VidNo produces professional-grade video output that is uploaded directly to YouTube via API — no manual upload step, no copying metadata into YouTube Studio. The rendered files are optimized for YouTube's encoding pipeline so they retain maximum quality after re-compression.
The default output resolution is 1920x1080 (1080p) at 30 frames per second. This matches the resolution of most developer screen recordings and produces crisp, readable code on screen. Text clarity is a priority — VidNo's rendering pipeline is tuned to ensure that code, terminal output, and UI elements remain sharp and legible in the final output, even after YouTube's compression.
On the Pro plan, you unlock 4K output (3840x2160) and 60fps rendering. 4K is particularly valuable if your screen recordings are captured at 4K or if you use high-DPI displays. The extra resolution ensures that dense code with small font sizes remains readable even on smaller playback screens. 60fps is useful for recordings that involve smooth scrolling, animations, or browser interactions where 30fps can look stuttery.
The video codec is H.264 (AVC) with a high bitrate profile. VidNo defaults to a bitrate of 12 Mbps for 1080p and 40 Mbps for 4K, which is well above YouTube's recommended upload bitrate. This means your video retains maximum quality through YouTube's re-encoding process. The audio codec is AAC at 320kbps, which preserves the full fidelity of both the AI voice and any system audio captured during recording.
Container format is MP4 for maximum compatibility. Every platform accepts MP4 without conversion.
For the short-form outputs (highlight reel and YouTube Short), VidNo automatically renders in 9:16 vertical format at 1080x1920, optimized for YouTube Shorts and other vertical video platforms. It intelligently crops the most relevant portion of your screen rather than just letterboxing the horizontal recording.
File sizes for the full tutorial output typically range from 500MB to 2GB depending on length and resolution. The quick recap, highlight reel, and YouTube Short are proportionally smaller. All output files land in ~/vidno/output/ organized by date and session name, and are uploaded to YouTube automatically as part of the pipeline.
