codingdirectional: Create an animated image feature for the video editing application

It seems like there are lots of people reading this video editing project and share this project with their friends which has really encouraged me to continue developing this project. There are a few of you that ask me to include a few new features into this application and I will do that but for now, do allow me to tidy up the user interface for this project first before we proceed further.

In this chapter, we will create the input box which will receive the time duration input which then will be used to extract an animated image from a video. The user will enter the starting time where he wants the program to start recording the animated image and the total second he wants the animated image to play from that starting time. Besides that, I have also included a counter which will be used to name the new video or the animated image file. If you have entered a valid digit inside the time input box under the animated image part of the application then only the animated image with the selected size will be created. Otherwise the new video will be created as usual. Below is the entire program.

Below is the new user interface of the video editing software.

The animated image user interface

Here is the animated image from part of the wild life video.

http://islandstropicalman.tumblr.com/post/182216728822/animated-gif

The gif file created from the video can be very large so be very very careful and try to reduce the duration of the animated image as much as possible.
