Several people have sent comments to the e-list about file conversions.
Here are some points:
David Burrows: "With videos for G321/G324 in mind, can anyone suggest (ideally freeware!) software for this? Haven't found any that convince so far!
Also, any recommendations for sound/video file converters?"
Gary seal: "File converting - FormatFactory does the job and is free."
Hannah Cayton: "For screen recording on a Mac, I use Snapz Pro. It was around £60 when I bought it a couple of yeas ago. Not free, I know, but it works really well for recording moving image and demonstrations.
keepvid.com is great was grabbing videos from YouTube, offers you several formats and file sizes, and is free."
