I'm making virtual chorus videos and want to select multiple tracks and use some effects on the group, for example, move the group from one area on the screen to another, or zoom in or out, etc. Is there a way to do this in Video ProX? I have see effects like this in other videos and would like to be able to accomplish the same.
Could you please provide the links to the tutorials for this subject? I can't find them and feel this is one of the next steps/improvements I'd like to add to my skills. While I understand the size/position effect and have used it successfully, I don't understand how to select multiple videos (say, windows showing different singers) and then applying effects to them as a group. I've seen this recently in other choral videos. Or is it necessary to output to a file that contains all of the windows and then use that to create the desired result by selecting the section of the newly created video?
Don't apply any size positioning effects as a group setting to multiple tracks. They need to be done individually.
Select one video track and adjust the image to the size you want and then place it where you want it to be by dragging it into position. add a key frame for that video (object) to keep it there. Then drag the timeline cursor to where you want the video to either start to move, change size,or both and add another key frame to keep it to the previous size before you want it to expand or contract or move. Then, over the time period you want those changes to take place take the timeline cursor to the next position in the timeline and adjust the image to it's next size and position. Another timeline marker should then be automatically generated. If it isn't then add one.
Play it back to check it moves where and when you want it to. Repeat for all the other clips you wish to alter.
Remember that the higher the track number that that clip will cover over any lower track number video in the selected area you have moved your altered clip to go to.
That is how I would go about it and what you see happening to a degree with the still images in my video above but exactly the same thing can be applied to video clips.
Go to 4 minutes 41 seconds of my video here to see What I have done for multiple image placements. It may look in places as if there are only four placements but there is actually seven individual tracks used at once in places.
The scrolling text is also using key frames for placement and running speed within the dedicated star fields as is the animated logo at the end.
Thank you. I tried selecting multiple videos and applying size/position to them with start and end keyframes identified and it works extremely well for both moving the video(s) and resizing them. Adds a lot of very useful capabilities to video creation! From some testing I did I assume that keyframes only apply to the size/position effect. Is that correct?
Key frames can be added to twisting, twirling, spinning effects using the 360 controls, as well as automating other effects such as changing colour temperature or to alter sharpness or blur. Any effect that has sliders in effect could be key framed. I have used key frames to start a clip completely blurred and come into sharp focus as an effect. The only limit really is one's imagination.
No, you can use keyframes with almost any effect, including on audio.
Any effect that you apply goes to the keyframe area. Some have dropdowns with each element that can be individually keyframed. You can also turn on the effects curve in the timeline and you'll see the nodes. With VPX, you can click on the smoothing button in the keyframe area which is an automatic Bézier curve; clicking on it a second time gives you manual Bézier curves and you can adjust the curve handles of the nodes.
In the image below, I have turned on the curve on the object for HDR Gamma and adjusted some of the Bézier handles. In the keyframe area, you can see the various keyframes for different effects that I applied.
About the only thing that cannot be keyframed is "Section" also known as cropping.
I should have clarified that when I was attempting some other effects I was trying to select multiple videos and it didn't seem to want to work on them at one time like it does with the size/position effect. But I really haven't yet much with many of the other effects (especially zoom and the like), so I'll just have to experiment more with them. It's good to know that the keyframe will work with other effects, even if it can't be done by selecting multiple videos and trying to do an effect on all of them at one time.
I just tried the Gamma effect on 3 clips and it made keyframes on all 3 at the same time. Just remember that if one of the clips is longer than the others, the others cannot have keyframes beyond their end point.
Also, you can copy effects using right-click, video effects, copy video effects or short cut " - " and then paste them on other objects (shortcut "Shift + -" that is Shift minus key). The keyframes come with the effects. You can also save and reload effects.
