RepostLock: Video Watermark

Put your name on your videos. RepostLock adds text or a PNG logo to your videos. Choose a simple watermark or a moving, repeated pattern to help deter unauthorized reposting. • Add your name or a PNG logo • Normal mode: place a watermark where you want it • Strong mode: moving, repeated text or logos with animated wave distortion • Adjust size, opacity, color and position with a preview • Process video on your device, save to Photos and share • English and Korean interfaces with a short first-launch guide Both modes are available for free. Free exports display an ad and include the RepostLock name at the bottom center of the saved video. The free editor also displays a banner ad. An internet connection and an available ad are required. A one-time Lifetime purchase removes ads and the RepostLock label. It is not a subscription. Your own text or logo remains on the video. Restore purchases from Settings. Your original video stays unchanged. Export is SDR H.264 MP4, up to 1920 pixels on the long edge and 1080 on the short edge. HDR video is not supported. Watermarks are a deterrent. RepostLock does not guarantee prevention of copying or AI removal, or visible damage after removal. Use videos you own or have permission to edit.
