I'm having trouble saving a .png slideshow as a .mp4

[pendylion]

Hello!
I'm running a windows xp, home edition- hence the need for avidemux.

The scenario:
I have a series of .png files, named appropriately. I want to turn them into a series of animations, to then be appended together into one entire sequence.

Steps taken thus far:

Attempting to animate the first sequence I-

• Opened the first .png in the sequence. The rest of the .png files in the sequence are automatically appended.
• Saved the sequence-
  
  
  
  • Video output >Mpeg4 APS(ff)
  • Audio output > copy (note: there is no audio)
  • Output Format> AVI Mux> AVI
  • Save As> test.

Problem
The sequence cannot be opened by quicktime.

Notes

• Googling, there were many suggestions to use Video output >Mpeg4...(x256)(?).
  
  • Trying this configuration I would always get a "bitrate too low" error and I could never save the file.
  • By another suggestion, I did  complete uninstall (revo uninstall) and reinstall from here: http://avidemux.org/nightly/win32/
• There was another suggestion to go to Video drop down menu to change the frame rate, but there is no option for that.

Thanks!
