When you render something, Blender will automatically append the frame number to all output files' names, producing filenames something like render_0001.png, render_0002.png, render_0003.png, etc.

For frames of an animation this is great, since it keeps the same file from being overwritten for each frame. But for videos this is usually unnecessary. Is there a way to keep Blender from adding the frame number to every render output file?

Do you mean that blender adds the frame range to file name, say test0001-0025.mp4? Or does it save multiple files? – maegmaeg Jan 31 at 22:19
@maegmaeg For your example, I just want it to output test.mp4 and not concatenate the frame range to the end of the name. – PGmath Jan 31 at 22:20

Simply put test.mp4 as the ouput not just test without the file extension.

this is working with VSE but not with rendering an animation. At least it did not work for me with avi. It ignores test.avi and creates test_avi0001-0050.avi – maegmaeg Jan 31 at 23:10
Argh my fault. I used an underscore and no period. You are right! – maegmaeg Jan 31 at 23:11

Specify the full filename and disable file extensions. Adding file extensions includes adding the frame number to the filename.

EDIT: As @ferhoyo points correctly out, you just have to add the file extension, say test.mp4 or test.avi.

I don't think it is possible. In the official documentation it says:

When rendering an animation, the frame number is appended at the end of the file name with 4 padded zeros (e.g. image0001.png). You can set a custom padding size by adding the appropriate number of # at the end of the file name (e.g. image_##.png would translate to image_01.png).

Probably you can shorten the output with test# to say test01-25.mp4

Why do you save to a movie format at all? An image sequence has so many advantages...

As for why I save to a movie format: 1. even if you save to an image sequence first when rendering animations (which I do), you then combine it in the VSE and output as a movie, and 2. I often use the VSE for general video editing stuff in which case I need to output a movie file. – PGmath Jan 31 at 22:33
Ah, it happens with VSE too... As i wrote above i don't think it is possible to change. – maegmaeg Jan 31 at 22:41
