--- title: "Creator Tools for Audio, Video and Sharing" description: "Trim audio and video, prepare captions, record clips and create profile QR codes. Browser tools for creators with local media processing." url: https://candoya.com/tools/social/ locale: en type: tool-category --- # Social and creator tools Creator work often involves a small change between recording something and sharing it. Trim an audio clip, remove sound from a video, extract a frame for a thumbnail or adjust a subtitle file. Profile QR Code turns a public profile link into a scannable image. These tools focus on individual steps, so you can choose the task you need without setting up a full editing project. Media support depends on both the file container and the codec inside it. Two files with an MP4 extension can behave differently in the same browser. Re-encoding can change quality and take time, especially for long recordings or high-resolution footage. Keep the original, try a short clip first and play the exported file before publishing. Microphone, camera and screen recording also require the permissions appropriate to that task. Some tools download a speech or image model before processing locally. The initial download can be substantial, and a phone may have less memory available than a desktop. Transcripts, captions, summaries and other model outputs need review: names, numbers, background noise and unfamiliar languages can lead to mistakes. A generated caption is a useful draft, but checking it against the original recording is part of preparing it for an audience. ## Social & Creator tools - [Depth Estimation](https://candoya.com/tools/depth-estimation/): Estimate relative scene depth from a photo with on-device AI.
