DivX.com has some High Definition Trailers !

http://www.divx.com/movies/trailers.php

For those we know are going to ask, here are the technical specification/characteristics of the new DivX HD trailers:

- Source: D5 tape (captured at 1920x1080i or 1280x720p)
- Preprocessing: frame decimation if needed, no noise reduction
- Resize to 1280x720
- DivX 5.2 parameters:
o HD profile enabled
o Single adaptive bi-directional frames
o 2 pass encode at 3500 kbps
o Slow Mode

They actually look incredible, we are talking 3.5mbps, compare that to the 8mbps you can find WM9 HD trailers on M$ website...

Hi Gej,

For some reason you have not stated the resolution of either of the three HD trailers?

I'm pleased you decided to use an bit-rate of 3500Kbps, as this offers around 180 mins per single layered DVD~R/RW.

All as discussed here (http://forum.doom9.org/showthread.php?s=&threadid=68292).


Cheers

Trailers are encoded at 1280x720 progressive @ 3.5mbps

The Bourne Supremacy looks very watchable.

Time for me to buy a higher spec graphics card with plenty of on-board memory... me thinks!


Cheers

[bond]

good move, now people might stop thinking that HD is something only useable with wmv9 :D
you should call these clips DVD-HD or so :D

[Soulhunter]

Nice... :)

Btw, any chance to see some 1080i samples in the future ???

Ah... no AvP HD trailer...
It's a killer for codecs.

There's no doubt that DivX's HD encodes look very good indeed given the bit-rate.

Being able to generating encodes with loads of pixels at comparatively, low bit-rates, is what Mpeg4 is all about - in my opinion. It's certainly one of my favourite interests.

I've downloaded all three of HD encodes and played them back on my HD plasma screen... it's just what the doctor ordered :).

Can I have more please?

Plz, give me a link !!!

hey just ran bourne supremacy through reocode 2 at 3000kbps and the quality was transparent to my eyes.

Just to confirm. Did you re-encode keeping the same number of pixels as the source?


Cheers

[chilledoutuk]

output video had identicle resolution as no resizing or filtering was used.

[Enigmax]

Congratulacions. Very, very nice.

Good work, DivX.

:) :) :) :) :)

Gej, can you manage to obtain an AvP HD trailer?
From what i've seen it's one of the "toughest beasts" to encode :)

[Sagittaire]

They actually look incredible, we are talking 3.5mbps, compare that to the 8mbps you can find WM9 HD trailers on M$ website...

all the codecs are able to make encodings in HDTV resolution:
XviD ~1.5 Mhz in 720p without PP
DivX5 ~1.5 Mhz in 720p without PP
DivX3 ffvfw ~1.2 Mhz in 720p without PP
WMV9 ~1.5 Mhz in 720p without PP
RV10 ~2.4 Mhz in 720p
VP6 ~1.5 Mhz in 720p without PP


Exemple with HDTV trailer source and XviD q2 encoding
384*216*24: 1688 Kbps soit 0.85 bit/pixel*fps
576*320*24: 2926 Kbps soit 0.66
720*400*24: 4523 Kbps soit 0.54
1280*720*24: 8870 Kbps soit 0.40


WM9 HD trailers are encoding with very low quant and very high quality (quant lower than Bourne Supremacy and very better quality preset).


For those we know are going to ask, here are the technical specification/characteristics of the new DivX HD trailers: o HD profile enabled


For exemple Bourne supremacy is a q3 encoding with IFrame and PFrame and without BFrame. It isn't encoding with HD profile: HD profil must be a n pass encoding to respect the RC profil specifications ... !!!


How a serious company as DivX.com can claim that its codec is 2X more powerful than the WMV9 ... ???

In fact for low quant(XviD q[1-3] for reference) all codecs give comparable results for HDTV 720p/1080p encoding ... !!!

here (http://jfl1974.free.fr/Video/HPIII.wmv) HPIII HD 720p trailer WM9 encoding ... :devil:
Picture Aspect Ratio 16:9 & Pixel Aspect Ratio 1:1
- Video WMV9 Pro 1280*720*24 2500 Kbps
- Audio WMA9 Pro 5.1 24 bit 192 Kbps

here (http://jfl1974.free.fr/Video/Catwoman.wmv) Catwoman HD 1080p anamorphic trailer WM9 encoding ... :devil:
Picture Aspect Ratio 2.35:1 & Pixel Aspect Ratio 4:3
- Video WMV9 Pro 1440*800*24 3500 Kbps
- Audio WMA9 Pro 5.1 24 bit 288 Kbps

[ripper64]

Great Quality, brilliant!

Once you've seen this quality, you don't accept anything else :cool:

Pity my monitor is just 17" :rolleyes:

Can't wait for BRDrips. :cool:

[kingmob]

The bourne supremecy gives me a CRC error :(.

[Sharktooth]

Uhm... here's a 1000kbps (!!!) VP6.2 HD (http://ebola.gamersrevolt.it/catwoman_HD_vp6_final.avi) (video only) trailer of Catwoman....

I don't understand why DivX5 or XviD isn't going to be a standard, while WMV9 is: Taiwan's ITRI* is developping the "FVD**" which uses the WMV9 Codec. This saves them some licensing fee per selled standalone device:

WMV9: $0.10
MPEG4: $0.25
MPEG2: $2,50 (!!)

DivX5 or XviD seems to me a better HD sollution since it spends the bits more efficient (lower bitrate required).

Now I'm a bit curious about the other HD alternatives like China's "EVD***" for instance.

* ITRI = Industrial Technology Research Institute
** FVD = Forward Versatile Disc
*** EVD = Enhanced Versatile Disc

Catwoman trailer doesn't work properly: I installed the VP6 codec, but the framerate is way too low.

The implementation of MPEG4 is far from a anything being a "standard".

Nice thread about it here (http://forum.doom9.org/showthread.php?s=&threadid=81511). from some companies i even suspect them to intentionally trying to brake interoperability.

This has to be seen, in my own experience RealVideo and WMV are superior to any MPEG4 encoder i have tried at low bitrates. H264 has a LONG road to go as well.

everyone can create their "standard" (anyone remembering the "bond standard"? :D ), the question is if anyone gives a damn about it

till now i dont think that these FVD, EVD stuff and who knows what, will be successful, but i do think HD-DVD will be, as its widely supported by a big bunch of worldwide operating companies and indeed as it looks like it will include wmv9 (no wma, nor .wmv) and h.264 (aka mpeg-4 avc)

[ripper64]

So the question is: Which HD format will be in the stores in the future and where and which codecs and disc-type.

Propably the BRD is going to be in stores, but which codecs?

Propably the BRD is going to be in stores, but which codecs? As far as I know. We are all still waiting for the HD DVD standards to be 100% agreed!

It IS an n-pass encoding, with b-frames, and no fixed quantizer, but VBV settings are lax enough to allow Quantizer to be consistent.

We have tested several clips produced by the studios and mapped PSNR against bitrate for both codecs. Results to be posted on DivX Labs soon. And we never said x2 more powerfull but 30% smaller bitrate at same PSNR than WM9.

[Sagittaire]

no comparaison possible ... high quality preset for WMV9 HD equivalent at q2 for MPEG4 ASP. Your trailer are encoding at q3 or q4. Winbledon is encoding excusively with q3 and q4 frame without bframe. Bourne Suppremacy is encoding excusively with q3 frame without bframe.

DivX 5.2 High Def profil 3500 kbps have in average the same PSNR that WMV9 MP@HL 5000 Kbps ... perhabs with VP6 but certainely not with MPEG4 ASP ???

In my PSNR test WMV9 is always better than DivX 5.2 for the same bitrate ... ???

Test in progess for HDTV resolution ... !!!

Gej, thanks.

Forgive me that I did not read it if it was there, but do we have sufficient rights to show these publicly, at a trade show or in store, for example, i.e., without any entry fee?

No. If you wish to do this you would need to contact our legal department, and also the appropriate studio/rights-holders.

[pogo stick]

Gej, DigitAl56K and other DivX guys, can I ask a question?
Are these trailers was meant as a start of something big, like alternative to m$'s WMV HD? Or it's "just trailers" to show DivX power and attract people? It's actually the question I was trying to ask some time ago here (http://forum.doom9.org/showthread.php?threadid=79141).
Unfortunately I can not download it right now, files too big for me. Is it avi's with mp3 sound?

[SeeMoreDigital]

Hi DivX guys,

The other day I downloaded and played the high-def version of, Sharks Tale (over at http://www.divx.com/movies/trailers.php)

Can you confirm if this clip contains B-VOP please?


Cheers

[Sagittaire]

bframe with ShartTale but this trailer is very blocky without PP: 3500 Kbps is a too low bitrate for this source ... it isn't high quality encoding ... :(

What tool/application did you use to identify B-VOP in this encode?


Cheers

[Mr_Schizo]

@SMD
Two commonly used ways to check this out are the MPEG4Modifier 1.2 and ffdshow's frame OSD.

What about GSpot?
v. 2.5.2 Beta 1 tells me about BVOP amd NVOP in the ShartTale HD trailer, but none of those in the Wimbledon HD trailer.

By the way, both play fine with DivX 5.2 and BSPlayer 1.01, postprocessing disabled, on an Athlon XP 1600+ (1,4 GHz).

[SeeMoreDigital]

Thanks guys!

I need to be 100% sure that the clip either does or does not contain B-VOP!

This is because Sigma's AVIcheck does not report B-VOP being present but some other tools do... And I was the newest GSpot Beta that I was trying to test :D
