Sony XAVC-HS with Catalyst Prepare stabilization plugin workflow - proxy or optimized media?

[Guest]

I bought a new Macbook M2 Max and try to edit Sony XAVC-HS Footage in UHD 10bit 422 from my Sony FX3 (Same codec as A7SIII) with the Sony Catalyst Prepare Plugin. So I am able to stabilize my clips in post if necessary. Now the codec not an easy one to process and the Sony Plugin seems to slow down everything even more, although stabilization is not even activated yet. I think I will not be able to edit a timeline for a 30 minute Documentary with original media. So I tried to switch to proxies. They work fine as expected BUT I cannot see the Sony stabilization effect anymore. When I activate proxies the stabilization gets disabled in the viewer. So I can edit my documentary with proxies but in the end when I have to grade, apply effects and stabilize I will have to switch back to originals and the system will get so slow that I will not be able to finish the whole documentary. How can I prevent that? Is there a way to use "optimized media" instead of proxies with metadata? I tried to convert XAVC-HS to XAVC-I in Sony Catalyst Prepare but then all my stabilization metadata is deleted. How can I use a lightweight codec and still be able to see stabilization results in the viewer? Thanks for your help!

Does anyone have experience with XAVC-HS and the Catalyst Plugin??

I think it would be safer to record in XAVC-I so I can edit with an Intra codec and have all the metadata available.

But in the forums I get very different opinions about the performance of XAVC-I UHD 422 10 Bit in Premiere, so I am not sure if its worth investig lots of money in those expensive CFexpress Type A cards.. Anyone here? Is the performance comparable to Prores? (I guess its not)

It is a bit late to answer but, I would say that since I bought the pergear Type Cards I only record on Intra, slog3 cine, premiere still needs proxies (amd3750x and rtx3080/8gb 64gb ram)  any time you scale or color grade, soooo.... I always use proxies, but for color grading in particular you better do it on the actual footage, you may find surprises at the end if not.

So as far as I can see, there is nothing like "optimized media" in premiere right?

Only Proxy Media is available or transcode before import..

Premiere has workflows for proxies, but not a Resolve style "optimized media" perzactly.

You can specify a preview format/codec, then select some or all clips on a sequence, and make preview files.
