I upgrade to Vmix 17 and have a problem with External out 1.
I have a blackmagic mini monitor. I produce in 1080p for record and stream but 576i for external out in mini monitor.
In vmix 16 its all right, in Vmix 17 is dropped continuous, sometimes goes fine for a minutes, but return to dropped..
Its a bug? or my mini monitor is dead?
thank you

Hello Tom,

I update BMD to 10.6 (last update) and check it. fail (a lot of drop)
and roll back to 16.0.0.115 and goes fine... :-(

I'm having the same problem as below. Intermittent dropped frames on playback with the BMD Mini Monitor SDI output. Just updated to v.17... 16 worked fine.

I did not see the dropped frames in the vMix interface, just the Mini Monitor output. Everything is 1080/60i. Not sure if it's related, but the system was sometimes using significantly more CPU than it had... sometimes up to 30%.

You can see the problem in the replay at about 48 to 50 minutes in this video. ?t=47m45s It happened other times as well. Any ideas?

Mike

Hi.

I have similar symptoms, but with 1080 50i output. Most of the time all runs smoothly, but then suddenly I get jerky movement for few minutes..

Recently upgraded to NVIDIA 750 based gfx card. Render times and CPU usage got lower but the same issue happens with that too.

Could this be some kind of timing issue in vMix?

Jet,

For your information, BlackMagic have put a new update 10.6.5 on their support website today for the DeckLink Mini Recorder, it should fixe the drop frame issue you are having, when you get on the support page click on the blue read more link and it will tell you what fixes the new update does.

See link to the support page here: https://www.blackmagicde...ily/capture-and-playback


I hope this helps with your problem.

Could you try installing the following plugin update:

http://www.vmix.com/down...d/decklinkplugin4may.zip

To install:

1. Extract dll file from ZIP file
2. Replace the DecklinkPlugin.dll in C:\Program Files (x86)\vMix\avplugins\decklinkplugin with the file extracted

Let me know if this resolves the output problem.

Jet,

Did you manually install the decklink plugin in the zip as per my post?
The update has not been included with .81 as I didn't hear back if it solved the problem for anybody yet.

BTW, the file size of may version of DecklinkPlugin.dll was exactly the same as the original one that came with 17..77. Was there some updates in the code or was it just recompiled?

Examined the DecklinkPlugin.dll that came with vMix 16 and it is smaller in file size. Now testing it with vMix 17..81.


Edit: So far this vMix v16 version of DecklinkPlugin.dll seems to be much stabler.

I've also had issues with dropped frames. It started a couple months ago when we updated vMix. We had not updated it in the 9 months prior to that because we hadn't had any issues. I did another update two weeks ago, and it solved the problem for one week, but then it occurred again this week. I have updated to 17.0.0.85 and that didn't solve the problem. Sometimes it won't show any dropped frames for up to an hour after we start the external feed, but it still has a stuttering effect. Then the dropped frames will start rapidly adding up, and it will go out of sync with the audio very quickly. We also livestream on youtube, and while there is a very slight stutter, the audio and video stay in sync while our external feed goes out of sync and the stutter gets worse.

Any help would be much appreciated. Here are some specs of the pc we're using.

i7 Quad Core
16GB ram
SSD drive
GTX 570

Thanks for your response.

1. Blackmagic DeckLink Quad. 1280x720. NTSC 59.94p.
2. Windows 10 Pro 64-bit
3. 10.6.5

I've tried almost all of the other frame rates and the same issue would occur.

For the decklink problem, the trouble is we haven't been able to recreate the problem on our test machines.
We've tried both decklink quad 2 and mini monitor and they seem to work fine hours on end, so it must be system specific.

If anybody out there with stuttering issues could post their full system specs maybe we can create a system with identical specs to test as well:

1. CPU model
2. Motherboard model
3. Card model and which slot in motherboard card is installed
4. Windows version

Thanks,

Martin
