In Use ffmpeg for JPEG to TIFF conversion there is an answer how to convert to TIFF.

So, I followed that process written on that answer:

ffmpeg -i input.avi -pix_fmt rgb24 output.tiff

Though the TIFF file converted then became lossless compressed TIFF files.

How can I convert it to uncompressed TIFF files?

Example

The option you need is -compression_algo with a value of raw or 1:

ffmpeg -i input -compression_algo raw -pix_fmt rgb24 output.tiff

As for the reason for the -pix_fmt rgb24 option see answer to Use ffmpeg for JPEG to TIFF conversion.

Private options

You can view information and options specific to each encoder (also called "private options"):

$ ffmpeg -v error -h encoder=tiff
