VS10+ bug when using distort clip and transition

[jparnold]

I seem to have found a bug in VS10+ when two adjacent clips have 'distort' clip applied and a SLIDE transition between them.

Firstly the distort clip is applied to 'drag' a two adjacent clips shot at 4:3 to 16:9 and then the CIRCLE (under WIPE) transition is applied between those clips.
When I preview that part of the timeline just as the transition finishes the right side of the second clip is squashed to the left and the clips seems to resort back to 4:3 and only fills 3/4 of the left side of the frame.
I thought at the time that this would not occur in the finished rendered movie BUT it DOES.

Am I putting too much 'strain' on VS10+ or is this a BUG?

I done a short test, and this does happen. I noticed that the Circle Wipe is the only one the produces this movement to the left. I would say this probably is a bug. However considering the bizarre actions you're applying, I don't think that Corel would consider it a bug. Even so, they probably would not issue a fix, considering it works as it should on the common applications of it. In other words, using a 4:3 clip in a 16:9 project is what they would consider not the proper application. You should match project aspect ratios with that of the video clips.

Yes I agree it is a bit bizarre what I am doing. This resulted from starting a trip with the camera accidentally set to 4:3 instead of 16:9 for the first day. To salvage it I have used distort clip (this was suggested to me on a separate question I posted last year).

I have fixed the problem by applying distort to those two clips rendering them to DV and then using those rendered clips to replce the orginals in my project.

You say that Corel probably wouldn't bother looking at the possible bug and I sort of agree but -
There is nothing in the documentation (user guide) to warn users that possible problems could occur if attempting to do "strange/weird things".

I do things which I'm sure that the software engineers probably didn't consider the end user would ever do like splitting the audio (from a video clip) then dragging that audio underneath a different clip and then clearing the mute 'flag' on the first clip (which is automatically applied when you split the audio). This results in a piece of audio belonging to one clip duplicated to a different clip (hope you understand what I am trying to explain). This must put a 'strain' on the software.
It is "do-able" but probably not something which anyone would suggest.

I used to be a software engineer (called a programmer back then) and we often found bugs which resulted from the end user doing things with the keyboard which one would never imagine that anyone would ever do.

What do you think?
