I have released rav1e GUI v1.3:
This new version adds the new min-keyframe argument to the GUI as well as making the existing keyframe be the max keyframe interval. This means you can now specify a number of frames to be the minimum and maximum keyframe interval and rav1e will make keyframes according to these specified numbers. If you’d like to just use a single keyframe interval, you can specify the same number in the minimum and maximum value boxes.
Another change is that you can now save your video using the Matroska container. This is in addition to the WebM container. Lastly, I renamed piece to part in the GUI, which is used to specify the length of each video part when splitting the video to accelerate encoding.
As usual, this release includes the latest version of rav1e as well as the latest version of opusenc.
