Ron, That's good to hear.
My big question, still outstanding, is: "HOW do we control the size/rate of those .mpgs?" I believe that neither dvdauthor or dvdstyler will add much overhead, nor should they make the .mpgs any more compact. But, when rendering in Cinelerra, and when combining in ffmpeg, the only parameter that seems to bear upon size and bit-rate would be the -target option. Do you use something different from '-target ntsc-dvd' ?? (BTW: For Cinelerra rendering, I use the ffmpeg pipe: "ffmpeg -f yuv4mpegpipe -i - -y -target dvd -flags +ilme+ildct %") Unless you (somebody) have applicable experience, I guess I'll just futz with the ffmpeg parameters to see what happens. Thanks again. On 2009-03-02 19:20, Ron Sparks wrote: > On Sunday 22 February 2009 03:02:34 pm John Detwiler wrote: > > 2.
