3 sliders of the selected property. The values are added to the property when the audio is maximum.

For example, when the Text position property is selected, a value of (0,100,0) means that at most 100 is added to the vertical position. Use a lower value to make the text jump less high.

When a colour property is selected, a value of (255,0,0) means that the audio can turn blue (0,0,255) into purple (255,0,255).

The default value of (0,0,0) does nothing.

Threshold

Audio with a volume below this value is ignored. This value must be between 0 (silence) and 1 (maximum volume).

For example, a value of 0.5 means that the layer only begins to respond to the music when the volume is medium high.

Max

Audio with a volume higher than this value is treated as maximum volume. This value must be between the threshold value and 1 (maximum volume).

VJ effects

Next to using the VJ dialog, you can also make your layers dance to the beat with the VJ effects.

Synchronization issues in realtime/editing mode

BluffTitler uses DirectShow to play video and audio files. This means that you require a DirectShow decoder filter for the format you want to play. Unfortunately not all filters behave as they should.

A popular MP3 decoder filter adds a delay of almost a second to songs encoded with a bitrate of 320 kbps. Luckily the exported video file plays fine, but if realtime performance is important this bug can be worked around by re-encoding to a bitrate of 256 kbps or by converting it to a WAV or WMA file.

Synchronization issues in exported videos

A video with audio contains 2 streams: a video and an audio stream. Sync problems can occur when your video is too big for your system to load both streams in time. This can be fixed by using compression.
