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.

If your source is a MEL file, the conversion is in terms of picture quality. The EL track essentially contains nothing more than the RPU, which is the heart of the Dolby Vision experience. The conversion simply extracts the RPU from the EL and merges it directly with the BL, creating a standard BL+RPU Profile 8.1 file. The result is a Profile 8.1 file visually identical to the original.

No. Dedicated disc players can play Profile 7 properly. This conversion is only needed for streaming media players (Apple TV, Shield, TV Apps). Conclusion def _cleanup(self): files = [self

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.
By converting to Profile 8.1, you create a single-layer stream that retains the dynamic metadata (RPU) while discarding the extra enhancement layer (EL) that many players can't process. Popular Tools for Conversion (2026)
