Render bar turns red after scaling video in 2020

[vanze]

I recently updated to Premiere 2020, now when I have 2 videos and put one on top of the other and scale it to 50% for example, render bar turns red and then I have to waste time doing 'render effects in to out' and I didnt have to do it in 2019 version, bar was staying yellow. Is there any option I missed?

In your version it now has to be rendered. I am curious what is your operating system? Did you know that Catilinia MacOS 10.15 will only run 64 bit video natively (adobe will continue to support the older formats). This means that now Adobe does the heavy lifting for all of those video formats.

I have replicated this behaviour. Scaling a Bars & Tone clip to 50% plays back without rendering in 2019 and 2018, does not do so in 2020. 

None of the players drop frames, so the red bar seems to be in error. 

I believe this is a bug.

I just saw that project settings were set to software render instead of GPU acceleration, now it works fine

Cannot reproduce on windows.

Please post computer specs, OS build,

My windows rig replicated it 1903 z820 M4000 96GB. Bars & Tone scaled to 50% in an identical sequence.

Working OK for me, yellow bars, plays fine. With one or both scaled to 50 or any %.

Xeon processors, no? Do they support QuickSync or not?

Thanks,

Kevin, why would QuickSync be in use for this render? 

Xeon processors do not support QuickSync as they don't have the GPU fabric

I have confirmed with Adobe phone support that all Xeon processors are supported. 

If you have information about Xeon processor requirements, please let me know.

New system requirements, now. What's your CPU? How does it compare with current system requirments?

Thanks,
Kevin
