MXF, OP1a

[Thomas Nord]

I believe what you are looking for in AME is the MXF OP1a/XDCAM HD 50 NTSC 60i preset. That should give you a video file that is compliant with the specs you are looking for.

[jason levy] “I have explored Media Encoder.. I see MXF OP1 but no signs of MPEG2 in that setting. There is a MPEG 2 setting but no OP1 in that… “

Jason, just follow what Thomas said above. He nailed it.

Once you chose the MXF OP1a format then you’ll need to change the codec portion of that format. The drop down menu next to “Video Codec”will allow to chose from the various installed options. XDCAMHD 50 NSTC (4:2:2) is a MPEG-2 based codec for broadcast, and the one you’re looking for.

Ryan, Thomas,

Thanks very much for that. Appreciated. File looks good. I’ll send them off one to evaluate before I convert 48 episodes!

I notice that AME also created an .xmp file. I gather that is metadata and I’ll look into that more tomorrow. If either of you wanted to fill me in on that I would not complain! And gladly buy you a beer if you ever end up in Montreal.

Again, thanks for the help.

You’re exactly right. The XMP file is Adobe’s open-source solution file format for embedding information into a given file, or what’s commonly known as metadata. Depending on your workflow and needs it may or may not help you….

So that seemed to come out fine except for one thing.. It’s 4 channel audio, with stereo mix on ch 1 and 2 and M&E on 3 and 4. When I play the file back (using MXF4mac Player) from what I can see the mix is on all 4 channels. Have double checked the source and it is right.

Any thoughts on why the 4 channels don’t get copied as input?

Again thanks.

Jason

Sorry I think I figured that one out. Set audio to “4 channels”.

Again I notice that in AME I can create a setting for

1920 x 1080 @ 29.97

or

720 @ 59.94

but not

1920 x 1080/59.94 as requested..

Likely something about this that I don’t understand. Any suggestions are appreciated.

Audio didn’t work.. I get 4 channels but 3 and 4 are silent… sigh.

[jason levy] “1920 x 1080/59.94 as requested.. “

This is an aspect where people throw numbers around without clarifying what they mean (not direct at you, but more of our industry as a whole). So 1080i59.94 is 1080i29.97. That’s because 1080i59.94 refers to fields per second which is 29.97 frames per second. So if you’ve set it for 1080i59.94 the only frame rate you’d chose is 29.97 (unless you were doing a 23.976 conversion).

Anyway, you’re on the right track with that.

Did you ever sort out the audio channels? I am in a similar situation now…

[Jason Levy]

I did find a way to do it. I bring the files into Premiere first. In Premiere you can set up a sequence with the appropriate audio channels IE 4 of them and then you send it all to Media Encoder.. it retains the proper outputs.

I believe I used this tutorial to figure it out…
