Created attachment 141228 [details] Sample ODP - Add Fly-in animation to a text box in Impress, and save it as PPT. - Open the PPT in PowerPoint, and simply save it. - Open the PPT in Impress again, and play the slideshow. => There's no animation for the text box. In PowerPoint the animation still appears in the very same file. Setting the same animation again either in PowerPoint or Impress will play the animation in Impress again. Attaching a sample ODP, the ODP saved as PPT in Impress 6.0.3.2, and the PPT saved again in PowerPoint. Observed using LO 6.0.3.2 & 3.5.0.3 / Windows 7.

The problem is with the unusual key times. Dumping animation data gives the following: - good: ... <animate fill="hold" dur="0.5" calcmode="linear" valueType="number" keyTimes="0.000000;1.000000;" values="#ppt_x;#ppt_x" additive="replace" attributeName="ppt_x" paragraph 0, 5 characters target=""/> <animate fill="hold" dur="0.5" calcmode="linear" valueType="number" keyTimes="0.000000;1.000000;" values="1+#ppt_h/2;#ppt_y" additive="replace" attributeName="ppt_y" paragraph 0, 5 characters target=""/> ... - bad: ... <animate fill="hold" dur="0.5" calcmode="linear" valueType="number" keyTimes="1.000000;-1.000000;" values="#ppt_x;#ppt_x" additive="replace" attributeName="ppt_x" paragraph 0, 5 characters target=""/> <animate fill="hold" dur="0.5" calcmode="linear" valueType="number" keyTimes="1.000000;-1.000000;" values="1+#ppt_h/2;#ppt_y" additive="replace" attributeName="ppt_y" paragraph 0, 5 characters target=""/> ... Animations only permit key times in the range of [0, 1], and the first entry has to be 0. Solution: if the key times are outside the range, normalize key times during import, at least both for PPT and PPTX formats. Note: in OOXML format the key times are stored in element 'tav'.
Created attachment 141288 [details] Dump of different animation properties Attaching four dumps of four different cases: - flyin_good.xml: PPT as created in Impress, - flyin_origPP.xml: PPT as created in PowerPoint, - flyin_bad.xml: PPT created in Impress, then roundtripped in PowerPoint, - flyin_PPfixed.xml: PPT created in Impress, then roundripped in PowerPoint, while setting the same animation again. Out of these only the third (flyin_bad.xml) isn't played correctly in Impress. Nevertheless, the original PPT produced by Impress might contain attribute combinations PowerPoint isn't expecting, hopefully the dumps shed some light on that.
