What's New in r427
Release r427 was published on 17 Feb, 2025
Normally we release beta updates on a Tuesday, but this week we've brought the beta release a day forward. The reason for that is a change to spritesheeting in the previous beta caused a crash opening some projects, and we wanted to get the fix for that out sooner.
In this release we've added support for the H.265 video codec with the MP4 container when exporting videos! This is subject to browser/platform support, but is now supported in Chromium-based browsers like Chrome and Edge. We've also extended H.265 support to the Video Recorder object (which handles real-time encoding), which is also subject to browser support - that's expected to come to Chrome and Edge soon.
Another key change in this release is when exporting a video with the H.264 codec, previously Construct Animate did not pass the intended video framerate to the video encoder. This was to work around a bug in Chrome which did not handle the framerate correctly with H.264. The bug was since fixed and now the correct framerate is specified. However this may affect the calculated bitrate and resulting file size - so you may want to check the video quality is still appropriate if continuing to use existing settings for a H.264 export.
There's a range of other additions in this release including for the CPU profiler, flowcharts, and TypeScript support, as well as a performance improvement for Mouse and Touch object conditions, and as ever a batch of bug fixes (including for the regression from the previous release). Happy testing!
