Camera Source Resizing

Hello Everyone,

I just have a quick question...

I am aware on how to hold the Alt Key in order to resize a camera feed source, however is there a way to resize Vertically and Horizontaly independently?

Sorry if I've missed this information in the forum.

  • Not currently. Can you give an example of why you'd want to do that? The developers may want to understand the need.

  • Thanks for the response CraigS.

    Basically, when using a side by side template, the cam source window starts of too small, so when expanding diagonally, it outgrows the template never really allowing one to fill in the empty space of A and B.

    Does that make sense? If needed I can provide a screenshot.

  • Please do explain further. Here's Side By Side using two screen captures but it's the same if I use a webcam though.

  • Same in Wirecast 6.0.8 if that's what your using.

  • Yes, I am using Wirecast 6.0.8.

    I've attached a screenshot to use as a reference point.

    Let's say placeholder B is my Cam view. Using Alt and dragging, I cannot expand B properly enough to fill in the template section without it going beyond the placeholder area, even if I uncheck respect Aspect ratio.

    If I expand any more than what it is in the screenshot, the Cam View or B placeholder would overlap into the template. This is where individually stretching points would be cool.

    Is this because the Cam is a 16:9 Ratio and the Template area is a 4:3 Ratio?

  • In your linked example, you can scale the B camera as well as crop it. You wouldn't want to stretch it as that would distort the image. You will go beyond the placeholder image if the aspect ratio is different. You can create your own templates and import them.

  • I have a similar issue:

    Using a Magewell HDMI capture card into a MacBook Pro, the camera source appears to come into wirecast as a small, SD-like image that I then have to scale up to fill the screen, resulting in a low-res looking image.

    I have tried restarting computer, re-connecting the magewell to the computer, checking my camera output settings (they are 1080 30p) etc.

    It used to work fine. What could be my problem?

    Thank you.

  • Derrick Minyard I'd need more information. Magewell could be scaling if you're only using USB2.  Otherwise the size should be available in System Device Properties. If the device and Canvas are the same size then it should just be 100% in Shot Layer Properties.

    If you want a more specific response, you'd have to provide technical information since you don't list version, OS, or actually information from the various Wirecast Properties panes.

  • Hi CraigS  and Derrick Minyard

    I have seen this many times myself. A friend had this happen today, with a USB connected camera source. Basically, Wirecast gets the screen resolution properties wrong some how semi-randomly. For my friend, this was even more challenging. There were no editable properties for this device. His only solution was to delete the device from the media asset manager and from his wirecast shots, restart wirecast, and then re-add the camera source.

    This problem happens for me using a FaceTime camera. I have documented the problem in the video attached to this post. I did open a ticket at the time with this data, but I have not kept the ticket number for tracking. NOTE: This still affects the current version.

    I hope the data above helps as a workaround for you.

     I have always been able to fix this in any webcam by changing the Properties back to the desired frame size though. Device Properties should allow you to select the correct frame size. It always does for me. Then Shot Layer Properties will always scale correctly to the canvas.

    Yes. Awesome once you know where to look. When I made that video, I had no idea where to look. I also don't know why Wirecast randomly changed resolution.

    But here's one that will stump you. A friend uses a camlink HDMI to USB adaptor. It worked perfectly with Wirecast. Recently, he purchased a new computer. The install went well. BUT, the camlink adaptor had the same problem. The picture was the wrong resolution and proportions. BUT, this device had no properties that could be changed.

    Solution: Delete the asset from the media asset manager, and from all shots... restart wirecast, and then re-add it. But the question still remains. Why is wirecast intermittently detecting incorrect settings? Based on your comments above there you can "fix it"... we know you have experienced this issue too. Did you open a ticket for the problem when you first saw it? 

    (Yes I am being cheeky ... But I am curious if its a known problem, what the status of it is!)

     Given the HDMI to USB devices do scaling in hardware and the OS is providing the USB driver, the issue may precede Wirecast which is only seeing what's handed to it at the end of the chain.

    With Webcams, the parameters presented can be changed. That may not be the case with HDMI to USB devices which, unlike webcams, offer no end control over the settings.

    As per my video - I solved it by opening another application to prove that it was wirecast specific. Ken had the same issue. Today, we had an issue where "full screen" screen capture was not capturing the full screen. Same type of scenario. My rendezvous dashboard frequently has my black magic source camera not filling the window - but its different live.

    Overall, screen resolution detection and rendering seems to be inconsistent and unpredictable. I currently work around these issues with a vert strict set of instructions I follow each week, to do things to workaround the issues. I was even on a call with someone from your support organization this week, demonstrating other issues, and I added a source to a shot... and needed to do manual tweaks to get it to the correct screen dimensions. I do this each and every week.

  • Greg Kuhnert Thanks for reporting that but when you open another program that may trigger another detection just one might close and reopen Wirecast and get a different results the second time.

    Nope. Tried this many times. Once its detected wrongly, Wirecast keeps those bad settings...

    There are lots of other similar issues that are annoying - but to be honest, I'm not reporting all of that just now. My focus and priority is around stability (no crashes), Rendezvous (many fixes that will be in 12), and audio mixer (end of random channel assignment). Those things have no workarounds. Once those are fixed, I'll focus on reporting more of the annoying things that have workarounds like this one.
