Ah, thanks. I still have a lot to learn about video formats!

I am trying to understand hardware acceleration now that I have a PC with an Nvidia 660ti card and the patch enables me to use it. When I go to produce, I can select hardware acceleration for MPEG-4 and AVCHD but not for MEPG-2, AVI or MOV. Is this the expected behaviour or have I got some setting wrong?
Thanks

Just installed it and it seems to have solved the problem ![]() . I am using a Geforce 660Ti with the latest driver 306.97 and I have been able to re-allow CUDA in the NVidia control panel. Not done any further testing other than check that I could preview without stuttering.

Brilliant! I've just upgraded my computer and hit exactly the same problem despite it being much more powerful than my old one. I have a Geforce 660 Ti card. I followed your advice and now it works properly. Thank you very much for posting.

Hi Will
Thanks for your reply. I think I have more or less sorted my issues which, I guess, are largely due to my inexperience in video editing.
My tests showed that the video and still pictures were fine but I got pronounced moire effects and jittery edges when I pan/zoomed the still pictures in a slide show. This was particularly bad when I used the trick of making a video clip from the slide show wizard which I did in order to be able to alter the timing of the slides. I believe the problems are due to the interlacing done for the DVD standard.
My solution is to use the best still pictures (large) that I have and to manually construct the slide show. I use modest pans and zooms and I alter the duration of the sequence by adjusting the slide durations. Then on rendering, I get pretty good results.
Thanks for the interest,
Philip

Hi Jim
Many thanks for the quick suggestion. I don't think that is the problem, though as the flicker is present when I save to folder on my hard drive.

I have read several threads on DVD quality and I am sorry to raise it again but I would like some advice on optimising it. I am editing a project with video clips and some extensive slide show regions. I tend to use motion in the slide show. If I make an AVCHD disk the results are excellent. I also want to make some ordinary DVD's recognising that they will be much lower resolution. When I do this, I get a lot of flickering artifacts along edges in the slide show - some images are worse than others. If I save the AVCHD file to disk and then convert it using ConvertXtoDVD, the resulting DVD is much better and acceptable so I think the problem is in the DVD rendering in PowerDirector. But I would prefer not to use a second program and a re-rendering. I have tried turning off all hardware acceleration and creating MPEG-2 files with a custom profile but I cannot get rid of the flickers. Is there anything else I should try?

Unfortunately, I don't think that PhotoDirector is colour managed at all. Photos do not show correctly on my monitor and I found no way to set my monitor profile. So although there are interestingadjustments possible, the program cannot be used properly by anyone needing accurate colour or using a profiled system. This is a really major shortcoming that I pointed out in the beta phase - I hope they fix it at some point.
