As the title of this application may suggest, it's a simple way to launch the x264/x265 encoder to quickly and easily use the HEVC encoder on support video files.

Simple x264/x265 Launcher uses the 64-bit version of Avisynth and Vapoursynth to convert from the following video formats: YUV, MKV, MP4, VPY, AVI, FLV and a couple of others.

The main interface isn't anything to write home about, but it's easy to get around in and can create tasks with ease. It can start, pause or abort a list of tasks and as such, can effectively do batch conversions.

Simple x264/x265 Launcher comes with a few different presets and can apply effects to video files such as film, animation, grain and still image. Profiles include main, high and baseline. You can also save presets.

Although it might seem primitive, Simple x264/x265 Launcher is a really easy way to use x264 and x265 encoding.
