[FFmpeg-user] create video from dng images results in smaller resolution

[Alejandro]

Hi,Im trying to make a video from tiff images that are dng pictures.The problem is that the resulting video that ffmpeg creates, have a resolution slower than the original pictures
I tried with image2 but no luck.
This is from a set of CinemaDNG images. I converted to dng with adobe dng converter. Then i need to change the extension to .tif cause ffmpeg said that no video for the original or the converted ones with .dng extension.With the extensions changed to .tif, ffmpeg is able to create a video but the resolution is super small. 
Why ?(Cause the original files are 2K resolution)
How can i accomplish the goal of make a video from cinemadng images ?



Following is the console ouputs of 3 escenarios
A) THIS CREATES A VIDEO OF 236MB BUT BAD & WITH SMALL RESOLUTION
