14.1 ISO shots - No moving video
Hello,
I just upgraded to the latest rev 14.1 and attempted to test the new ability to capture separate shots using the ISO/Replay feature. I've found that when I try this none of the shots actually capture moving video. So, it's like a still image of the shot that does not move. Audio seems fine.
Is anyone else experiencing this issue?
Thanks!

It works on our testing so in order to help you troubleshoot we'd need more details.
OS?
What are the contents of shots you are creating?
Does the video in question record as a source ISO?

For this reason, when reporting an issue it's best to report exactly what you are doing so we can help you as I'm sure a "no" answer doesn't resolve your issue.-
CraigS Many thanks for the reply.
I'm using 3 BlackMagic Intensity Pro cards and 2 of the additional BM Pro cards, but the 4k version. The shots are layered shots with 4 layers:
Layer 4: Top layer (the only one that changes from shot to shot) : BlackMagic Intensity Pro/4k
Layer 3: solid color layer
Layer 2: 5 sec .mp4 video (motion background) loop
Layer 1: Audio source for all shots, a Behringer X-Ari 18 (ASIO audio device) all capture card audio is muted in each shot.
Note this is a project that was created in the previous version of Wirecast, saving required the project to be converted, wondering if that might be part of the issue. I will do testing later creating things from scratch using a fresh 14.1 project.
After some additional testing since this post:
1: I have confirmed using each capture card as a regular ISO works correctly.
2: When capturing as ISO Shot some shots have working video from the capture card, but others aren't displaying anything (full black screen) and none of them show the background .mp4 playing.
3: Each shot is labeled and I've confirmed that each shot is selected in the ISO configuration.
4: I've also tested with Desktop Presenter, that seems to work properly (besides the same .mp4 background not playing).
A possible bug, on the shot I captured where it records a full black screen:
That shot's name if I change it in the Shot Layers window it does not change on the shot thumbnail, and vise versa. The name that shows in the ISO Shot "Shot" selection dropdown is what shows on the shot thumbnail - I'm guessing this might be because the project was created in a previous version of Wirecast and converted.
Let me know if you need any additional info.
Thanks,
- Marshal

I will do testing later creating things from scratch using a fresh 14.1 project.Certainly, try creating the shots again. ISO recording between 14.0.4 and 14.1 was one of the significant changes. See if it works as expected in a new document.

Sorry I just need to make sure, without ambiguity, what is and what isn't working in a way we can recreate your entire setup.
Keep in mind when doing multiple ISO recordings, drive throughput is an issue as well.
We need the entire setup, each ISO Shot Recording setups. Which ones aren't working, Their specific configuration. What you are recording them all to.
Please start in a New Blank Document created in Wirecast 14.1. -
CraigS Will do. It's going to take some time for me to generate all of those details. One thing that is constant on all ISO Shot captures though is the 5 second .mp4 video loop does not play.

CraigS I created a fresh project and tested with just the .mp4 background loop, that still does not work. I then tried with a loop from the stock library, using the "A slow animated background traveling through open space" loop, that also does not play when using the ISO shot.
I rebuilt my project from scratch and have been able to successfully get proper video from each capture card. So, the only issue that remains is the .mp4 playback. Can you see if that's reproducible in your lab? You should be able to use the above loop I grabbed from the stock library for testing. I've attached the settings used.

Perhaps the MP4s are impacting ISO shots. Can you create an ISO shot with Blackmagic and Behringer only and does it record properly?
We need to see what combination causes the issue so we have to go through a process of elimination and we have to make sure it's only the ISO shot that's impacted. -
CraigS Correct, the mp4 loops play normally in the usual Wirecast work flow, I see them moving in the thumbnail preview and also on the main window. If I record the output from the selected shot normally the mp4 loops are recorded properly. The ISO shot is the only case where the mp4 loop does not play back. I've tested with my usual shot layers and also with the MP4 loop as the only asset in a shot and in all scenarios when recording the ISO shot the mp4 loop does not record properly.
I have also tested with just the capture cards and my audio interface, that is working properly once I started from a fresh 14.1 project.

CraigS Also just to make sure you have all the details, the system I'm running is on Win 10 20H2 (OS Build 19042.746), with an Nvidia 1080IT GPU, Intel Core i7-5930K @3.5 GHz and 24 GB of RAM.

Marshal Arnold 1080TI GPU* sorry for the typo

perhaps you mean Live Area recording? I just want to make sure there's not some variation where it does record in Shot ISO.

So to be clear, when you add the MP4 both the MP4 and the BMD video freeze?-

I just want to make sure there's not some variation where it does record in Shot ISO.I mean to say when recording the normal non ISO shot output, using the record button next to the live stream button, the recording plays the mp4 loop properly. So yes the Live Area recording works properly.
CraigS said:

CraigS said:

So to be clear, when you add the MP4 both the MP4 and the BMD video freeze?When creating a Shot ISO that is just the BMD's and the audio interface this works properly. If a shot is created that uses the mp4 loop and the BMD and audio interface the mp4 loop is frozen when recording, but the BMD and audio is recorded properly.

o yes the Live Area recording works properly.Thanks. That confirms MP4 plays normally and Wirecast records normally. Issue is specific to Shot ISO.
Marshal Arnold said:

Marshal Arnold Thanks for the confirmation.
-
CraigS you're very welcome.
-
Marshal Arnold The result of our investigation, assuming we understand your description correctly, is it's behaving as designed.
Shot ISO will not record MP4 or equivalent media files as such files don't do anything unless live.
To otherwise do a Shot ISO with such a file the recommendation is to duplicate the shot, remove the media file from the duplicated shot, use the duplicated shot as the Shot ISO.
-
CraigS Many thanks for confirming. If this is by design then may I present this functionality (MP4 playback in shot ISO) as a feature request?
I was hoping to speed up workflow by capturing multiple layered shots all at once using this feature, I see technically that does work, but since I use MP4 loops for backgrounds I will still need to composite the MP4 loop background in 3rd party editing software on all shots except the live recoded shot. I was hoping to eliminate that step by using the shot ISO feature. It would be a huge time saver.
Many thanks for your wonderful support and assistance.

Wirecast doesn't play video when it's not live so any playing/looping elements would be frozen. So using video files in ISO Shots isn't currently viable. Sorry about that.
You're welcome of course.
