I have found it realativly easy to convert a sequence of stills to MPEG1 using TMPGenc.

My question is, how do you do this for MPEG2? This breaks down into almost two separate questions:
1) The frame rate question, ie for PAL the images have to be "served" at 50Hz, how do you "fool" TMPGenc into then interpreting every second field as either a top field or a bottom field and produce a sequence of frames at the correct 25Hz rate
2) the pixel displacement problem, presumably, each image (gif, bmp or jpg) has to be displaced by +/-1 pixel relative to its predecessor. Will TMPGenc synchronise automatically the top/bottom field order.

Has anyone tried this? I'm considering doing this to create an interlaced test pattern to test bench MPEG capture cards, and I'd like to create a SVCD to play on a DVD to source video into the test capture card. I am considering creating the hyperbolic zone plate test pattern using Mathematica or Matlab. At least it would form an independant test source we could all use.

Thnx in advance
