14.2 break realtime (solved with 14.2.1)

on my machine at home...

files that work well in 14.1 (alexa prores) crash the system and play at 14fps.

i have a 1200mbs raid and a gtx 1080 ti...

downgraded,.....

Hi,

Going to V14.2, I had a slowdown the first time (a UHD normally read at 24 fps but that did not exceed 15 fps).
I turned off playback performance mode, next started play the clip for a few seconds and reactivated performance mode after: everything works well after.

I'm doing OK with 14.2 on a full-tilt Trashcan Mac at the moment, about 18-19 nodes, light NR, some OFX, several windows & blur nodes, all real-time. I've only been using 2K ProRes 444 source files so far, but I believe I'm starting a 4.6K CineDNG project later on in the week. We'll see how it goes.

i will try

I had something similar but with BMCC raw files. All the other projects were fine. Sometimes it just crashed opening that project, other times I could open it, play in Color, Fairlight and Deliver tabs, but when playing in the Edit tab it crashed. Tried several times. The stranger thing ( ) is that the same raw files played out nicely when I opened them in another already done project. Had to go back to 14.1.1 to finish the project and now I'm starting the day with the 14.2 and hope it will work fine as it seemed to.

Also, i added 3 clips in 14.2. Just aces to media pool and in the timeline. They did not show up in 14.1, i had to re-import

That should definitely not be happening. What source file format?

Those are Alexa prores files 2k

That should be easy. I'm stumped!

Not that this will affect anything, but what if you start a new project NOT in ACES and bring the clip in. Does it show up?

I have been told that dragging-and-dropping clips into the Media Pool is a little buggy for some users, but it's not something I often use.

Walter, are you in Mac or Windows? As we had probably the same error/bug, we could start nailing it down.

No problem here on Windows with Alexa 2K Prores, ACES or not, drag & drop or via Media Browser.

If there's anything you can release, I'd be happy to try it, pm me.

it's a pc, windows 10.

I can probably post a clip, i need to ask.

Windows 10 too. But as I said, it happened with a project already created with 14.1.1, BMCC Raw files. But the same files had no problems opened in another projects. All ACES. Also I could play in another tabs, only problem with this particular project was hitting play in the Edit tab.
Very strange... Did you have a similar behaviour?

[Humbly, English is not my native language ..]

I downloaded from the ALEXA site (ftp-footage.arri.de) a 2K and I created a project in ACES cc (1.03)
IDT Alexa ODT Rec.2020
Drag a S001C002_161207_R6ZJ.mov clip from the explorer directly to the media pool
Create a TL
No LUT called
No issue
I do not know what to say ... source (camera) problem? (or is me?)

Walter, are you using the retime function? I'm starting to think it might be the issue. Otherwise, the only candidate remaining might be a corrupted project

It's weird, the project was playing perfectly fine in 14.1, in 14.2 was stuttering with nothing else changed but the upgrade, then downgrade to 14.1 again, no other changes, and is play just fine...

I will try to upgrade again in the next week or so.

Exactly the same here.

yep, update again, no changes to the project/files, no real-time. I tweak the optimization playback to no avail. downgraded and all is fine...

Jean Claude , try to create the project in 4.1, do some color, then upgrade to 4.2: does work for you?

Walter, if you can post a link to a clip and .drp of a simple project that you're seeing this in, I can check it out for you on my machine.

I did the following tests:

Have you tried testing with the Source Clip S001C002_161207_R6ZJ.mov (http://www.arri.com/camera/alexa/learn/ ... e_footage/)?

(IDT ALEXA ODT REC.709 is even better ... )

Thanks for the Test.!!!

I downgraded the video drivers to 10.9.5 (i was having weird flashes to the mini monitor PCI).

then try upgrade again, stilll no realtime.

export a drp in 14.1, import back in 14.2 and it seems to have fix it...

nope spoke too soon: if i disable the output card (minimonitor) altogether it works, otherwise doesn't

Good news and interesting to know that by exporting / importing a project (.DRP): it can solve some issue (s) between version. Thank you.

Edit: have you tried the V10.9.7? Did you have a firmware update? After installing the V10.9.7: Have you rebooted your PC? (sorry: not easy)

here logs and database

Hi,
As you have put your logs in public => I allowed myself to open your logs: on Windows OS => never have first HDD (Cache and other) system HDD => C:\ (by default) ).

One can not exclude from the part of Windows to do in a work internal to the OS (on c: \ => pagination or other)) in parallel with a work in Davinci Resolve (work independent of each other without internal communications between works)

My advice: have another internal HDD for the cache and another for the masters. I hope you have better advice from others. Sorry.

The material (and cache) is on c\jobs that IS a separate drive, a 50Tb 8×8 7200k enterprise class (SAN TYPE) hdd, 1300gb speed drives.

Add i mentioned, 14.1 play just fine, 14.2 nothing changed, stutter, downgrade to 14.1 again, just fine....

here one of the clips

Don't know whether it's good news or bad, but I had no trouble playing the clip in 14.2 (Win). You've got a real puzzler.

Perhaps an audio sync problem?
I would verify if your audio driver is setup at (a multiple of) 48K.

Walter, do you have a 3D LUT for output video monitoring? (To calibrate you reference monitor). Because that's my setup and I also have slower playback with 14.2 (14fps vs real time) but when I remove the video monitor LUT, all is good again. So it would seem 3D video monitor LUT's are more taxing on 14.2...?

I encountered the same kind of thing with Resolve 12, and that's one of the things that led me to abandon display LUTs from within Resolve and just go with an external LUT in a LUT box.

My lut (standard Alexa lut) is in the timeline

Disconnecting the drive with the merits still does not give playback, delete tineline gratin ofx and lut still dies not give playback

Hi Marc. Yeah, I've been thinking about a LUT box for a while now, I don't like the idea of wasting precious GPU ressources for a monitoring LUT...

Walter, could you possibly also post a .drp of a simple project that is setup for this problem to occur in?

EDIT: Actually, I just noticed the link to the .drp and logs. So I'll give it a test when I'm in front of my desktop.

Hi Walter,

I placed your clip on a simple HDD 7200 rpm (W/R 135 MB/s).

I tried your clip in your project, I just changed the 3D LUT timeline (missing: a01_alcawg_to_bt1886) by Arri Alexa to logC to Rec709 and no issue reading from the color tab.

I also increased the size of the data burn-in for the screen copy. I used my 3D LUT Color viewer for my monitor and used my Decklink 4K Extrem => no issue

Hard problem ... If it works without activating the external monitor via minimonitor, this may be the cause of the problem? I hope BMD will be able to solve the issue.

(I blurred the image ...)

My test was with the mini-monitor, and with the latest video drivers (earlier ones weren't working with 14.2). I tried ACES and the Arri LogC timeline lut, but didn't use the project file, having assumed Walter would have tried new project creation in 14.2. I'd suggest he downgrade to Win7 (like me), but that would be an unkind joke.

Sounds like maybe a defective mini-monitor or some kind of video device driver conflict unique to 14.2?

Lol, w10 is not playing nice i might consider just downgrade..

I tried with both last version on desktop video for the mini monitor: project work fine with 14.1, does not play with 14.2.
I'm pretty sure that if i start the project anew in 14.2 It will be fine, but this was started in 14.1.

Even with just the drp loaded and no media does not play, i wonder if there something wrong in the user preferences that I'm not see it: that seems to be the only practical difference unless the software itself had s bad time with the database.

I wish Dwaine had 10 minutes to look at the logs and see if something obvious is going on...

Going whole hog, I opened the project, imported the clip and created a timeline for it. Playback was fine on the mini-monitor. The only oddity I saw in the Preferences was you have monitoring set to the PsF 1080p variant, but that didn't interfere with anything.

Should not matter, both mini monitor and my screen (PVMA250 Sony) van handle that.

Thanks again for trying...

14.2.1 seems to have restored playback....

I will try better tonight...
