Work backward from delivery. Choose the target canvas before generating, create short shots with clear cut points, inspect one downloaded clip in a matching CapCut project, and test-export a representative edit before committing to a full sequence.
Do not assume every Seedance 2.0 Mini access route offers the same downloads or settings. Dreamina's documented flow includes text-to-video and image-to-video generation, plus duration and format controls before generation, but the available information does not establish universal Mini container, codec, frame-rate, aspect-ratio, watermark, or licensing settings. Check the current generation screen, download one test clip, and inspect the actual file before producing a large batch.
Start With the Delivery Canvas
Pick one primary destination and build the project around it. This prevents a common failure: generating a wide composition, then discovering that a vertical crop removes the subject, product, or generated text.
A practical starting point is:
- 1
- Vertical social video: 9:16 2
- Square placement: 1:1 3
- Standard horizontal video: 16:9
For TikTok, Instagram Reels, and YouTube Shorts, commonly listed guidance recommends a vertical 9:16 delivery at 1080 × 1920, often with 30 fps and an MP4 or MOV file. YouTube Shorts are also commonly listed as vertical videos no longer than 180 seconds for Shorts-shelf eligibility. Treat these as starting points, not permanent rules: confirm the current official requirements for the platform, account, region, upload method, duration, file size, codecs, and AI-content labeling before delivery.
For a standard horizontal YouTube version, 1920 × 1080 at 16:9 is a useful project target.
Before you generate, write down:
- 1
- Destination platform or client specification 2
- Final aspect ratio and pixel dimensions 3
- Intended duration 4
- Whether captions, logos, product copy, or a speaker must remain in a safe area 5
- Whether a horizontal or square version will also be required
If one campaign needs several formats, make the primary composition first. Generate alternate framing only when the subject, product, or action will not survive a simple crop.
Generate Shots That Can Be Cut
A single long AI-generated sequence can be useful when it works, but separate short shots are usually easier to evaluate, replace, and reorder. They also give you more options in CapCut when one moment contains an obvious artifact.
Build a sequence from individual editorial jobs, such as:
- 1
- Hook: establish the person, product, or setting 2
- Detail: show the key action or feature 3
- Proof: demonstrate a result, use case, or close-up 4
- Reaction: show a response or transition in energy 5
- End frame: deliver a CTA, brand line, or clean closing image
Keep recurring details consistent from shot to shot: subject description, wardrobe, setting, lighting direction, color mood, camera language, and motion direction. A concise prompt structure can help: define the subject, specific action, proof detail, camera movement, lighting or mood, and intended ending. See the Seedance 2.0 Mini prompt guidance for that pattern.
When testing variations, change one variable at a time. Reusing the same seed can make a prompt comparison cleaner, but it is not a guarantee that characters, motion, or results will be identical across generations or settings.
Screen every clip before importing the whole batch
Watch each clip once at normal speed and once while pausing on critical moments. Check for:
- 1
- Flicker or unstable lighting 2
- Warped hands, faces, products, or background objects 3
- Generated text that is unreadable, misspelled, or changes between frames 4
- Subject drift, such as clothing, facial features, or props changing unexpectedly 5
- Jumpy movement, broken physics, or an unusable action 6
- Framing that cuts off the subject in the intended canvas 7
- Embedded audio, unwanted noise, or an audio sync issue 8
- Continuity conflicts with the preceding and following shots
Keep the best available original download, along with the prompt, seed where available, version, source image or reference, and rights notes. That record makes a replacement generation much easier if a client asks for a revision.
One documented ComfyUI integration limits Mini output to 480p and 720p, but that limitation is specific to that integration. Do not assume the same resolution options apply everywhere; inspect the settings and the file from your own access route.
Set Up CapCut With a Test Clip First
Create the CapCut project at the intended delivery canvas before you assemble the edit. Then import one representative clip-ideally a shot with movement, skin tones, fine detail, and any source audio.
Commonly listed video containers for CapCut import include MP4, MOV, and MKV, but container support alone does not confirm compatibility. Codec, device, operating system, and CapCut version can affect whether a file imports and plays correctly. A short test import is more reliable than planning around an assumed format.
Use the test to verify:
- 1
- The clip imports without an error 2
- Playback is smooth enough for editing 3
- The image fills the intended canvas as expected 4
- The crop preserves the key subject and action 5
- Audio is present, aligned, or intentionally muted 6
- The source frame rate is identifiable and consistent across the batch 7
- A short export plays correctly outside the editor
Where possible, match the export frame rate to the original footage. If your timeline combines clips with different frame rates, test the final motion rather than assuming one setting will suit every shot.
If the test clip does not work cleanly, stop before building the full edit. Replace the source, create a compatible conversion from the original file, or adjust the project approach. Avoid repeatedly exporting and re-importing compressed versions as working media.
Edit Around Defects Instead of Enlarging Them
CapCut can help you shape a usable cut, but it cannot be treated as a dependable repair system for generated-video failures. Start with editorial fixes before applying visual adjustments.
Use this repair-or-regenerate decision
Trim first. A clean two-second shot is usually more useful than an unstable five-second shot.
Use reframing, stabilization, sharpening, brightness and contrast adjustments, and speed changes sparingly. These tools can improve an already acceptable shot, but they can also draw attention to warped edges, synthetic texture, jitter, or flicker. Preview every adjustment at full size, especially after sharpening or stabilization.
For multi-shot sequences, review the whole cut without stopping. Watch for changes in:
- 1
- Subject identity and wardrobe 2
- Lighting direction and color temperature 3
- Product shape, packaging, or logo treatment 4
- Camera direction and screen movement 5
- Typography and caption style 6
- Music level, voice level, and transition timing
Add captions after the visual cut is stable. Keep them clear of important visual details and platform interface areas, then test them on the actual target canvas.
Export for the Destination, Then Inspect the Upload
Export one approved master from the final CapCut timeline, retain the project and original sources, and create platform-specific delivery files from that confirmed edit when needed.
*These are third-party guidance points and may change. Confirm current official specifications before publication or client handoff.
For Instagram compatibility, MP4 with H.264 video and AAC audio is commonly identified as a practical quality-to-file-size balance, but that does not guarantee an upload will avoid transcoding. Upload processing can change softness, motion, audio behavior, and caption placement.
Always upload a short representative version as a draft or private test when the platform allows it. Inspect the uploaded result for:
- 1
- Cropping or letterboxing 2
- Caption placement and readability 3
- Softness, blockiness, or motion artifacts 4
- Audio sync and playback 5
- Whether music or sound is missing 6
- Unexpected disclosure, watermark, or publishing notices 7
- Playback on both a phone-sized view and a larger screen
If Instagram audio does not play, unsupported audio or improper synchronization can be a cause; AAC and MP3 are listed as compatible examples in this Instagram video file-format guide. Check the final uploaded post, not only the exported file.
Publish or Deliver Only After This Final Check
Before publishing or sending files to a client, confirm:
- 1
- The project canvas, export dimensions, frame rate, and duration match the destination 2
- No visible AI defect changes a person, product, logo, action, or factual claim 3
- Captions, titles, logos, and CTAs remain readable after upload 4
- Audio is synchronized, audible, and cleared for the intended use 5
- Music, templates, fonts, stock assets, reference images, and client materials have the appropriate permissions 6
- Recognizable people, trademarks, and branded products have been reviewed where relevant 7
- Current platform rules for AI-generated or altered-content disclosure have been checked 8
- The exported file and uploaded result have both been played through in full 9
- The CapCut project, original downloads, and approved final master are archived
Music availability inside an editor does not by itself clear publication on every platform or commercial use. Check the license for the individual track and the applicable platform terms.
Start with one representative Seedance 2.0 Mini clip: create a CapCut project in the target aspect ratio, test the complete source-to-export path, inspect the uploaded result, and then scale the confirmed workflow across the remaining shots.
