YouTube accepts a wide range of files, but its upload guide publishes bitrate recommendations that are useful starting points. Exporting too low can show obvious compression artifacts. Exporting far above a meaningful source quality may waste disk space and upload time without recovering detail lost earlier in production. A quality-controlled workflow keeps resolution, frame rate, codec and bitrate choices consistent with the actual source.
1. Start with resolution and frame rate
For standard dynamic range (SDR) video, YouTube lists approximately 8 Mbps for 1080p at 24–30 frames per second and 12 Mbps for 1080p at 48–60 fps. For 1440p, the corresponding recommendations are 16 and 24 Mbps. At 4K (2160p), the normal-framerate reference is 35–45 Mbps and the high-framerate reference is 53–68 Mbps. These are recommendations, not hard minimums or guarantees of a particular result. Official YouTube encoding reference ↗.
2. Keep the original cadence
Official guidance recommends uploading at the same frame rate used during recording. If the footage was captured at 30 fps, converting it to 60 fps will not create genuine extra camera detail. For interlaced footage, the upload should be progressive. If you are working with animation or compositing, render with the frame rate your timeline actually used and check whether motion judder is introduced by mixed assets.
3. Think about codec and audio
For widely compatible uploads, MP4 with H.264 video and AAC-LC audio is a sensible baseline. YouTube's official recommendations also describe Opus and other supported audio codecs and additional technical preferences. Stereo upload guidance lists 384 kbps as a recommended audio bitrate. Choose audio settings based on the source and export capability, then play the final file from start to finish or sample every chapter and transition.
4. Translate bitrate into file size
A 120-second 1080p30 video at 8 Mbps video plus 384 kbps audio has an approximate size of 126 MB before additional container overhead (8.384 megabits × 120 ÷ 8 ≈ 125.76 megabytes). A variable bitrate encoder can produce a different real size depending on image complexity and its quality-control settings. Our upload size estimator makes this math transparent.
5. Check the export rather than trusting the preset
- Confirm the true pixel size with your editing app or media inspector.
- Check whether you exported SDR or HDR and apply the appropriate reference table.
- Inspect frame rate and audio channels.
- Decode or play the file and watch for missing frames, glitches, blank sections and clipped audio.
- Keep a copy of the final approved MP4 so a network interruption does not trigger a unnecessary re-render.
