VIDEO

Choose Flash for a draft or Standard for the delivery size

Compare the output requirements first: duration, resolution and framing.

Draft the camera path

For a short clip, try Flash at 720p. If the deliverable needs 1080p or more than 20 seconds, choose Standard.

Try a first-frame brief

“Begin with the uploaded image. Move slowly from left to right past the vase. Keep the vase on the same mark and the light direction unchanged.”

Check continuity through the shot

Look at the first few frames and the final position of the subject. If you upload an image, crop it before upload to set the framing.
