Hope someone can give a lead being overwhelmed with the converters available

goal : converting multiple clips from DV to mp4 (joblist/batch ?) with each clip having specific data dislayed on it (like a avisynth's subtitle()) (not subtitles from a textfile !)

Because some of the data is related to certain frames a preview and framesearch is needed. when all clips have their appropriate data specified then batch convert all the projects in one go (lets say each clip would need a different persons name displayed on it )

for individual clips I had no problems with staxrip : preview the clip search for the frame numbers I want and add that to the avisynth filter caling a function.
but I am haivng to much problems trying to automate/batch

been looking into avidemux wich is even better in making me search for the appropriate framesnumbers I need but am struggling wiht getting the same filters/functions i was using in staxrip to work . Struggling wiht how to set them up and be editable at the same time ( specific text) .

Any other prgrams or scenarios I might consider ? talking short clips but lots of them

thanks
