PSD looking low rez on FCP… why?
I’m suddenly having a problem with my psd images looking low rez when I place them on an FCP, 8bit uncompressed timeline. I build them as 640×480 at 72dpi. Any suggestions on how to make this go away?
Thanks,

Actually the resolution’s not the problem. I’ve also imported some images as 144+ DPi to do moves and still get the same issue. It looks like the lines of resolution are being halved. Horizontal resolution looks ok, but it’s the vertical that looks to be the problem. Here are links to two images that show the problem. https://www.roadrunnerproductions.tv/hirez_jpeg_imported.psd and https://www.roadrunnerproductions.tv/lower_3rd_overlay.psd

No…not DPI. DPI is meaningless in video. PIXEL RESOLUTION. Take the 640×480 image and make it 1280×960….then bring that in. DPI could be 600 it could be 72…you would get the same quality if your dimensions were the same. Bigger dimensions is what you need in FCP.

Are you editing SD or HD uncompressed? If it is SD for broadcast…create your graphics at 720×486. If they are HD 720p create them at 1280×720 and if HD1080 create them at 1920×1080. Photoshop has all the presets when you create a comp.

I wouldn’t simply say meaningless. Not the prefered…perhaps….but we all will address scanned photos to and from clients in DPI at some point.
72 is video DPI. It shows up in photoshop – which is also used for video – as 72 DPI. You do suggest changing the image size as a better method but at what DPI is that new image to be? – 72 DPI …it’s still out there. 144 dpi images mean you scale them double their size and so on.
The image size isn’t always going to be laid out pretty for video aspect ratios so dpi adds to calculating the zoom cabablities of an odd sized image for instance.
To clarify…are you saying that 72dpi images at larger pixels sizes work correctly scaled in FCP where images of alternate dpi’s like 144 do not scale or move correctly?

Also,
what is the screen size you are working in, in the 8bit timeline? Is it DV sized at 720×480? Or maybe 720×486? Your .psd images are 640×480? Double click on your images in the timeline and look under the motion tab. Scale is not at 100% is it? Is it like maybe 112.5?
640×480 into 720×480 (guessing here) gets scaled. I believe that is your issue.

Well, OK…not MEANINGLESS…but DPI doesn’t have the impact that pixel dimensions do. They are more important that DPI. But DPI is good for the initial scan of the image.

DPI is what is used by scanners to generate pixels. The higher the DPI the more pixels scanners will generate, producing larger images. The problem with DPI is that it also produces lots of patterning and very high resolution pixelization creating moir

Are you looking at this in your Canvas / Viewer or on an external monitor? What you have on your website would be normal if you’re looking at this on the computer in an interlaced timeline. This should look normal on an external NTSC or PAL monitor, unless you’re working in progressive

Thanks Donald,
I goofed. If I had said PPI, I might have gotten the answer I was
looking for. The real issue is, I’ve been doing it right for many years and
it’s looked great. Now suddenly, things are looking all wacked up. I was
assuming it would be a problem other folks are experiencing (maybe because
of a program update or OS upgrade, and that maybe someone figured out why.
I shoot and edit both HD and SD, but on this project it’s SD.
