# Image Settings ![Image Settings](/assets/md-image-settings.png) ## File Creation ### Naming Mode In the Naming Mode feature, you have the ability to designate your preferred `Marker IDs` and establish a distinctive nomenclature for image file names. By [!badge text="Default"], the **Marker Data** function adopts the Marker's `Timeline and Timecode` as its primary `Marker ID`. To illustrate, if the timeline were denoted as `Demo V1`, the `Marker ID` generated by **Marker Data** would be `Demo_V1_Timecode`. This identifier is then employed for the corresponding image file name. Alternatively, you can opt for `Name` or `Notes` as your preferred `Marker ID`, catering to diverse workflow requirements. Such choices are particularly advantageous for the creation of a Visual Effects (VFX) Database, as outlined in more detail [here](/faq.md/#what-constitutes-an-optimal-methodology-for-the-nomenclature-of-visual-effects-identification-vfx-ids-within-a-workflow). In the cases of `Name` and `Notes`, it is advisable to input unique text values to ensure distinctiveness. In instances where text values are identical, **Marker Data** autonomously appends a numerical suffix to the filename for differentiation. ![Selecting Naming Mode](/assets/md-image-settings_01.png) Select your desired Naming Mode. - **Timeline and Timecode** [!badge text="Default"] - **Name** - **Notes** ### Marker Source Select your desired Marker Source. - **Marker** [!badge text="Default"] - **Marker and Captions** - **Caption** !!!warning Warning An error occurs during the extraction process when the `Naming Mode` is configured to `Notes`. This setting is incompatible with the `Marker Source` option when it is set to either `Marker and Captions` or `Captions`. !!! ### Image Format By [!badge text="Default"], the **Marker Data** application undertakes the extraction and exportation of image data in the `PNG` format, preserving still frames. You have the flexibility to opt for either the `JPG` format or, alternatively, animated `GIFs` in the export process. Select your desired Image Format. - **PNG** [!badge text="Default"] - **JPG** - **GIF** !!!info Info The selection of the `GIF` format may result in a substantial increase in the file size of the exported images. !!! ## Image Size ### Default In the majority of workflows, the [!badge text="Default"] parameter would be sufficient. You have the ability to customise your image dimensions to a greater extent by opting for either the Size parameter or specifying the Width & Height values. ### Size (%) The [!badge text="Default"] Configuration assigns a size percentage of `100` to both the `PNG` and `JPG` Image Formats. Conversely, for the `GIF` format, the [!badge text="Default"] size percentage is established at `50`. To illustrate, in the scenario where the original exported video file possesses dimensions of `1920 x 1080`, adjusting the Size (%) parameter to `50` would yield extracted images with dimensions reduced to `960 x 540`. ### Width By [!badge text="Default"], the width selection feature is deactivated in **Marker Data**, with the application automatically adopting the precise dimensions from the exported video file. Activating this option allows you to manually constrain the image width while preserving its inherent aspect ratio. ### Height By [!badge text="Default"], the height selection feature is deactivated in **Marker Data**, with the application automatically adopting the precise dimensions from the exported video file. Activating this option allows you to manually constrain the image height while preserving its inherent aspect ratio. !!!info Info We advise against setting the Size (%) value to exceed `60` when working with the `GIF` Image Format. !!! ## JPG ### Quality You have the flexibility to designate distinct `Quality` values for the `JPG` Image Format, with lower values resulting in reduced file sizes. Notably, the `Quality` setting is initially inaccessible, appearing greyed out by [!badge text="Default"], and exclusively applicable to the `JPG` format. The [!badge text="Default"] setting for Quality is established at `100`. ![Quality set to 100](/assets/md-image-settings_02.jpg) ![Quality set to 10](/assets/md-image-settings_03.jpg) !!!info Info To conduct a thorough analysis of file size and compression, you can right-click on the above mentioned images and subsequently save them for comparative evaluation. !!! ## GIF ### FPS The Frames per Second (FPS) parameter is initially disabled by [!badge text="Default"], appearing greyed out. This functionality is exclusively applicable to the `GIF` Image Format, with a [!badge text="Default"] value set at `10`. ### Span (Sec) The Size (%) parameter is initially disabled, displaying in a greyed out state by [!badge text="Default"]. This option is exclusive to the `GIF` Image Format, with the [!badge text="Default"] value pre-set at `2`. ![GIF with 10 FPS and 2 Sec Span](/assets/md-image-settings_04.gif) ![GIF with 15 FPS and 3 Sec Span](/assets/md-image-settings_05.gif) !!!info Info We advise against configuring the Frames per Second (FPS) value to exceed `15` and caution against setting the Size (%) value to surpass `3` when working with the `GIF` Image Format." !!! !!!info Info To facilitate a comprehensive file size comparison, you can right-click on the images above and save them to your local computer. !!!
## Swatch ![](/assets/md-image-settings-swatch.png) ### Enable Swatch Enable the checkbox to embed colour Swatch Palette into extracted images. !!!info Info For both Notion and Airtable Export Profiles, when `GIF` is selected as Image Format, Swatch Palettes will be extracted as a separate `.jpg` file. !!! !!!info Info Embedding extracted images with a Color Swatch Palette is not supported for Excel Profile. !!! ### Algorithm Select your desired Swatch Algorithm. ==- Euclidean [Euclidean](https://en.wikipedia.org/wiki/Color_difference#Euclidean) algorithm calculates difference in RGB colour space. ![Euclidean](/assets/swatch-Euclidean.png) ==- CIE76 [!badge text="Default"] [CIE76](https://en.wikipedia.org/wiki/Color_difference#CIE76) algorithm calculates difference in Lab colour space ![CIE76](/assets/swatch-CIE76.png) ==- CIE94 [CIE94](https://en.wikipedia.org/wiki/Color_difference#CIE94) algorithm is an improvement of CIE76, it calculates the difference in the Lab colour space. Slightly slower than CIE76. ![CIE94](/assets/swatch-CIE94.png) ==- CIEDE2000 [CIEDE2000](https://en.wikipedia.org/wiki/Color_difference#CIEDE2000) algorithm is the most accurate colour comparison algorithm in the Lab colour space. It is significantly slower than its predecessors. ![CIEDE2000](/assets/swatch-CIEDE2000.png) ==- CMC [CMC](https://en.wikipedia.org/wiki/Color_difference#CMC_l:c_(1984)) algorithm calculates the difference in the HCL (Hue, Chroma, Luminance) colour space. ![CMC](/assets/swatch-CMC.png) === !!!info Info The sequence and presentation of results on the colour swatch strip may vary with each iteration owing to the inherent randomness of the algorithm. !!! !!!info Info The swatch strip can accommodate a maximum of 14 colour chips. However, the actual number displayed may be fewer, depending on the dominant colours within the image and their proximity to one another. If the delta between colours are minimal, the algorithm may amalgamate similar shades into a single representation, resulting in fewer than 14 distinct colours on the swatch strip. !!! ### Accuracy Select your desired Accuracy. - **Low** - **Fair** - **High** [!badge text="Default"] - **Best** Adjusting the Accuracy setting impacts the swatch analysis during image extraction. Selecting `Low` accelerates the analysis process, albeit at the cost of precision. Conversely, opting for `Best` ensures a higher degree of accuracy, though this choice extends the processing time required for image extraction. ### Exclude Black Enable the checkbox to ignore `Black` from Swatch. ### Exclude Grey Enable the checkbox to ignore `Grey` from Swatch. ### Exclude White Enable the checkbox to ignore `White` from Swatch.
