If you want, tell me what files you have (container type, whether you have the original RPU/SEI or only an MP4/HLS stream) and I’ll produce a concise, specific command-by-command workflow for your situation.

Ensure the base layer is HDR (BT.2020). If the base layer is SDR (rare in P7, but possible in other profiles), converting to P8 requires tone mapping. For this specific P7->P8 request, we assume the Base Layer is already HDR.

Designed for physical media, it contains a Base Layer (BL), a Reference Picture Unit (RPU) for dynamic metadata, and an Enhancement Layer (EL).

After conversion, confirm the new profile:

Profile 7 files come in two flavors: MEL (Minimum Enhancement Layer) and FEL (Full Enhancement Layer). While both can be converted, discarding the FEL means losing some 12-bit luminance expansion, though most modern TVs still display the resulting Profile 8.1 beautifully.
