What codec options for getting video with alpha into Resolve

Hi guys -

I've been playing around with some MOV files that actually contain an alpha channel. I'm not 100% sure what codec they are using but I can link to them in Media Composer without any issue and MC recognizes the alpha channel.

Unfortunately Resolve does not even see these files. My question is, what codec options are there (under Windows) where Resolve will see the alpha channel? Is DNxHR 444 the only option (or an image sequence of TIFF files, etc.)?

Thanks in advance

You can usually see in the name of your available codecs that "a" is present (i.e. "argb", like uncompressed argb). It means alpha...
Now, I'm on mac so I personally use ProRes 4444 but you'll find an equivalent one in DNxH...

There’s a list of which codec can handle transparency (alpha) in the Resolve user manual.

I'll have to check that out. I'm finding that Resolve 15 b4 is being a bit finicky with alpha from DNxHR but it's hard to know which end of the pipeline is causing the issue.

Thanks

There were some reports about alpha issues in DNxHR if I'm correct.
There seems to be also "other' issues with alpha. Use search.
