If i am not mistaken, you cannot do that without any side application install to your phone.
Maybe you can try out this:
1) Copy the link from Twitter (the video link which you want), go to twittervideodownloader.com and paste your link there. Then you can download it directly to your phone.
2) Install an application called 'Tweeload'. Same method as point 1 above. Just that this one is using an application to download the video. The above method is using web browser from your phone.
3) You can also use the Samsung Edge panel function to record the video out. BUT, this method is only to convert the video into GIF file (moving images without voice) only. The file format is images (GIF) instead of MP4 or any other video format.
Have a nice day.
