FLUX 3 Video searches can lead to three different tasks: making a new shot, editing an existing shot or increasing its output resolution. Start by naming the deliverable. A continuation should add a new beat after the source; an edit should change a defined part of the source; an upscale should be judged on its finishing behavior.
This independent guide uses an original six-second tabletop animation as a practice source. The clip was authored with code and encoded conventionally. It is not a FLUX generation. The request templates have not been submitted, and the guide does not claim measured FLUX quality, timing or cost.
Choose the FLUX operation before copying a request
The current Black Forest Labs overview separates text-to-video, image-to-video keyframes and video continuation from its Video Edit tool. The generation reference names those modes explicitly. Use the operation that accepts your actual starting asset.
| Starting point | Operation | What should happen |
|---|---|---|
| A written shot idea | Text to video | A new scene is generated |
| Approved opening or endpoint images | Image to video with keyframes | The images constrain moments within a new clip |
| A video whose action should continue | Video continuation | A new beat follows the existing action |
| A take with one unwanted element | FLUX Video Edit | A defined change is applied to the source |
| An accepted clip needing finishing | Video upscale | Resolution or detail treatment is reviewed against the source |
Do not turn a video-editing instruction into a continuation request by changing only the prompt. The expected input fields and output behavior differ. For finishing existing footage, use our FLUX and Higgsfield upscale guide, which retains that separate canonical intent.
Separate current documentation from older access notes
The current BFL overview documents up to 20-second output and higher-resolution finishing options, while its older help article lists fewer resolution choices. The overview also separates keyframe control from the still-pending Omni Reference feature. Use the current endpoint schema for the mode and variant you choose.
The model page names FLUX 3 Max. That label does not establish a speed improvement measured by this guide or identical access through every provider. When moving between direct BFL access and Higgsfield, record the service and model as well as the prompt. Interface controls and account credits do not transfer automatically.
Download a source clip with motion you can inspect
Watch this clip and view its details
Download the original six-second silent source. A coral parcel moves slowly across a teal workbench. The amber desk light and camera stay fixed. The source deliberately ends before the parcel leaves the scene, giving a continuation brief a simple next action.
Watch the source before adapting it. Record the parcel's direction, speed, shape, contact with the desk and the position of the lamp. These are concrete continuity checks. The file supplies an actual input to practice with; it does not prove how FLUX will respond.
Download the actual first frame and actual last frame. They are extracted from the encoded source rather than invented replacement endpoints.
Write a continuation brief for the next event
Continue the source shot as the coral parcel moves a little farther to the right across the same teal workbench, then comes gently to rest. Keep the fixed camera, amber desk light, parcel shape and desk contact consistent. One continuous shot. No new objects, opening lid, text or additional action. Keep the output silent.
This original prompt describes only the continuation. It does not repeat the entire source action or ask for a new location halfway through. If the task is preserving a longer story, make a written beat list first so the next generation does not replay an event that has already happened.
Download the unsubmitted continuation request template. Its source URL points to this practice clip. Supply credentials only in your own server environment and confirm access and price before submitting. The download itself makes no API request.
Use keyframes when the visual endpoints matter
Use an image-led operation when you want to constrain the start, end or another supported moment. State what happens between the images. Two incompatible poses or lighting states can still create a difficult transition even when the files are accepted.
Start from the first supplied tabletop frame and move toward the second supplied frame. The coral parcel glides smoothly to the right across the teal desk without rotating. Keep the amber lamp, background and camera fixed. Maintain the parcel proportions and tabletop contact. One continuous silent shot with no extra objects or text.
Download the unsubmitted keyframe request template. It is a separate alternative to continuation, not another stage required after it. Use the endpoint's current accepted fields and record the actual output duration after generation.
Treat a draft as a production decision
BFL documents a draft workflow and a later enhancement step using the returned draft data. Save that returned data with the accepted draft rather than recreating the prompt and assuming you have preserved the same take. A draft approval should include the action, framing and story beat, not only the color treatment.
Recheck the enhanced export. Higher-resolution finishing can expose changed textures, unstable corners or a weak contact moment. The source, draft and final result should remain separately available so the team can explain what was accepted at each step.
Review the join and the full exported clip
Play the source ending and continuation beginning together. Check whether the parcel jumps in position, changes speed, floats or changes size. Then inspect the ending to confirm that it actually settles. A pleasing still frame does not establish a smooth transition.
Use the blank video review sheet to record settings, actual charges and observed issues. For a deeper seam exercise, use the AI video extension guide. For newly directed scenes using independent subject references, compare the reference-to-video guide.
