I think it is very bad strategy, coz u loose quality. Better way is to
add to kdenlive 16:9 profile which will apply on all Text Clips and
As usual, 16:9 video is captured by standard camera with 16:9 function
inside or 16:9 lense. So we always get 4:3 video and we have to work
with it, and export it without resizing. Just set needed option when you
burn your DVD disk. But in the case of internet video, just do resize on
final step of processing your video.
