You want to create proxies in Premiere Pro- and the existing presets are not suitable for your medi a. How do you create a custom Ingest preset for Premiere Pro?

When the default proxy presets in Premiere Pro are not suitable, a custom encoding preset must be created first. This process is performed in Adobe Media Encoder (AME). In AME, you can define the exact specifications for your proxy files, such as codec (e.g., ProRes Proxy), resolution, and frame rate, and then save these settings as a new encoding preset. This newly created preset then becomes available within Premiere Pro's Ingest Settings dialog, where you can select it to create your final Ingest Preset for the proxy workflow. Therefore, using AME is the foundational step to create a truly custom preset when the defaults are inadequate.

B. The menu path File > Export > Ingest Preset does not exist in Adobe Premiere Pro; this is an incorrect procedure.
C. The preference Save Export Presets as Ingest Presets is not a valid setting in Premiere Pro's preferences panel.
D. While the final Ingest Preset is configured and saved from Premiere Pro's Ingest Settings, this dialog relies on an underlying encoding preset. If the existing encoding presets are unsuitable, as stated in the scenario, the primary creation of the custom settings must happen in Adobe Media Encoder first.

1. Adobe Premiere Pro User Guide, "Create ingest presets with Adobe Media Encoder": "You can create ingest presets in Adobe Media Encoder to use in Premiere Pro. In Adobe Media Encoder, select Preset > Create New Preset. The Preset Settings dialog opens. In the Preset Settings dialog, select the desired format and base preset for your ingest preset... To use the ingest preset in Premiere Pro, see Ingest settings." This source directly states that the creation process for custom presets to be used for ingest starts in Adobe Media Encoder.

2. Adobe Premiere Pro User Guide, "Ingest and Proxy Workflow in Premiere Pro": Under the section "Create an Ingest Preset," the documentation explains the process within Premiere Pro but includes the crucial step: "To create a new encoding preset, click Add Encoding Preset. Adobe Media Encoder launches. Create and save the encoding preset in Adobe Media Encoder." This confirms that for a new, custom encoding, AME is the required tool.
