Improve file size help please
Hello, I've got this batch file script I use to convert .mp4 files to v8 .webm format. However, I notice the newly created .webm file size is usually quite a bit bigger than the original, which leads me to believe there is something set in the script which is unnecessary or wrong. I don't know a lot about it, but are there any specific things you recommend changing, so I will have comparable quality to the original, but not inflated file size?
Thanks in advance.
