Often on projects which contain long clips or many clips, the performance of our keyframe system would slow down. Keyframe performance improvements (magnitudes faster) A huge thanks to Peter M for his dedication and help with this one! This can increase performance by up to 30-40%, just depending on all the various factors. For example, if you are using only MP4/H.264 input files, and your graphics card is supported, it can help OpenShot decode the pixel data from the video, and on the flip side, encode the pixel data back into a video. This can result in a huge performance improvement on some systems, but also depends on the input and output formats, and many other factors.

Many graphics cards come with the ability to encode and decode video data without using the CPU. You will see some new options available if you have a supported encoder/decoder. Perhaps one of the most exciting changes in OpenShot 2.5.0 is our experimental support for hardware acceleration. Let’s start with the highlights! Hardware encoding and decoding support
