What is the difference between text-to-video and reference-led video?
With text alone, the AI Video Generator interprets both the scene's appearance and its movement from your description. A reference image gives it additional visual direction. You still need to describe the action, camera, and ending. A reference does not automatically turn the entire image into an exact animated version, and the result may change details.
How long should an AI video prompt be?
Long enough to identify the subject, action, setting, camera, and important constraints. Remove details that do not affect the shot. A focused paragraph often gives you a clearer revision path than several disconnected instructions. The prompt limit is shown in the tool. Use the available space to explain the video, not to repeat quality adjectives.
Can I use more than one reference image?
Check the selected model's reference controls and limits. When several images are supported, give each a clear role, such as the main subject or the environment. Conflicting appearances can make the video harder to direct. Start with the references essential to the shot, then review whether the generated clip uses them in the way you intended.
Why does my generated video change the subject?
Generative models may reinterpret faces, textures, clothing, and objects as they create motion. Reduce the number of competing actions, keep the subject description consistent, and use a clear reference where supported. Generate a revised clip and compare the whole video. There is no prompt that guarantees perfect identity across every frame and every model.
Can the AI Video Generator create dialogue and sound?
Audio capabilities depend on the selected model and current settings. Keep dialogue short, make the speaker clear, and listen to the result before publishing. Check timing, pronunciation, and whether the sound matches the visible action. If the desired sound is not supported or the result is unsuitable, plan a separate audio step in your editing workflow.
How do I create a longer video?
Divide the idea into shots with a clear order. Generate and approve each clip, then assemble the selected videos. Keep recurring descriptions, references, and visual choices consistent across the sequence. The AI Video Generator creates individual clips; it does not turn every multi-scene prompt into a finished edited film. Our MP4 merger can join compatible finished clips.
How should I compare models and generation costs?
Use the same intended shot and comparable settings, then judge usable results rather than model names alone. Check the displayed credit quote before every video generation. Different models and settings can change the available controls and cost. If your task is a straightforward fruit scene, the Simple workspace offers a more guided place to start.
