I notice that you are using shadow files. Are you allowing all of you clips to turn green before you edit. This is very important.

Try disabling shadow files and see if it still happens. Panny TM10, GH2, GH4,

Baz, can we get the dxdiag? The instructions are at the top of the forum, constant rendering is a sign of a driver issue, but we need to know what version and build of PD you are using. HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)
Nvidia GTX 960(4GB)/16GB DDR3/
Canon Vixia HV30/HF-M40/HF-M41/HF-G20/Olympus E-PL5.
Tape capture using 6 VCR, TBC-1000, Elite BVP4+, Sony D8 camcorder with TBC.

Well that certainly gives me some comfort knowing that I am not alone!!! I am using Intel HD graphics and since your first message I have found that the Intel drivers for their HD Graphics was out of date and I have just updated. So I will inform you of the result as soon as I get a chance to find out. Bunkerbaz

Baz, do you have an Nvidia card also? HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)

No



Will email Jpg of dxdiag. Bunkerbaz

It seems that after updating the Intel HD Graphic drivers all is OK. I have only had a short trial but it seems OK.
Meanwhile what is a shadow file?
As the forum says, I am a "Newbie". Bunkerbaz

Hi Baz

What is a shadow file, you ask.

The fact that you are actually asking the question makes me wonder if they could still be a part of your problem.

When shadow files are enabled in your preferences, PowerDirector takes your original clip and creates a low res proxy file that the editor can handle more easily. This is especially useful for those people with less powerful machines, or high end users who want to work with the high bit rates of 4K. In these cases editing without shadow files would be vert difficult.

I noticed from your earlier screenshot that you have shadow files enabled. I know this because in your library room all the clips have a little green flag in the bottom left hand corner. A green flag means that a clip has been loaded into the library and is now ready to be edited with PD. The important point here is that the flag is green. When you first load your clips all the flags are yellow, which means the clip is not ready to be edited with PD. If you are using shadow files you must wait until ALL the flags are green before you begin to edit. Failing to do so can result in some very odd things happening.

The main problem with shadow files is they are very, very slow to generate, and this is why I wonder if all your clips had turned green prior to your edit. I was unable to see the colour of the flags in the clips that were below the library line.

If you feel you don't need shadow files they can be disabled in preferences / general. Untick "enable HD video processing"

I hope this pretty much covers it for you, Baz.

Robert Panny TM10, GH2, GH4,

That is very well received advice Robert. I obviously have several options in record mode and I have chosen what I thought was the best option MP4 1080/50p (PAL)
I have been using PD since PD7 and had great results but have only used digital stills. Mainly because of my Super 8 days when I would spend so much time looking through a viewfinder. Now I am using video it is a different ball game so the advice I get here is of considerable help. I will follow up your advice. Many thanks...Baz.
PS: Would it help if I installed Nvidia?
