iMovie supports audio codec of MP3, WAV, M4A, AIFF, AAC, if you video files are encoded in other audio codec, such as ac3, dts, mp3, you can encounter the problem of no audio in MP4 video playback in iMovie. The problem is caused by the audio codec isse.
The Reason why there is no sound or missing audio in MP4 imported in iMovie, iMovie for iOS iPhone/iPad and the Fix Though, MP4 is a supported video format for iMovie, many users find that MP4 video has no sound or audio after imported in iMovie (iMovie 10, iMovie 10.1.9, iMovie for iOS iPhone/iPad included).
All together I am very happy that I did update to the to the 3GS, now I just have to figure out what I am going to do with the extra 11 gb of space I have on the new Iphone.In the early post, TechiSky introduces the Best Video Format for iMovie, which is MP4, MOV, MPEG-2, AVCHD, DV, HDV, MPEG-4, H.264. I am not willing to take the risk and am willing to wait. I do know that people have tried it and have been successful, but it is unclear what AT&T reaction will be to the unsupported tethering. I am not sure it is worth the $99.00 it would cost. Although the locate me, does look interesting. I haven’t tried MobileMe because I don’t see the need for it at this time. There are a couple of things that I have not tried the first is MobileMe and the second is tethering. A very amusing video on the possibilities is up at Macbreak with Alex Lindsay of Pixel Corp I can guarantee that you are going to see a lot of good quality videos go up on Youtube that are made with the Iphone. mov extension so videos taken this way can easily be edited in Imovie. It did take awhile for Youtube to process it, so I also imported it to Vimeo. This is a picture I took with the Iphone 3GS I also did a short video, to test the video capability, which I downloaded to Youtube.
The one upgrade that I am impress with is the addition of video capability to the Iphone and the upgrade of the camera to 3 mega pixels. It may get better over time as upgrades come in, so I will try it again later. It is not something that I will use very often.
Plus to activate it you have to push the home button, which is not very convenient if you are driving. I couldn’t get the voice dialing to work at all and the music activation was iffy. The Voice control command, while neat in concept, only works sometimes and quickly becomes frustrating. I suspect this application, will become more usefully once applications like the Tom Tom become available that use its capability. You click on the icon and Google maps locates you very quickly and accurately. The compass can be set for true north or magnetic north. The first new application you will notice is the compass. Once you finish syncing and you’ve received the message back from AT&T your phone is ready to use. The phone then starts syncing automatically, that process does take sometimes especially if you are syncing a large library. I wasn’t in any hurry so, I didn’t see a need to do that. I do know that some people had trouble with this part of the process and were popping the Sims card from their old Iphone and placing it in the new one to speed up the process.
I received the confirmation that they had finished the registration about 2 hours later. Once you connect with AT&T, you will get a message telling you that they are processing your request. The connection and process with Apple went without a hitch and was done fairly quickly. If you do use your computer to charge the Iphone, make sure you have Itunes set up and ready to go.
It took about and hour to charge the phone up, which is pretty fast. You can either do that by using the usb cables and connect it to your computer, or you can use the wall charger. The phone is not charged up when you get it, so that is the first thing you need to do. Other then those small differences it looks almost exactly the same. On the original Iphone they were all black. The volume and lock buttons on the side are silver as is the off button on the top. It is completely glossy black, where as the original one had a silver matted back. It is also rounder in the back, most likely to provide room for the video capability and compass. It is slightly heavier then the original Iphone. There are also instructions, legal paper work and finally the apple stickers.
In one of the sleeves is a small tool used to pop out the Sims card. Under that are the earphones, the charger, which is a lot smaller then the previous ones, plus the USB connector. Upon opening the box the Iphone is the first thing you see. The box that the IPhone 3GS comes in is the same as the previous Iphones. The Iphone 3GS came in on Friday, June 19 at about 2:30 pm, which was on time, since they said the package would be delivered by 3:00 pm.
