First Frame is black with H.264

Hi !

I'm using Resolve 9.1 lite and i have a strange issue.

The first frame of every clips i converted in h.264 - mp4 with Adobe Media Encoder CS6 is Black.
I verify in Premiere Pro and After Effects, the first frame is a real picture, not black one.
This is.... so annoying, i rendered all my files to the exact frame i needed and the first one is not usuable.

Any idea ? Similar Cases ?
thanks !

Is Resolve replacing the first frame with black, or is it adding a black frame to the beginning?

It replaces the first frame with black.
The clip has the timing expected (frame duration seems ok) but the first frame is black and the overall video is shifted of 1 image.

Here a screen comparaison of what i got (davinci VS premiere pro)

[list=][*]A : first frame in PP (footage)
[*]B : first frame in Davinci (black)
[*]C : second frame in Davinci (exact same as A)
[*]D : last frame in PP
[*]E : last frame in Davinci
[*]F : Laste frame -1 in premiere pro (exact same as E)[/list]
The shot doesn't show obvious difference i know, you have to pay atention to the head

Thanks to take time to resolve that problem, it is very appreciated

I'm having the same issue. Did you ever find the solution?
