# Common Errors Source: [Common Errors]() Documentation index: [llms.txt]() Last updated: 2026-10-19 Start with the exact message shown in the editor. ChatCut reports immediate validation near the control you used, longer-running generation failures on the asset card in **My Assets**, and account or credit issues in a dialog. ## Where should I look for the error? - **Composer or toast**: invalid files, missing prompt, unsupported input combinations, and settings that need correction before sending. - **My Assets**: progress and final status for video, image, music, and other generation jobs. Open the failed card for its message. - **Export panel**: unsupported export options, browser limitations, and render failures. - **Avatar → Credits history**: credit balance, transactions, subscription, and payment actions. ## Why is the Send button disabled? Hover the button and read its tooltip. Common causes include a missing first frame, a last frame without a first frame, missing source video, missing edit/extension prompt, unsupported audio-only references, or a source outside the allowed duration. Add or replace the requested input. ## Why was a reference removed or rejected? Confirm the selected model and input mode. Switching models keeps only compatible media. Remove extra files, convert unsupported formats, shorten an overlong source, or choose a model that accepts that media type. See [Video Generation Models](https://pr-523-preview.chatcut.dev/docs/video-generation-models). ## Why does a feature ask me to upgrade? The current account does not have access to that feature or capacity. Select **Upgrade** in the dialog to review current options. If you already upgraded, refresh the project and reopen the action. If access is still wrong, contact support with the account email and a screenshot of the dialog. ## What if I have insufficient credits? Open the avatar menu and select **Credits history** to check the balance and recent transactions. Add or renew credits using the options shown there, then submit again. Do not repeatedly retry a request that already has an active job in **My Assets**. ## What if generation fails after it starts? Read the failed asset card. Provider safety checks, temporary service problems, and output processing errors can happen after submission. Follow the card’s specific instruction: revise the named prompt or reference, retry later, or regenerate. Use the credit transaction shown in **Credits history** to verify whether any charge was retained; do not infer billing from the error category alone. ## What if my project cannot open? Keep the original project and any existing backup unchanged while the problem is assessed. Record the exact opening error, your ChatCut version and operating system, and whether the failure happens when opening the original, duplicating it, or both. If the message mentions a source occurrence or translated captions, include the exact wording rather than deleting captions or changing the timeline to make the error disappear. Contact support through the existing [Contact](https://pr-523-preview.chatcut.dev/docs/contact) route. Describe the result you need to preserve, including the affected timeline and important audio, caption, timing or layout requirements. If support requests a diagnostic report or project backup, check that the files are actually attached; for large files, use a private link shared only with the support recipient. Keep account credentials and login caches out of the report. A recovery method or fixed version needs to be confirmed for the reported case. A successful export, duplicate or reconstructed clip does not by itself establish that the original editable project has been recovered. ## When should I contact support? Contact support after the same valid input fails repeatedly, a completed payment does not update access, a project cannot reopen, or an export fails after retrying with standard settings. Include the account email, project URL, approximate time, exact message, browser or desktop version, and a screenshot. Do not send private payment credentials or unnecessary source media.
