Uploading and processing a video
This section describes possible issues with uploading and processing video files in Cloud Video and how to solve them.
Video file processing error
Cloud Video cannot properly process a file due to corrupted data in the container, video stream, or audio stream. This may be due to recording failures caused by camera or memory card issues, corruption during copying or transcoding, etc.
Note that the file might still open and play on your PC, as media players can often mask errors, skip corrupted packets, or reconstruct frames using keyframes.
If the file is corrupted, try enabling Automatically process video file errors when uploading the video. The service will attempt to process the file while ignoring corrupted sections. If this does not help, follow the steps below.
How to check the file
Re-upload the file. If the error persists, the file is likely corrupted.
You can check this by opening the file in a third-party media player (e.g., Windows Media Player, QuickTime, VLC, etc.). A corrupted file may exhibit freezing, artifacts, black screens, and other video or audio issues.
Keep in mind that issues can occur anywhere in the file: even a few corrupted frames can render your entire file invalid for processing.
How to fix the file
-
Re-export the file if created in a video editor.
-
If the original file cannot be restored, re-encode it into a recommended format using FFmpeg
, instructing it to skip corrupted segments:ffmpeg -err_detect ignore_err \ -i <input_file> \ -c:v libx264 \ -crf 21 \ -c:a aac \ -b:a 192k \ -map 0 \ <output_file> -
Optionally, trim the corrupted segment if needed and save a new version.
-
Re-upload the repaired file to Cloud Video.
When to contact support
If the file plays without errors after re-encoding but processing in Cloud Video still fails, contact support
