Frameaccess.java - time of presentation of each frame

Question

i've found frameaccess, which introduces a plugin in transcoding phase of processing.my question are, (i'm a newbie of jmf) it's possibile to modify in the code below the processor to have in shell display,time of presentation of each frame?another question is :it's possible to modify framerate and bit x pixel of output?
thanks

It's difficult to compare these apps. They have differences in capability - some are driven off templates. some aren't. Some have a wider variety of transitions. Others will have excellent audio controls. It's worth checking them out to see what meets your needs. However, there is no doubt that Final Cut Pro X is the most capable app of them all. You get what you pay for.
