Slow motion video is frozen when I convert to WMV

I have Movie Edit Pro 15 Plus and when I do a segment of video in slow motion, from the Effects Tab, the slow motion shows fine under the preview but when I convert the video to Windows Media the slow motion segment is then frozen. Also on one of the videos it crashed the program with just a few seconds left on the conversion.
My computer is a brand new Dell with a grapics card.
Thanks for any help.

When you say "convert" you must be referring to "export" as WMV. In any case, are you doing an Audio/Video mixdown prior to your export? I think it's helpful to do that. But I suggest you do a "save as" prior so that you still have the file in its rudimentary edit form.

By "Mix Down" are you referring to batch processing? And if so, what is the best way to do that? (by isolating the clips involved? batching the whole thing? I have tried that, and it's not working yet)
When I search for mix down, it only refers to audio and tells me to look for the Mix Down button, which I have yet to locate.
As I am experiencing this issue as well, I would like RedEclipse to respond ASAP to help us resolve this issue, please.

I am using Movie Edit Pro 15 Plus just so you are aware in the event of differences.

By “mixdown” I’m referring to the process that merges all the audio waves into one single track, and all the video clips into one single track, thereby ultimately ending up with two tracks in the timeline: one video and one audio.
Both these “mixdown” functions are found under the same menu at the top:
Edit > Mix audio
Edit > Audio and video mixdown
In the former case a dialogue box appears to simply allow you to name the mix. In the latter case a dialogue box appears called “Merge audio and video” and it has other settings apart from naming the file.
(You also need to be in the main Edit tab mode in both cases.)

If your overall movie project only contains one audio track in the timeline then it might not be necessary to do the first “Mix audio” step, but I still do it so that the files stay in keeping with the program.

And because I like to save the chain of events that I’ve rendered, I also set up two folders: one for “Audio mix” and one for “Audio and video mixdown” and I do a “save as” into those folders for each mixdown process. You can “undo” a mixdown but I like to save the files in their respective order of mixing. It also helps organize the associated files that the program creates. Otherwise you end up with a miasma of files in one folder.

So if you have, for example, a music soundtrack as well as some other sound effect waves added in your project, when you do the “Mix audio” step it will merge them all into one manageable wave track as I noted above. Once the audio is mixed down you can still make any necessary adjustments to the video clips as they are left untouched.

Then, whatever video clips, effects, and titles you have in the timeline can subsequently be mixed down into one manageable video track when you do the “Audio and video mixdown.” Depending on how much RAM you have, titles and effects can cause lagging… but once mixed down they run smoother and it’s easier to check the overall sequences of your timings and blends and so forth.

Also, during this second mixdown process when I’m in the aforementioned dialogue box called “Merge audio and video” I go to the advanced button and slide the quality to its maximum.

Once everything is mixed down, then you will be left with one video track and one audio track. This should give you a reasonable preview of what you will be exporting.

“Audio mixdowns” are really fast and “Audio and video mixdowns” are slow... but not nearly as slow as doing a final “Export.” Therefore, if you still have problems with the track, you can catch them before doing the much longer “Export” process.
Nothing worse than waiting two hours for an export to process only to find out that it’s garbage.

Now you’re ready to “Export” the movie to whatever format you commonly use. This is done via:
File > Export movie > Video as... etc.

I like to export my files as "Window Media export" because the size of the final file isn’t too huge. And I even bump up the quality to 80 and sometimes 85. (I think the default is set at 75.) Increasing the quality too much can considerably affect the size of the file. All told, it's the final medium that you intent to apply the file with that will dictate the appropriate size.

I hope this has been of some benefit to you and helps untangle your questions about the mixdown process. If you have any further questions by all means fire away and I will respond in kind.
