I'm simply trying to setup a 1080p video. All the video sources are 1080p, here are the initial settings:

Initial 1080p Settings

However when I import and drag a new (and definitively confirmed 1080p) video to the timeline the preview shows a small black border on the left and right sides. I even removed the "Tile Safe Area" and "Action Safe Area" and the left/right black borders still appear.

The only thing I've noticed is that on the project panel is that the video info column shows the video at "0.75" [unknown units]. I am absolutely certain that the video is 1080p (1920x1080).

How do I fix this to get an exact one-to-one ratio for 1920x1080? The input videos are recorded via Open Broadcast Studio and the settings seem to be good. I've been trying to test things out to figure out what Premiere CS3 does support (very very little) to increase compatibility.

Wrong Aspect Ratio

  • It seems that your 30p video has been recorded with PAR=0.75, which makes it 1440x1080, not 1920x1080. Still, this should not preclude it to properly render to 16:9 DAR. I have no idea what Premiere does not like. Also, just wondering, where did you get 30.00 fps video? From a smartphone? – Rusty Core Mar 4 '19 at 18:10
  • @RustyCore "The input videos are recorded via Open Broadcast Studio" - the videos measure at 1920x1080 when played in Media Player Classic without the black border; how would I make sure OBS shoots it in true 1920x1080 then? – John Mar 4 '19 at 20:06
  • First you need to verify the params of your video using something like MediaInfo: en.wikipedia.org/wiki/MediaInfo It may as well be 1920x1200 if this is native resolution for your monitor, then when resized to 1080 lines, you will get pillarboxing. – Rusty Core Mar 4 '19 at 22:38
