I agree that the quality is indistinguishable from the original AVCHD clips if a project is burned directly to a hybrid AVCHD disc (i.e. a regular DVD disc with AVCHD on it). However, I have found that rendering the original AVCHD clips to an AVCHD file
, with smart-rendering off
, as they suggest, results in a file that plays at a significantly lower bitrate than the original clips, and the drop in quality is quite noticeable. I don't even have to look close to see the degradation. My Sony AVCHD clips are 15-17 Mbps. A VS rendered AVCHD file plays at 9-12 Mbps, even though I specify 18,000 bps and 100% quality in the settings for Share/Create Video File/AVCHD.
In a thread I started earlier this year, I believe there was agreement about this.
Since your interpretation of the Corel's work-around suggestion is they are suggesting rendering the original clips to an AVCHD file, I will try that. But I suspect it will result in noticeably lower video quality in the rendered file. When that file is then put into a project time line, edited, and burned directly to an AVCHD disc, there would be no further degradation, but the disc would reflect the lower bitrate and video quality of the rendered file.
