Hi, 0n 07/01/[EMAIL PROTECTED]:30 Evighetens Mørke told me:

As you use --export_prof I suppose it will set a better default, so skip it. -b 128 is IMHO ok for mp3 abr, but it is probably a littel small for layer2, I think the default --export-prof setting (?228?) will be better, skip it, too. There is IMHO no need for -N, -m, -ext, too. Just give -o GOUNA (no extension) and you will receive the same results. Further it could help to use --dv_yuy2_mode as I don't know how your distributor is compiling libdv. In general: When you use --export_prof avoid using other options changing the defauls --export_prof gives. At least scaling/cropping the image will break the reasonable defaults set by profile usage. This is probably true for other options, too. > [filter_tomsmocomp.so] v0.1 (2004-07-31) Tom's MoComp deinterlacing filter > [filter_tomsmocomp.so] topfirst True, searcheffort 11, usestrangebob False By setting --encode_fields b you tell the encoder that the stream will be bottom field first (which is AFAIK true for all dv data) I don't know about Tom's MoComp but deinerlacing the stream and advicing the encoder that it will be feeded with a bff stream, is IMHO somewath strange. I would skip this filter, too. Last not least: You have to make sure that your dv stream is dv2 avi or (prefered) raw-dv. Transcode can neither handle dv1 mode streams nor any proprietary extensions your $BestDVImplementationOnEarth (camera buddled) grabbing software will offer. > Does somebody know how to do this ? and is there anyway to do this > transcode without mplex (like ffmpeg , mencoder) ? No, but if you follow above given hints, mplex will happily mux the streams you received using -f 8. I am not that familiar with ffmpeg. To get a dvd compatible stream from your input I would use: transcode -i oi001.dv --encode_fields b --dv_yuy2_mode \ -y mpeg2enc,mp2enc --export_prof dvd-pal -o GOVNA and mplex it later. As I suppose your original stream is already 4:3, I skipped --encode_asr, too. HTH BTW: I scrolled the manpage of my transcode 1.0.2 a little while writing this. At least in the secton about --export_prof there are still some command lines quoting -V which is IMHO only true for older versions. -- bye maik
