# Simam Neural Codec Lab

An evidence-first video compression observatory for immersive media. Upload a short clip to inspect its source properties and compare practical AV1, H.264, and HEVC encodes when the host FFmpeg build supports them.

This is a measurement baseline, not a claim that a learned codec is universally better. The next research adapter is planned around open projects such as CompressAI and Microsoft's DCVC family.

## What it measures

- encoded size and bitrate;
- encode time and approximate real-time factor;
- decoded resolution and duration;
- a transparent quality proxy (PSNR when available);
- compatibility notes for XR playback.

Keep clips short while exploring. Results depend on the host FFmpeg build and are not a substitute for a controlled VMAF/LPIPS benchmark.

`examples/sample_codec.mp4` is a small synthetic clip for a repeatable first run.
