From this thread,

but I got another problem that can be related with deinterlacing.

In the x264-reencoding video, the audio isnīt synced with the guy talking in the video.

Can this happen because the video is interlaced at the mainvideo, but progressive at the endtitles, but I deinterlace the whole video?

Thanks

Depends on the filter you used. With most filters that shouldn't happen, as they apply the same deinterlacing to the whole video, even to the progressive parts, where it shouldn't be necessary.
Post more details on how you deinterlaced (AviSynth script) and the nature of the desync (progressively worse or constant).

It looks like constant desync. Audio is slightly (~1 second) ahead of the video.

Then it probably doesn't have anything to do with the deinterlacing.

Thanks.
