Well, I think that is the crux of it.  My GT5040 does not even have the horsepower to play back Blue-ray.  Looks like I will need a new processor (dual core or equivalent) which probably means a new computer.  Not sure, but I am sure learning a lot (the hard way).

Hallo, I'm new in this forum. I am an italian user of dvdit pro hd and edius broadcast (with procoder express).  When I try to import a mpeg-2 (1980x1020 - 25 fps) the message is always the same: it's not blu-ray compliant.
Any suggestions?
Thanks.
I apologyse for my bad English.

Hi Massimo

A lot of information on this in the forum, just use the search feature.

For Final Cut and Compressor users, please make sure to,

In Final Cut  changed the
"Sequence Setting",
"Starting TimeCode"

to 00:00:00;00 instead of the default value of 01:00:00;00.

If you don't, chapter markers may not work.

Dear Scott,

Judging from your information, I simply guess DVDit Pro HD won't accept H.264 stream as an asset. I have Final Cut Studio 2 and HD DVD creation was supported and am looking for proper tool for BD creation.

My questions are:

1) if DVDit Pro HD can read H.264 ES prepared with third party encoder such as Apple Compressor and MainConcept.

in case it reads H.264...

2) does it use original H.264 stream and just multiplex in building BD data/disc?


Your kind assistance will be appreciated.

Regards,
Shin

H264 is NOT supported.

HD-DVD is not supported (full solution) on any MAC, unless you have made one and can tell us how you managed that?

Has anyone done any successful encodes using Telestream Episode Pro?

[rexdigital]

has anyone done 720P 60fps?

someone mentioned 24p support works, but technically ALL
720P is 60fps.

so has anyone tried it?

Hi, I've just purchased the DVDit Pro HD for Blu-ray authoring purposes.
My MPEG-2 HD files are created in TMPEGEnc Xpress 4 using the settings available from this forum (except perhaps for the bitrate, which is adjusted for 40Mbps CBR). For short content they do seem to work, but I guess with longer duration files, DVDit Pro insists on reencoding the whole file.

This might be some overhead bitrate present in these MPEG-2 files generated from TMPEGEnc Xpress, but since I preset the encoding for CBR 40Mbps, I don't see why such thing would happen. Some fast motion or complex scenes perhaps...
Note that I don't have a software that can show me a bitrate graph, so this are all assumptions.

The way of "ingest" MPEG ES files in DVDit Pro HD for Blu-ray authoring is sort of awkward. I see the window that tells me that all MPEG files are due to reencode, but sometimes they do reencode, and sometimes they just are multiplexed...

Is there a real way of knowing exactly what is wrong (if) with ingested MPEG-2 files created by third party applications?

A warning box could have some informations such as these:
- Warning: Bitrate exceeds Blu-ray specs. (41Mbps)
- Warning: GOP exceeds Blu-ray specs. (GOP: 60)
- Warning: wrong color primaries: (Rec.709)

and so on...

Since the software seems to parse the MPEG-2 file in order to analyze it anyway, a tip in order to discover what is really wrong wouldn't hurt.

The problem is most likely that the encoder isn't perfect and just a few bits over 40Mb/s will put it over. I dont think it's good practice to use the max bitrate ever. Try using 35Mb/s maximun and rest easy.

[Mboufleur]

Yes, I might do that. This is one small issue, but the fact that we don't really know what is going on is the real problem.

And the idea of a warning box is neat, isn't it?

[SS Scott]

I do like the idea of the warning box...something to check into.  FYI on the bit rate.  For 1080i MPEG-2 content, you probably don't get any discernable benefit from a bit rate beyond 25,000kbs.

[Mboufleur]

Well, that depends.

I did see the diference going from 25Mbps to 40Mbps in scenes with a lot of in-motion content.
Has anyone seen Carnaval? Wonderfull brazilian celebration, but try to compress it...
Same with football matches...

And to make it all worse: both contents with 30 frames per second, plus interlaced...

Sometimes I do get a sense that one has to be masoquist in order to work with video these days...

For film content with progressive frame rate, I think I might not see improvements over 25mbps, since it's the bitrate most titles sold in Blu-ray are using right now. But then again, it all depends on the source material.

Anyway, I apreciate the fact that you considered the warning box. Hope to see it in the future.

Hallo,
for all the PAL-User:

Using Compressor is possible with DVDitHD and 1080i50-material to create BDs.


After a couple of tests to find out, how this works, I found the cloue why it was not working at the beginning. I got stuck with an error (error creating DB).

All you have to do, is to UNCHECK the checkbox "add DVD Studio Pro meta-datas" in the EXTRA-Tab, that is checked by default. After this you can choose any BD-setting that can be created with compressor ( within the specs).

after this, you got through it all and you could create BDMV-folder and the image, too.


I found out that using an HFS+volumen as target-drive für the image could cause problems, but haven´t checked this especially. It seems to me, that it´s better to mux the disk to a win-formated harddrive.

take care of the start-TC 00:00:00:00 as well, instead of 10:xx or 01:xx, otherwise you lose chapter-marker while muxing.
