You can trim a video directly from the Show Content Page. This is a virtual, non-destructive trim for playout purposes. The original video file remains intact. When virtually trimmed videos are uploaded to Connect for CloudCast VOD, the streaming files created will be physically trimmed so only the desired portion is viewable in streaming & OTT apps.
There are two ways to trim a video.
1. In the Preview pane. This requires a preview to have been created for the video.
In the preview pane, drag the ends of the green toolbar to select new in and out points for the video.
As you do, you will see the timing changes reflected in the File Information window on the left of the Show Content page.
Click on the time marker’s forward/backward buttons to move the start or end points forward or backward, one second at a time.
2. Offset-Runtime or Start Trim-End Trim
You can also trim a video by editing the Offset and Runtime directly in the File Information fields.
Depending on the schedule settings you chose in Config → Schedule Configuration your TelVue server displays either Offset and Runtime (Duration) or Start Trim and End Trim to determine where file playout should start and stop and how long the playout should be. If this content was imported with trims or an offset and runtime already in the metadata, it is advisable to use them. If needed, you can set a different trim or offset and runtime manually when you schedule the content. Information on calculating the offset and runtime or start trim and end trim is provided below.
- Offset – how far from the beginning of the file you want to start playing, in hours, minutes, and seconds. For example, if the file begins with 3 minutes of announcements prior to a soccer game, enter 00:03:00 to skip the announcements and begin the file when the game begins. To play the file from its beginning, leave this field blank.
- Runtime – the length of time you want the playout to run, in hours, minutes, and seconds. For example, suppose you captured a soccer game for 2 hours (2:00:00). The game ends 1 hour and 55 minutes into the file and you want to skip the 3 minutes of announcements at the beginning. To end each playout when the game ends, enter 1:52:00 for the runtime. To end the playout when the file ends, enter 1:57:00 or click on Calculate Max Duration as described below.
- Calculate Max Duration – This utility subtracts the offset from the untrimmed length of the file to get the runtime without any end trim. Click on the words Calculate Max Duration to use it. If you want the runtime to be less than the max duration, change the entry in the Runtime field after calculating the Max Duration.
- Start Trim – how far from the beginning of the file you want to start playing, in hours, minutes, and seconds. For example, if the file begins with 3 minutes of announcements prior to a soccer game, enter 00:03:00 to skip the announcements and begin the file when the game begins. To play the file from its beginning, leave this field blank.
- End Trim – how far from the beginning of the file you want to stop playing, in hours, minutes, and seconds. For example, suppose you captured a soccer game for 2 hours (2:00:00). The game ends 1 hour and 55 minutes into the file. To end each playout when the game ends, enter 1:55:00 for the end trim. To end the playout when the file ends, enter 2:00:00.
- Virtual Trim – When you use the Start Trim and End Trim fields together the application calculates the trimmed length of the file as:
- Runtime = – – [ – ].
- For example, if you want to trim the soccer game file from both ends, enter 00:03:00 for the start trim and 1:55:00 for the end trim.
Runtime = 2:00:00 – 00:03:00 – [2:00:00 – 1:55:00]
= 2:00:00 – 00:03:00 – 00:05:00
= 1:52:00
