Using Avidemux to split a video file

December 11, 2016

This blog post is for me, in case I forget how to do these steps! If it helps you, well and good, but it’s part of my brain dump for myself as it’s is only something I’ve done once before and had to relearn it for the second time I needed to use it.

Problem

My Samsung TV is from 2010, so it isn’t a ‘smart’ TV. Occasionally, we watch videos from an external hard drive. However, I think my TV has problems with large files (anything much over 2GB). No matter the format of the files (MP4, MKV, AVI etc.) they won’t even show on the TV as existing, if they’re over ~2GB (I’m not sure what the magic number is but it’s a tad more than 2GB but substantially less than 3GB). I did some Google searches and found that it could be the format of the hard drive — so I tried reformatting a spare hard drive as exFAT, FAT32, and NTFS, as recommended in various forums. Nothing worked. Still the >2GB files wouldn’t show.

What I needed to do was split the video files into smaller chunks, each less than 2Gb in size. Enter Avidemux.

Solution

I used Avidemux because I already had it and had used it once before for something quite some time ago. I had to relearn what to do, so for my future self, here’s how to split a large video file into smaller chunks.

Environment: Windows 7, Avidemux 2.6.8 – 64 bit

  1. Load the file into Avidemux (either drag and drop from the folder or use File > Open).
  2. If displayed, wait a minute or two until the two progress bar screens are finished.
  3. Check the settings on the left side of the Avidemux screen: Video and Audio Output – Copy; Output Format – select the same as the original file (e.g. MP4, MKV)

  4. Use the slider or playback controls to get to the starting point of the new clip.
  5. Click A.
    avidemux02
  6. Use the slider or playback controls to get to the end point of the new clip.
  7. Click B. The new clip is bounded by a blue box in the slider area.

  8. Go to File > Save, then navigate to where you want to save your new clip.
  9. Give it a file name, then click Save. The recording will start and take a few minutes.
  10. When finished, you can either create another clip (as you would if you’re splitting a large file), or close the file. To create another clip, click A again then repeat steps 6 to 9.

  1. Nice tips! I usually use this: http://www.videostudiopro.com/en/pages/split-video/ to split and edit videos, but I could give Avidemux a chance too
