How to export a master?

I have some videos that are quite simple, but very sharp. For the purposes of this thread, you can imagine that they are all created a few solid shapes, a few solid colors, and text. They look very sharp. There is just a little motion blur here and there. All were created with 8 bpc.

I would like to export the videos and have masters and then do any future encoding from those masters and not have to open AE.

I don't care about file size AT ALL.

Here's what I'm thinking of using:

Format: QuickTime
Video Codec: Animation
Quality: 100
Render at Maximum Depth
Depth: 32
Key frame every 1 frame.
Use Maximum Render Quality

These are the video settings for the preset that I made in AME.

I can handle the audio settings I think.

What do you think of those settings? If I hadn't synced up the audio in AE, I would have probably looked into using a sequence.

Are these settings 100% lossless? My typography and edges are perfect and for the purposes of this thread are my main concern.

Thanks.
