Can't play back 4k RED footage in real-time

Hey PrashantMac​, the 3rd test is in the same timeline as the 2nd, just move the playhead forward a few frames for the new instructions. You can use the default Adobe name for the project when it asks to convert, the exported file names will not change. Just make sure to delete any existing EXPORT files (only) before you run PPBM again, otherwise Adobe will rename the export files for you also.

I have an 8K R3D 6 second clip which I can playback on my 3-year old laptop at 1/8 resolution and after cleaning the Media Cache and Media Cache Files misses 1 frame but the second playback i get perfect playback

First, "real time playback" is nice when it works, but hardly necessary for most workflows. Second, depending on which format/codec out of that RED, any one computer may do better or worse than you'd "expect". Third, the way you work ... which effects you use, plus any 3rd party plugins & all, WILL affect how the playback works.

​

​This last is where a lot of people hit a wall ... they say plop Warp Stabilizer on multiple long clips off the bat ... then add other things. It can't do real-time, it keeps re-analyzing ... it's terrible! Well, yea, just do a test sequence to make sure that WS will work properly on a clip, maybe with your other expected effects applied also, but don't apply it in your working sequences until near the end of the editing process.

​

​Lumetri, especially in multiple layers, kills playback ...  also do it last. As with video denoising.

​

​So work smarter considering PrPro as it exists, not how you think or want it to be.

​

​And also ... download & run Bill Gehrke 's PPBM8 process, to get real good & hard data on how well that entire machine actually works within PrPro.
