In a 4 drive NAS (synology), is it possible to setup two drives in raid 1 and the other two in non-raid?

Purpose is to have some level of redundancy yet have centralized storage for movies that can live without backup

yes but please don't consider the raid1 a self backed up drive. Raid 1 will survive a single drive failure but will not protect you from user error (opps I deleted the partition), viruses, file corruption, system-wide hardware failure like a nearby lightning strike that kills all 4 drives and the NAS..., environmental disasters (fire, flood, malicious pets...), theft....

Only an unpowered off-site backup would survive some of these events.

Have a look at the following article about the different levels of Raid. Raid 0 you shouldn't consider due to the nature of losing half your data should a Raid 0 Array fail. Raid 1 if it's going to be used for home use is safe, it's a much better option than raid 5 and has a low risk level (Raid 1 has a low Risk Level as this Article from Wikipedia will show you).

Also have a look at the following YouTube Video
