Hello, I have extensive experience building and optimizing AV1-based video compression pipelines, including work with SVT-AV1 and AV1-nvenc, FFmpeg automation, VMAF-driven QA, and GPU-accelerated encoding on RTX-class hardware. My solution is a modular Python + FFmpeg pipeline that combines fast scene detection and classification, adaptive per-scene encoding profiles (SVT-AV1 on CPU and AV1-nvenc where appropriate), and an iterative VMAF-guided rate-control loop with lightweight quality prediction to minimise re-encodes. I will provide performance-tuned configs, benchmarking scripts for 4K/1080p chunks on RTX4090-class hardware, VMAF reports, and full documentation so the pipeline meets the 30-second per-chunk target and the specified compression/VMAF goals. Looking forward to working with you! Can we discuss this further via private chat? Warm regards, Alesha

✋ Hi there. I can develop a full video compression pipeline using AV1 that achieves high compression rates while maintaining VMAF quality thresholds. ✔️ I have strong experience with AV1 encoding (SVT-AV1 and AV1-nvenc), FFmpeg automation, and Python scripting for video processing. I previously built pipelines that handled 4K and HD videos, optimized CQ and bitrate settings, and ensured VMAF scores above 90 while achieving compression ratios above 5x. ✔️ For your project, I will design an end-to-end workflow including scene detection, adaptive encoding based on content type, and GPU-accelerated processing for speed. Each video chunk will be analyzed, encoded, and tested against VMAF targets, with performance benchmarks documented for every run. ✔️ I will provide scripts, configuration files, and detailed instructions to reproduce results. The system will support MP4 outputs, yuv420p pixel format, and maintain the 30-second processing requirement per 30-second 4K segment. Let’s chat so I can review your sample videos and outline the optimal encoding approach. Best regards, Mykhaylo

Hello, June, I will build an AV1-based compression pipeline tuned for 4K and 1080p that meets your VMAF and speed targets. Approach: implement SVT-AV1 (with AV1-nvenc fallback) driven by FFmpeg wrappers, add scene-detection/classification (lightweight CNN) to choose per-scene CQ/bitrate presets, and integrate VMAF-driven QC and a quality predictor to avoid costly re-encodes. For performance, I’ll parallelize 30s chunk processing and tune encoder knobs for an RTX 4090 baseline to achieve 20–30s per chunk while targeting 5–20x compression and VMAF 85–93. To start I need sample 4K/1080p clips, your exact VMAF thresholds per content, and access to baseline hardware or logs. I’ll deliver a working prototype and initial benchmarks in 7 days and the complete pipeline, docs, and VMAF reports in 14 days. Which content categories (animation, gaming, text-heavy, live-action) do you prioritize and are there per-category VMAF targets or bitrate ceilings I should use? Best regards,
