Panasonic GH5 6K Photos: convert to ProRes using FFMPEG

Created a Makefile for using FFMPEG to convert Panasonic H.265 (mp42hvc1 hevc) 6KPhoto files into ProRes files easily processed by current versions of Adobe Premiere Pro.

FFMPEG=~/Downloads/RMMC-0.2.02.0-osx64-en/ffmpeg

SIXKPHOTOS=$(wildcard *.MP4)

TARGET_LIST=$(patsubst %.MP4,converted_%.avi,$(SIXKPHOTOS))
.PHONY: all
all: $(TARGET_LIST)
converted_%.avi: %.MP4

        @$(FFMPEG) -i $^ -c:v prores -profile:v 3 $@
