The **Video Generation** node turns a written idea, or a starting image, into a generated video. Think of it like a video production assistant that takes your brief and returns a ready-to-use clip for campaigns, demos, or social content. It works for both text-to-video and image-to-video workflows. #### Smart features * **One node for two creation styles**: start from a prompt alone, or use one or two images to guide the result. * **Automatic image role handling**: if you add two images, Diaflow treats them as the start frame and end frame for a smoother transition. * **Built-in video finishing options**: you can turn on **Enhancement** and **Compression** to improve quality and reduce file size. * **Optional last-frame output**: you can return the final frame as an image and use it to continue the next video segment. * **Flexible input mapping**: pull prompts and images from earlier nodes without manual re-uploading. * **Automatic cleanup of unsupported values**: if frame rate or duration settings are outside the supported range, Diaflow adjusts them to a valid value.
### Real-World Business Value * Turn a campaign brief into a short promo video for ads, landing pages, or social posts. * Animate a product image into a motion teaser without sending work out to a video team. * Create connected video scenes by using the last frame from one clip as the starting point for the next clip. ### Step-by-Step Setup * In **Model**, choose the video model you want to use. * In **Prompt**, describe the scene, motion, style, lighting, and camera feel you want. * In **Image source**, add one image if you want the video to begin from a specific visual, or add two images if you want Diaflow to guide both the first and last frame. * In **Resolution**, select the output quality that matches your chosen model. * In **Aspect ratio**, choose the shape that fits your channel, such as **16:9** for landscape or **9:16** for vertical. * In **Duration**, enter the clip length in seconds. * In **FPS**, choose **24**, **30**, or **60** depending on how smooth you want the motion to feel. * Turn on **Camera Fixed** if you want the camera position to stay locked. * If your selected model supports it, turn on **Audio** to generate sound with the video. * Turn **Enhancement** on if you want Diaflow to improve video quality after generation. * Turn **Compression** on if you want a smaller final file size. * Turn on **Return Last Frame** if you want to reuse the ending image in a later video step. * Run the workflow and review the result in the **Output** tab. ### The Transformation: Before & After **Before basic campaign request**
**After generated video result**
If **Return Last Frame** is on, the result can include both the video and the final frame image. ### Tips & Warnings for First-Timers #### Best practices * Write prompts that describe both the scene and the motion. * Match **Aspect ratio** to the final channel before you generate. * Use one image for a guided starting frame. * Use two images only when you want Diaflow to connect a beginning and an ending scene. * Turn on **Return Last Frame** when building multi-part video sequences. #### Warnings * Do not add more than two images in **Image source**. Extra images are ignored. * Do not choose **1080p** with models that only support lower resolutions. * Do not expect very short durations to stay unchanged on every model. Some models raise short values to their minimum supported length. * Do not assume video generation is fast. Longer clips, finishing options, and uploads can take several minutes. * Do not assume **Enhancement** and **Compression** always run. If that finishing service is unavailable, Diaflow may return the original video instead. * Do not assume every public workflow output stays available forever. Some public video links may expire. * Do not hide image links inside the **Prompt** unless you want them treated as image input. * Do not use unsupported image files as video input. Convert files like PDFs into images first. * Do not expect the output to be a permanent public video link. The result is typically a stored workflow file reference. ### Need help? * Learn the basics in [How a node works](/getting-started/lets-start-with-the-basics/how-a-node-works.md) * Build the full flow in [Create a workflow](/workflow-builder/create-a-workflow.md) * Browse related nodes in [Component List](/workflow-builder/component-list.md)
