DCEDIT

Thanks, borate. If I didn't have 16 boxes I might try it

Thanks, Nat. I appreciate the step-by-step. Unfortunately, my grid has space between boxes on all sides, so I can't just mask a section. Sigh. Looks like I will not be able to use all of the row-by-row projects I've created because there is some black in a few boxes. Back to the drawing board. This should teach me not to try to get a jump on a project when I don't have all of the elements in hand!

Thanks, Borate. Still need help. Here's what I tried: Select clip on timeline, choose green screen effect, change green square to black. Export video. When placing that exported video back on the timeline, it still has a black background; an image added on Track 1 does not show through. I also tried to key out the black on the exported video. Same issue. I must be doing something wrong but can't figure out what. Help?

I'm doing another virtual choir project. I have to export each line in a 4 x 4 box separately and then combine them; doing them all at once causes some videos to flash or disappear. (Hardware issue, I assume.) Once I have all of the lines, I will overlay them to form a complete grid. Then, I want to add a video on Track 1 so it's behind all the boxes. I can't do this as I go along because the background video isn't ready. Just ran a test with one row of boxes and an image added to Track 1 doesn't show. The boxes are now on a black background. I should add that the exported test of one row of boxes had nothing on video Track 1. I could swear I did this before but it's not working now. Borate, I could use your help again. Thanks!

In case it's helpful to others, here are the vertical and horizontal positions I'm using (with clips scaled to .16). There is space between each clip in this configuration so parts of a background image can be seen. -41 -24.5 -8.4 8.4 24.5 41

Thanks Nat. That's what I started doing based on your 10 x 10 advice, although I didn't have much luck dragging the clips. Too much lag in my system. Typing in values for vertical seems to work, though. Hadn't thought of aligning them all left each time and then positioning. That should save some time! Thanks again.

Sorry to say, I'm not managing to get the clips to move far enough over to fit six across. Even with horizontal bias set at 0 for each clip. There doesn't seem to be a way to go below 0. It doesn't work any better trying to create a row of 6 using vertical bias. The suggestion here https://nch.invisionzone.com/topic/31417-no-video-in-exported-file-choir/was for a 6 x 3 grid, so the editor was able to build by exporting the 3 verticals at a time. Sadly, I need 6 in both directions. I see Nat's math here: https://nch.invisionzone.com/topic/31823-100-clip-multi-screen-method/ for a 10 x 10. Looks like I will need to come up with position values for 6 x 6. Does that seem right?

Thanks for that. If I'm reading the right entry, the suggestion is to start with a 5 x 5 and then scale and move each clip using the horizontal bias control. It's certainly easier than doing math, but it's going to take a while, I can tell. By the way, I've been having to export for every two horizontal rows in 5 x 5 as it is to make sure everything plays correctly. I blame my hardware for that issue. Think there is any chance VP will ever expand the grid options?

Updated question: Is 5 x 5 the biggest available split screen grid? Hard to believe, but I now have to do a 6 x 6. Could I use 5 x 5 and offset everything to the left, somehow, leaving one column that I would have to scale and position manually? Hoping there is a shortcut. Thanks for your help.

Perfect! Thanks so much. You have no idea how long it took me to do this "manually," creating a grid on paper and assigning locations. I may not tell our choir director how much easier this is now, lest he expect it every week

Thanks, Borate. That doesn't quite do the trick for us, since we are trying to have the faces superimposed on an image, as in this example: https://drive.google.com/file/d/1RqedNkt_363HeZW-8P32k_VDrZ_Hn3xr/view?usp=sharing That was the start of the piece, with more boxes added as the different voice parts entered. To build it, I had to calculate the placement of each image. I sure would love to use a shortcut!

Borate, you are a genius. Thanks so much for this! One more question, however. Is there any way to allow for space around each of the boxes in the matrix? Our choir director wants a background image with the boxes superimposed on top, and from what I've been able to tell, the grid fills up the entire screen so the image doesn't show. Thoughts? And thanks!

Thanks. I think I've figured it out. I should have been using just Zoom in order to set keyframes, right?

I'm trying to add a pan/zoom to a clip and I can see the effect animation editor window. But the GREEN + button at the top seems to be grayed out. Clicking it does nothing. So I can't add a keyframe to set the start and end of the zoom. Help would be greatly appreciated. Thanks! The version of VideoPad: 8.23.

Thanks so much. I'll give that a try.

I'm trying to tweak a clip to fix a lag in the audio, matching it up to the video correctly. The clip plays fine in VLC and the built-in Windows 10 player but it is out of sync in VideoPad 5.32. I have unlinked the audio and video, but when I shift the audio, the video track disappeared. The same thing happens when I shift the video--the audio disappears. I searched the forum for advice on this but didn't find anyone else asking about this particular problem. Of course, I'm on deadline. I could really use some help. Thanks!
