BuiltInStandardEncoderPreset with custom output file name

Question

I am using a transform to convert a source MP4 file ready for adaptive streaming. I am using the AdaptiveStreaming BuiltInStandardEncoderPreset. This is working well however I'd like to customise the auto-generated output file names. Is this possible?

Answer 1

This can be set using the filenamePattern property on the Formats list of a transform output preset:

This example shows how the property can be used:

Answer 2

I've tried specifying the filenamePattern when using the BuiltInStandardEncoderPreset and it doesn't work.

That example you've referenced uses the StandardEncoderPreset not the BuiltInStandardEncoderPreset. Using the StandardEncoderPreset forces me to define all the output resolutions myself. I just want exactly what BuiltInStandardEncoderPreset.AdaptiveStreaming is doing but with the ability to change the output file.

As a workaround is there some documentation on how to use StandardEncoderPreset to produce the same behavior as uiltInStandardEncoderPreset.AdaptiveStreaming?
