HSV Adjust TOP

Summary

The Movie File In TOP loads movies, still images, or a sequence of still images into TOPs. It will read images in .jpg, .gif, .tif, or .bmp format. It will read movies in QuickTime's .mov format, .mp4, .mpg, .mpeg, .avi, .wmv, .dpx, Cineform and Hap Q formats (including Hap Q with Alpha). It also supports some .swf and .flv Flash files as well as DXT1, 3, and 5 compressed .DDS files. Images and movies can also be fetched from the web by using http:// to specify a URL.

For a complete list, see File Types.

Examine the state of a Movie File In TOP by attaching an Info CHOP to it (see below on Info CHOP). This will show static info like movie length, resolution, frames per second, and whether there is audio in the file. It also shows dynamic information like movie open status, current frame, readahead frames and queue size, dropped frame count, CPU decode time and GPU upload time.

Parameters - Common Page

Output Resolution outputresolution - ⊞ - quickly change the resolution of the TOP's data.

• Use Input useinput - Uses the input's resolution.

• Eighth eighth - Multiply the input's resolution by that amount.

• Quarter quarter - Multiply the input's resolution by that amount.

• Half half - Multiply the input's resolution by that amount.

• 2X 2x - Multiply the input's resolution by that amount.

• 4X 4x - Multiply the input's resolution by that amount.

• 8X 8x - Multiply the input's resolution by that amount.

• Fit Resolution fit - Grow or shrink the input resolution to fit this resolution, while keeping the aspect ratio the same.

• Limit Resolution limit - Limit the input resolution to be not larger than this resolution, while keeping the aspect ratio the same.

• Custom Resolution custom - Directly control the width and height.

Resolution resolution - ⊞ - Enabled only when the Resolution parameter is set to Custom Resolution. Some Generators like Constant and Ramp do not use inputs and only use this field to determine their size. The drop down menu on the right provides some commonly used resolutions.

• W resolutionw -

• H resolutionh -

Resolution Menu resmenu - A drop-down menu with some commonly used resolutions.

Use Global Res Multiplier resmult - Uses the Global Resolution Multiplier found in Edit>Preferences>TOPs. This multiplies all the TOPs resolutions by the set amount. This is handy when working on computers with different hardware specifications. If a project is designed on a desktop workstation with lots of graphics memory, a user on a laptop with only 64MB VRAM can set the Global Resolution Multiplier to a value of half or quarter so it runs at an acceptable speed. By checking this checkbox on, this TOP is affected by the global multiplier.

Output Aspect outputaspect - ⊞ - Sets the image aspect ratio allowing any textures to be viewed in any size. Watch for unexpected results when compositing TOPs with different aspect ratios. (You can define images with non-square pixels using xres, yres, aspectx, aspecty where xres/yres != aspectx/aspecty.)

• Use Input useinput - Uses the input's aspect ratio.

• Resolution resolution - Uses the aspect of the image's defined resolution (ie 512x256 would be 2:1), whereby each pixel is square.

• Custom Aspect custom - Lets you explicitly define a custom aspect ratio in the Aspect parameter below.

Aspect aspect - ⊞ - Use when Output Aspect parameter is set to Custom Aspect.

• Aspect1 aspect1 -

• Aspect2 aspect2 -

Aspect Menu armenu - A drop-down menu with some commonly used aspect ratios.

Input Smoothness inputfiltertype - ⊞ - This controls pixel filtering on the input image of the TOP.

• Nearest Pixel nearest - Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native Resolution.

• Interpolate Pixels linear - Uses linear filtering between pixels. This is how you get TOP images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native Resolution.

• Mipmap Pixels mipmap - Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail.

Fill Viewer fillmode - ⊞ - Determine how the TOP image is displayed in the viewer.

NOTE:To get an understanding of how TOPs work with images, you will want to set this to Native Resolution as you lay down TOPs when starting out. This will let you see what is actually happening without any automatic viewer resizing.

• Use Input useinput - Uses the same Fill Viewer settings as it's input.

• Fill fill - Stretches the image to fit the edges of the viewer.

• Fit Horizontal width - Stretches image to fit viewer horizontally.

• Fit Vertical height - Stretches image to fit viewer vertically.

• Fit Best best - Stretches or squashes image so no part of image is cropped.

• Fit Outside outside - Stretches or squashes image so image fills viewer while constraining it's proportions. This often leads to part of image getting cropped by viewer.

• Native Resolution nativeres - Displays the native resolution of the image in the viewer.

Viewer Smoothness filtertype - ⊞ - This controls pixel filtering in the viewers.

• Nearest Pixel nearest - Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native Resolution.

• Interpolate Pixels linear - Uses linear filtering between pixels. Use this to get TOP images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native Resolution.

• Mipmap Pixels mipmap - Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail. When the input is 32-bit float format, only nearest filtering will be used (regardless of what is selected).

Passes npasses - Duplicates the operation of the TOP the specified number of times. For every pass after the first it takes the result of the previous pass and replaces the node's first input with the result of the previous pass. One exception to this is the GLSL TOP when using compute shaders, where the input will continue to be the connected TOP's image.

Channel Mask chanmask - Allows you to choose which channels (R, G, B, or A) the TOP will operate on. All channels are selected by default.

Pixel Format format - ⊞ - Format used to store data for each channel in the image (ie. R, G, B, and A). Refer to Pixel Formats for more information.

• Use Input useinput - Uses the input's pixel format.

• 8-bit fixed (RGBA) rgba8fixed - Uses 8-bit integer values for each channel.

• sRGB 8-bit fixed (RGBA) srgba8fixed - Uses 8-bit integer values for each channel and stores color in sRGB colorspace. Note that this does not apply an sRGB curve to the pixel values, it only stores them using an sRGB curve. This means more data is used for the darker values and less for the brighter values. When the values are read downstream they will be converted back to linear. For more information refer to sRGB.

• 16-bit float (RGBA) rgba16float - Uses 16-bits per color channel, 64-bits per pixel.

• 11-bit float (RGB), Positive Values Only rgba11float - A RGB floating point format that has 11 bits for the Red and Green channels, and 10-bits for the Blue Channel, 32-bits total per pixel (therefore the same memory usage as 8-bit RGBA). The Alpha channel in this format will always be 1. Values can go above one, but can't be negative. ie. the range is [0, infinite).

• 16-bit float (RGB) rgb16float -

TouchDesigner Build: Latest\n2021.100002018.28070before 2018.28070

An Operator Family that creates, composites and modifies images, and reads/writes images and movies to/from files and the network. TOPs run on the graphics card's GPU.

An Operator Family which operate on Channels (a sequence of numbers (Samples)) which are used for animation, audio, mathematics, simulation, logic, UI construction, and data streamed from/to devices and protocols.

The Graphics Processing Unit. This is the high-speed, many-core processor of the graphics card/chip that takes geometry, images and data from the CPU and creates images and processed data.

The width and height of an image in pixels. Most TOPs, like the Movie File In TOP can set the image resolution. See Aspect Ratio for the width/height ratio of an image, taking into account non-square pixels.

The viewer of a node can be (1) the interior of a node (the Node Viewer), (2) a floating window (RMB->View... on node), or (3) a Pane that graphically shows the results of an operator.

A CHOP outputs one or more channels, where a channel is simply a sequence of numbers (Samples), representing motion, audio, etc. Channels are passed between CHOPs in TouchDesigner networks. Channels can be Exported to Parameters.
