Otherwise we get the classic back-and-forth: &#8220;Can you share more details?&#8221;<\/p>\n\n\n\n<p>Here&#8217;s the support packet we send (copy this):<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Date\/time + timezone of the generation<\/li>\n\n\n\n<li>Project\/workspace name (if applicable)<\/li>\n\n\n\n<li>Mode: T2V \/ I2V \/ reference<\/li>\n\n\n\n<li>Model: the exact Q3 model name shown in the UI<\/li>\n\n\n\n<li>Prompt: full text<\/li>\n\n\n\n<li>Negative prompt: full text (if used)<\/li>\n\n\n\n<li>Seed: include it if visible (huge for reproducibility)<\/li>\n\n\n\n<li>Settings: duration, aspect ratio, fps, motion strength, reference strength, anything you touched<\/li>\n\n\n\n<li>Inputs: uploaded image\/video filename(s), source audio filename(s)<\/li>\n\n\n\n<li>Output ID \/ job ID (if the app shows one)<\/li>\n\n\n\n<li>What went wrong (one sentence): &#8220;Prompt ignored, kept generating a different subject,&#8221; &#8220;flicker every 6\u201310 frames,&#8221; &#8220;audio drifts after 2 seconds,&#8221; etc.<\/li>\n\n\n\n<li>What you already tried: 2\u20133 bullets (so they don&#8217;t suggest the same steps)<\/li>\n<\/ul>\n\n\n\n<p>Trust note (because we&#8217;re all professionals here): if the prompt or inputs contain sensitive client info, we anonymize before sending. Swap brand names for placeholders, blur private images, and avoid uploading anything you don&#8217;t have rights to use.<\/p>\n\n\n\n<p>For where to file issues and what fields they request, we reference the <strong><a href=\"https:\/\/www.vidu.com\/help-center\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">official Vidu Help Center<\/a><\/strong> first, since that&#8217;s the most likely place their current support flow is documented.<\/p>\n\n\n\n<p>Before we go, what&#8217;s the most annoying failure mode you&#8217;re getting right now: prompt ignored, flicker\/warp, or audio? If you tell us your exact mode (T2V\/I2V\/reference) and the one-line prompt, we can suggest the smallest change to try next.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Frequently Asked Questions<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Why is Vidu Q3 not working even though the job says it completed?<\/strong><\/h3>\n\n\n\n<p>When <strong><a href=\"https:\/\/www.vidu.com\/vidu-q3\" target=\"_blank\" rel=\"noopener\">Vidu Q3<\/a><\/strong> &#8220;completes&#8221; but the output is unusable, it&#8217;s often not a hard failure\u2014it&#8217;s a prompt\/settings mismatch, mode mismatch, or account\/traffic issue. Run a known-good test prompt, check credits\/queue behavior, then lock variables (model, duration, FPS, aspect ratio) before changing anything else.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How do I troubleshoot &#8220;prompt ignored&#8221; in Vidu Q3 not working situations?<\/strong><\/h3>\n\n\n\n<p>Start by shrinking your prompt to one subject, one action, and one style, with critical details first. Remove contradictions and temporarily delete the negative prompt to see if it&#8217;s over-restricting. If you&#8217;re using reference inputs, reduce reference dominance (or switch modes) so the prompt can steer results again.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What&#8217;s the best way to fix flicker, warping, or bad faces\/hands in Vidu Q3?<\/strong><\/h3>\n\n\n\n<p>Keep generations simple: one scene and one camera move, with lower motion intensity to reduce distortion. For faces\/hands, begin with a mid-shot, describe hands plainly (e.g., &#8220;hands resting on the table&#8221;), and avoid crowds. Many teams generate a clean version first, then attempt a hands-in-frame variant.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How can I fix noisy or off-sync audio when Vidu Q3 <\/strong><strong>isn<\/strong><strong>&#8216;t working properly?<\/strong><\/h3>\n\n\n\n<p>Use short, simple audio and reduce competing visual motion\u2014fast cuts and big camera moves make sync feel worse. If you upload audio, use clean source files (no background music, minimal reverb). For precise lip-sync, consider generating visuals first and doing lip-sync in a dedicated tool afterward.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>When should I switch modes (T2V vs I2V vs reference) if <a href=\"https:\/\/www.vidu.com\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Vidu Q3<\/a> is not working?<\/strong><\/h3>\n\n\n\n<p>Switch modes based on the symptom. If prompts feel ignored in T2V, move to I2V with a strong starting frame. If identity drifts, use reference inputs for consistency. If flicker comes from &#8220;too much happening,&#8221; start with I2V and ask for subtle motion\u2014fewer invented variables usually means fewer surprises.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Last Thursday night, 14 hours before a major campaign delivery, my entire AI video pipeline broke down.
