Post-production is the stage where captured material becomes a finished piece: assembly, effects, transitions, sound and delivery. On the platform that work happens in Motion, and its governing rule is that the monitor and the exported file must agree.
01One evaluation, two renderers
Motion's program monitor and its export renderer are different pieces of machinery — one paints CSS, the other paints a canvas. Effects and transitions are therefore evaluated once, into plain numbers, and each renderer derives its own syntax from those same numbers. A transition cannot look one way in the monitor and another in the file, and a blur cannot land at a different radius because the export frame is a different width; blur is carried as a fraction of frame width, so it scales proportionally in both.
Six transitions ship: cross-dissolve, wipe, dip to black, cross zoom, zoom blur, and a signature burn dissolve. Drop one on a clip and drag its badge to set the length. Drops land on the nearest cut; a transition at the head of a sequence or after a gap fades in from black; and a clip without enough tail material behind the cut tucks the incoming clip by the shortfall in a single undo step.
The clip effect set covers brightness, contrast, saturation, hue, blur, grayscale and sepia, applied by dragging an effect onto a clip and adjusted, bypassed or removed in the clip effects tab. Layer properties — position, scale, rotation and opacity — are separate controls on the program.
02Measuring instead of guessing
Motion's scopes read the real program output rather than a sample of it: a luma waveform, an RGB histogram, and audio peaks that include every audible voice on the timeline. Per-clip gain attenuates rather than boosts, because the monitor cannot play above unity and a boost that only appeared in the exported file would be a lie about what you heard.
03Delivery
Export renders the sequence in real time through an offline rig fed from the same media the timeline uses, mixes the audio through its own graph, and records the result to WebM. The finished file uploads to storage and registers as an asset in your Library. If the upload fails the rendered file is retained and can be retried without re-rendering. If a clip's media is missing, the export refuses and names the clips rather than quietly rendering black frames. MP4 output is deferred to a server-side encoder and the panel says so instead of pretending.
04Post as a service
DigiFX also delivers post-production as a service, either inside a full-lifecycle production engagement or on its own. That suite covers colour grading, visual effects, sound design and custom soundtrack composition.
