If a photo will not load
Check the file first. The upload field accepts JPG, PNG and WebP images up to 10 MB each. A phone photo saved as HEIC will need conversion before it can be selected here. Renaming a file extension does not convert its contents. If a file has the right type but cannot be decoded, export a fresh copy from an image editor and try that copy. An error message should appear beside the studio rather than leaving you guessing.
If the wrong role or price is selected
Check which role each photo belongs to, then select 5, 10, or 15 seconds and 768p, 1K (1080p), or 2K. Each generation uses one video credit. Text mode needs a prompt and a supported ratio; first-frame mode uses one image with adaptive framing. Reference mode accepts public HTTPS media URLs. Do not mix a first-frame image with the reference-input mode.
If you are expecting a finished video
Keep your task ID if submission times out. The site checks the provider every 8 seconds for up to 15 minutes, then lets you resume later. An uncertain submission retains its credit reservation because the provider may already be generating. A confirmed failure or cancellation restores the credit. Never assume a stopped browser poll means the upstream task failed.
Choose 5, 10, or 15 seconds and 768p, 1K (1080p), or 2K. If submission is uncertain, continue the saved request instead of starting another.
