Dvtodvd.Sh

This script can be used to convert raw DV video (such as from a camcorder) to VOB files suitable for recording to DVD. Multiplexing is performed by the mplex program from [mjpegtools].

 DENOISER=yuvdenoise  # best quality, but SLOW
#DENOISER=hqdn3d      # faster
#DENOISER=denoise3d   # even faster, but quality suffers
