Camtasia Latency Issue

  • Updated 6 years ago
When lots of stitches are made to video a slight but very annoying stuttering occurs during playback in edit mode which leads to various problems when editing. Before I get into details first I will identify PC specs.

My PC:

CPU: I7 4th Gen Intel 4700mq 2.4 ghz (4 cores/8 threads)
Memory: 8 Gigs of ram
OS: Windows 8.1
GPU: Nvidia GTX 860 2GB DDR5
Monitor: 3200 x 1800 resolution default
Hadrive: SSD Hybrid

Ok so lets continue to the issue of stuttering. The problem with stuttering I have is that when I listen to video in time-line I have no way of knowing how well a sentence will flow until I render out video due to the stuttering issue. Having to render a video out each time to know how well the speech flows or if a speech correction I made is accurate adds up to a lot of wasted time on client projects.

Additionally the other issue is that the play head will freeze although the video still plays smoothly this is an issue as I am not able to identify where the play head is at in relationship to the the video content being played until I pause video. Once video is paused the play head will then jump to location I stopped video at.

The last latency issue is that the animation like the fade for example will flickr as if the program is struggling to show transition. This doesn't occur right away but eventually happens after only 5 or 10 minutes of using program no matter how small or large the file size is. Also if I attempt to add transitions to videos that are 1080p the program will struggle and pause at the transition points and then resume video.

I've closely monitored my system resources and the program is not evening using 50% of cpu, memory and so on so I don't think it is a issue with lack of performance since I have a very high-end Laptop.

Any insight would be great as the reason I upgraded to new laptop was with the hopes that these problems would be resolved.

What version of Camtasia Studio are you running? There were some issues with stuttering playback of MP4 files that were addressed in the 8.4 release.

Hello there,
You can find  8.4 here.
Lots of nice additions on this one as well.

The update seems to have resolve issue with play head freezing and also the issue where audio would stutter when play head passes through stitching in timeline. 

I haven't had a chance to test stuff for animation transitions so I can't comment on it yet. However another issue I forgot to mention is that when I have a lot of stitches in timeline the arrows to press forward or backward makes timeline scrolling very very slow. I tried just grabbing the scroll bar and moving scrolling through timeline and same issue occurs.

I monitored my resources again via task manager and it runs at about 8% cpu usage, 45% memory usage and 3% disk usage so its not pushing my hardware so something else is going on. The videos I edit can get very complicated and lots of stitching is sometimes needed as much as 150+ stitches might occur in one video or much more depending on condition of audio and what has to be removed or adjusted in terms of speech spacing and so on.

I just tested the issue with creating a transition between a 1080p video and when I split the video and insert a "gradient wipe" transition the video freezes until it passes the animation and then it continues playing. 

My resources are only at 45% cpu usage and 45% memory so not pushing my hardware by any means. Also disk usage is at max 3% usage.

I am having Issues as well with 8.4 with CPU at 100% during rendering and I dont think that is a good thing. How can you make sure your CPU does not run at 100%

I tried everything I even bought new monitor to run it on only 1080p to see if that resolved problem but it still crashes randomly even though it barely uses any resources from my PC. I thought if I could run state of the art next generation games I could also run Camtasia but apparently that is not the case. I even tried importing mp4 as suggested but same problem still occurs and not stability at all. I constantly save every 3 minutes.
