## Settings
|
|
|
|
You can access the settings by clicking on the settings button in the main interface.
|
|
|
|
|
|
The settings Window is divided into two main parts :
|
|
|
|
- the __basic settings__, where you can change the name of the output file and its location
|
|
- the __advanced settings__, where you can change the behaviour of the algorithm itself
|
|
|
|
|
|
### Basic Settings
|
|
|
|
This is the default page opened when you click on settings.
|
|
|
|

|
|
<p><img alt="Main interface" src="../theme/images/blog/s1.png" /></p>
|
|
</center>
|
|
|
|
|
|
The basic settings page contains only elements:
|
|
|
|
- The output location chooser, where you can change where the timelapse will be saved
|
|
- The name chooser, where you can change the name of your timelapse.
|
|
|
|
|
|
### Advanced Settings
|
|
|
|
|
|
The advanced settings page contain several option you can adjust to modify the timelapse creation algorithm behavior.

|
|
|
|
|
|
### Speed of the video
|
|
|
|
With the speed option, you can select the __framerate of the generated timelapse__.
|
|
The slower you choose, the more delay is added between each frame.
|
|
|
|
Basically, the accessible framerates with the speed option are 3, 6 and 9 frames per second.
|
|
|
|
### Processing mode
|
|
|
|
The processing mode in Ivolution defines the type of video output you desire.
|
|
There are two main processing types : __conservative__, and __crop__.
|
|
|
|
To understand the difference between those two types, you have to know the way Ivolution handles images.
|
|
To create a nice timelapse, each image is resized so that __the faces always keeps the same scale__ during the whole video.
|
|
Each image is also moved so that __the faces always stays in the same place__, even if they are in a different part of the image.
|
|
|
|
You can easily understand this concept by looking at the difference between each mode in this video :
|
|
|
|

|
|
<iframe width="420" height="315" src="http://www.youtube.com/embed/dXuGMZk9_U8" frameborder="0" allowfullscreen></iframe>
|
|
</center>
|
|
|
|
|
|
By choosing the __conservative mode__, all of your images are entirely used.
|
|
This means that none of the images are cropped, and that black borders are added to keep the same dimension over all the video.
|
|
|
|
On the opposite, you can choose the __crop mode__ if you don't want any black border in the video.
|
|
In this case, the images are cropped to fill the maximum space available.
|
|
This gives nicer results, as the video does not contain black borders, but keep in mind the the resolution of the video is also reduced in this case.
|
|
|
|
### Face Type
|
|
|
|
The face type defines the type of video you want to have in output.
|
|
Basically, there are two main different types : __profile faces__ and __front faces__.
|
|
|
|
- __Profile face mode__ expects your images to contain profile faces. Examples of use can be pregnant women that want to see their belly over time.
|
|
- __Front face mode__ is the most common mode, perfect if you take front pictures of you. All of the examples you can see on this website use front configuration.
|
|
|
|
### Sort method
|
|
|
|
The sort method defines __the way images are sorted__ in the video.
|
|
The default mode is __filename__, in which images will be sorted in name order.
|
|
This mode is perfect for most images coming from cameras and webcams, as the file name contains the date at which the image was taken.
|
|
Using this mode, you can also choose to sort the files in the order you want (by naming them yourselves numerically).
|
|
|
|
The other possible mode uses the __EXIF metadata__ embedded in the picture.
|
|
The EXIF metadata contain a special location for the creation date, and Ivolution can use it to sort pictures chronologically.
|
|
Be careful though, because pictures may not contain metadata.
|
|
|
|
If you are not sure, simply leave the default option. |
