Video jerky when editing

[mwsing]

I often have the problem that when I am editing a video in Videostudio Pro X5 the clips often seem jerky. None of the Q and A seem to deal with this specifically

Can you please right click on one of the clips in the timeline, and copy ALL its Properties here. Then we will have some idea of what format you are talking about.

If you are editing HD video, editing will usually be rather jerky unless you create Smart Proxy files. I'm guessing that's what you are seeing. Once you generate Smart Proxy files, editing becomes very smooth.

There are two steps to generating Smart Proxy files:

1. Be sure Smart Proxy is enabled. Go to Tools > Smart Proxy Manager > Enable Smart Proxy.

2. In the Library, highlight all your video files. Do a right mouse click and click on "Create Smart Proxy File" and follow the steps -- it's not hard. It will then take some time (depending on how many clips you have and their length) for your computer to generate the Smart Proxy files. I usually let my computer sit for 30-60 minutes if I have a lot of files. If there's only three or four files, it will be done in a minute or two.

However, if you give us the information Ken asked for, we can be more sure this will fix the problem you're having.

Hi Bob: I am having the same jerky video during edit now in ProX5 after having had the following upgraded on my computer:
1. Addition 2 GB ram added, to make total of 6.
2. New blue-ray burner added
3. 4 port USB added

Before that it was running smoothly. My computer is dual core, 64 bit.

I am downloading all my raw video files to an external drive and working on the project on the external drive. I have been doing this for quite a while with no problem. In the upgrade process the external drive numbers have now been changed.

Before I read your thread I right clicked on a clip of video file on the timeline, it added two of the whole video files I'm using to the Smart Proxy folder on my C drive, not the external drive. Two of the files loaded there but the other ones did not for some reason.

So then I right clicked on the videos in this project meaning I right clicked on the thumbnails per the thread here and added them as Proxy files but I only see two of them in the Proxy manager.

I guess I have a couple of questions:
Does changing the project drive location disable proxy files?
Does ProX5 know where to find them if Proxies are on the C drive but the project is on say the F drive? I am working on external drives due to am worried about computer crashing and losing it all.

Thanks for your help.

Bob, I forgot to mention, my project is a two camera edit (thanks to your good video on it). It is a 35 min Beethoven concerto. Again, it was working fine before the upgrades and now chugs along, loads slowly and jerks during edit to the point I am unable to precisely do crossfades or any edit on it really without the jerkiness.

thanks again,
Candy

Glad to be of help. However, I don't know the answer to your question about changing the location of the project drive. That could be the problem, as I've left mine in the default location and never had any problems. I have x6 now and Smart Proxy has worked fine on the handful of projects I've done so far.

Let's hope that one of the other guys with more computer insight can help out.

Bob, thanks for responding. What I'll do is try editing and saving where Corel defaults to the way you do it.

Bob, my two camera project seems to be running fine now during edit after I "loaded" proxy files, took about 1 hr to do 5 files.

So the way the proxy files work is if you have "enable proxies" on, when you select camera files to work with, a proxy file is automatically generated? That's how it works?

And if you didn't have Proxy files turned on, they wouldn't load, thus needing to do it "manually"?

thanks,
Candy
