It’s generally accepted that Macs are great computers for graphic design and audio-visual work – so why is it so hard to play Windows Media content on a Mac? I know that QuickTime is the centre of Apple’s audio-visual experience – so why should Apple support competing formats – but perhaps I should really ask why the various software companies have seen fit to introduce such a myriad of audio and video codecs? I’m a techie and I can only just keep up – think about the poor consumer who just wants to share some family videos with the grandparents!
The trouble is that Microsoft, as the developer of the most widely installed operating system on the planet (with a correspondingly huge number of multimedia file formats as described in Microsoft knowledge base article 316922), has seen fit to dump development of Windows Media products for other platforms. Quoting part of the Wikipedia article on Windows Media Player:
Version 9 was the final version of Windows Media Player to be released for Mac OS X before development was cancelled by Microsoft. WMP for Mac OS X received widespread criticism from Mac users due to poor performance and features. Developed by the Windows Media team at Microsoft instead of the Macintosh Business Unit and released in 2003, on release the application lacked many basic features that were found in other media players such as Apple’s iTunes and QuickTime Player. It also lacked support for many media formats that version 9 of the Windows counterpart supported on release 10 months earlier.
The Mac version supported only Windows Media encoded media (up to version 9) enclosed in the ASF format, lacking support for all other formats such as MP4, MPEG, and Microsoft’s own AVI format. On the user interface front, it did not prevent screensavers from running during playback, it did not support file drag-and-drop, nor did it support playlists. While Windows Media Player 9 had added support for some files that use the WMV9 codec (also known as the WMV3 codec), in other aspects it was seen as having degraded in features from previous versions.
On January 12, 2006 Microsoft announced it had ceased development of Windows Media Player for Mac. Microsoft now distributes a third-party plugin called WMV Player (produced and maintained by Flip4Mac) which allows some forms of Windows Media to be played within Apple’s QuickTime player and other QuickTime-aware applications. Mac users can also use the free software media player VLC, which is also able to play WMV-3 / WMV-9 / VC-1 Windows Media files.
It seems that the Flip4Mac WMV Player, which should provide the missing Windows Media support for Mac users (as endorsed by Microsoft) does not support all Windows Media codecs, namely it refuses to play content encoded with the Windows Media Video 9 Image v2 (WVP2) codec.
I can understand Microsoft’s position – after all they want to preserve their market share – so why doesn’t Apple make it easier for switchers with legacy video content? As the iLife applications are such a selling point for Apple, why not make it easier to convert from the Windows equivalents?
My problem is that, for the last few years, I’ve been creating home video content using Windows Movie Maker and Photo Story. They may not be the best video applications in the world but they are fine for movies of holidays and the kids and are included with Windows XP (well, Movie Maker is – Photo Story is a free add on). Nowadays, I have a Mac but I still want to play my old content.Â The resulting WMV content from Movie Maker hasn’t caused too many problems as it uses the Windows Media Audio 9.1 and Windows Media Video 9 (WMV3) codecs and simply needs appropriate QuickTime components to be installed. Unfortunately the Photo Story output refuses to play the (WVP2) video track in either QuickTime (WMV Player) or Windows Media Player for Mac OS X and as far as I can tell there are no suitable codecs available.
In desperation, I went back to PhotoStory and tried to export in another format but there is no such option (it supports various screen sizes and frame rates but they all seem to be using the same codec).
One macKB thread suggests using Dr Div X to convert the file but the latest version of Dr DivX failed (on both Windows and Mac); similarly the DivX Converter didn’t work for me.
Eventually, I found a utility that could convert the file for me (Advanced X Video Converter) – it’s done a good job although whilst the quality is acceptable for my home movies there are some visible compression artifacts (I used the H264 video and 24bit audio codecs to convert to a .MOV file). In fairness, the compression artifacts may also be visible in the original WMV file and anyway they are hardly surprisingly as the video was created from compressed JPEG and MP3 files, which have then been compressed to WMV and once more to MOV so the quality is certain to have suffered along the way. What’s possibly of greater concern is the resulting increase in file size – up from 19.5MB to 431.4MB.
I’m glad I got there in the end – for a while it seemed that I would have to keep a Windows virtual machine just to play old home movies – and there I was, naively believing that converting to digital capture and storage would save me from issues with legacy formats.
