    Just finished a project that was completely Jpg images.
    The image file sizes were 960 x 720, this size did not fill the screen there was a gutter on both sides.
    Do imported images need to be 720 x 486?

    I resized the each image to 720 x 486 to fill the screen…About 300.
    My other question is, is there another way to achieve a full screen image of the slides other than changing each individual slide?

    Thanks Gary

    If you have Photoshop you can use the Batch function and do them in a hurry!

    Be sure the images are 72dpi. Also if the images were not made for video’s rectangular pixels they will still be distorted. A circle looks tall and thin. There is a formula for correcting this in photoshop. Let me know if you need it.

    Using Photoshop create or bring your image into a canvas 720×576 @ 72dpi.
    When working with higher res images I resize it at the higher res and drag it into the 720×576 canvas using trail and error until it looks right. You may need to create a border to keep the image in the safe area.
    Once you are satisfied flatten the image and resize to 720×486, also change the canvas size to 720×486 (It will look distorted in Photoshop). Save as a jpeg and load it in trinity.

    If you are using After Effects there is a D1 option built in.

    You should not bring it into the trinity in jpeg format. Jpeg is a lossy compression. Save it as a tif file and then open in the trinity app of choice.

    D1/DV NTSC Uses a 0.9 pixel aspect ratio. Use this setting if your video has a 720 x 480 or 720 x 486 frame size, and your desired result is a 4:3 frame aspect ratio.

    D1/DV PAL Uses a 1.0666 pixel aspect ratio. Use this setting if your video has a 720 x 576 frame size, and your desired result is a 4:3 frame aspect ratio.

    Depending on what card you use. It could be 534 or 540 for ntsc
