Help converting BBC HD TS to SD DVD

SimonKilmore

Hi Guys,

I hope i'm posting this in the correct place, seems the most relevant.

Firstly i'll just say i have no problem converting 99% of Transport Streams to SD-DVD. I know of all the required programs and settings, so i'm not new when it comes to this.

However, i have just grabbed off Usenet a TS which was recorded from the BBC (UK) HD stream.

It is a H.264 1080i stream, in a TS container. Now i have had a good look on google and found several programs/solutions on how to encode these streams. However, after several hours and program upon program, i cannot get anything to work. Here is what i have managed -

- demuxed to .mpv and .ac3 files.

Now this worked eventually using a program called xport, but from here is where my problems start.

I cannot find a MPEG-2 Encoder that will load this file, let alone re-encode it.

Cinema Craft Encoder either doesn't load it at all, or if i load it with a AviSynth Script it crashes. The same goes for any other program. They crash (stop responding) when i try to add the file.

I have had both the CoreAVC codec and ffdshow codec installed, and it hasn't worked with either.

From further research i have also found that the BBC HD stream uses MBAFF Interlacing, which is maybe causing a problem?


My PC:
XP SP 2
Intel Celeron D 2.8 Ghz
1.18GB Ram
Not sure on Video card, but it's one that came in my PC, bought 1 1/2 years ago.

So does anyone know of a way to do this?

Thanks

SimonKilmore

Anyone?

Have you tried the latest version of ffmpeg?

Right i've just got ffmpeg, but i don't know what i'm doing with it?

I've ran it and looked at various input syntax, but i've no idea what i'll be needing to put in to get what i want.

Anyone know of a script i can put into it?

Basically i have the input source PAL 1920 , and i want to output it to a DVD complient MPEG-2 with Constant Bitrate 8mbps, resized to PAL DVD 720x576.

Thanks

SimonKilmore

This is what my current input looks like, but it's not working, so something can't be right.

ffmpeg -i input.ts -aspect 16:9 -f m2v -s 720x576 -b 67108864 -an video.m2v

I used this docmentation to get this -

ffmpeg.mplayerhq.hu/ffmpeg-doc.html

Thanks

It's worth trying default setting till it works then changing what you need.

Syntax is far enough away from the mencoder stuff I use in Linux that I'm not much direct help. This is a useful resource I hope:

Bump. Still having problems with this one.

When you say its not working, what do you mean?
Here's the batch file line I use to go from .tp or .ts to .mpg. Its based on what HDTV2DVD uses. NOTE: some of the lines have wrapped. You'll have to modify the path to your copy of ffmpeg.exe.

::batch process MPG from TP

::Parameters - all parameters must be enclosed in quotes
:: %1=full path to .TP file
:: %2=full path to .MPG file for output
:: %3=desired average bit rate (defaults to 3000)
:: %4=desired max bit rate (defaults to 7800)
::Examples:
:: call hdtompg.bat "d:\dvr\bones\28 - The Girl in Suite 2103.tp" "C:\dvr\bones\28 - The Girl in Suite 2103.mpg" "3000" "7800"
:: call hdtompg.bat "d:\dvr\smallville\128 - Progeny.tp" "d:\dvr\smallville\128 - Progeny.mpg" "" ""

Nice. Ugly place to script ... well done. You are bringing back memories from long ago .

Linux is very friendly to all kinds of command line stuff, you might enjoy the difference.

Come mschupp ...leave the dark side. The force is strong in you ... come to the light. Leave the windose wasteland to the poor unfortunate hungry ghosts who are forced to dwell there.

Now lets not start that!

I make my meager living writing software for Windows-based systems.
