Your client wants MP4, so I guess for a web site or to be played on a computer.
Then FORGET about NTSC, and ANAMORPHIC.
You are in SQUARED PIXELS-land.
Leave the ANAMORPHIC button UNCHECKED.

[jonathan young] “When I compress the 480 video I am using 853X480 with a 16:9 anamorphic NTSC setting (which should make 720X480),”
That’s very wrong.
Set 853x 480 Squared pixels and uncheck Anamorphic.
In fact, 852×480 would be better size for the compression.

I’m with Michael.
Don’t complicate your life at this stage.
Beside the technical issues of editing with two different time bases, you may end up with an uneven product where people may notice the difference between shots made with on one or the other time base.

You can “fine tune” the file size when you are using scalar codecs where you set data-rate, GOPs length and key-frames (you trade file-size by quality), but you can’t do the same with production codec that are Intraframe and have a fix data rate.
Your only solution is to use a more compressed codec and the best option when dealing with 10b Uncompressed footage is to convert to Prores. You will reduce the file size to a fraction of the original without compromising the quality.

On FC, drop your Uncompressed movie on a new sequence, and conform the sequence to the movie settings.
Change the sequence codec to Prores HQ and make sure that in the “Video Processing” tab, is checked “Render in High Precision YUV”.

Your best option is to convert to Prores HQ.
That, or to get a dual-layer disk.

Animate the text size on the “Control” window.

Don’t you have your Final Cut project with the original footage?

You have a preset in Compressor:
Other Workflows > Advanced Format Conversion > Standard Definition > SD 10b Uncompressed PAL.

– Duplicate the preset.
– Change the Codec by the Prores HQ.
– Set “Frame Control: ON”.
– Set the re-size filter BEST.
– Set Field Order “Upper-first”.

[Stuart McAlister] “If I click on ‘Initialise’ then it takes me through to Disk Utility and clicking on both icons for the disk reader (see attachments), the root of the reader is ok but the disk within it, isn’t.”
Click the reader and see if down on the interface you have a “Mounting point” option.
If so, click it.

[jonathan young] “What I am trying to say is why does the 720X480 have to have a 16:9 anamorphic pixel aspect ratio to come out correct but the 640X360 have to have the square pixel aspect ratio to come out correct.”
720×480 is made of NTSC PIXELS.
If you check “Anamorphic”, it will be 16×9.
If you don’t check Anamorphic, it will be 4×3.

Think of the pixels as tiles.
NTSC pixels, NTSC Anamorphic pixels and Squared pixels, all have different shapes/proportions.
NTSC and NTSC Anamoprphic are rectangular. Squared are squared.

[jonathan young] “when I add the 16:9 anamorphic setting to the aspect ratio of the 640X360 I get the video that turns into 540X360 with the green vertical bar on the right hand side of the player?”
If you check Squared pixels as Anamorphic, you are distorting the pixels. They won’t display Squared any more.
Squared pixels are just that “Squared”. No option for Anamorphic.

Make sure that your 640×360 is SQUARED PIXELS.
