Brian,
Re-reading your posts, it seems like you exported your 1440×1080 project out to 1920×1080, and then are taking that new file and re-exporting that to 720? That is encoding TWICE, so introducing additional compression loss. You are blowing the image up larger, then shrinking back down again, not to mention the compression hit.
From the original 1440×1080 timeline, you can export to 1280×720 from there. From Premiere through Media Encoder, from source to final delivery codec.
Thanks

Note that it is not recommended to use the render previews for your final output, so unless playback quality is intolerable, I do not bother rendering in the timeline and just let that happen during final export from AME.
Thanks

OK, so you set the size to 1920×1080, but if you did not also change the Pixel Aspect from 1.33 to 1.0, that might explain it. Please verify settings

Hi Michael,
Since CS5, Premiere can accelerate a lot of things using select Nvidia graphics cards. On the Mac Pro, you’ll have the Quadro 4000 option, but nothing for laptops, so you will experience a performance hit versus a similar PC with Nvidia technology working for you.
Thanks

Hi Dylan,
Noise reduction plugins take forever to render, this is normal. What I do is use After Effects and apply noise reduction (Red Giant Denoiser II in my case) to the raw clip and export to a new file, then Import that new, clean clip into Premiere and then there is no lag during editing and I can add other effects and such in realtime again. That way the noise reduction is not dogging the system while I am editing.
Here’s some info regarding the render bar colors in Premiere that may help explain the how and why of what you are seeing – https://blogs.adobe.com/premierepro/2011/02/red-yellow-and-green-render-bars.html

Hi Brian,
Regardless of the source you are editing, or the Sequence setting, if you truly exported as 1920×1080, 1.0 PAR Square Pixels, then indeed that is what the resulting file specs ought to be. By chance, in AME, did you have “Match Sequence Settings” turned on or something? Can you provide a screen grab of your export settings for review?
Thanks

Hi Rich,
I watched the video (is there supposed to be sound?) and they don’t appear to be doing a “key” at all, rather they are just creating a rough mask with a feathered edge I think.
Notice the black halo around the talent? Not a real key right to the edge of person. Limited usefulness I think, only working properly with a dark background as shown.
“Keying” black out is called a Luma key and works the same as a Chroma key, but I don’t see where that would work with a person because eyes, hair, glasses, a belt, even nostrils are all areas that could potentially have holes cut in them with a black key.

If you have CS6, and camera motion is minimal in scene, you could try the Warp Stabilizer effect, set to NO MOTION. This can provide a rock-steady video, onto which you could then overlay your sky/background.
Otherwise this is a job for a motion tracker as Ann suggested
Thanks

Hi George,
So you’ve never made a Blu-ray disc, and I’ve only made 1080i Blu-rays, so now what? What a team we make. I looked in Adobe Media Encoder, and Encore, to see what presets they offer for 720p Blu-ray and surprise – no 29.97!
I see frame rates of 23.976, 24, and 59.94 offered. I don’t have a camera that shoots 720p and therefore have no experience working with or burning 720p formats. All been 1080 the last 4 years.
So perhaps you were on the right track of encoding to 1080p30? Otherwise we’re looking at changing the frame rate and I’d expect better results changing the frame size rather than the rate. Hopefully someone with experience in this area can share some insight?
Thanks

Hi George,
Are you are Mac or PC? In either case, Blu-ray uses specific settings for either H.264 or MPEG-2 files, and any clips not meeting these criteria will be transcoded (recompressed)as needed by Encore to create the disc.
So the question is, what format did you output from AE? The 720p 29.97 is the frame size and frame rate, but what “codec”? Default is “lossless” which creates very large, uncompressed files. In the Output Module, you can go to the drop down list and choose “H.264 for Blu-ray” and then also make sure to check the “Audio” box at the bottom of Output settings window, else you will export video only.
You will end up with TWO files, one video, one audio. In Encore, choose “Import as > Timeline” and grab both clips together then.
Alternately, you may be able to import whatever you have right now and bring that into Encore, and it will transcode to the correct format before burning.
I would stick with the original 720p for Blu-ray, won’t look any better by upscaling and may even lose some quality in the process.
Thanks
