Watermark Studio

Watermark Studio — batch watermarking and local stamp removal for photos and videos on Android.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
ADD WATERMARK
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Pick multiple photos or videos with the system photo picker
• Text watermarks: content, font (sans / serif / mono / bold), color, size, opacity
• Image watermarks: add your logo or PNG overlay
• Multi-layer editing: add, switch, and remove layers
• Drag watermarks on the preview to position them (matches export placement)
• Batch export to your gallery with progress for each item
• Partial success supported if some files fail in a batch

Video export:
• Free: up to 720p
• Pro: up to 1080p
• Adjustable export length presets (Pro unlocks longer targets including up to 5 minutes)

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
REMOVE STAMP / WATERMARK (LOCAL PROCESSING)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Remove unwanted stamps, logos, or text in a selected region. Processing runs on your device using OpenCV-based inpainting and temporal recovery — not a cloud AI service. Results depend on background complexity and motion.

• Photos and videos supported (video may be unavailable on emulators or low-memory devices)
• Drag the green box on the preview to target the stamp; resize the region with a slider
• Live preview on the current frame before export
• Video exports try to keep the original audio track when muxing succeeds

Quality tiers:
• Free (Standard): TELEA inpaint on images; optical-flow assisted recovery on video; up to 15 seconds per clip at up to 60 fps (within a 900-frame budget); up to 720p export
• Pro (Advanced): NS inpaint + seamless blending on images; enhanced optical-flow video recovery; up to 5 minutes per clip at source frame rate (up to 60 fps, no fps downgrade for length); up to 1080p export; higher image processing resolution

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
FREE PLAN
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• 3 successful exports per day (shared between watermarking and stamp removal)
• Standard removal quality
• 15-second video removal cap, 720p video export ceiling
• Banner ads in the editor and optional interstitial after a successful export
