Why is my mp4-export jumpy on other PCs?

Hi,

I'm using MEP18 and made a timelapse movie from many still frames in combination with some HD video files (1920x1080@25fps). For exporting I use these mp4 settings:

1920x1080
16:9
25fps
audio:41khz
bitrate: 8000kbits

When I play the movie file on my pc all is fine, but when I copy it to my laptop (2GB RAM) it is all jumpy and/or the picture can't keep up with the music. Same with another laptop.

I tried to export with 4000kbits but then the quality of the picture is quite terrible.
I also exported in 1280x720 and still face the same problem.

Exporting to wmv made the picture terrible.

Does any of you have a hint what I'm doing wrong and how I could fix this?

Thanks, I'm rather desperate by now...

With 2GB of ram on your laptop, I am not surprised that the laptop cannot play the file properly if the laptop only has 2 GB of ram it likely also has a very slow CPU. Your export at HD1 or HD2 is likely much more than the laptop can handle. If you want it to play on your laptop, try exporting to "DVD" quality if you want to use MPEG-4 and see if that works. If that does not work, you are going to need to export at "Web" quality and use "Windows Media video" as the format, that format should play on pretty much any computer. Will you loose video quality, yes, but if you want to play it on that computer, that is what you need to do.

Good Luck

Hi gandjcarr,

thanks for your answer and explanations. This makes sense. I tried using 1024x576 with 4000kbit and that version worked just fine. Then I used 720p with 6000kbit and I was also happy with the quality.
