Convert m4v to txw

What is the difference between .m4v and .txw?

Description: The M4V file format is a video container format developed by Apple and is very similar to the MP4 format, with the primary difference being the optional Apple Digital Rights Management (DRM) protection. M4V files are commonly used for TV episodes, movies, and music videos in the iTunes Store. These files can be played on Apple devices such as iPhones, iPads, and iPods, as well as on PCs using iTunes or other compatible media players.; The TXW file format is associated with the Yamaha TX16W, a digital sampling keyboard produced in the late 1980s. These TXW files contain audio data that is specifically formatted for use with the TX16W sampler. Essentially, a TXW file stores a sample or a collection of samples, including their associated parameters such as loop points, velocity layers, and other settings that are necessary for the sampler to correctly playback the sounds. The format is proprietary to Yamaha.
