Recently purchased PD11 ultra. Problems are with judder and pauses in the rendered output files.

Judder and pauses show up in the rendered (either using the Produce features to make files, or using the Create Disc feature to make a blu-ray BDMV structure, .m2ts files, set for 1440 x 1080i, 16:9). These judders and pauses are coincident with the clips in the project. In other words, when a new clip comes along in the timeline, there is a pause in the rendered output, and often times a noticeable amount of judder. Both of these effects occur at the start of each new clip, then the stream proceeds satisfactorily. The pause is about 1-s plus-or-minus a little, and highly noticeable.

There is some variation in judder when using the Produce Feature corresponding to whether the output is .m2ts, mp4, or the mpeg-2 mpg formats. Moreover, I tried the AVC format at different bit rats and noticed judder and pausing were in there too.

Input files: HDV, .m2t format captured using HDV split. 1440 x 1080i, anamorphic, 25 Mbps stream rate. (they all play fine on my PS3, sony TV, and on this computer using Nero Showtime. There is no pausing or judder when playing these .m2t files)

I've read that others have suggested combinations of not using HW accelerate, turn off SVRT, etc. I've tried them all--at least I think I have, and the problems remain.

I've installed the recent service pack for PD11 which came out the end of Nov. 2012. Nothing.

Yes my computer is old, 3 GHz P4, hyper-threading, Win XP sp 3, video card is Nvidia GT240 with latest drivers, etc. Looking to build a new one, but not right now. Seems to me this old machine ought to render as well as a new one, but will take longer. That's okay for now.

I'm new to PD. I've been using Pinnacle Studio since version 8, and got to 14 before giving up and going back to 12. The frustration level was pretty high. Studio's workflow for HDV (.m2t) files is too painful to continue. I like PD11, it reads m2t files directly, and looks a lot like Studio, so the learning curve is short, but it needs to properly render a project.

Any suggestions on how to get it to work?

Chris1919 ,

The good news is that PD is better than your previous app. The bad news is that like all it's HD editor cousins it's CPU cycle/memory/hard drive hungry. A real challange for your PC.

Please post your DXdiag file (see top of this forum on how) and let's see if any of us can help you to determine the possibilities. Win 10, i7

HDedit,

Many thanks for taking a look at this. I've included the DXDiag file.

Chris1919 ,

Are you ready for a PC funeral ?

If you want to do HD stuff you'll have to read the following at the funeral :

It's a shock for any decent PC over 3 years old. It's too soon to go, no ? Win 10, i7

HDedit,

Thanks for the feedback.

I have a friend with a better computer: i5, Win 7 64-bit, runs fast.

Downloaded and installed PDR11 Ultra trial version on that machine.
Now, using PDR11 (x64 trial) I randomly picked six of my m2t clips and made a project which runs about a minute and a half.

First, used the "produce" functions and had it render three files: mpeg-2, AVC, and mpeg-4 at comparable bit rates and screen resolution to the source formats being 25 Mbps and 1440 by 1080i.

Second, I had it render the output for a Blu-ray disc, type mpeg-2, BDMV, in which it created the source files and stream file, a type m2ts mpeg-2 transport stream

Results:
In each case, the pauses are still there. In one of the video files there is noticeable judder too. These pauses in the rendered video files coincide with the start of each clip in the timeline.

The source .m2t files play perfectly, as they should on my pc, PS3 and sony tv. They are not the problem.

I've tried PDR11 ultra on two computers, with two different OSs, one XP sp3, and the other Win 7 Pro (or equiv), and the results are the same--pauses and judder showing up in the rendered video files.

Conclusion:
PDR11 ultra does not properly render m2t files. It seems likely it works properly with other types of files, or there would be no sales, and no happy happy happy customers. So, for me, not a good fit.

Any suggestions on NLEs that properly create Blu-rays from m2t files?

thanks,

I've used m2t (avchd) files extensively with PD8, 9 10, and now 11 with minimal issues.

Perhaps it's time for you to post a short (1 minute) video sample file for us to look at.

I have the same problem. When the AVCHD file is previewed from the media library playback is perfect. However, when the AVCHD file is placed in the timeline and then previewed it is jumpy, skips,etc. I have used PD9 with no problems and used the same files on the same computer.

Derek,

Yes. That will happen if your graphics card is not able to process the video fast enough. It does not mean that the rendered (final) output will be jerky when viewed.

A simple fix : when a clip is placed on the timeline, below the preview window is a square button called "set preview quality". Lowering the previewed display resolution (this does not affect the rendering) will make it easier for the graphics card to handle and thereby giving you a smoother playback. Win 10, i7

had the same problem and basically was told my system was not good enough to cope with the files, including .mov files.
Have upgraded to an Intel i7, 3.2 6 core unlocked processor. 64GB ram, ssd 128gb cache on a 300gb Velociraptor and using a Zotan NVidia 680 4gb graphics card. Have 32gb ram as windows cache - and I still have the same problem!!!!!

Its not hardware - its the software, it just has to be!

The rendering of 2 layer videos and editing of same takes minutes now - it took hours on my last machine.

As soon as you layer tracks and music (not .mov files) is gets jerky! Impossible to sync and its frustrating.

Anyone out there with an answer? Thanks, George

George, see the answer in your other post/thread. Please don't ask the same question in several places (actually it is better if you start your own thread) because it confuses poor old people like me.

Thank you, Happy Holidays !

Georgemon,

As I stated in my post above, even a fast PC will demonstrate jitter on the PREVIEW window. It's simply because of the amount of number crunching going on in PD as it attempts to display the actual video WITH all effects that you selected applied. Since the preview window is small anyway it is best to select a low resolution preview as it has no effect on the final render. Win 10, i7
