[Mp4-tech] performance comparison between open loop and closed loop motion estimation

[Gary Sullivan]

Tae Meon Bae,
What do you mean by open loop motion estimation?
Best Regards,
Gary Sullivan

Dear experts,
I'm optimizing h.264 encoder, and I have a question about motion estimation.
Generally open loop motion estimation shows lower performance than closed motion estimation. Is there any JVT document or paper related with this issue? I guess that the performance gap may be small if the target bit rate is high enough. Is this assumption right?
Thanks in advance.
Sincerely,
Tae Meon Bae
