Stan, I did a little testing last night as follows.
I took a one minute segment of some beach volleyball that was showing poor quality on my initial DVD from Pinnacle Studio, and exported this 4 different ways
1) MPEG2 DVD Quality
2) MPEG2 1080i (same as my original 37 minute problem video)
3) AVCHD HD 1080
4) MP4 1080
I imported these one at a time into Encore, encoded as DV HQ 8MB CBR (except the DVD Quality file which did not need transcoding). I burned a DVD for each. The results all looked pretty good and pretty much the same between all 4 discs. The MPEG2 1080i disc didn't show the same poor quality that my iniitial 37 minute video did, even though they were exported from Pinnacle with the same settings. So then overnight, I tried re-transcoding the original 37 minute MPEG2 1080i file using the same DV HQ 8MB CBR from Encore and burning the disc. This morning before leaving for work, I popped the DVD in and went to the volleyball clip, and it looked terrible during the fast action, same as before.
So I am a bit perplexed by this. The only thing I can think is that because the 37 minute project has much more data in the project, and the MPEG2 1080i video file is about 7.2GB, maybe Encore is not allowing the same data rate. even though I told it to use the same transcode setting than the test using the 1 minute clip.
Not sure where to go from here, but I have exhausted so many 9-hour long transcode settings, and my project is way overdue. I would really like to know what settings to use from Pinnacle as well as Encore so that I can save off the highest quality file from Pinnacle that will allow me the highest quality in Encore so that in the future if I ever want to go back and re-export the project as Blu-Ray or something else, that I have the files I need. I guess I will just make the DVD with the MPEG2 DVD quality export file, and just save off the Pinnacle Studio export in all 4 formats shown above, not knowing which one will be needed in the future.
Any other suggestions or ideas?
