Hi everyone, first time posting, sorry if this is a dupe of a known issue covered elsewhere but I did my best to search for it and couldn't find.
I'm trying to export a video from VideoPad, eventually to be on YouTube. The sequence contains several clips, which all come from the same original long video file (it's several songs from a recording of a concert), so there is only one video file used in the project (the original file has been split into two so there is one other unused item in the video files bin, which is the first minute that I cut off when I split this video file in two using the VideoPad "split" function). The audio has been unlinked from the video in all of the clips, although it's all original audio from the same source file, but I had some issues with sound and video being out of sync (no idea how this was happening before I unlinked the audio, but it was), so had to split to adjust.
So the weird thing is that when I export the video as a low quality file or direct to YouTube, everything is fine (except that exporting to YouTube I get laggy/jumpy video, which is why I decided to try it a different way via a lossless export). When I do a lossless video export, though (with all the settings maximised for top quality), the first three clips are fine, and then on the fourth item, the sound is correct but the video is completely wrong - it starts again from close to the beginning of the sequence (ca 0:18 in), and continues - this time with all the transitions correct - to the end of the sequence.
i.e. the output is something like this (A = Audio, V = Video):
A1 A2 A3 A4
V1 V2 V3 V1 V2 V3 V4
I've tried messing around with copying the fourth clip to a different track, slightly altering where it begins etc to see if this jolts VideoPad into treating it properly, I've tried clearing the cache, obviously closing and reloading the software, also "save as" in a file... nothing makes a difference.
Would be very grateful for any suggestions what could be going on!
Further information on the composition of the timeline, in case it's useful:
There are two audio tracks (I use them alternately in order to control the fades in and out) and six video tracks. Video tracks 1 and 2 alternate the clips, tracks 3 and 4 with text items (song titles etc), track 5 the copied V4 clip and track 6 the text item for V4. In the part of the output where it repeats from just after the beginning of V1, what might be significant is that all the text items appear at what would be their correct places in the video: i.e. it is picking up output from all of the video tracks.
The .vpj file is here - I hope this is helpful though don't know if it's any use without having the original media it links to...
