I Think I may misunderstand the issue, so let me rephrase it: You color corrected a clip looks amazing, brought it on your laptop to render, brought it back to your color monitoring environment and it looked weird?”

Yes, that’s the issue – I created a “color profile” on the reference monitor, when I exported and created an mpeg-2 dvd clip using the computer – it looked fine. I also created a test dvd disc, it looked fine.

I took this exact sequence with this color profile, and I brought it to another laptop, to finish rendering the whole clip to mpeg-2. I rendered the mpeg-2 clip and created a dvd disc, and noticed that the color is not good!

So I took this exact sequence with this color profile to another computer – rendered the whole clip to mpeg-2, the color was fine..

Any thoughts? It’s so strange…

Thanks so much for your response Angelo, to answer your questions:

1. Panasonic G25 plasma in THX mode (adheres somewhat closely to REC709)
2. laptop connects to it with Matrox MXO2 thru hdmi
3. a desktop connects to it via Aja Xena card (now known as Kona)

The “messed up” laptop is not connected to the reference monitor at all, it’s just being used to render a sequence with the color profile that was created.

The other desktop computer is also not connected to the reference monitor, it was just used to render the clip as well — and the color came out properly!

From what I understand, Adobe Premiere Pro doesn’t work with LUTS, why would this laptop be pumping out a different color given the same clip, color profile and program? I tried a fresh install on this laptop, same results…

Any ideas would be greatly appreciated,
Thanks

Thank you so much Eric.

I’m planning on making 1920x1080x59.94i blu-ray discs, it’s good to know that these discs will be playable in Europe as well!

What a relief, I’m so happy to know that I won’t need to create separate 50i discs…

Is there anything else I should know? This will be my first time creating blu-ray discs. Some things that I’ve noticed are:

– the color seems to come out very saturated on the blu-ray mpeg2 or mpeg4 encoded files, so I need to create a separate color profile than the original one that I used for the down-converted dvd… why is this, is there a way around this?

– it seems that blu-ray discs only accept 29.97fps interlaced encoded files, so I can no longer create 29.97fps progressive files for bluray.. It’s easier for the mpeg2 & mpeg4 compression algorithms to encode a progressive file, rather than an interlaced one… so the overall quality could have been better if progressive files were acceptable at this frame rate… it’s too bad about the blu-ray specs, I wish there was a way around this.

Thanks again Noah and Eric, any advice that you have to offer is gladly welcomed.

Sorry about that, I should be more specific….

When I wrote “NTSC Blu-ray Disc”, I’m referring to a disc that was recorded at 59.94i fields (or 29.97fps interlaced) at resolutions of either 1920×1080 or 1440×1080.

On the other hand, a “PAL Blu-ray Disc” would be a disc that is recorded at 50i fields (or 25fps interlaced). It can also come at resolutions of either 1920×1080 or 1440×1080.

A 24p or a 23.94p Blu-ray disc is universal and can be played on both NTSC and PAL Blu-ray players. Since most films are done in 24p, this is very convenient.

Question:
–What I’m concerned about, is whether an NTSC formatted blu-ray disc, one that was filmed at 1920×1080 at 59.94i (29.97fps) will also play in PAL blu-ray players and tvs?

Thanks for any advice on this.

[Alex Reyes]

Thanks Noah.

Do you know if the same applies to PAL Blu-ray players?

Meaning — would a PAL blu-ray player be able to play a 29.97i NTSC blu-ray disc?

Thanks,
Alex

Thanks, I already did.

I just needed to update my Nvidia Quadro drivers. Problem is solved.

Please help.. One of the experts here must surely know the answer? 🙁
