Problem rendering - getting worried

Hello,

My problem was asked in this post:

http://phpbb.ulead.com.tw/EN/viewtopic.php?t=19654

Basically I am making a project that will in total be about 25 minutes. It is five songs with various video clips and still photos. I have completed several of the songs and rendered them to MPEG files to eventually burn to a DVD and have had minimal problems.

Yesterday I was working on the fourth installment and when I went to render it I did everything the exact same as I had for the first three installments but something strange started happening. The most noticeable thing was that the rendering process began by rendering the first 10% while showing complete blackness in the preview pane (my clip is 4 minutes and has 3 seconds of black before the first video clip).

Eventually rendering would hit 99% at which point VS10+ would become "not responding" and I would have to close it with alt-ctrl-delete. The "rendered" portion of the project which was completed was about two minutes of the four minutes total and there was no sound.

Then when the video would hit certain points, it would seem to freeze for a moment and then literately leap ahead without the image in the preview pane moving (for example it would render from 20% to 35% in about two seconds).

I have tried the following:
-Gone back to an earlier project that rendered perfectly and tried to re-render it and -lo and behold- it now has the same rendering problems as my current project.
-Did a disk defrag and disk clean-up on all three of my harddrives. I have VS10+ on my C drive and I use a D and E drive for exclusive video and photo storage.
-Used the control panel and original CDRom to "repair" VS10+.

Nothing has worked so far.

This is especially irritating and worrisome because this is a video that will be shown at a graduation with 250 people on this Thursday so I need to solve the problem ASAP.

I did discover that when I imported all the miniDV footage for this project it somehow got captured as MPEG2 (not sure if it is the camera that does this or VS10+?) But I don't think that this is the root of my current project since I did the first three installments (plus other projects) which were fairly elaborate and they rendered fine.

Should I try and do something dramatic like system restore? What could possibly have happened in the last 24 hours that is now giving me such big problems?

Help me Obi-won, you're my only hope..

Can you recapture the clip as an AVI?

I don't know, I'm borrowing this camera from someone and don't know if it's the camera that is set to record in AVI vs MPG or VS10+?

The biggest problem is that its about 40 or 50 small video clips comiled from 10 hours of DV taping, so in order to recapture in AVI I would have to capture about 6 hours worth of DV again into VS 10...

Worst case scenerio do you think I should try and download the trial version of Mediastudio 8 and load my project into that and see if it works? Is VS10 VSP files campatable with MS8?

Thanks,

Mike

Has anything at all changed on your system between the working installments and the non-working installment? i.e. did you load new software? did somebody else use the computer and "do something"?

Logic would argue that if the previous installments nolonger work then something about the environment i.e. system or VS 10 has changed rather than the content of the last installment causing the problem (in VS 8 and VS 9 sometimes current content and how it was arranged caused a problem - but only with that project, not previous projects).

Given your timeline my suggestion would be:

1. try MSP 8 trial (not sure whether it imports VS 10 projects though)

2. try a system restore

3. (re)format your system disk and load the OS from scratch then VS 10.

(2) might be quicker than (1) depending on your download speed. But both a reasonably quick to try.

The larger the hammer the better chance of getting around the problem - so my personal preference is (3)

I use disk imaging software (Norton Ghost or Image for Windows) to maintain snapshots of my system disk - if I get unusual problems I just restore the system disk from my last snapshot. An ideal way to keep a known good and working baseline when problems like this show up! So this is what I would recommend for future - once you are over the graduation thing at least

What about transfer the files to another computer? (this may be harder than option (3) though

).

MiniDV tapes contain video in DV format. If you capture to AVI/DV, the DV data is not altered. If you capture to MPEG, it gets encoded by Video Studio on the fly.

I've sometimes had similar problems (and other weird problems) when working with MPEGs.*

I believe the most direct solution is to re-capture to AVI/DV. (As a quick-check, the file size of your DV files after capture should be 13 GB per hour.) There may be work-arounds and fixes, but you could easily waste more than 6-10 hours messing around, and still have problems!

You could try saving the individual MPEG files in AVI/DV format. Then, do all of your editing & splicing in DV, and let Video Studio convert it back to MPEG when you make the DVD. But, you might notice some quality loss due to two MPEG encode cycles, and if it doesn't work you'd be wasting valuable time.

* Some Ulead users don't have these problems, but I got frustrated and gave-up on editing MPEGs with Ulead. I now use a special-purpose MPEG editor. (I still use Ulead to author and the burn the DVD.)

Hi Mike,

good idea but.... Unfortunately, the support for VSP files was added to MSP 8 with SP1, service packs do not work with trial versions, sorry.
