Poor Image Quality...Anyone?

I have seen the earlier posts, but no one replies, is this not possible? I can take high quality images and use splicer to create the simple fading images and audio example and they always come out in bad quality. I was able to change the resize mode to preserve aspect ratio but that only clears them up a little bit. I am using the WindowsMediaProfiles.HighQualityVideo but no matter what I do, they still lose quality dramatically. Is this just a drawback to Splicer? If anyone has been able to successfully preserve photo quality, please let me know how.

I am in the same boat. I used Splicer to create a video with 1024x768 size images. The result is terrible image quality in the video.

I've tried using a different .prx file and a hex editor to make changes to HighQualityVideo.prx, but the result is always a failed render.

If someone has implemented one of the Windows Movie Maker HD files ( such as WMV-HD-960x720.prx or PublishToFile1080p.prx ), I would love for you to share your compiled Splicer.dll. I think the hard coded 320x240 size is rather unfortunate, and I'm not able to work around the limitations at this time.

Try this to make custom .prx files. You then have to download the splicer source and add-in the .prx to the source; re-compile the .dll and re-include in your project.

Short version:

By the end of the day yesterday, I switched to ffmpeg.exe and moved on to the next step of my project.

Long version:

I had downloaded the latest splicer source and tried compiling a new splicer.dll for a few hours yesterday like you suggest. I tried changing values like the width and height in HighQualityVideo.prx using a hex editor. I tried using WMV-HD-960x720.prx, a file that comes with Windows Movie Maker. I even tried to combine the files. These attempts always resulted in a failed render as I mentioned above.

Interestingly, WMV-HD-960x720.prx seems to have been created with the tool you are suggesting. Inside the file I found:

I know that this is an old thread, but I have a similar problem... The video quality is poor but additionally I don't know how to maintain aspect ratio of images.

How can I do it?

   Have you found an answer to your question?

   I'm having the same problems and I would like some help as well...

I finally desisted on using Splicer. Instead of that, I simulated to play the video by putting the image for X seconds and advancing the time bar.

I used the following search in google (for example):
wmv 720x480 filetype:prx

I was able to find many prx types this way. I copied to a text file, and then loaded the text real time and it worked fine,high quality video

Thanks pselvey!

Just download any desired prx file, replace the file "splicer-source-\splicer-source-\Splicer\WindowsMedia\HighQualityVideo.prx" in the source code, rebuild the solution and get the new created Splicer.dll to your own project :-)
