2026-10-10 03:46:36 +00:00 | 43 commits to master since this releaseThe first release of mcap: a library of screenshots, photos and videos, each kept as one
.mcapfile, read with OCR, labelled, segmented and searchable.What's new
Videos and animated GIFs
- Import: MP4, MOV, MKV, WebM, AVI, WMV, MPEG and FLV import like photos (via FFmpeg). Each is stored whole, with a poster frame for the grid, OCR and labels. The date, device and location come from the video's own metadata.
- Grid and Capture window: thumbnails show a play mark and duration (videos) or GIF. Play in the default player opens the original.
- Any size: videos are copied a few MB at a time, never read whole into memory. This needs
.mcapfile version 4 (versions 1–3 still open).
Segmentation: what's in each image
- Choose folders: the Segments window has a checkbox per library folder; nothing is segmented unless you tick its folder. Uses Mask2Former (Swin-B, 133 COCO classes): people, animals, things, and sky, wall, grass and so on.
- Search:
has:dog,has:"dining table",has:person has:"cell phone". - Stats: What is in the images lists how many images hold each class; click one to search for it.
- Capture window: segments drawn over the image. Opacity, a legend to hide classes, colours you can pick, and hover for class and score.
- Speed: about 17 images a second on an RTX 5080 laptop, about 5 KB stored per image.

Also
- Shutdown: closing the app says what it's waiting on, and stops an OCR scan mid-batch instead of finishing it.
- Fixes: a crash importing videos of some frame sizes, and a crash on exit.
Download
mcap-0.1.0-windows-x64.zip, for Windows 10 and 11 (x64). Unzip anywhere and runmcap.exe; nothing to install.- Size: 2.2 GB zipped, 3.0 GB unpacked.
- Included: onnxruntime, FFmpeg, the OCR, label and segmentation models, and NVIDIA's CUDA 13 runtime and cuDNN 9.
- GPU: on an NVIDIA GPU (RTX 20 series or newer) with a current driver, OCR, labels and segmentation run on the GPU. Otherwise they run on the CPU, which is slower but works the same.
- Library folder: the library defaults to
D:\McapIndex\mcap. Point it elsewhere with-library "E:\My library"(seeREADME.txt).
