- 01:25 ↗
Extend video clips forward or backward in Seedance 2.5 by uploading the target clip and matching subject pose, lighting, and camera angle in the extension prompt.
- 03:52 ↗
Backward shot extension enables creators to generate preceding context for a scene by describing actions that occurred immediately prior to the clip's start frame.
- 05:27 ↗
Connect two separate video clips seamlessly by feeding both into Seedance 2.5 as references and specifying a intermediate trigger action.
- 07:27 ↗
Formulate transition prompts by defining the initial action in video one, detailing environment and camera transformations, and concluding on the exact opening frame of video two.
Workflow outlined in the video
- Select Seedance 2.5 in OpenArt and enable the Extend Video feature to elongate clips forward or backward.
- Draft forward extension prompts that mandate matching subject pose, camera placement, lighting, and motion direction from the original video's final frame.
- Stitch separate scenes together by uploading Video 1 as the before clip, Video 2 as the after clip, and prompting an explicit action trigger for the transition.
- Calibrate the transition generation duration to match the time required for physical and camera transformations between stitched clips.
