How do I render and save as MP4? I am using the latest version of 2.78a and I can't figure out how to save it as an MP4 file. I have downloaded an intro template (for youtube) and changed the text to what I want, but I don't know how to save it as an MP4 file. I have rendered the animation on default settings and it keeps rendering the animation over and over again. What do I do?
Blender will render the frames that are between the start frame and end frame if you press Animation.

The outputfile is located in the path that is shown in the text-box. You can change it pressing the button with the folder icon

You can either the animation as an image-file sequence or as a video file. MPEG will output .dvd format, but you can change the extension to .mp4 in the windows explorer (you must check the option to view the file extension in folder options from windows
