Re: Does HD production increase quality on SD broadcasting?

The simple/broad answer is "no". The main reason why HD equipment doesn't improve the SD quality is because HD is square pixels and SD is rectangular pixels. The scaling effects going from HD to SD are generally worse than if the source was SD to begin with. This is not true, however, of 4K/5K/6K downscaling to HD. Both of these are square pixels, so you can get really good scaling between them.

Now there's always an argument for better equipment. For example, there's a good chance a great modern camera like an Alexa would capture a better quality signal overall, that even scaled to SD would better your existing equipment. Things like dynamic range, camera color gamut handling, lenses, that type of thing can have a good effect on the overall output. But scaling it to SD will always take a big chunk out of the quality.
