Sorry it took me so long to get back to you on this. I gave up after getting really frustrated at the program and used another editor for the time being as the project needed to be completed.
Now, I'm back on VideoPad, using the latest version, and it's still an issue. Clearing the cache and restarting did absolutely nothing— neither did reinstalling or repairing it. But, I figured out how to replicate it (although sometimes I don't need to do this, it'll just be black for no reason). The bug only happens when I put a BLANK color image (using "add blank" or ctrl+k) and place it on the timeline BEFORE my video clip. That then turns the entire project black and I can only hear the audio. It's not a problem with the preview, either. If I try to export it as is, the entire finished product is black with only audio.
But I can't replicate it with just any video clip. Literally any of my other clips on my PC will work just fine with VideoPad, but the bug ONLY happens when I use videos that I recorded with my camera (Canon 70D DSLR). They're in .MOV format but I was told that VideoPad supports .MOV. Even weirder is any other .MOV on my PC works, just not the ones recorded with my camera.
This is an issue that can't be looked past because I use VideoPad as my editor for my college projects. Not having the editor I've used for years is kind of putting me back a lot. It's not a problem with the SD card because I've tried different ones, it's not a problem with the camera because the clips work just fine in other editing software, and it's not a problem with my PC— again: Other software works fine.
I'd be more than happy to give you my PC specs listed below:
CPU: AMD R5 5600X
GPU: RTX 3070
RAM: 16GB DDR4
Over 2TB left of storage on three drives, 500GB available on the drive VideoPad's installed on
I attached a Google Drive link to a test clip that I recorded with the camera I use to record all of my videos. The problem persists with this clip, so maybe you can replicate the bug on your end with it. Please get back to me as soon as possible as I really need to know if I can use VideoPad for next semester or if I need to look elsewhere. Thank you!
