DV to VCD / audio question

[zulu]

Hi forum,
i've got the following situation:
recently i bought a digi cam (canon ixus 40) that is also capable of recording video. video is saved to an avi file using mjpeg compression @ 320x240 / 30 fps / progressive.

Now, i thought it would be nice to have a vcd filled with clips shot with the cam.
To meet the VCD standard specs, i decided to use the following destination format i want to convert to:
352x240 (NTSC) / 29.97 fps / progressive.
To achieve this, i wrote the following avs script to feed TMPG with:

avisource("cam_video_320x240.avi")
crop(0,12,320,218)
LanczosResize(352,240)
AssumeFPS(29.97)
ConvertToYUY2() # tmpeg doesnt like yv12 input?

so far, so good (..i think. please correct me if something's wrong, im a bloody n00b when it comes to vcd )

what i'm still unsure about is the audio part:
i demuxed an 8 bit 11khz mono wav from the source avi.
what should i do with it to stay vcd compilant?
does vcd allow mp2 audio at this resolution, or am i forced to use 16bit 44khz?
and since i changed the framerate of the video, i assume this has to be taken into account for audio conversion, too.

i thought about doing something like this:

BeSweet -core( -input "demuxed_cam_audio.wav" -output "vcd_audio.mp2" -ota(-r 30000 29970) -2lame( -e -b 192 -m m )

any suggestions? do i need resampling to 16 bit as well?

Thanks for helping me out

regards,
zulu

AFAIK TMPGEnc needs RGB source, so you might need to replace ConvertToYUY2() with ConvertToRGB(interlaced=true).
