How do I combine videos?

How can I combine short, iphone videos into one video for a home movie?


I have a bunch of move videos from my iphone from the first year of my son and I would like to make a home video and combine all of them. There is a lot of them. Please let me know the fastest and easiest way to do this on a mac!

MacBook Pro, OS X Yosemite (10.10.5)

With the current QT, you can open the first file, then select all files you want to add and drag them to the window. You have to export from there, so there will be compression. At 1080p, still looks great.


QT7 will stitch together videos and re-save the combined file. You can open the first file. Then move on: open, copy, and paste each subsequent file onto the first. When you're finished, reserve the first file you've added everything too. You'll note it quickly saves instead of recompressing.


I'm not as familiar with the details Jon is discussing. I know that a QT7 file can list multiple tracks. However, using the method I described above, I ended up with ONE video track (copied and pasted over 5 additional files). It opened in Quicktime Pro (X) with no problem.

I tried using iMovie for joining two clips. It reduced the quality and removed the 60fps. I need a real option. Just needs to combine the two without additional compression.

You can use most "classic" QT-based apps like QT 7 PRO, MPEG Streamclip, etc. to store multiple (up to 99) tracks of data in its original compression format, frame rate, and data rate to a standalone or reference MOV file. However, be advised that this workflow normally stores video data to multiple track/layer combinations which modern players and/or online services may not play/handle properly. (I.e., most modern players want all video data "flattened" to a single track/layer for correct playback, transcoding, and/or other processes.) If you are not sharing your results to the general public, then this issue should not be a problem for you. However, if you are sharing the content to others knot to be using modern multimedia players and/or posting the content online, then it is safest to use a workflow that produces a transcoded end result but allows you to manually control the export settings to maintain your 60fps frame rate, as well as, your video resolution/visual quality. Using an intermediate editing compression format may or may not help here.
