I'm using the 8.00 VideoPad.
I have one nearly 6 hour file that when I was editing it with VideoPad, VideoPad runs like 10 times slower than I have ever seen it run. Normally, when I run VideoPad zooming in and out of the timeline task bar at the bottom is very fast. But with this file it appeared to be about 10 times slower. When I divided the file up into 2 pieces and load each piece in later it was blazingly fast. So being the engineer that I am I decided to determine at what point it would run normally fast and what point he would run slow. In the end, I found that if I just wrote the file without changing it lossless output it would store the file to a new name and then when I reloaded that new file it was blazingly fast.
What has confused me is this file was written with version v7.39 with just a slight audio time correction in lossless mode and I'm trying to determine why it would seem to be a problem being slower than normal. I could provide this file as a bug but it's over get 6 GB in size. I did notice in the lossless file size the input of that 6 GB in just a few hundred bytes smaller in size of the new file. Maybe the audio has something to do with it. But I did not change that.
The file was collected with debut version v5 .49. Then I change the audio/video delay by a few frames. Any ideas? Should I submit a bug request?
