I need to find a good way to finish my projects in Premiere in post:
The whole project is whot in XAVCHS, which means H265 UHD 422 50p 10bit and I need to deliver 1080i 25i in the end. I need more quality for post production and be able to zoom in later.
Last time I transcoded everything to Prores HQ UHD 50p but it takes up LOTS of TB SSD space and still has performance issues in the 25i hd timeline, so I was hoping I could work with proxies.
So this time I created Prorex proxy UHD in Adobe itself and it kind of works, at least as long as original media is connected as well - Iast time when original media went offline part of the audio could not be relinked - I will try when the project is finshed.
Now when the project is almost finished going back to originals is not an option - even on an apple M2 max with 32 gb of ram premiere is not able to playback prores proxy smoothly when downsampling from 50p uhd to 25i HD in the sequence. Thats an issue I havent had with any other editing application (avid, resolve, fcpx). Usually the m2 max has lots of performance to downsample prores even with a little lumetri colour correction applied. (no other effects, sometimes just a blur on faces or license plates)
But now I notice that evend the proxy workflow.
Now I tried "render and replace" which is kind of annoying when having a colour managed workflow and transcoding through the "media manager" shifts a lot of keyframes like added blur for some faces.
So I guess the only "robust" workflow is to work with proxies - and those sometimes cause audio issues.
I think it would be better to work with prores 422 HD instead of prores proxy UHD (prores proxy HD is definitely too low quality), but only prores proxy is available - so I need to create a custom ingest preset and then again premiere (or AME) wants me to define the audio channel configuration - it does not adapt dynamically to the audio configuration of the source clips.
So is there any way to create a custom ingest (proxy) preset that adapts to the audio configuration of the source files?
And is the issue known that even Prores UHD conversion to 25i HD has such a massive performance degradation?
BTW - I am working with a blackmagic ultrastudio mini monitor breakout box - but in 50p there are no issues.
Whats our recommendation for the best workflow? Using render and replace? Using HD proxies? Why is premiere so slow always dropping frames in interlaced timelines?
