Is my PC responsible for jerkiness at DVinfo.net

Andrew Leigh · September 9th, 2003, 12:29 AM

Hi,

having burnt my first +R DVD I took it into work to try it out on different machines. Two did not even register there was a DVD loaded. Is this because the older players were -R?

I then stuck it into two similar laptops which recognised and played it but with very subtle jerking. The laptops have 2,4gig processors and 256Ram. Would you think that the jerking was transfered in the burning stage? My PC is only a 733MHz with 512 Ram. And I have noticed that the processor maxes out during burning and so does the ram. Bought DVD's do not jerk in my home machine but the one I burnt does.

By the way I burnt at a fixed bit rate of 8000.

Any thoughts??

Cheers
Andrew

Pc's can be responsible for Jerky palyback, however by the sounds of things your Laptop is up to spec.

Did you have any other programs playing in the back?

Also the DVD software player can also create Jerky playback, what DVD player are you using?

Power DVD seems to be the best or WinDVD however I have found Sonics Cineplayer to be far more hardware intensive.

Just a thought,

Bit rate is too high, it sounds. Commercial DVD's are hardware encoded with a bit rate of between 4 Mbps and 5 Mbps usually. Software encoders don't seem as efficient and do a similar job between 5 and 6 Mbps.

Hi Ed,
I am using Power DVD as a player.

Hi Jeff,
I will try again at the lower bit rates. Should the bit rate be set to variable or fixed.

Thanks guys
Andrew

I forgot to mention,

the video is jerky and I would have expected the audio to follow suite, but the audio is fine???

Cheers

Ed Smith · September 9th, 2003, 08:52 AM

Ummm,

Does it play fine on a settop DVD player?

Variable bitrate will decrease the file size if there is not much information in the video - i.e. Black

Constant/ fixed bitrate will be the same thoughout the video no matter how much information there is.

Cheers,

1. make sure your laptop is on AC power

2. make sure your laptop is NOT running in some power saving mode or mode where the CPU is only running as fast as is needed (Because this will garantuee DVD playback problems as I had on my DELL laptop!)

3. make sure the bitrate on your DVD's isn't too high. Higher than 8 mbps (TOTAL mbps) is in my opinion a risk.

4. try another dvd player application like WinDVD (I had problems with PowerDVD)

5. Try another DVD media preferrably DVD-R

Variable Bit Rate at Max 7000
HP DVD+R media

Works for me.

Good luck,
Arnaldo

Hi Arnaldo,

When loading the presets for the MPEG encoder I see it does load variable bit rate with 7000 ad max bit rate. I will try these presettings next.

Could someone explain this to me, a friend uses NERO 5.5 for burning DVD's. I got NERO 5.5 bundled with my CD Writer but it does not give me the option to burn DVD's. The checkbox for DVD's is there but is "grayed out". Just curious.

Cheers
Andrew

Ed Smith · September 13th, 2003, 04:22 AM

Andrew,

I believe that to be true. Bundled Nero software is basically a cut down version of the full version, and so will only really work with what it was bundled with. I believe you have to upgrade in order to benefit from DVD burning.

thanks,

Ed

Andrew Leigh · September 13th, 2003, 01:06 PM

Ok,

I loaded the preset setting for the MPEG encoder that I use as a Premiere plugin. I then encode my 54 min video (which takes 12 hours???) I then discover that the presets record the video and audio tracks seperately.

I am now left with a .m2v file which I assume is the video owing to it's size and another file, audio?, which I am unable to access. Even if I RH click it informs me that it us unable to load a certain .dll file and trashes the appication.

I can't seem to be able to get the two to work in conjunction.

Help
Andrew

Andrew Leigh · September 13th, 2003, 11:11 PM

Me again,

the two .dll files are cpuinf32 and mplvpx. A quick internet search revealed that with MyDVD these cause a problem so I downloaded the "fix" which does not fix the problem.

I then decided to encode the movie again this time keeping the audio and video together now the entire file is a problem. The preset I am using is LSX MPEG2-DVD Assets (PAL) for anyone using the Ligos MPEG plugin for premiere.

I can play all other files on MP9 except this one.

Any ideas?
Thanks
Andrew

That is quite normal to have seperate audio and video files.
You'll need to multiplex these together which any DVD
authoring application should be able to do.

Have you tried any other DVD playing software? It sounds
like you have some bogus software installations
