Convert 1080 to iPad?

I rip all my BDs to my unRAID at native resolution (sans DRM). I just downloaded HandBrake to start ripping for the iPad (might do some iPhone too). Since HandBrake doesn't have a preset for the iPad what's the best guess on the resolutions/settings for the iPod? It seems to me that 1024x574 (1024x434 for 2.35) would be the best resolution since there would be no scaling and it would be a smaller file size than a 720p file.

I'm brand new to HandBrake so I don't know many ends and outs so what do others think/believe/know of the best settings for 1080 to iPad and could you list them?
 
its been a while, but try the universal setting. That aims for a sweet spot that supports all apple devices, from AppleTV down to ipod. Should play just fine on ipad.
 
I would use 1366 x 768. This way, in case you'd wanted to zoom in to fill the screen, you would still get full resolution.

Edit: Nevermind, the iPad doesn't support resolutions larger than 720p.

Yes but that's 1280x720 so it would have to be down scaled (which could have some negative picture effects) and the files would be larger (less movies on each iPad) that going with a native 1024 wide.

1st Apple specs say 1280x720 max so 768 wouldn't work (or do you know something Apple's doesn't know or not telling) and 2ed not a chance. It's OAR or nothing for me. I don't chop off (blasphemy) parts of the picture to watch.

Yes, I forgot about the 720p limitation. I only zoom in occasionally but encode 640x360 for my iPhone anyway, just in case. I guess it only makes sense on an iPhone since the screen is so small.

In that case, 1024x574 would be ideal to get one to one pixel mapping. Any clue if 1024x768 is accepted for 4:3 content?

I wouldn't. You'll increase your file size upscaling SD 4:3 material to that. Now if it's really HD 4:3 material, then do so (although a lot of HD 4:3 is just upscaled SD anyway).

All movies made before the mid 50s are 4:3 and HD quality.
 
Having to re-encode my MKV & BR collection to MP4 pains me. Hopefully someone will develop a MKV player for the iPad.
 
It would be safe to start the "mass conversion" of your collection only after some experiment on the real thing to find the best settings. By then, you'd also might have "iPad" presets in the main encoding applications.

Considering a file encoded for iPhone through handbrake looks not to bad on a 46" screen I'd say it's safe to assume that it'll look fine on the ipads.

This is one of the challenges I'm currently facing. Trying to get the settings correct & having Handbrake not crash before it finishes. I normally use Slysoft to rip a BR movie to hard drive then use Ripbot to rip to MKV. Now I just have to make a habit of ripping to MP4 instead of MKV.

Watch some developers make a MKV player by the time I finish converting all my MKV's to MP4. :eek:
 
I know it's for competitive reasons and all, but it's absolutely infuriating Apple won't let MKVs. If they announced .MKV support as the only feature in 4.0 I would likely be happy enough.

With my luck, by the time they allow MKV, some other format will become wildly popular. For example, as soon as I had a device capable of playing DivX and Xvid hooked to my TV, some knucklehead decided we all need to jump to MKV.
 
In Handbrake, the Picture settings (Shift+Command+P) allows you to set the exact resolution you want. I do this when ripping BD for Apple TV, which (thankfully) allows the same resolution as iPad.

Obviously no one knows yet, but unless and until there is an iPad preset in HB, I would use the iPhone preset, but then tweak the Picture settings (you're not going to need 5.1 surround sound etc.).

When ripping for ATV, after selecting the preset, I open the Picture settings screen, change the Anamorphic setting to "None", the "Keep Aspect Ratio" box should automatically get checked at this point, then set the resolution to 1280 x whatever. It'll never be more than 1280 x 720, and for cinema-wide movies will be more like 1280 x 538 (IIRC). Obviously this is only necessary for BD rips as regular DVD isn't high-def.

I expect that the iPad will be fine with this resolution, and I'm hoping that it'll play my existing ATV-style rips without me having to encode another version. I typically have two versions of each movie, one HD for ATV and one encoded specifically for my iPhone. I don't know if iTunes will be able to "nest" a third version of a movie for iPad, and I really don't want to be tripling up on encoding and storage space.

I use MakeMKV to rip BD, and then Handbrake to encode to mp4. So far, "Elf" is the only movie (out of dozens) that has failed to rip with MakeMKV, and successfully ripped movies have all been encoded in Handbrake. The only issue is that, on occasion, the resultant mp4 file from Handbrake is too big for my Apple TV (4+gb). Even then, that simply requires a re-encoding with the target file size set to 4gb.
 
I tried to convert a plain old DVD and got the size 720x384 in Handbrake. Do you guys think that res is good?
 
I wonder if the video size even matters. All that might matter is the bitrate, which will be a max of 2.5 Mbps.
 
Just a quick note that I've been able to play 1080p video on my iPad using either GoodReader or Air Sharing. Once you get the higher resolution files onto the iPad it can play even high-bit-rate 1080p (i.e. 30fps, 1920x1080 with bit rates of over 8Mbps).

However, these files can't be played with the iPad's Video player since iTunes won't allow you to sync any content that exceeds Apple's stated limits.

wonderful, but i dont see that as beneficial if you cant export it to a TV screen (or similar) that can actually benefit from the resolution increases and bitrate enhancements.

at those rates, even on a 64GB model you could only fix 4-5 movies on the ipad. :(

Going to give this a try this afternoon with GoodReader.
