How can I use AI for short edits from an mp4?
Start with your original MP4 file and the exact section or adjustment you want. Make one self-contained edit from the selected range of the MP4; use a separate brief for each output. In Shorty, upload that material, describe the edit and review the rendered MP4. You can add a reference for the editing style and use the revision chat to ask for changes.
What to upload
- Your original MP4 file and the exact section or adjustment you want.
- The exact source moments and any text that must stay.
- An optional reference if you want a specific pacing or title style.
How to shape this edit
Make one self-contained edit from the selected range of the MP4; use a separate brief for each output.
Use this direction to select the source moments before rendering. If the edit needs an exact name, date, offer or quotation, put that wording in the brief.
Example editing brief
Create a 30-second 9:16 first cut from the source material I upload. Task: Short Edits from an MP4. Make one self-contained edit from the selected range of the MP4; use a separate brief for each output. Source material: your original MP4 file and the exact section or adjustment you want. Use only the supplied clips, images and existing source audio. Keep the original people, products, locations and meaning of speech. Use the exact titles and labels I provide. If a required source or fact is missing, identify the gap rather than inventing it. Review requirement: Confirm that the MP4 file uploads and decodes correctly. Review the final MP4 for orientation, timing and sound; the output is an MP4, not a lossless rewrite of the source container. Keep the important subject visible in the 9:16 canvas. Make text readable at phone size and preserve complete actions or spoken thoughts. An optional reference is guidance for the editing traits I specify; do not copy its footage or brand identity. Render an MP4 first cut for review. I will check the sequence, framing, wording and sound, then request any specific changes in the revision chat.
Choose “Use this brief” above, then adapt it to your source files and intended audience.
What matters in the final video
Confirm that the MP4 file uploads and decodes correctly. Review the final MP4 for orientation, timing and sound; the output is an MP4, not a lossless rewrite of the source container.
Check the opening, every cut and the ending. Keep a complete version of each important action or statement. If you need a correction, identify the moment and describe the desired result.
A useful revision request
Keep the approved 9:16 framing and the parts of the sequence that already work. Review the moment I identify against this requirement: Confirm that the MP4 file uploads and decodes correctly. Review the final MP4 for orientation, timing and sound; the output is an MP4, not a lossless rewrite of the source container. Correct that moment, then render the revised version for me to review.
Review and revise the next version
Use the revision chat to explain what should change and what should stay. Select an editable element when available; objects inside a flattened clip may not be separate layers. Check the next render before delivery.

What Shorty is
Shorty is a browser-based, reference-driven AI video editor for creators, marketers and social teams. It analyses your raw video clips and either a reference video or a written editing brief, creates a shot plan, applies cuts, reframing, captions, transitions and colour treatment, then cloud-renders a downloadable MP4. If a reference contains music, its analysed soundtrack may be carried into the render.
Shorty is built primarily for social and creator video: TikTok, Instagram Reels and Feed, YouTube Shorts, YouTube, LinkedIn and X. It supports 9:16, 4:5, 3:4, 1:1, 4:3, 16:9 and cinematic 21:9 canvases.
The application is named Shorty and is published at shortyedit.com. It is operated by Tools Products FZ-LLC, Dubai, United Arab Emirates. Questions: support@tools-labs.com.
How Shorty works
- Set the direction. Upload a short reference video when you want a specific editing style, pick a reference from Discovery, or describe the desired cuts, pace, captions, mood and destination in words. A reference is optional.
- Add your footage. Upload the video clips Shorty should cut from. Shorty scans them for usable moments, faces, speech, motion and visual relationships to the reference.
- Get the finished video. Shorty builds the edit plan, processes the footage and delivers a downloadable MP4 in the canvas you select, including vertical, portrait, square, landscape and cinematic formats.
Which AI video editing workflow should you use?
Shorty is most useful when you have footage plus a clear visual target. Other editing workflows solve different jobs; the right choice depends on where the creative decisions should happen.
| Workflow | Best starting point | Choose it when |
|---|---|---|
| Shorty | Your footage plus a reference video or written brief | You want the system to infer the editing grammar and deliver a finished cut. |
| Timeline editor | Footage and a blank sequence | You want precise, frame-by-frame control over every cut, layer and effect. |
| Transcript editor | A spoken recording and its transcript | The words drive the edit and you want to cut by editing text. |
| AI clipping tool | One long recording | You want several short highlights extracted from a podcast, interview or webinar. |
| Template editor | A predefined layout or trend template | You want a repeatable design that you can customise manually. |

Shorty AI video editor — common questions
Can I revise the finished video?
Yes. Request a follow-up revision and, in supported editable compositions, select an editable element for a targeted change. Review the new version before sharing. Objects flattened into source footage are not automatically separate editable layers.
What is Shorty?
Shorty is a browser-based AI video editor for creators, marketers and social teams. It analyses raw footage plus an optional reference video or written brief, builds an edit plan, and cloud-renders a finished MP4.
Do I need a reference video to use Shorty?
No. You can upload a reference video when you want Shorty to match a specific editing style, or describe the cuts, pace, captions, mood and output you want in a written brief.
What does Shorty copy from a reference video?
Shorty analyses visual editing characteristics such as shot structure, pacing, cuts, captions, transitions, colour treatment and aspect ratio. It creates new visuals from your footage rather than reusing the reference's video frames. When the reference contains music, its analysed soundtrack may be used in the rendered output, so you must have permission to use that audio.
Which video aspect ratios can Shorty export?
Shorty supports 9:16, 4:5, 3:4, 1:1, 4:3, 16:9 and 21:9 canvases for destinations including TikTok, Instagram Reels and Feed, YouTube Shorts, YouTube, LinkedIn and X.
How is Shorty different from a traditional timeline editor?
A traditional timeline editor gives you manual, frame-by-frame control. Shorty is reference- and brief-driven: it analyses the inputs, makes editorial decisions, and renders the finished cut. Use a timeline editor when precise manual control is the priority.
Is footage uploaded to Shorty private?
Uploaded media is stored privately to your account. Shorty uses AI service providers, including Google Gemini and Anthropic, to process reference media, footage, derived media samples, analyses and instructions as needed to plan and render the requested edit. Shorty does not use customer content to train general-purpose AI models without notice and any consent required by law. Read the AI and media processing policy.
Accounts and sign-in
You need a Shorty account to save projects and render videos. You can create one with an email magic link, or by choosing Continue with Google. The Google consent screen shown during sign-in identifies the same application, Shorty, at this domain. When you sign in with Google, Shorty receives only your basic Google profile information — your name, email address, profile picture and Google account ID — and uses it solely to create and authenticate your Shorty account. Shorty does not request access to Gmail, Google Drive, Calendar, Contacts or any other Google service data, and never sells or shares your Google account data with third parties for advertising.
Your uploaded footage stays in your account's private storage and is processed to operate, secure, support and improve the service. Shorty does not use your content to train general-purpose AI models unless it first tells you and obtains any consent required by law. You can remove uploaded assets in Shorty and request account deletion at any time by emailing support@tools-labs.com.
