Hi!
I just downloaded VideoPad and i also found this cache building. I have used Adobe Premiere Pro before, and that program never builds cache like this.
I thought i should share what i have found after some reading and research on my own, that i haven't seen anyone else pointing out here.
The cache has a limit for each export, project, session, sequence...
Its fairly similar in size to the original file. So i.e.
I had this documentary with commercial and additional 30 min overtime.
Total original size: 3.77 GB.
The generated cache: 3:71 GB.
Exported final Size: 340 Mb
Export time: 1h 22 min.
This is useful information if you dont have a HD with 4 TB free space.
I tend to ready my projects/sessions/sequences before bed, and export during the night. In other video editing programs cache has never been a problem. But VideoPad doubbles the space taken with its Cache. So i always calculate that exporting during the night will take at least the equal ammount of chache-space that the original files are, and an additional 1/7 of space for the exported files.
Why VideoPad does this i have no idea since its kind of redundant to chache original files when they havnt been edited.
I haven't added any effects, nor any new material. I have only deleted commercials in between a documentary.
