JUAN MELARA – BMPCC 4K to Alexa PowerGrade and LUTs

Created using the same process as the P6K version, P4K2Alexa features a new 3×3 matrix that accurately matches the P4K to the Alexa. This is the same method used by high-end post houses to match digital cameras. And it offerrs many advantages over using a LUT

WHAT’S INCLUDED IN THE NEW GEN5 VERSION

GEN5 LUT VERSION

Two versions of P4K2Alexa Gen5 LUT transform:

1. The P4K2Alexa_Gen5_LogC LUT outputs a LogC image and is fully compatible with any LUT or PowerGrade that expects ARRI LogC as the input. Use this if you need to match Alexa footage on the same timeline or if you need to share looks between the two cameras without modifying looks.
2. The P4K2Alexa_Gen5_BMD_Film LUT outputs Alexa colours but in Gen5 BMD Film log. The output won’t match LogC Alexa footage, but it gives you the benefit of the extra highlight range of Gen5. Which means you don’t need to manually grade highlights back down into range. Use this if you want the Alexa colours but don’t need to intercut with Alexa footage.

ARRI_LogC2Video_709 Output LUTs: The latest ARRI LogC to Rec709 LUT in two new versions. ARRI_LogC2Video_709_V2.cube and a Wide Dynamic Range (WDR) version known as ARRI_LogC2Video_709_WDR_V2.cube. These LUTs have been modified for more filmic style saturation, allowing for deeper richer colours whilst avoiding over-saturation. These LUTs are designed to be paired with the P4K2Alexa_Gen5_LogC LUT above. Also included are the previous versions of these LUTs: Standard, WDR, WDR Highlights and WDR Roll-Off.

BMD_Gen5_Film2Video_709 Output LUTs: the two new V2 LUTs from above but designed to be paired with the P4K2Alexa_Gen5_BMD_Film LUT above. They are known as BMD_Gen5_Film2Video_709_V2.cube and BMD_Gen5_Film2Video_709_WDR_V2.cube.

All-in-one Post-Production Rec709 LUTs: The P4K BMDFilm Gen5 transform combined with the two new V2 Rec709 output LUTs. Created at x65 precision.

In-Camera/On-Set Rec709 LUTs: Same as above but created at x33 precision for compatibility. Used to preview the transform on the P4K or external monitors.

P4K2Alexa Gen4 LUTs: All the Gen4 LUTs are included as well.

GEN5 POWERGRADE VERSION

Two versions of P4K2Alexa Gen5 PowerGrade transform:

1. The P4K2Alexa Gen5 LogC PowerGrade outputs a LogC image and is fully compatible with any LUT or PowerGrade that expects ARRI LogC as the input. Use this if you need to match Alexa footage on the same timeline or if you need to share looks between the two cameras without modifying looks.
2. The P4K2Alexa Gen5 BMD Film PowerGrade outputs Alexa colours but in Gen5 BMD Film log. The output won’t match LogC Alexa footage, but it gives you the benefit of the extra highlight range of Gen5. Which means you don’t need to manually grade highlights back down into range. Use this if you want the Alexa colours but don’t need to intercut with Alexa footage.

The P4K2Alexa PowerGrades allow you to adjust all aspects of the P4K to Alexa transform. You can make adjustments to the core 3×3 matrix, you can also adjust the shadow/highlight tint curve and tweak the highlight roll-off curve to taste.

P4K2Alexa RCM PowerGrade: The P4K2Alexa transform for use in Resolve Color Managed (RCM) workflows.

P4K2Alexa ACES PowerGrade: The P4K2Alexa transform for use in ACES workflows.

ARRI_LogC2Video_709 Output LUTs: The latest ARRI LogC to Rec709 LUT in two new versions. ARRI_LogC2Video_709_V2.cube and a Wide Dynamic Range (WDR) version known as ARRI_LogC2Video_709_WDR_V2.cube. These LUTs have been modified for more filmic style saturation, allowing for deeper richer colours whilst avoiding over-saturation. These LUTs are designed to be paired with the P4K2Alexa_Gen5_LogC LUT above. Also included are the previous versions of these LUTs: Standard, WDR, WDR Highlights and WDR Roll-Off.

BMD_Gen5_Film2Video_709 Output LUTs: the two new V2 LUTs from above but designed to be paired with the P4K2Alexa_Gen5_BMD_Film LUT above. They are known as BMD_Gen5_Film2Video_709_V2.cube and BMD_Gen5_Film2Video_709_WDR_V2.cube.

In-Camera/On-Set Rec709 LUTs: The P4K BMDFilm Gen5 transform combined with the two new V2 Rec709 output LUTs. Created at x33 precision for compatibility. Used to preview the transform on the P4K or external monitors.

P4K2Alexa Gen4 PowerGrades: The Gen4 PowerGrades are included as well.
