# First we cut the video in how many parts we want

# Step 1. cut the first part of the video and cut it to a separate file
ffmpeg.exe -ss 00:00:00.000 -t 00:02:18.00 -i recording-full.flv -c:v copy -c:a copy recording-full-part1.flv

# Step 2. cut the second part from original video
ffmpeg.exe -ss 00:03:47.000 -i recording-full.flv -c:v copy -c:a copy recording-full-part2.flv

# Step 3. create a file with your cut parts to concat into one video with these contents and name it whatever (i.e. videos.txt):
file 'C:\Path\To\recording-full-part1.flv'

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
