if you are experienced stutters at video playback
first make a test-recording:

  1. set Settings>Video>Base (Canvas) Resolution: 1280x720
  2. set Settings>Video>Output (Scaled) Resolution: 1280x720
  3. set Common FPS Values = 30
  4. uncheck Rescale Output if any (Settings>Output>Output mode: Advanced>Recording tab>Rescale Output).
  5. create empty scene
  6. add Image source and select the image (see the attachment)
  7. add Scroll filter to Image source
  8. set Scroll filter parameter Horizontal Speed to 100 (the image begins to move)
  9. right-click on Image source and select Transform>Center to screen (Ctrl+D)
  10. click Start recording
  11. wait 20 seconds
  12. click Stop recording

check recorded file with your favorite media player

Now look at recorded video - does is stutters?

try another media player (if you have enough skills to open video file frame by frame - do it!).

My player shows stuttering. But another one goes smooth. It has stutters at first run, but if I rewind the video by 2-5 sec stuttering in that place disappear. Magic. The recorded video opened by virtualdub (DShowInputDriver + ffdshow + haali), avisynth + megui, any other software frame by frame, and it shows perfect image sequence without significant 'jumps'.
