cannot seem to get an overlay to be 100% opaque
Thank you for your hard work on Cin. I'm using the latest official release of Cin for Ubuntu. My issue: ------------- No matter what I try, when placing a video cropped and laid over top of another video always has some degree of transparency. I simply want 100 % opaque overlay of a smaller video on top of a larger one in the background. My two video files are h264 from nvidia nvenc in OBS, 2560x1440. They're both the same physical dimensions originally, but I want to crop one of them down and overlay it on top of the other. But it always has some form of transparency. What I've tried: -------------------- I've used the internal crop filters to reduce something. No luck. I've used Avidemux to crop the video and import it as a new clip. No luck. I've tried each and every overly method in the patchbay. No luck. I'm out of ideas. Is it possible to have a video 100% opaque over a larger one in the background? I've even tried to follow this video, and the f_colorkey filter does not work like that video shows. https://www.youtube.com/watch?v=-VpfNBtFqyY&list=PLCI9oI4dS9zxOX_gxl7JlyiIFp... Thank you for your help on this matter.
Is it possible to have a video 100% opaque over a larger one in the background? Yes, see attached. I am not sure what the problem is but maybe another user will have an idea of what might be going wrong. Meanwhile, I will see if I can duplicate your scenario.

--- Hello Phyllis, Thank you for your assistance. Yes this is exactly what I'm looking to do. I've been doing a lot of googling, and old post mentioned to try fiddling with the camerra/projector along with crop feature. I am able to achieve my goal that way, but it is quite time consuming and error prone. It certainly would be nice if a video is cropped, and I select normal (or whichever mode) from patchbay overlay selector and it "just work"
The only idea I can think of is to check in the patchbay if the Fade slider is at 100% and also if its upper limit is set to 100. Also try using CinGG's appimage, it's more up to date than the Ubuntu package.

I've downloaded the most up to date app image, "cin_for_newer_distros.AppImage" as I'm on Ubuntu 21.04. The md5sum for the file was 6053512f2d26fbc13432632eeaa52017 I still have the same issue with this new release as well. Just to confirm my setup and workflow, since I'm coming from Shotcut, and not a cin user historically: Qty (2) 2560x1440p videos encoded from OBS in h264 using 8bit YUV format. I've double checked my "Settings ->Format" and have YUV 8 Bit there, with 1440p as the dimensions of my project. I then open the resources, load the two files. I add each one of them to a video track. They both start at time zero in the timeline. The upper most track, I add a "Scale" filter , choose some small size and Cinelerra just adds black all around the portions unused. If I try the crop and position, same thing. Cin just throws black color around my top most video. I've tried each and every possible overlay mode. I've confirmed that the levels of the fader are at 100 %. Only one or two of the overlay types allow me to see the video in track 2 - the one underneath. But the top most video, has a fair amount of transparency to it and I'd like it to be 100% opaque. To date, the only way I can get the top track to be smaller and cropped and positioned over track 2 with 100% opaque is to fiddle using crop/scale/position filters and then adjust the projector. Thank you again for assistance.

It seem's like cin is not throwing transparency where there should be *NO* video or photo on the upper tracks. On Tue, May 25, 2021 at 9:46 AM nospam me <[email protected]> wrote:
