I ran into this today. I shot a video, edited it in iMovie (on the phone) and saved it out in 1080p to the camera roll (because iMovie was puking trying to post directly to Youtube for some reason). From the camera roll I was able to upload it to Youtube and chose the HD setting, but in it's posted form on YouTube's site it only lets you view it in up to 720p. Not sure what's up.
when i upload a vid to youtube in landscape, it only gets to 720, but when i record and upload in portrait it get the 1080.
Can i get 1080 from a landscape vid???
I assume you're referring to the iPhone 4.
Consider that 720p (16:9) is 1280*720, which your iPhone shoots in. When your iPhone is portrait the resolution is 720 (wide) by 1280 tall. 1280 pixels tall is more than 720 pixels tall, so your video is beyond the bounds of 720p in height.
1080p (16:9) is 1920*1080, which allows more vertical resolution for your image of height 1280.
You can't shoot 1080p portrait because the resolution is the same for both, you're just kind of "transforming" it when you rotate the sensor.
Hopefully that makes sense.
If you upload from the phone the video is compressed to 720P. If you transfer the video to your computer via USB with iPhoto then the video will be 1080P. I was up for hours last night messing with this.
Thanks for the response. That's help, but it's disappointing (I'm guessing you felt the same). So in the middle of all this "getting away from PC dependency" with cloud sync, backups, updates from the phone, untethered sync, etc. we can't output using the full capabilities without....yep, a computer. D'oh!!
Thanks again for the response.
I have a similar line of questioning for TV. It seems like if I use Airplay to play 1080p videos from my iPhone 4S to my Apple TV, I will only get 720p output.
