I am using Manycam 7.0.62 on a Dell G3 laptop with 8Gb Ram. While recording videos using chroma-key and up to two PIPs with no other effects, the video freezes in the recording (unnoticeable while recording, but painfully obvious in playback) while the audio continues. I have attempted changing video encoders between Nvidia and Intel, with no improved results. How can this problem be fixed. I need continuous video and audio synchronization while I am creating teaching videos for use online.
