I would have one / ext4 partition for everything. (You may want a
separate /home, if you plan on reinstalling OS while keeping /home data,
but, on the other hand, one should also have daily backups to get /home
back from.)
If your new system uses EFI, then you'll also need a /boot_efi
partition, 200MiB, FAT32, bootable.
If I had swap, I would put it on SSD.

With these sizes they would go into SSD /.

I don't know how much video editing can benefit from btrfs, but for
archives I would use two HDDs, and have btrfs partitions in btrfs-raid1
volume to protect from bit rot (see for example [1]).
