Photoshop super shifts
I’ve noticed over the past few weeks that I’m getting a vertical shift in photoshop super graphics when there is a transition or shot change in the main video on the track below it. They are multiple layers psd files that are not flatened wen I import them into finalcut. I noticed on one (there was an orange mark above the transition) that if I didn’t option render it, it played fine. If I did render it the shift was there. The problem comes when I have multiple tracks with transitions I have to render and then am stuck with the shift. I am using finalcut 4.5 and photoshop 8.0
Any suggestions are much appreciated.

Are you moving and positioning your graphics in the Canvas? You need to make sure your graphics land on a even Y/vertical integer under the Motion tab.
From one of my posts in Feb. 2005
https://tinyurl.com/crqkrThe trick to bring in Photoshop layers in registration is as follows:
1. In Photoshop create a new layer at the top of your layers and name it Ref or Reference and make sure it is selected.
2. Create a one pixel selection in the upper left hand corner. Hint-zoom all the way in and try and make the small Marquee Tool selection.
3. Go to the Navigator and move your view window all the way to the lower right and hold the Shift key while making the Marquee Tool in the lower right hand corner-you are adding to your first selection that is still in the upper left hand corner.
4. Fill the selection, the two points in the upper left and lower right hand with Black. Hint-Opt+Delete to fill with the foreground color or Cmd+Delete to fill with the background color.
5. Type 0, 1 to make the layer 99% transperant or 01% opaque.
6. In the layer menu hold the Opt key down and select Merge Down from the upper right hand pull down menu (the little arrowhead pointing to right you see at the very top of the Layers Window) over your layer of rasterize text. Then for each layer of rasterized text place your Ref layer just above it and repeat holding the Opt key down and selecting Merge Down from the upper right hand pull down menu making sure you Ref layer is the one selected. What this does is make each layer of rasterized text have the same canvas size and registering the position of your text or any layer element in the Photoshop document. Holding the Opt key while selecting Merge Down prevents the Ref frame from destroying itself when Merging Down. It in essences merges a copy of itself down.
7. As a rule of thumb I then place the Ref layer at the top of the document, select it and type 100 to make my two pixel dots in the upper left hand corner and lower right hand corner visible so I can see them if I zoom in to make sure they are there.
If you work in SD ITU-601 you could alway have a template .PSD file with a canvas size of 720 x 540 with your Ref or Reference frame already in there along with a SafeTitle layer. If you work in DV you want a canvas size of 720 x 534. If you use these numbers, FCP will automatically recognize number and resize to 720 x 486 or 720 x 480 respectively. If you use a larger canvas size make sure it is in the TV 4 x 3 square pixel aspect ratio. Let’s say your .PSD canvas is 1440 x 1080 and FCP doesn’t recognize that aspect ratio, go to Motion>Distort>Aspect Ratio and type in -12.5 to achieve the video pixel aspect ratio of .9. Don’t ask me why the Aspect Ratio of -12.5 works in FCP, but I do know that is the number FCP automatically calculates when you import a 720 x 540 .PSD canvas into FCP.
As a disclaimer Apple’s knowledge base indicates some slightly different Photoshop graphic starting resolution numbers:

Thanks for the suggestion. I had our artist try it with no success on the shift issue. I don’t think I described the problem correctly. I get graphic files from teo artists at the station via network deartmental connection. One artist gives me files through our sans disk fiber connection. Those files I never seem to have a problem with. The other artist leaves files via a drop box on the network connection. His files are the ones that seem to be giving me problems. They are layered images that I turn different layers on and off depending on the spot and sponsor. The other file was a logo with multiple layers. The problem occurs on the rendered transition (dissolve) adding this graphic or disolving from one graphic to this one over a video track. I have also seen the problem with the graphic shifting with a transition in the video track beneath it. We have tried various changes to the graphic in photoshop including the one you suggested but can’t seem to solve the issue. We don’t know if it was an issue with the way he creates the graphic or something in the importing process. They are .psd files.
On the first graphic I had a problem when I tried grabbing the layers I wanted out of the master graphic and then pasting them on the timeline separately for each sponsor. I solved that by just copying the master file and then within it turning the appropriate layers on or off. I still noticed a slight shift in the graphic on transitions in the video layer beneath the graphic. There were no changes within the graphic clip on the higher layer.
Thanks for any more suggestions ahead of time.
