H.264 - 'One Format Fits All?'

Hi guys

Im very happy that iTunes Uk have finally released TV shows for download...
I have started ripping my TV show dvd's using a program called handbrake.. I optimise these files to fit the ipod.. I am definitelty getting an AppleTV and i will definitely get an iPhone. i have an Ipod 80gig (not a classic) just a black one... i also have a macbook pro..

SHOULD THE STUFF I RIP FOR IPOD VIDEO FIT ALL THESE DEVICES.. I DONT WANT TO RIP ESPECIALLY FOR EACH DEVICE AND HAVE DUPLICATES.. I WANT IT TO FIT ALL..

DOES THE STUFF I GET FROM ITUNES STORE FIT ALL DEVICES?

no, iPod has small screen and low res, if you want same video to play decent on tv, you need to set the bitrate to at least 700kbps, res at about 800x600. these setting are little bit high for iPod, but works on TV/computer better.

Honestly, I'd just wait until the touch ships and the iPhone gets updated.

It looks like there will be new video resolutions, so Handbrake will likely get updated presets for them. Just wait until someone has tried it out and found the best common format, nobody really knows until it's out and has been tested.

i did quite a bit transcoding for my palm tx, same screen size and res as Touch, for them, 480x320@450kbps is good enough, but OP want to watch it on TV/MBP too.

The same codec does work for all these devices. They just have different max resolutions and data rates they can handle. So you want the highest settings that will work on all your devices. Until the touch is out or the iPhone updated, I don't think it's really known what those settings will be.

H.264 is a codec, it does not have scalable feature.

When people say 264 is scalable, it just means that one codec works well for high quality, high bitrate content as well as low bitrate content.

Many codecs are optimized for one end of the spectrum and don't perform well outside of that.

The iPod and iPhone will be the limiting factor. If you want your video to play on all your devices, then compress your video at the maximum bit rate supported by the iPod and iPhone (which have the same video support I think).

Here is the iPod Classic video specs: (I think it is the same as the old iPod video)
H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per second, Low-Complexity version of the H.264 Baseline Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; H.264 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Baseline Profile up to Level 3.0 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats

If none of that makes sense to you, just use the latest version of Handbreak and use the preset options for the iPod.

Once you get an Apple TV, your existing content should look ok, but you will likely notice that the quality is not the same as a DVD. Try hooking your iPod to your tv to see what the video quality is like.

I found this information provided by apple is profoundly misleading, for the screen size of iPod classic,Touch, iPhone, 1.5~2.5mbps is a unbelievable waste of space. 60%~80% waste.

How's that misleading? They state the supported formats, NOT the recommended formats. Sure, the extra resolution is wasted on a small screen, but is it really worth re-encoding stuff to save space, if you want to use it on say, an iPod and an Apple TV? Plus, they apparently support TV out, where the extra resolution would be worthwhile. All that said, they're specs - they're not at all misleading.

LOL, rip at 800x600...

What you want to do is get them at DVD native resolutions, or just 640*576. At a nice bitrate. My ripped DVDs are at 800kbps for the good quality stuff and 500kbps for cartoon stuff. I've managed to fit the whole Futurama DVD collection into 5gb, looks great on iPod and my monitor (1680*1050).

The new iPods can handle a lot higher quality video.

Go check out the handbrake forums. There are people there figuring out what the new capabilities are the best settings for media.

I need to re-rip my collection, but I am going to give it a couple of weeks until the iPod touch ships and people figure this out.
