a 25% increase in bandwidth is needed to accommodate 10-bit.
In comparison, the same file compressed with QuickTime X in macOS High Sierra as HEVC/H.265 results in a file size of only 43MB
The original file is compressed 1080i59.94 ProRes LT 422 10-bit. To objectively analyze the visual quality of a file exported as both 8-bit and 10-bit, a 12-bit RAW source file must be used. Thus, no qualitative comparisons are made in this post.
