| I have 26 short video clips, all avi format, all at the beginning of my slideshow, followed by still photos. When I choose burn to disk/test, go through that whole process, and then try to preview my show, none of the video clips play. I can head the audio for each cllip, but no video displays. I read something in the forums re some avi formats not being compatible with DVD PixPlay. Evidently my problem?? What's the next step? Thanks a bunch! |

AVI is a container format. That means that no software can claim to support all AVI formats. DVD PixPlay supports the common ones, others require the installation of a codec, and some really esoteric ones are best converted to an always compatible format such as MPEG
It sounds like you require an MJPEG codec.
The codec is not required to burn the slideshow to disk. It is only used when previewing.
You can get the codec free by downloading the K-Lite Mega Codec Pack:

or at:
http://www.free-codecs.com/Motion_JPEG_Codec_download.htm
NOTE: DVD PIXPLAY DOES NOT SUPPORT QUICKTIME MOV FILES--MOST NIKON CAMERAS USE THIS FORMAT
Thanks to Wilber Johnston who suggested this link to convert QUICKTIME files:

I am somewhat confused by what I find at those links -- many types of downloads. What do we really need?
I installed someting called AVS Video Converter 6 and converted an AVI file to a MPG file but it played horribly on my pretty fast laptop (not in DVD PixPlay but Windows Media Player).

You can add any MPEG, most AVI and generally WMV files too.
MPEG-1 and MPEG-2 are natively supported for (PixPlay can output to MPEG-4 but it can't be used within your slideshow).
AVI is a container format, meaning that it a blanket format for many sub-formats. PixPlay supports the standard ones but for others you need to install a driver. Generally the one that trips most people up is MJPEG as this is commonly used on digital cameras (and Windows does not include a driver for it). If you encounter problems with AVI formats you should install a codec pack.
MOV is not supported at all. You need to convert it to a compatible format (with MPEG-2 being the preferred option).

Jim,
You posted same about a year ago in this thread, which I had already read.
I thought a codec was supposed to make the avi play under DVD Pixplay. Why does the mpg file that I converted from an avi play so badly under WMV?

I don't believe you want a "tech" answer but here is a reason.
Both formats store the information as luminance (Y) and chroma (Cb and Cr) rather than red, green and blue. Each value is an 8-bit number that can range from 0 to 255. MPEG2 (and other formats like DV) require that the Y, Cb and Cr values are clamped between ~16 and ~235 (the range is slightly different for the Y and Cb/Cr values). For MJPEG, that restriction doesn't apply - each frame is nothing more than a JPEG image.
This means that the MJPEG image has a wider range of values to use. A wider range means greater contrast and whiter whites/black blacks. Hence, the image looks much better than the constrained MPEG2 one.
If you have a program like Paint Shop Pro, you can grab an image from each video and look at the histogram of values.
MPEG2 throws away of lot of color information - for every 4 pixels of black and white, you only get 1 pixel of color (a crude approximation).
MJPEG can store the image without throwing away any color information, so the image can look more vibrant.
In short, you are seeing the limits of various codecs.

Hi Bernie
What happens if you install one of the codec packs that Jim suggested (such as K-Lite) and then try to burn the original AVI files to disk?
(Actually you can just click the "Test" button first to see if it works).
