How can I reencode a video to match another's codec exactly?

Question

When I'm on vacation, I usually use our camcorder to record videos. Since they're all the same format, I can use ffmpeg to concat them into one large, smooth video without re-encoding.

However, sometimes I will use a phone or other camera to record a video (if the camcorder ran out of space/battery or was left at a hotel).

I'd like to determine the codec, framerate, etc used by my camcorder and use those parameters to convert the phone vidoes into the same format. That way, I will be able to concatonate all the videos without re-encoding the camcorder videos.

Using ffprobe, I found my camcorder has this encoding:

  Input #0, mpegts, from 'camcorderfile.MTS':
  Duration: 00:00:09.54, start: 1.936367, bitrate: 24761 kb/s
  Program 1 
    Stream #0:0[0x1011]: Video: h264 (High) (HDPR / 0x52504448), yuv420p(progressive), 1920x1080 [SAR 1:1 DAR 16:9], 59.94 fps, 59.94 tbr, 90k tbn, 119.88 tbc
    Stream #0:1[0x1100]: Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz, stereo, fltp, 256 kb/s
    Stream #0:2[0x1200]: Subtitle: hdmv_pgs_subtitle ([144][0][0][0] / 0x0090), 1920x1080

The phone (iPhone 5s) encoding is:

  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'mov.MOV':

I'm presuming that ffmpeg will automatically take any acceptable video format, and that I only need to figure out the output settings. I think I need to use -s 1920x1080 and -pix_fmt yuv420p for the output, but what other flags do I need in order to make the phone video into the same encoding as the camcorder video?

Can I get some pointers as to how I can translate the ffprobe output into the flags I need to give to ffmpeg?

Edit: Added the entire Input #0 for both media files.

Ffmpeg has a filter to use with concat that looks something like this (copied from https://trac.ffmpeg.org/wiki/Concatenate):

ffmpeg -i input1.mp4 -i input2.webm -i input3.mov \
-filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0][2:v:0][2:a:0]concat=n=3:v=1:a=1[outv][outa]" \
-map "[outv]" -map "[outa]" output.mkv

The site linked explains how it all works. With this feature, you don't have to worry about the bitrate. The program adjusts it automatically. Older versions of ffmpeg had some trouble with matching bitrates, but I recently used it for concatenating a video and an animation and it worked fine. Not sure it it will work for frame rate though.
