Question about BL extraction in v0.74

[soundthemp3-ship-it]

I have a question about the recommended workflow in the latest DDVT v0.74.

I have an original Dolby Vision Profile 7 MKV and a Profile 8.1 RPU.bin created for that exact video.

When using DDVT_INJECTOR, do I need to manually demux the Profile 7 video and extract the HDR10 Base Layer (BL.hevc) before injecting the RPU?

Or can I simply load the original Profile 7 MKV directly into DDVT_INJECTOR and let DDVT automatically use/extract the Base Layer internally while injecting the Profile 8.1 RPU?

In other words, in the latest DDVT v0.74, is the recommended workflow:

Profile 7 MKV → manual BL demux → inject RPU, or
Profile 7 MKV → inject RPU directly (DDVT automatically handles the Base Layer internally)?

Which method is technically correct and recommended by the developer?

@DonaldFaQ Could you please answer, dude?

I have one more question about DDVT v0.74 Injector.

In the Injector menu, when I select the "Delay" option, the prompt says "Type in the RPU DELAY".

If I inject both a Dolby Vision RPU and HDR10+ metadata in the same operation, is the delay value applied only to the Dolby Vision RPU, or is it applied to both the RPU and the HDR10+ metadata?

In other words, does the single Delay setting synchronize both metadata types, or does HDR10+ use a separate delay mechanism internally?

If you choose both injections in one step, the delay will be processed on both metadatas.

If your source video is profile 7 (FEL or MEL) and you inject a profile 8 RPU, the EL Layer will be automatically erased. On end of proccessing you have a BL+RPU layer instead BL+EL+RPU.

Profile 7 MKV → inject RPU directly (DDVT automatically handles the Base Layer internally)?

This is the fastest way, but both ways will work.
