Question / Help Stinger transition not working

[GM Rod]

So, I'm having trouble getting the custom video transitions to work.

Here's a video:

HELP!

 

[Suslik V]

The stinger file has audio track?

 

[GM Rod]

It does not.

 

[Suslik V]

Can you add one (silent track maybe) and try it again.
Is this file .webm?

 

[GM Rod]

if you're asking about the transition file, it's .MOV because I need it to be quicktime for the transparency.
The file I linked up there is .mp4

 

[Suslik V]

There was something similar in the thread: Stinger transition cuttting video too early. When the file from the mentioned thread was re-encoded to vp9 - it works fine for me.

So, you are using other type. Can you post MediaInfo (.txt) of the file?

 

[GM Rod]

Ok so a little update. I installed the plugin that does this, I guess it's from before OBS itself had it.
For some reason, it WORKS with the plugin, but not with the transition I posted here. Other ones work though, and they're all Quicktime RPG+Alpha .mov files...
The only difference with this one I linked here before, is that it's much longer and it's actual 3D graphics in it (but the FILE is standard video)

 

[GM Rod]

It's gotten worse now. When I try to use that video, it crashes OBS...
Here's Mediainfo:

FFmpeg can't encode this format right now, so I can't test it. But the solution from the link posted above works good with the OBS Studio v21.1.0.

You can try it too, for example:

ffmpeg -c:v libvpx -i LGTransition_straightPNG.webm -c:v qtrle stinger_file.mov

the resulting file (.mov) is huge, but it works (tested with ffmpeg-20180324-db2a7c9-win64-shared).
There -c:v libvpx before -i is important part to decode .webm with alpha. I think, you can try -c:v cfhd or so.

 

[Suslik V]

Can you post the crash log as well?

 

[GM Rod]

It's not technically a crash, it just stops responding and I have to close it. I think it's overloading the CPU. It goes to 100% usage when I do it...

 

[Suslik V]

Unfortunately, .mov with qtrle encoder is only option that has nice balance of quality and performance. Many other formats either proprietary or/and has 10-16 bits in output that require additional resources. The open VP9 (.webm) with 4:2:0 subsampling and alpha is nice, but I think it require updates of the OBS Studio libs (old dependencies used). Movie as alpha channel in filters not supported yet. Thus, the room for experiments is not so big.

 

[GM Rod]

Yeah I kinda gave up on it for now. Thanks anyway!!

This is crazy. How come noone had an answer to all the stinger issues people are having? Im sleepless over this

My stinger transition sometimes lags and makes weird crackling noises

Hello, I am having this same issue. Please see below for the viewable issue, as well as the transition file itself:

Transition is 2secs. Transition Point is 1000ms. Setup as a stinger Scene Transition.

Sometimes the animation works perfectly fine; other times it does not. 100% of the time the "preview" under transition properties, it works. When it comes to using the actual scenes, it rarely works. I have a good PC. It works perfectly when using StreamLabs OBS. But the second I use OBS.Live (which is what I was hoping to switch to) it starts giving me these malfunctions. Any answers? @Suslik V

*also, crash reports are empty. Idk if thats because I dont have it setup right, or that there just isnt any crashes to show.

Thank you all so much!

 

[Suslik V]

@KamiTheBunny I don't know the open source tools that can convert your file to mov with more reliable codec for OBS Studio. So, best solution is to get the source and encode it directly into the mov qtrle.

WebM with alpha channel is not the best choice for the Stinger transition in OBS Studio. Stop using it. What works well for Google, not always works well for creators.

I am a windows laptop user, I tried everything.. Changing the Stinger format, changing the Transition point, changing the FPS of Stinger but nothing worked.

FIX FOR ME -
But what worked was so weird, after plugging my laptop to charging everything worked... no lag, no stinger transition cutting.

Strange that transition optimization issues are still a thing. I've tried a webm transition only to go back to mov because it yielded lesser CPU and no audio choppiness, even though the file size is greater.
