Warning codes

AWS Elemental MediaConvert returns warning codes when transcoding jobs run into problems that do not prevent the job from completing. You can use Amazon EventBridge to track the warning codes that the service returns. For more information, see Using EventBridge with AWS Elemental MediaConvert.

This table provides detailed information about the warning codes that MediaConvert returns, including possible causes and solutions.

Warning code	Message	Details
100000	Your job couldn't hop from its original submission queue to its destination queue.	Your job waited in its original submission queue for longer than the wait time that you specified, but it couldn’t move to its new destination queue. Check whether your destination queue still exists. No action is required, but your job may take longer than you expect to complete. You control hop behavior, including Wait minutes and the Destination queue, under the Job management Queue hopping settings. For more information, see HopDestination in the API Reference.
220000	Your input file is truncated.	Your input file is missing data and your output's duration may be shorter than you expect. To troubleshoot, check your input for missing content.
230001	Your input's color metadata is missing or incomplete.	MediaConvert could not follow your input's color space because your input has missing or incomplete color metadata. Color metadata includes color primaries, transfer function, and matrix coefficients. Your output might have missing or inaccurate color metadata which can cause players to inaccurately display the video contents. If you specified Color space conversion in the output Color corrector, note that MediaConvert could not convert the color space and may have written inaccurate color metadata. To resolve, manually specify your input's Color space and set Color space usage to Force. For more information, see ColorSpace in the API Reference.
230002	MediaConvert can't apply audio duration correction to your input.	There is something wrong with the 'stts' time-to-sample table in your input file container's audio track, and MediaConvert can't apply audio duration correction. For more information about audio duration correction, see the API Reference. Check your output for any audio video synchronization issues.
230004	Your input is missing information in its 'mdhd' media header atom.	The 'mdhd' media header atom in your input is incomplete or is missing data. MediaConvert expects the 'mdhd' atom to be 32 bytes or 20 bytes. MediaConvert may not read your input correctly. Check the accuracy and quality of your output, including the total file duration and any language codes.
230005	MediaConvert can't find color sample range metadata in your input.	MediaConvert could not follow your input's color sample range because your input has missing or incomplete color sample range metadata. Your output might have missing or inaccurate color sample range metadata which can cause players to inaccurately display the video contents. If you specified Color space conversion or Sample range conversion in the output Color corrector, note that your output's sample range may be inaccurate. To resolve, manually specify your input's Sample range. For more information, see SampleRange in the API Reference.
230006	MediaConvert can’t decode a portion of your input audio.	There's something wrong with your input's file structure or audio stream. Check your input for corruption or other audio encoding issues. Your output may be missing audio content that MediaConvert could't decode.
230007	Your fragmented MP4 input has MOOF fragments that are out of order.	When your input is a fragmented MP4, each MOOF fragment (Movie Fragment Box) should increment sequentially. If you receive this warning, your input may have a discontinuity.
240000	MediaConvert added at least 100 milliseconds of audio silence to keep audio and video in sync.	Your input audio track has missing, corrupt, or unexpected data. Check your output for any audio video synchronization issues.
240001	MediaConvert dropped at least 100 milliseconds of audio to align audio and video.	Check your output for any audio video synchronization issues.
250001	Your input captions have an unsupported font.	You submitted an input caption with an unsupported font. MediaConvert will use a generic font instead.
250002	Your Dolby CBI input has an unsupported bitrate.	You submitted a Dolby CBI input with an unsupported bitrate. MediaConvert will increase it to a supported bitrate. Check that the application generating your DOLBY CBI input is current and up to date.
250003	MediaConvert can't apply Saliency aware encoding to one or more of your outputs.	MediaConvert only applies Saliency aware encoding to outputs that are 720p or higher in resolution that use Single Pass HQ or Multi Pass HQ Quality tuning levels. Use Saliency aware encoding to improve the perceptual video quality of your output by allocating more encoding bits to the prominent or noticeable parts of your content. You will receive this warning for jobs that specify Saliency aware encoding for outputs lower than 720p in resolution or for Single pass outputs. You may also receive this warning message for jobs that specify Saliency aware encoding within an Automated ABR output, or for jobs that use certain Presets or Templates. This warning message is provided for informational purposes, and no action is required.
270000	MediaConvert received a 503 Slow Down error code from Amazon S3 while writing your output to your destination bucket.	While MediaConvert was writing your output files to your destination bucket, it was throttled by Amazon S3. Your job might stall or take longer than expected to complete. You receive a 503 Slow Down error response when you exceed your request rate limit to Amazon S3. Check for any other applications that are making simultaneous requests and limit them. For more information, see Troubleshooting Amazon S3.
