What is this expansion and contraction?
Ken Burns meets Edwin Hubble.
Why does my Encore-burned dvd expand and contract the viewing rectangle on the tv monitor, meanwhile freezing clips which are zooming in the original?
I am burning DVDs in Encore.
I am a novice with Encore so please forgive me if I use the wrong lingo.
The only prep I am doing is setting stop as an end action.
Everything is fine except the Encore-burned dvd replaces my Ken Burns slow zoom-outs with a two-second screen expansion of a half- inch in every direction of its own, which looks to the viewer like a two second zoom-in since the playback screen is expanding.
(What I am calling a “Ken Burns slow zoom-out” is a key-framed scaling change, eq from 107 to 100 over five seconds. Eg, as I “zoom-out,” the title letters get smaller as the clip plays.)
In other words, when I play the source H264 (burned from Premiere CS5), my dissolve performs just as edited, cross-dissolving into a nice Ken Burns zoom-out.
But on the Encore-burned DVD the first two seconds of the clip don’t show any zoom-out, but are replaced by a screen expansion, which to the casual observer looks like a zoom-in (eg, the title gets bigger) until you watch closely and realize that the entire viewed rectangle is expanding by a half inch in all four directions (call me Hubble for short!).
By “screen expansion” I mean that the viewing rectangle (surrounded by black on my tv screen since the video doesn’t fill the entire screen) actually stretches a half- inch in each direction and then contracts the same amount at the end of a clip. It does this regardless of whether the source clip that I used to burn the H264 is an mp4 or a tiff, which seems obvious because how could Encore know or care what created the source H264?
It is as though a little Encore Man is looking at the content of the clips and saying “Hey, here comes a dissolve! better expand the movie screen…Oops, we are about to dissolve to another clip, better contract the movie screen…” But this is impossible. How could Encore know if two of my clips are separated by a cross dissolve or a hard cut?
Of course, this two second expansion (after which the viewing rectangle is an inch wider) looks like a zoom-in. which basically destroys the effect of the zoom-out. In fact, on playback it appears like a zoom-in which reverses itself after two seconds and becomes a zoom-out. Did Ken Burns have this problem???
During that two seconds of screen expansion I can’t tell if the zoom-out is actually occurring and just not detectable because of the screen expansion, or if Encore decided to just create a freeze frame for the two second screen expansion.
Can anybody enlighten me?
