Movie Edit Pro Mx preview window slow, when jumps to new scene

arausz wrote on 2/7/2012, 8:10 AM

In the Movie edit pro Mx , the preview window slows down, and lags, when it reaches a new scene or a fade. When I stop the preview and start it from the beginning of any scene, the program plays them well, even in HD quality. 

I cheked the questions here before, and followed them to solve the problem, but I still have this problem. I changed the resolution presets of the playback to minimum, set video playback to no catch, set the movie display to low resolution, reduced the bitmap resolution for preview, I set the preview in arrenger's video mode to default mode. It does the same lagging with all these changes like in normal mode.

The hardware I using is almost the reccomended one, except the processor. I work with windows 7, I use the Movie Edit Pro Mx v. 11.0.3.0.

Can you help me? What can be the problem?

Thank you!

arausz,

First, thanks for taking the effort to search for previous answers to similar problems.

You say "...except the processor...". What is it? The adjustments you've tried do help but can't compensate for a CPU that just isn't powerful enough. What other programs are you running at the same time as MEP? Also check with the Windows Task Manager to see what processes are using the CPU. If you click on the 'CPU' heading it will sort the list. Note it's processes, not applications that need checking -- eg a virus protection program might be doing a scan in the background though that's unlikely to be happening continuously.

Slow preview when there is a scene change without any fade or transition suggests a memory problem rather than CPU. Many modern HD video formats are very highly compressed and require reading a rather large chunk of data just to reconstruct a single frame. 

I think your version of MEP has an option to render difficult sections so that the preview of say complex transitions is smoother. It does take some time to do so but need only be done once -- until you make changes. 

Rgards,

Carl

Hi arausz

Carl has hit the nail on the head - I would just like to add -

If you are running the 32 bit version of Windows 7 then you will only have about 3.2Gb of memory available to you.  This can limit the speed of HD preview as MEP will do the rendering on the fly unless you pre-render.

Rendering on the fly requires a lot of processor time and memory hence the slowdown/judder in the playback.

Come back with more info on your computer spec.

Thank you for the answer, today I will try to run the program on a "stronger computer", and let you know the result!

I improved the performance of the computer, I changed the motherboard, now it has 16GB RAM AMD Phenom II X4 955 Processor 3.20GHz, installed a completly new system (windows 7 64), not to have any unneccesary programs in the background,  reduced again the resolution of the preview screen to the minimum possible as was recommended in the previous threads (I can barely see anything), and have the same problem as before.

When the preview reaches the beginning of a new scene, it starts to lag, even if there is no fade or transition. It needs at least 1-2 sec to play the video normally again. It is the same in HD preview and minimized low resolution review too. I try to edit mp4 files 1280x720 50frames/sec (GOPRO) videos. It seems to me that the  improvment on the perormance doesn't have any effect on the preview.

In addition, when I try to drag video files to the timeline,  the program keeps crashing. 

I don't know what is the problem, do you have any idea? 

Thank you for your time.

Did you get a proper answer to this? I have the same problem
