I'm 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 lower 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 was found. 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 create a video from these images?
This creates a video of 236MB but bad and with small resolution:
D:/>ffmpeg -f image2 -start_number 00101600 -i D:/temp/dng/conv2/00%3d.tif copy -qscale 1 D:/temp/dng/conv2/temp/11.avi
