About ULTRA MOTION + UMV ENGINE! v6.6.6

Ultra Motion is a full rebuild of Alight Motion, made by an editor who got tired of waiting. Everything premium is unlocked, you can import and export project packages above 5 MB, 497 extra effects are built in, the whole app uses one consistent dark mode, and the bugs the developers ignored for years are finally fixed. Free since 2023, and it stays that way. Here is everything that makes it the only one of its kind:

What's new in this build

• Demo Mode removed and force disabled.
• Fixed some small details of Full dark mode.
• Import Project Package in-app — paste a link or pick a QR code; no more enabling links in settings or opening a browser.
• UMV Engine — patch or re-encode your video, save it anywhere, post it on TikTok and get an uncompressed high-quality upload.
• Audio Converter — some audio drifts when you seek; convert it here (CBR MP3) and it stays perfectly in sync.
• Live timeline switch — added a toggle for a live timeline feature that let's you scrub and pinch the timeline while playing without any interruptions.
• New audio meter look — enhanced iOS-style live audio bar.
• XML export with save-as — pick the folder and rename the file before saving.
• XML export inside the editor — an XML row was added to the Export & Share page in the edit screen.
• Adaptive bookmarks — bookmarks keep lighting up after you switch the project fps.
• Fixed effect edge smearing — 3D and other effects no longer smear at the edge when a layer is scaled past the frame.
• Fixed 3D effects scaling the layer down — Cube, Sphere and the other 3D effects now fit the layer size when applied.
• Fixed export size not applying — changing the project ratio or resolution now applies to the export.
• Fixed the -90 rotation on exported portrait videos — portrait exports are saved upright, no more sideways file.
• Fixed the pen tool crash — no more crash when dragging on the pen tool panel.
• Fixed the missing media crash — a deleted media file no longer kills the app.

Special features

Everything on this list is real and permanent, in every build. Most of it exists in no other mod.

The highlights

• Full premium, project packages above 5 MB. Unlocks importing and exporting project packages above 5 MB. A feature regular mods cannot do.
• 497 new extra effects. A pack of 497 custom extra effects collected from popular mods.
• Ultra frame rates up to 1920 fps. Adds higher frame rate options: 120, 240, 480, 960, and 1920 fps.
• 4K video import and HEVC export. Import 4K videos, and export with the HEVC codec even on devices that normally do not support it.

Live timeline

• Smooth live timeline scrolling. Scroll through your timeline while playback keeps running, continuously and uninterrupted.
• Smooth live timeline pinch zoom. Pinch to stretch or shrink your timeline while playback keeps running, without a single pause.

Effects, organized

• Organized effect categories. 20 new categories built separately for the extra effects, so everything stays easy to find.
• Quick effects search. A very fast search engine with zero lag while you type in the effects search bar.

Import and export tools

• Auto retry for failed project imports. Project package links often fail because of a server request limit. Ultra Motion now retries automatically, so you never have to restart the import yourself.
• XML multi import. Select multiple .xml or .zip files at once.
• XML export straight to Documents. Exported XML presets go directly to your Documents folder.
• XML named after your project. Exported XML presets automatically get your project's name.
• Project package QR code in the Ultra Motion theme. Exporting a project package gives you a customized QR code with Ultra Motion branding and the same dark theme.

Find anything

• Project list search bar. Search your projects, templates, elements, and cloud projects with a fast, optimized search engine.
• Audio browser search bar. Find your songs faster with a search bar right in the audio browser.

Look and feel

• Full dark mode, one consistent theme. Now with a new look. The dark theme covers every part of the app, from the status bar to the last settings page.
• iOS style audio meter. The live audio meter now shows two bars, matching the look of the iOS version of Alight Motion.

Private and fast

• Full offline support, instant open. Opens instantly, with or without internet.
• No onboarding or privacy screens. The first launch goes straight to the home screen. The privacy and agreement screens are completely removed.
• All trackers removed. Every analytics library, ad library, and tracker is completely removed.

Runs on everything

• Full support for Huawei, AOSP, emulators, and non-GMS devices. Devices that do not meet the Google Play Services requirements are fully supported.
• A Clone version that actually works. The only mod with a fully working Clone version that can still communicate with the server.
• Every language. Supports every language the original app ships.
• ARMv7a and ARM64. Runs on both 32-bit (ARMv7a) and 64-bit (ARM64) devices.
• Android 7.0 and up. Supports Android 7 all the way up to Android 16.

Original app bugs, fixed

These bugs have been in the official app for years. The devs never fixed them, so every mod out there still has them. Ultra Motion stopped waiting and fixed them all. No other mod can, the work is just too complex.

Audio, finally fixed

• Audio drifting out of sync. Seeking through the timeline used to play audio from the wrong spot after you paused. Audio is now perfectly synced in real time and plays exactly where you last paused.
• Audio waveform accuracy. The sound waveform is now 100% accurate, so you can mark every beat exactly where it really lands.
• Audio volume keyframes. Fading the volume in or out with keyframes now works accurately, the way it always should have.
• Audio volume panel. Opening the volume panel, going back, and reopening it used to break it. It now opens and closes as many times as you want.

Editing, fixed

• All group layer bugs. Persistent navigation, header, and editing bugs inside group layers, and many more group layer annoyances, all fixed.
• Effect smearing and glitches. The smearing and glitch artifacts that 3D effects, distortion effects, and some other effects used to leave on screen are gone. Effects now render cleanly.
• Numeric keypad. Typing a value no longer opens your system keyboard on top of the app's own keypad.
• Text box visibility. The bottom part of the text box is no longer covered by your keyboard while editing text. The whole text box stays visible.
• Edit page home screen bug. Pressing the home button while inside the edit page no longer kicks you out of your project.

Exporting, fixed

• Project settings that stick on export. Changing the project ratio or resolution in the project settings now applies consistently during export.
• Export and share page navigation. You can move between pages on the export page without everything closing when you press back.

Templates and media, fixed

• Template media replacement. Replacing media in a preset or template now saves permanently, as it should.
• Media info that shows real values. Media info now shows the real dimensions and format instead of null and blank fields.

System, fixed

• HyperOS font import. Font importing works on all the latest HyperOS versions.
• Stuck at the loading screen. Being offline or on slow internet no longer leaves you stuck at the loading screen.

Original version or Clone version

Both versions have the same features. Only the package name is different.

Clone version

The Clone version does not replace Alight Motion. The two apps do not conflict.

Original version

The Original version replaces Alight Motion. Uninstall Alight Motion first, otherwise the installation fails.

Try the Clone version first. You can keep the Clone version as long as you want. To compare Ultra Motion with Alight Motion, you need the Clone version.

Save a copy of your projects before you uninstall any app.
