Heuris MPEG Power Professional DTV HD

[d121]

Just download Heuris MPEG Power Professional DTV HD software which encodes avi to mpeg2 with 720p resolution. The demo version encodes up to 8 seconds video only. Retail price is over $8,000.

Is there any way to get over the 8 seconds limit?

try purchasing it, im pretty certain that will work

PS read rule #9 again please.

I appreciate that it has the (as-yet rare) ability to encode high-res MPEG frame sisez, but on a more general note, I'm interested as to whether or not Heuris have actually improved the output QUALITY of their encoding engine, or if they've simply tweaked the existing 2.0h engine to allow greater flxibility over input/output parameters. I always liked the range of available options in Heuris 2.0h (esp. the possibility to output directly to VOB - something Derrow will know all about!). The speed was also quite acceptable, but the downside was that encoding quality, while not bad, was nothing special either. TMPGEnc has always trounced it on this issue.

I can't be bothered to download the demo right now, but I just might do so in a few days time, not for the H-D res, but just to see if the MPEG output quality's improved at all.

Is there anything else out there that has an HD option? Or is this about it for now?

[Arky]

Erm, don't hold me to this, cos I've never tried, but I *think* that fantastic little piece of code (Still criminally underrated IMHO), TMPGEnc, can encode massive frame sizes, and can also go above Main-Profile-&-Main-Level standard. I'm not familiar with the requirements of Hi-Def' MPEG encoding, but TMPGEnc is so extraordinarily flexible, that it'd probably cover most bases in this respect. The downside, of course, is that TMPGEnc is horrendously slow at the best of times. I truly dread to think how slow it'd be doing Hi-Def' frame sizes! :scared: :scared: :eek:

The Ligos LSX-MPEG encoder can also encode HD content, but it can't compare to TMPEG. I have done some HD MPEG2 encoding and TMPEG is simply the best, quality-wise, and isn't bad speed-wise either. I think the latest version of ProCoder (1.2) supports HD encoding. There are some other HD MPEG2 encoders but they are more "specialty" and in reality, low-quality.

Nahie,
which version of Tmpeg do u use, did u do 720p?

[Nahie]

I try to always use the latest version, but I think TMPEG has supported HD encoding since version 12a. I encode 1080i and 1080 24p.

[benf2]

What is your source for the HD encodings, Satelite? DVD?

[Nahie]

I work for a company that produces HD computer animation movies, so I encode their stuff.

[benf2]

cool!! I am curious if its possible to encode a dvd thats 720x480 to HD specs, at least 720p.

[d121]

Hi Nahie,

What are the settings in TMPEG to encode to 1080i?

Yes, that would be possible (I'm talking purely on the basis of framesize here, all other paramters notwithstanding), but I am not sure I follow your reasoning - why on earth would you wish to interpolate to a larger frame size? You will not gain anymore detail, so surely this is self-defeating, isn't it..? In fact, for a given bitrate, you will *lose* quality because the bitrate is spread between more pixels, to say nothing of interpolation inaccuracies.

True, didnt think of that:(

Just set the resolution to 1920 x 1080 and instead of main profile at main level, you can set it to main profile @ high level or high profile @ high level. Also HDTV bitrate should be at least 18mbps to 40 mbps.

[Arky]

*40mbps*!! :eek: WHOA!!! that sounds like FUN!! :devil: Can't wait for those damned blue-laser drives to hurry up and hit the market - I NEED CAPACITY and I need it NOW!! :D

i thought the mpeg-2 limit was 15mbit?

HDTV is about 4x the resolution of SDTV, so it needs 4x the bitrate. I'm not sure what the absolute bitrate limit of MPEG2 is but I have encoded up to 25mbps and it played fine on my hardware HD decoder.
