Need tips on video grabs postprocessing !

Hi Eric and all of you,

I need a solution for some videograbs postprocessing...
considering the tools i've got so far (adjust, denoise, dejpeg), what would be the best way to get the best out of video grabs ? I thought dejpeg would be the right choice but i'm not satisfied with the results i get so far using presets. Please note that i am deinterlacing prior to anything else.

Thank you Topaz team :o)
