1080i/25 Commercial
on Jul 28, 2016 at 11:52:04 am

I'm publishing a 1080i/25 PAL commercial for a broadcast studio, and am utilizing the "HD 1080i 25" preset from Media Encoder CC.

The studio has given me the following requirements:
1080i/25 (Interlaced at 25 frames per second, with two interlaced fields. 16:9 widescreen.

Will the "Upper First" field order setting give me the interlacing I need in the video?

And finally, will leaving the "aspect ratio" field as square pixels cause any issues, or would I need to use another PAL widescreen setting here?

Thanks for the assistance....
Eric

Upper field first is correct and square pixels are great. Apparently you have the media container specs all set.

Thanks for the help Dave,

One more question on this. The original render that I did out of AE does not have the "field render" setting turned on, will that cause an issue when I run the encoder preset, or will the "upper fields" setting in the preset handle it fine?

Thanks,
Eric

It will make a very big difference if your source video is interlaced. You'll have to check that. If it is interlaced, then I recommend re-rendering, setting the correct field order in the Render Queue's Render settings.


Just so you know, It's easy to create your own sets of Render Settings & Output Modules. It's just as easy to change the defaults for them. If you know you're making a half-dozen files with interlacing in the ProRes 422 codec, for example, just make new templates and select them as the defaults.
