Auto-Editor: Effort free video editing!

Auto-Editor is a command line application for automatically editing video and audio by analyzing a variety of methods, most notability audio loudness.

---

Before doing the real editing, you first cut out the "dead space" which is typically silence. This is known as a "first pass". Cutting these is a boring task, especially if the video is very long.

Installing

pip install auto-editor

See Installing for additional information.

Cutting

Change the pace of the edited video by using --frame-margin.

--frame-margin will including small sections that are next to loud parts. A frame margin of 8 will add up to 8 frames before and 8 frames after the loud part.

auto-editor example.mp4 --frame-margin 8

Set how cuts are made

Use the --edit option. to change how auto-editor makes automated cuts.

For example, edit out motionlessness in a video by setting --edit motion.

# cut out sections where percentage of motion is less than 2.
auto-editor example.mp4 --edit motion --motion-threshold 2%

# --edit is set to "audio" by default
auto-editor example.mp4 --silent-threshold 4%

# audio and motion thresholds are toggled independently
auto-editor example.mp4 --edit audio_or_motion --silent-threshold 3% --motion-threshold 6%

Exporting to Editors

Create an XML file that can be imported to Adobe Premiere Pro using this command:

auto-editor example.mp4 --export-to-premiere

Similar flags exist also for:

• --export-to-final-cut-pro for Final Cut Pro.
• --export-to-shot-cut for ShotCut.

Other programs might also be able to understand these formats, but if they don't. You can use --export-as-clip-sequence which exports to many files that can be imported and used in other editors.

Manual Editing

Use the --cut-out option to always remove a section.

# Cut out the first 10 seconds.
auto-editor example.mp4 --cut-out start,10sec

# Cut out the first 10 frames.
auto-editor example.mp4 --cut-out start,10

# Cut out the last 10 seconds.
auto-editor example.mp4 --cut-out -10sec,end

# Cut out the first 10 seconds and cut out the range from 15 seconds to 20 seconds.
auto-editor example.mp4 --cut-out start,10sec 15sec,20sec

And of course, all the audio cuts still apply.

If you don't want any automatic cuts, use --edit none

# Cut out the first 5 seconds, leave the rest untouched.
auto-editor example.mp4 --edit none --cut-out start,5sec

And the inverse

# Leave in the first 5 seconds, cut everything else out.
auto-editor example.mp4 --edit all --add-in start,5sec
