Anthony, no that warning is fine and expected as encoder_args is defined in a separate file (config.pl). Sounds like the encode step is working as there were no fatal errors. Could be you are missing a decoder to play it back on your PC? Are you using ffmpeg or mencoder for encoding? You can post here the entire command used for the encode - it is printed to the text area of kmttg when that step is performed. I can run using same options on a small clip to check if it works OK. P.S. Next version I will make it possible to make text area text selectable so that copy/paste works (it already works in Linux as is but not Windows).
