trailer-shot

Pick a shot archetype such as hero close-up or establishing wide, optionally generate a reference image to lock subject identity, then call summer_generate_video with a model like kling and a 5-second duration. Poll summer_check_job until the job completes to get the video URL.

Use ltx ($0.10) for cheap blocking and B-roll, kling ($0.50) as the default for final hero shots, minimax for anime styles, and veo3 ($1.00) only for the one pitch-perfect shot. Note kling-turbo and veo3 work text-to-video only and reject reference images.

The aspectRatio parameter only applies on the text-to-video path. Once you pass an imageUrl reference, the clip inherits the reference image's framing, so vertical 9:16 output requires a genuinely portrait reference image built in the Summer dashboard.

No, Summer Engine has no MP4 or WebM loader and only accepts .ogv (Ogg Theora). Transcode with ffmpeg using libtheora before importing via summer_import_from_url; for editing in DaVinci or Premiere the original MP4 works directly.

The call is asynchronous and returns a jobId with queued status rather than a URL. You must poll summer_check_job with that jobId until it reports completed before the video link is available.

Avoid it for multi-shot narrative sequences with dialogue (use cinematic-cutscene), seamless background loops (use animated-loop), and static key art. Also avoid chaining multiple actions in one prompt, since each generation should be a single composed beat.
