Hi,

I am running the latest beta, works great for the most part. I noticed
the converted file size changes when using a Elgato turbo.264 HD.

I select "Universal", plug-in Elgato turbo.264 HD and convert a 367MB
TV Episode. iTunes shows the file size as 490MB.

Am I missing something obvious?

Thanks.

Billy.

Hi,
No. The turbo.264 usually creates files that are a lot bigger than necessary. This is mainly due to the fact that the turbo.264 is mainly geared towards fast encodings, not image quality or file size. If you do the same encoding without the turbo.264 hd you will see that the video will have considerably better quality and the file size is smaller, but the conversion will also take longer.

"Creation comes out of imperfection."

There's an old proverb in the video encoding world: "Speed, size, quality: pick two." It means that you always have to make a trade-off between the time it takes to encode a video, the amount of compression used, and the picture quality.
