IPhone 4 Video Mode image is larger than camera mode. Normal or Bad?

Hey there, im using an iphone 4 White. I start to browse through my device.
But something caught my eyes. Which is the video Mode.
So this how it goes, when i view my device in camera mode everything is normal.
But i switch to video mode, the image became large. Its like the device automatically zoom in..
Becaus of this, each time im taking a video, i need to take a step back..
So what im asking now is, is there any chances that it can be fix... For what i know, when im using my iphone 3gs everything works fine.
So Do help me find a solution to my curiousity.. Thank You.

I'll try to give you an explanation; I hope it's clear.
When taking a photo the iphone uses the full camera sensor (2592 pixels by 1936 pixels).
Which gets the full wide view of the lens.
In order to record video the iphone appears to only use the middle of the sensor to record (1280 pixels by 720 pixels); and it ignores the pixels around it.
Which then cuts down the field of view by almost half; and that looks like it has zoomed in.
Have a look at my diagram, red is the photo mode, blue is video mode:
This is a limitation of the hardware, as it might not get faster data from the sensor to allow the camera to shoot higher resolution, or a wider field of view.
It actually allows the iphone camera to not have as apparent aliasing issues, but certainly lowers the field of view.
Other cameras can "skip" lines to record video.
This allows for much wider field of view, but it does introduce pronounced aliasing issues (as information is "lost" inbetween the lines).
So this probably won't be fixed in the iPhone 4; although video was "added" to the older iphones by developers, it isn't likely to be that easy on the iphone4.
But you will probably hear of a higher pixel count camera in the iPhone 5, and it will possibly be able to take higher resolution video; but in a similar way it will probably only use part of the sensor.
I hope this makes sense?

IPhone 6 video too dark (much darker than iPhone 5 video)

Anyone else noticed this??
Also manual exposure control doesn't work for me when in video mode, when i move those on screen controls nothing changes whereas when i move them in photo mode pictures become either brighter or darker.

iPhone 6 plus video is dark compared to the pictures
Just a note that there was a topic about this started on October 2, 2014. I copied the subject line of that topic above. As of today that topic has had 11,946 views and 49 replies. Although this topic is about iPhone 6 and not iPhone 6 PLUS I'd suggest to any potential contributors to this topic consider posting to the earlier one that has more views. In any case I would encourage anyone reading this who has the same issue to post SOMEWHERE about it on this forum. If you are wondering what the fix is, there isn't one and if you get a replacement iPhone you will have the same issue as bendyy did above.
But please consider moving this conversation over to iPhone 6 plus video is dark compared to the pictures which was posted on Oct 2, 2014 by siddsv

Why is Keynote storing images 20x larger than the original file size upon import?

In Keynote, I'll add a 150KB PNG image to a slide and the 500KB presentation goes to 3.7MB... a more than 3MB increase. I'm trying to troubleshoot large file sizes as a simple deck takes up 50-100MB on disk. Anyone know what is going on to make the file 20x larger once added to Keynote? And how I can keep the file size down? The 'Reduce File Size' option is worthless in this case... offering a less than 10% reduction on the earlier 20x amplification. Thanks

Yes converting an existing version 5 file in to Keynote 6 does many strange things. Any existing version 5 files I have, I continue to edit in 5. When starting a new presentation, I can use 6 without many problems at all.
I provided the files to replicate the issue to Apple support and never heard back.
Apple do not provide feedback to users on issues, they only request information from users.

Why are still images importing larger than their size?

Per instructions in a thread I had here last week, I created all of my DVD still images at 720 x 534 pixels for Premiere Pro CS5.5. But when they are brought into a DVCPRO50 NTSC Standard sequence, they are being heavily clipped. The original in one example is this:
But when that same images is brought into PP, it is sized up like this:
It's still proportionally correct, but a lot of the top and bottom of the image are gone. The encoded MPEG-2 sequence and disk I've done as a test display just like that.
Why is PP doing this, and how can I get it to use images built to the correct size to be used 1:1 in a sequence instead of being scaled to about 115% of size? Hate to compare this way, but this was never an issue with Final Cut Pro, which I'm switching from. Stills created to the size FCP needed of 720 x 540 displayed and finished exactly as they were made in Photoshop. The only image area lost was the normal bit of overscanning DVDs display at on your TV.

I guess I don't understand. This is an excerpt from the CS help. This seems to be inconsistent with what the last two posts said.
Composition settings presets for square-pixel equivalents of standard definition formats have changed as follows:

Alpha channel video makes for a larger-than-target bitrate flv

I'm looking for some information regarding the final bitrate of alpha channel encoded video. We are producing transparent flvs. When targeting a number, say 200kbps, in Adobe Media Encoder, the final encoded flvs has a bitrate of sometimes as high as 350kbps or 400kbps. And that's just the video.
When I encode without the alpha channel with final flv video bitrate is basically exactly what I targeted.
I'm assuming GSpot and MediaInfo to look at the final flvs.
Why doesn't Media Encoder produce and flv at the target bitrate? Why the higher bitrate? Is there a way to set the final target for an flv? Is there better software?
Thanks,

Since the lounge is for non-technical discussions, you need to start at

I will GUESS you are using some flavor of Premiere Pro, so that is most likely where you should post

Export images come larger than the original

The other night I did an event shoot and imported JPG photos into Aperture. The file size on average was about 1.5mb/photo, but when I exported the photos, they came out to be like 5.7mb/photo or greater. I couldn't understand why the exporting processing was taking so long, and I discovered it was because the files were too large. This seems to be happening only in Aperture in my laptop. It doesn't seem to happen with Aperture on my Mac Pro. Anyone else experience this problem? Solution?

I can't recall if it defaults to 10 or 12. 12 makes pretty large files, as you've seen
As to "enough" for your photos -- how are you printing? This only affects saved JPEGs. If you're creating files and sending them to a web site for printing... they'll still probably be good enough at 8x10. The real issue is repeatedly re-saving JPEGs over themselves... each time you do a little more quality is lost (JPEG is a "lossy" compression so each time you re-save you lose some more). A single save is probably just fine. But I wouldn't save at quality 9 and then save over it again and again after I'd thrown out my original.

Photoshop is consistently printing my images slightly larger than specified?

Photoshop CS6 on an iMac with OS 10.9.5 printing to an Epson 7900.
Epson say that its not a printer issue. Anyone know where I should be looking to resolve this issue?

"Scale to fit media" should not be checked.
If your printer is printing properly on apps outside Photoshop, usually a reset of Preferences will fix it.
Hold down cmd-opt-shift and start Photoshop, agree to the reset.

IMac 5.5, OS 10.6.8 During startup, the screen aspect changes so that the image is larger than the screen; I have to scroll to find top, bottom, left, right extremes.

Screen display aspect ration suddenly changed while I was online so that I have to scroll to see the edges of the display: up, down, left, right. I rebooted the computer and the problem persists.

System Preferences->Displays->Display and reset resolution to desired size. Don't know of anything that would change that except possibly a failing graphics card.

Navigate an image that is larger than the stage?

Hello, I would like some assistance getting this to work. I'm not even sure if its possible, but I will be eternally grateful for an answer.
I would like to have an image much larger than the stage, with little buttons all over it that play a MC when moused over. When the mouse reaches the edge of the screen, I want it to scroll so that the viewer can explore the whole image.
In short, its a map with destinations, and on mouse over the destinations play a MC. I'd like the viewer to be able to "explore" the map with the mouse.
It seems simple, is there a good way to do it?
Also, once it is done, is there a way to begin with the entire image shown, but then have it tween to its final (Very large) size, without breaking that functionality.
Thank you so much. This is for a class project and I'm trying to "go above and beyond" but, its a little to beyond for me.

To make the image move, based on the mouse position you might do something like this:
addEventListener(Event.ENTER_FRAME, checkMouse);
function checkMouse(e:Event):void
     if(mouseX > 500){
          myImage.x -= 1;
     if(mouseY < 100){
          myImage.y += 1;
That's just a simple example. You'll need to check the bottom and left too... and you'll need to stop your image from moving past its edges:
if(myImage.x + myImage.width < theRightEdge){
     myImage.x = theRightEdge - myImage.width;
to keep it from going too far left...
I would also suggest using TweenLite to do your tweening. You can simply google TweenLite to find it.

MDM Not Able To Load Linux Kernel Images Larger Than 32MB?

Hi All,
I've been building linux initramfs images for use with a Kintex7 (KC705) running a MicroBlaze processor and have been running into an issue with loading the images using the MicroBlaze Debug Module. It seems the system won’t boot if the image is larger than 32 MB. Unfortunately, my use case requires all application code to be contained in the kernel image and I won't have local non-volatile to boot from.
Some key factors:
Petalinux 2014.4
FPGA image built using Vivado 2014.4 on Windows 7
1GB RAM on KC705
Loading images using TCL script on XMD on Windows 7
As an example, I built an image that would fit within the 32 byte "limit" and booted it with no issues:

I've also tried the same test with a plain Petalinux image and none of my application code or other customizations to rule out a configuration issue. Additionally, I've tried updating Vivado to 2015.2 and rebuilding the FPGA image, also with no success.
FYI, here is the TCL script used to load the images:
fpga -f system_top.bit
connect mb mdm
after 2000
dow simpleImage.mb
con
disconnect 0
I've done a bunch of research on initramfs and haven't seen anything that points to a size limit (except as it relates to RAM size). Anyone have an idea what's going on?
Thanks!
-Nick

Some additional information:
When the system fails to boot, there is no error message displayed either on the XMD window or the linux console output. The console remains blank.
I have been able to add random files to the ramdisk that do not push the size over the 32MB boundary and the system successfully boots.

Can I print a image larger than 4x6 directly from iPad's photo application to a HP Air Print printer without a additional app?

It depends upon the capabilities of your printer. If you have an HP printer with a photo tray then the Photo app will print to whatever size you load in to that tray.
There's some more information here:
Using AirPrint to Print Various Photo Sizes
With other printers the user is given a choice from the printer's loaded paper sizes. You can see an example of that here:

Video exposure not working in all 3 video modes new iphone 6 Plus ios 8.1

Bug 1. In video mode, exposure does not automatically brighten in darkly lit areas - then when you touch the screen to focus and try and use the sun slider for upping or lowering the exposure, you have to swipe it many, many times to go a short distance, then IT ONLY WORKS TO DARKEN THE EXPOSURE, IT DOES NOT LIGHTEN IT IN ALL 3 VIDEO MODES. It works fine in Photo mode. Go to this video at :54 to see it working properly: https://www.youtube.com/watch?v=tehcNa3ecs4#t=75
Bug 2: Slo-Motion videos will play back on computers in slow motion ONLY if the base frame rate is set to 60 fps and the Slo-mo speed is set to 240fps. With any other settings the computer (both win and mac) play the video back at full speed.
Especially with bug 1, can any of you check your phone to see if sliding your finger up will brighten the image while in any of the 3 video modes?

Hi,
I'm having also having game sound issues the game music and sounds just go completely quiet in iOS 8.1. Sometimes it'll just be completely quiet and others I'll have game music and sounds and partway through the game I'll lose audio. It's not the side lock/mute button either which I checked.
It's happening in two different games: Shadowgun:Deadzone and Modern Combat 5.
I have that side button above the volume set to toggle mute and I tried changing it to lock rotation instead to see if that made a difference which it did not. I have to kill the game and relaunch it to get the game audio working again.

IPhone 5 created a backup larger than the phones capacity (16GB) and now I can't get anything back onto my phone after Restoring it!

I had a few storage issues to start with, I basically deleted everything in my phone (media, messages, notes, calanders, apps etc) and my phone still said it was at capacity. The more I deleted the less I could put on there. So I took it the the Apple Store where the manager told me to do a Restore. I did this, then was unable to put the backup straight back onto my phone as it said there was not enough free space (it was empty!), I then called Apple Support who instructed me on how to view the size of the backup and it turned out to be 16.32GB (.32GB larger than the iPhones's capacity) but were unable to give me any useful tips! I downloaded a backup extractor but have no idea how to use it! Please help me

why should I do that?

Compressor setting so it won't output a video larger than source?

Hello.
I am sending a whole library of videos (most Apple ProRes, but varrying video dimensions based on the project) through Compressor 4 and I'm having an issue where, for some of the videos (with smaller video dimensions), the settings I'm choosing result in the transcoded videos being larger (in terms of dimensions) than the source (ie. if the source is 720p, the resulting video is 1080p).
I am using the following two settings:
- HD for Apple Devices (5 Mbps)
- HD 1080p for Video Sharing
Example 1 - I fed a 640 x 360 (Apple ProRes) file into Compressor 4 and selected the "HD for Apple Devices (5 Mbps)" preset. The resulting transcoded video was larger than 640 x 360 (I can't remember the actual size anymore, sorry). There is no option available, that I can see, to modify the preset to NOT create a file larger than the source?
Example 2 - I fed a 720p (Apple Animation) file into Compressor 4 and selected the "HD 1080p for Video Sharing" preset. The resulting transcoded video was 1080p. I though because the preset is marked "Up to 1920 x 1080" it wouldn't go beyond 1080p (ie. scale down anything larger to 1080p), but also thought that it would maintain the source dimensions and not enlarge a 720p source to 1080p?
Maybe this is how Compressor is supposed to work (ie. making resulting videos larger than source), but I'm hoping there's a way to modify the presets to not do this "ie. an option to not create a video with dimensions larger than the source)? Is this possible?
Thanks,
Kristin.

Apple devices have a standard frame size they encode to, so yes, this is how it works.
