Carry a visual idea from your reference images into a moving shot. Start with text, guide the first and last frames, or combine references for a 3–30-second draft.
Kling 4.0 in FireRed Image Edit gives you several starting points for a video: a written shot brief, a first image with an optional last image, or a set of visual references. Use those inputs to explore product motion, character actions or a storyboard sequence. Choose 720p or 1080p and evaluate the draft across its full timeline before building your final edit.
Separate frame planning, reference preparation and output review.
Think about the role of the clip in your edit: a product reveal, a character reaction or a transition between storyboard moments. Name the subject, action and camera movement in the brief. Text-to-video does not need an upload. For a complex sequence, test one movement first; exact typography and detailed choreography can require further work.
For frame generation, upload a first image and optionally a final image. The current FireRed selector accepts JPG, PNG and WebP images up to 30 MB. Reference mode supports up to 10 images and one 2–30-second video. Identify the materials with @image_1 or @video_1 and upload video to FireRed first. A reference guides a new shot rather than directly editing the source clip.
Available output is 720p or 1080p for a whole-second duration from 3 to 30 seconds; the default is five seconds at 720p. Text and reference workflows offer 16:9, 9:16, 1:1 and 21:9, with automatic framing where the selected mode supports it. First/last-frame generation follows the first image. Prepare that crop in advance; 4K output is not available here.
Sign in, choose text, frame or reference input, then describe what should happen and any relevant sound. Confirm the displayed settings and credit total before submitting once. Kling can generate native audio, but FireRed has no separate sound switch, voice upload, intermediate-keyframe editor or reusable character library for this model. Track the task status, then inspect the completed draft.
The KIE route costs 171 credits for five seconds at 720p without a video reference, or 255 at 1080p. A video reference adds input time: billed seconds equal output duration plus the greater of input and output duration. For example, a three-second reference and five-second output cost 204 credits at 720p. Read the revised estimate after changing inputs or settings.
Compare the result with your references from beginning to end. Watch for changing faces, product proportions, drifting backgrounds, unexpected text and abrupt motion; listen to the sound as well. Download and open the file before placing it in your timeline. Add exact graphics and final cuts in your editor. Processing time and fidelity vary, and your reference material must be appropriate for your intended use.

Plan Your Next Video with Kling 4.0 FAQ
Use text when you are exploring a shot without fixed artwork. Use frames when the opening image matters and you may want an ending image. Use reference mode when several images or a video should guide a new generation. Keep the subject and movement clear in every mode.
Upload the first image and, if needed, a final image. The current FireRed controls accept JPG, PNG or WebP up to 30 MB. Crop the first image to your intended composition because it sets the frame. Intermediate keyframes are not exposed in this workspace.
Reference mode accepts up to 10 images and one video lasting 2–30 seconds. Refer to them with @image_1, @image_2 or @video_1. Upload the video to FireRed before submission. It guides a new clip and contributes to the price; it does not turn this into a direct source-video editor.
Choose a whole-second duration between 3 and 30 seconds and either 720p or 1080p. The starting setting is five seconds at 720p. There is no 4K output setting for Kling 4.0 here.
Yes. Text and reference workflows include 9:16 and 21:9 alongside 16:9 and 1:1. Automatic framing depends on the selected input workflow. First/last-frame output follows the first image, so set its crop before uploading.
Video-reference pricing includes the output plus the greater of the input and output durations. A five-second output without video references costs 171 credits at 720p or 255 at 1080p; a three-second reference with five seconds of output costs 204 at 720p. Always check the current estimate.
Native audio may be generated, but this workspace does not provide a separate sound switch, voice uploads, intermediate keyframes or a reusable character library for Kling 4.0. The available controls are the features offered here, which may differ from the wider Kling platform.
It is supplied promotional media for the model. The FireRed cover is original AI artwork. Neither is evidence of a generation task performed on this site. Use your own draft to assess continuity, sound and reference accuracy before relying on it in a final edit.
Choose the input workflow, prepare your images or video and describe the movement. Review the duration, resolution and credit estimate before you submit.
