Then on the left, select Batch Conversion and Rename, select jpg as the Output Format and check the
box for using the Advanced functions. Click the Advanced button and select the various filters you
want to apply, such as crop, resize, etc. (To get the parameters for crop and resize you might want to
play with an individual frame first before entering Batch mode.) After saving and exiting the Advanced
settings, set the naming pattern and use hash marks for digits. (Be careful about using “-”s in the file
names. Irfanview is a little restrictive on file names.) Use the Options button to choose the starting
number, etc. for the output sequence. Select the output directory and start the batch processing. Be
sure to use non-destructive processing, especially the first few times when you're learning the ropes.
