Looks good Valentino!
In the beginning when you said you did not select timings, the 25,50,100 selection is for the base timing that the effects are generated with. The sequence timing is different from timing tracks. Since you did not pick one, it defaulted to 50ms and you can see those as the grey lines on the sequencer window. Also if you haven't tried this, make a tree that is bigger than the sequence. Make it 20 strands and change the X value when you select the tree. All of the converted effects will look good and the images that don't move will stick to the original X values.
Peace,
Steve
