​ ​Trancoding Video Presets

​ ​Video Transcoding

Video Transcoding

Updated 12 days ago ​by Blitline Support

Pricing

Video transcoding is much more intensive than regular image processing. As such we charge

    Duration of output video in minutes * $0.0389

Each video duration is rounded UP to the nearest minute. 

Currently we only support pre-set transcoding options

This means that you can tell us the "src" of the video, and choose one of the pre-set trancoding options, and an s3_destination and we will perform the transcoding and upload it to your destination.

To transcode a video, you must submit a job with a "pre_process" and a "trancode" node with various options. The results will be similar to a regular job result, with a "video" result, instead of an "image" result. Meta data will be included with all results.

For example, submiting a job:

{
  "application_id": "YOUR_APP_ID",
  "src": "https://s3.amazonaws.com/blitdoc/gifs/superbowl.gif",
  "src_type": "pre_process_only",
  "v" : 1.22,
  "postback_url" : "YOUR_POSTBACK_URL",
  "pre_process": [
    {
      "transcode": {
        "preset_id" : "System preset generic 720p",
        "video_identifier" : "toms_video",
        "s3_destination" : {
            "bucket" : "YOUR_BUCKET",
            "key" : "grumpy_squirrel/transcoded_out.mp4"
        }
      }
    }
  ]
}

The "transcode" node must contain a "preset_id" from the list of  Trancoding Video Presets

You can enter the "Description" or the "ID" from the list as the "preset_id"
Currently, only "s3_destination" is supported for output.
