TLS Viewer turns your iPhone or iPad into a wireless video-village monitor for NDI® sources on your local network. Made by a working video-assist operator for film and commercial sets, it does one thing well: show the feed, clearly, with the tools you reach for between takes. WHAT IT DOES • Finds NDI® senders on the same Wi-Fi automatically. No IP addresses to type. • Single-source monitor with pinch-to-zoom and pan for focus checks. • Multi-view grid to keep several sources on one screen. • Histogram and false colour for exposure calls. • Live link stats: frame rate, latency, dropped frames, so you know when the network is the problem. • Bandwidth switch: full quality on a clean network, proxy mode when the Wi-Fi is crowded. • Reconnects on its own when the network changes. The last frame stays on screen with a clear status chip. • Keeps the screen awake while you are monitoring. Tap once to hide all controls. WORKS WITH Any NDI® sender on your network: switchers, capture apps, cameras, and video-assist systems that publish NDI®. A built-in demo source lets you explore every tool without a sender. PRIVACY TLS Viewer collects nothing. No account, no analytics, no tracking. Video stays on your local network. NDI® is a registered trademark of Vizrt NDI AB. TLS Viewer is an independent product of Tech Lab Studio and is not affiliated with or endorsed by Vizrt NDI AB.

Capture Every Perspective in One Take Stop choosing between TikTok and YouTube. Dual Recorder: Both Aspect Videos is the ultimate tool for content creators who need to be everywhere at once. Leveraging advanced multi-camera processing, this app allows you to record vertical and horizontal video simultaneously, saving you hours of editing and ensuring you never miss the perfect shot in either format. Whether you are capturing a cinematic landscape for your vlog or a high-energy portrait clip for your social feed, Dual Recorder: Both Aspect Videos handles the heavy lifting. One session, two separate files, zero compromise. Key Features Dual Format Recording: Record in 9:16 portrait and 16:9 landscape at the exact same time. The app generates two distinct high-quality video files from a single recording session. Dual Lens Integration: Utilize different lenses on your device to capture the widest field of view for landscape while maintaining a focused portrait frame. Single Lens Mode: Even in single lens mode, the app uses intelligent cropping and sensor utilization to provide both formats instantly. Pro-Grade Controls: Take full command of your output. Adjust resolution (up to 4K), frame rates (24, 30, or 60 fps), and file formats (MOV or MP4) to match your workflow. Instant Export: No more cropping or stretching in post-production. Your videos are saved to your library ready for immediate upload to any platform. Visual Guidance: Integrated on-screen overlays show you exactly what is being captured in both frames, so you can compose your shots perfectly for every destination. Why Dual Recorder: Both Aspect Videos? Modern social media demands multiple formats. Traditionally, this meant recording twice or losing significant quality by cropping a horizontal video into a vertical one. Dual Recorder: Both Aspect Videos solves this by maximizing your iPhone sensor's potential, giving you professional results for Reels, Shorts, and traditional video platforms simultaneously. Note: Some features, including 4K recording, high frame rate options, and advanced dual-lens configurations, may require a paid subscription.
