Why don't versions after FF4.7 make files as small as 4.7 using optimal Qual and size settings?

Question

Since v4.7, when I run FF using the Optimum Quality and Size setting (I always convert to .mp4) I end up with a converted file (even from mp4 to mp4) larger than I get using v4.7 --- often as much as double the size. Are there settings in later versions (currently 5.8.1.0) that will produce converted files as small as 4.7 does or is this a lost cause? I love FF, have used it for years, and would prefer to use the latest version if possible, but not at the expense of ending up with much larger file sizes.

Answer 1

The file size discrepancy you are experiencing in FormatFactory after version 4.7 might be due to changes in the encoding algorithm or settings. It is possible that the newer versions prioritize other factors over file size optimization. You can try adjusting different settings in the later versions to see if you can achieve smaller file sizes while maintaining satisfactory quality. It is recommended to consult FormatFactory's documentation or support for specific guidance on achieving desired file sizes.
