Hi, I am trying to acheive a good quality slide show, I'm not convinced the aperture slide show - toast- to dvd is that good, the quality is not the same as the folder of files that I'm viewing in aperture, once on dvd the quality suffers.

 

So I am usuing toast, for mac and pc format.

 

When putting images straight to a cd i have good quality.

 

Any thoughts please?

    More info regarding the settings you're using throughout are needed to even begin to think about this.

     

    However one of the biggest causes of poor DVD quality is trying to put HD video on an SD disk.

    ok, i make a slide show in aperture, then add the files to toast 10 on setting mac & pc, and i have my sldie show ready, thats all I'm doing.

    Without knowing the settings you are using there is no way to attempt to fix the problem. 

     

    As I wrote if you are trying to put HD video on an SD disk then that would be the first thing I would change.

     

    Again sorry but with the information you've supplied there isn't much more I can do.

     

     

    regards

    In addition to the above, are your Previews set to a high quality?  This _is_ basic, but is often overlooked.  From the User Manual:

     

    About Displaying Sharp Images in Slideshows

    To display slideshows at the best quality, you should set Aperture to create high-resolution previews. In addition to setting previews to their highest resolution, you should also use full-size previews to prevent upscaling with large displays. If previews are not available, images in the slideshow may not be as sharp as they would be otherwise. For more information about creating high-resolution previews, see Working with Preview Images.

    A good point, Kirby!

    I have often wondered if this also applies for slideshows rendered and exported as video or not. It is certainly true when viewing the slideshow from Aperture or as a Scrennsaver. But I have been hoping that Aperture would use the master files to render a slideshow on export, not the previews. Rendering the slideshow takes a very long time. Using the masters when rendering and exporting would be consistent with the export strategy for images.

     

    The manual is very vague  ...

    Yes.  Your point is important.  The part I cited is from the section on viewing slideshows in Aperture.  Exporting involves selecting an export size/format -- and it is not clear whether the Images used are the Previews or are rendered from the Master+Version prior to being rendered as a movie.

     

    I don't do video and don't even know how to check which Apple does, though it must be fairly straightforward to create a slideshow using Images with very low quality Previews, export it, and see what you get.

    Good suggestion, I'll try it over night.

    Or no previews. Delete the previews for two or three images and make a slide show from them, what happens?

    O.k., here is a test:

    I rendered a slideshow (classic theme) from jpeg without previews.

    Export format HD 1080p, codec: H.264, pixels: 1728x1080, the highest resolution Aperture offers.

     

    The video looks o.k., but not as crisp as the original images.

     

    I really cannot tell, if the images actually have the full resolution.

     

    I put three testimages on my MobileMe Gallery: http://gallery.me.com/dreschler#101100

     

    1. The original image:

    2. A section of the original image (above) and 3. a section of the same image in the rendered slideshow:

    This images will be gone in June - Bye Bye Mobile Me.

     

    Cheers

    Léonie

     

    P.S. The still frame fom the rendered slideshow was extracted with the video tool in Aperture. There are no options to set the quality of the resultinng still. But the quality is very similar to the actual video.

    Extracting a still frame in iMovie does not longer work how it used to be - the stills seem to be videos now.

    Dave,

    You seem to have gone missing from this discussion......

    From your limited discussion it sounds like you have created a data dvd from Toast.   May not be the best way to approach this. 

    I think you want your DVD to be a video.  But as the other respondants have pointed out DVD is standard definition.  Not HD or Bluray.  You dont say how you are viewing the final product.

     

    With Toast you can create a Bluray movie, if you have a BluRay burner and BluRay player.

    If you do not have a BluRay burner but do have a BluRay player or PS3 you can create a 30 min or so movie in full BluRay on a regualr DVD.  But that DVD needs to be palyed with a BluRay player, not a regualr DVD palyer or Apple Computer.

     

    If you want to go the BluRay route I can help with that, but first as the other responses have stated check your preview settings.

    " I really cannot tell, if the images actually have the full resolution."

     

    You could open the movie with Quicktime.  Then Window> Show Movie Inspector

    Quicktime.  Then Window> Show Movie Inspector

    That confirms that the rendered movie indeed has the pixel size 1728x1080 that I specified on export, but I cannot really judge the quality the compressin on my screen.
