 You can leave the audio part to Copy (with MP3 audio file), that way you avoid unneeded encoding step which will save some time and keep the audio quality.

 Saving the video happens via **File -> Save -> Save video...** (remember to give file extension, e.g. if you selected Format: MP4, then add .mp4 to filename)

 This is the hardest part of the operation. Fortunately you don't have to study AVIsynth scripting, since the code sections give below will work for most scenarios and hopefully you will notice the patterns that you can use if you want to do some modifications.
+If you want one image and audio track for that, you use [[http://avisynth.org/mediawiki/ImageSource|ImageSource]] + [[http://avisynth.org/mediawiki/DirectShowSource|DirectShowSource]] + [[http://avisynth.org/mediawiki/AudioDub|AudioDub]].
+For Imagesource you define the image file (inside ""), and how many frames you want (end=), and the FPS (fps=). For DirectShowSource you set the audio file name, and force it to audio only mode. AudioDub just joins (muxes) the video and the audio together.
+For example, following script would use ie_logo.png as still image input (1500/25=60 so duration is 60 seconds), and teaser.mp3 for audio
+<code>
+V=ImageSource("C:\softa\avidemux_r7389\ie_logo.png", end = 1500, fps = 25).ConvertToYV12()
+A=DirectShowSource("C:\softa\avidemux_r7389\teaser.mp3", video=False)
+AudioDub(V, A)

+You shouldn't leave the audio or the video part to Copy since AVIsynth passes forward only uncompressed audio and video (output file size will be huge with uncompressed raw video).
+//(you can apply filters at this point if you need them via Video -> Filters or Audio -> Filters)//
