Video Bitrates: The Technical Guide for YouTube, TikTok, and Instagram

When you upload a video, the platform always recompresses it. If your initial bitrate is too low or poorly configured, the result will be pixelated. **YouTube 4K**: Aim for a bitrate of 45 to 60 Mbps in H.264. For 1080p, 8 to 12 Mbps is enough. **TikTok & Reels**: These platforms are optimized for mobile. Use a constant bitrate (CBR) of 5 to 8 Mbps to avoid micro-stutters when loading on unstable 4G/5G connections. **AAC Audio**: Don't neglect the sound. The standard for social networks is AAC at 192 or 256 kbps. PulsConv automatically integrates these presets into its 'Social Media Optimization' tool to guarantee the best result after upload.
