HD quality question

[alaskamovieguy]

New member here thou I have participated a little on adobe. I'm having a quality issue when viewing my HD on my sony 42" 1080p. I'm editing avchd files in PE7 with transitions and added music track. Exporting a 8.5 min movie from Share/PC/MPEG2 1920x1080i preset and then burning the resulting file in Roxio 9 avchd on DVD. For the most part it looks excellent, as good as going straight from the camera thru a hdmi cable to the tv. There is one wierd thing thou, some parts of the video have a 'video tick' approx. every 1 second where things get a bit blurry. This happens primarily in distant background areas and especially where there is panning or zooming. I tried a seperate project using only about 1 minute of the worst areas with the same export and burn settings and the problem was hardly noticeable. I also tried using a custom preset, VBR 2 pass 18_25_30, quality 5 and setting the burn speed to 6x instead of 16x and still had the same issue. I'm currently using TDK 16x DVD discs thou after reading the forum here I have ordered some Tayio Yuden. I don't think it's the blueray player or the tv since I was able to eliminate it for the 1 minute test clip. Any advice would be appreciated. Bob

Hi Bob

I edit AVHCD from a Sony TG7VE. My workflow is similar to yours however I only output the Mpeg2 file. I have never noticed the tick you speak of, but then again I play my films via a Sony PS3 and never burn to disc. I just thought I would mention it in case you had access to a PS3 to test the file to isolate the problem to the DVD burn process. Good luck with finding a solution.

Thanks for the advice thou I don't think that will help. As stated in my post I tried 1 min clip of the worst area of the video as a new project (no transitions is the only difference) , exported with the same settings and burned with the same settings and that eliminated 90% of the problem. I guess I will reproduce that 1 min test and make sure I used the same settings and get the same results.

Alaska, you do realize you're going from AVCHD to HDV then back to AVCHD again, right? Limiting the number of conversions could help your quality issues.

Also, are you playing your resultant DVD on a BluRay player and viewing it on an HD-TV? I just want to confirm how and where you're judging the final quality.

Hello Steve. When you say I'm going from avchd>HD>avchd, is there a way to avoid that while still getting some minor editing done with PE7? When I export from PE7 Share/PC/MPEG 1920x1080i preset is that converting from avchd? The resulting file ext. is m2t. I am playing the DVD on a blueray player and a sony 1080p TV with HDMI cable of course. By the way, purchased your book and it has been a helpful.

Appreciate the welcome Chuck. I feel like I already know you, Steve, Paul LS, Winesnob and various others with all the forum info I have read recently.

Well, since you've got an AVCHD MP4 going in and you're working in AVCHD project settings, it's best to output an AVCHD MP4 from your Premiere Elements project (since your goal is to have an AVCHD in the end).

Unfortunately, someone else, with more AVCHD experience, is going to have to tell you how to do that. It's probably going to mean creating your own output preset.

Just a follow up note for anyone reading this thread...I eventually solved my problem with some expirmenting and Paul LS suggestions for workflow. I now have edited avchd on standard DVD disc with excellent quality. Project edited in PE7, exported in h.264 1920x1080, CBR matched to camera, in my case 17MBs. I imported the file to Corel videostudio which seemed to do a better job handling the h.264 file, burned avchd to dvd using 1920x1080_2 pass_8x burn speed. The results were great, I can't tell the difference between the dvd and the original out of the camera, perhaps if they were playing side by side, but this looks good. Thanks to all!

Glad you got it sorted and thanks for posting the solution.
