You know, that for video editing, computer power is evident.
What you can try:
Try do do as less editing /color changing, speed change, all things in PiP Designer, PowerTools and clip effects as possible. Then you can try the SVRT rendering. With that, PowerDirector can just copy the unchanged parts of the video to the target film. That is supermuch faster than rendering. But even if SVRT does not work: The most rendering time is needed for clip changes, like color, speed or effects. The most bad thing is to use color presets. They can slow down rendering time significantly.
Rendering in parts may help, because you can use SVRT for the parts, but time summed up for the parts will be at least the same as if the project was rendered as a whole.
I don't know, why hardware acceleration is sometimes on and sometimes off. Hardware acceleration causes many problems, so maybe it's better to turn it off. But try, depending on your hardware, rendering can be significantly faster.
And ask your computer: Video rendering takes a lot of processor power. So maybe the processor gets too hot and is throtteling down? Then rendering in parts would be the best idea.

4GB of RAM is below minimum spec really but if you have no option but to try then I would agree with Hatti that overheating is probably the trouble. I resolved a similar problem some years ago by limiting CPU useage to 90% (you can set it in Windows Power Management settings). Make sure the laptop cooling fan is working efficiently and is clean. If possible leave a small extra fan running playing onto the laptop and lift the laptop up off the surface it is standing on to make sure that air flow around it is unrestricted.

Your computer will probably be paging out to disk due to lack of RAM. Make sure you have plenty of free space and also make sure that your HD is not fragmented.

Hi,

The key to comfortable editing on a laptop is exactly as you suggest - split your project into smaller sub-projects.
The beauty of getting SVRT to work means that, once each section is encoded (which it would have to be anyway), then the final full render takes far fewer resources for a much shorter time.
Points to note:

• Sub-projects can be long or short, perhaps determined by context, but allow for the final joining process - otherwise any transitions will eat into the finished clip.


• Audio joining can be an issue, but again, careful editing and selection of section start and finish points makes it easier.


• Editing a small sub-project for a minor glitch is then so much easier than having a massive and complex timeline to handle.


• Assembling your project in sections also allows choices and decisions as you go along, because it is so much easier to render and review so that you can get the flow and feel right.

Personally, having travelled extensively with my trusty i5 laptop (now several years old) for several months at a time - I have got into the habit, so even on my desktop I prefer to do that. I've just done a 5 min video - mainly slideshow combinations for an art exhibition - but it has 6 sections, each independently edited and produced with 3 audio beds running through and some custom titles/video transitions. It could easily be done in one, but I just find it easier to do in sections.

All depends on getting SVRT to work effectively for you!!!

Try it and see, it really can take the strain out of things.

Thanks for the information, all.

Laptop crashed again last night - after rendering all day and getting to about 90% done!

So going to try splitting the project up and using SVRT.

Time to render in desktop, more cpu cores is better, ssd drive, 8gb ram, decent video card and you will be 😀.

No matter what software you will use to render, laptop rendering is slow as turtle compared to desktop. AMD FX8300 8core 3.3Ghz,16GbDDR3

If I had a desktop, or could afford to purchase one, then that is indeed what I would do.

What about the image quality,the same as with jpg (compression) ....bad,or does it not matter?

Hi,

SVRT acts to render only those portions of a project that have been modified. Other "unmodified" portions are not rendered. This has 2 implications:

• It is much quicker


• It does not alter the source material

CL FAQ here states the parameters necessary for SVRT to work : https://www.cyberlink.com/support/product-faq-content.do?id=7271&prodId=4&prodVerId=-1&CategoryId=-1&keyword=SVRT

PDR17 help says :
"Intelligent SVRT* (Smart Video Rendering Technology) is a proprietary rendering technology from CyberLink that assists in the output of your video productions by suggesting which video profile you should use.
Note: * optional feature in CyberLink PowerDirector. Check the version table on our web site for detailed versioning information.
Based on the format of original video clips in your project, what portions of the clips were modified (and therefore require rendering during production), and which portions of them were not changed (and thus can be skipped over during the rendering process), Intelligent SVRT suggests the video profile that will result in the best output quality possible, and save you the most time during production."

Hope that helps
