Panasonic Camera DMC TZ60

Perjorative reviews, and belittling Apple staff will achieve nothing here, as we are just fellow users. You should also consider the larger implications as Google archives these open support communities, and your post will survive as long as Google.

Apple leadership and product teams do not participate here. You are probably aware that the Panasonic DMV TZ60 has Digital camera RAW support in Catalina, but that does not address video import. How were you "loading" videos prior to Catalina? If you were dependent upon Panasonic software to do that, I would suggest contacting Panasonic about updated software.

Generally this happens because you need a special CODEC for your videos and the old one was 32 bit. What format are the videos?

I suggest you use a card reader so that you can get the videos where they are easy to work with and figure out how to play them.

If this is the 64/32 bit issue, Apple has been warning the user base for years.

Yes, Apple reached $1.3 Trillion in December. Poor guys. :)

We have different definitions of "very sharply". If you think 6% is a very sharp decline since 2012, so be it. :)
