# Video passthrough codec support and job settings requirements
<a name="video-passthrough-feature-restrictions"></a>

The following table shows which combinations of input video codec and output container support video passthrough. 


| Supported input video codec | Supported output container | 
| --- | --- | 
|  AVC (H.264) HEVC (H.265)  | CMAF DASH (Common Media Application Format) | 
|  AVC (H.264) HEVC (H.265)  | CMAF HLS (Common Media Application Format) | 
|  AVC (H.264) HEVC (H.265)  | DASH (Dynamic Adaptive Streaming over HTTP) | 
| No supported input video codecs | F4V (MPEG-4 Flash) | 
|  AVC (H.264) HEVC (H.265)  | HLS (Apple HTTP Live Streaming) | 
|  Apple ProRes AVC (H.264) AVC-Intra DV/DVCPRO HEVC (H.265) JPEG 2000 (J2K) VC-3  | MOV (Apple QuickTime) | 
|  AVC (H.264) HEVC (H.265)  | MP4 (MPEG-4) | 
|  AVC (H.264) HEVC (H.265)  | MPEG-TS (MPEG-2 Transport Stream) | 
| No supported input video codecs | MSS (Microsoft Smooth Streaming | 
|  Apple ProRes AVC-Intra DV/DVCPRO JPEG 2000 (J2K) VC-3  | MXF (Material Exchange Format) | 
| No supported input video codecs |  WebM  | 
| No supported input video codecs | Y4M | 
|  AVC (H.264)  |  No container  | 

Additionally, jobs you create with video passthrough have the following requirements.

**Inputs**  
If you specify multiple inputs, each of your input's encoding attributes must exactly match, including video codec, frame size, profile, frame rate, and color space.

**Input clips**  
(Optional) MediaConvert supports input clipping for I-frame only video codecs when you use video passthrough. These include Apple ProRes, AVC-Intra, DV/DVCPRO, JPEG 2000 (J2K), and VC-3.

**Output container**  
When you create MXF outputs from I-frame only inputs, MediaConvert supports the following input frame rates: 23.976, 24, 25, 29.97, 50, 59.94, 60

**Frame rate**  
You must keep the default setting, **Follow source**. You cannot specify a different output frame rate than your input. 

**Audio codec**  
(Optional) MediaConvert supports audio encoding when you use video passthrough. 

**Dolby Digital passthrough**  
(Optional) MediaConvert supports **Dolby Digital passthrough** when you use video passthrough.   
If you specify multiple inputs, each of your input's Dolby Digital streams must have identical encoding attributes. 

**Captions**  
(Optional) MediaConvert supports sidecar formats when you use video passthrough.
