demuxing HDV files captured with FCP (for blu-ray)

I said H.262/MPEG 2 not H.264

He wasnt asking, he was stating this was his workflow and I was pointing him in the right direction 🙂 Sorry if I came off like an A hole

Sorry Eric if the one that came as an A hole was my self:-)
The point is that what Emmanuel does, compliant or not, works.
Standard are standards but often there are ways to skip the constrains and what an application won’t take another one can do it work. As long as you are able to print it in a disk, players shouldn’t have much problems to play it.

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 !

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

Did you try MPEG STREAMCLIP ?

For the demuxing?

That the first tool I tried. It doesn’t work. It’s known that mpeg streamclip is not a good tool to handle HDV, unfortunately…

Well, i don’t trust the DVD SP workflow.
If it’s slow, there is something going on like transcoding.
Demuxing must be a very fast process.
Rafael told you about FFmpegX, that would be a good bet.
I would use plain FFmpeg, and use a command line.
Very easy, just run ffmpeg -i infile -vcodec copy -an video.m2v for video,
and ffmeg -i infile -vn -acodec copy audio.xxx (no idea what your extension should be)

Ok, spoke to soon.
I just ran a test, and it does indeed just demux, and indeed, slow.
Except from some header / footer information, the file is identical to an FFmpeg demux.

So, FFmpeg (or any front end app. like FFmpegX) will do the trick for you.

Thank you for your help.
I have tried ffmpeg. It doesn’t accept my HDV files.
I have GUI ffmpeg. I’m going to try again.
I f you have other ideas, let me know.

I had no idea of the DVDSTP demuxing capabilities neither how to do that with FFmpeg (scared of terminal, command lines and that sort of things here here).
A very instructive thread indeed.

[emmanuel Presselin] “I have tried ffmpeg. It doesn’t accept my HDV files.”
Some times things works changing the file extension.
I’ve worked often with VCDS, which internal files are “.DAT” (text files?). QT open them just changing the extension to “.mpg”.

What version of FFmpeg are you using, on what platform?
And, what is your commandline (do copy/paste…)
