Waiting for shadow files to finish being created has long been the the recommended approach whenever they're used. With a more powerful machine (see my system specs below), H.264 and H.265 4K 60p clips can be edited directly without shadow files, but it might struggle with ones encoded with VP9, especially if they're 60p.
There is also another option, which is to use an intermediate codec like MagicYUV to decompress high resolution/non-hardware-decoding-supported clips which makes it very easy for PD to work with them in real time. The downside is that the file size is many times bigger than the encoded original clip, but if you have a large SSD everything will run much smoother.
Converting to MagicYUV using VirtualDub2 is also much faster than waiting for shadow files. My system can process this VP9 4K 30p clip at 32 fps, meaning it takes about the same time to convert the clip as it would to play it back:
Here is the comparison of original and converted file sizes. You can really see how effective VP9 is at compressing tons of video detail into a very small file size!
First of all thanks for having the time to read my posting and answering.
Thanks for the advice you've put through your reply, did not know magic yuv neither mediainfo (which helps a lot for us to see whats beneath the vids), but in my pc extremely painfull also. just a simple i7 6700 and a Quadro P400.
I'm just an amateur doing my kids holidays and less much, that first shot of youtube video was just an example.
Most of all I use is h264 which is the codec of my cameras.
I was in doubt whether it was some misconfiguration on my PC !
But you have answered it all my doubts ! Thanks !
- "Waiting for shadow files to finish being created has long been the the recommended approach whenever they're used."
I think that Cyberlink PD should be using GPU assisted to create the shadow files, which by the way they aren't and it is such an obvious feature that I don't imagine why it is not there !
Is there a way to make the "shadow files" in vidcoder (which uses GPU assisted) and put them in the right folder ?
Then theres no need to left the PC hours downscaling the vids ?
Kind regards

Noticed in your screenshot that you could be using a uhd video downloaded from YouTube in the VP9 format. Do not know if you have shadow files enabled which can help or if your preview resolution is set to high which can also help. Do not believe that the VP9 codec is supported in PD16 so shadow files is a must. PD17 has the VP9 support.
Hi,
Thanks a lot for replying, it did a little help, but I noticed something wrong again.
1) Added shadow files at 720 resolution
2) But still PD when downscaling the "shadow files" is way too SLOW because it is only using CPU !
3) For example when I use vidcoder to downscale some vid it uses both CPU and GPU thus way faster
4) But when shadow files are made (Albeit being a extremely slow process) PD multi trim works great !
Botton line if you use PD to edit 4k vids, you must use shadow files, but it is better to let PD
doing the shadow files during the night !!!!
Too slow process due to lack of optimization.
Or is someting wrong with my config ?
Thanks for reading
Kind regards

Hi all,
PD was very slow on my i7-6700, so I've bought a Quadro P400, and PD and Quadro simply are made to be together, a match I must say !
Everything is awesome now, except !!
One thing remains slow: Multi trim.
1) From previewing the footage
2) to the buttons frame by frame.
Albeit not on full power usage
CPU ~30%
GPU ~1%
SSDs ~1%
Painfully slow, really!!
Any one can help? does any one found a solution or is this PD problem ?
Thanks in advance for reading.
Kind regards.

Hello
In Powerdirector 16,
How can I trim 0,2 seconds on the beginning and 0,2 seconds in the end of EVERY clip in the project ?,
without doing it clip by clip individualy.
Thanks guys for your time.
Best regards.
