Blogger videos not importing to WordPress

I recently transferred my blog from Blogger to WordPress. The process went pretty smoothly. The images and content imported perfectly, but the videos did not.

I had uploaded many videos using the blogger interface (not youtube). The shortcode in blogger looked something like this:

<object class="BLOG_video_class" contentid="(random content  id number)" height="266" id="BLOG_video-f4508438594ae682" style="clear: right; float: right;" width="320"></object>

When I imported the blog to WordPress, the object tags were stripped as I understood they would be (which is why they did not import). Finding no remedy to reimport them, I went about trying to at least relink the videos to the original url’s.

I went through the trouble of relinking ALL the videos using the embed code pulled from the source code of the original blog which looks something like this:

<object id="BLOG_video-f4508438594ae682" width="320" height="266" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" bgcolor="#FFFFFF"><param name="allowfullscreen" value="true" /><param name="flashvars" value="flvurl=http://redirector.googlevideo.com/videoplayback?id%3Df4508438594ae682%26itag%3D5%26source%3Dblogger%26app%3Dblogger%26cmo%3Dsensitive_content%253Dyes%26ip%3D0.0.0.0%26ipbits%3D0%26expire%3D1386352265%26sparams%3Did,itag,source,ip,ipbits,expire%26signature%3DA0360B4D487E953B9B285ED10152068FF58875DA.B47C158D6CBF23DCA4C8DDD28ED55FCAEBAF57B0%26key%3Dck2&iurl=http://video.google.com/ThumbnailServer2?app%3Dblogger%26contentid%3Df4508438594ae682%26offsetms%3D5000%26itag%3Dw160%26sigh%3DDMfIjArAGQhz4_ls0OEtqabgfdA&autoplay=0&ps=blogger" /><param name="src" value="//www.youtube.com/get_player" /><embed id="BLOG_video-f4508438594ae682" width="320" height="266" type="application/x-shockwave-flash" src="//www.youtube.com/get_player" allowfullscreen="true" flashvars="flvurl=http://redirector.googlevideo.com/videoplayback?id%3Df4508438594ae682%26itag%3D5%26source%3Dblogger%26app%3Dblogger%26cmo%3Dsensitive_content%253Dyes%26ip%3D0.0.0.0%26ipbits%3D0%26expire%3D1386352265%26sparams%3Did,itag,source,ip,ipbits,expire%26signature%3DA0360B4D487E953B9B285ED10152068FF58875DA.B47C158D6CBF23DCA4C8DDD28ED55FCAEBAF57B0%26key%3Dck2&iurl=http://video.google.com/ThumbnailServer2?app%3Dblogger%26contentid%3Df4508438594ae682%26offsetms%3D5000%26itag%3Dw160%26sigh%3DDMfIjArAGQhz4_ls0OEtqabgfdA&autoplay=0&ps=blogger" bgcolor="#FFFFFF" /></object>

This seemed to solve my problems. However, the generated code has an expiration and it seems it actually encrypts the url, which means it can’t be properly embedded. (The above code worked a few weeks ago, but none of the vids from blogger work anymore.

Is there any other way to pull the old videos off the blogger site or do I have to re-upload every video I have already uploaded to blogger?
