# Creating a video encode from scratch
Creating from scratchCodec details for AV1

AV1 output encodes now support a configurable Bit Depth field.Profile, bit depth, chroma sampling

The guide now includes information about the values in the Profile field that you fill in when you create a video output encode.

You can create a video encode by entering values in all the appropriate fields. Follow this procedure for video in all types of outputs except for Frame capture outputs. 

1. On the **Create channel** page, find the output group that you [created](creating-a-channel-step4.md). 

1. Under that output group, find the output where you want to set up a video encode.

1. Choose the link for the video encode.

1. For **Codec settings**, choose the codec to use for this encode. More fields appear in several sections.

1. Complete each field as appropriate. For details about a field, choose the **Info** link next to the field.

## Width and height (resolution)


For information about the **Width** and **Height** fields (which define the video resolution), choose the **Info** link for each field. The frame rate affects the output charges for this channel. For more information about charges, see [the MediaLive price list](https://aws.amazon.com/medialive/pricing/).

## Rate control


For information about the **Rate control** fields, see [Setting the rate control mode](video-encode-ratecontrol.md). There are fields in this section that affect the output charges for this channel. For more information about charges, see [the MediaLive price list](https://aws.amazon.com/medialive/pricing/).

## Framerate


For information about the **Framerate** fields, choose the **Info** link for each field. The frame rate affects the output charges for this channel. For more information about charges, see [the MediaLive price list](https://aws.amazon.com/medialive/pricing/).

## Codec details


### Profile field for H.264


The **Profile** field sets the profile, chroma sampling, and bit depth. 


|  Value in **Profile** field  |  Profile   |  Chroma Sampling   |  Bit Depth   | 
| --- | --- | --- | --- | 
|  **Baseline**   |  Baseline   |  4:2:0   |  8-bit   | 
|  **Main**   |  Main   |  4:2:0   |  8-bit   | 
|  **High**   |  High   |  4:2:0   |  8-bit   | 
|  **High 10bit**   |  High   |  4:2:0   |  10-bit   | 
|  **High 422**   |  High   |  4:2:2   |  8-bit   | 
|  **High 422 10bit**  |  High   |  4:2:2   |  10-bit   | 

### Profile field for H.265


The **Profile** field sets the profile, chroma sampling, and bit depth. 


| Value in Profile field |  Profile   |  Chroma Sampling   |  Bit Depth   | 
| --- | --- | --- | --- | 
| Main |  Main   |  4:2:0   |  8-bit   | 
| Main\$110BIT |  Main   |  4:2:0   |  10-bit   | 

### Bit depth and level fields for AV1


The **Bit Depth** field sets the bit depth for the AV1 output encode. Choose **DEPTH\$18** for 8-bit output or **DEPTH\$110** for 10-bit output. If you don't specify a value, the default is 8-bit.

The **Level** field sets the level. Other encoding schemes (profile, chroma sampling, and tier) are hard-coded. For more information, see [Encoding schemes for the AV1 codec](video-characteristics-encoding-schemes.md#video-characteristics-encoding-schema-av1).

## Timecode


For information about the **Timecode** fields, see [Working with timecodes and timestamps](timecode.md).

## Color space


For information about the **Color space** fields, see [Handling complex color space conversions](color-space.md).

## Additional encoding settings


For information about the **Additional encoding setting**s fields, see [Setting up enhanced VQ mode](video-enhancedvq.md)
