Why is my Matinee movie lagged (glitched)

I tried every method of recoding my cinematic matinee but the final resul is lagged.

Avi, Bmp, Jpg (25fps, 720p, 1080p) …all of them have a bad result. The movie is very lagged even after compressing it in AE.

(Also, My project is located on a SSD for a faster recording)

Hi VladV,

I’ve personally not experienced this kind of behavior from Matinee on my system here at Epic or my system at home (which is not near as high end).

I have a good level to test this sort of potential lag in from a personal project where I have a library with thousands of books. In the build of my project there were no LODs setup and at one point when the matinee plays and turns to face a hallway of nothing but books it would freeze for a good 10 seconds before proceeding on with the matinee.

Even with this known LOD setup if I rendered out (which I did right before starting this post) There was no lag on that initial turn towards all the books.

I tested this with the AVI file at your settings of 25fps and 720p. The image renders are not possible for me to test though since I do not have access to AE or any software to bring the image sequence in and edit.

Can you do a couple of things to test this further to make sure it’s not a project situation here though.

Can you make a simple matinee in a template project and render a matinee to see if there is lag there as well?

If this template project is giving you an issue can you send that project to me via dropbox or equivalent link to test? This way we can start ruling out any factors that may be causing the lag to happen.

Do you have access to another computer to possibly test rendering the matinee with?

Thank you!

Hi Tim,

Thank you for your interest in this issue. Following your suggestion I exported a matinee from Realistic Rendering project and the result feels lagged, same as my project.
Here is the matinee from my project exported as jpg sequence

Here is a matinee with the same settings from realistic rendering

On this tread we used an alternative. We recorded the matinee using FRAPS (game capture video recorder fps viewer). And the result is much better.

We also tried on different PC’s with same result.

Hi Vlad,

I know this is a little delayed in a response. Have you tried rendering out at 30fps to see if you get the same results? Typical video FPS is 29.97. This may help in the stutter. A co-worker and I recently did a fairly heavy scene for a library that was rendered out at 30fps with png images and made into a video sequence in Adobe Premier. We didn’t have any stutter like you’re seeing. I can try testing our scene with 25fps and see if I get the same issue if this doesn’t work for you.

Let me know.

Thanks!

Tim

Thanks for your answer, I will try more. Currently I am using http://www.fraps.com/, but, I am fairly limited by my graphics card.

Later today, time pending, I’ll see if I can render out a sequence in my project at 25fps and see if I can get the same results. I’ll let you know how that works out. :slight_smile:
