Auto Motion Studio detailed guide

This guide separates what Auto Motion Studio can organise automatically from the decisions an editor still makes. Analysis provides a starting point; the result is reviewed and refined on the actual timeline before export.

From imported footage to final export review

Step 1
Prepare media and destinations
Import the video and audio, choose a save location, and confirm the required BGM, narration, and caption setup. A project is created while the source media remains unchanged.
Step 2
Collect review candidates through analysis
Analyse silence, transcription, caption candidates, audio level, and picture quality to organise the places that need editorial judgment. Analysis is the start of editing, not the finished edit.
Step 3
Make human decisions on the timeline
Review cuts, order, captions, B-roll, BGM, narration, colour, and effects against the preview. Switch between Standard Editing, Dual Monitor, and Timeline Focus according to the task.
Step 4
Prepare the thumbnail and release material
Build a thumbnail from candidate frames and, when useful, prepare draft titles or descriptions. Keep the video and its supporting material within the same project.
Step 5
Review the export
Confirm format, resolution, captions, audio, and destination before rendering. If a publishing connection is used, also check the destination, visibility, schedule, and content.

Practical use cases

Reduce preparation work for a YouTube edit

Organise silence and caption candidates in longer footage, then retain and refine the right sections on the timeline.

Create a short vertical version

Keep the original edit while adjusting a 9:16 composition and checking whether captions and the important subject remain visible.

Finish an explainer with audio and a thumbnail

Prepare narration, BGM, captions, and titles, then build a thumbnail that relates directly to the finished video.

Core editing and capabilities that need extra setup

Capabilities and requirements

What changes with this product

Shorten the preparation work.

Silence detection, transcription, caption candidates, quality checks, and thumbnail candidates organise the material first, so editing can begin at the places that need judgment.

Review automated decisions on a real timeline.

Run analysis before rendering, restore sections that should stay, and adjust the non-destructive timeline without changing the original footage. The same edit data can be refined and rendered again.

Keep the video and its release materials together.

Captions, BGM, narration, effects, vertical versions, thumbnails, titles, and description drafts can be prepared in one flow. Publishing connections remain subject to account setup and final review.

Requirements and support

Operating system: 64-bit Windows 10 version 1809 or later, or Windows 11. The individually supplied beta bundles its runtime and FFmpeg, so a separate Python installation is not required.
Storage: Allow about 1.5 GB for the application, plus sufficient separate space for source footage, proxies, cache files, and exports.
Input: Video and audio supported by the configured FFmpeg build. Codec support depends on the local environment and source material.
Main outputs: MP4 video, short version, SRT or ASS captions, PNG or JPEG thumbnails, HTML edit report, metadata, and timeline JSON.
AI options: Built-in AI, LM Studio or Llama, and Claude can be selected. Models, APIs, and network requirements differ by feature.
Publishing: YouTube, X, TikTok, and Instagram require authentication and permission from each service. Real-account operation is not guaranteed during Public Beta; use the review-first workflow.
Known limitations: Keyboard focus navigation has been verified, but Windows screen readers do not yet receive useful names for every custom UI control. Do not use this release where assistive-technology support is required. Final testing at 200% Windows display scaling is also pending.
Delivery: After purchase on the SAINO website, a time-limited private download URL, verified filename, SHA-256, and setup guide are emailed to the purchase address within three business days. There is no public download or in-app checkout.

Frequently asked questions

Can I correct the automatic edit?

Yes. Analyse first, review cut candidates, then adjust splits, order, captions, audio, and effects on the timeline before rendering again.

Can I edit without AI or an API key?

Yes. Core editing, FFmpeg processing, the timeline, and thumbnail design do not require cloud AI. AI analysis and external services require their own setup.

What can I do with captions and audio?

Create SRT and ASS captions, adjust their position and style, add BGM, record narration, use supported speech engines, and apply voice-aware ducking.

Will it publish automatically?

Only after publishing is configured and you explicitly approve the current content and destination. Automatic mode prepares the edit and draft, but it never bypasses the final confirmation before an external send.

Can I install the unsigned build?

Yes, but Microsoft Defender SmartScreen may identify it as an unrecognised app. Verify the filename and SHA-256 supplied by SAINO, do not disable Windows security globally, and obtain administrator approval on a managed PC.

What does Public Beta mean?

Features and quality are still being improved. Keep source backups and test long footage or unusual codecs with a short sample first.
