Is IMX30 a better source/master for compressing/transcoding vs uncompressed AVI/Quicktime?

Hi, I posted this question on the Premiere Pro forum, and I was hoping to get the opinion of the people in the compression forum. See, I just came across this requirement from a digital delivery service for TVCs. They ask for an IMX30 to be uploaded on to their cloud, which then gets recompressed/transcoded to different file formats such as DVCPro50, DV25, IMX50, etc, and sometimes even get dubbed onto a BetacamSP tape.

I'm sort of questioning this process as I've always believed that starting from the best source, such as an uncompressed file, is always better than starting with a lossy codec such as IMX30.

Here's a link to the complete article:

Am I right in thinking this article is more of a marketing move rather than an attempt to be technicality accurate and transparent? Would appreciate inputs. Thanks

Those are all older standard def formats and not great quality by modern standards.

Is this for TV /Cable (not public access)?

Common delivery has been MPEG2 Program or Transport Streams.
Sone now accept AppleProRes and DNxHD (I believe) if you have the bandwidth.
