Reaper-Scripts/4PointCutting

Four Point Cutting

This set of scripts is an attempt to bring the famous four point editing features known from Magix' Sequoia to reaper. Basically it enables you to put together audio material from several takes in a fast and precise way by defining "source" and "destination" sections with markers and then let the edit happen automatically. Several scripts are provided, most do set up what the edit shall look like while one main script does the actual work.

Features

• Select source and destination regions by placing "special" markers
• Optionally select source and destination tracks (in same project only)
• Crossfade items after copy-pasting them
• Automatically advance destination area after each edit
• Several edit modes, three out of four markers are needed

Requirements

This script does not work properly without SWS extensions (get them for free from http://standingwaterstudios.com/).

Usage

Tipp

I do highly recommend to setup the most important functions (scripts) as easy to reach keyboard shortcuts. Like that a very fast and easy workflow can be achieved. For example one could map the scripts to keys like that:

• 4Pcut_set_src-in to 1 key
• 4Pcut_set_src-out to 2 key
• 4Pcut_set_dst-in to 3 key
• 4Pcut_set_dst-out to 4 key
• 4Pcut_execute to 5 key

Basic functionality

• Set the beginning of the "source" region, from which the audio material will be copied by executing 4Pcut_set_SRC-IN (e.g. press 1)
• Set the end of the "source" region, from which the audio material will be copied by executing 4Pcut_set_SRC-OUT (press 2)
• Set the beginning of the "destination" region, to that the audio material will be copied by executing 4Pcut_set_DST-IN (press 3)
• Do the actual edit by executing 4Pcut_execute (press 5)
• Find the next source region you want to add and place source-in and source-out markers accordingly and run the execute script again. The destination marker(s) will be set automatically.

Edit modes

The script can be run with every combination of 3 markers. The two of them that specify a complete "region" (src-in and src-out or dst-in and dst-out) are used to determine the length of material to copy. The third marker only needs to specify one point of the other region, the length will be the same as the other region.

• src-in, src-out, dst-in set: Audio from the region between src-in and src-out will be copied after dst-in. dst-in will be moved to the right about the length of the copied material.
• src-in, src-out, dst-out set: Audio from the region between src-in and src-out will be copied before dst-out. dst-out will be set to the right about the length of the copied material
• src-in, dst-in, dst-in set: Audio from the src-in point with the length of the region between dst-in and dst-out will be copied after dst-in. dst-in and dst-out will be moved to the right about the length of the copied material.
• src-out, dst-in, dst-out set: Audio from the left of the src-out point with the length of the region between dst-in and dst-out will be copied after dst-in. dst-in and dst-out will be moved to the right about the length of the copied material.

If all 4 markers are set, the shorter region of the 2 specifies the length to be copied. The dst-in and dst-out markers will be moved to the right about the length of the copied material.

Scripts

• 4Pcut_set_src-in, 4Pcut_set_src-out, 4Pcut_set_dst-in and 4Pcut_set_dst_out set markers with special names that are used to specify the source and destination regions to be edited.
• 4Pcut_reset_markers deletes all four of the special markers, if present.
• 4Pcut_execute executes one edit, copies the audio material from source to destination and sets the destination markers accordingly for the next edit step.
• 4Pcut_set_src-tracks sets the currently selected tracks as the source tracks from which audio material will be copied. If unset, all tracks will be used.
• 4Pcut_set_dst-track sets the first of the currently selected tracks as the first destination track to which audio material will be copied. If unset, track one will be used.
• 4Pcut_select_src-tracks selects the stored source tracks set by 4Pcut_set_src-tracks.
• 4Pcut_select_dst-track selects the stored destination track set by 4Pcut_set_dst-track.
• 4Pcut_reset_src-dst-tracks resets the source tracks to "all" and the destination track to track one.
