In this section we will introduce an example of how video inputs can be modified as part of encoding and packaging with MediaConvert.
Video content often needs to be combined or stitched with other videos. For example, if you have a YouTube channel, you may want to always play a channel clip at the begining of a piece of content and invite viewers to subscribe to the channel or promote other content at the end of each piece of content. These are referred to as bumper videos.
Sometimes you may also want to clip the input videos before you stitch them together. For example, you want to make a sizzle reel that combines multiple clips of larger videos into a single video you can use for promotion.
In this module you'll modify the AWS Elemental MediaConvert job you created in the last module to combine several video inputs into a single video.
You need to have access to MediaConvert and S3 to complete this module.
You need the following resources created in module 1:
- MediaConvertRole - the role created to give permission for MediaConvert to access resources in your account.
- MediaBucket - the bucket created to store outputs from MediaConvert.
- MediaConvert job from module 2 - We will start with this job and modify it in this module.
If you used CloudFormation to configure resources, you will find the values names of MediaConvertRole and MediaBucket in the Outputs of the Stack.
Create duplicate of the job you created in module 2. Modify the job to clip the first minute of the vanlife video and then stitch on a trailing video at the end. The new job will have the following structure:
- Open the MediaConvert console for the region you are completing the lab in (US-West-Oregon). https://us-west-2.console.aws.amazon.com/mediaconvert/home?region=us-west-2#/welcome
- Select Jobs from the side bar menu.
- Find the job you created in the last module and click on the Job Id link to open the Job details page.
- Select Duplicate
-
Select Input 1 from the menu sidebar.
-
Scroll down to the Video selector panel and select Start at 0 from the Timecode source dropdown.
-
Scroll down to the Input clips panel and select Add input clip.
-
Enter
00:00:00:00in the Start timecode box for Input clipping 1 -
Enter
00:00:30:00in the End timecode box for Input clipping 1
-
In the Input section of the MediaConvert side bar menu, select Add.
-
Make sure Input 2 is selected from the Input section of the MediaConvert side bar menu.
-
Enter
s3://rodeolabz-us-west-2/vodconsole/TRAILER.mp4in the box on the Input 2 panel.
- Scroll to the bottom of the page and select Create
- Wait for the job to complete. Monitor the status of the job by refreshing the Job detail page.
To play the videos, you will use the S3 HTTPS resource Link on the videos S3 object Overview page.
The MP4 output is located in your ouput s3 bucket in the object: s3://YOUR-MediaBucket/assets/VANLIFE/MP4/VANLIFE.mp4
You can play the MP4 using:
- Chrome by clicking on the Link for the object.
- JW Player Stream Tester by copying the link for the object and inputing it to the player. https://developer.jwplayer.com/tools/stream-tester/
The HLS manifest file is located in your ouput s3 bucket in the object: s3://YOUR-MediaBucket/assets/VANLIFE/HLS/VANLIFE.m3u8
You can play the HLS using:
- Safari browser by clicking on the Link for the object.
- JW Player Stream Tester - by copying the link for the object and inputing it to the player. https://developer.jwplayer.com/tools/stream-tester/
You should be able to view thumbnail JPEG files using your browser.
The HLS, MP4 and Thumbnail outputs should be modified to play the first 30 seconds of the VANLIFE video, followed by a 21 second clip of aerial footage of some sea stacks.
Congratulations! You have successfully created video conversion job with multiple inputs and outputs for AWS Elemental MediaConvert. Move forward to the next module to add watermarks to your job outputs.
