I have been looking high and low for something to encode video to a HDTV mpeg2 stream but have not come up with anything.
Is there any software encoders that can create a HDTV compatible video stream???
Or is there a way to force tmpegenc to do it???
I have tried almost everything i know. Adobe premiere pro 7 with mpeg2 encoding just resizes the video to 720x480. Tmpegenc just says the size is wrong and i had a guy at work try with there copy of cleaner xl and he couldn't change the mpeg2 res.
Thanx

tmpgenc can do it fine - but the quality is only so so (not to bad)
main concept can do it fine also ..
canopus procorder can also do it ..
Vegas can also do it (uses main concept encoder)
Blade can do it (uses tmpgenc encoder engine)
Premiere can do it (6.5 and Pro (7))
high end HD encoders are much higher in price (MUCH!)
you use different matrix and gop settings completly ..
remember for HD you have to set Main profile and High Level or higher in profile and Level settings .."Each problem that I solved became a rule which served afterwards to solve other problems." - Rene Descartes (1596-1650) -
cleaner (any version) sucks at both speed and quality (awefull program)
squeeze I think can also do it -- squeeze has much better quality than cleaner (uses main concept encoder again - as does adobe above)"Each problem that I solved became a rule which served afterwards to solve other problems." - Rene Descartes (1596-1650) -
how hd is hdtv 1920x1280 perhaps? what sort of bitrate does that require 3000 min 50000 max

mpeg2 HD can go to 118meg/s bit rate -- and higher ..
depends on what you are going to play it back on ..
broadcast HDTV is 19.4 meg/s bit rate
HD playback servers for the most part top out at either 34meg/s or 50meg/s
the above for 1080p (i dont like 1080i) ...
almost all HDTV streams are ac3 audio and transport streams .. transport stream multiplexers are rare and expensive , i use manzanita multiplexers .."Each problem that I solved became a rule which served afterwards to solve other problems." - Rene Descartes (1596-1650) -
i am trying with tmpgenc and cannot get it to work, it keeps saying "window size is not accepted", It will encode the 1280x720 with mpeg1 but not mpeg2.
Mainconcept will not let me go to 1280x720, will max the res out at 720x480.
Adobe premiere uses mainconcept for mpeg2 output and is therefore also restricted to 720x480 (actually true ntsc so 720x540 with non-square pixels). ( I know this because i outputed a file with the project settings to the res of 1280x720 and the output mpeg was still 720x540)
nothing seems to be able to export true hd res with mpeg2, only mpeg1.
There versions of the programs i have used are as follows
mainconcept 1.03.01.00
Adobe premiere pro 7
tmpeg 2.511.51.160 / 2.520.54.163
Is there something i am doing wrong?? -
yes -- you didn't read my thread above completly is what you are doing wrong ..
check the level and profile comment above ..
but adobe 6.5 i now seem to recall might not be able to do HD directly but only to the stand alone MC encoder via frame serving .. though i would not use adobe premiere for HD work (After Effects yes though) .."Each problem that I solved became a rule which served afterwards to solve other problems." - Rene Descartes (1596-1650) -
Sorry i didn't understand, i just needed to look more carefully, then i noticed what you were saying, but the option for high level was not availble. That was with a newer free tmpg i dled, so i went back to my plus version and there it was
Thank you muchly -

Heuris makes a very good HD-MPEG encoder as well. As usual, it's $$$.
Don't worry, this is one of those things that will soon (1-3 years?) be taking the downward price slide. It's in the cards, be patient.
