Motion Artifacts in Slidshow

I am creating my first slideshow using the slideshow option on PD12. I choose a motion template that produces a very slow pan and/or zoom on each picture. I burned it to a DVD as well as produced an mp4. The mp4 looks fine, however there are annoying artifacts during the pan or zoom when I view the DVD on either my TV or PC. To burn I used the DVD-Video format, widescreen 16:9, MPEG-2 and HQ-Best Quality.

I am hoping someone will be able to give me some suggestions.

Thanks Mike

Motion artifacts often show up in interlaced video with fast motion. It is made worse by the reduction of the video quality going from a High definition video down to a standard definition DVD.

You can create a AVCHD or BluRay that is High Definition.
Fast motion artifacts are less visible in HD.

Thanks Carl for the quick reply. However last night I tried creating a DVD using the AVCHD format. When I tried playing the DVD in my PC, PowertoGo opened with an error saying "invalid format" and it would not play. Also you stated "interlaced video with fast motion" ...this is a slide show with very slow moving pans and zooms. I also assume that you would have to use speacial BluRay DVDs to record in the BluRay format. Mike

PowertoGo is not a player, it is a disk burning program.

Yes, it takes a BluRay player or Codec on your computer to play a AVCHD or Bluray Folder.

The free player VLC will play a Bluray or AVCHD folder.

The AVCHD folder contains a BDMV folder that has sub-folders. The video is in the sub-folder 'Stream'.

Hi Mike -

I've had the same motion artifacts you're referring to, even though motion in preview (similar slow pans and zooms) was as smooth as silk.

Only this morning, I produced a motion type slideshow & every now & again the produced video - 1920x1080 AVC H.264 @ 16MBps - would have a little spasm. Producing with hardware acceleration turned off resolved that.

Oh - maybe you're only talking about the disc you burnt??? or were the artifacts present in the produced file?

If you burnt an AVCHD DVD it will play in a BR player, compatible DVD player or Play Station. I have no idea why it would have opened in Power2Go.

Cheers - Tony

Tony - Outputing to AVCHD solved the motion artifacts issue. I also created an MP4 and that worked fine as well. Now if I can only figure out how to manually create a slide show with the pans and zooms built in. I don't see how to do this w/o using the slideshow creator and choosing the motion template. Mike

Hi Navillus2 -

Manually creating a motion slideshow can be achieved using Magic Motion or PiP Designer, MM providing the simplest method.

You can use the default motion templates (which typically have excessive motion in my view) or keyframe your own. The "Apply to All" feature can save a bit of time. Unfortunately, the Copy/Paste Keyframe Atrributes doesn't apply to Magic Motion, even though motion paths in PiP Designer can easily be replicated.

Cheers - Tony
