Bug ID: 436967
Summary: Video import's UX does not do anything to caution
naive users about what they're importing.
Product: krita
Version: git master (please specify the git hash!)
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Animation
Assignee: krita-bugs-n...@kde.org
Reporter: griffinval...@gmail.com
Target Milestone: ---
SUMMARY
Right now it's far too easy for users to try and import a whole anime episode.
This is far too much for most computers ram, and thus Krita will crash. As the
given users will often be rather new to computers, this is downright cruel.
STEPS TO REPRODUCE
1. Try to import a video file.
2. Determine, through the current UI, what the maximum amount of frames is that
your computer can handle.
3. Try to figure out how to import exactly 24 frames from a video file.
POSSIBLE SOLUTIONS:
Naive users not understanding RAM is a continuing problem with the animation
parts of Krita. This situation is slightly different from all the others,
because while we usually can't say much about the memory consumption of a file
due to how Krita optimizes layer storage, the imported frames are very likely
all the same size.
So, for example, if someone aims to import 24 frames of a 1080x1440 video that
is RGBA 8bit, then that's 24*1080*1440*8*4*2 = 2388787200 bits, 298,598,400
bytes, or 0.298 mb. If there's less than that amount of free memory, we should
just forbid the user from completing import, and also suggest to them that they
might be better off using a video editor instead of Krita's animation tools.
I am rather inclined to say that we should disable video import till this is
done.
This might also be applicable to the frames import, though, there the actual
size of a clip might be more obvious to naive users.
