Black line in the bottom of the video (MJPEG codec)
on Jul 27, 2017 at 2:47:33 pm

Hello everyone,

I'm trying to edit a video in Premiere CC, but when I view it in the monitors, there is a black line of 1 px height in the bottom of the image. When I scale de image, the line goes away.
What is weird is that when I view the same video on VLC, there is no black line.
I would appreciate any toughts that might help me getting rid of this line (without the scaling).

might be a codec issue.
Just scale it up one pixel.
