Here’s a trick to convert multiple video files with Handbrake.
Note – with Version 10 of Handbrake. the screens looks slightly different, but the process is still the same.
First off, create a folder to only hold the videos you want to convert and then move all those files into that folder.
Now in the Handbrake program choose Source – Folder and then select the folder you just created when you browse. Make sure you don’t open the folder, just select the folder.
Handbrake will now go through the folder and select all the files in the folder and list them as Titles.
At the Add to Queue box- CLICK THE DOWN ARROW and click on the Add All option. (thanks AK for this tip.)
Now you can just run your Queue and wait for all your files to be automatically converted.
