I had never used this part of the program and have just tried it.
I never realized just how useful this could be for tutorials. Thank you for pointing this feature out.
I tried this using a two minute video clip to talk alongside, and sad to say I can't find a fault with it. It recorded the entire length.
Are you sure you have the project markers set for the entire length you want to record to?
A few screen grabs using 'Print Screen' on your keyboard and saving in Windows Paint to upload here using the blue upload symbol above that appears when you reply, to upload images showing 'The project timeline,' 'The settings in the program settings for GPU usage', and 'audio settings' as well as how you set up the audio recording would be really useful.
Also a full system spec of your machine in your signature would also help a lot.
I have many 2 to 3 second audio recordings that were supposed to be longer.
There are 2 things to watch for.
1. If a range is set somewhere, anywhere, on the timeline, the maximum audio recording time will be the length of the range. This is most annoying as often a short range is set by making a transition. So, before recording, double-click the range bar (blue) to remove it, or set a range for the maximum duration that you want the recording to be.
2. On the recording screen, if "Play while recording" is checked, then you need something on the timeline to play. If there is no material or if the playback marker gets to the end of the material, your recording will automatically stop.
3. Not a problem, but you may want to watch and adjust where the recordings go and note the filenames. By default, they will be under the path set for "Recordings" in the Program Settings, Folders tab. I have not, so I have a potential file management problem as all of my recording are in the same place. Note that the filename will be the Movie name (not the Project name unless the same) with - 000x appended.
I suggest that you watch my tutorials below to see many of the features of the program. Most are lightly covered for brevity.
Those are the In and Out points of a Range, not Project Markers. Project Markers are not the same but simply markers to which you add a name. They do not affect recording or playback, but are just visual points for the user.
Here is an illustration showing both a range and Project Markers. Project Markers are automatically numbered.
You can jump to a particular Project Marker using Ctrl+1 to 0 - up to 10 PMs where 0 is 10. Otherwise you can use Cttl+Shift+PgDn or PgUp to move the playback marker to the next/previous PM.
Look what is under Edit, Markers and you see the various ones available: Project Markers, Snap Markers, Chapter Markers and Range Start and End. Under Edit, Move View, you'll see the various ways to jump to them.
I thought that I had explained it all in my first post. Please look again.
To point 2 - add that if "Play while recording" is not checked, you can record beyond the end of any other material on the timeline, or even if there is no material. However, if a range is set, then, as far as I can recall, the range will take precedence.
There was no need to remove all markers, just the range, as I pointed out.
I assume that you are a new user to Movie Edit Pro (MEP) and have come from a different video editing program.
As has been mentioned before @browj2 has created a whole series of beginner and more advanced tutorials on the use of MEP, a complete list is here, this also includes some more advanced procedures, although it refers to Movie Studio 18, which is a variant of MEP, the tutorials are made with MEP.
For posting a sequence of menu selections use one of the abbreviated forms in bold, or italics, as shown below:
. . . . Edit > Edit range > Insert blank space . . . .
This does not do what you want.
This command inserts a blank space on track 1 where a range is selected, if there is an object in that range it will be split and the blank space inserted as shown below and all objects on all tracks will be moved to the right - not shown in the clip below.
When narrating or using text to explain something about an action on the screen for a tutorial I use the Insert still image at the playback marker option, then adjust the length of the inserted image to lengthen the run time as required. You can see this in use in this tutorial - there is no audio, the pause are for the viewer to be able to read the text.
