[FFmpeg-user] 1080i AVC-I 100 frame rate conversion

[Bruce Roberts]

Hi again Carl,

I've done another test and have uploaded both the input and output files
(which shows the luminance bands problem near the bottom of the output
picture) here:
https://drive.google.com/drive/folders/1YTUNHm4_oIZFfGge-JqlDT0c71ioLulY?usp=sharing

Here is my command and the console output:

ffmpeg \
-r 23.976 -i /Volumes/Samsung_T5/bars_23_976.mxf \
-filter_complex \
