Which problems are you facing (e.g. corrupt output, plugin > intialization error...) > Thanks for the reply.. We have narrowed down the issue: A 24bit PNG now works, but it only works with either fully transparent or fully opaque pixels in the PNG image, if we have a logo that is (say) 50% transparent (we have a watermark logo that is transparent by 50% with a drop shadow on it as well), then transcode adds the image, but it is entiry blank. Is this a limitation with transcode? here is the output from our transcode command: # transcode -i preview.m4v -o preview_out6.m4v -y ffmpeg -F mpeg4 -J logo=file=watermark-24bit-gimp.png transcode v1.0.7 (C) 2001-2003 Thomas Oestreich, 2003-2004 T.
