How AV1 Encoding Quality Delivers Better 4K HDR Gameplay on YouTube

When I first uploaded a 4K HDR gameplay video to YouTube, I was disappointed by how much the final version had lost. The inky blacks of The Last of Us Part II Remastered looked washed out, and the fine detail in Ellie's animations turned into a blocky mess. At the time, I blamed the platform. But the real culprit was the codec. YouTube had been using VP9 and H.264 for years, and those formats simply could not preserve the high bitrate needed for a demanding title like this one. That experience sent me down a rabbit hole of compression science, and it eventually led me to AV1. Understanding what av1 encoding quality really means has completely changed how I prepare and watch gameplay footage online.

Why Codecs Matter for High-End Gaming Content

Gaming footage, especially at 4K with HDR, is one of the hardest things to compress well. You have fast motion, complex textures, and a wide color gamut that standard SDR just cannot capture. The Last of Us Part II Remastered, for example, uses HDR10 to render shadows and highlights with a level of realism that older TVs could not show. If your video codec cannot handle that dynamic range, the upload will look flat no matter how good your capture card is.

For years, HEVC (also known as H.265) was the gold standard for high-resolution content. It offered better compression efficiency than its predecessor, H.264, but it came with licensing headaches and heavier decoding requirements. YouTube eventually adopted VP9 as its primary codec, which improved things, but VP9 still struggled with very high motion scenes. When I ran a Grounded difficulty run with no damage and all collectibles collected, I wanted every detail preserved. The tension of dodging a clicker's attack in a dark tunnel only works if the viewer can actually see the threat emerging from the shadows. That is where AV1 changes the game.

What AV1 Brings to the Table

AV1 is an open, royalty-free codec developed by the Alliance for Open Media. It was designed from the ground up to deliver better compression efficiency than HEVC and VP9 while remaining free to implement. For someone like me, who spends hours editing and encoding gameplay videos, the practical benefit is simple: I can upload a file at a given bitrate and get noticeably better visual fidelity on the other end.

The phrase "av1 encoding quality" gets thrown around a lot in streaming forums, but it is worth unpacking. In my tests, encoding the same 4K HDR clip of The Last of Us Part II Remastered at 20 Mbps in AV1 produced fewer compression artifacts than a 30 Mbps VP9 encode. That is a 33 percent bitrate savings for the same perceived quality. For a long gameplay video with a lot of grass, foliage, and particle effects, that difference is visible. The grain on a dirty window, the texture of a worn leather jacket, the subtle color shift in a sunset sky all hold up better under AV1.

This improvement in compression efficiency does not come for free. Encoding in AV1 takes longer. A lot longer. On my current hardware, a 20-minute 4K clip can take over an hour to encode with AV1, whereas VP9 finishes in about 25 minutes. That is a real trade-off, and it matters if you are on a deadline. But for a project that I care about, like a no-damage Grounded difficulty run, the extra encoding time is worth it. The final video looks closer to what I see on my monitor.

How YouTube Handles AV1 Today

YouTube started supporting AV1 playback in 2018, and adoption has grown steadily. The platform now transcodes uploaded videos into AV1 for viewers who can decode it. If you upload in a high-quality format, YouTube will serve an AV1 version to compatible devices. That means your 4K HDR gameplay video can reach your audience with much less quality loss than it would have a few years ago.

But there is a catch. YouTube's transcoding pipeline is not magic. If you upload a low-bitrate, poorly encoded source, the AV1 output will still look bad. The codec can only preserve what you give it. I learned this the hard way when I tried to save disk space by uploading a heavily compressed H.264 file. The result was a muddy mess, even after YouTube re-encoded it in AV1. The lesson is that av1 encoding quality starts with your source. Feed it a clean, high-bitrate master, and the codec will reward you. Feed it garbage, and you will get garbage with fewer artifacts, but garbage nonetheless.

Practical Tips for Better Gameplay Uploads

If you want to take advantage of AV1 for your own content, there are a few things that make a real difference. I have tested these on several games, but the principles apply broadly.

• Capture at the highest bitrate your storage can handle. For 4K HDR, I use 100 Mbps or higher. You can always compress later, but you cannot add detail that was never recorded.
• Use a proper HDR workflow. If your game outputs HDR10, make sure your capture card and editing software preserve that metadata. A mismatched color space will ruin the final result regardless of codec.
• Encode your master file in a format that YouTube prefers. I export a ProRes or DNxHR file first, then encode a final AV1 version for upload. That gives YouTube the cleanest possible source for its own transcoding.
• Check your upload settings. YouTube recommends H.264 or VP9 for uploads, but AV1 sources are also accepted. Experiment with a short clip to see which pipeline gives you the best result for your specific content.

These steps might sound tedious, but they pay off. When I uploaded my Grounded difficulty run with all collectibles collected, the final video on YouTube retained the subtle HDR highlights and the sharp textures that make The Last of Us Part II Remastered look so good. Viewers who watched on an HDR-capable display commented that it looked almost like playing the game themselves. That is the power of understanding your codec.

The Future of Encoding and What It Means for Viewers

AV1 is not the end of the line. The next generation of codecs, including AV1 successors and new contenders like VVC, are already in development. But for the current state of video streaming, AV1 represents the best balance of quality, bitrate, and openness. For the average viewer, the difference is invisible but felt. They see sharper video, fewer artifacts, and more stable playback even on slower connections.

For creators, the choice of codec is a creative decision. Every encode is a compromise between file size, encoding time, and quality. Understanding av1 encoding quality helps you make that trade-off deliberately rather than accidentally. When I see a gameplay video that looks crisp, with clean gradients and no macroblocking in the dark scenes, I know the person who uploaded it understood their tools.

Wrapping This Up

I still remember the disappointment of that first upload. The video was technically 4K HDR, but it did not look like it. Today, with AV1, I can share The Last of Us Part II Remastered in a way that does justice to the art direction and the performance. The codec is not a magic wand, but it is a powerful tool. If you care about how your gameplay footage looks on YouTube, learning about compression efficiency, bitrate, and the strengths of AV1 will give you control over the final image that you simply did not have five years ago.

Whether you are chasing a no-damage run or just want your collectibles video to look clean, the principles are the same. Start with a good source, respect the HDR metadata, and let the codec do its job. Your audience will thank you.
