Pal to NTSC

[Avi Liani]

Dear ALl

theater asked me to bring Blue Ray disc with video 24 as frame rate, 2048X1152 or 2048X1080, and NTSC format.

My footage originally is in PAL, I know I can convert by compressor. COuld you tell me how it is done. I could not find any tutorial for this.

I think I must indicate in setting NTSC format as pixel aspect ration. Am I right? but there are two choices: NTSC CCIR 601 /DV and NTSC CCIR 601DV (16:9)


When I actually indicated NTSC, the movie dimensions were changed and picture looks ugly, like squized
This video must be shown on big screen, so it is theater quality.

Please tell me what can I do, also regarding Audio setting, I do not know where I can change 16 bit to 24 bit. I think 24 bit is better.

thanks a lot

There are quite a few misunderstandings here:
- there is no PAL or NTSC in HD, just different frame-rates
- the standard for HD is Rec 709
- 2048x1152 is no Blu-ray format
- I suppose you shot 25p, right? My recommendation is to slow it down by 4% with the help of Cinema Tools – faster and better than conversion

thanks for reply.

1. What is blue-ray format then?
2. I was told in compressor when I make blue ray I must indicate NTSC in aspect pixel ratio, It is wrong?
3. I see 24 frame rate in Color originally, I think it is shot on 24 frame per second. How can I check it?

If you have a Quicktime file you can right click on it -> info or (cmd info) and it'll tell you if it is 24 or 25p
Blueray I think is 1920x1080 (I don't know how the codec works and if it's still 1920x1080 once encoded)
To go from 24p to 25p you can do it in Cinema tools -> conform and tell it it's a 25p file. It just plays it at 25p without rendering (metadata change). The film will be shorter and sound pitched a bit but you won't have any motion artifact caused by the rendering in Compressor.
If you want to go from 24p to 29.97 (wich is the frame rate of the NTSC format...) you probably have to do it in compressor.

thanks man all this info is real help for me. I am economist, first time I made movie, I spent all money on production. I did editing myself and I can say I did it well and far better I think than director or other editor can do, because editing is not just techniques but like chess and mathematics puzzle. But now I stuck in technical problem, I should do everything by myself because I do not have any budget. and I am doing theatrical movie, not TV or DVD. I should prepare DCP and blue-ray for small screens in theater. With DCP theater guys told me they will do it themselves.

I need to burn blue-ray my self I am just about to test my color corrected shots how it looks like, then I will decide to render whole movie or correct some colors again.

So I need a help how to record best quality video on blue-ray. And yes I do not have 5.1 sound. I have stereo and it is OK for small screen room in theater.

So I need direction from where to burn blue-ray, toast? compressor directly? what format, resolution I already know, if HD does not have pal or ntsc, they guy form theater insists that I should have NTSC format.

So what does it mean then?

I have know all rendered shots in FCP sequence. So from there what to do is my question to get best quality on blue-ray.

If that sequence in FCP is 24 fps, 1920 x 1080, just go to "Send to…" choose "Blu-ray" and burn it. Can it be any simpler?

1920 by 1080 in 24 fps is a Blu-ray compliant format.

Yes I noticed that option in FCP but did not tried yet because on one forum creativecow I think, I was told that you did not get the best quality.

For best quality you should use any burner, but I do not know which and what is workflow for that.

Yes frames are indeed 24fps and I renderred it 1920X1080 format in color already.

There is also option in compressor to write on BR, also Toast, I have heard of other progs, but I cannot figure out which is the best choice.

You know I am checking color correction on big screen so I need very good quality on blue-ray to see if some colors have any drabacks

thanks and regards

Compressor and FCP use the same compression engine. Toast is not any better.

Better encoders don't come cheap.

What the name of the best software for this then?

or it is more than with hardware rather than soft?
