How can I sync the frames of multiple videos from a multi-camera capture system using FFMPEG - bash

Question

I have a multi-camera capture setup with 2 canon cameras. Each of these cameras have a tentacle sync e timecode generator connected to them.
After a video capture with these 2 cameras, the generated timecode (SMPTE format) is stored in the video files metadata.
It looks like this 00:00:53;30
Is there a bash script that uses FFmpeg to trim the start time of the video that started earlier (based on timecode) to match the other and then trim the end time of the video that ended last to match the one that ended first?
The two trimmed output videos should be synced based on the timecode and have the same duration.
So far, my bash script looks like this:
file1="A001C002_220101EB_CANON.MXF"
file2="A001C002_220101US_CANON.MXF"
# Get the SMPTE timecodes of the two files
timecode1=$(ffmpeg -i "$file1" 2>&1 | sed -n 's/timecode.*: \(.*\)/\1/p')
timecode2=$(ffmpeg -i "$file2" 2>&1 | sed -n 's/timecode.*: \(.*\)/\1/p')
# Convert the SMPTE timecode to start time in seconds
start_time_1=$(echo "$timecode1" | awk -F ':' '{print 3600*$1 + 60*$2 + $3}')
start_time_2=$(echo "$timecode2" | awk -F ':' '{print 3600*$1 + 60*$2 + $3}')
# Trim the start of the video with the earlier start timecode so that both videos have the same start time
if [ "$start_time_1" -lt "$start_time_2" ]; then
ffmpeg -i "$file1" -ss "$start_time_2" -c:v libx264 -crf 18 -preset veryfast trimmed_file1.mp4
ffmpeg -i "$file2" -c:v libx264 -crf 18 -preset veryfast trimmed_file2.mp4
else
ffmpeg -i "$file2" -ss "$start_time_1" -c:v libx264 -crf 18 -preset veryfast trimmed_file2.mp4
ffmpeg -i "$file1" -c:v libx264 -crf 18 -preset veryfast trimmed_file1.mp4
fi
# Get the duration of both files
duration_1=$(ffmpeg -i trimmed_file1.mp4 2>&1 | grep "Duration" | cut -d ' ' -f 4 | sed s/,//)
duration_2=$(ffmpeg -i trimmed_file2.mp4 2>&1 | grep "Duration" | cut -d ' ' -f 4 | sed s/,//)
# Convert the duration to seconds
duration_1_secs=$(echo $duration_1 | awk -F: '{ print ($1 * 3600) + ($2 * 60) + $3 }')
duration_2_secs=$(echo $duration_2 | awk -F: '{ print ($1 * 3600) + ($2 * 60) + $3 }')
# Trim the end time of the video that ended last to match the one that ended first
if [ "$duration_1_secs" -gt "$duration_2_secs" ]; then
echo "Trimming end time of file1 to match file2"
ffmpeg -i trimmed_file1.mp4 -t "$duration_2" -c:v libx264 -c:a aac trimmed_file1.mp4
else
echo "Trimming end time of file2 to match file1"
ffmpeg -i trimmed_file2.mp4 -t "$duration_1" -c:v libx264 -c:a aac trimmed_file2.mp4
fi
But this does not make the videos have matching frames.
Thanks!
