Hi @croccld. Welcome to the FME Knowledge Center! Sharing a few more details will help the FME community help you. Please reply to this thread and provide additional details including:
- The version of FME you are using, including build number and edition
- A small sample of your data, or screenshots of the data in the FME Data Inspector
- A description of your expected output, with screenshots if possible
- Your FME workspace
- Your FME translation log file
- Any other information that may be useful to share

Hi @croccld,
I am currently experimenting with making videos with FME using rasters (here is an example where I made smooth transitions between frames - https://s3-us-west-2.amazonaws.com/safe-scenarios/Planet/video/smoothtransition.mp4), and in general, I work a lot with point clouds, so I am really curious about your scenario. Could you share a bit more details about it?
Here are some general tips you may find useful:
1) If you have a point cloud, you can easily rasterize it using ImageRasterizer - this way you get your separate frames.
2) We don't have some kind of a camera/viewpoint transformer yet, so you would have to transform the point cloud to get the different views - you can use Offsetter, Scaler, 3DRotator for this. This way you can create a sequence of different frames with ImageRasterizer
3) I use FFmpeg package to assemble videos from a sequence of frames - I call it from within FME with SystemCaller. Here is an example of the command line:
""C:\\Program Files\\ffmpeg\\bin\\ffmpeg.exe" -framerate 10 -i "C:\\Users\\dbagh\\smoothtransitionframes\\image_%5d.png" -y -codec:v libx264 -pix_fmt yuv420p -codec:a aac "C:\\Users\\dbagh\\video\\smoothtransition.mp4""
4) With our raster transformers, you can make smooth transitions between frames (when it makes sense) by using alpha band with RasterExpressionEvaluator and RasterMosaicker.
