Quick Merge: Video Joiner APP
WHY CREATORS LIKE IT
• Simple flow: pick → reorder → merge → share
• Clean results: one MP4, H.264 video + AAC audio at 30 FPS for broad compatibility
• Smart engine: tries “fast merge” first; safely falls back to re-encode when sources differ
• Precise timing: normalizes streams and adds silent audio to silent clips to avoid drift
• Modern UI: Material design with auto light/dark theme
• Built-in Gallery: play, share, or delete merged videos without leaving the app
WHAT YOU CAN DO
• Combine multiple videos into a single MP4
• Drag and drop to arrange clip order
• Watch progress in real time with an option to cancel
• Open results in the in-app Gallery or your device’s Movies folder
• Share to social, messaging, cloud, or any app that accepts video
HOW IT WORKS (UNDER THE HOOD)
• Fast path: When input formats already match (codec, frame rate, size), the app performs a near-instant concatenation to preserve quality and save time
• Safe path: If inputs differ, the app re-encodes to a consistent baseline—H.264 (yuv420p) + AAC at 30 FPS—so the final video plays reliably on most devices and platforms
• Audio handling: If a clip lacks audio, a silent track is generated to keep audio/video timelines aligned during concatenation
DESIGNED FOR:
• Short-form creators who batch clips into one post
• Students making quick class submissions
• Families combining vacation highlights
• Anyone who wants a dependable “just merge it” tool without extra steps
TIPS FOR BEST RESULTS
• Keep enough free storage for temporary files—merging needs working space
• Very large or highly mixed clips (different sizes/codecs) may use the safer re-encode path, which takes longer but ensures a clean result
• Keep the screen on during long merges for smoother performance
• For the fastest merges, capture or export source clips with the same resolution, frame rate, and codec
PRIVACY & DATA
• No sign-in or account creation
• Videos are processed on your device; nothing is uploaded to our servers
• The app displays Google ads; ad SDKs may collect device signals to deliver and measure ads. See the in-app Privacy Policy for details
ACCESSIBILITY & USABILITY
• Large buttons and readable labels
• Clear progress with percentage and elapsed/total time
• Cancel action to stop a merge safely
TROUBLESHOOTING
• Merge failed? Try again—if a quick concat isn’t possible, the app will switch to the safe re-encode path
• Can’t find the output? Open the in-app Gallery or check your Movies folder
• Out of storage? Free space and retry
• Audio out of sync in source files? Re-encode mode will normalize timing in the final output
