What’s really bizarre is that I always found video to be actually quite good. Especially when it’s restored. Look at a Doctor Who between 1986 and 1989 - all done on video (they used to use film for external shots until 1985’s “Revelation of the Daleks”).,(reply>), Well, as late as 2008. DigiBeta (a physical tape with uncompressed digital SD video) apparently.<br><br>The Specials set has proper interlaced footage for The Next Doctor and progressive ('film') for Planet of the Dead onward, so evidently they were shot interlaced until the HD switch in 2009; There were still interlaced elements popping up (the scrolling credits, most obviously) until the end of 2013, because technically BBC One HD is 1080i rather than 1080p.,(reply>), mrchips2301 You’re telling me they were using studio tape as late as 2009?,(reply>), The Eccleston &amp; Tennant episodes were actually shot this way, but filtered to look more like film in post-production. The deleted scenes still have the 'soap opera' effect (on the PAL DVDs at least).
