using ffmpeg to reverse multiple video files

The ffmpeg documentation warns about files being too large:
Warning: This filter requires memory to buffer the entire clip, so trimming is suggested
I have a video on how to break a video up into smaller chunks

Firstly the ffmpeg command to reverse a single file is 0:34 :

ffmpeg -i input.MOV -vf reverse reversed_output.MOV

-i input.MOV is the video that I want to reverse
-vf reverse creates the filtergraph specified by reverse and use it to filter the stream
reversed_output.MOV is the video that has been reversed

I have a bunch of videos numbered consecutively file input_000.MOV, input_001.MOV etc... up to input_012.MOV that I want to reverse. So I make a script 2:41 :

#! /bin/sh

for i in{000..012}
do
ffmpeg -i input_$i.MOV -vf reverse output_$i.MOV
done
