Right-click the audio track.

CPU usage briefly pops up to 4% under that scenario, consistent with what was seen with the earlier described multi-track/effect project. This hints at something amiss with the install or PC functioning. In considering upgrades, some general recommendations.

Nothing remotely like that here. Loaded an effect/track intensive project. Added a blank clip. CPU at about 2%. Then changed duration of the clip. Caching completed in less than 5". CPU peaked at around 40% during that period, then within another 10" or so settled back down to near zero. This appears to be a local issue. Use the latest VP version. For licensed users upgrades are free for up to six months from purchase date. After that, VP will continue to fully function but a fee will be required in order to register the newest. Retain your old install file and registration info.

A matter of settings. Under the preview window, use MATCH MONITOR, to give a representation of how the project will look on your monitor. On the cut off scenes, be sure to type the text within the preview image boundaries. For images/videos that aren't scaling correctly, try applying the Letterbox to Aspect Ratio effect to them. In export, you should be able to select the A/R choice. Upload and share your video and someone will make specific suggestions. This isn't difficult, takes little time and can be private. Just follow these steps... 1. With your project on the timeline, click on MENU at the top-left. Click FILE|BACK UP PROJECT FILES TO FOLDER. Choose a folder and SELECT FOLDER. 2. Locate the saved, numbered folder and upload it to a free server - Google Drive, MS OneDrive, etc.* (Don't upload the export file or only the VPJ.) 3. Get a shared, public link. If using Google Drive click GET SHAREABLE LINK. Click the blue "Change to anyone with the link..." Then click COPY LINK | DONE. 4. Paste that link here, or click the folder, above top-right in this forum, and message it to me. This is private and won't be shared. * Before uploading, right-click the folder, click PROPERTIES. Look at the File Size to confirm that it's not too big for the free space on the server.

Perhaps you need a peppier video card. Developers are working on making GPU take more of the load.

When a blank clip duration in an exiting project is changed here CPU tics up for the duration of caching, then drops back to a very low value. Takes seconds and is normal. Record_2020_09_26_11_44_22_284.mp4

Experiment with the software to learn its many features. SCALE in the Split-Screen effect box will allow the background to show through. BG on track one, 3x3 grid with image C, F and I each scaled to .90...

Resave before closing VP. Save Project File AS routinely, giving it a unique # or name, so as not to overwrite prior saves. Using Save Project Files (no AS) will overwrite. Then you can restore a project to the state it was in when saved. Just double-click the VPJ file (which isn't playable).

Images aren't cached. Not seeing anything near that behavior here... CPU.mp4

For a very quick, smple portrait border in Videopad... Add the Aspect Ratio CROP TO LETTERBOX effect to the image, then add the border. Or Crop a colored blank background image to the desired overlay portrait image size... Topic deletion can be done by request here.

Not seeing what you seem to be describing. Thee is a slight jerkiness when positioning the elements. Be sure that your video drivers and Direct-X are up to date... https://www.nch.com.au/kb/10265.html Under OPTIONS | EDITING tab toggle "use hardware acceleration" and see if that makes a difference. Sliders work well, but it's often easier to move and size images with their handles, in the preview window.

Please share that clip, if you have the time. Upload to a free server, make it public (get a shareable link) and post that here.

That's a YouTube issue, and you may be out of luck. Here's what they say... Replace a video You can’t replace a video because any new video you upload to YouTube will get a new URL. Instead, you can make changes to an existing video: Trim your video: On a computer, you can cut out the beginning, middle, or end of your video. Add cards to your video: You can use cards to add new elements to your video. Cards can show other video titles, specific websites, etc. Change your video's title and description: You can organize and make changes to your video's title, category, description, and privacy settings.

What version of VP is being used? That's shown at start up and at the bottom-left of the VP screen. Here is the latest. For licensed users upgrades are free for up to six months from purchase date. After that, VP will continue to fully function but a fee will be required in order to register the newest. Retain your old install file and registration info. If you take a few minutes to share your project, someone will check it out. Issues are usually resolved quickly. This can be private, and it's not difficult. Just follow these steps... 1. With your project on the timeline, click on MENU at the top-left. Click FILE|BACK UP PROJECT FILES TO FOLDER. Choose a folder and SELECT FOLDER. 2.

Thanks for that. Does appear to be proprietary - not recognized by VP or a viewer here. Perhaps there is a way to convert it??

Interesting thought. Have you filed a YouTube claim, referring to the NCH agreement page linked above? Uploaded your video there and it's fine. If more facts come to light they will be posted here.

What effects, specifically? Here's an NCH product that integrates with VP... https://www.nchsoftware.com/animation/index.html

Shooting with the H264 compressor instead of H265, if possible, should result in better VP responsiveness and caching speed. At export you may still need to drop down to 2K to get accurate results on lengthy projects. That said, after converting one of your files to H264, placing it twice on the timeline and adding slight zoom and auto level effects, the 18-minute 4K export did succeed using AVI format and MPEG4 compressor at 15fps. No compelling reason to use high frame rates IMO. Lapsed time was loosely comparable to that obtained in a 64-bit editor. At 60fps export took several hours. (At 60fps mp4/MPEG4 worked with a single 8' file.)

Think you would have to be more specific about what was seen and done to have the issue replicated. But...https://tinyurl.com/y6x6fqro

If your insert at a split point, the clip will drop in and ripple those to the right. Position the cursor at the split, right-click the bin clip, PLACE ON SEQUENCE AT CURSOR, or drag it there. If you insert in the middle of an existing clip, that clip will be split and ripple clips at its right. To drag a group of clips to the right, click the first clip, hold down <shift>, click the last clip. Drag. Leaves a gap. If the clips snap, hold down <alt> while dragging. The same applies to text or audio clips. Record_2020_09_23_20_15_30_309.mp4

Clear Unused Cache Files and see if that helps. Sometimes a thumbnail will be missing. If it's truly a gap, it should be seen while previewing, and will be very evident in Storyboard Mode.

Humm... Plotting keyframes prior to speed change seems to be the answer. They don't translate when speed is changed. Bug?? One way to workaround this would be to... change clip speed, right-click | COPY (or drag to the bin), click the + on the sequence tab to add a new, blank sequence right-click | PASTE (or add the speed adjusted clip from the bin) export. Use the changed-speed exported clip in the original sequence and add audio keyframes where desired.

Please upload and share the project, in the usual manner. 1. With your project on the timeline, click on MENU at the top-left. Click FILE|BACK UP PROJECT FILES TO FOLDER. Choose a folder and SELECT FOLDER. 2. Locate the saved, numbered folder and upload it to a free server - Google Drive, MS OneDrive, etc.* (Don't upload the export file or only the VPJ.) 3. Get a shared, public link. If using Google Drive click GET SHAREABLE LINK. Click the blue "Change to anyone with the link..." Then click COPY LINK | DONE. 4. Paste that link here, or click the folder, above top-right in this forum, and message it to me. This is private and won't be shared. * Before uploading, right-click the folder, click PROPERTIES.
