Under OPTIONS|DISK tab, Clear Unused Cache Files. See if that makes a difference. And try reinstalling the program.

Never see "loading effect and transition icons" here - just the Welcome screen (if enabled) covered by the NCH logo for five-seconds at start up. Does it still occur after the program has been launched several times?

Lengthy stuff there, but if you have a reasonably-sized segment that displays the problem please share it as a portable project via instructions in the above link.

Using v.7.11, exported a 1280x720 29.97fps clip, slowed to 30% with 'auto level' applied. It looked as fluid as the export without the AL effect. Also exported a 24fps (assuming that your "240" is a typo) at variable max 48fps. Applied both temperature and auto level. Same result - looked about as expected.

Click the three-lined 'hamburger' icon at the top-left of the VP window, then click FILE menu, then VIEW and Restore Default Layout. If that doesn't fix it, drag the little white bar that's just above the timeline's time scale up or down. To expand/contract a track, click the white chevron, at the left.

Folks want to take a look at this. Upload and share the portable project please - not the export. Here's how... http://nch.invisionzone.com/topic/23659-tips-for-getting-help-on-this-forum/

You can update for free up to six months from the purchase date. An upgrade isn't the full purchase price. And, as noted, your copy never expires; you don't have to upgrade. Try the suggested measures. Please share a project, or portion thereof, so others can analyze it. If something is 'muted' we may spot it, and see how long export takes.

Save your project. Save the installer file provided at purchase. That version never expires. Some general tips... Clear Unused Cache Files, under OPTIONS|DISK tab and try another export. During export close all other programs If an overlay clip is opaque, make sure nothing behind it. Adjust In/Out point accordingly to remove invisible part of the clips. Check for redundant effects. Remove them if you can. Use less tracks if possible. Be sure there's amply free space on the C:\ drive The export time is heavily depends on the complexity of the project more than the output video length. For example, if you added a new video clip overlaying existing clips, VP will need to take the time to decode it when exporting. Decoding and encoding are the main bottleneck. Adding effects on a video clip will also slow down exporting. You can also try the current version... If it has been less than six months since purchase upgrade for free. If more time has elapsed you can still upgrade, but there is a fee to license/register. Should these measures make no difference, please upload your project, or half of the project, where audio is muted. Someone will check it out. Here's how... http://nch.invisionzone.com/topic/23659-tips-for-getting-help-on-this-forum/ Be sure to share it publicly and post the link here.

Tested a static 183x171 gif in v7.11, scaled down 50% in VP and exported at the source resolution. Export did appear to be more pixelated than the output of v7.04, which you can download here for comparison. However, when it and a few animated gifs were exported at 1920x1022 (60) in v7.11 they looked okay. Word has it that some SCALE issues should be resolved in the next release. Perhaps this will affect your results??

Change the export resolution setting, perhaps to 1920x1080. Experiment with others. Use the latest VP version, keeping in mind that a purchased/registered version is good for free upgrades for a six-month period. After that there is a fee, though the purchased copy does not expire. Retain the installer file.

Bear in mind though that the example above resized the 2560x1920 4:3 image using the SCALE preset 4:3 to 16:9 . The result appears to be the same as applying the zoom 16:9 restraint. The letterbox option was enabled only when the export resolution did not match the source. In this instance "auto-match" suggested exporting at the source res. When that was changed to 1920x1080 then letterbox became active. This tested true irrespective of the A/R of the effected image.

What VP version? Share a file that does this and someone will have a look. Upload to a free server, such as Google Drive or MS OneDrive. Make the file public (share it) and post the link the file here.

Best to start a new thread. Be since we're here... Does export fail at different points ... or are there clips missing from the completed export? Install the latest version. If you paid to register your current copy save the installer. That version never expires. And upgrades are free for six-months after purchase. After that, what you download will be a trial that eventually may have some limitations. Bracketing clips to select segments, then dropping them onto the timeline has no bearing on export. It should output the entire sequence. If export completes, but clips are missing, see if the my August 5th, 2018 tip above is your answer. If not, please upload your project. Someone will check it out. Here's how... http://nch.invisionzone.com/topic/23659-tips-for-getting-help-on-this-forum/ Don't forget to make the link public (share it), then paste it here.

Best to start a new thread, but since we're here... Each higher video track overlays the lower tracks. In the example below track one is the background image, track two is text, track three is the yellow .png button, track four is a high-contrast logo created by first keying out (green screen) the background, which was blue, leaving only the white clouds. Add any number of layers, as long as their backgrounds are transparent. From the HELP files...

Baffling. Nat plays the mp4 version fine; here it's a mess, while the MTS incarnation fails on your PCs but succeeds here. Hardware issues? "Letterbox" is not active on MTS export. What are the specs of your son's PC?

One approach (and likely there are better ways which others may share)... Assemble the overlays only - no background - in the preview window, scaled and positioned as desired. In the example below track one is the background image, track two is text, track three is the yellow .png button, track four is a high-contrast logo created by first keying out (green screen) the background, which was blue, leaving only the white clouds. Right-click in the preview window and TAKE SNAPSHOT OF SEQUENCE. It will appear in the bin area (top-left). Clear the timeline, or open a new sequence by clicking the + sign on the sequence 1 tab above the timeline. Place the snapshot on the timeline. Apply the green-screen effect and use the eyedropper to key out the black background. Right-click in preview and TAKE SNAPSHOT OF SEQUENCE. Use that new clip to overlay future projects.

Which project? The 2nd, built from mp4 files. Or the 2nd, built from MTS? If the former, the converted mp4s may be corrupt.

Give them a few more days, then delete. Please do report results on your son's PC, which is likely Intel based. Use VP v7.11. Another setting you might experiment with is HARDWARE ACCELERATION. It's under OPTIONS|EDITING tab.

Took a second look at your mp4 project. Poor preview: freezes, black frame at end of goalie slow-mo, jumpy transitions. Export would likely be the same. The MTS-constructed preview and export here were fine, as you saw. The only very subtle error seen was the occasional extra field/frame at the start of a transition. Video editing is resource intensive, so it is conceivable that PC specs could affect the outcome, especially when dealing with large, high-res files. Some VP users have speculated that AMD processors may lag their Intel counterparts, but that has not been substantiated AFAIK.

Share your project so others can see what you report. Here's how... http://nch.invisionzone.com/topic/23659-tips-for-getting-help-on-this-forum/ In a test here... Loaded a 2560x1920 image into VP v7.11 Scaled it up, using preset 4:3-->16:9 (1.34 horizontal and vertical) Exported at 1920x1080 at default avi settings. "Letterbox" is enabled because the output (1920) does not match the source (2560) resolution. The (scaled) VP sequence screen is at the right, below. The avi export was played full screen in MPC-HC. The image at the left is a still capture of the avi, reduced in size (for comparison here) to match the VP screen. Both show virtually identical content.

This mp4 project was unacceptable, as you reported, though the files looked fine in a viewer. Our experiences hint that various converters/programs don't always play nicely with those MTS files, for reasons not apparent here. You might check camera documentation/FAQs and the like to see if more welcoming format alternatives options exist. In the 25fps final linked earlier there was no issue with the slo-mo goalie shot.

Used the original MTS files this time. A lengthy load, but previewed fine after fully caching. MTS--->mp4 conversions on the earlier project were managed simply as an export in Videopad, one file at a time.

Just a guess, but it appears that the source files are the problem. Upload the original four MTS files please. In what manner did you convert those files? (When you reply here, it's not necessary to include all quoted material.)

Check OPTIONS|DISK tab. It the path similar to this? C:\Users\accountname\AppData\Local\Temp\ Be sure that it is referencing the C:\ drive. It's unclear why VP won't accept content past 3:30, as you have succeeded with much longer projects in the past. You state "no room." Is there an error message? A workaround... Load the project as far as you can get (3:30). Export it as an mp4, confirming that the resolution is what you want. "Auto-match" is only a suggestion, based on source files,. Close the program, restart it, and Clear Unused Cache Files. Import the file that you just exported and place it at the head of the timeline. It's just a clip now, so original source files won't be discrete. Import new files and add/edit them in the usual fashion. When satisfied, export the entire film. Does it still balk?

As noted, the new files were swapped in for the old but their names were different. At load VP thought they were missing and prompted to resolve. The new files could have been found anywhere. If the project is saved anew, that's where VP will find them in the future. It's wise to store all in the same folder.
