output flicker

skinnyguy

Used SDJ Pro 2.0.0 with ME 3.2.0 and a Denon 6000 and noticed flickering on my main output window. It was mainly when I moved my x-fader, like it was having a hard time refreshing so it would flicker. Only on the extended display. Using 2012 15" mbp with 16 GB ram with a 2.6 ghz i7. Graphics switching is disabled. I think my ME buffer is around 200 or 300? I tried making it higher but I got some kind of warning. On High Sierra. Using HDMI adapter. Also have smc fan control running. Videos are HD from Xtendamix. I definitely didnʻt have flickering when I was on Yosemite. Canʻt remember when I made the jump to HS if it had any flickers when on SDJ 1.9.0. Iʻm guessing something is taxing my graphics card. Any suggestions?

It could be a number of things. Do you have frame blending enabled in the Preferences? There used to be a bug with regard to this that could cause similar symptoms. If you take MixEmergency out of full-screen mode, and have the output window on the extended display, does the output window still flicker? And if so, does the entire display flicker or just the MixEmergency output window?

skinnyguy

Hm. Actually, it mightʻve been with my Denon 8000. Will try again next week when I have some time. Busy weekend coming up. Will try to check the frame blending and full-screen mode options on the extended display.

Just tried with a Hercules Starlight. Frame blending was not checked/enabled. Still flickered when I did enable. No flickering when NOT in full-screen mode. Flickering only when in full-screen mode. Iʻm also testing this on SDJ 2.1.0.

Nick

Can you try MixEmergency without any controller connected (and Serato DJ not running)? Does this flicker?

skinnyguy

Still does the flicker. At first I thought it might be my tv (4k) and it just couldnʻt handle it now so I hooked it up to another tv and my projector (both 1080p) and it still happens.

Nick

Does it flicker if you use MixEmergency 3.1.1? http://www.inklen.com/download/246/MixEmergency3.1.1.dmg

skinnyguy

unfortunately, yes. hm.

Nick

If you don't move your crossfader at all, does the flicker stop? It's odd that it's only or mostly occurring then.

skinnyguy

it only flickers when the xfader moves. it only seems like it does that for a while then goes away. it seems to come back when a new video is loaded. maybe something in buffering to memory?

Nick

That's interesting. I'm wondering if there might be a MIDI conflict, or something like this (the crossfader might be mapped to some control), that is causing the issue. Can you see if the flickering happens if you autofade in MixEmergency without moving your controller's crossfader?

+1 for me on this Nick. I have noticed it recently but it's intermittent. It's like a flickering grey for me - using Mojave, ME 3.2 - Mid 2015 MacBook

skinnyguy

Nick - at the last test I did, it was only my laptop and no controller. xfading either by dragging mouse or by using auto-crossfade button. geeebeee - i think my flicker is different. itʻs like the screen refreshing.

Nick

Ok, cool. When you say flicker, is it strobing? Or is it more like vertical-sync issues?

geeebeee

Hard to explain for me, it's like interference, kind of strobing. It only seems to affect certain transitions though

Nick

Hmm, it's hard to diagnose these sorts of issues without seeing them. If you put the spinning cube transition in the middle (where it just spins by itself), do you see a line "tearing" in the video?

skinnyguy

oh shoot...i had a video but deleted it...iʻll try to make another when i get a chance.

skinnyguy

found it!

skinnyguy

itʻs in the first few seconds

Nick

Wow - it's happening at pretty much every transition there. Can you send me an e-mail (support@inklen.com) regarding this and I will see if a new version might have any changes to the problem.
