Custom Handbrake settings for Ipad?

I'm still trying to understand why any standard 2 hour movie playing on your iPad would need to be over 2 gb. These 3-5gb video files don't translate into higher picture quality, just more used space.
 
What processor is in the computer that encoded this movie? I did the same thing but mine took over 6 hours. Granted it's an old computer (P4 3.2ghz w/hyperthreading) but I'm curious what cpu you have.

Thanks

I just used Handbrake to encode Avatar (standard DVD) using some settings I found in the handbrake forums.

Video
H.264
Average bitrate 4000
MP4 file
(2 pass unchecked)

Picture Settings
Detelecine - Default
Deinterlace - slow
Denoise - Medium
Deblock - off
Grayscale - unchecked
Anamorphic - Strict

Audio
AAC Dolby Pro Logic 48khz 160 kbps


It took under an hour (well under an hour) and the file is 5.32 GB. I undertand this may not transfer via iTunes, I intend to use Goodreader if it doesn't. However, it does play over AirVideo just fine and looks pretty fantastic. I think I want to force the frame rate next time.

I agree that trying to use 720p settings on a 480p DVD is silly but Handbrake does a good job of up converting files.

BTW, I encoded the same movie last night using the Apple TV preset and the file size came out to 2.9gb and the movie looks excellent on the iPad.

Just an FYI.

Personally, I always use the Apple Universal preset for material sourced off DVD. Takes about 25 minutes per hour of video to encode on my 2.66GHz 2006 Mac Pro and uses about 1GB per hour of video. Looks great on everything (iPad, iPhone, Apple TV).
 
25 minutes per hour of video.... that's pretty good. I really need to upgrade my ripping/encoding setup.
 
You guys aren't even tapping into what the iPad can even handle.

Use the "High Profile" setting.. use a 2-pass, turn off fast 2-pass. I've even used a lowly 1000kbit for video on a 1080p and the result was amazing. I will be trying 1500kbit and 160kbit audio.. iPad should handle it fine too. And look all that more amazing.

Change Reference Frames to 5 on the Advanced panel.

Change Width res to 1024 and set Anamorphic to loose.

Start the encode.. transfer to iPad and be amazed. The iPad can handle higher profile encoding methods. It's very impressive.

Edit: 1080p video with a 3000kbit video date converted to 1024res with 160kbit audio. End result was a 480meg file for 1 hour of HD content. Looks phenomenal on the iPad.
 
It will be interesting what the handbrake group comes up with as an iPad preset (supposedly they are working on one). How long do your encodes take using the settings you mentioned?

Encoding time takes two primary things into considering. How many cores your CPU is and how fast they run at and what types they are. For me, I have a Core2Duo E8600 CPU which is 2 cores.. running at an overclocked state of 4ghz. It takes me about 2 hours to encode a 1 hour 1080p video using my settings. Or about 1 hour using a single pass or constant quality setting.

An optimal setup would be an i7 quad core with some overclocking involved.. they are ridiculously fast at video encoding.
 
I'm wondering what to use that will take full advantage of the iPad's screen, and also run on the 3rd gen iPod (I'd assume but don't know for sure that all iOS devices can handle the same video settings).

Right now I use Handbrake's iPhone/iPad preset, only with audio bumped from 128 to 160Kb/s, since why not? The results are fine on the small screen, though I can see some issues with motion I think, so I wouldn't mind higher settings for that even.

That leaves you with I guess 480x320 video max, and obviously with an iPad you'd want 1024x768 (or 1024xwhatever for whatever given aspect ratio)

I don't yet have an iPad, but seriously thinking about buying one, hence the interest.

If it matters, most of my video comes from my Tivo HD, so it's mostly 720p or 1080i. I've tried the Apple TV preset, and it absolutely will NOT play on my iPod. I'm assuming that's because it's using a constant quality setting, and when the resolution is higher than 480x320, you end up with a bit rate higher than the iOS max (2500Kb/s?)

Soooooo I'm really looking for settings that will give me 1024x??? video that plays on both an iPad and iPod, and not sure how to do that...
 
i use the apple tv preset with a custom string for my apple tv, 3G iPT, iP4, and iPad.
 
What do you mean about a custom string? I tried the Apple TV setting and it wouldn't transfer to my iPod.
 
Just tried another test-started with the iPod preset, bumped the resolution to 1024 width, bumped the quality up to 64.x%...and it won't copy to my iPod either.

I really don't know what you're supposed to be using :(
