Start with installing the depdencies through pip.

Start by executing:

$ python getnative.py inputFile [--args]

That's it.


To run this script you will need:

Example Output

Input Command:

$ python getnative.py /home/infi/mpv-shot0001.png -k bicubic -b 1/3 -c 1/3

Output Text:

Using imwri as source filter
Kernel: bicubic AR: 1.78 B: 0.33 C: 0.33
Native resolution(s) (best guess): 720p, 987p
done in 29.07s

no-save Do not save files to disk. False Action


This script's success rate is far from perfect. If possible, do multiple tests on different frames from the same source. Bright scenes generally yield the most accurate results. Graphs tend to have multiple notches, so the script's assumed resolution may be incorrect. Also, due to the current implementation of the autoguess, it is not possible for the script to automatically recognize 1080p productions. Use your eyes or anibin if necessary.
