Blue-ray only interlaced?

[cjonny]

If I create a blu-ray disc, I select disc output and then blu-ray. Then I click preferences because the standard 35mbps is too good for a 2 hours BD and select user definded. Ther I can change the rate tp 20mbps.
It works, but extremely slow, because my input clips are all at 25p (progressive) and not 50i (interlaced).
I cannot select progressive at all, although progressive is allowed as BD Standard.

Does anybody know how to create 25p as an output option?


It would help me a lot. Currently convert all my input clips for a BD from 25p to 50I. This is very cumbersome, but doing the conversion during disk creation takes ages - actually it never completed and my pc is not slow!

Hi

And welcome to the forums

Progressive is only Bluray compliant using 1280 x 720, if using 1920 x 1080 interlaced has to be used.

You should first convert your project to Share – Avch.264
Use this template AVC (1920 x 1080, 50i, 20Mbps)

Depending on your original video properties, are they AVCHD, if yes what are their properties
You could probably use those if they are Bluray compliant.

Render your project to a now video file
Start a new project to empty the timelines
Share create Disc Bluray opens the burner module
Add your video files here, top left Add media – Add Video Files.

Ignore the settings under the Cogwheel – project Settings, although you may wish to set Navigation controls

When you press burn the process should start with Create Menu, you should not see Create title.
As a test choose to burn a Bluray Folder, saves creating those coasters.

I suppose you could try converting to 1920 x 1080 x 24P that's the nearest if you need progressive.

You have to avoid the burner rendering/converting the files, so no Create Title

Trevor,
I tried your approach. It was only partially sucessful. It rendered the first file and then crashed, although all the input files had the same format as the first one VS crashed during the rendering of the second file (of 5 Files).

My cam Sony HX-90 has a lot of options for avchd recording, unfortunately it has only 25p (because of PAL?) and not 24p, which would have been blue-ray standard.
To avoid the crashes of VS X10 I edit the files from my cam to files of about 30 minutes max. to avoid crashes already in this step. Then I output the edited input to my PC and render it to 1080 50i 20mbps with X10. Then I take those files ( normally a total length of about 2 hours) into the edit window of VS and mark the chapters I want to have and than create an iso image with menus by setting the mpeg properties to exactly match the input files (i.e. AVCHD 1920x1080 50i 20mbps).

That works, because there is only very litle rendering for the menus necessary. But anyway even this method is very slow, it takes 4 hours for a 2 hour movie. But it avoids mpeg2 which I consider is an outdated standard.I then check the main video (0000.m2ts) in BDMV/STREAM by mounting the iso with clone drive and play it with VLC. Unfortunately VLC does not support menus on a blu-ray.

I hate interlaced videos, but that seems the only way to go with VS. So I changed the format on my cam to AVcHD 1920x1080 50i 24mbps. That saves me rendering and loss of quality. By the way my blu-ray player has no problems with 1920x1080 25p files on a blu-ray.

Thanx for the prompt and competent help.

Hi Jonny
Seems to be two issues here
First using Share to render your project to a new video file crashes, That does need fixing.
If it fails at the same point %age then it is probably something on the timeline.

Burning a disc, glad to hear you are creating a Folder and not making those coasters.
When you render the project if you choose a compliant Bluray option, the resultant video will burn to disc without further rendering, no conversion in burner module, no need to set the Change Mpeg Settings
Below that is Do not convert compliant Mpeg files this should be ticked. The main meaning “Do Not Convert” is what we are aiming for.

OK
From Video Studio Edit-- if we start a new project, that will clear the timelines
Share Disc – Bluray will open the burner module
Top left for add Media Add Video files.
Browse and add the compliant video file.

You mentioned adding Chapters, those may be available from the burner module, select Add / Edit Chapters, I believe there is a scan option, however all chapter names will need imputing again.

From the final panel hitting Burn should start the process as Create Menu.
If you see Create Title then the video file is being converted again, not what you want.
Test this with a BD compliant video clip.

If you choose to render your videos to 24P, you have to use the above as the burner module will not convert to 24P

You could save your work as video files and not burn discs, you can play the video on pc using USB memory.

From the image of your properties

I would expect the camera to record to MTS
Video Studio to render to m2t
The burner module to create m2ts

To burn a Bluray your 25P mts has to change, either to interlaced of the frame size to 1280 x 720
View the post from Ken with the BD compliant list, in an earlier reply……….


Right click your MTS file and choose properties, can you create an image of that panel to attach to your post, Alt + Prt Sc will copy to clipboard
Oh are your project properties the same as your MTS files?

Trevor,
I changed my Sony HX-90 to 1080 50i 24mbps. Then I recorded 2:01 minutes of video. Then I went directly to VS and added that video directly from the SD Card of my cam.
I added 3 chapters to that video and then created an iso image. The total process took 1:18 Minutes. No rendering of my title, just creating the menus and multiplex. I compared the output file with the input file, they are absolutely identical
That solves my problem. If I want to convert the interlaced to progressive and to lower datarate for Google Photo, I use XMedia Recode an open source that is very fast and reliable.
Thanx again, it sometimes just needs a partner to work on the problem. The key was that the blu-ray standard does not allow for 1920x1080 25p.
