The number of prompt lines you set will be the number of scenes (number of loop processing times).[IMPORTANT]There are rules for writing prompts. Please use the following format:<pre><code>　　duration (seconds) | character action | camera work</code></pre>　　(separate each item with a “|” symbol)The number of frames per loop (Length) can be expressed by the following formula and the number is variable for each loop.<pre><code>　　(Duration [seconds] × FPS) ÷ (Frame interpolation count + 1) + 1</code></pre>If the number of loop iterations is high, issues with color changes in the reference image may occur. In such cases, adjust the value of “🔧 Image Desaturate.”
