qTool (Quick Tool) is a collection of scripts I wrote for FFmpeg. They can convert videos to h.264 mp4 (and other formats) quickly. Simply drag-and-drop the video file on the script to convert them. You can also convert image seqence to video, resize, and even setup batch process. Take a look at the user manual for more details.
