First Blu-ray disc!

[kwshaw1]

I made my first Blu-ray disc last night using Adobe Encore CS3 and an input file rendered from Edius using the HQ encoding format. I was surprised that Encore accepted the HQ file and of course it had to transcode that to Blu-ray compliant format, but it worked! The resulting image quality is excellent in terms of color and resolution but has a 'juddery' look I don't see when playing my HD output directly, so I'm assuming the transcoding process did something which accounts for that.

My goal now is to render an MPEG2-HD file from Edius which will be accepted by Encore without transcoding, so I can skip that step and hopefully get better quality on the finished disc with less production time. Overall the finished disc looks great to an extent which bodes well for HD delivery to customers.

Congrats!

Nice to hear someone else having good results from Edius and Encore CS3. I have been working with the various Beta releases of Adobe Production Premium as a reviewer. I have been very pleased with Encore CS3 and have been authoring Blu-Ray for about 6 months. I got my LG Super Multi Blue (in advance of the general release for the review) about 1 1/2 month ago and have been very impressed with the disks. I have not seen the jittering that you referred to. You night want to check the spacs on your computer. The LG comes packaged with Cyberlink and has a very handy Blu-Ray / HD-DVD advisor that examines your system and lets you know if you are up to spec for playback.

I'm doing playback on a Sony Playstation 3, which works great with HDV files coming straight out of Edius. Since the main difference in going to a Blu-ray disc was the Encore transcode I figure I need to try working around that, which I want to do anyway to reduce production time.

What I have learned, over the years, is that just because it has it in the program doesn't mean that it is any good.
I use multiple programs for my dvd and bluray discs. Each program has been tested to meet my quality requirements at each level. Basically, it has been a 4 step program from start to finish.

1. Edit: Just what it says. You can use whatever you want
2. Encode: For me it is Procoder 3 or Sorenson Squeeze
3. Author: Encore CS3 or DVDITPROHD, and DVD Movie Factory 6+ for HDDVD
on regular and dl dvd.
This step also includes creating a 5.1 soundtrack if needed.
4. Burn: I use Nero to burn everything.

This has worked for me for years. I am not endorsing any product just giving you a work flow that I have used.

Happens when the source filed order is incorrectly assumed by Encore.

[mattmatt]

It could be a field order problem (encore's fault) but has anyone been watching Blu-Rays from the local Video store???? I watched three now, and all of them "judder" on pans during the movie? Has anyone else noticed this or is it just me?

I'm assuming it has to do with the progressive frame-rate not being high enough?

I'm watching them through PS3...

[GrassValley_BH]

What kind of display are you watching on, and what refresh rate is the display?

Mismatched framerate vs refresh rate will cause judder on progressive displays.

[mattmatt]

Watching on 42" LCD 8ms refresh...., but even at DickSmiths on the high end Plasmas, I see the same "juddery" pans.

[shueardm]

The movies are encoded at 24p but the display is probably not 24p native capable. So- it is either the Blu-ray player conversion or the display conversion that is to blame. If the BD player is set to output 24p then the display may be making it a 60i image. I think it is better to set the BD player to do the pulldown.

[GrassValley_BH]

Is the disc 24p or 50p?
Likely the display is 50p since you're in Australia...

[GrassValley_BH]

Hahaha Mark beat me to it.

[shueardm]

The displays here will handle all frame rates automatically excapt (most) don't offer native 24p yet. All movies are encoded at 24p from what i can tell.

Display woes

Excellent point about the displays. If you are using LCD then motion could be a real problem. I use a Panasonic PV700 50" Plasma as my preview monitor. My buddy, Gary Merson, the HD Guru has a very good article coming out in the Nov issue of Home Theather Magazine. You can read a preview at www.hdguru.com. One of the best ways to test your display is the Silicon Optics HQV high definition test disc. It has complete battery of test for your display.

I looked on this discs cover to find what frame rate it was encoded but didn't say. Just has 1920x1080.

The thing is, like I said before, On a Panasonic high end (over $6000 AU) 1080P plasma, I saw the same jiddery pans. During normal scenes, closups, fast action, etc - it looks spectacular! But typically on wide shots that are panning slowely, its jiddery / jerky.

I'm experiencing this in home cinema BR from Playstation 3, not output monitor from timeline.

Not to get into an LCD vs Plasma war, just wanted to know if anyone else has noticed this? (Hire "Shooter" and look out for it on the wide pans).

[shueardm]

That Panasonic model does not have 24p input, it will make it 60i.
Have you set up your PS3 with 24p output? Change it to off if you have.

Hollywood shoot 24p, they do not afaik nor should they convert it to 25p or 50p for Australian audiences.
