How do I render in MXF D10-30 for TV stations

Hi all,

I want to send a clip I made to a TV station and they have sent me their specifications that are identical to a lot of other TV stations in holland. Basically the following is written down in a document:

- It should be MXF D10-30 norm in Operational Pattern 1a,
- bandwidth is 30 Mb/s. Resolution 720 x 576 pixels with added 32 VBI lines (720 x 608). Frame-rate 25 frames / 50 fields per second
PAL signal must comply with ITU-R BT.601-5.

It's all very complicated to me...and not what I expected :)
Please tell me this is not as difficult as it seems, and that I can simply use the Sony MXF output format for this :)

And if so, which MXF output setting should I use in Vegas?

Thanks a lot if anyone can find the time to explain this a bit.


PS: The Norm is further specified by this information:

• SMPTE 377M-2004: “Material Exchange Format (MXF) – File Format Specification”

• SMPTE 378M-2004: “Material Exchange Format (MXF) – Operational pattern 1A (Single Item, Single Package)”

• SMPTE 379M-2004: “Material Exchange Format (MXF) – MXF Generic Container”

• SMPTE 386M-2004: “Material Exchange Format (MXF) – Mapping Type D-10 Essence Data to the MXF Generic Container”

• SMPTE 356M-2001: “Type D-10 Stream Specifications – MPEG-2 4:2:2P @ ML for 525/60 and 625/50”

• SMPTE 382M-2007: “Material Exchange Format – Mapping AES3 and Broadcast Wave Audio into the MXF Generic Container”

Isn't "MXF D10-30" a Mac/FCP thing?

I hope not....

You might want to try and Google "MXF D10-30". It appears to be a codec used in FCP.

EDIT:

Read this.

D10 is also called IMX by Sony. Choosing MPEG IMX with a bitrate of 30(CBR) and 4 audio channels under MXF should answer your TV station requirements.

How to get the extra lines for the VBI?

A D-10/IMX compliant MXF file based on SMPTE 386M (frame 720x608) should include the 32 vbi lines by default... Render your mxf file and check it with VLC...

It does, I just made a quick test run, MediaInfo and VLC both come up as 720x608, and there is a black bar on top of the video in VLC.

Thanks a lot guys, you are very helpful to me!

I'l try it out as soon as my computer is done rendering the same clip in 1920x1080 resolution, I started this and didnt realize it takes 12 hours instead of just 1 for lower quality :)

I also received a response from the support team at vegas which i wanna share with you too :

D10 is the IMX variation of MXF, used for standard definition programming.

The “-30” likely means 30 mbps. Our IMX presets are all 50 mbps, but you can easily create 30 mbps versions by starting with one of ours (any of them with “IMX” in the name, but pick the one that matches the project format in terms of framerate and standard vs. widescreen), hitting “Custom”, going to the Video tab, and changing the bitrate to “30 (CBR)” and then saving it back with a new name (I suggest using the same naming convention as our presets, but change 50 to 30).

So lets hope this whole circus of specifications I received is just a complicated way of saying: Just render the file in MXF with the IMX specs and you'll be fine ...

Cheers

Perhaps in future it wouldn't hurt for SCS to have a set of presets named by the matching SMPTE spec numbers.

I wouldn't call referencing SMPTE specs a circus. Those specs exist specifically to avoid the confussion that can happen when vendors go off and do their own thing.

What would it take for someone here to create some SMPTE render templates, can the rest of us then use them by just copying them into ex.
C:\Users\*****\AppData\Roaming\Sony\Render Templates\mxf and have Vegas recognize the template?
