With the arrival of Quicktime 7 and the H.264 codec HDTV content is now light enough to be transmitted over the Internet.

Will FinalGear use it for future encodes of TG or FG when the encoder becomes available on Windows?

So far the trailers will only play on a Mac with Quicktime 7

Batman Begins stats

* Duration: 2:24
* File size: 115 MB
* Resolution: 1280x544
* Video codec: H.264
* Audio codec: AAC

XVid is still good though but I think there is always room for improvement.
 
115MB for 2:24? :shock2:

I think it won't be necessary to start using that.
 
After reading this, persuaded my housemate to download the Serenity HD trailer. Same sorta size, but looks really really sweet.
However, his computer jumped and skipped a lot - this is a one and a half week old, top of the range PowerBook which is unfortunately a G4. It definately needs a G5 to run.

Looks really really nice, but don't think the computing capabilities for playback are quite there yet - capable computers need to become more widespread - this is made worse by the fact that this is still a Mac only codec... (but it's really making me tempted to go out and buy the PowerBook I dream of, maybe when the PB G5 comes out... 8) )

[Edit] Ah yes; also as Bihus says, 120 odd megs for a couple of minutes is alot of download requirements with the current broadband speeds widely available... maybe when broadband gets universal faster will this become more popular... [/Edit]
 
H.264 has a fantastic quality and has better compression than xvid / divx.
It is the future of digital video, and it will be used for the next generation DVD (HD-DVD).
The reason why it is so big is probably because:
- It's high resolution (1280x544)
- It is probably encoded at a very high bitrate.

BTW, I have played H.264 files of similar size on my P4 1.8 before and it didn't stutter at all.
It is might be that the codec still needs optimization, but yes, H.264 will need a decent computer.

I noticed the high resolution too, but that's the whole point in HD, right? I just think it is to big to compensate the gains. But for some purposes, of course I wouldn't mind having that kind of quality. :)
 
IMHO, it's a good choice to use H.264 regardless (once the codecs are mature):

At the same resolution, bitrate and quality, an H.264 file will have a smaller file size than xvid / divx, etc...
At the same resolution and file size, an H.264 file will have a higher bitrate and better quality than xvid / divx, etc...
 
monkey: even on a dual 1GHz PowerMac it would still run below the normal framerates unless I shut down everything and just play the trailer.

I was hoping that VUK's encodes could be jacked up to Standard Def or better. Maybe a higher bitrate could be offered?

Imagine watching Top Gear & Fifth Gear on your TV at a better bitrate. ;)

Hopefully Apple will release QT7 for Windows soon.

remember, it is a higher res video file than "normal" DVD, but about the same bit rate (6-8 mbps)


sure, these arent the setting to use for streaming video, but both Blu-Ray and HD DVD clans have committed to using H.263 to replace MPEG2 on next-gen optical.
 
^Yeah, at that bitrate you could fit three hours of video onto a 9GB DVD. That's pretty good for 1280x544!
 
Aint gonna happen...for now :shifty:
 
It's QuickTime, so no thanks. :yucky:

But anyway, 720p / 1080i are insane quality. Here's some more examples using WMVHD: http://www.wmvhd.com/

I have 3 1080i .TS movie rips and true, they're 10-12 GB, but still, the quality is insane.

Here's a screenshot of Gladiator for example:

 
h264 has been around for a while
quicktime player just supports it now
or maybe mac just copied it or w/e

h264 is not quicktime only
 
Oh, well then find me something that can play whatever's in the original link 'cause I refuse to install QuickTime on my computer and QT Alt. won't play it.

They aren't that much better quality (they aren't broadcast in HDTV). Here's some screenshots Overheat made of his H&L rips:

100% (approx 700mb)

175MB (approx 25%)

Plus, we had a poll on which people would like to see, 175/350 or 350/700 and it was decided that the current filesizes are a good compromise between quality and filesize. I mean hell, look at how much Vuk can do with 175 MB (from the Viper/Corvette episode of Fifth Gear):

FG & TG arent being broadcasted in HD or is VUK's feed not in HD?

Nope just digital, there's no HD in the UK yet, afaik it's America only.
 
Yeah, Vuk grabs the digital broadcasted signal, but it's just a digital version of normal TV. It's not high res.
 
They may very well be in the process of upgrading, but atm there's no HD. :)
