Q1View is a Windows toolkit for engineers who need to look at the actual pixels — raw frame buffers, codec output, decoded images, and the small visual differences that ordinary media players gloss over.

Q1View is built for people whose work depends on what individual pixels look like and how two outputs differ — not for browsing a photo library.
- Codec and video engineers validating encoder/decoder output against a reference, frame by frame.
- Imaging engineers verifying camera pipelines, color-space conversions, and ISP tuning against raw buffer dumps.
- Computer vision engineers comparing pre- and post-processing stages or inspecting model input/output frames.
- QA and validation engineers confirming regressions, picking out off-by-one pixel shifts, and checking timing behavior on real material.
- Researchers stepping through experiment outputs and capturing exact pixel values for reports.
- Inspect a raw YUV or RGB dump at any subsampling or bit depth, including odd-width sources, and read source-native channel values at the cursor.
- Compare a reference image against a processed result with PSNR and SSIM overlaid and a pink pixel-diff highlight showing exactly where they disagree.
- Step through an image sequence in a folder (
frame_001.png…frame_100.png) or a video, with synchronized navigation across two to four sources. - Pull a clipboard screenshot in and check pixel coordinates, hex values, and small color drifts.
- Drive two Viewer windows in sync to compare different decodes of the same source while panning and zooming as one.
Q1View is not intended to manage photo libraries or replace a consumer video player. It is focused on codec development, imaging validation, and quick frame-level investigation.
Open an image, raw dump, sequence, or video; zoom down to pixels, inspect coordinates and values, step through frames, or link multiple Viewer windows.
Open two to four sources side by side and see a visual difference together with objective similarity measurements.
