Stuttering video when reviewing clip or project

[Carroll]

Same new tape as the one from my Dec 20 video (downloaded as an .avi) which, ran without problems.

I was out on Monday Jan 7/13 and shot 3 videos. After downloading I brought them into a VS folder. I played each one. The 1st two were clean and clear. The 3rd one had a section of 15-20 seconds of stuttering in the middle. I closed out the few windows on my desktop that were open and did it again. No change. Then I rebooted and shut off all the small programs that run in the background and ran it again. Same results. I then downloaded it again. Same result. Downloaded it once more and changed a setting I had missed. Same result.

I then went to WinDV and same thing with it. Closed VS out and retried with WinDV. Same result. Went back to VS and downloaded as an NTSC DVD giving me a mpg-2 file. Plays perfect.

I had said previously that I had already installed the K-Lite codec pack quite a while ago. I'm going to uninstall it and download a new one and install that and see if there is a difference.

Well I downloaded and installed the Dec 26/12 version of K-Lite Mega codec pack. BINGO!!!

One small victory anyway. I ran the one that started me on this quest and no difference. It could be that in order for the codec to have an affect on it, I may have to download it from the tape again, IF, I haven't taped over it. I shot it 14 months ago so I suspect it's gone.

Anyway, I'll post when I have news.

Well I'm back. I have 2 .avi videos that are full of stutter. They view fine on my Sony HandyCam analog but, when I get them into VS pro 4 it's just stutter after stutter. Even downloading them with WinDV it still stuttered where in the past the other ones that stuttered I downloaded again with Windv they didn't.

One of the weird things about is there are times just after it goes through a stutter period that, when I drag the the slider back and let go of it the video replays the same piece without stutter. It doesn't happen on a regular basis but it happens. After it passes through that area the regular stuttering continues.

I now seem to be back to square one.

What are your full system specs: CPU, how much hard drive space free? Have you defragged the drive lately. Your "stutter" indicates a problem with your system.

You can change the default size of the Smart Proxy files to 352 x 240 in Preferences on the Performance tab. That way even with 720x480 DV-AVI files you can create Smart Proxy files that are half that size.

I used to do that when I had Windows XP on an underpowered computer.

Even with 352x240 proxy files, effects and transitions would make playback stutter. To combat that, I would drag a transparent Tiff file to the bottom overlay track and extend it so it was about 15 seconds in length. After clicking on the tiff file and putting preview in "clip" mode, I would play it back. This has the effect of rendering the preview to RAM. The next time I played back the tiff clip, the movie played back smoothly.

Once you move the tiff clip or change it's length, the cache is cleared and the movie won't play smoothly as before. And if you extend the tiff clip too far, say to 25 seconds, then you will lose the preview that gets built up in the cache during playback once playback has passed 15 seconds, for example. The length of the tiff clip or playback has to be kept under a certain time. About 20 seconds was the limit on my machine with 352x240 proxy files. With 720x480 proxy files, about 6 seconds was the limit. Also, don't put the preview in "Project" mode as that will clear the cache.

Hi Carroll

I am still confused regarding the type of video file you are using.

Can you make a sample available for download, maybe using Media Fire.

No, I have not defragged my hard drive for sometime now.

Is below what you were asking for? If not where do I get it?

With only 17Gb free on your hard drive and not having done a defrag/cleanup of your hard drive lately, I can see easily why you are having stuttering problems.
On top of that I would think that your system is on the low end for running this software.

I did some transferring of files to my E drive so now there are 28 Gb free on C. Had started to defrag the drive but cancelled it and will set it to run when I retire for the night.

Please explain " that your system is on the low end" and what could be done to improve it other then buying a new one.

Also, when the system gets fragmented should I download the video files again?

I'm also going to check to see it the K-Lite Codec Pack has been updated since Dec/12 and if so download and install it.

Like canuck I'm surprised that you can achieve anything with your present set up, being brutally honest, your system is ready for the scrap heap. Video editing requires considerable system resources to run effectively, you have only 1.43GB ram, your system will take up most of that, leaving nothing for VS to utilize, you really need 4GB of ram, which is the max. that XP can utilize and you should have around 50GB of free space on your HD for SD editing and up to 100GB free for HD editing, not that your system could handle HD.For HD editing it is preferable that you have a min. of 6Gb of ram.

Sorry to be the bearer of bad news, but it's time for you to upgrade your PC

Robert, you're lucky that we're now civilized and don't shoot the messenger bearing bad news anymore!!

Anyway, thank you Robert. I knew that someday it was going to come down to increased Ram and maybe a video card or worse yet, an new system. I've been thinking of a new one for quite a while but, can only afford, right now, to keep patching up this old one. It's 11 yrs old and has never caused me a problem. I hate to give XP up it is so reliable like WNT4 was.

I have managed to create 26 videos, starting early last year, and put on YouTube. With the explanations and solutions offered on here, I see now that, as I downloaded more vids from my Handy Cam the HD started to fill up and it has been the last 7 or 8, starting late last year (my 1st post was Dec 09/12/), where the stuttering started. Got help here and as it turns out, temporarily, cured the problem. I Downloaded 3 videos this month and here I am.

The K-lite Mega Codec pack has been updated since my last download of it so I have downed it and installed it earlier. It's now version 9.8.0.0.

Thank you Robert. Now all I need is a sale on Ram.

When setting the proxy it says create a proxy when the video size is above *** x ***. How does the video get above that setting as I've only had proxy files when I first started using VSPro2? When I upgraded to Pro 4 I haven't saw a proxy file at any time even though enable smart proxy is checked .

By changing the proxy setting to that small does that affect the end result meaning will it come out at the 720 x 480 when I do "Share"?

So in using the transparent .tif the whole video and trimmed pieces were all worked on in clip mode, even when it came to the share step?

When I run my clips in clip mode now (described in an earlier post) only the audio works and the video doesn't move until I stop it then, it jumps to where it would have been had it been moving when I stopped it.

Hi Carroll

Hi Trevor

I apologize for not responding earlier. I missed your post.

It is a video I took of our train show and I'm trying to get it ready to embed on our club site and up to YouTube.

I download from the HandyCam as an .avi file. I work on it in .avi and in the share step I create an .mpg file for upload to YouTube. I'm unfamiliar with Media Fire. I can create a sample I think. Would it be uploaded here or in my flicker account?

I have downed it from the HandyCam in .mpg and .avi. .avi is my choice to work with so would you want just that or a piece of the .mpg also or, none of the above?

Hi Carroll

What is the make and model of your HandyCam?

Because you are able to choose Mpeg or Avi would indicate the camera being connected as an analogue connection.

Avi is just a container, there are some 800 types of avi, you have to choose the capture properties. If you get tis wrong the quality will be poor.

If you use a MiniDV type camcorder, it should be connected via Firewire, giving two capture formats to choose from DV and DVD, for DV the footage on the camera is DV-Avi, capture is a little different to analogue as you do not set the capture properties, the footage being transferred to the pc, no conversion is done, what you get is DV-Avi
For DVD you will have DVd templates to choose from.

If you can give the properties of the captured video may help.
Right click a clip in the timeline and select properties, take a screenshot create an image and post to the forum.
Do this for your Avi and Mpeg

[Carroll]

I believe this is what you are asking for.

It is a Sony HandyCam DCR-HC28. It is an analog camera using the Mini DV tapes.

My usual capture is Microsoft .avi. That's also what I do my editing in, generally. When I choose the template NTSC DVD I get the .mpg-2 file format. All the settings are set to MPG. In properties, Upper field 1st is set but when I right click for properties it says Lower field first. The video is downloaded using the fire wire cable
