Error -1074396006 "Unknown codec" when creating multiple videos with a system codec
CAR #1077282.
First video created successfully, second video fails with an error -1074396006 Unknown codec. The error occurs only at first run after LabVIEW launch.
With VDM 2018 SP1 this issue was reproducible after almost every LabVIEW launch. Since VDM 2019 it still happens, but quite rarely.
Workaround:
Call IMAQ AVI2 Get Codec Names VI before calling IMAQ AVI2 Create VIs.

AVI file size is still limited to 2 GB for all system codecs
Still no response to SR.
In VDM 2019 this issue was reported to be fixed (archived) under CAR #428570, but it's not really fixed properly and uninitiated testers blamed codecs for that.

Terrible performance of VPx codecs, especially at high resolutions
Bug #1085585.
New VPx codecs added in VDM 2019 take way too much time to compress single frame.
The difference between low and high resolution images for VP9 codec is especially ridiculous, while VP8 simply performs terribly even for small images.
I'm aware that they are quite heavy in general, but nevertheless they have presets which VDM doesn't expose.

Vision Assistant shows incorrect pattern matching results for some images
Bug #1085591.
For some images pattern matching results in edit mode are different from preview mode. Edit mode shows correct matches.

Didn't know this thread existed...
This bug caused a lot of grief. Would have been nice to know. Would have been even better if the well meaning support engineers knew of this bug! Had to abandon the ppl's in the end...
Please fix it. Thank you.
