This looks like you may be encoding fields in your export?
If you could share the exact settings you use for your export that should be helpful.
23.976fps (soure file is 30fps)
VBR 2 pass
target bitrate: 46mbps (default is at 10)
max bitrate: 62mbps
time interpolation: frame sampling
Use max render quality: checked
Use preview: unchecked
The rest are in its default settings.
Please let me know if you are specifically looking for certain details.
Oh ya, by encoding field, do you mean encoding interlaced videos?
In that case yes I do, as most of my transitions are placed on top of the main video track. But only 20% of them flickered when exporting out. I am using handy seamless transition by the way, the premiere pro version.
And there are some occasions where i mask certain sequence to uncover the next scene.
Not sure if you get what i mean
If this is meant for web delivery, progressive (no fields) would be preferred and may resolve the issues above.
Are you working in a progressive Sequence?
Have you tried to export to built in preset such as High Quality H264?
