Re: Fast paning weirdness
Here's a link. I used a 20kHz sinetone and recorded it through a surround panner to a stereo track. The waveforms show the automation steps with different amounts of breakpoints. I did an arbitrary 8 frame region for this snapshot. I hope the image resolution is clear enough.

Now Digi just has to put in an "un-thin automation" function Is there a trick to quickly put in more breakpoints on a given line? Or did you manually pencil them in one by one? Thanks again! Frank.

Re: Fast paning weirdness
I used the grabber. No, it isn't quick, but at least with the grabber you don't have to be super precise, just click somewhere near the line and a point is placed without causing a new bend. I like to get the pan length right and then add the smoothing inbetween points. Usually, though, I don't care enough to bother, mixing mostly tv crud here.
Who is this "Digi" person you speak of? :| |

Re: Fast paning weirdness
So, the lesson to be learned here is to set PT automatic automation thinning to none.
Frank.

The shape of those curves without extra automation breakpoints is very curious, looks like some kind of buggy byproduct of the automation interpolation routines. They are not stairstepped, as I had expected based on what it sounds like. There is obviously some kind of realtime interpolation working, it just isn't doing ideal calculations for a panner and there appears to be unequal "give and take" between channels, which probably contributes to the uneven sound of fast panner moves. It makes me wonder what exactly is happening during other fast parameter moves. Nah, I don't really want to find out. |

Re: Fast paning weirdness
Hi,
just wanted to give AVID a heads-up because this still happens in PT10. Maybe a fix for PT11? Or an "un-thin automation" feature? Had to pan 50 fast car bys today manually putting in breakpoints so they pan smoothly. Probably 200 extra-clicks that could be avoided ;-) Thanks, Frank.
