Muvize v1.5 — Creator Toolkit & Mobile Polish

Muvize v1.5 — Creator Toolkit & Mobile Polish 🎨

This release focuses on helping creators get more out of their workflow — from discovering AI music platforms to managing their media library more efficiently — while making the entire app feel great on mobile.

What's New

Creator Guides Hub

A new /guides section with step-by-step workflows for 9 AI music platforms:

Suno, Udio, Mureka, Somio, Mubert, BandLab, Beatoven, Soundverse, and Tad AI
Each guide covers platform strengths, generation tips, and how to bring tracks into Muvize
Breadcrumb navigation and consistent typography across all guide pages

Cover Art Extraction

Upload an audio file and Muvize now automatically extracts embedded cover art:

ID3v2 APIC frame parsing — Supports ID3v2 versions 2, 3, and 4 with proper frame size decoding
Image type detection — Identifies JPEG, PNG, and GIF from file signatures
Persistent storage — Cover art saved to IndexedDB alongside the audio file
Thumbnails everywhere — Cover art appears in the library grid, list view, and studio media modal
Extraction runs in the background so it never blocks the UI

Media Downloads

You can now download any file from your library or timeline:

Library — Right-click or use the menu on any file → Download
Timeline — Right-click a clip with a source file → Download
Creates a temporary blob URL and triggers a native save dialog

Bulk Job Deletion

Long-press (or shift-click) jobs in Depth Animation or Stem Splitter to enter multi-select mode:

Select/deselect individual jobs or use "Select All"
Bulk delete with a single confirmation dialog
Visual feedback with a violet highlight ring on selected items

Save to Library (Depth Animation)

Depth Animation results can now be saved directly to your media library with one click — no need to re-download and re-import.

Credit Cost Update

Spotify Lyrics now costs 1 credit (previously free) to align with other URL-import features. Insufficient-credits dialogs now appear before starting a job, not after.

Chroma Key Stability

The WebGL green screen renderer received several fixes for real-world video playback:

Premultiplied alpha blending corrected (blend function uses ONE instead of SRC_ALPHA)
GPU context loss/restore handlers recover gracefully from video interruptions
Canvas resize threshold (2px) prevents GPU reallocation on sub-pixel changes
Pixel storage hints (UNPACK_PREMULTIPLY_ALPHA_WEBGL, UNPACK_FLIP_Y_WEBGL) for correct texture uploads
Unnecessary WebGL features (antialias, depth, stencil) disabled to reduce memory overhead
Draw coordinates rounded to integers to avoid floating-point precision issues

Indonesian Pricing — 50% Discount

Regional discount for Indonesian users increased from 30% to 50%. All IDR credit pack prices recalculated accordingly, making Muvize more accessible in the Indonesian market.

Mobile & Responsive Overhaul

Every client-facing page has been tuned for smaller screens:

Depth Animation, Karaoke Maker, Stem Splitter, and Library layouts optimized for mobile
Sticky action buttons and better text truncation on tool pages
Project list redesigned with touch-friendly interactions
Pricing, Support, and Updates pages reflowed for narrow viewports
CountUp animation refactored to always animate (no more intersection-observer gating on mobile)
Landing page compositor thrashing on Android Chrome resolved

Refreshed Branding

New app icon set across iOS, Android, and Windows (smaller file sizes, sharper rendering)
Updated logo assets (logo-symbol-text.svg, logo-text.svg, PNG variants added)
Favicon refreshed to match new icon style

SEO & Discoverability

llms.txt added for AI model discovery and indexing
Enhanced metadata across all public pages
Guide routes added to sitemap and robots configuration
Startup Fame badge displayed in the hero section alongside Product Hunt

Playground Refactor

The public playground has been completely rebuilt into a dynamic editor with full project persistence:

Two-step flow — Upload or import audio on /playground, then edit in /playground/[id] with all changes saved automatically
Audio import — Upload local files (free) or paste YouTube/Spotify links (1 credit) with real-time progress
Project persistence — Full state saved to IndexedDB and synced to Supabase, including media files, clips, and visualizer config
Audio visualization — 8 preset visualizer presets with real-time spectrum rendering and customizable effects (stars, particles, glow)
Auto-captions — One-click transcription with synced word-level timing, positioned at the bottom by default
Caption controls — Toggle visibility, change position (top/center/bottom), pick from 5 style presets, and choose animation type
Audio trimming — Visual waveform editor with draggable handles, apply/reset support, and captions automatically re-timed to match
Viewport presets — Switch between 9:16 (portrait), 16:9 (landscape), and 1:1 (square) formats
Playback controls — Spotify-style transport bar with seek, restart, play/pause, and mute toggle
Background & logo — Upload custom background images/videos with opacity control, or add a logo to the visualizer
Export — Full video encoding and download via the existing export pipeline
Project management — Rename, delete, or bulk-delete recent projects from the landing page
Credit awareness — Available credits shown in the header, insufficient-credits dialog before costly actions
Mobile-first layout — Proportional split (header / canvas / transport / scrollable properties) optimized for phone screens
Authentication gate — Unauthenticated users redirected to login with a return URL back to the playground

History Panel Component

A reusable HistoryPanel component now powers the job list in Depth Animation, Karaoke Maker, and Stem Splitter — eliminating hundreds of lines of duplicate code across tool pages.
