PD14 will not generate shadow files from imported 4K 265 HEVC material

W/O those files it is impractical to edit 4K HEVC files.

However PD14 will import and convert that material to SD format, those files can then be imported into PD and edited normaly.

Shadow file generation is turned off.

Replacing those SD files with the original 4K HEVC will allow final output produce in that format using the same file name.

Using a GTX 960 GPU will do both conversion and produce in about twice real time, with hardware encoding, (no transitions etc used).



This method has been mentioned a few times on this forum during the past years as a means to speed up the inherently slow PD shadow file generation.

It will also allow editing of 4K HEVC video in PD14 if a GTX 960 GPU is used.

The process works on my 5 year old computer and just about as fast as editing in 4K 264.

Eugene, thanks for recommending the work-around.

I've seen other posts about PD14 not creating shadow files, but I see it doing it right now with 4k MP4 H.264 clips:



Is the issue only with HEVC clips straight from a camera, or does it happen if you produce a clip to HEVC in PD and then import it?

Why do you even need shadow files ? I have been editing without shadow files all these years .

I turned them on recently but didn't notice a difference. I have been mainly using H.264, not HEVC, though.

In what situation do the shadow files help ? MSI X99A Raider

Yeah, there's no activity at all when I opened a new project and imported put the 4k clip I just produced to HEVC with SF turned on. Nothing sealed
