Without the cleancut option, mythtranscode gets mythplayer<br>> to perform a seek from the start of the cut to the end. That can lead<br>> to a moment of audio and video being slightly out of sync. Mythtranscode<br>> quickly corrects the sync, but there can be a noticeable hiccup. With<br>> the cleancut option, mythtranscode performs the cutting by seeking to a<br>> point a little before the end of the cut, and then dropping audio and<br>> video until the true end of the cut is reached.<br>> <br>> Paul.<br>> _______________________________________________<br><br>Thanks Paul. Hope you don't mind me asking a few more questions - but I'm not hugely familiar with the workings of ffmpeg. In Handbrake I had presets set to default for deinterlacing and detelecine because as my recordings are OTA TV I don't really know if any particular recording will be interlaced / telecine or not or and apparently the defaults were pretty harmless in the cases that they weren't needed and did a good job in the cases where they were needed.<br><br>Do I need to be looking into deinterlacing / detelecine for ffmpeg or does this fifo method just take all of this into account and "sort it out"?<br><br>I think Handbrake and ffmpeg both use x264 for the actual processing but I couldn't find anywhere that would translate Handbrake settings into equivalent ffmpeg settings.<br></div> </div></body>
