Verdict: Blender is an open source free video editor for Mac that offers 3D rendering. When rendering an animation with Blender it is advisable not to save it immediately as a movie, but as a sequence of images (in PNG format, as it is the one with the best quality / compression ratio and is compatible. In this tutorial for Blender (updated to Blender 2.8x) we will show you how to convert a sequence of images into an mp4 video for Youtube using the Video Sequence Editor (VSE).Also, keep in mind that GPU rendering is only available to users with AMD cards of GCN (Graphics Core Next) generation 2 or higher, so please check to make sure your machine’s internal setup is compatible before trying to use Blender with the GPU for rendering. The same basic process to turn on GPU rendering applies, but you will check OpenCL instead of CUDA or OptiX. CUDA and OptiX are exclusive to NVIDIA GPUs (GTX and RTX series, respectively) whereas AMD GPUs are supported by OpenCL. Once complete, you should be able to have the option to switch the rendering device to the GPU back in the Render panel of the scene.If you’re a Blender user with an AMD graphics card, the process may be a little different. Then, under Cycles Render Devices, check CUDA or OptiX.

It’s what helps the rendered scene look so realistic when compared to the viewport. You can learn more about ray tracing here, but simply put, light bounces are Blender’s way of simulating the natural properties of light and how it reacts, or bounces, on walls and other objects. This can also help with issues of random intense pixels of light, or “fireflies,” appearing in the render. By reducing the amount, the render can finish much faster. Clamping sets the threshold for the maximum allowable amount of brightness and intensity in the scene. 3.Decrease the Clamp Value SettingsAlso found in the Light Paths tab under Max Bounces is the Clamp Value settings. Transmission shouldn’t be changed too much as it will decrease the realistic quality of the final render. The default setting is at 12, but usually somewhere between 4 and 8 will give you the same amount of realism without taxing the GPU come rendering time.You can further fine tune the lighting setup by adjusting the individual light path types like Glossy or Diffuse, also found in the Light Paths section. Ps4 controller emulator macSince the GPU is only able to render one tile at a time, the fewer tiles the GPU has to compute, the quicker the process will become.In the Performance tab, also found in the Render Properties panel, you can change the tile size by X and Y dimensions. As some scenes render faster than others due to their resolution size, tiles are no longer based by count but by pixel size. Blender uses tiles to allow the CPU or GPU to focus on one specific piece of the image at a time, saving memory and reducing the chance of Blender crashing during the rendering process.Blender now allows you to change the dimensions of these tiles. Those patches of information are called tiles. 4.Increase the Render Tile Size and AmountDuring a typical render, you will notice that the image will begin processing in patches in the render viewport. The defaults are set to 128 and 32, respectively, but these won’t do if you’re looking for a final rendered image. The more samples you have, the clearer the final render.In the Render Properties panel, you can define the number of samples in the Sampling tab using the Render and the Viewport values. Samples make up the noise that appears in the rendered image. 5.Decrease the Sample AmountThe most obvious, but most time-consuming aspect that needs to be addressed is the sampling count. Conversely, when using the CPU to render, the best way to a faster render is to make the tile size smaller. Outlook sync pending for this folder macThere’s no need to exhaust the GPU with processes that people won’t be able to notice. Experiment with sample rates and see how you can get the best image with the fewest samples. However, unless you are a purist of pixels, most people won’t notice if you process the render with a sample rate of 2,000.If you are just rendering a still scene, this may not be much of an issue for you, but if you are rendering an animation, those samples will add up very quickly and significantly slow down the process.
