Images of the milky way obviously give bad results. The result can be very good or also very poor, depending on the area of the cut object and the Then run the plug-in with appropriate values.

Use this plug-in in the following way: Copy the layer you want to work with, and cut out allĪreas with large objects, that are brighter than the background (nebulae, galaxies. Then a polynome of order 4 is fitted through these pivotal points, and the normalized valuesĪre written to the background gradient layer. This might be done several times, as specified by user. Omitting invisible parts and calculate the median.Ĭlip all values outside median +- n*sigma, where n is given by user. The plug-in uses the following strategy: Loop through a number of areas (size as give by user), Tries to create a layer containing the background for an artificial flat field. You can mulitply each pixel value by a given constant and then addĪ given constant (before calculating the mean value!).Ī preview widget lets you decide which is the best method for you. Mean value), and ignored (for all median mean values) if alpha channel is 0. The pixel values are weighted by alpha value (for arithmetic and geometric Sigma median is a median of all values inside You can choose, which method for the mean value you want:Īrithmetic, geometric, median, sigma median (1 or 2 pass). Optionally you can crop the image to the area, where the layers overlap.ĭe-rotation is done by selecting a second star during alignment process. Select the object you want to use for selection (from the first layer). This plug-in moves (and rotates) the layers that they overlap correctly.įor alignment by center of disk / brightness, select the area, where the star is, (aligned left, right and centered) (See for example here). Some information about your image, up to 2 lines at up to 3 positions Subtracts a dark frame from all layers naturally the dark frame shouldĭivides all layers by a flat field size issue as above.ĭraws a border (up to 2 different colors) around your images and on the bottom It doesn't provide a preview as the normal brightness & contrast plugin.īatch applies the normalize function (Layer->Colors->Automatic->Normlize) This script sets brightness and contrast to all layers Set brightness and contrast for all layers Some interesting plug-ins found on the internet:Ī plug-in to blend images with different exposure lengthes.Ī simple batch script to set overlay mode to all layers. I extracted frames 60 to 100, giving a 40 frame animation.To be useful for astronomical image processing.

Here's an example GIF I made, with GAP in GIMP, using the above steps, from a sample MP4 file available here. When the GIF export dialog appears, select the "Save as animation" option. To export the GIF click File > Export As (or if you are using GIMP 2.6.x use File > Save As), choose GIF as the file type. To see a preview of the animation click Filters > Animation > Playback This will open a new image window with the layers optimised. Optimise the animation using Filters > Animation > Optimise (for GIF). You can select 64 colours to try to keep the file size smaller. This will open a new image window in GIMP, with the video converted to layers.Īt this point, you may wish to scale the image to make it smaller, to keep the file size small.Ĭlick Image > Mode > Indexed, and choose Floyd-Steinberg (reduced color bleeding) as the dither method. Open the folder and you should see them in there. This is normal!Īt this point, the folder you have chosen as the output folder should fill with XCF files for each frame of the video. Note that this will show up as only 1 layer in the image window.

Also make sure the output folders are set to the same folder that your video file is in. Before you do this make sure your video file is in a folder on its own. Is there a default setting that I need to change somewhere to allow Gimp to covert the video into more than one frame? If not, has anyone else encountered this problem and found a fix?

So, I'm guessing that behavior may be an indicator of whatever the main problem is. However, if I click on the slider above the video preview in the "Video Range" screen, the "To Frame" and the "End frame" values reset to 1.In the Video Range screen, 180 is now the "End Frame" (which makes sense).Let's say I select "To Frame" and put in 180 (refer to screenshot below).Once I'm back in the main gimp screen, only one frame shows up in Layers. Selected "Create only one multilayer image".Set "To Frame" to 180 (I've tried using different ranges here).Went to Video > Split Video Into Frames > Extract.I downloaded and installed GAP (I pasted the resources I used below).I am trying to use Gimp (2.8) to convert an mp4 video to a gif.
