    SDR to HDR Conversion

    Hybrik supports stitching SDR and Dolby Vision sources together into Dolby Vision Profile 5 and Profile 8.1 outputs. This can be enabled by setting convert_to_dolby_vision in your Dolby Vision transcode targets. This feature was introduced in Hybrik version 1.245.

    "dolby_vision": {
        "profile": "5",
        "convert_to_dolby_vision": {
            "mode": "simple_conversion"
        }
    }
    

    Currently, we support a simple_conversion mode that maps the maximum brightness of SDR clips to 205nits (this will be configurable in a future update). This mode is appropriate for bumpers, title cards, and ads, and is not meant for high-value content. An enhancement mode that provides more accurate content-aware conversions suitable for higher-value content will be made available in a future update.

    Known Limitations

    • All sources must have matching frame rates
    • SDR sources must contain colorspace metadata
    • auto_generate_silent_tracks must be set if any source does not have audio tracks to match the target’s audio track configuration

    Troubleshooting

    • If your job fails with the error "This job requires a script task job_modifier to compile. Please contact Hybrik Support for assistance.", please check that your segmented_render job_modifier script task is configured correctly. Also check that all of your source assets have the same frame rate.

    • If your job fails with the error "pipeline error: DOVI_PREPROC ERROR: nutio nutio_get_per_frame_colorinfo: color format unsupported (errc: 7)", please check that your SDR source contains color data (Color primaries, Transfer characteristics, and Matrix coefficients) in mediainfo.
