Hi,
I would like to know what kind of settings you are using for your export.
For example, the first image uses the default setting which will export your movie into an AVI with microsoft video 1 compression. I tried that setting and it gave me really poor resolution with gradient background as well.. If you need to use a AVI, I would click on the configure button and choose the uncompressed version. (image2) that will give you a really high quality movie but it will be quite heavy. If you are looking for a light video that will give you good quality, I would try MPEG-4 movie. These are really light and tend to give you nice quality. (image 3)
The two images are screengrab results from the two video. The first image is from the default AVI settings. Noticed I am also getting a crapy background and overall quality.
The second image if from the MPEG-4 video. Much nicer..
🙂Make sure you use Anti-aliasing to a High quality as well as this will help avoiding buzzing effect in your reflections and small details.
Hope that help! Please share the result with us once you figured it out!
