MPEG2 in Compressor
Hi everyone,
I want to export a MPEG2 whit the CableLabs Profiles Specification whit compressor! But my problem here begin when I choose the codec MPEG2 in compressor.
When I’m in the Video Format of MPEG2 option, I can’t change de video format… I only have the choice between NTSC, PAL, 720P,640×480 and others one…. It possible to make my custom choice ? For example : 528×480?

This is a good question, I’m interested in a response. It may be to set a separate resize…but I’m not sure u could do square pixels with mpeg2.

When I look at my Videos specification from the broadcaster I find MPEG2 resolution at : 528×480 …. :S

“CableLabs Profiles Specification” Not sure what this means…but I can tell you that in the 10 years I’ve been producing video, I’ve never seen an aspect like that. It’s some sort of almost square aspect. NTSC DV video is 720×480 with either a pixel aspect ratio of .9 (for 4×3) or 1.2 (for 16×9)
The square pixel equivalent of each of these respectively is 720×540 and 864×480 (or 853×480) I may be confusing 864 in relation to D1 video which is 720×486.
So unless this video has been cropped, or it isn’t a standard frame size…it seems that your aspect would be out of proportion.
I could be wrong….I don’t deal in broadcast very often.
A program that is much more full-featured in creating custom settings is Episode Pro, it has a ton of options when making custom transcode settings.

Up to this, your video must be plain DV NTSC 4×3 48Khz (720×480/Interlaced).
All the specs for your MPEG-2 (dara-rate, GOps,..) are on this document.
If you need help, ask on the Compression Techniques Forum.
