LTX First / Last Frame Workflow
Image-to-video where both endpoints are locked stills. Use when the start pose and the end pose are known (turn, walk-to-mark, product rotate, match-cut). Stronger continuity than open-ended I2V.
Cinesmith ships this as 05_ltx2.3_first_last_frame_to_video.json (or LTX 2.5 equivalent). Run it on the video Comfy instance (often a 3090), not the stills box.
When to Use
- User has (or can generate) a start frame and an end frame
- Need a camera or body move that must land on a composed last look
- Multi-beat stories where shot N's last frame is shot N+1's first
Don't use for: riffing motion from one still (use workflow_ltx_i2v); text-to-video with no anchors.
