Ho John

Thanks for the sweetly worded response. I would suggest that most of the information you've asked for is pretty irrelevant as this problem hasn't occurred before but, if it makes you happy, here we go:

- Processor: Intel Core i5

- RAM: 32 GB

- Hard Drive: 500 GB (free space - 372 GB) with integral graphics card

- Windows 7

- Inside leg measurement: 34 inches

- Blood type: A rh neg

Anything else I can tell you? Will I get a less sarky reply now?

Love and apples

I don't think John was being sarcastic, in contrast to your subsequent reply. I think he was expressing the frustration that some of us feel when we're given so little to go on. To help other users (in this user-only forum) takes significant effort, so it's reasonable to expect that the poster takes a little too.

For example, if you'd followed the request in this sticky:
http://www.magix.info/uk/please-do-the-following-before-posting-your-question.forum.621831.html
and entered the string 'jerky' in the Search tool on the right of this page you'd have found several that might have helped isolate the cause of your problem.

Here's the main part of one from me, for convenience. It's a couple of years old but may still be helpful:

--------------------

A summary of steps you can try to fix the issue, for you and others who end up here with a search:

1. PC spec
Fairly obviously, this will affect performance. And for HD files particularly, if that's what you're working with. (If you're using a new PC, and haven't read the manual, check that there's no 'Power' setting! I've read that some, particularly laptops, let you lower the CPU performance.)

2. Monitor resolution
Press the 'Y' key to display the Program Settings window. Under the Video/Audio tab, in the Movie display section, experiment with the options. I normally use Half as you see here.

(I don't usually embed images directly, as the magix.info site displays them at such poor resolution.)

3. Other Video/Audio settings
I make no claims for my settings being optimised but they work fairly well, so examine them for any that differ from yours and experiment methodically.

4. Cache
Press the 'Y' key to display the Program Settings window. Under the Playback tab, in the Video Playback section, experiment with the options. I find that different file types need different settings. Mostly I use No Cache:

5. Audio buffer
Under that same settings tab, experiment with your entries, with mine as a starting point.

6. Fill the cache
Play the clip (or the whole timeline) once or twice to let the cache do its work.(Pretty obvious and usually done several times in frustration anyway!)

7. Codec issues
A subject in its own right, but one aspect is to experiment with MEP's Import Modules. Here's an illustration I made last year for an MEP16 user, but MEP17 and MX are identical or very similar. Experiment in particular with those I've underlined.

8. Change project settings
I've not tried this tip from Alwyn, a valued long time contributor to our old forum.

The idea is to import HD material (if that's what you're using, you haven't said!) into an HD project with the 1280x720 movie settings. Then change the File > Settings > Movie settings to SD 16x9 720x576 (480 if NTSC). Quoting Alwyn: "Surprisingly the preview still shows in HD but the transitions show in SD thereby reducing the load on the processor. When you are happy with your movie edits, just change the movie settings back to the HD res. of the original footage and export."

BTW that forum was sadly dropped by Magix but still accessible for its archives via the Search box at http://support2.magix.net/boards/magix/index.php?showforum=113

9. HD Acceleration
Press the 'Y' key to display the Program Settings window. Under the Display Options tab, in the Video Mode section, experiment with the 4 options. I normally have mine set to HW Accel as shown.
https://dl.dropbox.com/u/4019461/MX-Settings-DisplayOptions.jpg

(One exception is when I try to preview my movie in Burn mode. Then I have to switch back to the Default option and also find I need to switch Playback cache to Output and file cache. A second exception, when I again use Default, is more obscure, when I'm working with certain alpha effects.)

10. Create Frame Table
Experiment with right clicking a video object and using Create (new) frame table. But beware: this can screw up any editing you've already done on that clip.

11. System Settings
Press the 'Y' key to display the Program Settings window. Under the System tab, check your settings with mine as a starting point:
https://dl.dropbox.com/u/4019461/MX-Settings-System.jpg

12. Edit Trimmer
Try this suggestion from Peter (SceneStealer), quoted almost verbatim:
"Right click and select the 'Edit trimmer'. Click the transport control, in the trimmer window, to the far left (shaped like a floppy disc) and it will render the transition in RAM temporarily and give you smooth real time playback in the lefthand pane - albeit a little small."

Hi

Touche! - no sarcasm intended.

. . . . Intel Core i5 . . . .  which model ?  The different generations have different integrated graphics eg i5-3550 has a HD2500, an i5 4670K has a HD4600 etc

Still need the information about the export settings and also the codec you used ie did you use the Intel or MainConcept.
