Letemsvetemapplem.eu has posted a series of videos providing some direct comparisons between the iPhone 4 and 4th generation iPod Touch. The first one is a speed boot test between the iPad, iPhone 4, iPod Touch and iPhone 3GS. We're not sure if it shows very much, though the iPad booted the fastest of the bunch.

More interesting is the embedded (above) video showing the differences in the display angles between the iPhone 4 and the 4th generation iPod Touch. While the new iPod Touch does contain a retina display, it is not the same high quality display found in the iPhone 4. The iPhone 4 uses an IPS display which offers better viewing angles.

The site also provides a side-by-side comparison of the iPhone 4 and iPod touch taking video:

iPod Touch looks to shoot a much better video than the iPhone 4, IMO.

The iPhone 4 shoots are more accurate video of the actual light level.

Yeah, but have you seen how shaky it is on the iPhone 4?
Since it was released, I really hated the way the videos seems to be shaking.
I'm not asking for a steadicam, but the result is pretty lame if you'd ask me.
Of course, many people will say that this camera rocks and all, but you'll see, in a few years (if not next year) when this will be fixed and that everyone will want the new "non-shaking camera" on the new iPhone.
 
iPod's video looks better

The iPod's camera has a wider field of view (which is generally a good thing for this sort of device) and much better contrast. The iPhone's video looks a bit washed out.

I'd really like to see a low-light comparison.

I did say MY OPINION, just like your perception of the videos are YOUR OPINION. Nobody's right or wrong buddy. :p
 
More MP is not better for video, since you have to do binning or pixel skipping. For example, the RED one camera, that can do 4K video, only has a ~10 MP sensor.
 
At least in this sample I prefer the video quality of the iPod touch over the iPhone 4.

I've had an iPhone 4 since launch and still haven't taken any videos, that's what my DSLR is for!
 
Agreed, the Touch's video is clearly better in this test.

I had noticed the breaking up/jumping about on some other iPhone4 video's

Wonder why it does that?

Almost look like the CPU or GPU is struggling to keep up with the camera's movement where the touch does not have that problem.

Would be interested to hear the technical reasons why the iPhone4 is having these video problems.

Rolling shutter or line scanning.

Since the sensor on the iPhone has more pixels, its more affected by it I would assume.
 
iPhone 4 Hands down I have both new iPhone 4 and the new Touch and to be honest I'm a little disapointed in the touch but still like both just love the iPhone a little more
 
The touch looks to have some kind of stabilization thing going on with the video. Much less jerky than the ip4.
 
Could Apple build HDR support into the video cameras too, or is it solely a photo thing?

I did think the iPod touch video looked better, but that video only showed one setting, I’d like to see more.
 
Well the iPod video has more contrast and saturation...better? Not for me...I look at things like the detail in the shadows or dark areas...that information is lost...so the dark areas are just blobs...the fact that the iPhone video has plenty of contrast and saturation, and its EASY to add more (not less) makes it better for my purposes. I get DETAIL in the dark areas, not just in the brighter areas...The iPod does have a wider lens so it gets more in the image at one time...thats nice, but means you have to use the zoom more...not so nice..Pros and cons of each...both are pretty good for portable NON-camera devices.
 
When you're holding it in your hand, does viewing angle really matter? Also the difference in video quality can probably be matched with a few tweaks of the settings. They have identical cameras don't they?

Theoretically yes, but it would either require dropping the fps to about one third, or extreme processing power. Or both.

A real HDR is usually made of three or more exposures, so the videocamera would have to take three differently exposed frames and combine them into one HDR-frame. This would drop the fps of the video to around one third, which would made the video stuttering, plus it would need quite much processing power. Probably more than the iPhone has if the processing were to be done in real time.

A "fake HDR", some call them FHDR, single-exposure HDR or whatever, could be used as well. The iPhone/iPod should capture the video normally, but then use tone mapping methods to correct exposure in each frame, which would need, again, quite much processing power. It could be possible, but I don't think it'll look good, though.

Sorry, they don't. The iPhone has a 5MP sensor, the iPod a ~0,7MP one.

I agree, the Touch's contrast and colour tone looked much better. But...

I'd really like to see a comparison of skin tones.

Looks like the iPod touch uses the entire sensor area for video while the iPhone 4 uses only a part of the sensor. That means the iPhone also uses only a part of the lens area for video, which means that all dirt, grease and flaws in the lens will be magnified. I would think this plays a big role in the iphone's worse flare problem as well as camera shake (more tele, more shake).

The iPhone camera is designed for still images, the iPod's camera is clearly designed for video.

Another thing to consider is that a 'good' HDR photo composition needs all of the shots to be identical; if there's any movement between the separate images you get 'ghosts'. I would think that shooting HDR video in this way, where the 2 secondary frames would be marginally different from the main frame would lead to blurred edges on moving objects. I think the only way to shoot HDR video is to take the three frames simultaneously, which needs three different sensors viewing exactly the same scene.
