    OK so I'll set the scenario.

    We have a camera we attach to our race-car to record races; it automatically records to an AVI format to an SD card.

    I can transfer this to my 2011 MacBook Air no problem, it plays in QuickTime, MPlayerX and VLC.

    But - I have no idea how to go about editing it.

    I've tried iMovie; but it apparently doesn't recognise the AVI; SmartVideo Convertor also doesn't transform the format into something iMovie can read.

    So, what piece of software will let me edit the video? Preferably something cheap/free! All I want to do is cut bits out at the beginning and end, so I can split into single laps or a video easily uploadable to YouTube. Right now the files are about 1.5GB...

    Thanks in advance for any help you can offer.

    I think I used handbrake for this in the past.

    You can do this easily with Quicktime X. Select Edit > Trim or press cmd-T.
