If it's encoded properly then that's not a problem. The progressive parts will be detected as progressive, and interlaced as interlaced. It's only a problem if it's not done properly.

But it's not mixed.

LAV Mixing Questions

Hi, so I am trying to use the LAV Audio mixer to mix down 6.1/7.1 audio to 5.1, preferably without losing audio information and just dropping channels. What do I need to set the center mix, surround mix, and LFE mix levels sliders to, and what exactly do these settings do? Can I ensure that all of the information in the 6.1/7.1 is folded down into the 5.1?
Also this may be a long shot here but for the ffdshow audio mixer, if I take 5.1 audio and mix down to 2.0, are all the channels in the 5.1 mix carried over to the 2.0 mix, including the LFE channel?

The purpose of mixing is to "fold" all the audio channels into the ones to be output, so they won't be lost.

The channel levels settings do what is explained in the LAV GUI: they control the level of individual channels when downmixing. For example if you downmix to stereo and set one of the settings to 0, you won't hear that/those channel(s).

I suggest to test with this file: https://www.sendspace.com/file/ftt56e
