tips for dealing with synchronization errors

by arigolan » Thu Oct 16, 2014 9:49 am

Even though I have a loud clap a few seconds after the start of the clips, and Autopano says that it has successfully found a synch (via audio), the resulting stitch is slightly off. I also tried a quick back and forth rotation of the monopod for the purpose of motion sync, but that didn't seem to do the trick either... any tips would be greatly appreciated.

This was using 6 GoPro Hero 4 Black cameras on a Freedom 360 rig, and the latest demo version of Autopano Video Pro.

I have found Kolor's audio sync abilities to be very weak. I now have to do it manually in after effects. Motion sync was better. I had some success by firing a strong camera flash and using that as visual sync in Kolor but it only really works well indoors.

I was having issues with some videos as well, one of the GoPros wasn't recording audio and I the motion sync wasn't working so I ended up bringing all video clips into Final Cut Pro X and syncing them there then exporting them individually. It worked perfectly and was fairly easy to do.

Any application that can display the audio wave form of the clip can be used. Identify the peak of the clap sound and record its frame number. Do this for all clips and manually calculate the offsets. You can type these into kolor

Hi!

We have made some improvements on the audio synchronization in AVP 2.0, it's even better now!

Even if the synchronization is at is best but you still have desynchronization (under frame resync / rolling shutter) you can try to use a smooth output (Diamond and no cutting). This generally give more acceptable results.

Cheers,

Martin
