With a project that has the issue on the timeline, FILE|SAVE AS PORTABLE PROJECT, upload it to a server and share the link here.  Someone will  check it out.

Here's how...  http://nch.invisionzone.com/topic/23659-tips-for-getting-help-on-this-forum/

Don't think so.  This issue has surfaced before.  File a bug report.  http://tinyurl.com/y6rphnhu

Let the green line above the timeline complete, then preview should be smoother.  If necessary, reduce preview resolution via a right-click in the preview window|Change PV res.

If preview is still problematic, please upload your project for analysis.

Share your project.  Someone will check it out to see if they see what you report.  Here's how... http://nch.invisionzone.com/topic/23659-tips-for-getting-help-on-this-forum/

Last noted, there was a 14-day trial period.

Right-click the audio track on the timeline.  There should be an Edit With Wavepad choice.

Be aware that some features in the 'free' version will be disabled after a trial period.  Consider purchasing and registering VP, which is discounted by 50% at this time.

Be aware too that export will be sharp, even if preview isn't.

Check this out.  If you can locate a knowledgeable custom builder in your area, they should be able to access your needs and make sensible recommendations.

Perhaps VLC and WMP have different individual volume settings?

Content should not have been affected by media players;  they read the files but don't write them.  That said, you can try a different VP export format.

If the hole (original) is longer than the fill (the fix), about all one can do is cut something out of the original.  That will create a jump frame.  The fill audio could also be slowed,  or individual words spaced out from one another, though the result may not sound natural.  Experiment.

A clip that's been split can usually be UNsplit.  Line up the mouse pointer on the split line between the two halves and right-click.  There may be an Unsplit Clips choice.  Otherwise just ignore the original split and make a new one where desired.  There will be no discontinuity at the split points.  The white brackets [  ] are used to drag start and end points of clips.

Please upload a typical capture, so someone here can take a look.  Here's how... http://nch.invisionzone.com/topic/23659-tips-for-getting-help-on-this-forum/

No need to upload the project, just the captured file.

If you followed the procedure outlined in the Proxy FAQ there should have been no conflict, but glad you got it sorted out.

As for laptop specs, some ideas here.

Normally, thumbs of all clips should appear.  Switch to Storyboard mode.  Each clip will be shown independently.

Wait for the green line above the timeline to complete.  Reduce preview resolution.

Related info here.   If no joy, upload and share the project so others can troubleshoot it.

Please upload the elements, and a final composite of how you want them to appear.  In this case, the project itself likely won't be needed.

Someone will experiment.

Tested several other 30fps files, of varying resolutions and bit rates.

They succeeded as lossless exports, so other factors are apparently in play here.

Someone with better insight may chip in.

Recent VP versions incorporate caching improvements.

For resource intensive video editing, beefier is better.  Something along the lines of an I7, 8GB RAM and NVidia video 6xx video would be minimal, in my opinion. though some VP users succeed with considerably less.

Prior to loading your project, Clear Unused Cache Files (OPTIONS|DISK).  Right-click the preview window and reduce preview resolution to the lowest acceptable numbers.

If loading is still sluggish or preview is tedious, use the Proxy Editing method described here.  It can make a world of difference on lower-end systems.

We would like to review your project.  Please upload and share it per the instructions here.

Report back.

Here, a 30fps single 10' video would not export as lossless.  When converted it to standard NTSC 29.97fps lossless export worked instantly.

Splitting on the timeline creates a new clip that is seamless.

Apply the exposure effect to the new clip and it alone will be affected.   There's no need to use the blue/red markers in the preview window.

Have you tested shooting at 29.97fps - the standard rate?

Right-click the audio track and EDIT WITH WAVEPAD.  Need more tracks?  Summon Mixpad from your START button|PROGRAMS menu or from SUITE on VP's menubar.

You've tacked onto a very old thread;  best to start anew.

The duration of multiple stills on the timeline can be altered by selecting (highlighting) the images and then changing their duration in the box beneath preview window.  That box is visible only when the CLIP mode tab is active.

Using an unlicensed version?  The latest is here.

Lots of helpful tutorials here.

Need more info - stop back here with specifics.

Just be aware that it is reported the 'free' version will disable exports or limit them to specific formats, and disable some other features, when the 14-day trial period expires.

Purchase VP, and there will be no limitations.  Upgrades are free for six-months, but the version you pay for will function in perpetuity.

What version of VP are you using?  What are your PC's specs?

The export speed depends on many factors, but are primarily affected by the following:

    Computer's hardware specifications (CPU, hard drive, memory, etc)
    Complexity of video (number of clips and effects, length)
    Video export settings, including format, encoder, and rate factor/bit-rate.

If you'd like someone to confirm your findings and perhaps suggest other remedies, please upload and share the project.  Here's how...
