What is DiffALL?
DiffALL compares any two media files and pinpoints every difference. Upload expected and actual — video, audio, images, subtitles (SRT/VTT), or text/JSON — and get a similarity score in seconds.
For video it scans every second, overlays an SSIM heatmap, auto-aligns clips that start a few frames apart, and shows the exact moment of the worst difference with an annotated screenshot. Audio gets spectrogram diffs, images get pixel-level heatmaps with difference boxes (plus a rotation/lighting-tolerant mode), subtitles get Word Error Rate and timing drift, JSON gets a structural diff.
Unlike text-only diff tools, DiffALL is built for media QA: encoding checks, visual regression, render verification. 50 free comparisons a day with no signup, and an HTTP API for CI pipelines.
