I’ve had strange results when exporting either to the .GIF and to the .MP4 formats.
These include artifacts generated during the editing process.
If a user of Pencil2D generates a .pclx project file. This can be viewed within Pencil2D by pressing the Play button in the timeline window.
This causes Pencil2D to display the frames in order and if the repeat option has been clicked will repeat this process until the stop button is pressed.
When the Pencil2D user selects export as either .GIF or .MP4 format these screens are grabbed and transferred via the ffmpeg software to the appropriate files.
Thus any artifacts displayed when using the play button in the Timeline window, will be transfered into the files.
The work around I use is to save the file, before carrying out the export operation.
Is my understanding of how these operations are performed within Pencil2D correct?
