With KLEKSI you can manage various types of media files. In the DAM/file manager you can upload any type of file you want. You can then describe it as an object. To ensure that data traffic during the use of KLEKSI and to minimize the data traffic of visitors on the frontend, images, audio files and video files are automatically converted to optimized files that load quickly and efficiently. For example, video files are automatically converted to two different bitrates to minimize data traffic and leave the smallest possible ecological footprint.

On the object management page you can manage the media files such as images, audio files and/or video files that you want to describe or add to an object at the top right. By clicking on the + button you can add a new file to the object in question. The file manager/DAM (see: File manager/DAM) opens with all the files that you have already uploaded. Select 1 or more files that you want to add and then click on 'Select file(s)'. The files are then added.


Images
After an image has been added, there are three buttons next to the image. One to edit the image, a button (trash can) to delete the image and a button (horizontal lines) with which the image can be moved (drag and drop) to another position (for multiple images) by dragging it and releasing it at the position where you want the image to be.


Image editing tool
Using the image editing tool you can edit and crop images. Click on 'Edit' for an image that you have added to a description or object, the image editing tool will open. On the left side you see the image with a blue line around it. By dragging this line you can determine which part of the image you want to crop. On the right side you see a preview of the part that you want to crop. You can also rotate an image left or right or flip it horizontally or vertically. After you are done, click on save, a new file is generated from the original file. The original file is saved untouched in the Filemanager/DAM. The image (copy) that is generated from the original file is automatically converted to the smallest possible file without loss of quality. This saves data traffic while managing your descriptions or objects and the visitors of your website do not have to deal with long waiting times.

If you want to adjust the edited image again, the original image is loaded with the blue lines with coordinates of your previous edit. You can then drag the blue line to another position so that you get a new section of the original file. After you have made changes, a new image is generated again from your last edit. In this way, you can generate multiple images of details for a description or object from 1 image.


Audio and/or video files
KLEKSI automatically generates videos in different bitrates, depending on the source file. What is important to know is that we are flexible in this and are not stuck with standard settings. For example, if you want to upload a 100GB video and you notice that the current bitrate is too high or too low, we can always look together for a solution that better suits your needs. This can mean that we create multiple bitrates, or just a single lower bitrate, depending on the situation and the wish.


Types of video files
We strive to support all common formats you want to upload. If you need a specific format that is not yet supported, we can usually add it easily. Only in the case of very special formats (which may have licensing conditions) may we need to coordinate further.

Different bitrates
We have chosen to convert videos to a DASH stream with two quality levels: high and low quality. In addition, a low quality MP4 file is always offered as a fallback, together with a poster.jpg in maximum resolution and a thumbnail.jpg (256x256 pixels). The resolutions we support are as follows:

• High quality (1080p): 6000 kbps
• Low quality (720p): 3000 kbps
• Low quality (480p): 1000 kbps
• Very low quality (360p): 600 kbps
• Very low quality (240p): 300 kbps

These settings can of course be adjusted depending on the specific requirements. The final choice of resolution depends on the original video resolution. For example, if the original video is smaller than 1080p, we choose 720p (30fps), and if it is smaller than 480p, we use 360p or 240p, whichever fits best (24fps).

The file size of course depends on the video itself, such as the duration and the amount of movement in the images (dynamic scenes require more data than static images). 4K videos are also no problem, but keep in mind that this requires more traffic and storage space.

After you have added an audio or video file, there are two buttons next to the preview. One to remove the file and a button (underscores) with which the file can be moved (drag and drop) to another position (for multiple files) by dragging it and releasing it at the position where you want the file to be.
