    Question about editing an mp4 and its properties

    I have a 200 min mp4 video on my desktop of windows 10,
    It is 3.3,gb in size. I only need 15 min of this video
    for a project I?m editing. I use chimp clip on windows 10 to partion this clip ( 15 min) back to my desktop in .mp4 .
    The size of this newly edited video is 2.3 Gb !
    The math doesn?t sound right. So question is why is the size after editing so large?
    Is there a better editing suite to use cheap??
    Windows 10 Home 64 Intel® Core™ i5-8265U (1.6 GHz base frequency, up to 3.9 GHz, 6 MB cache, 4 cores)
    17.3" diagonal HD+ SVA BrightView WLED-backlit (1600 x 900) 256 GB - 5400 rpm SATA
    Windows 10 //21H1 (OS Build 19044..2251) 64bit //Google Chrome 118.0.5993.89 (Official Build) (64-bit)/ 16GB Memory/ AMD Radeon HD 7700 series Video Card//N68C-GS FX2.00 gigahertz AMD Athlon 64 X2 Dual Core /[/B]

    Here are quite a few reasons the size may not significantly decrease...

    You might want to look at the settings of the program you used to see if they can be adjusted to reduce the final output's size.

    You can try Avidemux. It's free and there's even a portable version.
    https://avidemux.sourceforge.net/
    https://portableapps.com/apps/music_...demux-portable

    To save video clips:
    (Ex. cut the beginning and/or end off a video)

    Open Avidemux
    Click the Open Video button
    Browse to your source video file and click Open

    Drag or use the arrow keys to move the time marker to the START point
    Use the double-arrow buttons to go to the nearest keyframe
    Click the [A button to set the START point

    Drag or use the arrow keys to move the time marker to the END point
    Use the double-arrow buttons to go to the nearest keyframe
    Click the B] button to set the END point

    *Important! Make sure to use the nearest keyframe
    or you'll get an "end point of the cut is not on a keyframe" error

    Under Output Format, choose the file type that matches the source.
    Ex. MP4 Muxer for .mp4 files

    Click the Save button
    Choose a destination folder
    Enter a name for the video (Ex. myvideo)
    Click Save
    Click OK
