Q: Motion 5 Question
I have created a single letter logo with a camera for spinning. The duration of the project is 60 Seconds. Exported the project with Prores 4444 and Color+Alpha for the transparent background.
My question is with the above setting the file size is 480 MB which I feel very high. I tried all the other options but all other do not give me the transparent background. Is there any other way so that I can have the file size smaller keeping the transparent background ?.

You may feel that the file size is high, but that's just what it is. File size is going to depends on several things. What is your frame size? What is your frame rate? What is happening in the video?
ProRes 4444 is a higher bit depth format and basically what you need for transparency in movies. That alone is going to increase the file size. If you have a larger fame 4K vs 1920, that is going to increase the size. The higher your frame rate, the larger the size of your files. It can even come down to what is happeing in your video. For example, I created two versions of a 4K, 30fps, 60 second project with a single 3D letter spinning. In one, I used the default white texture, In the other I animated the surface color shifting throughout. The export to ProRes 4444 with no color change is 850 MB, the one with the color changes is 910 MB. This can probably be explained by the fact it is more efficient to compress the grayscale pixel values vs. color variations in the larger file. Simply changing the size of the text could probably impact the file size to some degree.
The ways to get smaller files with a codec that includes transparency would be to reduce the frame size and or reduce the frame rate. Of course these changes will come at their own cost. All that said, unless you are completely restricted in disk space, don't worry about it. Better have a larger, higher quality file to start with than something lower quality for some level of disk space storage saving.
