8-Bit vs 10-Bit Video: Banding, File Size, Platforms

8-bit video stores 256 levels per colour channel; 10-bit stores 1,024. That's 16.7 million possible colours against about 1.07 billion. The extra steps matter in smooth gradients, where 8-bit can show visible bands, and when you grade log or HDR footage, which stretches the levels apart. For a finished SDR video posted to social media, 8-bit is normal and usually indistinguishable; 10-bit is for shooting, grading and HDR delivery.

Below: the numbers side by side, what it does to file size, which codecs and platforms carry 10-bit, and how to check and convert a file. Checked on 1 November 2026 against YouTube Help, Vimeo Help, Meta's engineering blog, Apple's ProRes white paper and the FFmpeg and HandBrake documentation. More in our video formats, codecs and numbers guides.

The short answer

10-bit video has 1,024 shades per channel instead of 256, so gradients band less and footage survives colour grading better. Shoot 10-bit if you'll grade log footage or deliver HDR; export 8-bit H.264 for ordinary SDR uploads, since most platforms deliver SDR in 8-bit. At the same bitrate, a 10-bit file is the same size; uncompressed, it's 25% larger. For 10-bit delivery use HEVC Main 10, VP9 Profile 2 or AV1, which is what YouTube recommends for HDR.

Key takeaways

• 8-bit: 256 levels per channel, 16.7 million colours. 10-bit: 1,024 levels, about 1.07 billion.
• The visible benefit is less banding in skies, walls and fades, and more headroom when grading log footage.
• HDR needs 10-bit: YouTube asks for 10 or 12 bits, Vimeo for 10 or more.
• File size follows bitrate: same bitrate, same size. Uncompressed 10-bit is 25% bigger.
• Most finished SDR video is delivered as 8-bit; 10-bit survives mainly as HDR on YouTube, Vimeo and Instagram.

What is the difference between 8-bit and 10-bit video?

The difference is how many brightness steps each colour channel can store. Each extra bit doubles the steps, so 10-bit has four times as many as 8-bit per channel, and 64 times as many colour combinations overall.

The colour counts are arithmetic: 256³, 1,024³ and 4,096³. Video normally uses a limited range for brightness, which is why 8-bit has 220 usable luma steps rather than 256. Bit depth is separate from chroma subsampling (4:2:0, 4:2:2): a file can be 10-bit 4:2:0 like a phone's HDR video or 10-bit 4:2:2 like ProRes 422.

When can you see the difference?

You see the difference in smooth gradients and after heavy grading. On a blue sky, a plain wall lit from one side or a slow fade to black, 220 steps of brightness spread over the frame can show as visible bands. With 877 steps the bands are four times narrower and usually disappear.

• Banding: most visible in skies, studio backdrops, vignettes and dark scenes.
• Grading log footage: log profiles squeeze a wide brightness range into the file. Stretching it back out spreads 8-bit levels apart and exposes gaps; 10-bit has room to spare.
• HDR: needs 10-bit. YouTube's HDR page asks for 10 or 12 bits, and Meta's engineering blog notes HDR uses 10 bits per colour component.
• Ordinary SDR viewing: a well-encoded 8-bit file of normal footage looks the same to most viewers.

If you only have 8-bit and see banding, a little film grain or noise in the edit breaks up the bands, because the encoder can't draw clean steps through random texture.

Is 10-bit video bigger? File size compared

A 10-bit file is not bigger at the same bitrate. Compressed file size is the bitrate times the length; bit depth only changes how well those bits describe the picture. Video file size per minute shows the formula.

Where 10-bit costs space is uncompressed and intermediate video: 10 bits instead of 8 is 25% more data, so uncompressed 1080p30 4:2:0 goes from about 5.6 GB to 7.0 GB a minute. Cameras that record 10-bit also tend to choose higher bitrates, which is why their files are larger, not the bit depth itself. ProRes 422 HQ, for example, is 10-bit 4:2:2 at a much higher rate than any delivery codec; see ProRes vs H.264.

Which codecs support 10-bit?

The FFmpeg H.264 guide notes that 8-bit is more common among distributors, and that you can see which you're getting from the pixel format in FFmpeg's output: yuv420p is 8-bit, yuv420p10le is 10-bit. HandBrake lists x264, x265, SVT-AV1, VP9, Apple VideoToolbox, Intel QuickSync and Nvidia NVEnc as encoders that can write 10-bit; you choose a "10-bit" encoder from the Video Encoder list. More on the codecs in H.264 vs H.265 and AV1 vs HEVC.

Which platforms keep 10-bit video?

Platforms keep 10-bit mainly when the upload is HDR. For SDR, YouTube's live encoder page lists 8-bit, and we found no platform that promises to deliver an SDR upload in 10-bit.

So for a normal Reel or Short, a 10-bit SDR export gains nothing after the platform re-encodes it. HDR is its own topic: see HDR video on social media.

How to check bit depth and convert 10-bit to 8-bit

1. Open the file in MediaInfo: under Video, Bit depth says 8 or 10 bits. Or run ffprobe -v error -select_streams v:0 -show_entries stream=pix_fmt in.mov and look for 10le in the result.
2. If the file is 10-bit SDR, convert to 8-bit H.264 with ffmpeg -i in.mov -c:v libx264 -pix_fmt yuv420p -crf 18 -c:a aac -b:a 192k out.mp4.
3. If the file is HDR (MediaInfo shows BT.2020 with PQ or HLG), changing the pixel format alone gives washed-out colour; it needs tone mapping to SDR, covered in the HDR guide linked above.

For a smaller copy to share rather than a master, QuickVeed's free video compressor makes 1080p, 720p or 480p versions in your browser without uploading the file.

Frequently asked questions

Is 10-bit video better than 8-bit?

It has four times as many levels per channel, so it bands less and grades better. For a finished SDR video on social media, viewers rarely see a difference.

Does 10-bit video take more space?

Not at the same bitrate. Uncompressed, it's 25% more data, and 10-bit cameras often record at higher bitrates.

Does YouTube support 10-bit?

Yes, for HDR uploads, which must be 10 or 12-bit. SDR delivery is 8-bit on its live encoder page, and YouTube doesn't promise 10-bit for SDR uploads.

Does Instagram support 10-bit?

For HDR Reels, yes: Meta's engineering blog describes keeping HDR uploads and making SDR copies for devices without HDR.

Can H.264 be 10-bit?

Yes, with the High 10 profile, but it's uncommon; HEVC Main 10, VP9 Profile 2 and AV1 are the usual 10-bit delivery codecs.

Should I shoot 8-bit or 10-bit?

10-bit if you shoot log, plan to grade or deliver HDR; 8-bit is fine for straight-to-social clips you won't grade.
