FrameTrellis v1.2.2: Faster H.264 Exports, Smarter Resolution Controls, and Improved Rendering Feedback

FrameTrellis v1.2.2 is now available as a stable release.

FrameTrellis is a free, open-source, local-first desktop video editor built with C++20, Qt 6/QML, MLT, and FFmpeg.

Earlier releases focused on core timeline workflows, title overlays, multi-clip editing, and stronger startup and packaging verification.

This release turns attention to another important part of video editing: the export experience.

Why focus on exports?

An editing workflow doesn't end when the timeline is finished.

Creators often need different kinds of output. Sometimes they want a full-resolution export. Other times, they need a smaller preview to review timing, transitions, and audio before producing a final version.

The objective of v1.2.2 is to make those choices easier while strengthening the checks around the generated MP4.
