The First step is to do a Sequence Export that Matches the Sequence settings.

This will be your VIDEO file that you will combine with your surround sound mix.

REASON FOR DOING THIS IS you will make a "video mixdown" of your timeline

rendering out the file with all the edits and resizing.

Sequence Settings most common:

Look at the Timecode - should be 23.976 or 24

Frame size should be 4096 x 2160 or 3840 x 2160 or 2048 x 1152

Working Color Space REC 709

NOTE WHAT ASPECT RATIO OF THE SEQUENCE

Name your file

Choose Format > DNxHR/DNxHD MXF OP1a

Video Codec DNxHR HQ 8-bit

Then choose the frame size of your tmeline

>4K

>UHD

>Full HD

Depending what your timeline aspect ratio

Frame Rate should be 23.98

>Click on the Output Name

Title it and choose where you want to save the file by clicking on Location

Click on Export in the lower right corner

The file will export for a bit so wait for that.

In the meantime locate your Sound Mix files.

The sound mixer should of exported a Surround Interleaved 5.1 .wav file

The file should look similar to this 5_1.wav file

Don't want the ones labeled Stem they are not the full mix

We suggest making a new Bin to put the final files into for organization

>File>New>Bin

Title the bin >Final Deliverables or similar then open the Bin to import

the image and sound files into

Import the 5.1 Interleaved File into your Premiere Project

RT click in the new bin and choose Import

Select the file and import
Choose the Interleaved 5.1 .wav

Import the Video File you just exported that matched the Sequence Settings

Choose only the .mxf that exported there will also be a .xmp but you can ignore that

Click on the New Item and choose Sequence

Choose Sequence

Choose DNxHR HQ 2K 23.976
DON'T HIT OK YET!!

NEXT CLICK ON THE SETTINGS TAB

Click on the Settings TAB

Editing Mode - Choose Custom
Time Code 23.976 frames/second
 

1998 x 1080 settings for FLAT DCP's or 2048 x 858 for SCOPE DCP's

If you do not know if your film is flat or scope??

Do you have bars on the top and bottom of your image to make it look wide screen?

Then your film is scope.  

If you do not have bars then it's flat.

Still confused?  Ask tech staff to help.

Double click the video 2K or 4K file to load it into the source monitor

Drag the Video Only icon to your newly created timeline

Then load the sound mix (5.1 Interleaved) file into the source monitor and drag the audio only tracks to the timeline

Place on the 5.1 track in the new sequence you just made

YOU will be only able to check audio tracks 1 and 2 so you won't hear dialog but hopefully you can tell well enough.

The final check will be the QuickTime you will make next.

REMEMBER

DELETE THE 2 POP AT THE BEGINNING AND AT THE END

Drop down the Motion setting and on scale select that parameter

Drag the slider to scale the image in the frame

Scale the image down to 50% or until you see black around the frame then scale it up till you don't see any black

Don't want to see this small black edge to the right or left side

Scale till you don't see any black line on the right or left side

Flat DCP may choose to leave a slight letterbox on the top and bottom that is up to you

Scope DCP will have letterboxing on the top and bottom
