HUGE loss of quality from library to timeline?

I'd just like to chip in and say that i didnt notice it with the SD files from my previous camera, but i've found it quite noticable with the HD files from my HF11 (See attached files).

Its quite off putting - and although probably unrelated, if i make a normal (SD) DVD from my AVCHD files, the quality is noticable degraded (much like the difference between previewing files from the library and timeline).

Hi Russ,

I absolutely concur. If I want to make a DVD I render to Mpeg2 HD (blu-ray profile) to avoid the poor AVCHD rendering then use another application to burn to DVD to avoid the poor downscaling. This is a shame as the disc module in PD is pretty flexible for an editing programme. Luckily I usually just stream the Mpeg2 HD to my media player.
Another option I use if I know the project is just for DVD is to use the bundled camera software to convert to mpeg2 prior to editing then PD is great all the way through.

Im glad to see im not the only one whos noticed it - ill try your suggestion about converting to mpeg2 first.

Shame really, the main reason i bought PD7 was for its abitlity to handle AVCHD content, but i didnt realise the downscaling performance would be so poor.

How was that 2nd photo created? I notice considerable loss in detail around the license plate area. You can almost read it in the first photo and it lacks definition in the 2nd photo. Win8 64-bit Pro Retail

There both snapshots taken from the preview window(click on the third button from the right, select screen snapshot).

Thats the difference in quality that is displayed in the preview window. When you select a clip in the media (library) area and preview it, the quality is great, but when the same clip is on the timeline and you preview it, the quality is fairly poor.
