After I upload a video I try to create a video object by making a POST request to accounts/:account_id/videos. A few days ago, when making this request imediately after uploading the video successfully, I was receiving the error “Media is transcoding.”, but now I am receiving the error “Media failed to transcode.” which means that the transcoding process ended and it failed, and I don’t know why.
The videos with which I tried can be downloaded from here. All 3 videos work with no error if uploaded from the Twitter Ads UI.
I should mention that I am using the ‘media_category’ with the value ‘amplify_video’ in the INIT phase when uploading. A few days ago, when I wasn’t using this parameter, the video would successfully upload and then I was able to create the video object immediately without any errors, so all 3 videos are ok, i.e. they meet all the requirements.
Some video media ids that gave an error are
