E8.11 WG and multicam (slow-down)

[Marc44]

I started a multicam project with E8.10 WG (proc 2600K/Raid0) and, now, I edit the same project on a platform skylake (6700K/SSD) and Edius 8.11 WG.
In multicam configuration the TL has a slow-down at every cut , 1 frame before the cut and the sound hiccups during this frame.
In standard configuration, it's OK.
I verified all parameters, excluded all HDD/SSD for video from AV Eset, proxy out, ... I don't find the reason.
The SSD/HDD seem fine.
No problem on my old PC with the same project (2600K), but it was on Edius 8.10 WG.
Any idea ?

I'm not seeing that with Edius 8.11 WG on Windows 10 with a 4790k.

I install 8.10 instead of 8.11 and the problem is still there.
On the old proc 2600K, I don't see that either.
Maybe a real-time bug.
From Edius settings?
From W7?
From hardware?
I test Neat video : no real time at all.
Probably normal, but not sure.

Problem found, on the Graphic card side.
If I connect the 2nd monitor on the GTX970, it's just fine, no hiccup.
If I connect the 2nd monitor on the Intel GC, play isn't smooth at every cut, in multicam mode.
But, in this config, I get the Quick sync and I can play, in RT, 4 layers with PIP in UHD project.
Without QS, only 3 layers.

In pratice, it sounds not very easy ...

I have just loaded EDIUS 8 WG today and have the same problem. Moment of hesitation at each cut point when in multicam mode. I run only off the onboard Intel graphics and with EDIUS 7 ( on the same PC ) with the same project at the same point there is no problems. As far as I can tell I have EDIUS 8 set up exactly like EDIUS 7. So I am either missing some setting or EDIUS 8 has this problem. Latest version of EDIUS8WG downloaded today. EDIUS 7.51

Big improvement in that I can now multicam 3 tracks of AVCHD and 1 track of UHD60P in a 1920x1080 project exactly what I want to do. But without the hesitation!!! Must be some setting I am missing. Filters are off both are set up with no dropped frames same buffers etc. However monitoring with MooO the CPU seems to stay pretty stable at about 40%with EDIUS 8 and peaks at 90% at these clip cut points for EDIUS 7. I realize that the GPU is used in EDIUS 8 though may be the difference.

EDIT: Is EDIUS 8 WG expecting to run under WIN10 ?

[antonsvideo]

8 WG is suitable for Win7, 8 or 10

since you have onboard graphics, you will have the option to enable or disable hardware acceleration of AVCHD files in system settings, importer/exporter AVCHD

if enabled, disable and test
if disabled, enable and test

[Ron Evans]

Yes with it turned off it is better but still just the slightest of glitch and clearly not as smooth as EDIUS 7.51. Guess I will wait and see what EDIUS 8.2 is like as I would really like the UHD in multicam.

Ron Evans

[antonsvideo]

it could be caused by the version of the onboard graphics driver

I am using a GTX-980 and don't have onboard graphics and don't experience the hesitation

maybe 8.2 will take care of your issue

[Ron Evans]

I have the latest driver so will wait and see if EDIUS 8.2 improves the situation. Until then EDIUS 7.5 works fine. I have some shows coming up later in May that benefit from the FDR-AX1 UHD60P and it would be nice to use EDIUS 8 for those and although the hesitation is annoying it may work for those few shows. The issue is only in multicam mode so just may mean I watch in standard mode a little more to confirm the edit.

Ron Evans

[antonsvideo]

can you confirm that use filters while in multicam is disabled?

[Ron Evans]

Yes filters are off in multicam for both EDIUS 7.5 ( my normally way of editing ) and EDIUS 8 WG. I have EDIUS 8WG on my laptop but have n ot tried multicm on it. Will do this morning and report back in a couple of hours.

Ron Evans

[Ron Evans]

The laptop has the same issue. Just a little hesitation at each clip change. My laptop is a Dell with i7 running WIN10.

Ron Evans

[antonsvideo]

in that case, wait and see what 8.2 brings, or use 7.52

[Ron Evans]

in that case, wait and see what 8.2 brings, or use 7.52

Yes will do. Just stange that none noticed this before since I thought that one of the advantages of EDIUS 8 was its use of the intel gpu especially for multicam. With further testing it does appear to be a h264 issue as HQX or ProRes files do not experience this problem as far as I can tell. Will do some more testing. I am staying with 7.51 as there doesn't appear to be anything in 7.52 that would affect what I do.

I am using Sony XDCAM MXF files and also don't suffer this issue
