1080i.H264 to MPEG2 or DivX ??

[Big Den]

Have tried all my existing software..... no luck so far. Can play the files OK using codec from PowereDVD 7, but so far none of my encoding stuff works when re-coding!! VDM, GKnot, Videoredo plus etc... anyone got any suggestions??

I am wanting to re-code these massive files (from BBC) to DivX HD to save disk space. Can fo *.ts files OK but not these!!

The file is .ts so how can DirectShow play it? Anyway it does not work.

I would love to know how to import these .ts BBC/ITV HD files into ANY editing software to convert to any other codec.

Thanks.

[Big Den]

So would I. It IS possible as I have got a copy of an Xvid re-code of Planet Earth.... it has the BBC-HD logo in the left hand corner!! Coded at 960 x 528.

Anyone else help with this... ???

Had same problem with MS files *.dvr-ms when they fisrt arrived on the scene :)

[Leica]

Well if someone has done it, then obviously there is a way. Please someone for the love of God, help us!!!

Perhaps a way to demux the TS stream and then maybe x264 can decode it???

Help!!!

Hi,
You have mentionned Mpeg2 or Divx. I cannot help you with divx but there is a trial of a commercial program that accept Mpeg4 and/or HD-TS files, you may want to give it a try.

It is ConvertXtoDVD page here: http://www.vso-software.fr/products/convert_x_to_dvd/convert_x_to_dvd.php?lang=en

Edited: there may be a Divx (6.1 only, 6.22 and after have problems) solution with Autogk with TS files as sources. But if you read threads related, Some TS files can be feeded in AGK others cannot ...

Cheers Big D ..... checked the specs, does not mention H264 in the list.

I guess we continue to search :)

From what I understand VSO's ConvertXtoDVD is able to re-encode "Main Profile" MPEG-4 AVC to MPEG-2/DVD .VOB.... but not "High Profile" MPEG-4 AVC.

This was certainly the case with it's fore-runner ie: DivXtoDVD ;)

Big Den , Are you talking about this samples?

I'm moving this thread to the HDTV / DVB / TiVo forum, which is more appropriate.

Using the VLC-player ( http://www.videolan.org/vlc/download-windows.html ) I was able to convert a AVC/H.264 to a different video format. The VLC has a transcoding option for readable video files and streams. If you click on File and then Wizard and then enable the transcode option then you are able to transcode HDTV-videos to different format resizing them or just recoding them to a different format.

[SeeMoreDigital]

As far as I'm aware, not even the new beta versions VLC player can correctly handle high-profile MBAFF and PAFF interlaced AVC sources as used by the BBC (and other European HDTV distributors).

The HDTV-clip I was able to transcode were clips transmitted by the new DVB-S2 system from ASTRA PRO7-HD and taken from the following link:
http://www.dvbmagic.de/download.php?nav=Download-Center&category=HDTV-Clips

[SeeMoreDigital]

Indeed... these clips should work okay with VLC player. But the BBC ones don't ;)

[Eeknay]

DirectShowSource + CoreAVC 1.1 + latest Haali splitter works just fine. Trust me. Done it many times with my own material.

You don't even need CoreAVC, actually. You can do it with Elecard's h264 decoder (the trial version will put some blocks in the corner of the image though) and CyberLinks (PowerDVD7). They both support MBAFF.

As for VLC vs BBC clips... the new betas do work, but they're kinda buggy. You can transcode to MPEG2 with VLC just fine. Although DSS() is probably more flexible.

[Schmendrick]

If you install the trial version of PowerDVD7 the installed directshow decoders can be used with Avisynth and you can make conversions without "some blocks in the corner". I just have tried it myself. The AVS-script loads just fine into e.g. VirtualDub.

[Pookie]

Can Mplayer play it ? If so, perhaps Mencoder can convert it.

edit: Yup, just tried that BBC h264 TS example file. Looks like Mencoder can convert it. If you want to make it very easy, get this basic mencoder front-end (Not dissing MEGUI, btw)

http://users.bigpond.net.au/nexx1/dvbmenc/dvbmenc_beta0.1i.zip

I used a June 2006 version of Mencoder.

Otherwise, this batch file ought to do the job, but you'll want to play with the settings to optimize it to your liking/functionality.

I'm trying to convert the BBC samples to mpeg2 .ts although using a avs script i can convert the video i cannot for some reason get the audio out of the .ts to mux back with the video

has anyone found a good way of converting these streams yet?

Have you tried the methods described in http://forum.doom9.org/showthread.php?t=110312

[chrisc0le]

I have now, i found that thread after posting.. dont think the audio in in sync when i mux back together though. spose thats to be expected and then i'll need to guess how far out plus or minus it is.. mind you i'm using womble mpeg wizard to mux back together as elecard xmuxer wont do anything when i add an ac3 audio track.

[kelman3]

Try MPEG Streamclip (http://www.squared5.com/). I haven't been able to use all it's features but it seems pretty loaded for all kinds of encoding.

[Big Den]

Thanks for the info... reply from Squared 5 re mpeg streamclip:

"Not yet. For sure, a future version will be able to play H264
streams; maybe, another future version will also let you convert them to MPEG2."

Sorry for the bump, but VLC has a 'freehd' strand (basically patched 0.8.5 to decode MBAFF files, originally done to play files ripped from the french 'Freebox' system but which will handle any MBAFF-encoded files fine), which can play back at least some BBC HD content, the files I've tried anyway.

I just tried out the BBC_H264_test6.ts sample which has been floating around the web for a while, and it did play - but VERY jerkily (and the sound came in about half the way through the file... But I do only have a 1.8ghz Sempron).

Try it for yourself (NB: BETA code, obviously not optimised):

http://download.videolan.org/pub/testing/freehd/ (Win32 and Mactel compiles there, plus sourcecode).


I can play back other .ts files fine in WMP9 with the hdtvpump plugin from dvbportal.de, but it doesn't play back the video on that BBC_H264_test6 file, just the audio... But it's evidence that .ts files can be push demuxed through DirectShow... Therefore it must be possible to use it to latch onto a transport stream to decode it (and take that data to transcode).
