Video Lag During Playback in Sequence Editor

Recommended Posts

I am hoping someone else has had a similar issue and has found a solution.

I purchased/built a new pc.  It is an i7 8700k with 32gb ram. It has a nVidia GTX1060 graphics card with 6gb of ram, running windows 10 with all updates installed.  When I run a sequence in sequence editor, the video lags and hitches.  I have tried uninstalling and reinstalling LOR 4.3.18 and have updated my video drivers from nVidia, with no change. I can run the same sequence on another machine with lesser specifications with no hitching.
 
Here is a link to a video to show the hitching that occurs in the sequence editor without visualizer running.  The hitching also occurs in visualizer.


I submitted a ticket to LOR, they suggested that CODECs were to blame and I might need to re-install a Windows.  Being a new computer, with little installed, I reinstalled windows an I still get the same result.

Any suggestions?

IMO it looks like something is trying to run in the background. You may just want to let your laptop run its course for a little while. New computers seem to be the worst when it comes to updating esp the antivirus garbage that comes on them.

That's what my new laptop looks like while my updates start running when I am sequencing past my bed time.

Set your auto update time to when you are not normally awake.

I'm doubtful that reinstalling Windows will do anything to fix it.   That sounds like the standard canned answer that every tech support department gives.  If anything, it is usually a driver or codec issue as mentioned, but that doesn't involve reinstalling Windows.

You’re right. Reinstalling Windows did nothing.

I would understand it being a codec if there was hitching in a video file, but this is in the sequencer window.  Could it really still be a codec?

Just to see if your video card is having issues.

I know you said its new, but that does not mean anything today.

Yank out your video card and use the one built into the motherboard. S4 runs fine with the built-in intel video.

Also make sure it's running the NVIDIA driver and not the generic Microsoft one that comes in Win10.

Thanks JR.  That’s what I thought too.  So I made sure it was done with all updates before running LOR and recording the video. Any other suggestions?  There is nothing installed except for Windows and LOR.

As JR said something in the background may be hogging CPU cycles. Check the CPU loads in task manager.

On a long shot, what format is your audio file encoded in. Try using.WAV.

CPU is at 5%. GPU is at 22%

Do you have VLC (Video media player) installed? VLC has a bunch of Codec's that come with it. I ran into this on a new pc. The Codec's provided by MS Windows didn't do the job, VLC added all the Codec's I needed, at least for Video and Audio Editing.

It's Free and a pretty good Media Player to boot.

Read about it here.  VLC Media Player
