I'm burning a 2.30min clip onto a blu-ray but the resulting quality is very poor! The blu-ray is blured in areas and so is not usable. The video file that I am using is perfect when exported from adobe premiere pro and so I cannot understand why i am experiancing these problems. I have also been encountering the same problems when I burn to a DVD (using a different project in SD).
Obviously to solve this issue you will need to know an awful lot more and I am unsure of what info you will need so please can you instruct me on all the relevant info you will need.
Thanks john for the link
I am using Premiere pro cs5.5 and encore cs5.1 Both have all the recent updates.
I am using Win7 Home Premium 6.1.7601 Service Pack 1 Build 7601, Intel Core i7-3820 CPU @ 3.60GHz, NVIDIA Quadro 2000, HL-DT-ST BD-RE BH10LS38 SCSI CDROM Device
The footage i am using is HD1080p and i have exported by dynamic link to encore and on formats MPEG2 Blu-ray and H.264 Blu-ray both formats have worked perfectly when played with windows media player but after I have burned they both have quality issues.
I am also using Mercury playback engine GPU Acceleration, using a plugin magic bullet quick looks for effects.
Hope this info helps to find out what the problem is
I have one note on 1080p - http://forums.adobe.com/thread/995191 some work, some do not
CS5 Encore Files & Formats http://forums.adobe.com/message/1901666
There's 1080p and then there is 1080p.
If you're starting out from a transport stream of either MPEG-2 or MPEG-4 standard then the source is already highly lossy to start with.
Factor in recompressing yet again will only exacerbate any problems.
Can you please have a look at one of your aource files in something like MediaInfo, and post back the details?
Another possible culprit here is frame rates - have you changed the frame rate from the original at all, please?
Final thing I can think of is that if any of the source footage is even slightly blurred, frame rate conversion & further lossy encoding can make this appear a lot worse.
These were the findings from media info:
Original Footage: Gen: MPEG-TS (HDV1080P): 517 GiB
Video Stream: 24.4mps, 1440*1080 (16.9), @ 25.000fps
Exported (match source settings): Gen: MPEG-4(BASEMEDIA/VERSION2):548MiB
Video Stream: English, 30.5mbps, 1920*1080(16.9) at 25.000fps, MPEG VIDEO
I have not changed the frame rates.
Hope this info helps
Okay, I think I can see what some of the issues might be caused by here.
This is not actually full HD, but instead looks more like HDV to me, which means non square pixels etc.
It's also an MPEG-2 transport stream.
You are actually altering the pixel aspect ratio quite dramatically here, and then recompressing (admittedly to a higher bitrate but with more pixels)
You still ought to be getting a decent result from this though, so need to ask you some more stuff please.
How are you going from Premiere to Encore?
How did you create the sequence in Premiere - from a preset, or by creating new sequence from the Bin, and allowing Premiere to set the parameters itself?
Have you attempted to modify the footage - by this I mean looking at it's interpretation?
Is there any way you could send me the premiere project file (no assets) just to see what is what?
You may end up better off rendering a file from Premiere and avoiding dynamic linking......
BTW, 1920x1080 progressive scan at 25fps is not BluRay legal.......you need to either leave it as HDV (1440x1080 and interlace to upper field first) or else blow up to full HD as you have - 1920x1080 - but this again would need to be in interlaced, not progressive scan.
From your perspective, these are the allowed resolutions & frame rates:
i/. 1920x1080 (aka"Full HD") allowing frame rates of 29.97i, 25i, 24p and 23.976p
ii/. 1440x1080 allowing frame rates of 29.97i, 25i, 24p and 23.96p
