Compare Video Codecs in Real Time — H.264 vs HEVC vs AV1 (enccompare)
Which codec looks best at your bitrate? enccompare transcodes and compares up to three encodings against your source side-by-side — live, with no pre-encoding. Scrub, zoom, and see exactly where each codec loses quality.
Instead of exporting a dozen test files and squinting at them, enccompare encodes a short window around the playhead on the fly, so you can compare H.264, HEVC and AV1 the moment you drop a clip in.
In this 20-second demo:
• Encode 3 codecs at once (NVENC HEVC, SVT-AV1, and more) — no waiting for a full export
• Zoom & pan all panes in perfect sync to inspect fine detail
• Difference & heatmap views that reveal exactly where the encoder throws away detail
• A/B wipe: drag a divider between the source and an encode
• Live PSNR, SSIM and VMAF quality metrics per pane
• Rate-distortion sweep: plot quality vs bitrate and find the efficiency knee for your footage
