Long story short: I use a PC. I want to use a Mac. The videos I want to edit are from a Happauge PVR and are recordings from video game footage on an Xbox 360. It allows me to save my recordings in either .TS, .M2TS, or .MP4. I went to the Mac store and tested the .TS and MP4 on a mpb retina, iMac, and mac mini. The only files iMovie could even recognize was the .mp4. On all the machines it estimated 2-5 hours to import the video file from the desk top into iMovie. The size of the files I need to edit are around 3.40 to 5 GB. Why is it taking so long on the Mac? Is there any way to make it so it doesn't take forever to load such a file in a video editing software? My six year old laptop (Intel Core 2 CPU 1.66 GHz with 2 GB of memory) can load the video into Windows Movie Maker instantly. How is it possible that the Mac is struggling with this? *I understand that FCP allows me to edit the file while it imports it, but we tried this and it still took WAY to long to import it. *I have not tried handbrake to try to find a better file for iMovie to accept, but would this really solve my issue? It would probably take forever as well. Thanks for any advice.
