Linux, Nvidia GFX, Intel CPU
Broken: Probably all versions
Short description of error
- Tooltips for Frames, Start Frame, Offset give wrong information (and the options are already really confusing)
- Many (Most?) Blender users randomly fiddle with these until they do what they want.
- I'm still not sure what the options mean, and I'm not sure anyone else does :P
Exact steps for others to reproduce the error
What I'm trying to do:
I have Scene starting at frame 101 and ending at frame 300
I have an Image Sequence on disk starting at frame frame_0001.png and ending at frame frame_0300.png
I want to only use 200 frames, matching the scene numbers: frame_0101.png to frame_0300.png.
This will probably be similar for lower numbers.
1- Start with 300 frames of images on disk, with _0001 to _0300 as frame numbers.
2- have a blend file starting at frame 101 and ending at frame 300
3- goal is to load the frames from disk that correspond with the frame numbers of the scene (-0101 to -0300), Shift A, Input, Image, click open, and select all your images and press enter.
4- Frames Tooltip "Number of Images of a Movie to Use":
4a- it's not a movie (should be image sequence)
4b- I input 200 because I'm only going to use the last 200 frames.
5- Start Frame Tooltip "Global Starting Frame of the Movie/Sequence, assuming first picture has #1"
5b- this seems to really mean "Blender Scene Frame # to start playback" I set it to 101, my start frame for the scene.
6- Offset: Toolip "Offset the number of the frame to use in this animation":
6a- The tooltip doesn't actually give any extra information. Since I have frames on disk, and scene frames, it doesn't say which is being offset, nor does it say if it's offseting the number or from the actual start frame on disk or scene, mathematically:
result = offset + a, to make it clear what happens, I need to know what 'a' is - I already know it's a frame in an animation, so the tooltip doesn't actually tell me.
6b- according to Ton It's the frame number that gets loaded. Tests reveal that it is the frame number - 1 (i.e. if I want to start at frame 1, input 0 , etc.) So I put in frame 100
1- the sequence starts playing back fine, starting from scene.frame = 101, pulling image frame_0101.png from disk (success!!!!!)
2- the sequence stops playing at frame 200 instead of frame 300!!!! this is because Frames isn't the number of frames of the movie to *use*, rather it is the number of frames of the movie on *disk*. I have two options:
2b- change frames to 300, then my comp will get 200 frames as desired.
2c- delete the first 100 frames (frame_0001.png to frame_0101.png) from disk.
