Transitions

--transition KIND:DURATION[:MIN-CUT]

puts a transition at each cut auto-editor makes, and at the start and end of the timeline. The video and audio transitions are linked: they cover the same span.

bash

auto-editor video.mp4 --transition dissolve:1sec        # cross-dissolves, fades at the ends
auto-editor video.mp4 --transition push:0.5sec          # a Premiere Pro transition
auto-editor video.mp4 --transition clock-wipe:1sec:0    # at every cut, however short
auto-editor video.mp4 --transition constant-power:1sec  # audio crossfade kind; video dissolves

```
DURATION
```
: how long each transition lasts (
```
0.5sec
```
, or a bare frame count).
```
MIN-CUT
```
(default
```
1sec
```
): skip cuts whose removed source is shorter than this, so trimming a short pause stays a hard cut instead of a stutter.
```
0
```
transitions at every cut.

A transition draws on the footage that was cut out (its handles), so:

it may be shortened, or skipped, when a clip or the removed stretch is too short to support it;
whatever was in the removed stretch shows mid-transition. If that's filler you don't want seen, keep transitions short or raise
```
MIN-CUT
```
.

Kinds

Every transition Premiere Pro has, under its Premiere name in lowercase with dashes. Those in its Legacy folder that share a name with a newer one end in

-legacy

. They play at Premiere's default settings.

dip-to-color

dips to the timeline's background color (

-bg

Audio. A video kind gives the audio a plain crossfade. Audio has three kinds of its own:

dissolve

(Premiere's Constant Gain;

constant-gain

is accepted too),

constant-power

and

exponential-fade

. Naming one of those keeps the video a cross-dissolve.

How close to Premiere. auto-editor renders every kind itself. Compared frame by frame with Premiere's own renders,

push

clock-wipe

and

barn-doors

match to within encoding noise and

page-peel

is close; the others haven't been measured. Expect simple dissolves and wipes to be near, and effects like

glitch

light-leak

, which draw their own noise and colors, to differ. For Premiere's exact look, export with

premiere-otio

and let Premiere render them.

Per-transition control: v3 timelines

--transition

uses one kind everywhere. For a different kind or length at each cut, export a v3 timeline, edit its

transitions

key, and render it:

bash

auto-editor video.mp4 --transition dissolve:0.5sec --export v3 -o edit.v3
# edit edit.v3, then:
auto-editor edit.v3 -o out.mp4

"transitions": {
  "v": [[{"kind": "push", "at": 300, "dur": 15, "alignment": "center"}]],
  "a": [[{"kind": "constant-power", "at": 300, "dur": 15, "alignment": "center"}]]
}

at

is the edit point in timeline frames,

dur

the length in frames, and

alignment

start

(a fade in from a clip's start),

center

(across a cut between adjacent clips) or

end

(a fade out at a clip's end). Video tracks take video kinds; audio tracks take

dissolve

constant-power

exponential-fade

. See https://auto-editor.com/docs/v3.

In editor exports

Export	What arrives
`premiere-otio`	Every kind, as Premiere's own transitions. Of the obsolete kinds, Premiere still reads `page-turn` and `page-peel-obsolete` ; the others are sent as a dissolve, since Premiere would drop them and leave a cut.
`premiere` , `resolve-fcp7` (FCP7 XML)	Cross Dissolve; the dips (as Dip to Color Dissolve, which Premiere reads as its Dip to Black or White); `wipe` (as Edge Wipe); Cross Fade (0dB) or (+3dB) for audio. Every other kind becomes a dissolve.
`final-cut-pro` , `resolve` (FCPXML)	Cross Dissolve spine transitions.
`shotcut` , `kdenlive`	Same-track dissolves and crossfades, fade filters at the ends.
`v3`	Every kind, unchanged.

To bring the kinds into Premiere, use

premiere-otio

v1

v2

and

clip-sequence

exports drop transitions; a clip sequence's files are separate, so a transition between them has no meaning.

Importing

FCP7 XML and FCPXML imports read the transitions those formats name: Cross Dissolve, Additive Dissolve, Dip to Color Dissolve (black or white by its color), Edge Wipe, the Irises, Page Curl, Star, Cross Fade (0dB/+3dB), and Premiere's names generally. A name it doesn't know plays as a dissolve.

Recipes

bash

auto-editor talk.mp4 --transition dissolve:0.3sec           # soft cuts in a talking-head video
auto-editor vlog.mp4 --transition whip:0.4sec:2sec          # whips, only where 2s+ was removed
auto-editor podcast.mp3 --transition constant-power:0.2sec  # audio-only: smooth crossfades
auto-editor video.mp4 --transition push:0.5sec --export premiere-otio   # finish in Premiere
