Hi Jani,

Thanks for the feedback. Image stabilization will be available in OMTake 1.5, which should be released by next week. You're right that it comes with a trade-off: enabling it adds some latency and a slight crop of the frame, so it will be an optional setting you can turn on or off depending on your setup.

Version 1.5 will also add manual image controls: white balance, hue, and exposure compensation.

I'll post here as soon as the update is out.

Kind regards,
Xavier

Hi Xavier!

V1.5 is a great leap forward!

Will try it soon on production environment.

Noticed that there is still that issue renaming the OMT stream if the phone is in horizontal mode.
The Pen icon next to the Stream name does nothing when tapped - only the focus/exposure point is set there..
It would better to set this Renaming to the new Menu and remove the current renaming functions altogether from the Main screen.

I would also move Framerate and Resolution settings to a completely new Cog-menu. This Cog menu should also contain the Stream name -configuration setting. So all or almost all stream specic settings would be found there - which are settings that are seldomly neccessary to be changed and definately the settings that you don't want to be changed accidentally.

OMTake 1.5.jpg (26kb) downloaded 292 time(s).

Also it would be better to move Lens buttons where the other functions like Resolution is set, so them would not be so close to the Start/Stop button and it would be easier to choose them.
Now its very easy to miss these buttons and set focus/exposure instead..

Noticed also when the Settings menu is visible and in the largest size it darkens the video image below.
This is not a good thing because image adjustments are made in that Settings menu and it makes adjusting the video harder.


Kind regards,
Jani

Hi Jan,

Thanks again for the detailed feedback, it's really helpful. For the next version I'm planning a dedicated cog menu for stream name, resolution and framerate, so they can't be changed by accident (this also takes care of the rename issue in landscape). I'll also make sure the camera settings panel no longer darkens the preview, and add an optional "Start stream automatically on launch" setting. For the lens buttons, I'm looking at the best way to keep them away from the record button.

I'll let you know as soon as a build is ready.

Best regards,
Xavier

Hi Xavier! Sounds Great! Would be handy to have Exposure Compensation also on / moved to the Main screen.

Kind regards,
Jani

Hi Jani,

Thanks for the request. I looked into it, and the good news is that lens correction is already there: when you use the 0.5x ultra-wide lens, iOS applies geometric distortion correction directly in the camera hardware by default, and OMTake does not disable it. It costs nothing in rendering time, but it cannot remove everything. Some distortion remains at the edges, and above all an ultra-wide lens naturally stretches subjects near the borders of the frame because of perspective. No lens correction can fix that part, as it comes from the field of view itself.

For wide shots, the best result is usually to switch to the 1x lens and move the phone back a little. The main lens has much less distortion and generally better image quality.

To make sure nothing unusual is happening on your side, could you tell me which lens you were using (0.5x or 1x), the resolution and frame rate, and whether white balance was set to Auto or Manual? A screenshot of the shot would also help. If something in a specific format turns out to bypass the correction, I will fix it.

Kind regards,
Xavier

Hi everyone,

OMTake 1.6 is now live on the App Store. This update is largely driven by feedback from this forum, so a big thank you to Jan (jet) for the detailed testing and suggestions.

The main change is a new stream settings menu, opened from a gear button in the top bar. Source name, resolution, frame rate, OMT quality and orientation are now all in one place. The top bar only shows the current resolution and frame rate, which keeps the camera screen clean, and the source name and quality are locked while you are live so nothing changes by accident during a show.

Orientation now has a "Lock on start" mode: the stream keeps the orientation it started in until you stop it, so rotating the phone while live no longer changes the frame size seen by vMix. "Auto" still follows the phone's rotation as before.

There is also a new option to start streaming as soon as the app opens, without tapping record. It is off by default and is skipped if the device is overheating, which should be useful for fixed or unattended camera positions.

For exposure, after tapping to focus you can now drag up on the image to brighten or down to darken, in 0.1 EV steps. The value stays in sync with exposure compensation in the camera settings.

This version also brings several improvements: the camera settings panel no longer dims the preview, so you can judge exposure and white balance on the real image; lens buttons are easier to hit and taps near the controls no longer move the focus by mistake; after a thermal slowdown, stopping the stream restores your own resolution, frame rate and quality; and long source names are now handled correctly for discovery on the network.

More details and the setup guide are on the website: https://omtake.app/

As always, feedback and feature requests are very welcome here.

Feature request:

SRT support!

Would be very nice to have SRT streaming capabilities also in OMTake!

So remote connections from around the world would be possible over SRT - with the same App :)

Mode should be selectable from the Cog menu.

Yes, there are other apps already, but most of them are not so good and other are just too expensive or has other weird limitations.

Kind regards,
Jani

Hi Xavier!

Looked into this lens distortion issue yesterday. Yes, I had 1.0x lens and then pinced it up to about 1.5x.. and the barrel distortion is quite noticable..

Would it be possible to correct lens distortions more in app by drawing some points and lines and the app would compensate the distortion?

Kind regards,
Jani

Hi Jan,

Thank you for all these suggestions, they are really helpful.

Regarding SRT, I looked into it, but I don’t plan to add it to OMTake for now. OMTake is built around OMT on the local network, and SRT would mean a completely different encoding and transport stack. For remote contributions over the internet, vMix Call already covers this use case very well: the remote guest only needs a browser on their phone, and the feed comes straight into vMix with talkback included. I think it is the best tool for that job.

About duplicate stream names, you are right, this can cause trouble. In a future version, OMTake will check the network before starting, and if the name is already in use, it will automatically add a suffix and show a clear notice, so the stream never silently conflicts with another one.

The option to lock the Start button is a good idea for unattended cameras. I will add a lock setting in the cog menu, which can also be enabled automatically when the stream starts on launch.

For lens distortion, I will first check whether the camera configuration in that zoom range can be improved, since iOS correction should normally handle most of it. A manual calibration tool is unfortunately not planned, as it would add processing load on every frame and impact thermal performance during long sessions.

Thanks again for testing and for the detailed feedback.

Kind regards,
Xavier
