This is an edit of Goblintide’s original 6 second video. I hope you are OK with this, your generations are so good (probably the best out there), but I needed to see this one as longer video. I didn’t want to remove the watermark, but also didn’t want to misrepresent it, so I added a small text “edit by” below.

I extracted some frames and expanded the original work to 3 minutes at 32 frames. You can download it and watch at 0.75 speed and it is also good when it plays at 24 frames. I photoshopped some details to fit my own preferences more. It’s not as jiggly and bouncy as the original, but it is much longer and has a bit of variety (0:40 and 1:50). Butt is nice, but it’s the expressions she makes that transfix me. Mares are so wonderful.

Edit: There’s a discontinuity at 2:50. I failed to notice it in time. But since it’s so close to the end (10s) I will let it be.

I also managed to reduce the brightness/contrast/saturation blip that happens at the end of each clip. Not perfect, but less noticeable now.

The original vid was vertical, not square. I used Photoshop to generate the extra margins.

I tried experimenting with prompts but most of them caused the neck-breaking head rotation thing. Only two mostly kept the head rotation within reason.

Prompt
A pony girl having sex in doggy style position with a human male. Male point of view.
She smiles and giggles, looking very pleasured.

She wiggles her butt gently left and right, without penetration, teasing her partner. (this is used for 0:40 and 1:50)
OR
She rhythmically and very slowly thrusts herself deep into him. Her butt cheeks are bouncing. (Everything else)

Negative prompt
twisted neck, unnatural neck bend, 180 degree head turn,looking at you,looking at the camera,facing the camera,looking at the vieweer,
unnatural head rotation, over-rotated head, impossible neck twist, broken neck, disjointed anatomy, head turned 180 degrees,
backwards gaze, owl head, reverse head orientation, unnatural body-head mismatch, head not aligned with body

Used WAMU V2 - Wan 2.2 I2V on Huggingface.co for img2vid first and last frame.
