[PD] pix_film + incrementing frame number = blurring

Hi list,

I have a patch that syncs multi-channel audio with video by passing
frame numbers to pix_film. These frame numbers are generated by the
audio playback. With HD video however and scenes including smooth
movements, the image becomes a little jittery and a bit blurred. I tried
completely disabling the audio but it made no effect. When audio is
enabled and I run the pix_film with an "auto 1" message, playback is

I'll experiment now to see if lip-sync can be maintained without propper
frame-sync, since my clips have at maximum 3min duration.

I'm wondering though if anyone else had come across this blurring? 

I'm using by the way, a heavily butchered version of Hans-Christoph's
framesync (and an old version of it). However, even if don't use the
framesync patches and pass a frame count generated with metro and a
counter at the correct rate of 30fps - the blurring still happens.

Suggestions most welcome!
