URGENT: Stuttering Frames on Animation

[p3taoctane]

I have been trying to render rout a large 1550 frame file.

I had to break it up into separate renders... not separate file ... just render 0 - 700 then break and then a day or so later render 700-----

NOTHING had changed in the file.. same save date and everything.

It is stuttering and NOT smooth after the first 700 frames. It is just a camera move only and no mesh movements or morphs.

ANY IDEAS.... for once I gave myself plenty of time but now it is getting close.

I rendered another camera out from the same scene and no stuttering 300 frames.

Maya 2016 and Ocatane 2.23.2 Batch rendered out at 1080P from a windows 7 64 bit pro with 4 titans no networking and textures not loaded offline.

I've attached a small zipped quicktime file so you can see what is happening.

ANY help appreciated.. getting nervous that this is not going to render in time.

Thanks

Ended up exporting an ABC file and putting into stand-alone and batch rendered from there.
Went fine with no stutter.

If you find out what may be causing it I'd still like to hear what it might be.

Thanks
