Multiple Questions/Requests

Hello. I know I have a lot of questions but I’ve chosen Shotstack to build a very promising startup. In order for it to get as many users as possible I need to fix a few things, which can be resolved by getting help/answers to these questions

• How can I generate videos in the proper folder associated to a client id (how to pass client-id as part of the folder name) in AWS S3?

• How do I return the AWS S3 URL of the video in the callback when the video is ready?

• How to automatically generate text-to-speech audio for each video based on the provided text using Eleven labs?

• How to automatically adapt text box dimensions based on font size & how to rotate ?

• Do uou have the famous tiktok voice as part of their text-to-speech service: the very first voice that you get when going to this URL: https://tiktoktts.com/

• How much would it cost to add audio to an already-generated video? I want to override the generated videos with the same videos but with an audio chosen from a dropdown added to them.

This one slipped through the net so apologies for not answering this one sooner. In case you are still trying to work these issues out here are some answers:

@benjaminelkrieff

• How can I generate videos in the proper folder associated to a client id (how to pass client-id as part of the folder name) in AWS S3?

  • You should be able to do this using the S3 destination and the prefix setting. Documentation is here with the parameters: S3 Destination | Shotstack Documentation. You can set prefix to client-id and then in your application ensure that the customer with that id can only access files with that prefix. Prefix just looks like a folder in S3.

• How do I return the AWS S3 URL of the video in the callback when the video is ready?

  • To fetch the S3 URL you would need to look it up using the Serve API. When you receibve the callback from Shotstack, that should include the render ID. You can then use the render ID to look up the file in the Serve API and that will return the S3 URL. More details inthe docs here: Manage Hosted Assets withe the Serve API | Shotstack Documentation

• How to automatically generate text-to-speech audio for each video based on the provided text using Eleven labs?

  • To use the Elevenlabs integration, you first need an account with Elevenlabs. You then need to enter your Elevenlabs API credentials via the Shotstack dashboard here: Shotstack Dashboard. That page also includes details on how to call the API to generate the mp3 file.

• How to automatically adapt text box dimensions based on font size & how to rotate ?

  • Right now you would need to set the font size yourself, one way would be to count how many m characters and translate that to a font size that will fit that many m characters. There is a rotate transformation option in the Edit API here: Shotstack v1 API Reference Documentation. It is a clip property.

• Do uou have the famous tiktok voice as part of their text-to-speech service: the very first voice that you get when going to this URL: https://tiktoktts.com/

  • We don’t have this.

• How much would it cost to add audio to an already-generated video? I want to override the generated videos with the same videos but with an audio chosen from a dropdown added to them.

  • The pricing is always the same regardless of how the video is generated, you pay a subscription which gives you upwards of 500 credits. 500 credits will let you create 500 minutes of 720p video. If you render a 1 minute video with no audio and then render the same video but with audio, that is a total of 2 minutes so you would use 2 credits. Ideally you would include the audio and the video in one render, which would just use 1 credit if the length was 1 minute.
