Video Encoding - Profile Advanced Options

Could you share a little more information on the video encoding parameters. If I select an Intelligent recode, the video encoding parameters under advanced options are not visible. I assume that means that some of the parameters are being picked up for use from the original video file. Can you share which parameters are being picked up? If I choose force recode those parameters become visible though grayed out until I select an item. Some of the options appear to default to less demanding compression and only two include some minimal level guidance. Does that mean that is what will be used unless otherwise determined from the video file or the user selects a different value?

I have recently been looking more closely at encoding parameters using OBS so this came to mind for VRD.

Thanks

The level and profile are determined by the output settings -- resolution, bitrate, frame rate. They don't determine a thing; more like a "note to the decoder."

All look fine. The danger in changing stuff you don't understand is throwing other parameters out of specification. It's the default because it's what works the best. That said, film tune, one of only two true user options up there, can be a little slow.

The information you are looking for is all here.

It would take years to try to explain it individually in a public forum. Good Luck.

Yes the word "Profile" has different meanings on different planes. Thanks for sharing your VideoRedo Profile.

On the Encoder plane, a Profile is a very specific Metadata statement that drives the codec to recognize the complexity of the encoding parameters..
Encoder Profiles are designated as Baseline, Main, High, ... etc. For instance, at the most basic level, if you specify Baseline, it will not recognize CABAC, an important compression feature. Once again, it is a statement that tells the codec that certain encoding feature sets may or may not be included in the actual file. Hope that makes sense.
