Correction, 2026-10-01: we said Kling O1 and O3 take no end frame and listed Wan 3.0 Prime as taking one on 8frame. On the 8frame canvas, Kling O1 Image and Kling O3 do take a start and an end frame, while the Wan node has a single image slot, so Wan 3.0 Prime cannot get an end frame from 8frame (its model accepts one, the canvas does not send it). The table, the Kling and Wan rules and the FAQ are updated.
Giving a model both the first and the last frame turns image-to-video into a transition you control: the model only has to invent the motion in between. On the 8frame canvas, an end frame works on Veo 3.1 (all three tiers), four Kling models (2.5 Turbo Pro, 2.1 Pro, O1 Image and O3) and Seedance (2.5 and 2.0). Kling v3, 2.6 Pro, 2.1 Master and O1 Reference do not take one, and neither do Wan, Hailuo H3, Happy Horse, Grok Imagine, Gemini Omni Flash or Pruna p-video. The cheapest end-frame clip is Veo 3.1 Lite at 33 credits for 8 seconds without sound.

| Seedance 2.5 | Yes, with a start image and no reference images | 4 to 30 s | 70 (480p) / 157 (720p) for 5 s |
| Kling v3, 2.6 Pro, 2.1 Master, O1 Reference | No | ||
| Wan 3.0 Prime, Pruna p-video | No on the canvas (the node has one image slot) | ||
| Hailuo H3, Happy Horse, Grok Imagine, Gemini Omni Flash | No |
The rules for each
Veo 3.1 switches to a first-and-last-frame mode when you connect both images, and that mode is always 8 seconds long, on every tier. Lite renders at 720p, Veo 3.1 and Fast at 1080p. The provider also crops images that are not 16:9 or 9:16, so prepare both frames in the output shape; details in Veo 3.1 start image requirements.
Kling takes an end frame on 2.5 Turbo Pro, 2.1 Pro, O1 Image and O3, always together with a start image; Kling v3, 2.6 Pro, 2.1 Master and O1 Reference do not take one. 2.5 Turbo Pro is the cheapest of the four at 48 credits for 5 seconds. O3 is the one with free length choice, 3 to 15 seconds, and optional sound (off by default): 57 credits for 5 silent seconds, 76 with audio.
Seedance needs the first frame set before it will take a last frame, and the end frame works only when no reference images are attached. It is either references or first-and-last, not both.
Wan 3.0 Prime accepts an end image at the model level, but the Wan node on the 8frame canvas has a single image slot and does not send one, so no Wan model takes an end frame on 8frame today. Pruna p-video is in the same position.
What first and last frames are good for
- Before and after: an empty room to a furnished one, a sketch to a finished product.
- Hiding a cut: end one shot on the frame the next one starts from.
- Logo and product reveals: land exactly on the approved composition instead of hoping the model stops there. For logos, keep the real mark as an overlay rather than generating it; see AI logo animation.
- Loops: use the same image as first and last frame.
The two frames should share lighting, lens and scale. The further apart they are, the more the model has to invent, and the more likely the middle is to morph.
Cheapest route to a good transition
Test the pair on Veo 3.1 Lite silent (33 credits) or Kling 2.5 Turbo Pro (48 for 5 seconds). If the motion between the frames is right, rerun the same pair on the model you will deliver on. Twenty test transitions on Lite silent cost 660 credits; do the same on full Veo 3.1 with audio and it is 8,960.
