Several files were tested in VP 6.31,  AAC export set at 192, which resulted in 177-197 kbps.  Sounded fine on a decent PC speaker set up.

Upload your clean, original file and link it here.  Someone will export it and take a listen.

Check out the capabilities of WavePad.  Fiddle with compression.

Yes, the FX remained.  In a test of another project that had no effects but similar issues, removal of the transitions led to success.

Does this help?

Yes, that result was seen here in another recent project that exhibited a similar fault.  But, of course, that's an unacceptable fix.  It's being worked on...

Changed all fades to crossfades and deleted the extraneous clip.  No change - truncated at about 3:16.  This is a deeper issue that the techs will soon solve.

Give Express Burn a test drive.

Got word that the devs have been able to replicate the fault.

Oddly, the project exports okay using VP 6.31 in Windows 7.  Same machine, same hardware at 10.

10 is on a  platter and 7 is on an SSD (with much less free space).  Slightly different video drivers and, perhaps, Direct-X version.

I do think it's related to the FX used.

Perhaps.  Yet several recent projects have had the export issue.  Another user had only fade transitions between his clips, as I recall.  No effects.  Export succeeded after they were removed.  Or, with fades intact, the process was successful only after applying the sequence splitting/combining workaround.

More testing with 6.31 successfully exported at 16x9 resolutions below 1920.  At that res or higher the file was truncated.                                                                                         Frame rates and compressor seemed not to matter.  No changes had been made to TAC's project.

Video editing is resource intensive.  What are your PC's specifications:  CPU, GPU, RAM, free space on C:\?

Lowering preview resolution may help.  Right-click in the preview window to change it. Try toggling hardware acceleration on or off, under OPTIONS|EDITING tab, to see if that makes a difference.  Check this out as well. 

If possible, share a project where the freezing is evident.  To do that follow the instructions in the "Tips for getting help..." post near the top of this forum.

If you share the project, as instructed above, someone will check to see if they see what you see.

The link was good.  55 files.  VP saw them all and loaded them into the project, just as it did earlier.

Things to try...

If a clip's video and audio are linked, right-click and UNLINK them.

To the left of the audio track, click the "lock."  That should prevent video changes from affecting audio.

There's also a change clip feature.  In the clip bin, right-click the clip, click CHANGE or REPLACE FILE.  Locate the new clip and click on it.

Again, wasn't able to spot the problem.  The developers are looking into it.

A 1920 X 1080P export went well, after fiddling.

You show me a home where the buffalo roam ... and I'll show you a might messy house.

Can't up load images (Ironic for video forum) else i'd show a screen shot.

See "Tips for getting help..." near the top of this forum for instructions on how to post a link to an image.

How much free space is available on the C:\ disk?  And the specs of your PC??

    During export there are many choices listed in the PRESET drop-down menu.  

                 Choose the one that fits your needs.

No reports on this, as far as I know.

Share that video and someone will check it out.  To do that, see the post titled "Tips for getting help..." near the top of this forum.  It explains how to upload your project files.

Checked several times, using 6.31.  Doesn't do that here.  Always ripples the clips that follow, even if speed is altered (faster or slower) on only the first clip in the sequence.

What are your PC's specs:  CPU, GPU, free space on C:\, RAM?  Video editing is resource intensive.

You've made changes.  No harm checking the latest incarnation of your project.  See "Tips for getting help..." near the top of the forum for instructions on how to upload.

If stereo has truly been recorded, then VP will play the file in stereo.  Let's check it out...

Upload one of these stereo files and share the link to the file here.  See the instructions in the "Tips for getting help..." near the top of this forum.

Check this out.  The latest version is available on the VP WEBsite.  After registering VP, updates are free for a period of time.

Makes little sense;  portable is portable.  Upload the unchanged original to a server and paste a link to it here and someone will check it out.

Another good method Nat.  It can be simplified a bit.  Try this...

1.  Select the clips to which the effect will be applied.

2.  Click FX in one of the clips or AUDIO EFFECTS on the toolbar

3.  Choose AMPLIFY and move the slider to the desired volume

4.  Click the 5th button from the left on the toolbar whose popup reads "Append to chain."

If the selected clips' volume later needs to be adjusted, make the change with the slider, then click the 4th button, "Replace in chain."
