PAL Blu-Ray – Flicker when previewing in NTSC region
Aloha,
So I was requested by a client last night to make a PAL blu-ray, and when I checked it on a Samsung Blu-Ray player and a Sony Bravia HDTV there was a lot of stuttering and choppy audio. I’ve obviously seen this before when doing SD DVD authoring, however never ran into this issue for Blu-Ray. I than checked it on a professional Sony Trinitron broadcast monitor which would play PAL content from Digibetas, and noticed the same result. Now I deduced it down to either the disk was bad, or that the Blu-Ray player doesn’t support a PAL Blu-Ray, but I didn’t think that was an issue with Blu-Ray. Here was my workflow:
1) Encode MPEG-2 1920×1080 PAL compliant file – play fine in VLC player
2) Use Toast 10 to make Blu-Ray Disk, making sure it is set to PALAfter the disk is done, I get the flicker when playing in the Samsung. I play the disk throught the burner on the MAC and use either VLC or Roxio Media Player that ships with toast and the Blu-Ray content plays fine without any jitter. All is good when going through the computer.
Is it just simply that the Blu-Ray player is NTSC and has problems playing the disk? Is what I sent out going to play fine in a Blu-Ray player sent in a PAL region? Anybody have any luck with this?

There’s no such thing as PAL in BD. Is that what Toast says? Hilarious! 🙂 What are the specs of your original file and your encoded file? Why is your client asking for a PAL BD?

As far as I’ve known so far, Blu-Ray is either 24 or 60 fps frame rates – but this is the first time I’ve seen this. When I take the PAL MPEG-2 into toast I’m prompted with the message:
“The TV standard currently set to NTSC, but all your content is in PAL format. Do you want to write a PAL dis or re-encode all content to NTSC”
I select PAL because that is what the client is asking for – even though I think I should have just made it 24 FPS. After burning the disk however, I have no success on playback on the Blu-Ray player. Plays fine on the computer – but no dice on the Blu-Ray player.
Curious if anyone has encountered this attempting this.

Like I said, what are the spec of your source?
Here are the specs:
High Definition Video
1920x1080x59.94i, 50i (16:9)
1920x1080x24p, 23.976p (16:9)
1440x1080x59.94i, 50i (16:9) AVC / VC-1 only
1440x1080x24p, 23.976p (16:9) AVC / VC-1 only
1280x720x59.94p, 50p (16:9)
1280x720x24p, 23.976p (16:9)
Standard Definition Video
720x480x59.94i (4:3/16:9)
720x576x50i (4:3/16:9)Blu Ray supports 50i or 25 fps but this is not PAL.

Original source came in on HDCAM:
1920x1080x59.94i, 59.94 (16:9)
We in turn brought it through an alchemist converter and made a PAL HDCAM at:
1920x1080x59.94i, 50i (16:9)
So I made a source file from this tape that was 1920×1080 @ 25 fps progressive. MPEG-2 of course, which I brought into toast. I get the flicker as a result.

what is:
[Schroeder Eric] “1920x1080x59.94i, 50i (16:9)”
???your video 59.94i or 50i ? 🙂
-
sorry, victim of cutting and pasting there – it was 50i
-
Make a 50i file and encode that. There is no such thing as 25p in BD. Also make sure you view it on a European monitor and player.
Also I said Euro specs support 50i and 25p – I meant 50i and 24p

You can create 50i Blu-ray discs, but no Blu-ray player I’m aware of can play them correctly. We’ve made several 50i Blu-ray discs for foreign clients, and none of the clients complained about them.

Yes, Thank you everybody.
I guess my question is centered around the folks in the UK. Have you ever received a disk that is 25 FPS that is progressive from the states and it plays fine in a PAL blu ray player? looking into it today as a result of damage control and being preumptive – I see that adobe encore will mkae a blu-ray disk as 50i fps – did I fuck up by encoding and make the file as 25 FPS progressive? Will this play properly?

You F’d it up :). There is no 25p in BD. Besides, you took an interlaced source and made it progressive. Make a 50i file and encode that.
