To HD or Not HD : The Quandry Over Podcast Quality

Friday, June 24th, 2011

I have noticed a shift in the number of podcasts I subscribe to that end up on my iPod. Many shows that I have been subscribed to for several years, which adds up to numerous episodes, are no longer making onto my 80GB iPod 5G.

Playing many new video podcasts requires an additional transcode in iTunes

My old iPod supports resolutions of up to 640×480 which translates to a widescreen 640×360. Of course many video podcasts are recorded widescreen these days and 960×540 is a popular size to publish at. It is 50% of 1920x1080HD resolution and offers a good balance of bandwidth and quality. It is also compatible with AppleTV playback. It is not compatible with the older iPods unfortunately.

According to Apple’s tech note iTunes can play a variety of .mp4, .m4v, and .mov video formats encoded using either the MPEG-4 or H.264 codecs, but only provides specs for iPod Touch, iPhone 4, iPhone 3G/3GS, iPad and Apple TV. It seems the trusty old iPod Classic has been dropped from the developer support reference.
