Dropped Frames when Recording

  • Updated 4 months ago
I'm recording on a really high end machine and getting a lot of dropped frames. (Recording some SketchFab uploads in 3k with video quality set to High in settings.)

Also, is the frame rate encoding variable? I would prefer a forced 30 FPS or 25 FPS so it plays friendly with editing programs.

Hi Zach;

The dropped frames may not necessarily mean that the content that you are seeing is not smooth or crisp. This is because Camtasia's recorder will analyze the frames and remove duplicate frames. When you play your TREC back in Camtasia, how does the video play?

Hi Robert, this is a Snagit 2018 issue. Does this affect your answer at all? My bad for not specifying.

Being as this is in the "Desktop: Snagit (Windows)" Community, I think you did.

Hi Zach;

Ah, okay, thank you for clarifying, when the post was created there was no category assigned to is; I've moved it on over to the Snagit Windows category (though if this is for Mac, please let me know and I can correct it). While Snagit does do what it can to hit a 30 FPS framerate (assuming you have the High Quality option set in the Capture Preferences of Snagit), it records at a variable framerate. For smoother, more flexible recording capabilities we recommend using Camtasia.

Thanks much, now that I'm in the correct area, are there any other recommendations for getting consistently high framerate with SnagIt?

No worries!

What resolution are you capturing your video at? If you open the Snagit capture app then go to File - Capture Preferences - Capture, is the video quality set to "High?"

I'm capturing at 2560 x 1440 and yes, I set the video quality to High. I see that Medium Quality is 'recommended' but I'm not sure why it says that.

Hi, I would like bump this issue since it poses a pretty big issue for our company. I'm not sure what the major performance factors of screen recording in SnagIt are:

  • Screen resolution?
  • The quality setting?
  • The GPU already being in use?
  • The fact I'm using SnagIt 2018?
  • The fact I'm using Windows 10?
  • SnagIt doesn't like my fashion sense?

I've found that if you constrain snagit to a single core (since you have a high end pc this should not be an issue) this problem gets fixed on my end. Might help you. Task manager\Details\(right click)affinity. Hope this helps

Unfortunately this didn't work for me. Appreciate taking the time to help me out though :)

SnagIt is just like Camtasia,
If the screen it stagnate without any activity.It will drop a lot of frames. If there is activity, it will throttle frame rate based on that activity.

You will never get a consistent frame capture rate. Not in my experience.

Even if you record a video playing of a known and consistent frame rate. It will record at the same rate as the video at times.And other times drop frames like crazy.
I've ran many test recordings of videos playing. The longer the recording, the more likely you are to start dropping frames. The same video will produce different results when recorded more than once.No rhyme or reason for the inconsistency's. 
Any longer than a minute of capturing a video, and frames usually start dropping.

I've got a good strong computer.

 4th Generation Intel Core i7-4770 processor 3.40 GHz (8M Cache, up to 3.9 GHz)

16GB RAM Dual Channel DDR3 1600MHz - 4 DIMMs EA - -

NVIDIA GeForce GTX 660 1.5GB GDDR5 EA - -    Supporting   4 Displays

Samsung 860 EVO V-NAND 1TB SSD SATA 6Gb/s           3 EACH


Desktop recordings rarely have movement/activity to capture 100% of the time. So 30fps captures are not really on the table.
 
I don't think you'll ever get 30fps videos consistently. I've tried from time to time for years on both platforms, never got there.

I cringe when members  advice others to record a video playing in a media player.In order to edit it, when Camtasia cannot import it.
Because I know it's probably going to drop a lot of  frames.

That's just the way the recorder works, maybe it will be reinvented some day?

Heres the difference  between Camtasia and SnagIt.
Camtasia converts any video placed on the timeline to 30 or 60 fps based on project settings.
SnagIt doesn't convert anything, it simply gives you the frame rate it captures. There's no effects you can add.Titles, animations etc. Or benefits to gain by artificially increasing the frame rate.

Thanks Joe, especially for doing those tests. Yeah, in some cases I think Variable Frame Rate would be hugely advantageous.

However, I really wish that there was an option for Constant Frame Rate, and I know my PC is capable of capturing in at least 30 FPS, whatever I'm doing. It has a 4.0 GHz Xeon XPU, P4000.. there's no question it can handle it.

I've had some luck re-interpreting my footage upon import to a higher frame rate because Adobe products mis-identify variable framerate footage, but there is still quite a bit of jerky movement due to insufficient frames.
