Apple unveils refreshed iPhone 4S

AppId is over the quota
AppId is over the quota
4 October 2011 Last updated at 23:38 GMT Rory Cellan-Jones looks at Apple's new iPhone 4S

Apple has unveiled the latest iteration in its iPhone range, but there was no sign of the widely rumoured iPhone 5.

The iPhone 4S, as the model will be known, boasts an improved camera and significantly extended battery life.

It will run the latest iOS5 operating system, which is set for release on 12 October.

The event was the first major announcement for new boss Tim Cook who took over from Steve Jobs in August.

The iPhone 4S, which will go on sale on 14 October, will be available in 16GB, 32GB and 64GB models - in both black and white.

It has the same look and feel as the existing iPhone 4 which was launched 15 months ago.

However, Apple said that updates to iOS meant the phone would boast some "200 new features".

Continue reading the main story Shares in Apple fell by almost 5% within minutes of the eagerly anticipated launch, with analysts saying that investors and Apple fans had expected the latest version to be a more radical improvement over its predecessor.

However, the company's shares later regained most of their losses to close down just 0.6%, albeit underperforming the NASDAQ index as a whole.

Voice control

Among the additions is an "intelligent assistant" that allows users to ask questions aloud and receive detailed answers back.

Siri, which began life as a third-party app, was purchased by Apple in 2010 but has yet to appear within its software.

Luke Peters, editor of gadget magazine T3, said that the software announcements would do just enough to keep Apple fans interested in the face of strong challenges from rival smartphone manufacturers.

You could sense a great wave of disappointment rolling through the Apple community.

Why rush out and buy the new, new thing if it looks just like that old phone that's been around for more than a year?

"Some people were looking for a brand new phone and they haven't got that today, so some will be disappointed," he told BBC News.

"But with the update to iOS5 and Siri that could be enough to sway people to make the investment."

Disappointment

Other industry watchers were less charitable about the iPhone refresh, and the non-appearance of the iPhone 5.

Gareth Beavis, phones editor at TechRadar said that the new hardware would leave many people underwhelmed.

"It was quite disappointing. I think there is going to be a lot of anger from users expecting something big bold and quite exciting after a long time of waiting from the iPhone 4.

"People will buy this in their droves, but Apple has missed a trick by just releasing the exact same phone again with marginally upgraded specs."

Details of the new phone were unveiled by Apple's Philip Schiller

For Apple's new chief executive, the event was as much about making a statement about his leadership as it was new products.

Tim Cook had previously acted as interim boss, looking after the company while Steve Jobs was on sick leave.

Unlike his charismatic predecessor, Mr Cook left the biggest announcement of Tuesday's event to a colleague - marketing boss Phil Schiller.

"Maybe he wants to bring other people to the forefront by letting others speak on his behalf," said Gregory Roekens, chief technology officer at PR firm Wunderman.

"But in terms of style, it was underwhelming. People were expecting iPhone 5, but instead it's almost fixing the weaknesses the previous phones had.

"It will be interesting to see how people react to that."

Apple Motion 5 review

Somewhere between editing video and designing full blown motion graphics, there are countless jobs that require making things move. It may be making titles, handling transitions, moving around video and imagery in two dimensional and three dimensional scenes, masking, compositing or generally arranging assets for purposes of utility or eye candy.

From its first release, Apple's Motion has aimed squarely at this type of activity. It is neither unique in that regard, nor does it do more than other rival tools. Instead, it promises to perform these tasks more quickly and with less effort. In its latest release, coming alongside Final Cut Pro X (FCP X), it sports a new look, expanded keying and parameter control, and a new under-the-hood architecture for greater performance. It also boasts new capabilities as a Final Cut companion. And then there's the price.

So, is Motion 5 a must-have addon for the new Final Cut, or even as a complement to rival editors or previous versions?

Motion, like FCP X, includes changes both visible and under-the-hood. The engine, now rewritten in Cocoa, incorporates OpenCL support for accelerating computation on compatible graphics cards, 64-bit architecture for optimised computation and access to greater memory resources, and support for Grand Central Dispatch multithreading technologies, all of which combine to help you squeeze the most out of your available hardware. As with FCP X and Compressor 4, there's also support for ColorSync colour management, and a shared render engine. These changes cover the whole tool, from plugins to effects to rendering.

More visible are other subtle but significant enhancements to functionality and control. You can now take advantage of resolution independence, ideal for targeting multiple formats. You can combine parameters into rigs to consolidate live control of your compositions, and then publish those controls to smart templates and FCP X. With Final Cut integration, it's possible to produce transitions, titles and generators that editors can reuse in Final Cut, especially useful for producing consistent in-house templates. On the compositing side, Apple has added greatly improved chroma keying.

Finally, as with FCP X, Motion 5 has also gotten a shiny interface remake. Motion's transformation, though, is far less radical. Aesthetic adjustments aside, it mainly serves to consolidate settings into panes. Users of previous versions will likely find everything within a couple of minutes, and Motion has never been more usable on a lower resolution laptop display.

The natural impulse is to compare Motion to other tools, like Adobe's?After Effects, that produce motion graphics and add dynamic visuals to video. However, Motion is a different kind of motion graphics program, one that emphasises playing with parameters live and in real time. The idea is not to choreograph elaborate, planned out visuals and then see how they look, but to constantly experiment and tweak as the motion plays.

Wrap your head around the workflow, and Motion is, above all else, quick to use.

First drop in some media: Motion supports PDF, still images, video and Photoshop PSD with layers, though not EPS (Encapsulated PostScript). It supports PDF import, but Motion retains its own independent crop settings, so you can't simply crop a PDF externally.

Next, hit the play button. You'll likely want to leave everything in Motion looping all the time so you can see immediate results. Finally, add filters, generators (covering a range of visual sources) and movement behaviours, and watch as your composition updates in real time.

The new keyer chroma key filter is a real joy, far beyond what you'd expect as a bundled freebie. Drop the filter onto your footage, and compositing to a colour (such as a green screen) is effective immediately. To adjust the effect, there are basic but effective and understandable controls for tuning colour sampling for the background and edges, all of which nicely complement Motion's matte and 2D and 3D compositing tools.

Motion is also an effective basic 3D compositor, with controls for setting layers in three dimensional space and adding lighting and camera controls. 3D compositing is powerful, though if you need native support for stereoscopic 3D output, you'll need to look elsewhere. Also, one potential downside of the reliance on the GPU is you can get different results on different hardware. The only bugs I encountered were a couple of non-reproducible Nvidia GPU-related crashes.

As before, Apple also bundles a great deal of functionality and content in the box. You get sophisticated, easy to use match move and motion analysis and stabilisation features, inherited from Apple's high-end (and now defunct) Shake product. 3D compositing includes the ability to quickly rig up a scene with depth, then add movement simply by dragging and dropping simple motion behaviours. There's a powerful, intuitive replicator and particle generator that with After Effects, for instance, would require a third party addon. Apple has also bundled a vast library of preset content.

Advanced After Effects users will often (rightfully) praise the Expression scripting language, which allows users open-ended extensibility by enabling advanced motion behaviours in code. Motion's approach is visual rather than textual, but it should not be discounted. By combining behaviours, generators and filters graphically, spreading them out across the timeline and adjusting parameters on the fly, it's possible to build more complex structures.

As before any slider anywhere, from a crop control in an image to the amount of a filter blur, can be manipulated or controlled with keyframes, audio and even MIDI controllers. Most audio control hardware transmits standard MIDI messages, so you could, for instance, assign the level of an effect to a knob or key on a keyboard.

What Apple has added to Motion 5 is the ability to encapsulate selected controls into dynamic parameter rigs, controlling many elements at one time. That's useful both in the context of Motion itself, and as a means of exporting smart templates and interactive visual materials to FCP X.

If Motion's depth lies in lots of live parameter control, rigging combines related parameters into groups that can be controlled all at once, greatly simplifying access to that power. For instance, you might modify the display of a video in a 3D composition, adjusting the position of the camera rotating around it, changing its position in space, and altering a colour balance filter on the video. With the rig, you could combine those elements and control them together, which could for instance greatly simplify adjusting the timing of all those elements against another video or a sound bed. It's useful enough that you really don't need FCP X to make this feature alone worth the upgrade.

To create a rig, you first select the parameters you wish to control, then assign them one by one to a master rig that will control all of them. The rig is composed of widgets, either a popup, checkbox or slider, which provide both an interface for exported templates published to Final Cut and a means of controlling parameters within Motion itself. You can even nest widgets within other widgets. As with other Motion parameters, you can assign MIDI and audio control or behaviours like Wriggle and Random. The result is a kind of generative, modular system for producing dynamic motion effects without coding.

As with any graphical system, sometimes this makes tasks harder or less direct than with code, and sometimes it makes things a great deal more understandable. If you have experience with something like After Effects Expressions however, you may find some of these differences refreshing and complementary, and that your background in Expression code translates well to understanding how to make the most of this feature.

Motion's plugin architecture isn't yet as broad as After Effect's ecosystem, but this appears set to change, especially with Motion's aggressive pricing and expanded FxPlug2 SDK. Noise Industries, Genarts and Ripple Training have shipped Motion 5 plugins already, and other vendors are committed to shipping updated plugins.

Motion makes a natural companion to FCP X, either for editors who need to quickly generate assets for Final Cut, or dedicated motion graphics designers wishing to collaborate with editors using Final Cut.

Motion is capable of exporting four kinds of files back to the latest release of Final Cut: Transitions make use of Motion's various eye candy tools for slick edits between materials, generators produce graphics dynamically (such as particle effects), titles allow use of animated text with typographical controls and RTF file import and filters allow combinations of image and video-processing effects.

A natural workflow, then, would be to jump into Motion to create some quick titles, export back to FCP X, and then make adjustments as needed from within the Final Cut timeline. This is where the use of rigs can really shine: Motion supports the creation of dynamic, intelligent templates. You can choose not only which parameters to make visible in Final Cut, but even how you wish to define ranges, drop zones for adding standard assets and locked-down parameters.

For an individual user, this means you can start your work in Motion, then adjust it in real time in Final Cut to finish the job, without ever re-rendering or switching apps. For organisations with multiple users of FCP X, it has even greater utility, since it means that even novice editors can define easy to use house templates with strict parameters for everything from video effects to titles. On the Final Cut side, your content appears in exactly the way that the presets Apple ships do. In fact, those presets are likewise created entirely in Motion.

In the absence of specific integration features, in order to process a video clip from Final Cut Pro in Motion, you would choose Reveal in Finder, operate directly on the video clip, export the results and re-import and replace the clip. In other words, you do manually what automatic round-trip workflows previously did. The upshot is that for those not interested in the slick new template features, it really doesn't matter whether you're using FCP X or another editor.

This workflow does the job too, and given some of the complexities of fancier integration, might even be preferable to some users. But it means there's some room for improvement, particularly for editors who want to switch frequently between the two tools for genuine, bi-directional integration. The workaround to preserving audio is to export a self-contained Movie and re-import as an event in Final Cut Pro.

The integration of rigs and templates will likely make the FCP X combination with Motion very useful in certain situations, such as organisations wanting to establish a consistent visual identity, or individuals who want dynamic control over Motion creations as they work in Final Cut. But given the shared mechanisms for media asset management and rendering, the level of integration leaves room for improvement.

Apple Compressor 4 review

While Final Cut Pro X has created a lot of buzz since then, has one of its companion apps, compressor 4, remained in the shadows. Compressor 4, unlike FCP X and companion app business, offers users the warm, fuzzy feeling of a familiar interface and operational methodology.

Visually unchanged since 2007, this new version of the compressor is some significant upgrades under the hood. It lacks FCP X dark smokey look, and now you have to buy it separately, keeps this app much of the older supported codecs that FCP X sorely lacks.

One of the biggest benefits of compressor 4 is the addition of http Live encoding, which offers a complete set of files encoded for range of desktop and mobile devices, in a folder and ready to upload to the server.

Encoding files on a variety of bit-rate video stream can be divided into smaller http downloads, each representing a portion of the stream that can be customized by the accepting unit based on bandwidth or other features of the network.

Compressor offers six pre-configured options, broadband at 5Mbps and 2.5 Mbps, Wi-Fi high/low at 1.25 Mbps and 750 Kbps and Mobile high/low at 500 Kbps and 220 Kbps. stream http Live offers the advantage to move freely without being blocked frequently by firewalls or proxy servers in the same way as a typical would be.

Typical video streaming methods fail to work when behind some firewalls or proxy servers on sockets required by current is blocked. Http Live streaming is immune to this problem, because it uses port 80 via HTTP protocol, just like a normal Web page.

Most updates to compressor 4 is buried deeply under the hood, but the most notable of them is the seamless integration with FCP X. This means that a majority of users direct access multi-core or multi-machine compression and transcoding power without having to start the compressor.

As well as FCP X and exercise 5, compressor 4 offers faster 64-bit processing of ProRes codecs and h.264, but maintains the legacy support for older 32-bit codec still in use. This version offers users both power and speed, while quiet residing in the background until needed.

Complex rendering benefits from a 64-bit applications, the more processing can be handled in memory buffer at once. Export directly from within FCP X uses 64-bit processing to handle rendering of complex video and audio, while encoding is handled on 32-bit.

Why has Apple done it? Because only make compressor a 64-bit applications would not resolve the problem with codecs that are optimized for 32-bit or which do not come with Hyper-Threading technology. In fact, multiprocessing and network rendering can save more time than just with compressor on 64-bit. Not to make compressor 64-bit, Apple preserves compatibility with a wide range of current third-party 32-bit QuickTime codecs, which makes the transition to FCP X easier for some users.

For example, a multithreaded ProRes codec full advantage of all this processing. By using all available cores, are affected regardless of whether a machine or over a network rendering, it does not adversely by a 32-bit encoding process.

Apple sees the 32-bit encoding as a basis for many of the professional workflows that are not supported yet in the new version of FCP X, and it allows users the ability to continue migrating between pre-existing formats or file types to those that are more versatile in FCP X.

Most third-party plugins will require an update to work with the new processing engine, however it appears Apple has already begun to take steps to assure that is updated from the current developer will allow the compressor to work seamlessly, including the ability to use hardware-based compression, acceleration, Matrox CompressHD, during which both present and future OS development.

Apple says it markets the compressor as a separate app to completely rather enable its power adaptation than bury it in FCP x's menu. According to the new FCP X proportion available menu, common encoding workflows, and any custom settings created in the compressor 4, now available directly from the timeline.

Compressor 4 enables users to create and customize compression settings and droplets, like previous versions.?This adaptation has the added benefit of allowing users to share settings between computers.

Compression settings created in the compressor 3.x is directly transmitted to the compressor 4 by dragging the old settings to the new version. Just go to/Users/username/Library/Application Support/compressor folder, copy the existing custom settings from the compressor 3.5, and then drag the files to window settings in compressor 4 and all of your previous encoding settings are now immediately available for use in your new apps.

While HD-DVD format is no longer supported as of this release, is one of the other files with changed settings useful. You will need to set up separate encoding pipeline if you plan to use FCP X alongside the previous Final Cut Studio. If you are encoding cluster for compressor 4 and FCP X, make sure you have compressor 4 loaded on each computer in the cluster.

Keep in mind that Apple via Mac App Store, you can purchase an application once and install it on all your of personal computers. You can install the compressor on multiple Macs and set them all as personal encoding nodes with a single purchase of app.

Apple recommends that you stay with Compressor 3.5 cluster if you intend to continue to work with Final Cut Studio, but using compressor 4 If you plan to work with FCP X and exercise 5.
