ps1 issue 6: echo w/ extra parameters

[bturkus]

running echo without options works, but when i run it like this seems to fail:

./echo.ps1 -s [file] 0.2 5 3

[nkrabben]

It doesn't like any mode that uses gbrp10le, so 3, 4, 5, 8
Not sure how to handle that

[nkrabben]

ended up changing the final output format to yuv, which fixed the issue ab26a55

Greetings, Im very grateful for your project, mean ffmpeg art school and all this scripts. This scripts make life easier:) But Im having trouble with the rainbow trail script. I just activated it, but nothing changes in the video. Im the beginner and poorly understand ffmpeg. Maybe I just doing something wrong. I did so: rainbow-trail.ps1 -s /video_files/video.mp blue 0.3 0.1 7 $true. But nothing changes. Please help me. Can you write a couple of examples of what to write down in powershell? Please. I would be very grateful to you. Im sorry and dont know much about computers:) My level is a common user. But i want to get into ffmpeg
Thanks
