A Variety of iPhone 4S High Definition Sample Videos

Anybody seen/know any concrete specs of Apple's choices for the 1080p file?

I downloaded several from Vimeo. Vimeo allows you to download the uploaded file if the poster lets you. I wasn't satisfied they were all uploaded without going through some process, but two looked raw and gave me the following information.

Video: AVC, VBR up to 24.0Mbps, Baseline@L4.1, Progressive, Color Space: YUV, Bit depth: 8, Frame rates: 24.424 and 29.936 (different parts of the world, Japan, USA).
Audio: AAC, 44.1KHz, bit rate 64.0 Kbps​

I used Mediainfo Mac to check the specs.
 
Probably electronic image stabilization which works with the data on the sensor.

Versus the much more expensive optical image stabilization like on the Canon L lenses, where the optical elements in the lens move to adjust for shake.

By the way: very astonishing that this footage comes from a phone.

10 years ago a semi-pro video camera wouldn't have been able to record such quality.
 
Wow.. thanks to MacRumors for linking to my Canon 500D/T1i comparison video.

To answer a few questions... the Canon video was shot using the standard 18-55mm kit lens, and it's outside a Tube station in London.

In fairness, you can get video out of that camera that looks a lot better. I created it as a quick comparison for a website feature and the whole point was to take video 'like a normal person would' - ie stick the kit lens on a DSLR and hit record in movie mode.

The video comparison was just part of a whole camera comparison I was doing yesterday morning so I won't pretend it was scientific or thorough!

xStep, thanks for finding that. That's pretty good on the Mbps and not a surprise on the fps. Audio Kbps is not so good, but hopefully that was just for the samples you found (I would think Apple wouldn't arbitrarily choose only 64 Kbps as a cap).

I'd love to see Apple just completely max out the 1080p specs so that they are truly head-to-head with BD specs. The above is impressive- especially for such a compact device where the video is just a bonus feature- but I still think the best way to really beat down the "bag of hurt" is to at least get toe-to-toe with it on picture & sound quality.

...because when we're trying to imagine an advantage for 720p like 60fps, we can't imagine the same being applied to 1080p? As in 1080p 60fps?

If this is another 720p is better than 1080p because "good" 720p is better than "bad" 1080p or similar, please note: the BIG change now is that Apple- yes Apple- has officially endorsed 1080p in an Apple product. I know historically 1080p had to be a terrible choice because Apple seemed to strongly favor 720p in all things... but that's over now. Apple is driving the train that has left that station. Expect more 1080p-capable Apple products to follow soon.

If you personally love 720p, this will let you shoot video at a higher resolution and then you can edit it (down convert it from 1920 x 1080 video to 1280 x 720) down to 720p. That will still make it possible for you to get what you love while also allowing those that want the extra resolution to get what they want too.

Anybody seen/know any concrete specs of Apple's choices for the 1080p file?

Mbps?
frame rate?
Etc.

What technical tradeoffs- if any- has Apple chosen for it's incarnation of 1080p?

It's unlikely that a small camera on the cheap side can do 1080p 60FPS. Since I like 60Hz and many consumer cameras can do 720p 60FPS I was asking if the iPhone can do that as well.

No this is not a 720p vs 1080p post. Don't know where you get that from. But thanks for the lecture although it didn't answer the question at hand. :rolleyes:
 
If someone could get me some Concert footage in the dark with the stage lit up I would appreciate it.

Here's the info from a video I took today. The upload to YouTube was only at 720p. The stats on the source file (from MPEGStreamClip) show the following:

Duration: 0:01:24
Data Size: 242.68 MB
Bit Rate: 24.00 Mbps

Video Tracks:
H.264, 1920 × 1080, 29.963 fps, 23.93 Mbps

Audio Tracks:
MPEG-4 Audio mono, 44.1 kHz, 63 kbps

He got that from this other thread where on post #10 Nateo200 says; "good 720 is miles better than bad or even ok 1080". I guess HobeSoundDarryl got a little sensitive on the subject. ;)

Apple's camera app doesn't seem to have any preference or live settings to change things like resolution and frame rate.

Someone could create their own camera app to allow different frame rates and resolution and other things, but the firmware and frameworks do limit some settings. For instance, I tried setting up my iPod touch to do 60fps on input, but the firmware or framework limits it to 30fps tops. I don't have an iPhone 4S to test, but I wouldn't be surprised if it has the same limit.

Thanks for the confirmation.

N8 has a huge (no it's HUGE) advantage over any other phone (4S, GS2 all included). It has a mammoth sensor for a mobile phone. 1/1.83 inch is about 75% more than 4S/GS2/Arc sensor size.
Click to expand...

Yes the N8 was just a weird product. It had one of the fastest GPUs and the best camera sensor in a phone and yet combined those with the slowest CPU by far and the smallest screen in any modern high-end touch smartphone. I'm a former Nokia user and that narrow 3.5" widescreen display was a nightmare for onscreen keyboard usage.(iPhone has a 3.5" screen, but it's wider sideways so typing is less of a problem) Then there's Symbian...

I liked that someone tried to go all out on a camera but looking back, the cost of doing something like the N8 is probably just too much considering the high component prices and the extra thickness of the phone. But the build quality of the N8 was quite exemplary and pity that no one in the Android world has the ability to produce something like that. It remains to be seen how successful their Windows Phone 7 will be though. So far WP7 has been a sales disaster.

For those with iPhone 4S, how well do it focus during video recording?
 
The video in the original post does look pretty good (for a phone). But then we get to see some other videos shot with iPhone 4S that look rather awful. Here is an example. Some guy compared 1080p videos shot with 4S and Samsung Galaxy S2. They show the cars on the road under bright Sun and both videos look bad. There is no clear advantage to any one of them although I think that 4S version shows more compression.

I think the frame rate difference may be due to lighting. The Japan video was at night. I know the Apple camera app slows down the video to 24fps in low light. It is a feature to collect more photons. I thought I knew a way to force 24fps, but further testing came up empty when dealing with good lighting.

Just found this "Foo Floyd - Shot with iPhone 4S" on Vimeo.
 
This was probably already linked in this thread, but I didn't see it.

Pretty darn impressive. It won't be replacing DSLRs for more serious work, but the quality seems excellent and I'll be getting one :D

Here is a iPhone 4S / Canon 5d MKII($2,500) Side by Side Comparison.

Wow, iPhone 4S kicks butt!!!

Canon is a DSLR. The 2.5K you pay is for getting great still pictures not the video. It happens to produce good video too but the main positive there is the ability to use Canon lenses. The digital processor in this camera is actually pretty old (more than 2 years old). Technology progresses very fast. The more interesting comparison for video quality would be between iPhone 4S and a P&S camera like Nikon Coolpix P300 ($250). That is exactly what PCWrold just did and guess what - Nikon came on top in both video and still pictures category. BTW, Samsung Galaxy SII scored higher than iPhone 4S in both categories too. iPhone 4S did better than iPhone 4 though.
So, using your terminology, cheap P&S cameras still kick smart phone butts for stills and video. :eek:
