Previous value: -"Text description of the desired animation (e.g., \"walking\", \"jumping\", \"idle breathing\", \"attack slash\")."New value: +"Text description of the desired animation, e.g. \"walking\", \"idle breathing\", \"attack slash\", \"casting a fireball with both hands\". Describe exactly and unambiguously what the character should do. Specific or complex actions are fine; there is no need to simplify them. Do not over-describe, though: too much detail can harm the animation, and an action the model already knows should be named, not decomposed into its steps (\"walking\", never \"move the left foot forward, then the right foot\"). Do not restate what initial_image already shows (the character, its appearance and equipment, the art style, the background, the lighting, the camera), and leave frame count and timing to the frames and duration fields. Negative phrasing (\"no background\", \"do not move the camera\", \"without a weapon\") works only on hydra. On forge, forge-pixel and the legacy models it backfires: naming something you do not want makes it more likely to appear, so \"without a weapon\" tends to produce a weapon. On those models never phrase anything negatively; state only what should happen, and control everything else through the image and the other fields."
