The colors still look great and are sharp enough for clean chroma keying and graphics compositing. All the professional DVCRs such as DVC PRO 50, Digital-S, and Digital Betacam use this sampling. Thus the luminance remains as sharp as the better DVCRs, just the color is degraded. Still, the loss is hard to see. They're not there.
Vertical resolution is halved, but c'est la vie.
Audio edits may have brief silences or clicks as the sound catches up to the picture. Their audio edits are perfect and accurate. Tape consumption Recording formats that spread their magnetism over a larger area are more robust. They stand up to the rigors of editing and are less sensitive to tape dropouts. Manufacturers, in effort to pack the most data into the tiniest space, have reduced the detectable magnetism to just whisker above nonexistent.
