Accelerated transcoding job settings requirements
Before you enable Accelerated transcoding, make sure that your job conforms to the following requirements and limitations.
Video inputs supported with Accelerated transcoding
The following table shows the video input codecs and containers that MediaConvert supports with Accelerated transcoding.
Container | Video Codecs Supported with Container |
---|---|
HLS (MPEG-2 TS segments) | AVC (H.264), HEVC (H.265) |
IMF | JPEG 2000 (J2K) |
Matroska | AVC (H.264), MPEG-2, MPEG-4 part 2, VC-1 |
MPEG Transport Streams | AVC (H.264), HEVC (H.265), MPEG-2, VC-1 |
MPEG-4 | AVC Intra 50/100, AVC (H.264), HEVC (H.265), MPEG-2 |
MXF | Apple ProRes, AVC Intra 50/100, AVC (H.264), JPEG 2000 (J2K), MPEG-2, SonyXDCam, SonyXDCam (as an MPEG-2 variant only), VC-3 |
QuickTime | Apple ProRes, AVC Intra 50/100, AVC (H.264), JPEG 2000 (J2K), MPEG-2 |
Note
For HLS inputs, your package must conform to the requirements listed in HLS input requirements.
Video outputs supported with Accelerated transcoding
The following table shows the video output codecs and containers that MediaConvert supports with Accelerated transcoding.
Container | Codecs Supported with Container |
---|---|
CMAF | AV1, AVC (H.264), HEVC (H.265) |
DASH | AV1, AVC (H.264), HEVC (H.265) |
HLS | AVC (H.264), HEVC (H.265) |
MPEG-2 TS | AVC (H.264), HEVC (H.265) |
MPEG-4 (.mp4) | AV1, AVC (H.264), HEVC (H.265) |
MPEG-4 Flash (.f4v) | AVC (H.264) |
MXF | AVC (H.264) |
QuickTime | AVC (H.264) |
Smooth (ISMV) | AVC (H.264) |
WebM | VP8, VP9 |
Raw (no container) | AVC (H.264), HEVC (H.265) |
Note
For MPEG-2 TS outputs, to use Accelerated transcoding, you must change the default value of CBR for Transport stream settings > Rate mode to VBR.
Output restrictions
-
Your output must have a video component. MediaConvert doesn't support Accelerated transcoding with audio-only outputs.
-
Use only supported combinations of container and codec. The preceding table shows the supported video output codecs and containers.
-
Use any output audio codec other than Dolby Atmos. MediaConvert doesn't support Accelerated transcoding with Dolby Atmos.
-
Use only supported output captions formats. For Accelerated transcoding, MediaConvert doesn’t support the following output captions formats:
-
Not supported: Burn-in
-
Not supported: SCTE-20
For a list of supported captions formats, see Supported input captions, within video containers.
-
Transcoding features not supported with Accelerated transcoding
-
Avail blanking
-
Motion image inserter
-
Interpolated frame rate conversion
-
VBI passthrough
-
Timecode passthrough
-
SEI timecode
-
Timecode anchor
-
Telecine output
-
Inverse telecine output
-
Embedded timecode source
Note
With Accelerated transcoding, you can set the input setting Timecode source to Embedded, but not the job-wide setting Source under Timecode configuration.
-
Black video generator
-
Pad video
-
Inputs with variable frame rates
-
Inputs with discontinuities
