"new Ipad" (3) , how do I get highest quality demo video on it ?

[Justin O'Neill]

To my eye high bitrate 1920 looks better than 32Mbit/s 2048 on the new iPad. I will render an example shortly.

Is there any hardware way to send HDMI out to use New ipad as a display?

[Jonas Klittmark]

Haha, so I'm not the only one thinking along those lines. Obviously it's not a pro tool, can't be calibrated etc. etc. but for $500 I'd be willing to give it a shot...

Yes, there is A/V cable for iPad3 with HDMI interface.
If someone could do the test using far above file turbine-lines to see if it plays cropped or squeezed via this cable, please.

This depends from application invoking the player used to play the clip.

It may play with black borders on each side or stretched.
Sometimes you will see the small icon on the top right of iPad screen that will give you option to streach it or sometimes this icon is grayed out.

All depends how application is invoking the player and if application is iPad3 aware or not.
Also what parameters are supplied to the function call invoking the player, like:
start in default mode,
use x,y parameters etc.

See my next post.

Am I correct that using 1920 for the source leads to the iPad upscaling to 2048 during playback which is why feeding it 2048 native is cleaner?

I know the display isn't that big but 1920 with one to one pixel mapping and a little black border might be the slick trick - sure would be nice to make one lower bitrate demo version of a piece at 1920 that you could show on a wide spectrum of devices rather than making a one-off for the iPad3. Or am I missing something?

But not for using the iPad as the display, right? Only the other way around?

I did play 2048 turbine-lines file on 1920 x 1080p Bravia 65" via AIrPlay.

File contains over imposed control pattern of vertical and horizontal lines spaced every second pixel.
AirPlay box used was AppleTV little box.

It plays perfectly clean cropped to 1920 so it cuts off 64 pixels on each side.
You need to use DroBox to invoke the file that invokes the player.
DropBox do not store file locally so it takes short time before it is downloaded to the memory and starts playing.
I did try to use Air Sharing app that keeps files localy in iPad3 memory but this app always invokes the player squeezed not cropped.
Also it is more prone to get confused and sometimes defaults to the iPad2 desk space.

What I was able to determine is that AppleTV box is very confused little box.
When playing iPad3 content it confuses iPad2 and iPad3 desktop sizes.
What a mess, will take time for Apple to fix it and clearly recognize the iPad3 2048 desktop size in all circumstances.

You can play iPad3 content via AirPlay two ways:

1) click home button twice to revile bottom line of icons of the apps running in the memory, next scroll to the player controls far left and on the right side of the controls, there you will be able to switch desktop replication to your TV screen by pressing small square button.

2) While playing a clip you will see on the right side of the player control buttons square button that will let you switch just this player session to you TV screen.

Apple TV box is confused less with desktop sizes and what is going on when you use desktop replication instead just switching player output redirection.

So to play 2048 file cropped instead squeezed:

Activate desktop replicator
Start the DropBox
Click on the file to play
Wait till it loads half the way to the end.
Play it.
You will see every line of the pattern both vertically and horizontally without any Moire distortion.
Playing squeezed 2048 produces terrible Moire.

Sometimes the AppleTV box is confused to the point that will shrink whole desktop to the iPad2 size and sometimes it will not.

I think AirPlay it is still work in progress.
I used newest firmware in AppleTV box.

BTW on another side subject (Nothing to do with playing from the iPad) AppleTV plays Apple TV content, like HD movies, very soft (DVD quality over HD 1920x1080 size)
Very visible softness on the 65" Bravia as oppose to the Cable feed from COX Cable.
What I am reading on the internetnet,
AppleTV uses 4.5MBits/sec stream.
The cable company I am on is using QUAM 38.8 MBsec bit rate and is using 2 HD channels per 38.8 bandwidth space or one HD 3D channel per 38.8 bandwidth. Sure Apple is using H.264 and cablecos are using MPEG-2 that is less efficient.
But this way or the other FiOS and COX Cable are looking like HD BR quality AppleTV is looking like DVD.

(Source of bandwidth information is Internet article, didn't check it myself)

This is very good question, instruction just mentioned "to connect your iPad to the HDMI TV"
But I have seen iPad playing laptop screen content replicated by AirPlay I think.

There is a way to show computer screen content on iPad, try google. I came across an article how to do it.

[Maxi Claudio]

There is an eyeTV thing that takes over the air SD TV and sends it through the Ipads port. So it must be possible to input a video signal. So I'm surprised no one has an HDMI to Ipod dock adapter. Even if the adapter down sampled the bitrate. An Ipod 3 would be a nice thin 9" LCD.

I take back my previous comment about high bitrate 1920 looking better.
