I just upgraded to vMix 12 HD and I'm trying to upgrade my stringers to full HD but vMix seems to be fussy with respect to what works well and what doesn't...
I'm just wondering if there is something in my render settings that perhaps influences vMix's playback?
I have always preferred .avi files for SD but vMix and windows are not fond of my HD AVI renders and they do not always provide smooth playback.
Quicktime files seem to work better but I'm having some issues.
In particular, some files seem to play fine initially as stinger transitions but then subsequently hang or rather do not "restart" or respond to shortcut key triggers.
The blue highlight on overlay key activates but video stinger wont play because video is at end, hitting the play button will activate stinger transition but subsequent behavior is erratic, either the same or plays without audio. Closing the input and reloading it seemed to cure the issue on the third attempt, but what is going on?
Other files seem behave perfectly all the time, so I would like to figure out what the issue is...

Yes, vMix 12.0.0.129 x64 installed and running on windows7 i7 950 nvidia470.
MOV clips made with After Effects CS5 and I find my rendering options are somewhat limited (I've never been fond of Adobe's Quicktime render, but HD AVI render's often stutter on playback both in vMix and with WindowMediaPlayer)
Ticking the boxes in input settings had no real impact on the Stinger transition.
As indicated, after re-loading the input it seems to be working fine, I'm just not sure what caused the issue in the first place and was wondering if it is something in the file...

As such, I have included a link to the files for further testing and/or general use by the community:

This is a link to the SD clips in action (the HD clips are basically the same only in HD):

As near as I can figure, the issue is related to the "Duration" setting
The Instant Replay clip worked fine from the get go, no matter what the duration setting (it's a 10 second clip).
The Live Action clip was problematic for a couple of different rendered versions (it's a 4 second clip)
If the duration was set below the clip length, the issue appears...

Settings used:
Number: Stinger 1
Type: Fullscreen
Effect: Fade
Effect Duration: 100 ms
Duration: 5000 ms
Stinger Input: SportsAction Instant Replay Stinger HD.mov
Stinger Cut Point: 500 ms
Alpha: 255

Number: Stinger 2
Type: Fullscreen
Effect: Fade
Effect Duration: 100 ms
Duration: 4000 ms (works fine) 3000 ms (issue)
Stinger Input: LiveActionStingerHD2.mov
Stinger Cut Point: 1000 ms
Alpha: 255

Might take a while...
Live Action Stinger HD.mov
was the initial render and displayed the issue as well, hence why I re-rendered...
Slow internet here so it may take several hours to upload.

The zip file contained Replay Stinger HD.mov and SportsAction Instant Replay Stinger HD.mov

Regarding audio you will need to disable automatic audio mixing and turn on audio manually for stingers.

Both of those files are 12 seconds in length, which is why I need the 4 second clip you mentioned.

Audio settings might depend on the order you added the inputs, but as long as the audio button is green the audio should play.

The first input you add will automatically be sent to output and therefore the audio will be switched on.
All other inputs will have audio off by default, you can see the status by observing the audio button.

If it is green and you can't hear audio then that might be a bug.

The cut point timings may be different due to QuickTime used for MOV files in x32 while FFMPEG is used for x64.

I've been able to re-create the stinger issue under some rare circumstances, still trying to narrow down the cause.
It looks like the video does not start correctly when it happens, clicking the little play button underneath the input
appears to kick start it again and the stinger transition completes as per normal.

Thanks Martin,
I will test it out when I get a chance!
