Wondershare Filmora, poor quality export

Hello, I'm having a crazy story with Wondershare Filmora, every time I export a video, it gets reduced to more than half of its size!

For example, instead of getting a video that's supposed to be 500MB during the export summary, it only ends up being 200MB once the encoding is finished. Or a 60MB video that turns into just a 14MB video!!

The video is still the correct duration of the original file, that's what I don't understand Oo
So I think there's a huge loss of quality...

If you have any idea why or how this is happening... Thank you so much :)

    Hello, please provide us with the characteristics of your rushes definition and the bitrate (bitrate in kb/s), and if possible, the choice of formats for export (definition codec and bitrate).

    Hello Wmv is a proprietary format of Windows !!!!!!!!!!:!!!!!
    a bit of technique a "rushe " it's the video file you want to work on if you decide to reduce the definition and/or the bitrate you will lighten the file but also the quality
    if you have low definition clips and bitrate, there is no point in encoding them with maximum resolution and bitrate the quality will not change
    the question is often asked about the relationship between the display quality of a video, the duration, and its "weight" as a computer file, three elements must be taken into account: the "bitrate" or "debit":
    it's the amount of data "provided per second to make a file more of these data are numerous (bits) the higher the number, the greater the quality of the video
    The resolution in pixels known by 2 numbers
    for example: 1920x1080 is the number of pixels on a screen, length multiplied by height
    for example, a maximum quality is a good HD file at the beginning of course finalized: in mpeg2 1920x1080 at 30000kb/s (kilobits per second) that makes 1go for 5 minutes
    in 1280x720 at 6000kb/s that makes 350 MB for 5 minutes
    in 720x400 at 4000kb/s that makes 215 MB for 5 minutes approximately etc etc....
    so if you display the first on a 50-inch screen it will be excellent
    if you display the last on the same screen you will see the image pixelated as we say
    and if it’s on a smaller screen like a PC screen it will be very decent

    What is a rushes?

    I export them in WMV and the bitrate is different for each video.
    The resolution is also different for each video...
