  Images are especially bad when there is camera movement.
  I mean really bac,—-flickering and strobing!

  I bet, you messed up field order.

  Yes, field order.

  Right click on media on the timeline.
  Prpoerties; media tab.
  There you can see field order.
  DV files are usually lower field first.

  Other sources (analog capture devices) may give you
  upper field first video, that depends on the capture
  hardware.

  No problem with either, BUT

  When you render, the source media
  field order must be consistent with the
  target.
  So, when you render from lower field first DV AVI
  into mpeg2 for dvd, the field order should be set
  to “bottom field first” (render as… / custom /
  video tab / field order)

  If the field order settings are not consistent
  moving gets jerky, eye-hurting.
  This was the first lesson I learned when I started
  with video digitizing and editing. 😉

  You can also convert upper field first to
  lower field first (or vice versa) using pan-crop.
  Assuming PAL video
  With :720
  Height: 576
  XCenter: 360
  YCenter: 281 <--(!!!!) Don't maintain aspect, and don't stretch. (!!!) By(t)e Laca

  [Laszlo Kovacs] “YCenter: 281 <--(!!!!)"

  Ooops.
  I copied these values from a set which also removes those
  distorted lines from the bottom of VHS records.

  If you need convert only, YCenter should be 287.
