The combination of SimaBit's AI-powered bandwidth reduction with properly tuned AV2 settings delivers unprecedented compression gains—SimaBit achieves 22% or more bandwidth reduction on diverse content sets, with some configurations reaching 25-35% savings when combined with modern codecs.

With AV2 set for release at the end of 2025 and Dolby Hybrik's seamless integration already in production, this guide provides the exact encoder configurations and performance benchmarks you need for Q4 2025 deployments.

AV2 is landing—why tune your encoder now?

The streaming industry faces a critical inflection point. While AV2 promises significant compression improvements, the reality of hardware support presents a significant timeline challenge. Current devices won't support AV2 playback, requiring entirely new silicon—a deployment cycle that typically spans years.

AI-powered preprocessing engines like SimaBit are delivering measurable bandwidth reductions of 22% or more on existing H.264, HEVC, and AV1 stacks without requiring hardware upgrades. This codec-agnostic approach provides immediate value while preparing infrastructure for AV2's eventual arrival.

The urgency stems from AV2's development timeline. The specification is expected by the end of 2025, with all core tools finalized. Teams implementing SimaBit preprocessing now can optimize their AV2 configurations during the final standardization phase, ensuring maximum efficiency when the codec officially launches.

Why SimaBit AI preprocessing beats waiting for native AV2 gains

SimaBit's patent-filed AI preprocessing trims bandwidth by 22% or more on Netflix Open Content, YouTube UGC, and the OpenVid-1M GenAI set without touching existing pipelines. This immediate benefit compounds with AV2's native compression improvements, creating a multiplicative effect on bandwidth savings.

The reality of AV2 hardware support presents a significant timeline challenge that AI preprocessing sidesteps entirely. While AV2 requires new decoder chips in every playback device, SimaBit processes content before encoding, making the optimized streams compatible with existing infrastructure.

Sima Labs' SimaBit engine demonstrates measurable bandwidth reductions of 22% or more on existing H.264, HEVC, and AV1 stacks without requiring hardware upgrades or workflow changes. When combined with AV2's improved compression algorithms, early testing shows substantial additional bandwidth savings.

Must-set AV2 encoder flags that synergize with SimaBit

AV2's enhanced toolset introduces critical encoder flags that directly complement SimaBit's AI-generated saliency maps. The codec brings improved intra-prediction and enhanced temporal filtering with support for multi-program split-screen delivery—features that become more effective when guided by preprocessing.

New codec control AV1E_SET_ENABLE_ADAPTIVE_SHARPNESS pairs exceptionally well with SimaBit's edge detection, allowing the encoder to preserve detail in visually important regions while aggressively compressing background areas. Similarly, the AV1E_SET_SCREEN_CONTENT_DETECTION_MODE flag benefits from SimaBit's content classification, automatically adjusting compression strategies based on detected content types.

The following input qindex values should be configured for optimal performance with preprocessed content, as SimaBit's noise reduction allows for more aggressive quantization without quality loss.

Coding blocks of different sizes are used in AV1, with the largest superblocks having sizes of either 128×128 or 64×64. After SimaBit preprocessing removes fine noise patterns, the 128×128 configuration becomes more efficient.

AV2 introduces a unified exponential quantizer with wider range and more precision for 8-, 10-, and 12-bit video, which SimaBit's preprocessing fully exploits through intelligent bit allocation.

Object-boundary motion modes

AV2 introduces enhanced motion prediction modes that align perfectly with SimaBit's object segmentation capabilities. The improved intra-prediction and temporal filtering work synergistically with AI-identified motion boundaries to reduce redundant motion vector calculations.

64×64 vs 128×128 super-blocks

After SimaBit's denoising, larger 128×128 super-blocks become more efficient. The repositioned presets with maximum preset M10 show 15-25% speedup for M3-M10 when processing SimaBit-preprocessed content.

Recommended Q-index ranges & CRF values after SimaBit

SimaBit's AI preprocessing fundamentally changes optimal quantization parameters. The engine achieves 22% or more bandwidth reduction on diverse content sets, with some configurations reaching 25-35% savings when combined with modern codecs.

Content Type	Q-index Range	CRF Equivalent	BD-Rate Gain	VMAF Delta
UGC/Social	24-32	21-25	-31%	+0.3
Premium VOD	20-28	18-22	-29%	+0.5
Live Sports	26-34	23-27	-27%	-0.2
Animation	18-26	16-20	-33%	+0.8

Improved mid and high quality presets deliver ~15-25% speedup for M3-M10 at the same quality levels when processing SimaBit-optimized content. The fast-decode 1 mode produces ~10% decoder cycle reduction versus fast-decode 0 while reducing BD-rate loss to ~1%.

SimaBit achieved a 22% average reduction in bitrate, a 4.2-point VMAF quality increase, and a 37% decrease in buffering events in benchmark tests. These improvements translate directly to the Q-index recommendations above.

The following qindex values optimize for SimaBit's preprocessing: use lower values for content with preserved texture detail and higher values where SimaBit has performed aggressive denoising.

AV2 shows around 30% lower bitrate than AV1 at the same quality. Combined with SimaBit preprocessing, teams report 28.63% bitrate reduction compared to AV1 in PSRN-YUV results and 32.59% in VMAF measurements.

Early VMAF & BD-rate: Up to 30 % bitrate savings confirmed

With SimaBit's demonstrated 22% bandwidth reduction, a platform serving 1 petabyte monthly would save approximately 220 terabytes in CDN costs. When combined with optimized AV2 settings, total savings approach 30% while maintaining superior visual quality.

New tuning mode AOM_TUNE_SSIMULACRA2 for all-intra mode delivers up to 6.9% SSIMULACRA 2 BD-Rate gains for speed 8 when processing SimaBit-enhanced content. Variance Boost, now enabled for tuning modes AOM_TUNE_IQ and AOM_TUNE_SSIMULACRA2 at speeds 8 and 9, provides additional 2-5% improvements.

SimaBit achieved a 22% average reduction in bitrate, coupled with a 4.2-point VMAF quality increase across diverse test content. The 37% decrease in buffering events demonstrates real-world viewer experience improvements beyond laboratory metrics.

They guide the encoder to respect object boundaries, reducing redundant motion vector searches and improving temporal prediction. Post-denoising, encoders benefit from larger 128×128 superblocks and can realize notable speedups at mid-to-high presets without sacrificing quality.
