You should write LibraryLink paclet using https://github.com/WolframResearch/LibraryLinkUtilities. Demo paclet: https://github.com/WolframResearch/LibraryLinkUtilities/tree/master/tests/Demo
This is what I get when I evaluate Video for the first time in 13.0 for Windows: ![Install FFmpeg][1] [1]: https://community.wolfram.com//c/portal/getImageAttachment?filename=ffmpeg13.0.png&userId=32329
Thank you for reporting. We will try to fix this issue in the next version. Meanwhile, you can use `AnimationVideo` introduced in 12.3.
Or ``` Range[100, 0, -1] ```
This is how you should use it: In[1]:= img = RandomImage[1, {200, 300}, "Byte", ColorSpace -> "RGB"]; In[2]:= FileSize[Export["out.jp2", img, "ImageEncoding" -> "JPEG2000", CompressionLevel -> #]] & /@ {0.2, 0.5, 0.8} ...
Using ColorSeparate / ColorCombine is about 4x faster than your third solution: In[1]:= testImage = Image[ExampleData[{"TestImage", "Mandrill"}], "Real32"]; In[2]:= RepeatedTiming[ r1 = ColorConvert[ ImageApply[ ...
PNG uses different compression algorithm than JPEG2000, but here are some ideas that you can try. Input file: In[1]:= file = "ExampleData/girl.jp2"; In[2]:= i = Import[file]; In[3]:= FileSize[FindFile[file]] Out[3]=...
Conversion of `Graphics` to `Image` usually requires a rasterization and unfortunately it is the case here. `Image` constructor internally calls `Rasterize` when the input argument is a `Graphics` object. The only exception is...
This memory leak will be fixed in version 12.0. In 11.3 you can use animated GIF or PNG.
QuickTime.exe was removed in version 11.3.0 for Windows, but ```Internal`$VideoEncodings``` should still work correctly and should return `{"H264"}`. This bug will be fixed in version 12.0.
