A script to batch combine HDR media with Dolby Vison media for a hybrid file that uses Dolby Vision but with fallback to HDR. The script has a bulit in frame compare tool that makes syncing the different files very easy. The script matches the files by comparing frame count because Dolby Vision RPU-files are based on frames, not on time.

FFmpeg needs to be installed to path
requirements.txt needs to be installed with pip

DV_HDR_Merge.py [Input files/folders]

Optional commands: --help, -logL, -maxdif

DV_HDR_Merge.py -logL debug -maxdif 100 HDR_movie.mkv DV_movie.mp4 HDR_movie2.mkv DV_movie2.mkv ./DV_movie_folder ./HDR_movie_folder

Valid input formats:
HDR media: *.mkv
Dolby Vision media: *.mkv, *.mp4

Can be customized to use *.mp4 as HDR input as well but Matroska is the superior container.

Output format: *.mkv

Shift frames:
A negative amount means that frames will be removed in the beginning and a positive means that the first frame will be duplicated to add enough frame. Any excess frame on the end will be cut off

General:
If frame dimensions do not match the script will automagically correct for it.

1. Opens the active image in your default photo application for easier inspection
2. Switches between a 50/50 blend of the two compared images or a greyscale difference
3. Set the frame to refrence in the HDR media file, press Enter to apply. (Total amount of frames in media is shown in label)
4. Set how may frames to shift Dolby Vision layer with, press Enter to apply.
5. Closes window and sends inputed frame-shift to be used when combining the two media.
   (Closing the window will do the same as the Done button)

Always compare multiple refrence frames in case of missing or extra frames in some of the materials used.

Both senarios are using frame 30000 as the HDR refrence frame.

• When extracting, modifying and injecting the RPU file no live progress is shown because of a problem catching output from dovi_tool
