jpeg quality of photos

Post by archivistscott »

version 9 videostud' windows xp home. standard mpeg- 4:3

I have scanned my jpeg still photos at 900-1100 resolution. The movie burned onto a dvd is 15 min long. However is it normal for the photos to appear somwhat blurred. The quality looks better on the ulead program screen. I am watching the dvd on a 19'' magnovox.

Can I do anything to improve the quality? These pictures are not blurred. But some appear more blurred than others when viweing from dvd on this standard tv. Would a better tv be a significant improvement?

I don't think another TV is going to improve things. The problem is created by your images, scanning properties and subsequent modification within VS to fit onto the screen.

I'm afraid, your statement that you scanned your images to 900-1100 resolution doesn't mean a thing. In case you meant to say 900 x 1100 pixels, that's not 4:3 aspect ratio. Resolution is not measured at pixel x pixel, it's measured in dpi. What were the dpi settings when you scanned your images? What were the source images?

I have used digital pic's and scanned images in video projects with very good results. One thing I don't do, is to let a NLE program like VS, MSP, take care of the correct sizing of the image. They are not good at it because they are not meant for image editing. The second problem you created for yourself is the choice of jpeg compression for your images. Scan to tiff or bmp and size to TV screen size, 720 x 576 (PAL) or 720 x 480 (NTSC).

... and if your video is exclusively a slideshow, make sure you use Frame Based as the Field Order setting.

The 900-1000 I am speaking of is the measurement in which I scan into adobe photoshop. Obviously I am a new at this. So then do I rescann the photos as tif or bmp as suggested? Would a hd dvd make a difference?

sorry about crossing the topic area.

In addition to the suggestions by my esteemed friends - apply the anti-flicker filter to still images.

So to sum up
  • Resize in an image editor such as Photoshop / PhotoImpact to a standard TV size.
    NTSC = 720 x 480 : PAL = 768 x 576
  • Use a frame based 'field setting'
  • Apply the anti-flicker filter.

How could that make a difference? By simply changing it to HD does not increase any of its characteristics.

What are the source images, photos? You should scan these to tiff or bmp at the original size and about 300dpi. Then use an image editor like PhotoImpact, PhotoShop or such and crop/resize these to the proper screen size.

Hi

Scan or edit your images to a 4:3 ratio

If you are in Pal area use 768 x 576.

If you are in Ntsc area use 720 x 540.
