It takes a lot of time to do all this comparisons, but I have a template for each type and everything is set when I open the template. Take a few screenshots and compare them to see if there are any difference. Same with the "use maximum render quality" and "render at maximum depth". If I can't see any difference from several images, I'll go for the faster one. Regarding the one or two pass rendering, I have tested this by doing one of each, grabbing a video screenshot of the exact same frame (easy in Premiere) and really pixel peeping the details in Photoshop. My "standard" UHD export settings is pretty much the same as the settings in your screenshot, except the "render at maximum depth", "use maximum render quality", the bitrate and frames per second (I'm in PAL land). But with the few adjustments you did, it's a lot faster, and it's always a compromise between speed and quality. The PCIe SSD disks are very fast today (up to more than 2GB/sec), but ram read/write speed is even faster (from about 12-14GB/sec for DDR4), so I still think your main bottleneck is the amount of ram. On my system I set the max memory to 58Gb as I said in the last post, and that would be like telling Premiere to "use whatever you want" (and very often the memory usage goes up to above 30Gb during rendering). If I understand it correctly, Premiere will then use more cache files instead of ram (writing files to disk instead of to the faster ram). Sounds good! The low memory usage is probably because you set Premiere to use max XX Gb for the rendering (Preferences, Memory). Is one pass bit rate encoding OK? Will it significantly effect the final video? I changed it to one pass and it cut the render time in half (which makes sense), down to about 6-1/2 minutes. I dropped it to 30 Mbps per your advice and that dropped render time from 17 minutes to around 13 minutes. I was rendering at 80 MBPS (must have been a default because I didn't set that). Memory monitor showed that I had 11 Gb memory free, It drops to a little under 7 Gb free while rendering. I added the name of the card to the list in the file "cuda_supported_cards.txt". If I render to about 60Mbps it will take around twice as long as a 30Mbps rendering.īut, take a look at the memory usage while rendering a UHD project, and you will probably see what's choking your system.Īnd yes, 18 minutes to render a 3 minutes timeline sounds slow. What about the bitrate for the exported projects. Ideally would be one drive for the OS, one drive for the cache and a third one for the project files. Another thing that is recommended (can't remember where I read it, but it seems reasonable), is to set the cache folder to a different drive than the OS. As I have read, speed is the most important for the rendering. Your CPU running at up to 4Ghz is probably good. ![]() Also FHD rendering easily goes up to between 20 and 30Gb, so your 16Gb of ram seems a bit low and could be the main bottleneck on your system. If I just drop a few UHD clips in the Premiere CS6 timeline and render, the memory usage usually goes up to 30-32Gb (during the rendering), so maybe you should consider a memory upgrade? I have 64Gb (DDR4) on my system and 58Gb available to Premiere, but I have never seen the memory usage above 32-34Gb for larger projects. But if it's enabled, I guess adding the correct name to the list wouldn't change anything. Before I added the card the hardware rendering option was disabled, so I'm a bit surprised that it's enabled with your card. I see on my system that the card "Quadro 4000" is listed, but not your card (Quadro P4000). The file is located in "C:\Program Files\Adobe\Adobe Premiere Pro CS6". I'm also using Premiere CS6, and with new graphic cards I had to add the name of the card to the list in the file "cuda_supported_cards.txt" to enable the use of hardware acceleration. This 3 minute 4k video took 18 minutes to render. Thank you for the response! Attached is a screenshot of the project settings with "Mercury Playback Engine GPU Acceleration" selected. ![]()
