Here's what I've learned so far: Version used: v.8.63 VideoPad (on Windows 8.1, upgrading it to 10 is not an option) - Within VideoPad, before export, the playback works as desired (both time reduction and corrected pitch preview together correctly). - Exporting the video with "keep pitch unchanged" box UNchecked properly exports time aligned video and audio (mp4/720p preset for YouTube tested) but speaker voice sounds like daffy duck (as expected). Unfortunately, I really need both features to work (pitch corrected and 4% reduced time). - Exporting to AVI format with various quality/encodng settings does not resolve the issue - Exporting as MP4 (h264, h265, MPEG using various video and audio settings) does not resolve the issue. Neither does . MOV or .SWF. I tried numerous configuations, at various quality settings, and all experienced audio drift problem. - In another experiment, I converted the original iPAD .mov file to constant 30fs .mp4/h.264 using another tool, then split the audio and video into separate files/tracks using FFMPEG and then re-imported them into Video Pad each as a separate file (not just unlinking them from the original native to VideoPad). Still has a problem on export. - Manual alignment is not an option within VideoPad because the audio/video appear correct within the software (both in wave form, video track and on playback). There's nothing obvious for me try and manually adjust and on the wrongly created ones, the audio is truncated. ** In summary, the only positive change in behavior occurs when UNchecking "keep pitch unchanged." This produces properly time-aligned video, reduced by 4% (as I have set in the software). Unfortunately, the speaker is unatural enough that it is not acceptable for my use. The voice (and timing) within the software before export is what is desired as the previewed pitch/sounds is not as noticably impacted with "keep pitch unchanged" selected. Thanks for your help.

I have the latest version, 8.63. Have not tried what you suggest yet. I will do so and report back results when finished, along with that of some other tests that I’ve performed. Thanks for the quick response.

I have a 1/2 hr video taken on an IPad Pro (with high efficiency encoding enabled) that I would like to edit with VideoPad to speed it up by 4%. Unfortunately, the video and audio drift on export. Plays fine within the software prior to export. I’ve tried converting it to a constant 30fs frame rate first before speeding it up reexporting and does not help. Ideas?
