YouTube’s current upload guidance recommends MP4 with H.264; separately, it says viewers need a browser or device that supports VP9 to watch new 4K uploads in 4K. Those are different parts of the process: your upload codec is not necessarily the codec YouTube prepares for playback.
What VP9 is—and where it fits
VP9 is a video compression codec developed by the WebM Project. A codec encodes and decodes video; it is not a file container or a preset you must choose in your editor. A file’s container (such as MP4) can hold video encoded with a codec such as H.264.
For a YouTube creator, distinguish three stages:
- Export and upload: You encode a file, then upload it. YouTube’s general recommendations specify MP4 as the container and H.264 as the video codec.
- Processing: YouTube processes the upload into playback versions. The cited upload guidance does not promise that a particular upload codec will produce a particular playback codec.
- Viewing: The viewer’s browser or device must support the relevant format to play a version. YouTube says support for VP9 is needed to view new 4K uploads in 4K.
That viewer requirement is not an instruction to encode your upload as VP9.
Do you need to upload in VP9?
For an ordinary YouTube upload, follow YouTube’s published upload recommendations rather than switching to VP9 solely to try to influence playback. YouTube recommends MP4/H.264, matching the source frame rate, and using a bitrate appropriate to resolution and frame rate. Its guidance says, “The bitrates below are recommendations for uploads.” They are upload recommendations—not VP9 playback bitrates. YouTube’s recommended upload encoding settings

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.

For example, YouTube’s SDR upload table lists 35–45 Mbps for 2160p at standard frame rates and 53–68 Mbps at high frame rates. These figures apply to uploads in the listed SDR category; they are not a requirement to use VP9 and should not be mistaken for a universal bitrate target for every video.
Consider creating a VP9 encode when you have a concrete delivery need—for example, a distribution or adaptive-streaming workflow that specifically calls for VP9 files. Google’s file-based VP9 guidance offers encoding settings and examples for that kind of job. It is not a YouTube upload mandate, and its VOD guidance is not a live-stream encoding recipe.

What VP9 can—and cannot—promise
Google says VP9 can reduce video bit rates “by as much as 50% compared with other known codecs.” That is a broad maximum claim, not a guaranteed saving for every video, encoder, setting, or comparison. A result depends on the source, quality target, encoding choices, and the codec used as the comparison.
Google describes VP9 as supporting web and mobile video, including ultra-HD, 10- and 12-bit encoding, and HDR. Those capabilities do not mean every player supports every VP9 profile or that YouTube will serve VP9 to every viewer. The current YouTube upload guidance establishes the viewer compatibility point for new 4K uploads, but does not document a creator control or guarantee for selecting the playback codec.

There is no current independent benchmark in the cited material that establishes a universal VP9-versus-H.264 quality or file-size advantage across creator content. Avoid treating a codec name or one headline percentage as a quality guarantee.
How to choose an encoding workflow
Choose based on the actual job, not a blanket claim that one codec is always better. YouTube’s upload guidance is the simple default for a standard upload; a direct VP9 encode is an optional workflow for a specific delivery requirement.

| Decision factor | What to consider |
|---|---|
| Upload compatibility and simplicity | For a standard YouTube upload, the published recommendation is MP4 with H.264. |
| Content and quality target | Motion, fine detail, resolution, and frame rate affect the encode. Compare the output for your own material at a chosen quality target rather than assuming a fixed gain. |
| Encoding time and hardware | Encoding speed matters, especially for large files or repeated exports. A quality-focused workflow can take longer; balance that cost against the delivery need. |
| Playback devices | Consider whether your intended viewers’ browsers and devices support the codec and profile you plan to distribute. YouTube specifically identifies VP9 support for viewing new 4K uploads in 4K. |
| One file or adaptive delivery | A single-resolution file is different from an adaptive ladder with multiple renditions. In adaptive streaming, a player can select a rendition as available bandwidth changes. |
| Live or on-demand | Google’s VP9 settings discussed here are for file-based VOD encoding. They do not specify a live-encoding recipe. |
VP9 VOD settings: a starting point, not a YouTube rule
Google’s VP9 guidance recommends constrained-quality (CQ) encoding with bitrate bounds for VOD. Its examples include CQ 31 at 1080p and CQ 24 at 1440p; it also provides suggested bitrate baselines by frame size and frame rate. The broader recommendations describe a two-pass workflow and, for its web/mobile example, 240 frames between keyframes. These are Google’s technical starting points for file-based encoding—not settings required by YouTube or a recipe for live streams. Google’s VP9 VOD encoding settings
Use the guidance in context: the settings are aimed at broad web and mobile distribution and do not cover every content type, live use, or specific device and network constraint. Resolution and frame rate, number of renditions, desired quality, and encoding speed all affect the right choice. Larger frame sizes can improve image detail, but require more delivery bandwidth and processing power to decode.

Why YouTube may use VP9 for playback
YouTube’s current help page gives a practical viewer-facing reason to care about VP9: “To view new 4K uploads in 4K, use a browser or device that supports VP9.” This describes playback compatibility; it does not say creators must upload VP9 or can force YouTube to serve it.
Google’s historical context is useful but should be read as historical. In a post dated April 6, 2015, Google said YouTube had started encoding videos in VP9 and reported that viewers had watched more than 25 billion hours of VP9 video in the preceding year. Those were company-reported figures from that period, not current viewing totals or a present-day independent codec comparison. Google’s April 6, 2015 post on VP9 and YouTube
Common VP9 and YouTube misconceptions
- “I need to export VP9 for YouTube 4K.” YouTube’s upload recommendation names H.264. Its VP9 statement concerns viewer support for playback of new 4K uploads.
- “A higher resolution guarantees VP9.” The cited YouTube guidance does not establish that an upscale, resolution choice, subscriber count, or export setting guarantees a playback codec.
- “VP9 always cuts the bitrate in half.” Google says “as much as 50%”; it is not a promise for an individual source or workflow.
- “Google’s VOD settings are live settings.” The cited VP9 recommendations are for file-based encoding and explicitly do not supply a live-encoding recipe.
- “If YouTube recommends H.264, viewers never get VP9.” Upload encoding and playback encoding are separate stages; YouTube’s viewer guidance explicitly mentions VP9 for new 4K playback.
Copyright, reused content, and codec choice
VP9 is a compression choice, not a way to establish rights to footage, music, or other material. Encoding or re-encoding content does not make copyrighted material yours or guarantee that YouTube will accept or monetize it. Use material you created, licensed, or otherwise have permission to use, and review YouTube’s current policies when rights or monetization are in question. A codec choice also does not determine whether a channel meets YouTube’s reused-content or monetization requirements.
