Like Aura Video Editor, VideoProc is more than a simple subtitle editor. This full video editing package is hardware accelerated so you can take advantage of your GPU for smooth editing of video files up to 4K resolution. Unlike other software on the list, VideoProc is not free software. You can get a free trial, though, so that you can see if VideoProc is worth the price before you have to spend any money. The software is available for Windows and Mac computers.
