Even 8-bit 4:2:2 source footage won’t gain anything from using the larger 10-bit ProRes preset. You might be tempted to output a lower spec source file with the QuickTime preset in order to increase its quality. For this reason, we recommend using H.264 presets when you capture your source footage at 8-bit or 4:2:0. They contain setting that deliver a high-quality image in a small file – but not so small that quality becomes suspect. The Adobe Stock presets that use H.264 fall on the lower side of robustness.
Regardless of the delivery or file integrity, H.264 is a highly efficient codec that delivers excellent image quality in a relatively small package.
In other cases, it can deliver files with limited technical properties for ease of delivery over the web and streaming platforms. Sometimes the H.264 compression scheme is used to create very robust file formats that support high-end needs similar to ProRes.
H.264 covers a broad range of applications and codecs.
