white lines

[jriker1 16]

I have 1080p ish videos that look fine on my PC with VLC but when played in Emby thru my NVidia Shield Pro 2019 on my 4k LG TV, I see a white line at the top and bottom.  Can't see the bottom when paused.  I say 1080p ish as the video is 1920 x 1040.  File is MKV and HEVC

 

Note I don't see this in Edge browser playing it also thru Emby.

Hi, is this on all videos?

Hi.  These are all relatively "old" sources?

Have you tried adjusting any of the Shield processing options (like their upscaling)?

Can you clarify old sources?  They are old videos but few things:

 

1. These are newer remastered Blu-ray sources.

2. They have been processed and cleaned up thru Premiere Pro.

3. They do not show this when played on other devices.

 

Luke, I'll check other sources.  I know the one other one I tried was the same.  Also will see if I can play them on the Shield Pro with VLC and how they present..

Thanks.

So this is odd.  In Premiere Pro I do two things:

1. Run the file thru NeatVideo to remove grain

2. Crop off the black bars

Now personally, if I left the black bars or took them off, the display should basically be the same.  Other than some font oddness with ASS subtitles.  Anyway, the resulting file with removing what black bars I could visually see left me with a

1920 x 1040

file.  Normally this would be the end of it.  But I have these lines at the top I mentioned.  I rant he file thru ffplay and did a cropdetect.  It comes back with: 

crop=1920:1024:0:28

So it thinks it should be 1920 x 1024

I just cropped it to 

1920:1034

Don't think I can see those lines anymore.  When I blew up the 1920 x 1040 file 400% I could maybe see some lightness of the very top area of the video, but wouldn't this have shown if I never removed the black bars?

Perhaps they were an artifact of the crop operation itself.

Trying other videos would be a helpful test as well. Thanks.
