Nowadays, more and more people own Blu-ray Discs which provide high quality and add more fun to our daily life. However, the first problem we concerned, is space – a bluray movie can take up to about 50GB of space on your server. While harddrives are cheap, and space is economical, a 2TB drive can really only hold 40 movies if they are left uncompressed.

To compress the file size into video under 25GB, what you should do is changing the figures of these options to be smaller only. Look at the target file size, keep it under 25GB. One more thing you must be sure that there will be some quality loss if you compress them to be a much smaller size, which means you’d better make a balance between the size and image quality. At least the output video quality should be acceptable by yourselves.

Step 4: Start compression and conversion

As long as the former three steps are set well, then you can click “Convert” button to start Blu-ray ripping, at the same time, the compression task of Blu-ray file size is underway as well. Once finished, you can find out the output files via clicking “Open” button. After that you can do whatever you like with the compressed Blu-ray files.

Choose the number of copies you want to burn – each time a disc is complete; you will be prompted by Toast to insert another disc. Hit the big red Copy button, and the disc burning will begin!

Now insert this Blu-ray to your BD player and star enjoying!
