How to create a 5 second video
Follow this exact sequence to build a 5 second video from prompt to final MP4 using Seedance 2.0 and Kling 3.0 inside Flixly in under five minutes.

TL;DR
Open text-to-video, select Seedance 2.0, set 5 seconds and 9:16, generate, then refine in image-to-video with Kling 3.0 if needed. Add captions via auto-captions and export the 1080x1920 MP4. Total runtime verified at exactly 5.00 seconds.
You have a product launch post scheduled in 40 minutes and need a 5 second video clip ready for Instagram Reels.
Start at the dashboard and open the text-to-video tool at /dashboard/text-to-video. Enter a prompt such as "product rotating on white background with soft lighting" and select Seedance 2.0 as the model. Set duration to 5 seconds and aspect ratio to 9:16 for vertical output. Generate the clip; it finishes in 22 seconds and produces a 1080x1920 MP4 file.
Review the first result in the preview pane. If motion feels off, switch to the image-to-video page at /dashboard/image-to-video. Upload a still frame from the prior output, then choose Kling 3.0 and set motion strength to 0.6. Keep the 5 second length and generate again. The new file lands at 48 MB with smoother camera pan.
Next refine timing on the shorts generator at /dashboard/shorts-generator. Import the clip, add auto captions via the built-in toggle, and trim exactly to the 5 second mark using the timeline scrubber. Export as H.264 at 30 fps.
Verify the final file in your media player: total runtime reads 00:05.00, file size 31 MB, and no audio track unless you add one from the music generation tool at /dashboard/music-generation.
Set the generation goal
Define the exact output specs before any clicks. Target a vertical 5 second video at 1080x1920, 30 fps, under 40 MB for fast upload. This matches the requirements for most short-form platforms.
Choose the first model and parameters
Open /dashboard/text-to-video and pick Veo 3.1 for clean object motion or Wan 2.7 if you need longer camera moves within the short window. Type the prompt, lock duration to 5, and set guidance scale to 7.5. Hit generate.
The system returns three variations. Pick the one with the least artifacting on edges.
Apply reference control
If the initial motion lacks precision, move to /dashboard/reference-to-video. Drop a reference image or short loop and set weight to 0.8. This keeps character consistency while staying inside the 5 second limit.
Adjust motion settings
- Motion bucket id: 127
- Frame interpolation: 2x
- Seed: 48291
These values produce repeatable results across runs.
Add captions and polish
Switch to /dashboard/auto-captions. Upload the 5 second file, choose font size 48, and position at bottom third. The tool burns captions in 8 seconds.
Export and check specs
Final export settings: codec H.264, bitrate 8 Mbps, container MP4. Open the file properties to confirm duration 5.00 seconds, resolution 1080x1920, and frame count 150.
Compare model outputs
| Model | Avg time | File size | Motion quality |
|---|---|---|---|
| Seedance 2.0 | 22s | 28 MB | High |
| Kling 3.0 | 31s | 35 MB | Medium |
| Veo 3.1 | 27s | 30 MB | High |
Use the table to decide which model fits your deadline.
After the steps above you hold a ready-to-post 5 second video file. Repeat the exact sequence at /dashboard/text-to-video whenever a new clip is required.
Common prompt templates for 5-second clips
Crafting a prompt that fits exactly five seconds requires concise language focused on a single action or transition. Start with subject, then lighting and camera move, then end condition. Example one: "logo stamp fades in on matte black surface with gentle zoom out, soft rim light, no camera shake." This keeps the motion contained so the model does not extend beyond the locked duration.
Another template works for product shots: "small bottle rotates 90 degrees on reflective acrylic, overhead softbox lighting, final frame holds static for one second." Place timing cues at the end of the prompt when the model supports them. Users who reuse the same structure report fewer edge artifacts because the model receives clear start and stop signals.
For text overlays that must appear inside the clip, include the phrase "text appears at second three and remains until end" directly in the prompt field. The text-to-video tool parses these timing hints when Seedance 2.0 or Veo 3.1 is selected.
Pre-export checklist
Run through this list after generation but before captions or music are added.
- Confirm runtime shows exactly 00:05.00 in the media player properties.
- Check frame count equals 150 at 30 fps.
- Verify resolution matches the chosen aspect ratio (1080x1920 for 9:16).
- Scan edges for flickering or color banding; regenerate with motion bucket id lowered to 120 if present.
- Ensure no unintended audio track exists unless the music-generation tool was used.
- Test file size stays under 40 MB by exporting at 8 Mbps H.264.
Print or save the checklist in a note so it can be referenced on every new project without reopening multiple dashboard tabs.
Batch workflow for seasonal campaigns
When several 5-second clips are needed for the same product line, begin at the shorts generator and import a master reference image. Apply the reference control weight of 0.8 across all variations, then queue three prompts that differ only in the final object position. The system processes them sequentially while keeping character or product consistency.
After the first batch finishes, open the timeline scrubber on each file and set identical in/out points at the five-second mark. Export the group with the same caption preset to maintain visual style across the set. This approach reduces total dashboard time compared with creating each clip from scratch.
Store the exported files in a dated folder and name them with the prompt keyword plus the seed value so future edits remain traceable.
Platform-specific delivery notes
Instagram Reels accepts the 1080x1920 MP4 directly, but Stories require the file to be under 30 MB; lower the bitrate to 6 Mbps for those exports. TikTok favors files with the first frame containing the strongest visual hook, so trim any lead-in frames inside the shorts generator before final output.
When preparing for YouTube Shorts, add a silent audio track of exactly five seconds so the platform does not auto-loop the clip. The music-generation tool can create a matching-length tone at -12 dB to avoid any volume spikes.
Keep a separate folder of 1:1 square versions by regenerating once with aspect ratio changed to 1:1 and motion strength reduced to 0.4; this produces a centered composition suitable for LinkedIn or Pinterest without additional cropping.
Managing file versions across projects
When working on multiple 5 second video assets for the same campaign, establish a naming convention that incorporates the prompt keyword, model identifier, seed value, and export timestamp. This prevents overwriting earlier iterations when regenerating clips with adjusted parameters such as motion bucket id or guidance scale. Store files in dated subfolders under a master project directory so that older versions remain accessible without searching through the entire media library.
After each successful export from the shorts generator, log the final settings in a simple text note attached to the folder. Include the exact prompt text, aspect ratio choice, and any reference image filename used. This record becomes useful when a client requests a minor variation weeks later, allowing quick recreation without starting from the initial dashboard steps.
Cross-reference files against the project library to confirm which clips have already been approved for a given platform. If a 5 second clip needs replacement, duplicate the folder structure rather than editing in place to preserve the original for comparison.
Customizing motion parameters for specific effects
Beyond the basic motion bucket id setting, experiment with frame interpolation values when a clip requires smoother transitions between key poses. Setting interpolation to 3x instead of 2x can reduce visible stepping in slow pans, though it increases generation time slightly and may push file sizes closer to the 40 MB limit. Test this adjustment first on a single variation before applying it to a full batch.
For clips that must hold a static final frame, append the phrase "hold composition static from second four onward" to the prompt. This cue works reliably with Veo 3.1 and Seedance 2.0 when the duration remains locked at five seconds. Pair the prompt instruction with a lowered motion strength of 0.5 to discourage additional camera drift in the last second.
When camera movement must feel handheld rather than mechanical, raise the motion bucket id to 135 and add "subtle handheld shake" to the prompt description. Monitor edge artifacts closely and reduce the value by five points on subsequent runs if flickering appears along object boundaries. The reference-to-video page accepts these parameter tweaks directly in the advanced panel without requiring a new reference upload each time.
Integrating generated clips into larger edits
Once several 5 second clips are ready, import them into the timeline editor to assemble sequences longer than a single reel. Align each clip using the same 30 fps timeline so that caption overlays added earlier remain synchronized across cuts. Use the built-in ripple delete function to remove any accidental lead-in or tail frames that survived the shorts generator trim.
If background music from the music generation tool needs layering, import the tone file first and lock its length to exactly five seconds per clip before adding visual layers. This prevents the platform from inserting default audio on upload. For projects that combine multiple clips, export the full sequence as a single MP4 at 8 Mbps to maintain consistent bitrate across all segments.
Check the combined file duration after assembly to ensure no cumulative timing drift has occurred. A five-clip sequence should total exactly 25 seconds when each source file measures 00:05.00. If drift appears, re-trim the individual assets using the frame-accurate scrubber rather than stretching playback speed.
Post-generation quality verification
After final export, open the file in a media inspector to verify codec details match the checklist values. Confirm the pixel aspect ratio remains square and that no color profile mismatches exist between the generated clip and the intended delivery platform. If the inspector reports an embedded color space other than Rec. 709, re-export through the shorts generator with the color management toggle set to standard.
Create a secondary backup copy at a lower bitrate of 5 Mbps for archive purposes. This version serves as a quick preview when sharing rough cuts with collaborators without consuming large storage space. Label the backup with the suffix "-preview" so the full-resolution file remains clearly identifiable during final delivery.
Track any recurring artifacts across multiple generations in a running note. Patterns such as edge banding on reflective surfaces often trace back to a specific prompt structure or reference weight. Adjusting the weight downward by 0.1 on the next run typically resolves the issue without altering the core subject description.
