iPhone 4 vs iPod Touch 4 Comparison Videos

[QuarterSwede]

I seriously doubt it, see this. http://gizmodo.com/5634796/worlds-first-hdr-video-makes-me-weep-at-its-beauty The video looks unreal, and this was an experiment, I think if they shot a movie like this it could have a unique artistic look to it. Instead of the overuse of cheap color themes Movies use nowadays.

Apparently you skipped over this:

HDR (you mean tone mapping)-video:

I have not noticed any such issue with my camera on my iPhone 4, I have been nothing but totally amazed with the quality of video. ... I have yet to not be floored with the video quality.

Agreed. Every video I've taken has looked much better than the comparison here. None of my videos are that washed out. Mostly they have very good saturation and exposure. It is too bad that they look better on the iP4 than they do on my MacBook & Samsung HDTV though. That screen really is phenomenal (326ppi, LED backlit & 24bit color).

Yep, agreed. More stable and better handling of rolling shutter. It almost seems like that labels are wrongly positioned, it can't be this much better.

The iP4 is not that bad. If you have a reasonably steady hand you won't even see it shake as much as the iPod touch in the video. That guy has to be right handed. It's the only explanation for someone whose actually used one.

nope, you're wrong

lol. i love it. there must be a definitive correct vs incorrect. one is right and one is wrong.

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.

If you want a 'non-shaking camera', just run the footage through the stabilizer in iMovie. (The real one, not the iOS version.) You'll be amazed at the output. And better yet, it works with any movie you can import into iMovie.

To summarize, the only way to get "true" HDR images is through rendering that handles unlimited range lighting calculations, via HDR image sensors (RAW data from cameras is a small subset of HDR), or by combining multiple exposures into an HDR file format, such as EXR.

I don't disagree with anything you wrote above, but one can save an HDR jpg using xDepth.

It's awesome. It's compatible with any web browser or anything that can view jpg files, but if you bring an xdepth HDR jpg into photoshop and adjust the exposure, you can pull details out of shadows or bring imagery back into bright areas.

It's free. Download the plug and fool with it. It's a shame nobody has adopted this yet.

I can tell you that the iPod touch is terrible in anything less than almost perfect light. Artifacts everywhere on the screen. iPhone is sharper and if you adjust the settings, it can beat out the iPod touch every time when it comes to saturation and such.

 

[ed724]

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.

Maybe because the IP4 has more pixels to manipulate ?

OMG, would everyone quit complaining about the shaking of the iPhone 4; it's obvious that these tests were done at the same time and the iPhone was in his left hand while the iTouch was in his right, I'm willing to bet that he's right handed, and just had a steadier hand with the right. Although I will admit the colors did seem to pop a bit more on the iTouch, and that would just be a personal pref.

That's nonsense. Try doing a test for yourself. Being left or right handed has nothing to do with it. In terms of holding a steady hand it matters none.
I can easily see by some of the posts here that are saying the iPhone video is better that they are probably an iPhone 4 owner and can't stand the fact that the iPod shoots a better video from a contrast, color and steadiness standpoint. This is not to say that I am referring to you per say.

Hey that's pretty cool. I work with EXR files daily, but wasn't aware of Xdepth. Add another format to the list that can support "true" HDR data.

 

[freddiecable]

i second that

I thought the same thing.

 

[jamesryanbell]

I don't want Touch users to be bale to claim they have the same thing as an iPhone. That's good news.

Buy the best, or have the rest.

Indeed, I thought the iPod's video looked a bit smoother for multiple reasons. Less camera shake, smoother video. But what would cause the smoother video? It looked like the iPhone didn't capture a consistent framerate - it chopped a couple of times like the system had other things to do. Does the internal memory get fragmented or something?

Perhaps I can be swung by this generation of iPod after all.

I would side with others here who have said that the iPhone's stuttering is caused by the higher MP of the sensor. The iPod doesn't have to downscale the sensor data on the fly like the iPhone does.

 

[r.remer]

how can you know whats better?

how can we know what video is better without seeing the scene for are selves? i would say that the iphone4 video looks better but is it as accurate to the real thing. As the ipod touch 4 video may be a more accurate to the scene then the iphone 4.i would say the person who took the video would now best or someone who has done a comparison them selves not just some saying what video looks better.Im probably just talking crap.

 

[XciteMe]

I was JUST about to say the Touch's video looks better than the iPhone 4.... Which is weird... The contrast is more defined, it's less shaky, and it's a wider field of view.

Hm.

Tempted

I feel more tempted to buy an iPod touch 4 now. I may wait for things to settle a little more. I'm going to wait for the Incase slider design. Now the iPod touch display is better than previous generations, is it still a good idea to get a screen protector or is that going to distort the screen and look bad?

I think the videos are interesting. I believe we would have to see the landscape through our own eyes then come to conclusions.

 

[twoodcc]

the ipod touch had darker colors. is that better though?

 

[TheMBC]

Perhaps the person shooting the video just has a much more stabler right hand than they do a left hand?

Look, there is some serious misunderstanding about what "HDR" is and isn't. Let's clear up some stuff here.

What you are talking about is tone mapping. When you take 3 exposures and combine them, you're just tone mapping - bringing out visible range in various parts of the exposures. You're not generating an HDR image.

What you call "fake HDR" is an oxymoron - it doesn't exist. You can't pull out data that isn't in the image. All you're doing here is exaggerating what little information is already buried in the image. It has nothing to do with HDR.

The end result of "real HDR" is a high-dynamic-range image that can be edited with various HDR tools. It contains more range than can be displayed all at once on most display devices.

Since none of the sensors in any iDevice have a high dynamic range, and since no image generated by an iDevice is an HDR format, you can't get HDR from an iDevice, regardless of how many exposures you take.

Not that anyone will bother to read it, but here is more information:
http://en.wikipedia.org/wiki/High_dynamic_range_imaging

To summarize, the only way to get "true" HDR images is through rendering that handles unlimited range lighting calculations, via HDR image sensors (RAW data from cameras is a small subset of HDR), or by combining multiple exposures into an HDR file format, such as EXR.

Ah, yes, I don't disagree, but I would rather point out, that I was aware of the facts, and there does really seem to be disagreement on what can be called HDR and what can't. I must admit that I simplified things maybe too much.

Since I thought the subject was how to implement the same type of HDR-effect into video, as can be done on iPhone 4 with still images, I tried to think of the possibilities, rather than appropriate naming. Because on your terms, which are probably quite correct, Apple couldn't call the iPhone's HDR functionality HDR, as it combines multiple exposures, but not into an HDR file format. I would rather call this HDR anyway, because even though it's not actually in a HDR format, it is not simply tone mapping a single exposure, and in a consumer product, you are going to view it on a LDR display anyway, so the end result is the same, independent of the file format. I might have missed a point somewhere so, correct freely.

Anyway, what I called fake HDR, is not HDR at all, agreed, hence the word "fake" in it. A single exposure photo could be made into an HDR, if it was taken as a RAW image, right?

As for the problem with taking video with multiple exposures on a single sensor, yes that would be problematic if there was lot's of movement, and the frame rate wouldn't be high enough.

iphone 4

i think that the iphone 4 is definitely a winner what every anyone says. phone have a history with cameras, yet its not common to have a camera in a PMP. im happy with my iPhone 4 Camera as i can shoot decent quality still: the ipod touch camera can only shoot 0.7 MP stills
