It's heavy way to convert avi . We must store 2 files, we loose time,

if apple want to win some customer , they must implement :


1- avi , mkv : support

2- sd or micro sd card support

3- hdmi port

4- micro usb support

5- mouse enabled.


they ll strong against the world and all apple's user ll be happy with this functionnality.

Android and Surface has already this , it's not the future but the present.

But why apple do not accept the avi and mkv files ?

Generally speaking, QT does support/accept the AVI file container. It's the data in the file container that may be problemating. Only recent versions of QT apps (e.g., iMovie, QT X, and iTunes) have been updata to either not accept AVI files at all or those containing unexpected combinations audio and video data. As to MKV, it would be subject to the same codec component restictions. However, I agree it would be nice if the file type was recognized/supported even if specific data compression formats are not natively supported by the basic OS codec component configuration. Unfortunately, what ost people seem to forget is that iTunes has, more or less, become a management and streaming vehicle for mobile devices like the iPod, iPhone, iPad, and TV all of which natively support only a very few specific dodes. If you wish to play your AVI and/or MKV files, then use the QT 7 based apps which, at least for the moment, continue to enjoy relatively open codec support for a dwindling numer of legacy and third-party ccomponents.

I don't find it troublesome or time consuming to convert from one or more movies to an entire season of TV shows overnight while sleeping when my computer would otherwise be be idle. As to the storing of two files, I would never keep a secondary copy of content in an AVI container and only keep MKV version if they are my only source for content and in a higher resolution than the converted files I create for iTunes management of files for mobile device syncing and/or private streaming when home or on the road.

I personally think Apple is more interested in the iTunes Store customers that any "do it yourself" customer base here.



1- avi , mkv : support

QT based apps programmed to "accept" the AVI files continue to support this file container as long as the compressed data is supported and in a combination that the QT app is programmed to expect/allowed to play. As to MKV, as previous noted, you can request an app enhancement to recognize/accept this file container natively in the app's associated "Product Feedback" form.



2- sd or micro sd card support

Invest the $6 to $40 required for a card reader that supports any or all formats to include CompactFlash Type I, CompactFlash Type II, MicroDrive, RS-MMC, MMC, SD, MiniSD, MicroSD, SDHC, MemoryStick, MemoryStick Pro, SM, xDPC, etc.



3- hdmi port

Some Macs (e.g., MacMinis) have had HDMI v1.0 through v1.4 supported ports since 2010. I've had a MiniDisplay to HDMI adapter for my MacBook Pro even longer.



4- micro usb support

USB support is built into Mac OS X software. Virtually all of the micro-USB and Mini-USB devices I've purchased came with a USB to Mini/Micro-USB cable. If yours did not, then invest the $0.95 to $30 the specific cable you need or ask a friend to loan or give you a spare cable.



5- mouse enabled.

Mouse enabled what?



itunes accept mp3 support , why they don't accept avi

MP3 is both a file container and a compression format while AVI is merely a file container with no dedicated compression format associated with it. Further, MPEG-1 layered audio content has been playback supported for as long as QT has been suporting "muxed" MPEG-1 audio and video while some legacy AVI compression formats have never been trancoded for use on the Mac, never made it past OS 9, were dropped with the demise of the PowerPC CPU, or dropped with the introduction of Lion/Mountain Lion. In short, Apple claims it is modernizing its media players not trying to make them compatible with legacy file types and lagacy codec components which are no longer available for the Mac or no longer supported by their originators. (E.g., Microsoft introduced the AVI container in November of 1992 as part of its "Video for Windows Technology" and dropped active support with the introduction of WMV media more than a decade ago due to numberous file type limitations not anticipated in the original AVI specification.)

When i say Hdmi port it's for Ipad or iphone, not macbook or mac.

I use AirPlay and Mirroring for simultaneous HDMI playback connectivity via TV devices to my main AV Reciver-HDTV system and direct connection to 3 or 4 other HDTVs plus the same AV Receiver for FuryHD HDMI recording if needed/required. Current IOS on recent iPod Touch, iPhone, and iPad models all have this wireless capability.

And for the rest, it's too long to explain you, i see you don't understand, and you must to play with android to understand the complete hardware.

You are correct in that I do not understand what specific functionality you desire that is not already available to you via the connectivity mentioned above. And, since it would, in your opinion, take too long to explain, I guess I never will understand. However, as my current work flows provide all the cennectivity I need for direct wired, in-home wireless, and out-of-home internet access to 32 TBs of content stored on my main computer external RAIDs, I do not feel any great need to buy or use an android-based device. If that is what you need, then fine... By all means use such devices yourself. My needs are obviously different than yours just as my idea of proper work flow and what constitutes modern tecnology/techniques differs from yours. As to what's "important for the future to win the market," I am willing to sit back and wait to see which way the winds of change are blowing.

Is this how apple users have been living all these years?

No, AVI is a legacy file container which remains compatible with QT 7 "legacy" player apps assuming the required codecs are both available for the Mac and installed on the users operating system. Basically, Apple is currently embarked on a program of modernization of QT based structures and apps that employ these structures. E.g., the QT embedded structure is now basically a hybrid to support the various apps like QT 7 and GarageBand ("classic" QT) and QT X, iMovie, and iTunes (which have more or less crossed over to "the dark side" of QT).


On the other hand, why do you wish to use a "legacy" file container initially developed and introduced by Microsoft in November of 1992 and for which Microsoft dropped official support eleven years ago as part of its own program for multimedia modernization to overcome a mutitude of AVI file container limitations? For example (See Wikipedia "AVI" article here):


  • AVI does not provide a standardized way to encode aspect ratio information, with the result that players cannot select the right one automatically (though it may be possible to do so manually).
  • There are several competing approaches to including a time code in AVI files, which affects usability of the format in film and television post-production, although it is widely used. For WAV audio files, Broadcast Wave extensions were designed to standardize post-production metadata, but an equivalent for AVI files has not emerged.
  • AVI is not intended to contain variable frame rate material. Workarounds for this limitation increase overhead dramatically.
  • AVI was not intended to contain video using any compression technique which requires access to future video frame data beyond the current frame. Approaches exist to support modern video compression techniques (such as MPEG-4) which rely on this function, although this is beyond the intent of the original specification and may cause problems with playback software which does not anticipate this use.
  • AVI cannot contain some specific types of variable bit rate (VBR) data reliably (such as MP3 audio at sample rates below 32 kHz).
  • Overhead for AVI files at the resolutions and frame rates normally used to encode standard definition feature films is about 5 MB per hour of video, the significance of which varies with the application.


Basically, the file container was designed for use with "legacy" compression formats being abandoned by both Apple and Microsoft and which are becoming harder and harder to support on a continuing basis and still retain compatibility with the more modern compression formats available today. A better question might be "Why doesn't QT natively support a more modern file format type like MKV?" which was developed as an open standard for the universal storage of an unlimited number of video, audio, picture or subtitle tracks in a single file. The use of AVI only retains its current popularity because most users do not know of its limitations and those that do are, for the most part, simply too lazy to make the effort to modernize their files.
