converting .m2t to .mpg

[Terry Esslinger]

.mpg files are compressed as are HDV (m2t).
.m2t IS an MPEG2 type file.
You render your HDV (m2t) file out depending on what you want to do with it. If you want it rendered out at same quality as you started with (except for edits) you render out as HDV m2t) which is an mpg file. If the intent is a DVD (which by definition is SD) then you render out as mpeg2 DV. There obviously will be some degradation. If you are going HD it depends on whether you are going to BluRay disc. Then use one of the BluRay presets (probably 1440×1080 for HDV). You can also use the Sony AVC or Mainconcept AVC.

Thanks for response
I have to turn these files in on a DVD and I was given the following Encoding specs to go by:
TV Standard: NTSC
Video Format: Mpeg 2
Encoding Type: Constant Bit Rate
Bitrate: 10,000kbps
Field ORder: Progressive

Audio Format: Mpeg
Audio Mode: Stereo
Frequency: 48Khz
Bitrate: 224Kbps

They want gave some examples of how files should look and they all have the .mpg extension. I just wanted to make sure I gave them the right thing. If I render out as mpeg 2 DV will this give me the .mpg extension and be what they want from me?

Where did they come up with these specs and how do they plan to show the DVDs?
The audio is no problem nor is the progressive as Vegsa can be set up to render to those specs.

The bitrate is too high though.
No one that I know ever encodes anything at a CBR of 10,000 and expects it to play properly.
The recommended CBR rate is only 8,000 and that’s with good name brand media like Taiyo-Yuden.

As Mike has said just use the NTSC DVD or PAL DVD template and make the necesssary changes. i.e. constant BR of 10,000 (which is highly questionable) and progressive. That will give them what they asked for, but maybe not what they really weant.
