I would suggest that the dynamic text filter is cleaner than the data_show filter for what you are doing. Try playing with this: melt -verbose -profile dv_ntsc -audio-track -producer noise out=30 -video-track -producer color:red out=30 -attach dynamictext:'some_random_text' geometry=0,50%:100%x100% color:blue out=30 -filter dynamictext:#frame# Also, if you are testing lipsync, have you looked at the blipflash producer and consumer? The producer generates a synchrinized blip and flash pattern. And the consumer can calculate the lip sync offset given that pattern as an input: melt -silent -profile dv_ntsc blipflash out=200 -consumer libdv:temp.dv terminate_on_pause=1 melt -silent -profile dv_ntsc libdv:temp.dv -consumer blipflash terminate_on_pause=1 ~Brian ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite It's a free troubleshooting tool designed for production Get down to code-level detail for bottlenecks, with <2% overhead.
