You now have your edited slo-mo file in the 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 Virtualdub2 to convert your HQX file into a more appropriate H.264 format - which is similar to the original camera file format.
You can follow the steps below to achieve that.
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 'Virtualdub2'...Select the 'File' heading from the top menu (furthest left)... and then select 'Save audio' from the drop down menu.
This will export the audio as a separate file, ready for editing.
The actual details of the audio editing are a bit outside the scope of these pages, so for the purposes of this page, I'll assume you have a nice new edited '.wav' audio file ready for your final output...
OUTPUT
To export your HQX file - together with it's new audio track - follow the steps below:
• Open the file in 'Virtaldub2'
• 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'...'FFMpeg AAC'... 'OK'
• From the top menu select 'Video'...'Compression' ...'x264vfw - H.264/MPEG-4 AVC codec'
(almost at the bottom of the codec list)
• Click 'OK'
• Then select 'File' ..'Save video'...'Save as Type'...'Audio-Video Interleave (*.AVI) '
(Virtualdub2 does show an mp4 output option, but it doesn't seem to work very well !)
Virtualdub2 will then convert your file to a .AVI video clip, with an AAC encoded audio track.
If your final destination is either your computer or You Tube, that .AVI file will work fine as it is.
You may however prefer to convert the file into the more generally compatible .mp4 format
A simple way to achieve that would be to download the free program linked to in the box below...
You can then simply drag your .AVI file into the default settings on that program, to convert the file directly and quickly to a .mp4 version - without re-encoding the file.
