What previz has to answer
Previsualization exists to answer questions before they get expensive: does the scene cut together, how long does it run, where does the camera sit, and does the dialogue fit the shots. An animatic, timed still frames with scratch audio, answers all four. Previzly produces the frames, the timing and the audio from one project, so the afternoon below is realistic for a short scene or a trailer.
Hour one: idea, format, cast
Write the idea as you would pitch it, choose the format the final piece will be delivered in and build the cast. For previz you do not need perfect reference images; two clear photos per character are enough for a canonical avatar with a locked identity. If a character speaks, upload a short voice sample so the animatic can carry scratch dialogue in a voice that matches.
Hour two: breakdown and the edit on paper
Generate the breakdown and read it as a director, not as a user. Reorder shots, cut what the scene does not need, and tighten each shot’s typed fields: angle, movement, lighting and duration. Rewrite beats with short instructions. This pass costs nothing and it is where most of the value of previz is created, because you are editing the film before it exists.
Hour three: keyframes and set plates
Give each scene a set plate so the location holds across its shots, then render keyframes shot by shot. Use takes where the framing matters and move on where it does not. Shots that still wait on a character avatar are flagged, so you always know why something has not rendered.
Hour four: timing, voices and the animatic
Generate the voice lines for the dialogue beats. The app times dialogue shots from their words, at two and a half words per second with a short lead-in and tail, so a shot that carries a line is long enough to hear it. Open the timeline: shots are laid out by duration with their audio, the playhead scrubs through the film, and the animatic plays from any point. Adjust durations in the inspector until the cut feels right.
Showing it
Assemble the project to get a single playable movie file with the frames, the voices and a music bed, and download it. If you later turn some shots into video, the same timeline and the same assembly step produce the next version; the animatic is simply the first cut of the same project. Costs per action are on the pricing page; a previz pass that stops at keyframes and voices stays well inside the starting credits.
