Upscaling to 8K: mostly, don’t
8K has 16 times the pixels of 1080p and four times 4K. There are a few good reasons to make it, and many more reasons to stop at 4K.
Short answer
Only upscale to 8K if the output is shown on an 8K display or LED wall, or a client asked for an 8K master. For everything else, a clean 4K master looks the same to viewers and is a quarter of the work.
The numbers
| Resolution | Pixels | Megapixels | vs 4K |
|---|---|---|---|
| 4K UHD | 3840 × 2160 | 8.3 | 1× |
| 8K UHD | 7680 × 4320 | 33.2 | 4× |
YouTube recommends 80–160 Mbit/s for 8K SDR uploads at 24–30 fps and 120–240 Mbit/s at 48–60 fps (YouTube Help, checked 14 Nov 2026). At 120 Mbit/s a ten-minute video is about 9 GB.
When 8K does make sense
- LED walls and large-venue screens whose native canvas is 8K or wider.
- Re-framing: you need to crop a 4K window out of a wide shot in post.
- A client deliverable that specifies 8K.
If you do it
- Start from the best 4K master you can make. 8K from 1080p is 4×, and any weakness shows.
- Test a 10-second excerpt. Render time scales with pixels, so 8K costs roughly four times as much as 4K.
- Export HEVC or AV1, 10-bit. H.264 encoders and players often can’t handle 8K.
- Check playback on the target device. Many computers can’t decode 8K smoothly.

FAQ
Can I watch 8K on a 4K TV?
It will be downscaled to 4K. You might see a slight benefit from the higher bitrate, but not from the extra pixels.
How big are 8K files?
At YouTube’s recommended 80 Mbit/s for 8K SDR at 24–30 fps, one minute is about 600 MB; at 160 Mbit/s it’s about 1.2 GB. Use the bitrate calculator for your own numbers.
