Photoshop Resolution Settings for HD Video

I recently made an intro tile using Photoshops Default setting of 72dpi. I added text and an image to it (JPEG) The image and text "fall apart" pixelate etc when shown on my HDTV.

What resolution do i need to make the text, images, etc so that it doesnt look bad?

I found this thread, but got lost when they started talking about scanning images.

even for SD I make everything I do in PS 300 dpi.


It also seems that Lucinda Sans works better than Arial. MAybe it doesn't but to my eye, it seems to hold together better.

David, if you have vegas installed just open photoshop

File New
Then in preset you will have a "Film and Video" option. Select this.
Now in "Size" you can select the presets for HD.

I suspect the colors involved with your image could be changed and it would work out better for you.

dpi is for printing, it has nothing to do with video, just go to New/File and set your width in pixels to 1920 and height to 1080 and create your text in it.

David, create your own custom Photoshop presets if you have to and ignore dpi as it's a print term and has no relation to video.
Pixel size is the only thing you need to be concerned about.

The only time I'm interested in dpi is when I'm scanning images and, even then, I look at what the final image size in pixels will be at a specific dpi setting.
My rule of thumb is that 1" of image size at 100 dpi = 100 pixels.
I generally scan at 150 dpi.
Therefore, a standard sized photo (6" x 4") comes out to 900 x 600 pixels.
This is slightly larger than needed for NTSC (720 x 480) so I can do some mild zooming if desired.
At 200 dpi, this same image would be 1200 x 800 pixels, at 300 dpi it would be 1800 x 1200 pixels, etc.

Scanning Basics 101 - All about digital images, the website I mentioned in the thread you referenced, has a few pages dealing with the issue of dpi and video.

Khoi is right. DPI is for printing. You're using red on a black/white background and this combination is very poor. Red for titles can work, but certainly would not be my first choice. Your background changes from black to white and this is also a poor choice IMO.

Your design is the problem, not the image quality.

Ignore dpi, it means nothing in video.

Thanks Jeff!

Its part of that learning curve going from still photography to video! Sometimes I feel like a newborn calf-standing for the first time!

Thanks again

720 x 480 is SD resolution. Try creating a title that matches the frame size of your project. For HDV, I create 1440x1080 with 1.13 pixel scaling within photoshop.

Also, your full range gradient will kill any encoding scheme. Try not to apply gradient in that extreme (from full white to full black). Also, pure red or a block of red is very difficult to encode well in video. Also try to import the PSD file or export in PNG to reduce compression artifacts. JPEG doesn't work well with line art.
