Video Transcoding
Video Transcoding
Pricing
Video transcoding is much more intensive than regular image processing. See our pricing page: https://www.blitline.com/v3/home/pricing_calc
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.
