Adobe Premiere Pro CS 5.5 brings better handling of medium framerate videos recorded as PsF

You may have noticed that even many late model AVCHD cameras shoot medium framerate progressive video (i.e. 1080/25p and 1080/29.97p) as PsF (Progressive Segmented Frame), meaning that they (unfortunately) record 25p-over-50i and/or 29.97p-over-59.94i. This regrettably occurs with both consumer and even some of the latest professional AVCHD cameras with the mentioned progressive framerates. Fortunately, this practice doesn’t damage the internal AVCHD video recording quality to any perceptible degree since the encoder knows that it’s progressive, but unfortunately it makes the video more susceptible to being mistreated later on, either by a video editing program which mistakenly thinks that it is interlaced and consequently de-interlaces it when importing it into a progressive timeline, or by an HDTV set that does the same thing. Unnecessary de-interlacing is a bad thing and should be avoided when bringing progressive footage into a progressive timeline… or into a progressive display device, like an LCD, Plasma, or projector. One of the best ways to prevent unnecessary de-interlacing is by recording the progressive signal natively (not as PsF), but that’s not the case with many cameras when shooting 1080/25p and 1080/29.97p. This article will clarify the issue further, explain how we overrode it manually with Premiere Pro CS 5 and Media Encoder 5, and how the 5.5 upgrade resolves it automatically! Read the rest here…
