Identity

Identity is a Linux application for comparing images and videos, published by Ivan Molodetskikh under the GPL-3.0-or-later. The task it names — putting two or more pieces of visual media side by side to see how they differ — comes up when checking an encode against its source, reviewing the output of a filter or upscaler, or deciding between two exports of the same footage.

Only a Linux build is listed in this record. There is no Windows or macOS entry here, so the program is of use mainly on a Linux workstation, and someone comparing renders on another operating system would need an alternative. The GPL-3.0-or-later terms make the source available and require the same licence on modified copies.

The metadata does not state which container and codec formats are accepted, how many files can be loaded at once, whether frame-accurate seeking or synchronised playback is offered, or what comparison views exist. Those details belong to the project's own documentation and should be read before relying on it for encoding or grading work.
