Hi Chang,

[Chang Dek] “VTS files into iDVD but it didnt
like them, and I converted them to Qtime files
using MPEG Streamclip which made them into huge files. “

You don’t need to convert the VTS in QT movies. Just “Demux to M2V..”
You will extract the MPG2 and audio file without loose at all. Just bring those files to DVDSTP (guess iDVD will like them too but I have never use it).
However, YOU CAN NOT PUT TOGETHER NTSC AND PAL MPG2s in the same DVD.
A DVD must be full PAL or full NTSC.

Thanks AK, what is optical flow? I dont see that as a setting in Compressor.
Will iDVD do all the NTSC to PAL conversions without having to convert in Compressor?

Thanks Rafael, which program does the “demux” ? Chang

[Rafael Amador]

MPGStreamclip.
File Menu> Demux to M2v and..
Choose the same kind of audio as in the .VOBs.
The audio and video are simply separated in two different files. There is not any kind of recompression at all.
If you have any problem just post again.

Thanks again Rafael, are the m2v files editable in FCP 5,1 ?
Do the demuxed m2v files retain their original standard (NTSC /PAL) ?

[Chang Dek] “re the m2v files editable in FCP 5,1?”You can not edit MPG2 files in FC. MPG2 is a format difficult to edit because is not made of individual pictures, but groups of pictures.
I think your best option is to use MPGStreamclip to convert the MPG2 that you want to edit, as QT movies.
Export your QT movies using a good codec (at least DV50, 8b Unc better) to keep the most from the MPG2. Set all the parameters matching an Easy preset of FC, so you won’t need to renderthe clips in the FC sequence.
NEVER “Export to DV” because you won’t get a QT movie, but a DV Stream (as the used by iMovie)
I think that this is the best workflow for the files that you have to convert PAL_NTSC.
You can do it with Compressor or in FC using the Nattress Sttandar Conversor. I heard that MPGStreamclip (That application is wonderful) makes a goo standard conversion too.

When you are Demuxing, you are just splitting the video and audio in two different files, but the two files keeps the same atributes that when they were muxed. You will see that the process is quite fast because in fact is just to write the same information in two different files.

Hi Chang,
I’ve read in your profile that you are in Thailand. Great, I’m in Vientiane, not too far.
In which town are you based?. Normally I go few times a year to Krung-Thep.
Perhaps we can meet some time.

No, and at some point you have to convert formats.

Standards Conversion With Frame Controls in Compressor 2

With the Frame Controls feature, you can convert video files between international television standards (such as PAL to NTSC or NTSC to PAL) at levels of quality that were previously only available through expensive hardware solutions.

To convert a file, add the source media file to the Batch window.
Open the Settings tab of the Presets window and find the appropriate target setting or create a custom setting.
( The Advanced Format Conversions settings group contains many common
settings for international television standards (such as DV NTSC or DVCPRO50 PAL).
Apply the setting to the source media file in the Batch window.
Click the Frame Controls tab in the Inspector.
Choose Custom from the Frame Controls pop-up menu.
Choosing Custom allows you to manually adjust all of the attributes in the Frame Controls pane.
Make changes to any of the controls in the Frame Controls pane. (See
