Insightful as always, Philip.

Oversampling is indeed useful. However, All the camcorder manufacturers have demonstrated how pixel-shift, undersampling and interpolation can make undersampled images appear quite adequate. Elsewise the HVX-200 would look like the SD camcorder it really is.

Great stuff as usual Anthony, however I’ll make one comment on why 12 Megapixels for acquisition (even for less than 2 Mpixel displays): Oversampling at source is a good thing. The quality all down the line is better. This is why an inexpensive HDV camcorder outclasses much more expensive SD camcorders when in SD mode. The HD source is oversampled for SD display.

Oversampling at source is a very good thing.

Your point about how misleading pure statistics are, is pure gold though.
