Almost any format,straight onto the timeline

Shotcut, on a Void Linux desktop of your own.FFmpeg underneath, so the file you were sent opens without converting it.

The application

FFmpeg,with a timeline on it

If FFmpeg reads it, Shotcut edits it — no import step first.

The formats you have

Hundreds of containers and codecs, including 4K and 10-bit, read natively.

Filters with keyframes

Colour, audio and transform filters, animated over the clip rather than fixed.

Export presets

Render to a preset or your own FFmpeg arguments, written to the volume.

How you run it

Every defaultis one override away

The session reads its settings from the environment, so you set them on the start line.

VNC_PASSWORDWhat the tab asks for. It ships as dxflow, and everyone reading this knows that.

PANEL and TASKBARBoth hidden, so the timeline has the whole screen. Show either one to get the desktop back.

AUDIO_RATE and AUDIO_CHANNELSSound is on here, since this is an editor. Raise the rate to 44100 for a mix you actually have to judge.

start it your way

$ dxflow workflow start shotcut --override env.app.VNC_PASSWORD=something-long

$ dxflow workflow start shotcut --override env.app.AUDIO_RATE=44100 --override env.app.AUDIO_CHANNELS=2 --link

Good to know

MLT underneath,FFmpeg behind that

The format list is FFmpeg's, which is most of why Shotcut opens whatever a camera or a colleague hands you.

It opens almost anything

Containers and codecs come from FFmpeg rather than a plugin list. There is rarely a conversion step before you can start.

Encoding is CPU work

Export time tracks core count. Pick the machine for that, and let it run while you do something else.

Projects belong on the volume

Footage, the project file and the export all under /volume, or the next start opens an empty timeline.

The image

Pulled once,then it stays

Shotcut arrives as one image. This is what comes down the first time, and what the disk should have free for it.

What it asks for

What it wants,and what it needs

The definition asks for 4 cores and 8 GB. The image comes up on less than that, and a start given --fit trims the ask to whatever the machine actually has.

4 cores · 8 GBAsks forwhat the definition writes down

2 cores · 4 GBRuns onthe least the image comes up on

Not neededGPUit works on the cores alone

The ask is not the floorThe definition writes down what suits the work. The image itself starts on less, which is what the second figure is.

--fit caps it to the hostA start given --fit trims each step to what the machine actually has, for that start alone. The definition is never rewritten.
