clip playback jerky

[rossandjet]

Hi All
I am new to the forum and having just purchased APE 11, new to that as well.
My question is this, the replay of clips are very jerky making it very difficult to check if the finished video would look good.
I have tried rendering and changing from “automatic to highest quality” to no avail.
I am sure there must be a way round this but I can't find it.
Once a video has been changed to mpeg it will play fine in WMP

Thanks

Welcome to Muvipix, Ross!

Would you mind if we moved this to our Premiere Elements 11 forum? It will more likely be noticed there.

Meantime, be sure to tell us what model of camcorder your video is coming from and what format and resolution it is.

Also post your Project Settings, as listed under the Edit menu. You ideally want your project settings to match your video specs. If this is done, you will NOT see a yellow-orange line along the top of your timeline in Expert view. Is this the case in your project.

Finally, be sure to list your operating system, your computer's processor and how much RAM you have so we can fully evaluate your situation.

Hi Steve,
Thanks for the reply
My camera is a Panasonic HDC-HS60 Full HD 1920 X 1080 AVCHD SD/HDD Hybrid
My computer is an Aspire 5536 Running Windows Vista
AMD Turion X2 Duel-Core Mobile RM-72 2.2GHz

Re your reply, there is a yellow/orange line running through the lime line about two thirds if the way up but I have no Idea how to set up the project settings to get it right.
Thanks

Your computer is a bit underpowered for AVCHD editing. But you should be able to do some basic editing if your project is set up properly.

Have you ensured that the AVCHD clip from that camcorder is the first clip on your timeline? If you do that, the program should set the project settings based on that clip.

What are the project settings, as listed under the Edit menu?

Hi Steve,
Yes, I was aware that my laptop was under powered by the number of times it stops to buffer up.
The settings are as follows;-
Under General
Playback settings,
Both edit mode and time base are blank
Clicking the playback settings shows 24pConversion width and Interlaced frame(2:3:3:2)
External device None
Aspect ratio conversion hardware (if supported)
Export: External device None
Disable video output is ticked.

Video
Frame size 1920 X 1080
Pixel aspect ratio and fields not lit.
Display format 25fps timecode
Title and action safe area are unlit
Audio
Sample rate unlit
Display format is Audio samples.
Capture
Capture format is HDV
Video render
Maximum bit depth is ticked
Previews, both File format and compression are unlit

In Expert view, do you see a yellow line above the clips on your timeline?

[rossandjet]

Steve,
Yes I do, it's about two thirds of the way up the clip line. A continuous yellow line.

Your are talking about along the top of the timeline, right? Not the yellow line that runs through the clips.

If you are seeing a yellow-orange line along the top of the timeline, above your clips, it indicates a mismatch between your video and your project settings, which can result in reduced performance.

Have you ensured that a clip from your camcorder is the very first clip on your timeline? Premiere Elements uses the first clip on the timeline to automatically set the project settings.

Also, what happens if you press Enter to render your timeline (the yellow line along the top of the timeline will turn green)? Does your playback performance improve?

[rossandjet]

Hi Steve
There is a yellow line along the top of the time line, but it is fragmented and only over the top of where I have inserted a photo and either used frame freeze or Pan and zoom to extend it's open time. These turn green when rendered.
There is also part of the same line over the clips that is green and some areas with no colour. So it could be where I have rendered some frames and not others.

Is it good policy to render each clip after it has been trimmed or should I wait until the video is finished?

It will play more smoothly if rendered, but each time you make a change to the clip, you may need to render again.
It isn't necessary to render before outputting. Rendering is only for previewing.

[Steve Grisetti]

If you are not seeing a yellow-orange line above your video clips, then your project is set up correctly -- and, for better or worse, the program is operating as efficiently as it will on your machine.
