AI Video Highlights: Create Reels Faster with AI
AI video models don't pull highlights out of long footage on their own, but they can speed up every other step. Here is a practical highlight-reel workflow using Seedance 2.0, Kling 3.0, music, and auto captions.
TL;DR
Generative models like Seedance 2.0 and Kling 3.0 create new footage; they don't automatically find highlights in a long recording, and Flixly has no automatic highlight extractor. Pick your moments first, then use Image to Video and First to Last Frame for extra shots and transitions, Music Generation for a soundtrack, and Auto Captions for a captioned vertical reel.
Many creators assume one AI button can take a long recording, find the best moments, and return a finished reel. Generative video models don't work that way.
Clip finders analyse existing footage and cut it. Generative models like Seedance 2.0 and Kling 3.0 create new footage from a prompt, an image, or references; they don't scan an upload for action windows, and Flixly has no automatic highlight extractor. The faster workflow: you choose the moments, and AI produces the extra shots, transitions, music, and captions.
A practical highlight-reel workflow
- Pick the moments. Trim your best few seconds from the source footage in any editor. Reels, TikTok, and YouTube Shorts are vertical (9:16), so frame for that.
- Clean up real footage. Use the Upscaler or Stabilizer in Video Tools for clips that are soft or shaky.
- Generate accent shots. Grab a still from a key moment and animate it with Image to Video, for example a slow dramatic push-in. Seedance 2.0 and Kling 3.0 both support 9:16.
- Build transitions. Use First to Last Frame with Seedance 2.0 to generate a transition between two stills from your footage.
- Add music. Create a track in Music Generation and trim it to the length of your cut.
- Caption it. Run the assembled reel through Auto Captions, which returns a captioned version of the video.
Common workflow errors
Users often skip the reference frame. When you animate a moment, start from an actual still of that moment; a text-only prompt invents its own framing and loses the look of your footage. To keep a person or product consistent across several generated shots, use Reference to Video with a model that supports it, such as Seedance 2.0 or Veo 3.1.
Another frequent issue is mismatched audio length. A generated track rarely matches your cut exactly, so trim or fade it in your editor instead of leaving silence at the end.
Finally, don't expect generated clips to reproduce real events. Use them for intros, transitions, and emphasis, not to replace the real play.
Model comparison table
| Model | Modes | Durations | Resolutions | Credit cost |
|---|---|---|---|---|
| Seedance 2.0 | Text, image, reference, first-to-last frame | 4s to 15s | 480p to 4K | Quoted in-app |
| Kling 3.0 | Text, image | 3s to 15s | 720p, 1080p, 4K | Quoted in-app |
| Veo 3.1 | Text, image, reference | 4s, 6s, 8s | 720p, 1080p, 4K | Quoted in-app |
All three support 9:16. Seedance 2.0 is the most flexible here thanks to reference and first-to-last-frame modes.
Setting the right parameters
Use Lip Sync for talking segments with dubbed audio; it aligns mouth movement in a video to an audio track. Apply Auto Captions last, once the cut and music are locked.
Verifying output quality
Play the reel on a phone. Check that cuts land on the beat, captions stay readable and clear of on-screen buttons, and the action stays near the centre of the frame. If a shot lingers too long, trim it or regenerate with more movement in the prompt. If a transition doesn't match, regenerate it from stills closer to the cut points.
Start creating your accent shots in the Video Generator.
Frequently Asked Questions
Can Flixly automatically pull highlights out of long footage?▾
No. Flixly's video models generate new footage from prompts, images, or references; they don't scan an upload and pick the best moments. Choose your segments first, then use AI for extra shots, transitions, music, and captions.
Which model works best for highlight-style shots?▾
Seedance 2.0 is the most flexible for highlight-style shots because it supports image-to-video, reference-to-video, and first-to-last-frame modes. Kling 3.0 is a good option for animating a single still. Compare the in-app credit quotes before generating.
How do I add auto captions to a highlight reel?▾
Upload the finished reel to Auto Captions, which returns a captioned version of the video. Do this last, after the cut and music are final, so the captions match the finished audio.
Can I reuse the same music track across multiple highlight reels?▾
Yes. Generate a track in Music Generation, download it, and trim it to each reel's length in your editor. If a reel runs longer than the track, Music Tools can extend it.
