Common File Conversion Questions
Posted by Matthias Kritz on 18 March 2011 08:59 AM

One of OnSync's most popular use is to upload and display files to other users in your session. You may want to present a PowerPoint file, or review a Word file with your colleagues. In order to do that, some files require you to hit the "convert" button before being able to display these files to other users. That will convert the file onto a format which the Flash Player can understand. Some file types are understood by the Flash Player without the need for conversion.

Which files can I open natively, without converting them first?

Files with the following extensions can be openend immediately after upload:
swf, jpg, jpeg, png, gif, mp3, mp4, flv, m4v, f4v, f4a, f4b, f4p, mov (most), mp4v, m4a, 3gp (most), 3g2 and aac.

Out of that list you can choose to convert the following to a smaller, optimized size:
mp4, flv, mov

OK thanks, what about other filetypes?
Other filetypes can either be uploaded and converted, or just uploaded (and shared with others for download, for example).

Filetypes that can be uploaded and converted:
Office: doc, docx, ppt, pptx, pps, ppsx, xls, xlsx and also pdf, txt, and rtf
Video: avi, mpg, mpeg, asf, asx, fix, mkv, xvid and the filetype mentioned in the previous question (mp4, flv, mov)
Audio: wma, wav, wave, aif, aiff, mpa and ogg

I'm having trouble getting my file to convert, it seems the conversion fails, what can I do?

For PowerPoint files:

1. Make sure you do not include macros on your sildes. For safety reasons we have to disable all macros and that should work fine, but there can be cases where the presence of macros will cause the conversion to cancel.
2. Make sure you do not embed ActiveX components in your slides (such as external video). This causes stability issues with the converter.
3. Make sure you do not rely on external resources, such as CSS. Whilst this should usually not cause any issues with the conversion, we have seen cases which made the file unconvertable.

4. Try to make sure Powerpoint presentations are of a standard presentation formats such 'On-Screen Show 16:9' or 'On-Screen Show 4:3'. Presentations of a custom sizes can be rendered incorrectly on mobile devices. 

The URLs in my powerpoint presentation are not clickable, I need my viewers to be able to click on links, what can I do?

When creating your powerpoint, right click onto the text you want to link and manually reassign the hyperlink using the "hyperlink" menu item. If this does not work, make sure to remove any Word Art. Applying Word Art will result in this text being rendered as a bitmap image rather than a clickable link. Remove Word Art styles by right clicking, then selecting Format > Word Art styles > Clear Word Art.
