Quick answer
Export settings should protect the quality of the edit without creating an unnecessarily huge file. YouTube re-encodes uploads, so the best result usually comes from a clean master with standard codecs, correct color, stable frame rate and no extra generation loss.
Use the Free Online Shorts Cutter and test one short sample with the same settings before processing a complete video.
Why this workflow matters
Creators often look for one perfect duration, voice, export preset or automation button. In practice, the best result comes from a sequence of small decisions. The source must contain a complete idea, the active settings must not conflict, and the finished file must be reviewed in the same conditions as the audience will experience it.
Automation is most useful when it makes the workflow repeatable. It should not remove editorial judgment. A mathematically valid clip can still begin in the middle of a sentence, and a technically valid voice file can still pronounce a name incorrectly. The steps below keep speed and quality in the same process.
Recommended starting settings
| Setting | Practical starting point |
|---|---|
| Container | MP4. |
| Video codec | H.264 High Profile is a practical compatible choice. |
| Resolution | 1080×1920 for a common vertical Full HD master. |
| Frame rate | Same as source: commonly 24, 25, 30, 50 or 60 fps. |
| Audio | AAC, 48 kHz, with clear speech and no clipping. |
| Color | BT.709 for standard dynamic range workflows. |
These are starting points rather than universal rules. Content type, language, audience, source quality and platform changes can require a different choice.
Step-by-step workflow
Step 1: Set the final canvas to 9:16 for a full-screen vertical Short
Set the final canvas to 9:16 for a full-screen vertical Short.
Step 2: Use 1080×1920 unless the project has a clear reason for another resolution
Use 1080×1920 unless the project has a clear reason for another resolution.
Step 3: Export progressive video, not interlaced footage
Export progressive video, not interlaced footage.
Step 4: Use MP4 with H
Use MP4 with H.264 and AAC for broad compatibility.
Step 5: Keep the frame rate the same as the recorded or edited source
Keep the frame rate the same as the recorded or edited source.
Step 6: Review the exported file for captions, crop, loudness and sync before upload
Review the exported file for captions, crop, loudness and sync before upload.
How the BestAI tool handles it
BestAI's free Shorts Cutter keeps the length logic explicit. Normal mode uses the main Clip Duration with minimum and maximum length rules. Exact Duration mode takes authority and temporarily disables the conflicting controls. Manual clip count requests a fixed batch, while automatic count splits the selected range into full sequential clips. The live Clip Plan should be checked before processing.
The important design principle is that one setting should control one decision. When a mode overrides another setting, the interface disables the conflicting control and the backend follows the same rule. This prevents a page from showing one plan while processing another.
Quality-control checklist
- Watch or listen from the beginning without reading the source script.
- Check the first two seconds for clarity and unnecessary delay.
- Verify names, numbers, mixed-language words and technical terms.
- Review the result on headphones and an ordinary phone speaker or phone screen.
- Confirm that the final title and description accurately represent the content.
- Keep the original source and a clean master so the project can be revised later.
Common mistakes to avoid
- Exporting a low-bitrate preview file as the final master.
- Changing 30 fps footage to 60 fps without creating useful new motion information.
- Using full-range or unusual color metadata without checking the result.
- Allowing music to mask speech on phone speakers.
- Uploading without watching the final file from start to finish.
A repeatable publishing workflow
Create a small test first. Name the settings or save them in the browser when the tool supports that option. Produce a limited batch, review the files, and change only one important variable at a time. This makes it possible to understand whether duration, crop, voice, speed, subtitles or source selection caused the difference.
For a series, document the chosen ratio, duration range, voice, speed, subtitle style and export format. Consistency reduces production time, but it should not force every topic into an unsuitable length or tone. The viewer's understanding remains the final test.
Frequently asked questions
What bitrate should I use?
YouTube publishes recommended upload bitrate ranges by resolution and frame rate. Use those as a reference rather than forcing one number for every project.
Should I export 60 fps?
Use 60 fps when the source and edit genuinely use high-frame-rate motion. Otherwise preserve the original frame rate.
Does BestAI export MP4?
The Shorts workflow produces compatible video outputs; review the finished file before publishing.
Final takeaway
The strongest workflow is not the one with the most automation. It is the one that makes the creative decision clear, applies the correct setting, produces a test quickly and leaves enough control for a human review. Use the tool to remove repetitive work, then spend the saved time improving the opening, accuracy and final experience.
