wtf is framedeck?

FrameDeck is a portable review player built for visual effects artists to check shots before they are finalized. It runs on Windows and Ubuntu as a standalone download, no installation required beyond extracting a zip file or running an AppImage. The project builds on an earlier tool called Viewline and adds an editorial review workflow, color management, and annotation tools aimed at professional VFX pipelines. A user can import many video and image formats at once, including MP4, MOV, AVI, and EXR image sequences, then arrange them into a playlist that plays back as one continuous timeline. Two sources can be compared side by side using modes like a wipe, overlay, difference, or flicker view, which helps when checking a new version of a shot against an older one. The player also reads EXR image layers, which are the separate technical passes that make up a rendered VFX shot. FrameDeck includes OCIO color management, a system used in film and VFX to keep colors consistent across different cameras and displays, along with built in ACES color configurations, which is an industry standard color pipeline. Reviewers can draw pencil or text notes directly on a frame, leave frame-by-frame comments with a resolved or open status, and export those comments to CSV or a searchable PDF report. Annotated frames can also be exported as images, and full sequences can be converted into an MP4 video file. Playback is built to handle heavy files, with background caching, buffering for 2K and 4K footage, and support for many video codecs through FFmpeg. The interface includes keyboard shortcuts for zoom, pan, gamma and exposure checks, and full screen review. Portable builds for both Windows and Ubuntu are produced automatically through GitHub Actions. The README references that FrameDeck keeps the history and license of the Viewline project it was built on, without stating what that license is.
