Guidance on Implementing Custom Designs and Background Effects for Videos [closed]
23 septembre 2023, par Joel SmithI am currently developing a web application that allows users to upload videos on the frontend. The primary goal of my project is to enable users to add custom designs to their videos and apply background effects. I'm using Python for the backend to handle video processing.


I'm seeking advice on the appropriate technologies, libraries, or approaches to achieve the following :


- 

- Custom Designs : I want to provide users with the ability to overlay custom graphics or text onto their videos. What Python libraries or tools can I use to achieve this ? Are there any best practices for adding graphics and text to videos dynamically ?
- Background Effects : I need to implement the feature to add background effects to uploaded videos. How can I achieve this, and what are the recommended methods or libraries for background replacement or manipulation ?
- Shadow Effects : Additionally, I want to enhance the visual appeal of the videos by adding shadow effects to elements like text or custom designs. What techniques or tools should I explore to achieve this effect ?
4.Combining Videos : To apply background effects, I need to merge the uploaded video with a background video or image seamlessly. What is the best approach to combine videos and maintain video quality during the process ?








I have already implemented the frontend video upload to the backend and would appreciate any insights, code examples, or recommendations that can help me achieve these features effectively.

Cloaked Archive Wiki
16 mai 2011, par Multimedia Mike — GeneralGoogle’s Chrome browser has made me phenomenally lazy. I don’t even attempt to type proper, complete URLs into the address bar anymore. I just type something vaguely related to the address and let the search engine take over. I saw something weird when I used this method to visit Archive Team’s site :
There’s greater detail when you elect to view more results from the site :
As the administrator of a MediaWiki installation like the one that archiveteam.org runs on, I was a little worried that they might have a spam problem. However, clicking through to any of those out-of-place pages does not indicate anything related to pharmaceuticals. Viewing source also reveals nothing amiss.
I quickly deduced that this is a textbook example of website cloaking. This is when a website reports different content to a search engine than it reports to normal web browsers (humans, presumably). General pseudocode :
C :-
if (web_request.user_agent_string == CRAWLER_USER_AGENT)
-
return cloaked_data ;
-
else
-
return real_data ;
You can verify this for yourself using the
wget
command line utility :<br />
$ wget --quiet --user-agent="<strong>Mozilla/5.0</strong>" \<br />
http://www.archiveteam.org/index.php?title=Geocities -O - | grep \<title\><br />
<title>GeoCities - Archiveteam</title>$ wget —quiet —user-agent="Googlebot/2.1"
http://www.archiveteam.org/index.php?title=Geocities -O - | grep \<title\>
<title>Cheap xanax | Online Drug Store, Big Discounts</title>I guess the little web prank worked because the phaux-pharma stuff got indexed. It makes we wonder if there’s a MediaWiki plugin that does this automatically.
For extra fun, here’s a site called the CloakingDetector which purports to be able to detect whether a page employs cloaking. This is just one humble observer’s opinion, but I don’t think the site works too well :
