[Mp4-tech] Compression ratio

[Gopalakrishnan Srinivasan]

Hi Experts,
               When we do system analysis for MPEG-4 simple profile at simple level what is the compression ratio as rule of thump we need to consider for each I & P frames. I need this info to do system analysis for fast forward & fast backward so that how much % of overhead we need for inserting more I frames.
Thanks & Regards,
SGK
