You now have your edited slo-mo file in an HQX format.... which is fine for editing, but not good for presentation... so you will need to consider your options for the output file format...
You can use Virtualdub to convert your HQX file into a more appropriate H.264 format - which is similar to the original camera file format. Virtualdub will only export files with an .AVI extension, so you may want to convert them ultimately to mp4 for maximum compatibility...
You can follow the steps below to achieve that. Firstly though, one more download!..

Add the 'x.264vfw' codec to Virtualdub by RIGHT clicking on the box below - 'save link as' or 'save target as' and save the file to your 'slomo' project folder.

x.264vfw CODEC

To install the codec, DOUBLE LEFT click on the downloaded .exe file and follow the instructions. The codec should now appear in your Virtualdub list of codecs. To view this, open Virtualdub and from the menu along the top locate 'Video'.... then select 'Compression' to view all the codecs currently available in Virtualdub...'x264vfw' will appear at - or near - the bottom of the list.... you can then close Virtualdub.

AUDIO -
On the previous 'Using Avisynth' page I mentioned that the audio for your new slo-mo clip will now be incomplete....
Converting your video to HQX will have automatically created a new linear PCM ('.wav') audio track, which you will need to extract from your edited slo-mo clip, and edit in a separate audio editor.
To extract the audio track from your HQX video file -
Open the video in 'Virtualdub'...Select the 'File' heading from the top menu (furthest left)... and then select 'Save WAV'. This will export the audio as a separate file, ready for editing.
The actual details of the audio editng are a bit outside the scope of this page, so for the purposes of the page, I'll assume you have a nice new edited '.wav' audio file ready for your final output...

To export your HQX file - together with it's new audio track - as an x264 file, follow the steps below -

Open the file in 'Virtaldub'...
- From the top menu... select 'Audio'.. then 'Audio from other file'... select your new audio '.wav' file as the source for that
- Select 'Audio' from the menu again, and select 'Full processing mode'..
- Select 'Audio' for the 3rd time and then 'Compression'...'AC-3 ACM codec'... '256KBit/s'... OK
- From the top menu select 'Video'...'Compression' ...'x264vfw'...OK
- Then select 'File' ..'Save as AVI'...

...Virtualdub will then convert your file to H.264 video, with a Dolby AC3 audio track. The file extension will still be .AVI....
If your final destination is either your computer or You Tube, that file will work fine, but as suggested above, converting the file to an mp4 format will give better compatibility.
There are several ways to do this. One simple option would be to download the free program linked to in the box below...
You can simply drag your new .AVI file into the default settings on that program, to convert the file to .mp4 without recoding the video.
The audio will automatically be re-encoded from AC3 to AAC, for greater mp4 compatibility

There are of course many different options to perform this task - as with all the other tasks described in these pages - but these notes offer one way to realise some of the potential of MVTools, which can seem a bit difficult to deal with, at the outset.
