USB camera recording issues
Screenflow 10 records mac's built-in camera properly.
However, when I plug in my SONY alpha 5100 through an usb capture card, it takes the 16:9 video and stretches it to 4:3. It's annoying. Screenflow 9 recorded that same camera on the same computer properly.
Interestingly, when setting up the recording and rendering the preview of the camera image, it's shown in 16:9 ratio. But in the recording monitor and the recording itself, it's stretched to 4:3.
Best,
Mat

What camera output settings and what settings in ScreenFlow Configure Recording?Mat Milbury said:

Which Mac Model and macOS?
What is the behavior in Quicktime Movie recording?Have you updated to ScreenFlow 10.0.2 and checked again?

It's a no name capture card from amazon https://www.amazon.com/Capture-Streaming-Teaching-Conference-Broadcasting/dp/B095JL29VS/ref=sr_1_6?dchild=1&keywords=capture+card&qid=1624979808&sr=8-6
It's MacBook Pro 16-inch 2019, Intel i9, 64GB RAM, AMD Radeon Pro 5600M 8GB with macOS Big Sur
I'm running the latest ScreenFlow version as of time of writing - 10.0.2
Quicktime Movie records properly.

Having the same problem here. Using a camera with a HDMI to USB Capture Card (from Sandberg). I can confirm it is a problem with Screenflow 10 (or 10.0.2). Had to record a video today and luckily I had the option to record it with an older version of Screenflow with which it worked just fine. Have tried different video sizes and discarding and choosing the camera again but nothing seems to get it working.
Hope it's gonna get fixed soon :)

Hi there! I'm having the same exact problem. I'm currently using Screenflow 10.0.5.
The metadata says the resolution is 1600x1200. But the settings when I'm recording are for 1080 and it doesn't look distorted when I look at a preview of the USB video before recording.
I'm wondering both how to fix the problem before recording and also wondering if anything can be done about the videos I've already recorded. Thanks!
Best wishes,
Mel

the problem only started a week ago and I didn't change my hardware.What changed?
ScreenFlow 10.0.5 was released two months ago.

I'm using an iPhone Xs as a USB capture device and a cheapy capture card off of Amazon.I have one of those $10-$15 ones to test with. The hardware in those may get updated periodically though. I can test with an iPhone 12. If you're going through a USB Dock or Hub that may impact the results.

HDMI to USB video capture device." It allows me to send a clean feed from FILMICpro to my computerSince the phone doesn't have HDMI out I'm not sure how that helps.
Wouldn't it make more sense to try something like Camo Studio which will give you a clean feed out of the iPhone camera?

I am using an iPhone to HDMI adapter:My hunch is that's your issue. I'm not sure that will work as you intend it with current macOS on M1 hardware. It's not something we'd test.
You should test phone lighting to USB into Mac.
I have the exact same HDMI to USB adaptor as you and can confirm that would work too. I'd avoid the dock (as it can impact resolution) and use a direct USB-A to USB-C adaptor.Mel Hopper Koppelman said:
My current set up worked perfectly until a couple of weeks ago and still works on Ecamm Live.It may work with our Wirecast as well which is the equivalent of ECAMM Live.
ScreenFlow is a different type of program. You'd have to test in Quicktime. -

Not using a dock potentially solves one problem but also seems to create a number of others . . .My own tests show that docks can impact video capture. That's not a ScreenFlow issue. It's related to docs and hubs going to Thunderbolt on M1 Macs.

That's fine, but 2 weeks ago I was happy with the video quality and had a set up that allowed me to also capture my high quality microphone and iPad writing. So I need to balance these needs with optimizing video quality.Which brings me back to what changed?

I updated Screenflow to the latest versionCan you downgrade to the previous version you had and confirmed it worked? That could escalate a fix. If you need access to a specific version I can help provide that.

The metadata says the resolution is 1600x1200.Developers may want to know what your frame size options are in ScreenFlow Configure Recording for the source. I'd try this with and without the dock to see if the dock because that will show whether the dock is the factor.
Can you describe the "quality" issue or is it just the frame size at issue?
You state it works in ECAMM but the developers would need a technical description to know what you'd expect.
It's not clear if it's just the frame size options or some other "quality" issue involved. -

What app is that screenshot of?Apple's Audio Midi Setup. In Applications / Utilities.
Definitely check USB input in the same app

Is there a way to slow down the video so that it'll sync up to the audio in Screenflow?If the audio is drifting do a speed change. If the audio is offset then detach audio (if it's part of the clip) and shift it back in sync.

Anything else I should try? I could switch back to FilmicPro and continue to troubleshoot the video aspect ratio problem. . .As per above, developers would like to know how Quicktime X behaves with this workflow.

Mel Hopper Koppelman said:
- Camo: 30 fps (automatic)
- iPhone recording settings: 30 fps
- Audio: 48,000 Hz
- Screenflow timeline: 30 fpsIn my tests, I'm not seeing sync drift (recording for about 1 minute).
I'm using a newer iPhone 12 Pro but I'm not sure if that would make a difference. -

Yes, it works as expected. No ratio distortion in Quicktime (Thanks for that important info.
