putting pictures in a slideshow come out blury
Posted by Kyle Fishel on May 18, 2010 at 8:49 pmI’m trying to make a sideshow in sony vegas 9 and every time I put pictures in that are high quality the quality drops so that everything is fuzzy. Does anyone know how to fix this?

May 18, 2010 at 9:37 pmWhat’s the size of the images (in pixels, please)?
What are you viewing them on to say that they’re blurry? -

May 18, 2010 at 9:42 pmThe size differs but mainly it is 1932×2576 in pixels and its blurry in the preview screen as well as when I render it. There are also black bars on the sides of the pictures on some. Not because they are too tall I have tried adjusting it using the event pan/crop and the bars are always there. Thanks for the help.

May 18, 2010 at 10:25 pmJPEG or TIFF? I’ve gone with TIFF format as they usually end up rendering better in video.

May 18, 2010 at 11:02 pmIf the final destination is a DVD, then a TV monitor/TV set is where you should be judging quality and nowhere else.
Unless you’re doing deep zooms on the images, they’re too large in size and can potentially cause problems such as flicker.
You didn’t say where you’re from but SD (standard definition) NTSC is 720 x 480 and PAL is 720 x 576.
The usual recommendation is to not go more than 2X this size (1440 x 9860 // 1440 x 1152) unless you’re doing deep zooms on the images.
I use IrfanView (it’s free) to do a batch resize on all my images before I bring them into Vegas.
To get around the black bars on the images (it’s a square vs. rectangular pixel issue with stills being square), click the first one, open the Pan/Crop window, right-click and select Match Output Aspect.
The image will now stretch to fill the frame (i.e. no black borders).
Exit Pan/Crop and Copy the first image.
Click image #2, go to the last image and Shift+Click it.
This selects all of them.
Right-click on any image and select Paste Event Attributes.
If you’ve followed these steps, all your images will now be stretched to fill the frame.
Be advised that Paste Event Attributes will paste any and all corrections (such as colour correction) that you made to the first image so this is something that I highly recommend doing as a first step.
BTW, I never recommend TIFF as that particular format makes a “call” to QuickTime for each and every frame of the video.
JPEGs are OK and PNGs or TGAs are even better. -

May 18, 2010 at 11:04 pmThe black bars simply mean that the photos are not properly cropped to fit your selected video output. The vertical dimension does not seem excessive, so it could be that your source is not as good as you think it is. The other possibility is an error in the project settings.

May 18, 2010 at 11:10 pmI continue to scratch my head about why QT is called to handle tifs. Surely Sony knows that tifs are an Adobe format? Are they simply not interested enough to read and process the image themselves? Apple and Adobe are not on the best of terms these days. BTW, tif is my preferred format unless I am going to Vegas. Then I must convert to PNG.

May 18, 2010 at 11:17 pmThe photos are cropped to fit that’s what I am telling you. I know about if the photo is too tall or too wide it will make black bars like you see on dvds. I am saying some have them and they wont go away no matter the amount I zoom into them

May 19, 2010 at 3:38 amSince QuickTime is opening tif files, I would not count on superior quality. I prefer PNGs which, like tifs, are a lossless compression format. Vegas likes PNGs, JPGs, or Targa.

May 19, 2010 at 4:02 amAlright thank you I followed your steps and it fixed the bars on the sides but added some on the bottoms. I’m just not going through manually and selecting 4:3 in the pan/crop settings to the ones with the bars on the bottom now.
