Join two h.264 movie files, merging chapters?
Solution 1
Do you have QuickTime Pro?
It's possible to copy and paste H.264 timelines and merge them together with requiring a re-encode.
Solution 2
I can suggest converting these to mpeg1 first and using a simple concatenate:
cat vid1.mpeg vid2.mpeg > combined.mpeg
More details in: ffmpeg faq. Handbrake uses ffmpeg.
Solution 3
I made a list of various joining utilities. https://spreadsheets.google.com/ccc?key=0AjWmZ0umsuZHdHNzZVhuMTkxTHdYbUdCQzF3cE51Snc&hl=en in general Enjoy!
Solution 4
This is the script I use to join my iPhone movies into ONE iPhone movie.
!#bin/bash
SOURCE_DIR=/mnt/media/images/iPhone
for f in `find $SOURCE_DIR -iname '*.mov' | sort`; do
clip_name=`basename $f .MOV`.dv
ffmpeg -i $f -y -target pal-dvd -s 1280x720 $clip_name
done;
cat *.dv > out.mov
HandBrakeCLI -i out.mov -o out.m4v --preset="iPhone 4" --quality=30

I have two h.264 encoded .m4v files, generated with Handbrake 0.9.3. They used the same Handbrake preset. How can I merge the two files into one movie, and do I need to do anything special to preserve chapter marks?
In case anyone is wondering, they are "An Evening with Kevin Smith", discs 1 and 2. I also own an older copy of "Se7en" which has the movie split between two sides, so I'll run into this issue eventually when I rip/encode that movie.

Jordan almost 15 yearsI would personally just do everything with ffmpeg. Re-encoding a file multiple times will absolutely degrade the quality. If it was pretty high quality at the start, and you're using 'good' settings I would doubt you will see a big difference though. You need to have a pretty trained eye :)
