Magic Music Visuals

I'm no longer noticing this issue in the new version! Have not done a formal test but I've been mixing on a project for days and haven't noticed any skipped OSC signals. Will post again if I collect some data. THANK YOU SO MUCH! There are things I can do with MMV that can't be done with anything else.

Nice work!

Whoo! Sounds like a good lead. I'm looking forward to testing that out.

Thanks! That would help. I'm somewhat confident that I've ruled out my python OSC client by counting the misses over the course of 5 minutes using the two versions of that code and also by switching out the server side with the test server mentioned above. Turns out there are zero misses when using ...

Ok, I've removed that bit of complexity and only send 1 message per beat. Unfortunately, the issue remains. I haven't measured to see whether the miss rate went down yet. At first glance, it's possible that it didn't change.

Yes, that's a better design and might even fix 1/2 of the instances even if it's not the root cause.

Yes - that's how the event works. I've tried a couple "reset" times already and shouldn't have left that info out of the description. I've tried values of 0.05 (50ms) and 0.15 (150ms) for the time.sleep() in the following python code: # Send OSC messages. self.osc_client.send(1) def beat_r...

Thanks for your response! Here's the scene. In this screenshot I'm using JpegFolder to switch still images. In the video it's switching HAP videos using an InputSelector. Just pointing out that there's no difference in behavior. If you want a longer video to get a bigger sample for what it's doing, ...

Video demo of bug: https://youtu.be/y7HnZSreFQc I don't want to blame MMV for this yet but I'm having a problem verifying that an OSC message was received by MMV. The terminal window in this video is showing a python script that sends OSC messages on the beat. There are intermittent, random misses (...

Nevermind, I found it in the 2.11 User's Guide under Global Parameters in Expressions.

- Added ability to use Globals as variables in Expression modifier

Is this documented somewhere? Not sure how to refer to the Global from an Expression...

Maybe! I'll check it out soon. Thanks for the suggestions.

Yes - but the GTX actually does not show up in that list. Only the Quadro K620!

I'm still not sure this is right. My goal is to make it use my best video card, but it still seems to lean on the Quadro. Maybe this is expected for some reason. Here is the setting and what happens when I start up Magic. Nothing else is going on on the machine here. Does this seem right? Capture.JP...

Just interested in making it use the GTX. Thanks - I'll mess around with these settings.

I have a Quadro K620 and a GeForce GTX 980 on the same machine. Do I need to tell Magic somehow to use the GTX 980? Asking because it only seems to use the K620 (based on Nvidia GPU Utilization).

Just catching up here - thanks Eric!

Correct me if I'm wrong but it seems like the Magic window is 8-bit when using the VideoFile module, even if the source video is 10-bit. Assuming that's correct, is it possible to build in a 10-bit option? It helps with banding problems.

Globals are super useful - thanks! I would like to add that it would also be useful to globalize individual values. For example, I'm in a situation where it would be convenient to use the same threshold across many modules but a different Scale value, which doesn't seem possible currently. Maybe tha...

Waiiiit -- this doesn't happen when that right InputSelector changes from #3 to #2 or from #2 to #1... so what's the difference?

I still don't get it. A blank input is displayed on that InputSelector, so the other InputSelectors reset to 0? Why?

I'm experiencing about 1/2 the frame rate in Magic (30fps) for ISF (nothing else in the scene) as compared w/ Chrome on Shadertoy (60fps) for the same shader. Is this expected? GTX 980, Windows 10, Magic 64-bit

Ok, here it is. Watch the InputSelector on the right side when the value hits 4.0. I think my particular fix is to set Scale to 3.99, but I still don't completely understand why this happens.

I have a video showing something similar happening. It is related to chained InputSelectors, but I'm not sure I understand it yet. Will post a video later today! I'm in a rush at the moment.

Thanks for the responses!

I'll post some video of it happening with the Midi-Ox logging. Maybe I can try a similar thing with a Volume input and see if it happens with that. If not then we'll know it's specific to MIDI.

Eric - thanks for the response. I have SSD. I might have narrowed down the issue to image scaling. This applies to JpegFolder as well: any time I'm asking Magic to scale down an image/video from a larger resolution, the stuttering appears. But it's way less likely to stutter when the Magic window is...

I'm noticing some blocking/hesitation when switching to large files with VideoFile --> InputSelector. Tried all the "keep in memory" options. What's the logic here - does Magic look ahead and keep a portion of the video in memory? What are the boundaries and limitations? Could this be made...

It does this when my MIDI controller is off, not sending signals. I confirmed nothing is coming through the MIDI channel with MIDI-Ox, so I'm pretty sure it's something in Magic. Also, I just noticed that with two different InputSelectors listening on CC #3 and CC #4, they both reset to 0 at the sam...

Yep, it behaves normally other than the occasional jump back to 0. It's a little hard to capture in a video because of the infrequency, or I'd post a video of it.

Using a configuration like this, the InputSelector resets to 0 randomly. I've used MIDI-Ox to confirm that it's not a stray MIDI signal coming through. For that reason I'm pretty sure it's Magic. This happens seemingly randomly, but it's something like once every 20-30 minutes. This isn't specific t...

great idea. how'd you do the text animation in the intro?

nice & relaxing

looks great and it's 50fps! nice work

@Eric - just want to confirm that the Magic audio player didn't make a difference. The video played slightly too fast as before and using 1.001 speed fixes it. Thanks for your responses!

@Eric - maybe a useful test would be to play it in Magic and VLC or MPC-HC at the same time, let it go 30 minutes and check the sync. I'll try this. I agree that drop frame might have nothing to do with it. In any case, I don't really consider it to be a problem considering your vision for Magic's a...

Sorry, unfortunately I won't be able to upload these. They're really big and my net connection isn't great at home. In lieu of that, here's some detail about the two files where this workaround was needed: MPEG4 Video (H264) 1920x1080 30fps 71880kbps [V: Alias Data Handler [eng] (h264 main L5.0, yuv...

It seems to line up with the speed set to 1.001x.

30 - 29.97 = 0.03

0.03 / 30 = 0.001

Maybe this is related to drop frame?

The video file is 29.97.

I'm seeing the same issue. Why does the video slowly desync with audio from the same file that is played externally? It's easy to manually start them at the same time but frustrating that this isn't a solution without more tweaking and time spent.

Is there a way to guarantee that the VideoFile transition is seamless at the loop point? I've got about 12 VideoFile modules of ~100MB clips loaded and I'm switching between them with InputSelector. They don't always stutter but it often does, at the loop point. I can't figure out why it does someti...

Thanks for the reply! I might not have had "Keep Graphics In Memory" checked when I first asked this question because it's not happening now.

Update: Seems to only happen when Scene Start is checked. When it's checked, maybe it should buffer the beginning automatically?

Three anti-alias modules leads to an unexpected framerate drop: https://www.youtube.com/watch?v=JapK1lHRPxw

Or maybe I'm using this module incorrectly.

I'm seeing a short pause / freeze in when switching between VideoFile inputs using InputSelector. I have a ton of memory so it would be great if MMV could buffer part of every VideoFile input to prevent this. Then again I might just be doing this wrong. Is there a way to prevent it or do in a way th...
