Creating Proxies

I'm creating H.264 proxies. I'm on Premiere Pro 13.1.5 and using Media Encoder 13.1.5

Each time I do this, my proxy ends up with the very first frame copied at the beginning, shifting the entire clip over one frame. ie. 

A,A,B,C,D,E,F,G,H etc..

 

Why is this happening?

 

Source is:

Iphone X

24 fps

4030x1704

 

My encode settings are:

 

I've already attempted to use ProRes for my proxies, but the result was choppy and unusable. Same with CineForm.

are you sure it's not vfr.  use media info to check

drag a sample video file into the mediainfo window and then hover over the video area and you'll see a list of specs including whether it's vfr or cfr.

I would guess on account of that original file being VFR ... variable frame-rate ... which will be a bear to work with in a proxy process.

 

Before importing it into Premiere, use the free Handbrake applet to convert the file to a fixed CFR ... constant frame-rate ... state.

Sorry again, to be more specific, the footage was shot in Filmic Pro and is 24 fps, not VFR.

Sorry, I should specify, this doubling of the first frame happened when I encoded to ProRes and to CineForm as well.
