How big is a typical hd movie formatted for the ipad? Also is it possible to get my pdf journal articles onto the ipad. If so how do I go about doing this.
 
They vary. I have one that is 5.36 GB and one that is 1.7GB. Depends on the encoding.

Ripping DVDs into DVD-quality movies weigh in between 500-700MB. I use Handbrake which is a one step (on the Mac) process. The trick is to encode videos at the lowest bitrate that looks/sounds acceptable to you. (DVD quality is good enough for me) Not only will the files be smaller, but it takes less resources for playback resulting in longer battery life.
 
What program are people using on the pc. I have a bunch of movies formatted for my iphone, but I am sure they will look horrible on an ipad.

Anyone know about the pdf's.
 
When you purchase a movie from itunes to the ipad is resolution compressed? Or it the same file size as a dvd?

I keep hearing this, that movies are typically sub 1 GB. But I encoded 70% of my DVD library in HB prior to August 2008 (when I started a renovation and my iMac went into storage for 10 months) and I used what were the generally accepted settings for getting movies at optimal bitrate, size, audio, etc. for playback primarily on an Apple TV with the version of HB that was out at the time and I don't think it has changed that much. I always used H.264 output with full widescreen and AC3/AAC for DD 5.1 on my Apple TV at a avg bitrate around 1500-2000. Most of my ripped DVDs are 1.5-2.5 GBs each. Something like LOTR Extended Edition, each of the 6 discs are 2-2.25 GB. Now it all plays back great streaming from my iMac through a FW800 external drive over N wireless to my Apple TV and playing on a 52" Samsung LCD, so I wonder if it is overkill and should I be using a lower setting. I haven't commenced ripping my library since bringing the iMac out of storage but obviously if I can save space I would like to without compromising video quality. I have no intention of syncing any of them to an iPhone or Touch and since they will sync at that size to an iPad I am not limiting myself from that device. I know that you can't go above 640x480 for an iPhone. I also know that any movie in SD from iTunes is about the size of mine and the new HD iTunes movies are 4-6 GB for just the HD copy.

Don't be so sure that they will look horrible on the iPad. It depends upon how they were encoded.

On a PC, I use DVD DeCrypter to rip the .vob files from the physical disc and then run Handbrake to convert the .vob.

The latest version of Handbrake seems to have some improvements that yield smaller file sizes. I have no specific proof other than most of my DVD encodes with version 0.9.3 averaged between 2-3 GB yet after updating to 0.9.4, most new DVD encodes were less than 2 GB, using the same settings in both occasions.

Can you give some basic settings you use, similar to what I stated? And do you go with higher bitrate as is most universally accepted or do you think there is no loss creating 700MB files? As I watch most of my stuff on a 52" LCD, that is where my concern is. I don't mind the storage size because I am not optimizing for laptops or iPads or iPhones. And it seems to be in line with what the file sizes are for SD when you buy from Apple.
 
I was just going to go out and get an ipad, but they are sold out at both apple stores and best buys that are in my area.
 
Filesize = (bit-rate / 8) * (length in minutes * 60)

rule of thumb

720p usually weighs in at about 3.5Mbps
 
Here are a few examples of HD movies I've converted for my iPad. All were converted with HandBrake 0.9.4 using the "Normal" preset. All of these examples are 1280x720.

Avatar - 5.29GBs
The Hurt Locker - 5.41GBs
Zombieland - 1.36GBs
Wall-E - 1.37GBs
Cars - 2.74GBs
Lord of the Rings: The Fellowship of the Ring - 3.31GBs
Lord of the Rings: The Two Towers - 4.15GBs
Lord of the Rings: The Return of the King - 4.3GBs
