Capture DVB-S in Xvid

[AllstarElyar]

is there a way to cap DVB-S in Xvid or Divx,cuase i dont want to encode it again.
or a program which cap analog tv in xvid or divx format?

thx

DVB-S is MPEG-2 (I heard some europeans use MPEG-4 too).
If you want to preserve original quality you either keep it as is, or author it to DVD-Video.

If you want it as mpeg-4 using specific codec (xvid) you have to find capturing software able to convert transport mpeg-2 to mpeg-4 with your codec on the fly (that means it must cooperate with your dvb computer card), or maybe your card is capable of outputting 'recordings' in different formats? Some cards are, but what they actually do is they dump the original stream on your hard disk, and reencode it to format you chose 9which is actually stupid IMHO, since you can do it yourself too, and with better results).


Unless you want to 'record' from a standalone DVB receiver through its analog outputs - then just search for any standard old plain analog capture card. Majority of them are able to capture in AVI with almost any codec of your choice. Just be aware, that capturing in highly compressed AVI (xvid) is possible only on a newer (faster) computer, if you have something old like AMD Athlon or Pentium 3 its doubtful they'll be able to do on-the-fly encoding fast enough.
And lets not forget that you will be cranking out 1-pass encodes, which will not be as good as 2-pass encodes not made on-the-fly (unless you use much higher bitrate than you would at 2-pass encoding, cranking out much bigger files - but then why use xvid, keep original MPEG-2 dumped stream rather...)

thx but i really need a tool that record dvb-s(mpeg-2) in xvid format.
becuase i dont want to waste time encode the mpeg again
anyone knows a program?

You would be capturing the MPEG-2 TS though, not encoding it, so there is no "again". Encoding after capturing means that you can use higher quality settings than for real time encoding.

i say xvid that mean just xvid not mpeg-2

so please help me with finding a program that i want

Have you looked through the list in the tools section ? - https://www.videohelp.com/tools?s=5#5

It seems to bear out what you are being told here - the software you want most likely does not exist. There is no point being rude because you don't get an answer you like. You have also been given the reason no-one has bothered - because the quality would be too low capturing form the mpeg2 stream and converting to Xvid in realtime. And even if a program like this did exist, you cannot escape the fact that you are re-encoding. The stream has already been encoded to mpeg2. That is what you receive. Your concern is preserving quality. The only way to do that is a multi-pass Xvid encode, which requires you have the stream on your HDD. A single pass encode - the only way to do it on the fly - would require such as high bitrate as to negate most savings.

MythTV can I believe capture with libavcodec's MPEG-4. Not XviD and wrong OS. Still as close as I can think of. But then I don't have a DVB card. Anything windows based I would imagine if it can encode on the fly would simply make use of installed VfW codecs or dshow encoders.
