[M4IF Technotes] quick time

[Kumar, Gautam]

Hi,
   I am new to quicktime format.We are trying to
develop a software that will convert the h263
bitstream that our encoder produces to qt format so
that qt players can play it.The present software that
we have converts it to qt alright, but the image gets
distorted when we try to drag the cursor at the bottom
of the qt player.However I have seen qt films produced
by Adobe Premire(I+P they claim),which does not get
distorted even if we drag the cursor backward.How is
this possible using qt file format.
It will be great if someone can tell me how.All ideas
and suggestions are welcome.
Thanking you in advance.
Regards
Gautam
