Lower resolution or "red" bitrate?

[RastaPiggy]

I want to fit a movie of 115 minutes on 1 VCD (dont ask :P) but with the normal presets ffmpegX gives a red bitrate. lowering the sound to 128 bitrate still keeps in the red. So if I lower the resolution a little bit, I am able to get it in the green zone but does this improve the quality on my tv compared the the red bitrate but larger resolution mpeg?

A VCD can only use standard image size for playback on a DVD player. However if your source is a NTSC VOB, probably setting framerate to NTSC FILM will reduce enough the number of images per second to almost go again to a green bitrate. Also if your DVD player accepts non standard VCD in VBR mode, you can disable constant bitrate encoding and use a higher bitrate - the final size will probably be lower than the calculator forecast.
