Hey

I have two urgent questions which I need help in:-

1. I have been asked to convert a MOV to a mpeg 2
now the program I normally use is Sorenson Squeeze and Final Cut Studio Compressor ---
but I normally use Squeeze to do mainly mpeg One CONVERSIONS

I am not sure how to do a mpeg 2 conversion

here are the requirements:-

format: mpeg 2
width : 720
height: 480
crop to center: - 1.333:1
Padding: None
frame rate: 30 FPS
Aspect Ratio: 4:3
field dominance: automatic
average daTA RATE: 5 (MBPS)
MAXIMUM DATA RATE: 7.5 (MBPS)


Could you tell me the steps I would need to do --- to do something like this

2. I have a video (quicktime mov) which is a Pal format: 720 x 576
they have asked me to give it in a ntsc format -- both as 4:3 and 16:9
in NTSC format .
how would i do this if I was to export it as a quicktime movie as a 4:3 and 16:9 ---
please help
what settings would I set to make it in a ntsc format

Cheers

[Dan Newton] "what settings would I set to make it in a ntsc format"

You use the settings they have supplied you, start with an MPEG-2 NTSC preset and adjust as they have told you to:

width : 720
height: 480
crop to center: - 1.333:1
Padding: None
frame rate: 30 FPS
Aspect Ratio: 4:3
field dominance: automatic
average daTA RATE: 5 (MBPS)
MAXIMUM DATA RATE: 7.5 (MBPS)

It's not going to look great as you are 'standards converting' from PAL to NTSC. Ideally you'd get your footage professionally standards converted first.

I'm fairly sure that Squeeze doesn't support the mkv wrapper. Are you sure that's it's not m2v?

[Dan Newton] "yes m2v --- how come it doesn't have a mpeg output"

That is MPEG-2. 'm2v' stands for "MPEG-2 Video".

Your audio will be encoded as a separate file ready to be taken into your DVD authoring application.

Hey

Thanks for the feedback

ok two questions

1. I need to send the mpeg 2 to a client so they can view it on their computer and they only require mpeg 2 --- i don't want to send it to them seperately with the audio.

2. on squeeze there are numerous options ... I.E. lg, dvdlg etc... and when you are in the settings window --- do I set it on program or elementary and which option do I choose: lg, dvdlg etc..,

Please Help

You need to output a program stream on order for the audio and video to be part of the same file.

[Dan Newton] "so what would the output normally be"

It depends on the use of the output, but it will never be .mpeg but rather .mpg.

MPEG-2 can have the following extensions depending on output type.

.mpg
.m2v
.ts
.m2t
.mxf


etc..
