Blender cannot work with a majority of the original AdobePDF blend mode types as they are strictly display referred and fail miserably when operating on scene referred imagery. From the AdobePDF spec …

In a properly encoded RGBA buffer, the RGB represents the quantity of emission of a given pixel "window", and the A represents the degree of occlusion of the geometry. The proper approach here is to …

While I cannot be certain, I strongly suspect that you have been greeted by one of the many reasons that PNGs are a cancer; their alpha values are unassociated by design, making them an absolutely wor …

The worthless format known as PNG. Render using half float 16 bit EXR. The issue is crappy unassociated alpha that is enforced with that abysmal format known as PNG. You could also use the "Convert …

While there are many subtleties and nuances to your question, the following should deliver reasonable results with equipment you may very well have around you or possibly borrow. Use a DSLR and use y …

There are potentially a few issues with either "Convert Premul", converting alpha, or a simple multiply across the channels, that may not be entirely obvious at first. It is a point of confusion in th …

You don't. You worry about frame accuracy during editorial, lock your picture (no further editing), and then commence post production work. At the point you have completed your edit, your motion pic …

It will depend on a number of things, not the least of which is your footage device. If your footage device can capture a log encoding, there’s a trivial way to get from the camera code value encoding …

As a loose outline, it’s much better to skip the ACES complexity and focus on what is required. ACES comes with its own entire set of issues, not the least of which is obfuscating the goals and the te …

Posterization and quantization are tricky beasts. You could do a simple quantization hack via a script to reduce the display referred output range, by dividing the display referred output by a value …

While cegaton's answer will work, I'd like to point out that your question is much more complex than what many folks might see at first glance and is a perfect example to examine the output view trans …

There is a heck of a lot of complexity here, not the least of which is background theory. First, you need to identify that a transform always happens between the scene referred domain and the display …

Most nodes should not. Cycles works under a scene referred rendering model, which means that there is no notion of white or black, but merely a range of values that traverse from some low value to a …

Don't use overs; there is no cache in the VSE Don't use heavy codecs. Try AVI-JPEGs or the like. Use precisely the resolution of the input; don't set the resolution percentage via the render resoluti …

Holograms are essentially like reflections, which are purely additive light without any occlusion. Try using the set alpha command to your image with zeros occlusion set in the alpha buffer. The RGB w …
