I am using AWS Elemental Media Converter to convert mp4 video from s3 bucket to m3u8 format. I have created custom output preset but I cannot see them while creating the job. Where is my custom presets how can i select them?
I figured out on my own. It appears to me that it was some glitch because somehow I cannot see them may be the list did not get refreshed or updated but today the preset list got updated and i can see my custom presets.

So as the title says, I have a couple of files in the VOB/BUP format that I need to convert first to .mp4 (I also have .IFO files and I don't know what that is) and then check for a public url to display them (S3 Bucket) But I don't know which one is the correct service.
I have read about MediaConvert, but I'm not quite sure this is the right service for my need.
Thanks in advance for any tips.
VOB/BUP/IFO files are typically found on a DVD where:
IFO files are an index and hold information about the disc contents
BUP files are backup versions of the IFO files
VOB files hold the video and audio content
AWS Elemental MediaConvert does not support these as an input (1).
To convert these, you can consider leveraging a different tool that is capable, for example FFMPeg.
Here is an example batch script you can reference that does this:
https://gist.github.com/andreasbotsikas/8bad3df5309dd0383f2e2c450b22481c
You can also potentially have this workflow run on AWS by using AWS Lambda to run FFMPeg (2).

Today I tried to use Amazon Interactive Video Service with auto record to an Amazon S3 bucket. The problem is that after live streaming ended I want to get the video recorded in S3. I follow the documentation then I get path/prefix like below:
/ivs/v1/<aws_account_id>/<channel_id>/<year>/<month>/<day>/<hours>/<minutes>/<recording_id>
At the path I can find in response json except
<recording_id>
FYI the recording_id created when I start live streaming, but I cannot get a response. So how can I get the recording id with response JSON to access the path of video recorded in S3?
According to the AWS IVS documentation, you'll have to subscribe to the IVS Record State Change event. (see link)
In the event data, there's a key called recording_s3_key_prefix that will be in the following format:
"recording_s3_key_prefix": "ivs/v1/123456789012/AbCdef1G2hij/2020/6/23/20/12/j8Z9O91ndcVs"
You'll be able to get the full path from there or if you just want the recording_id you may extract it from this key as well.
I’m working with Aws MediaConvert in order to create video-files concatenation.
I'm able for now to create concatenation of n videos in one output mpeg4 file, with or without audio "inside each video input".
What i'm looking to achieve is to create the same but with one single audio track for the whole video that i would import and muting each video inputs audio if there are.
I don't know if MediaConvert allows that (not found my case in Aws MediaConvert Documentation).
I made a small schema representing what i'm trying to achieve :
I figured out i can do that with two jobs, one that will concatenate all my video input and mute their audios if there are. And the second one merging the single audio track in the result of the previous one.
This solution however doesn't feel to be the best one.
Do you know if can achieve what i'm trying to do in one job with Aws MediaConvert and if yes, which settings have I to tweak ?
Many thanks in advance !
Maybe you can have look at this link, especially for the following part
If your audio is in a separate file from your video, choose the External file slider switch element and provide the URI to your audio input file that is stored in Amazon S3 ...
By choosing audio from external file and set proper timestamp offset, maybe you can combine your two jobs to one.
So the basic problem is that I am setting up an Amazon connect instance and have successfully started recording calls too but I want the recording audio file to be stored in the S3 bucket in some format(.mp3, .mp4, etc) other than the default that is provided by Amazon (.wav).
Since .wav is the default format and I am not getting any official documentation regarding the change in any format, Any leads would be welcome.
Rather than downloading the file and converting it to the target format, which I have already done, I need the file to be stored in the S3 in the target format itself(anything other than .wav).
Currently there is no capability to change audio format for Connect call recordings; it's fixed at 8 kHz, 16 bit WAV files. But you could set up a MediaConvert job to automatically convert to any format you'd like.
Alternatively you could have a trigger call a Lambda function to do the same thing. Here's a CloudFormation template that sets that up for you.
In both solutions, you might want to adjust the process a bit to delete the WAV file after conversion, to save on storage costs
I'm using AWS 'Elemental MediaConvert' service to get the HLS format of the uploaded video. We are using this as Video-On-Demand service. Everything works fine. Video that is been uploaded in 's3-input' bucket will taken by lambda service and processed by boto3 elemental mediaconvert client. Out of the video will be stored in 's3-output' bucket. One problem is Portrait videos are appearing in Landscape mode in 's3-output' bucket and also when HLS url is played in mobile/browser.
Make sure you use the latest version of boto3 if you use it at all. Anyways
Add "Rotate": "AUTO" to VideoSelector in inputs. In this case, EMC will try to automatically rotate the video based on metadata if it's available.
These links were really useful for me:

Well... In your place here is what I'd do... I'll go to the last "job"... Go to the "output" section. Then go to the output formats sub-sections... and set the size of the desired output Manually.
I don't think Elemental MediaConvert has presets for vertical video. It's a pretty new (awesome) product.
Good luck!
