Having Problems Rendering Out My Projects
I have a strange problem that I can’t figure out using Premiere Pro and Adobe Media Encoder in CS 5.5 Production Premium. Whenever I select my output to H.264 format and using anything with a resolution of 1920×1080, I get weird interlaced like effects that are exaggerated when there is motion on my monitor. It doesn’t matter if I select my output file as interlaced or progressive. I get the same problem. I have tried several different settings in the options but have not had success.
My source material is 1920×1080 60i and 1920×1080 60P. Here again, the source material doesn’t matter as the problem occurs no matter.
The only way I can figure out to properly render out my projects are to export directly from Premiere and use match sequence settings. Here it will use a MPEG preview as the format and the codec is MPEG I-Frame not Main Concept. The outputted file in this format seems to be approximately the same size as if I used H.264 and the quality seems really good. But I don’t have this file output option if my original source files are 1920×1080 60P. It only works when my originals are 1920×1080 60i. And of course, if I want to watch on my TV or burn to Bluray, I will want the H.264 format — not this work-around.
The only other alternative that seems to work is to render my projects out to 1280×720 using H.264 and the Main Concept engine. The quality here is high but I can tell that I have lost resolution from the original clips.
I’m not a professional. I just need this to work so I can make home videos.
Please help. Thanks in advance.

Please try to actually BURN a Blu-ray and try it in the living room. Computer displays don’t always show what you expect to see for various reasons. You could be worried about nothing, when in fact the Blu-ray might come out just fine. Just use the “H.264 for Blu-ray” preset at 1080i 29.97 and make a sample disc and try it.

Just found out something. If I render my project out to “H.264 Blu-ray”, I get a perfect quality conversion on my 1080 60i material. I can also get a good render from 1080 60P to 1080 60i.
The problem with this is that I don’t want to burn a Blu-ray disc. I get a separate video and audio file that I can’t play on my computer. The only way I can play these are to load them up in Premiere and importing the video file to a video track and then importing the audio file and placing that on an audio track for viewing.
This is not an option as I would just like to play these rendered projects for TV viewing via PS3 as well as just a file format for computer viewing.The strange thing is, if I take a look at all of the preset settings for the H.264 Blu-ray option and copy these settings to the regular H.264 render option in Adobe Media Encoder, I still have the weird bad quality renders.
I also notice their is no default H.264 1080i 29.97 option or any interlaced options for that matter, but it is certainly there in the “H.264 Blu-ray” presets.

ANY video that is meant for computer viewing should be deinterlaced, since computer displays are progressive. That is why you see 1080i presets for Blu-ray, but not for H.264.
Is your computer monitor full 1920×1080? If not, then you could be seeing scaling issues in the playback application.

My monitor is 1920 x 1080 native. 23″ Samsung C-PVA.
On my system I think there is something wrong with the way AME handles H264 versus the H264 Blu-ray encoding.
But I think I have found my solution. It takes more steps than I originally thought would be required. I will post when I make sure of my findings.

Jeff,
Thanks for responding and trying to help me.
I think there is a fundamental difference between the “H264” and “H264 Blu-ray” encoding on my system even though both report using the Main Concept engine.
If I use just the regular H264 to make a file, I can’t get good quality whether I specify an interlaced or progressive file. I have tried several settings. I even wrote down the settings from the H264 Blu-ray preset and put the same values in the regular H264 encode and I still have problems with my rendered files.
My solution is to use the H264 Blu-ray default preset, which makes a separate video and audio file. The video is an MP4 file and the audio is just a Wave file. I can’t even view this MP4 video file with Windows Media Player, but I can view it by opening up Premiere and importing it.
The next step I take is to start an Encore project and import the MP4 and wave file. Then I go and build my project as a Blu-ray folder – not a Blu-ray disc. After finishing the build, get a bunch of Blu-ray files in the exported folder. Inside the Blu-ray folder, I can find my project video file in AVCHD format which plays beautifully on my computer using Windows Media Player. The quality as far as I can tell is perfect. My clips that were originally shot in 1080-60P look the same on initial inspection even though I had to convert to 1080i.
I’m finally happy to have found a solution. I sent several projects from Encore to my PS3 and the finished video looks even more impressive than I thought it would be possible on my TV.My next question on my mind is whether I should even bother with making my source clips 1080-60P? I just bought a new camcorder and according to Camcorderinfo, I get 200 more lines of vertical resolution with 1080-60P over 1080-60i. I get more resolution but I have to convert my 1080-60P clips and render them to 1080-60i for TV watching — so which is more important? Obviously I would like to have the extra 200 lines of resolution but is there a loss in the conversion to 1080-60i?
