xitor:Can say that it doesn't fix the issue with a video dropped on the timeline and reversed still does not export.    What video dropped on the timeline. I drag and drop videos all the time. I haven't done reverse though so can't comment.  Did an export of my last video, and didn't noticed any speed improvement, but looking ...

JudyR:If so ... is it fully backward compatible with Studio 9 or what are the limitations for my former projects done under Studio 9. 17 year difference between the software in addition to several Operating System upgrades and all that goes with it. 

Yes, quite a list. And I am sure not fully comprehensive either. A lot of what is posted in the list didn't affect me personally. The Ryzen PC issue I haven't seen (honestly I haven't been editing for a while..other more pressing issues). MyDVD I do not use, I seldom use NBFX transitions, etc. I have noted a performance increase in exporting, ...

It has happened to me a couple of times, but on a restart of the software, it's always started right up. What I've seen posted here doesn't affect everyone, which makes troubleshooting very difficult considering that there is an infinite number of computer soft/hardware configs and usage. Patches and fixes don't happen over night. And then there ...

Ok Martin... here is the patch list.Clarify usage for RedEye correctionMavic drone video jerks/jumps in exported fileTransitions and effects added from closed ''stack'' are No Preset, not default setting Rendering very slow in 24.1, ok in earlier 24 or in 23. Need hotfix for 24 External preview goes black during editingTimeline+Export ...

If you have 24, load up a project, trim it down a bit so you can do a render test. For timeline rendering, you have to have Optimization set to ''0'' and make sure you delete Rendered files. Then turn the Optimization to 100 and start the stopwatch. Then Export.  Do the same thing in PS25. 

I thought it was going to fix the USB plug/unplug issue.... well, it didn't on my computer. Plugged in my 5TB USB 3 drive and PS disappeared. Also, I think performance? I did some tests and it is faster! I haven't hammered the patch yet, but have started with 4K 422 10bit 24P. I even has ProRes 422 HQ, 24P 185Mb/s with screen ratio ...

I have SS songs scattered over a variety of disks on my computer. My suggestion would be to contact tech support at Smartsound. Frank is very helpful with matters like this. 

For the cost of everything you will be getting, if you don't have them, this is a great deal. Just understand that it will stress your hardware a lot.  

L.Nieste:Same problem here.  Have you tried the suggestions?
