Logitech Web-Cam Driver Update

I suggest that Techsmith puts pressure on Logitech make sure that their web-cams play well with Camtasia.

Reason: currently, I cannot record 1080p video via Logitech C920 at 30fps (5fps max) using Camtasia.

Now Techsmith has this page dedicated to this issue:
https://support.techsmith.com/hc/en-us/articles/115001000652-Camtasia-Windows-Webcam-Compatibility
And it states that it's an issue with Logitech driver interface.

Now, when I use Vanilla "Logitech Webcam Software" that's the actual name, the file comes back at 1080p 30fps.

So the device is capable of sending 1080 30fps video stream to its output. Techsmith replied that "We do directly plug into the webcam driver to get the frame rate that have encoded in their dialog, however the Logitech Vanilla software can override this dialog by hard coding to record 30fps despite the webcam driver set to 5 fps."

I suggest that we escalate this issue, and get some momentum behind the requirement to update Logitech driver's interface.

I'm sure that there are plenty of frustrated Logitech webcam users who want to capture 1080p video (at useful frame-rate) but are unable to do so.

For example, I want to produce 1080 screen casts, where I occasionally 'cut' to a full-size image of a talking head.

Currently, Logitech advertises that their web-camera http://support.logitech.com/en_us/product/hd-pro-webcam-c920/specs
can record 1080 @30fps.

So we want to be able to do so!

If you have a C920 webcam you can download the webcam software. It will record 1080p at 30 fps.

If your computer is strong enough to pull it off with Camtasia running at the same time? Might be a different story.
I have no problem recording my screen with Camtasia.

 And my Logitech C920 at 1920 x 1080 30fps using the software simultaneously.

I have used all Logitech webcams with the same results ... however there is no mention of the Brio 4k webcam by Logitech which will capture  AT 1080 30 fps in cam 9's screen capture function . This is the max resolution and will not capture 4k .

I still need to use cam 8 to capture with a video camera and blackmagic  4k capture card, I then add that capture to my cam 9 project to complete

Well Gary Wagner,
The simple fact that Logitech C920's can record at 30fps at 1920 x 1080 .
Coupled with the fact that Camtasia isn't capable of capturing it.Can only mean one thing.

TechSmith is either unwilling or incapable of designing  a Camtasia recorder that's fully compatible with these webcams.
It's quite clear the webcams themselves, can function without a hitch in their own environment.

So, the problem occurs when they interact with Camtasia. How can you blame Logitech for this?

I agree with your statement. I stopped using any webcam with screen capture function in cam 9. I use cam 8's "record  camera" function which works  GREAT with my Blackmagic Design 4K  capture card and video camera.  I than use the WMV in my cam 9 project.

It's too bad cam 9 does not support capture cards ... because i have both cam 8 and 9 it is not an issue, just odd they omitted the function in cam 9.

Still i use cam 9 every day to produce a video report, and continue to use the platform now for the 8th year .

By connecting to C920 using two other software programs and seeing 5fps as the only option at 30fps.

Well andrew,

You clearly gave up and bought what TechSmith told you Hook,Line and Sinker.

I don't know what programs you've tried unsuccessfully? You should have tried Bandicam.

Here's proof that screen recording software can record a Logitech C920 at  1920 x 1080 at 30fps.

PLUS, record a monitor Simultaneously.

I recorded my 2560 x 1440 monitor and captured my C920 at 30fps as a separate recording.

Here's what the settings look like in Bandicam.

 

But lets see REAL PROOF shall we.
My monitor recorded at 28.25fps and the Webcam came in at a Solid 30.00fps.



So you see, it can be done. It's more like TechSmith isn't concerning themselves with making it possible ........... is much closer to the truth.

Regards,Joe

Hello :)

I checked out the "Bandi ... " Software, you're not going to like what I'm about to write here.


I had compared two images:
one from Camtasia, recorded at 720, and then upscaled to 1080 during the export process, and 
second one from Bandi recorded at 1080.
Unfortunately, the upscaled image from Camtasia came out better: the amount of details was about the same, but there was a lot less visible noise.

I had then further examined the images from Logitech Web Cam Sofware, and I don't see any significant difference between the image the software produces at 720 and 1080. It is my conclusion that software capable of capturing 1080 image from C920 simply does it by taking the 720 image and then upscaling it to 1080.

If you want to have proof of theory then what you want to do is to capture a 1080 @5fps video, say for 10 seconds (don't move in the frame just be static) and then
capture the second video 720 @30fps. 

You're looking for two things: details in the eye, and details in the hairline. The resolution is going to be most visible in those areas.

If you have the capability to use another software that will allow you to zoom anywhere between 500 to 600% into the image, then you will clearly see the difference in the image quality.

Bandicam 1080p @600% zoom:

Camtasia 1080 (5fps) @600% zoom:

Camtasia 720 (upscaled to 1080) @ 600% zoom


Cheers,
Andrew

What you posted doesn't make me feel bad in the least.

I've stated in multiple previous threads.
 Camtasia makes the best screen recorder I've ever used.It's because the quality of the capture is so high that I say this.

I don't own Bandicam, I downloaded it because I was pretty sure it would work.

My point was not about quality.It was that other screen recording programs can capture Logitech C920's at 30fps. So there's no reason Camtasia couldn't do so If they really wanted to.

Camtasia's main recorder is a resource hog."Huge Files"
 It would make more sense if they recorded webcams 1920 x 1080 and Up to lower quality formats anyway.Save most the resources for the screen recording.That's what you should be zooming into.
Who the heck zooms into their face in webcam footage anyway?

There's this one guy that creates tutorials I really like for Photoshop.
  Recently, he's started going into full screen  mode with his webcam.Looking straight at you. As if he's sitting there talking to you. Staring almost.

They way he goes about  it, it obnoxious and bugs me.
If he starts zooming into his face.I might have to ask him to knock it off. Then, quit watching his tutorials if he doesn't.

It's one thing to create an intro in full screen mode, but this guy keeps popping in and out. He's supposed to be showing me editing tricks on images. Not him, it's to much.
