FFMPEG output upload to AWS S3 instead of local disk

Question

Currently, I'm outputting the result of FFmpeg process in the file locally on disk using the command

ffmpeg -i myfile.mp4 -an -crf 20 -vf crop=200:200 -s 800x600 newfile.mp4

Is it possible to store result newfile.mp4 directly on the amazon s3 bucket without saving the file locally? If so and if my s3 bucket address is s3://my.test.bucket how would you do it?

What have I tried so far?

ffmpeg -i myfile.mp4 -an -crf 20 -vf crop=200:200 -s 800x600 | s3://my.test.bucket

|: Invalid argument

ffmpeg -i myfile.mp4 -an -crf 20 -vf crop=200:200 -s 800x600 pipe: s3://my.test.bucket

Unable to find a suitable output format for 'pipe:' pipe:: Invalid argument
