Getting Started

Quick Start

Before you can start using the BpmSlicer script you need to set the checkbox of the following setting to true.

After Effects -> Preferences -> General -> Allow Scripts To Write Files And Access Network (Skripte können Dateien schreiben und haben Netwerkzugang)

Create a composition with some video footage in it and make sure it is selected. Leave all settings in the BpmSlicer as is and click the Slice button at the bottom of the script. The selected footage layer is getting sliced as seen in the image below:
The reason why there are exactly 5 slices is because by default the sliceArray is set like this:
That means you have to create a new sliceArray before you can slice the footage according to your needs.
  1. Select a layer
  2. Set the slicing rate (32 bars, 16 bars, 8, 4, 1, 1/4, 1/8, 1/16, 1/32)
  3. Check the Marker checkbox in case you need composition markers for all slices
  4. Click Slice

Creating a sliceArray

Set Bars

By setting a new value in the Bars dropdown a new sliceArray is created which contains slices that are quantized to the selected bars value and the bpm.

Read Composition/Layer Markers

In the markers tab, choose whether you want to read composition markers or layer markers (selected layer). By clicking the ‚Read‘ button in the Markers tab, a sliceArray is created by all markers of the composition or layer. This only works if there are at least 2 markers existing.

Read Slices from Txt File

By clicking the midi button a file chooser dialog is opened and you get to choose a txt file with informations about all slices. Each line of the txt file contains 4 parameter values (noteLayer, sliceIn, sliceOut, Velocity) that represent one slice. Please refer to Midiconverter (external) on how to convert a midifile into such a txt file.
