LectureTube Editor
Overview
Edit LectureTube videos via TUWEL
Open the video overview

- Click on the "More" tab and select the entry “LectureTube” to display the overview page of your videos (Figure 1).

Edit the video with the LectureTube Editor
Click the “Actions menu” gear icon next to the videos you want to edit and select the option “Video editor” (Figure 2).
The LectureTube Editor allows you to trim your videos that are e.g. uploaded or recorded in a lecture hall equipped with LectureTube. Videos that need to be cut with the LectureTube Editor are marked with the scissor icon “Needs cutting”.
Figure 2: Open the video editor through the gear icon
You will be redirected to the LectureTube Editor. With the LectureTube Editor, you can set cutting marks that will be cut out during the processing of the video on the server. To ensure that the video is trimmed to the actual length of the lecture after successful processing, it is recommended that you set cutting marks at the front and back of the video and mark these segments for deletion. Furthermore, you can mark any segments from the middle of the video for deletion. These can be segments in which no content was presented, or which you do not want to publish.
Use the “Cut“ button to set any cuts in the video track. Then, select a segment and click on “Delete” to mark it for deletion. Segments that will be deleted from the processed video are marked in red colour on the timeline. With “Restore“ you can restore a segment that was marked for deletion before. The “Merge Left” or “Merge Right” buttons allow you to remove the cuts again by merging the current segment with the segment on the left or right side of it. If “Preview Mode” is activated, you will be shown a preview, without the segments marked for deletion (= withour the segments marked in red colour on the timeline), while you play the video.

Edit metadata of the video
In the left menu under “Metadata”, you can edit the data of the video, such as the title of the video or the names of the presenters (Figure 4). Note that not all the data listed is visible to the users.

Delete Video Track
In the left-hand menu under "Tracks", you can delete the track of the camera or beamer from the video afterwards. If this is desired, click on the "Delete track" button for the corresponding track that you do not want to publish (Figure 5).
Please note that this is only possible for recordings made in dual recording lecture halls - i.e. in lecture halls that record a separate video track for the camera and projector. An overview of lecture halls that support dual recording can be found in the room information section of TU coLAB.

Generate Thumbnail
In the left-hand menu under "Thumbnail" you can generate or upload a preview for the video, which will be displayed as a video teaser in the LectureTube series (Figure 6). To generate a preview image from the video, click on the position in the video timeline from which you would like to take the thumbnail. Then generate it by using the "Generate" button. Alternatively, you can use the "Upload" button to select your own image as a video teaser.

Process video with the changes made
Once you have made the desired changes, click on the "Finish" tab in the left-hand menu of the LectureTube Editor.
With the "Start processing" button, you can process the video with the changes you have made (Figure 7).
If you want to save your changes in order to continue editing the video at a later time, click on the "Save changes" button. If, on the other hand, you would like to discard the changes you have made, click on the "Discard changes" button.
If you want to save your changes to continue editing the video at a later time, click on the "Save changes" button. If, on the other hand, you would like to discard the changes you have made, click on the "Discard changes" button.

Confirm your selection again using the "Start processing" button (Figure 8).
Figure 8: Confirm the video processing
Once the changes have been successfully saved, a success message is displayed (Figure 9).
The video is then automatically processed. In the meantime, you can already close the page.

Once the video has been successfully processed, it will be published according to the visibility of the series and will be available for you in your LectureTube series. You only need to integrate your series once, e.g. in your TUWEL course, to make the videos available (Figure 10).
Figure 10: Series integrated in TUWEL
You can integrate both individual videos and the entire series, e.g. in your TUWEL course.
When required, you can adjust the visibility setting of the series via TISS.
You can view the current status of your videos in the video overview in TUWEL.
