As it's really important to put a frame counter on your Wip animation, here is how to do it!
First you have to download a script!
you can find some here.
Some will just work on the playblast of maya, other both in the batchrender and the playblast.

http://www.highend3d.com/maya/downloads/mel_scripts/feedback/frameRender-4224.htmlit didn't work at first so I modified it a bit and now I love it. it's really like an object polygon so you can see it in the playblast or the batchrender. you can also hide it or delete it like a normal object.
if it doesn't work you can contact me by pm
to use a script, open your script editor, File / Source Script / and select the script.
then the script is load in maya, to activate it often you will also need the command that is usually given at the beginning of the script or in a txt file attached with the script. (you can open a script file with the notebook) then in the command line of maya (or in the script Edito) type that command and the script will run.
for the last link a sent you the command is
frameRender;
hope it was usefull!
