My PC's is Windows 10 64-bit, CPU- AMD Ryzen 7-1700 8-core 3000Mhz. GPU - nVidia GeForce RTX-2070 8Gb & 16Gb of DDR4 3200 RAM
I used all the recommended Vegas Pro 19 Project Settings for a 9 minute UHD HDR slideshow. Each photo was a uncompressed 16bit .pdf 5500x3667px & all photos Properties were set in Vegas Pro 19 to Color Space Rec.2020 / Color Range to Full. Some panning was applied to most photos to add motion to the video & text to identify the photo's location.
Here's where it got funny. I could never get a finished render using MAGIX HEVC/AAC MP4, HDR10 VBR 80,000,000 max / 40,000,000 min with Options / Settings / GPU video acceleration to ON. The render would crash at about 2/3 finished.
But, when turning GPU video acceleration setting to off, the render not only completed 100%, it was about 50% faster. The finished HDR slideshow looked great in HDR on our OLED TV!
Any idea what I missed?
