[Core Function] Gemini Omni Flash Video Edit performs conversational, instruction-driven editing of an existing video via the Interactions API. [Strengths] It applies natural-language edits (changing the scene, mood, style, lighting, background, or time of day) to an input video while preserving the source video's length and aspect ratio, with synchronized audio. [Best For] Highly recommended for: re-styling or re-lighting an existing clip, changing a video's setting or atmosphere, and quick instruction-based revisions of a short video. [Limitations] Do NOT use this model to generate a video from scratch (use T2V, I2V, or R2V), and do NOT expect to change the output resolution, aspect ratio, or duration: the output preserves the source video's aspect ratio and length, and the model does not accept aspectRatio or duration parameters. The source video should be 3 to 10 seconds. [Routing] Choose this only when the user provides an existing video to modify. To create a new video from text or images, use Gemini Omni Flash T2V, I2V, or R2V instead.
[Core Function] Gemini Omni Flash R2V (Reference-to-Video) generates a short 720p video guided by up to three reference images via the Interactions API. [Strengths] It fuses the styles, subjects, or elements from multiple reference images (referred to in the text prompt) into a single coherent animated clip with synchronized audio. [Best For] Highly recommended for: blending characters or visual styles from several images, reference-guided creative shots, and multi-subject compositions where the prompt directs how the references combine. [Limitations] Do NOT use this model if you only have a single starting frame (use I2V instead), or if you need 1080p or 4K or clips longer than 10 seconds; it accepts 1 to 3 reference images and outputs 720p up to 10 seconds (16:9 or 9:16). [Routing] Choose this when the user supplies multiple reference images to combine into one video. For single first-frame animation use Gemini Omni Flash I2V; to modify an existing video use Gemini Omni Flash Video Edit.
[Core Function] Gemini Omni Flash I2V is a fast Image-to-Video model that animates a single input image into a short 720p video via the Interactions API. [Strengths] It uses the provided image as the opening frame and generates smooth motion with natively synchronized audio at low latency. [Best For] Highly recommended for: bringing a still photo to life, quick product or portrait animation, and short social clips derived from a single image. [Limitations] Do NOT use this model if you need 1080p or 4K output, clips longer than 10 seconds, or the fusion of multiple reference images; it takes exactly one image and outputs 720p up to 10 seconds (16:9 or 9:16). Do NOT use it to edit an existing video. [Routing] Choose this when the user provides one image to animate. To fuse multiple reference images use Gemini Omni Flash R2V; to edit an existing video use Gemini Omni Flash Video Edit; for 4K cinematic results use Veo 3.1 I2V.
[Core Function] Gemini Omni Flash T2V is Google's fast multimodal Text-to-Video generation model built on the Interactions API. [Strengths] It quickly turns a text prompt into a short 720p video with natively synchronized audio, offering low latency and solid prompt adherence. [Best For] Highly recommended for: rapid text-to-video prototyping, short social and marketing clips, quick concept visualization, and cases where speed and built-in audio matter more than 4K cinematic detail. [Limitations] Do NOT use this model if you need 1080p or 4K resolution or clips longer than 10 seconds; output is fixed at 720p, capped at 10 seconds, with aspect ratio limited to 16:9 or 9:16. [Routing] Choose this model when the user emphasizes 'fast', 'quick', or short multimodal clips with sound. If the user demands maximum cinematic quality, 4K, or longer videos, choose Veo 3.1 T2V instead.
**[Core Function]** SkyReels Lip Sync (retalking) re-drives a talking video so the subject's lips match a given audio track. **[Strengths]** Accurate lip re-synchronization on an existing talking-head video. **[Best For]** Dubbing, re-voicing talking-head video, and localizing spoken video. **[Limitations]** Do NOT use this to generate new motion or content from scratch; it only re-times lips on an existing video. Requires video_url and audio_url. Output resolution is fixed at 720p. **[Routing]** Provide the source video_url and the target audio_url; optionally provide reference_char_url to guide the driven face.
**[Core Function]** SkyReels Shot-Switching Extension continues a video while transitioning to a new shot or camera angle. **[Strengths]** Cinematic shot transitions (cut-in, cut-out, reverse-shot, multi-angle, cut-away) when extending footage. **[Best For]** Adding a new shot after existing footage and cinematic transitions. **[Limitations]** Do NOT use this for a plain single-shot continuation (use video-extension-single-shot) or for generation from scratch. Requires a prefix_video (mp4 URL); adds 2-5s. **[Routing]** Provide prompt and prefix_video; choose cut_type for the transition style, or Auto to let the model decide.
**[Core Function]** SkyReels Single-Shot Extension continues an existing single-shot video, generating additional seconds guided by a text prompt. **[Strengths]** Seamless single-shot continuation of the existing motion and scene. **[Best For]** Lengthening clips and continuing an action within one continuous shot. **[Limitations]** Do NOT use this to create a video from scratch (use skyreels-t2v) or to switch shots / add transitions (use video-extension-shot-switching). Requires a prefix_video (mp4 URL); adds 5-30s. **[Routing]** Provide prompt and prefix_video; set duration for how many seconds (5-30) to append.
**[Core Function]** SkyReels Restyle re-renders an existing video into a preset visual style. **[Strengths]** Consistent style transfer across all frames into a chosen named art style. **[Best For]** Turning footage into simpsons, lego, paper-cutting, amigurumi, animal-crossing, van-gogh, or pixel-art looks. **[Limitations]** Do NOT use this to change content, motion, or add new scenes; it only restyles an existing video (input <=30s). Output resolution is fixed at 720p. **[Routing]** Provide the source video_url and a style_name from the supported list.
**[Core Function]** SkyReels Omni is a reference-driven video model that generates or edits video using reference images (@image) and/or a reference video (@video), bound by tags in the prompt. **[Strengths]** A single endpoint covers motion reference, subject/background replacement, object insertion/removal, local editing, and video extension. **[Best For]** Video subject or background swap, motion transfer onto an image, object add/remove, local video edits, and extending a reference video. **[Limitations]** Do NOT use this for pure text-to-video (use skyreels-t2v) or simple single-image animation (use skyreels-i2v). Each ref tag must appear in the prompt as @tag; ref_videos supports only one video (<=15s); a reference-type video may combine only with image-type ref_images, while an extend-type video cannot combine with ref_images. When ref_videos is provided, aspect_ratio is ignored (output matches the video). **[Routing]** Provide ref_images (type grid or image) for image references and/or a single ref_videos entry (type reference for motion/edit, type extend for continuation); the reference tags must be used in the prompt.
