To keep a prerecorded video looking good after compression, start with the best source file, export a progressive MP4 with H.264, preserve the intended resolution and frame rate, and choose a bitrate suited to that resolution and frame-rate class. YouTube’s published figures are useful starting points, not guarantees: footage with fast motion or fine detail can need more data than a simple scene. These settings apply to video uploads played in a playlist; they are different from settings for a real-time YouTube Live encoder.
Choose the right workflow: playlist upload or YouTube Live
A YouTube playlist is a set of uploaded videos. Compress each video for upload, then add the finished uploads to a playlist. YouTube Live is a separate workflow: a live encoder sends a real-time feed to YouTube, which has its own ingestion requirements. Do not apply live-stream bitrate settings to a prerecorded playlist file.

For uploads, YouTube recommends MP4, H.264 video, progressive scan, variable bitrate, and the same frame rate as the recording. Its upload guidance also covers GOP structure, profile, audio, and color; the recommended settings are a compatibility baseline, not a promise that every encoder will produce identical results.

Keep the intended resolution and frame rate
Begin with the highest-quality source available. YouTube advises providing the highest available resolution and retaining the frame rate at which the content was recorded. Avoid needless downscaling or frame-rate conversion: neither creates missing detail, and conversion can introduce softness or motion artifacts. Common frame rates include 24, 25, 30, 48, 50, and 60 fps.

Keep the aspect ratio and color metadata appropriate
YouTube’s standard computer-video aspect ratio is 16:9, but its player adapts to other aspect ratios. Export the picture at its actual shape rather than adding black bars or padding; embedded bars interfere with the player’s dynamic sizing. For SDR, YouTube recommends BT.709. Unsupported color spaces may be converted, and unsupported high-bit-depth primaries without an HDR transfer function may be converted to BT.709 8-bit, so do not assume such a conversion is lossless. See YouTube’s resolution and aspect-ratio guidance and its upload encoding recommendations.
Export settings for a compressed YouTube upload
- Container and video codec: choose MP4 with H.264 video.
- Scan and rate control: use progressive scan and variable bitrate (VBR), rather than interlaced video or a needlessly fixed high bitrate.
- Resolution and frame rate: retain the intended output size and match the recorded frame rate.
- H.264 options: YouTube recommends High Profile, CABAC, two consecutive B frames, and a closed GOP with GOP length half the frame rate.
- Color: for SDR, use BT.709. Keep the export’s color signaling consistent with the source and intended output.
- Audio: YouTube lists AAC-LC, Opus, or Eclipsa Audio, with a 48 kHz sample rate.
- Bitrate: use the relevant YouTube recommendation below as a starting point. If you have a strict file-size ceiling, test a representative section before encoding the full video.
These are YouTube’s published upload recommendations; the page’s publication year is not stated. Bitrates are in Mbps. “Standard” means 24, 25, or 30 fps; “high frame rate” means 48, 50, or 60 fps. HDR and SDR have separate recommendations.

Source for every bitrate in the table: YouTube’s upload encoding recommendations; publication year not stated. These recommendations do not guarantee identical visual quality across encoders or kinds of footage. Motion, fine textures, noise, and the source’s own quality affect how well a given bitrate holds detail. If a smaller file is essential, lowering bitrate trades file size against picture quality; do not expect one number to suit every video.
Estimate file size without guessing quality
Video bitrate is only part of total file size; audio and container overhead add a little more. A practical estimate is: file size in megabytes ≈ (total bitrate in Mbps × duration in seconds) ÷ 8. For example, a 10-minute video at 8 Mbps total is about 600 MB before small overheads (8 × 600 ÷ 8). If your export tool reports video bitrate separately, add audio bitrate for a closer estimate. To hit a size limit, test a short section with representative motion and detail, inspect it at full size, and adjust bitrate in small steps rather than reducing resolution or frame rate by default.

Upload, build the playlist, and verify playback
- Upload the exported MP4 to YouTube. If viewers need the higher-resolution options as soon as the video is public, upload it as unlisted first.
- Wait for processing, then check the video’s quality menu at the intended resolution. YouTube initially processes new uploads in low quality; 1080p and 4K options can take several hours to appear.
- After the desired quality options are available, change visibility as needed and add the upload to the playlist.
- Check playback on a device or browser that supports the target quality. Some device or browser limitations can prevent certain quality options from appearing.
YouTube describes the low-quality-first processing behavior and suggests unlisted upload followed by publication after higher qualities are available in its video processing guidance.

- Only low resolutions appear shortly after upload: the video may still be processing. Wait for higher-quality versions to finish before judging the export.
- The image is soft at every quality: check whether the export was needlessly downscaled, whether the source itself is soft, and whether bitrate is appropriate for the resolution and motion.
- Fast movement breaks into blocks: the chosen bitrate may be too low for that scene. Test a higher bitrate on representative motion before re-encoding the full video.
- Colors look different: verify that the SDR export uses BT.709 and that color metadata matches the intended output. A conversion from unsupported color metadata may change the result.
- The shape looks wrong or has bars: check the output dimensions and aspect ratio; avoid baking in padding or black bars.
- Quality options are missing on one device: compare playback on a supported browser or device after processing; availability can vary with device capabilities.

Keep compression separate from copyright and playlist eligibility
Good export settings affect picture and sound quality; they do not grant permission to upload or stream the material. Make sure you have the rights or appropriate permission for every recording, track, and visual in the playlist, and review YouTube’s applicable copyright and monetization rules. Compression cannot make unlicensed material permissible or guarantee that a channel qualifies for monetization.
Or let it run in the cloud
If your playlist is meant to run continuously as a YouTube Live stream, that is different from simply playing a playlist of uploads. YouTube Live has real-time ingestion settings—including constant bitrate for supported configurations and a recommended two-second keyframe interval, not over four seconds—rather than the upload bitrate table above.
