Got a encoder error on my first attempt. Here is the information from my original FLV video that I want to break in two so that the file sizes are both under 4GB (for putting on a Flash Drive):
=====================================================
Video
=====================================================
Codec 4CC: H264
Image Size: 1920 x 1080
Aspect Ratio: 1:1 (1:1)

=====================================================
Extra Video Properties

Any suggestions?
As you provide neither the error you mention nor the name of the selected muxer, I can only iterate the steps how it is supposed to work in a current Avidemux build (anything older than 2.7.6 is unsupported, using the latest nightly rather than release is always preferred).
- Load the source video in Avidemux
- Ensure that "Copy" is selected both for video and audio
- Choose "MP4" as output format ( = muxer)
- Identify using the navigation slider, up/down arrow keys or mouse wheel a keyframe suitable for the start of the second half (I assume the total size is below 8 GiB, else you would need either to re-encode with stronger compression or split the video in three parts)
- Set the A marker (with alternative keyboard shortcuts enabled, press "I")
- Save the second half
- Press "Delete"
- Save the first half
Done.
Great Solution! Works great! Many thanks!
