2022年12月15日 · EXR for more editing freedom! PNG for previews and if you don't plan on editing it but I'd always recommend a bit of editing

2020年4月10日 · PNGs can't handle pixels that are emissive and transparent at the same time because PNG does not support associated alpha transparency. You are on the right track using EXR, what you need to understand is that EXRs are exported as linear information (meaning no "gamma curves" are applied to make them display nicely on a monitor).

2019年8月11日 · In the evaluated data OpenEXR consistently beats PNG in encoding speed. Furthermore, OpenEXR produced smaller files at equal bit depth for all codecs (excluding None which doesn't compress). The lossy codec DWAA produces smaller files than PNG even at 32-bit.

2023年5月3日 · Always render in HDR (exr, etc) for any final frames. You want the higher bit depth to give you more freedom to do final color tweaking and adjustment. In theory a png is fine, as many movies and projectors aren’t hdr anyways.

2013年11月2日 · PNG: PNG (Portable Network Graphics) is a lossless format, meaning that the data can be reconstructed exactly as it was before being compressed. PNG supports true color color depth. Blender also supports 16 bit PNG, which gives a larger range of possible colors.

2024年12月31日 · EXR vs. PNG. Color Depth: PNGs typically support 8-bit and 16-bit color depth, while EXR files can support 32-bit floating-point color. Use Case: PNG is often favored for web graphics due to its lossless compression and transparency support, while EXR is specialized for rendering and effects. EXR vs. BMP

2021年8月11日 · EXR retain more dynamic range and more information, so it gives you more flexibility when compositing. Note that if you're not doing pro work, PNG are probably fine, I very rarely use EXRs myself. EDIT: To add to this, a usual use-case for EXR is …

2024年3月25日 · PNG (Portable Network Graphics) and EXR (OpenEXR) are both popular image formats, yet they serve distinct purposes and exhibit notable differences. PNG, a lossless compression format, is widely used for web graphics and digital images.

2021年9月2日 · .EXR is a data-file format, while .PNG is a image-file format. “Entirely different purposes.” EXR was created by Industrial Light & Magic(!) expressly for this purpose. And they tell me that the Blender Foundation(!!) was the original origin of the “multi-layer” extension to the format, which of course was immediately adopted into the ...

2021年5月6日 · PNG is considered a forbidden file format (as elaborated further down), not prone to a “subjective opinion”, but a technically proven requirement. EXR concerns as much solo-individuals as established studios.
