Positioning works fine (I wonder whether -P should be the default option 
for swfextract), but my issue with fast transitions doesn't have to do 
with fps, but with the way the slides are extracted.

Let me explain the issue in a better way (sorry for not having done this 
before). I'm interested in converting PDF slides into a Flash file to 
add sound synced with the slides (the recorded voice comment the slides 
[which is also the standard way to give a presentation]). I have already 
achieved this thanks to your excellent SWFTools (many thanks for this).

In some cases, it might be that the original PDF slides are missing. My 
point here is not modifying the transition rate in the slides, since 
they are set in fps and this rate will always be constant, but to 
rewrite a whole new sync between audio and slides. Of course, this is 
much easier having the original PDF slides, but sometimes it the only 
way to achieve it would be to use the SWF slides (converted by pdf2swf 
and included in the final Flash presentation synced with audio).

The issue with the extraction is that the SWF slides 
(http://ousia.justfree.com/final-test-slides.swf) are included as 20 
frames and they are extracted form the final presentation as a movieClip 
that contains 20 frames (http://ousia.justfree.com/output-slides.swf). 
The SWF file itself includes only a movieClip, so it contains a frame.

The only way to make extracted SWF slides reusable would be to avoid the 
extraction as movieclip and to extract the slides as a SWF file with so 
many frames as the number of slides it contains. Would this be possible?

Thanks for your help,


Pablo
