(Optional)

bframes?

number

(Optional)

calculatePsnr?

boolean

(Optional) Compute per-frame PSNR while encoding and attach it to each frame’s quality metrics. Cheap. Reported for both single-rendition and multi-rendition (ABR ladder) encodes. Off by default.

calculateVmaf?

boolean

(Optional) Compute VMAF while encoding and attach it to each frame’s quality metrics. Expensive (per-frame inference), so off by default. The value is a running mean rather than a strict per-frame score. VMAF is only produced for single-rendition encodes — MainConcept does not emit it for a multi-rendition (ABR ladder) encode, where it is simply absent. MainConcept does not compute SSIM.

cpuList?

number[]

(Optional) CPUs to assign to this instance of MainConcept, absent/empty array means use all CPUs
