Eos 600d video won't zoom out

[Noor456]

I'm a beginner and don't really know how to use it properly . Recently , I clicked the video mode to check it out . I zoomed in to get more details and now I won't zoom it . The screen show to click display + zoom out button simultaneously but even though I'm doing it it won't work ( but when I zoom in it will work but won't come back to normal )

Can You Have A Video Or A Photo For More Details

I think what you are up against is the fact that DSLRs do not use a powered zoom lens, like a dedicated video camera or a fixed lens digital still camera does. The zoom buttons you are seeing are used to zoom in or out of images on the LCD screen that you've already taken. In some instances they are also used to assist with manual focusing when shooting in Live View mode. Assuming you have a zoom lens mounted to the body, any zooming in or out means turning the zoom ring on the lens by hand.

Hi and welcome to the forum:
The issue you face is that  a dedicated camera is far more complex to operate than, say, a cell phone.  It will require study and it's a journey, but you can achieve much more control that a cell phone can offer.  You need to learn how a camera assesses exposure and how to correctly record that.  This involves the 'holy trinity' of controls: Shutter speed, ISO and Aperture.  May combinations of those will get the correct exposure, but how they are combined will have a major impact on the resultant image in terms of composition.   To get going, I suggest you put the MODE dial in Auto and let the camera make most of the decisions for you.  You will eventually want more control and then move the mode to Av (Aperture control) or Tv (Shutter speed control).   I realize you want to shoot video, but the controls are common, so you're not wasting your time.

By your own admission you "don't really know how to use it properly".  We need to address that or you will live in a world of frustration.
It may seem tedious, but the user guide is your best friend, especially for a beginner.  That is the place you look for features, how-to info etc.  You can download a PDF from this link: eosrt3i-eos600d-im2-c-en.pdf (c-wss.com)
Another source of useful information is one of these videos:

For a general introduction to photography (this is the basis for later learning video), watch the following:

One fantastic resource that will cover all you ever need may be available via your local library.  If you log onto your library website, and search for an item in the catalogue for 'LinkedIn Learning' (it may be called Lynda.com).  It is a linked access to a website that has an amazing array of training, available via your library, free of charge.
You follow the prompts in your library catalogue to open up the site and it will ask you for your library card and pin or password.  This gives you free access.

Once on the site you can search for Photography to find the whole range of videos on the subject but I suggest two places to consider:
1  - to learn to use a Canon Camera, look for "Learning Your Canon DSLR Camera".  This is a 2.5 hour overview of the controls of a DSLR.
2. - For a general series of courses look for "Photography Foundations" where you will find a list of great images on the principles and application of photography.  There are also courses on video.

As to your specific question:
So, my first question would be what lens are you using? If you look at the very front of the lens, it may something like EF-S 18-55mm  or EF (of EF-S) 50mm.  The first one is a multi focal length lens, so it can be zoomed, whereas the one with the single number (50mm), cannot.
