Stuttering video when reviewing clip or project

[Carroll]

Finally, after waiting out a 3 day storm, I got out today to shoot the train. When viewing the video on the cameras view screen it was without the stutters. I downloaded it and when viewed in the VS edit window it stuttered away. I then viewed it in WMPlayer and Media player Classic and, it stuttered so bad, that the player couldn't handle the amount of stuttering and just stopped playing it. At times if I drug the scrubber button back on all three the stuttering was cut by about 3/4 but, never all went away. This file had a .avi extension (668mb)

So, I thought I'd try it again and change a setting. I downloaded it again and before downloading, under properties, I changed the box for "Edit file format" from .avi to .mpg. Downloaded it and viewed it through the 3 programs I used with the first download. Wasn't a stutter to be found. This file had a .mpg extension (238mb).

So, I don't really know what this all means. My first 17 videos were downloaded as .avi files and edited in same. The last 4 have all been .avi files but, with the stuttering problem when viewing and editing them and it gets rendered also.

Carroll -- you talk about a video file of 668 MB. But how long exactly is that clip? DV/AVI takes up a lot of space -- about 13 GB per hour of video.

Hi Carroll

Can you explain exactly how you are connecting the camera to the pc.
Then in the capture screen you should be given a few Format options, you should be choosing DV.
The option for AVI should not be there, if it is then the camera is not a DV type or not connected via firewire.
Reading between the lines seems to indicate an analogue capture connection?
I may be completely wrong of course, but something is strange?

If you are able to select AVI then there is something wrong. (i am referring to the capture screen)
Also I do not think Mpeg is available it should be DVD?

Yes after capturing to DV the file extension will be Avi.

I realise that you may have given these details in a previous post but can you please confirm and provide details of your camera and also that you are indeed connecting via firewire.

Hi Ken

The DV/AVI video is 3min 30sec long.

Hi Trevor

I connect via firewire. The choosing of AVI or MPG is under properties where there is a box which asks whether I want to edit it in mpg or the avi format. I have normally left it in avi but, I changed it to mpg before I downloaded it the second time and ended up with an mpg file extension.

I have set up for another download and here are the readings(??) under the Capture options panel as they appear after the first time I click the capture video button and VS reads the camera settings and displays them, unaltered by me.

Ok. I think I may have alluded at the beginning of this saga that the problem could be the tape but it could also be another physical problem associated either with your firewire cable or card or, worse, with your firewire connection on the camcorder. (And if I didn't make such an allusion, I should have!)

The easiest to test would be the cable -- so do you have a second firewire cable or can you borrow one? How does that work? If there is no stuttering, then throw away the original cable.

Next easiest to test would be the card. Do you know anyone nearby who has a firewire connection on their computer? If so, can you connect your camcorder to their computer and test the DV capture? If there is no stuttering, then that would suggest that either your own firewire card has come loose a little in the motherboard or has developed a fault. Luckily these days firewire cards are cheap and easy enough to replace yourself if you know the insides of your computer. If not, then I wouldn't imagine a computer technician would charge too much to replace it.

If all that fails, or if your friend's computer also captures stuttering video, then I would have to conclude that the camcorder itself is at fault. That could be too costly to repair and a new camcorder could be necessary.

I bet you don't get asked to play Santa Claus, huh Ken?

The only thing discussed was the possibility it was in the continued use of the tapes. My next door neighbour has a camcorder with a hard drive but I checked and their media is transferred through either the pict bridge or directly from the camera using a USB cable that has the wrong fittings on both ends. I'll ask my group if any of them have an extra one first that I could use to see if the problem clears up. No one else I know, at least close at hand, use a Firewire cable so, if I strike out with my groups, I'll go in town tomorrow to see if I can find a new cable.

I can check the Firewire card as I've got to "open er up" to add a 3rd hard drive for storage, which will happen tonight. I'm assuming too that, if the card is corrupt, it won't be lit up or have a flashing sign telling me it is either.

[Ken Berry]

I'm not sure whether there is any light on a firewire card ... not that I recall. Just gently press on it to ensure it is seated firmly in the motherboard. I on ce had one which had somehow or other got just a tiny bit loose. Another time, when I was having trouble, I took it out, cleaned it off (computer dust!) and put it into another slot, and it worked fine thereafter. If you don't have another free slot, you might consider swapping around other cards.

I have also just gone back over this thread. Did you actually download and try WinDV? I can't find any indication whether you did so or not. But if it too produces stuttering captured video, then I would conclude most definitely that you have a hardware problem, rather than a software one.

[Carroll]

Ken. Before we go any farther my firewire comment on the card was an obviously unclear attempt at humour which referred to the lack of any type of visual evidence the card is corrupt as was my Santa Clause comment that was based on all the bad news you were giving me on what could be wrong.

Now, I have downloaded the WinDV and have launched it. However, in the Video source box. I can't find anyway to point it to my camera which is on and plugged in. "Microsoft DV Camera and VCR" shows in the box now and when I click the search button at the end of the box there are no options to find another source.

Carroll

[Ken Berry]

What other source are you looking for? I thought you were trying to capture from your DV Camera... (which is a "Microsoft DV" camera -- the DV codec being a Microsoft one...)

Never using it before I guess I assumed to much. I was looking for it to identify the Sony Camera as the source similar to what VS does plus after waiting several minutes for capturing to begin and nothing happening I finally figured out that I have to start the video on the camera before WinDV can capture it unlike VS which does it on it's own.

Anyway, the stuttering is still there in the same places as the original avi download. The second download in mpg runs without a blip.

Hi Carroll

Something is very strange, something we are missing.

You say the second capture to Mpg plays ok, yet Win DV cannot capture to mpeg.

Video studio can but via firewire you should see two Format options, DV and DVD.
DVD will capture to Mpeg2 type video

If the capture is ok using DVD then it would indicate that the camera and tape is ok, if it were the tape you would get problems choose what format you used, along with dropped possible Frames?

If that is the case then I would think you have a Codec issue regarding DV-Avi? and I do not know how the fix that.

Corel do recommend installing the Codec Pack called K-Lite, relating to HD problems.
I did install this and it seems to check the pc for broken codecs and seems to fix them. Not that I noticed any difference on my pc.

So two options
1 / capture to DVD format use DVD AC3 GQ 16:9
2 / install K-lite to see if it cures the stuttering

Corel info on K-Lite

Ken. Going back to my Fri Dec 21, 2012 10:33 pm post

When I downloaded with WinDV I said the stuttering was still there. I ran the download in MPClassic and WMPlayer to see if the stutter was there. I also ran it in VS however, I don't believe I ran that particular download in VideoStudio until just a few minutes ago, with no stuttering.Shortly before that I remembered that I had got burnt on this in the past when working with 2 folders with split scenes in both and some of those scenes were from the same tape in the same time line but, I had shot 2 trains passing and wanted to make a tape of each hence the split scenes. There I found that if there's another file in the timeline that's the one that plays not the similar one in the other folder.

I believe what happened is I created a separate folder in VS for the WinDV one and added it to the folder using the add media link. I then opened the folder and the VS view screen blinked meaning it was on the screen and I pushed play and it still jumped. I then clicked the first folder then, the new one and the first file was still in the time line even though I opened the new folder. When I dragged the WinDV capture to the time line the VS captured one disappeared replaced with the new one. The WinDV one played as did the mpg with out a blip.

Trevor

The second capture was to mpg. The WinDV to avi was the third capture.

I have had the K-Lite codec pack installed for a while now. I was able to go in and disarm the H264 ACV/DXVA codec. It is the one that there is a conflict with in playing some .avi files and it produces stuttering however, there was no effect when playing the clips again in the players.

I do have the choice in format of DV or DVD when VS is in the capture mode. I had to have clicked DVD to get that mpg version and didn't remember it. I don't see anywhere where I can get a capture format of - DVD AC3 GQ 16:9.

Hi Carroll

DVD capture templates

After setting DVD from the capture window, choose the Options cogwheel, the video Properties show a templates tab.
The DVD AC3 GQ 16:9 option should produce a full size Mpeg
Sorry if that is not full details, I don’t have the camera connected so it from memory and the grey matter at the moment is not all that great, so the wife keeps saying.

Seasons greetings

Hi Trevor

Well as long as you keep saying "Yes Dear" it'll make her happy whether she's right or wrong. Incidentally, you're lucky to have a wife to tell you that too, believe me.

Anyway, I found that template when I hooked up the camera and set it up however, my camera is set to 4:3. We went through that in another thread a while back I believe and I did try it on a couple of trains but, it just didn't look right.

I guess I'll leave this alone for a while. Maybe this WinDV will temporarily get me through. Corel is trying hard to get me to upgrade VS with all the deals they keep sending me. Maybe the Fat guy will drop some money off on his pass through (maybe I should stop eating his cookies now).

Thank you to you and Ken for tolerating me and my problems. I finally figured out how the scissors work. Take care and you and your families have a Merry Christmas, Happy Hanukah, Happy Holidays and be safe.
