Hello again,

Well people have been a bit aggressive with me around this post.
First I’m french and my english may lack some nuances to be fully understood. I’m sorry about that.
Second, I might have more technical background than one could think. I’m not going to show references and diplomas, but please don’t say I’m wrong without digging a bit the question…

Having said that,
HDV is very close to blu-ray specs. This is a fact, no controversy possible.
HDV is 1440×1080@50i (for instance) mpeg 2. It meets Blu-ray specs. The difference is that HDV is a transport stream. Is has to be demuxed to be uses in Encore. When demuxing is done you have a m2v file which is 100% BLU RAY COMPLIANT. Please trust me, I did it many times. When imported in Encore, with the correct preset, it is NOT re-encoded before burning. This method is used with many people. It’s not coming out of the blue. And it also work with every HDV flavors. Please try.

Now my question was about demuxing.
And yes I use DVD studio pro to do this which can seem ridiculous.
Here is my workflow :
In DVD studio pro, sart a new HD DVD project. Import your HDV footage as is. Put it in a timeline. Right click in the timeline and choose export as mpeg file. DVD studio pro demuxes the file without re-encoding. I know this is not what DVD studio pro is intended for, but this is a good workaround.
Logically my question was : how to demux HDV without this workaround, I mean with the proper tool. My question was not : is it a correct workflow for blu ray burning.

This workflow should be a good news for people working with HDV and burning blu rays. It does save lot of time an quality.
It is straight out from FCP into Encore without transcoding. Just demuxing.
Please please please, before saying I am wrong. GIVE IT A TRY !

If you’re still suspicious a a look at this thread :

See, I’m not the only one… Be open with new ideas !

Thanks, but that’s not what I am looking for.

HDV is almost blu ray compliant.
It’s 1440×1080@50i mpeg2, which is fully part of blu ray specs. So when working wit HDV material, there is no need to recompress with third part application. I have already made blu rays this way. No recompression means a significant gain of time and quality. The workflow is just to split the HDV stream into 2 elementary streams. These elementary streams are blu ray compliant, straight, which is the best method possible for HDV material.

The little drawback is that process of demuxing (splitting) the streams in HDV is not support by a lot of apps. That’s why I’m looking for some user’s experience.

Thank you
Emmanuel

Sorry, I think I was not clear.

The aim is burning a blu ray without reencoding.
HDV is almost blu ray compliant. The only thing is to be able to demux the HDV stream into 2 elementary streams. Then I can author my blu ray in Encore, without reencoding, which means pristine quality.

My trouble is just about finding the most efficient tool to demux HDV on the mac.

Thanks
Emmanuel

I found a free work around using a demux feature of DVD studio pro.
If someone interested, i will explain…

Hi,

No it won’t work.

This is a well-known issue : HDV captured with FCP is not compatible with PC. This is a codec problem. There is third-party solution to patch this issue, but no simple trick to fix that…

The only solution is to demux the streams and remux them. I can do it, but my method is a bit tricky.

Hello,

No ! original captured clip don’t play…

It would be nice if there was a free workaround…
