Render/produce time when using "Highlight healing"

I think this little thread typifies the current flavour of the forum.

Robert made an interesting observation, quantitatively measured, of a new PD11 feature, he made a couple of light hearted points, to illustrate the apparently significant effect of the use of the feature.

djmorgan gave a subjective opinion, and opined that Robert was making a generalisation and, in effect, overreacting.

Robert had the courtesy to expand on his position to try and remove any misunderstanding and clarify his points.

djmorgan chose to "pick out the bones" but without any quantitative data for others to go on, again giving his opinion and asserting Roberts post was a "sky falling in" post and he was incorrect.

Leaving aside the next section, where Robert retired from participating.

Jeff then then quantitatively confirmed Robert's findings and passed a couple of comments on the feature process itself.

Myself and Tony quantitatively confirmed it as well.

From my perspective, Robert's observation on a new feature was a valid one, backed up by more than one observation from others, but the issue was clouded by an alternative opinion which was entirely subjective, missed the point and arguably, was a little confrontational, and so the thread started to dribble away into not a lot.

Ah well.

Hi Adrian,

As an aside to the actual problem it is very interesting from your results that with the infliction applied,
CPU rendering time increased by 3.4 times while Quick Sync rendering time increased by 7.8 times.
More of a mystery as the virgin clip with Quick Sync was 3 times faster than with CPU rendering.

Something I notice with windows 7, and not just PD11, is that there are times when the system seems
to be busy, but there are no apparent increases in CPU/GPU or Hard Drive activity.
During these times I wonder what is actually happening inside the magic box.

Probably Win 7 customising itself to enhance the customer experience by drawing on an an analysis of the recent usage patterns of not only you, but also of your friends and people in your contact/address book/social networks who bought/used/posted/viewed similar things/sites/people that you might be, but in my case am almost certainly not, interested in.

Adrian

Might it be that the healing technology is not compatible with the qs IC approach to video processing. In other words, the healing aspect may be done by the cpu and the encoding by qs, so one essentially has a significant burden of the cpu's for healing in the qs numbers leading to the significant ratio difference. I did notice that my CPU's were running part throttled during the healing vs unhealing comparison which was unexpected.

I think it would be great if CL could take a performance look at this feature, I don't use these types of features but additionally don't see why it should be so slow on a relative basis either. Could be some coding inefficiency that when corrected could help those out who use these features.

Additionally, what PD11 has done with next generation of TrueVelocity3, cpu and multi-GPGPU encoding is currently somewhat a mystery to me. I only know my CPU encoding of about 15 different projects have a 5-30% slowness factor relative to PD10, same hardware.

Can anyone one comment with some personal experience using the TrueVelocity 3 and the Multi-GPGPU encoding?

I would be interested in knowing more.

Do I have to start a new topic? Not really sure as I am expanding on Jeff's comment.

Edit( yes I edited my response, I didn't delete anything, simply added to my thoughtful question). Looking for objective data not a subjective opinion regarding this question. Thanks in advance.

Can someone please let the rest of us know what highlight healing actually does to their project ?

Anyone ? Win 10, i7

It appears to try to recover blown out sections of the video, similar to recovering blown out sections of photos when using Photoshop or Lightroom.

In one video I tried it on though if I turned it up too high the clouds in the sky started blinking as if it worked in one frame but not the next. To stop the blinking I had to turn it down so low as to make very little difference.

I think it is a good idea but needs more development. My youtube channel====> http://www.youtube.com/user/relate2?feature=mhsn

Hi Robert

Have you tried ColorDirector to do this?

I've found it very good on white balance and colour grading.

There are some handy 'toots' in the ColorDirector forum page.

Happy editing

Thanks Neil, I had a quick look at the tutorials, don't have colour or audiodirector installed. I am though at a stage in my editing of......"minimum effort, maximum result" so I think I might pass on those two for the time being.

EDIT: Again, the moronic star fairy attempts to crowd out positive & reasonable discussion with its cowardly thuggery. No matter. Just sorry that you have so little to contribute. Members here are simply exploring new "features" of PD11, just as the forum is designed to accommodate.

I agree with your assessment, Robert. Even though the help file & user guide is strangely silent on highlight healing, it appears to be aimed at restoring details in over exposed/blown out clips.

Quote: In one video I tried it on though if I turned it up too high the clouds in the sky started blinking as if it worked in one frame but not the next. To stop the blinking I had to turn it down so low as to make very little difference. I think it is a good idea but needs more development.


Yes - found the same thing. "Blinking" would be a generous description. some of my produced clips with highlight healing applied at 25%+ looked like they were shot in a lightning storm. S0 - yes - a bit more work to be done.

I know the topic is shifting in this thread but, following up on Neil's suggestion about ColorDirector, Highlight Healing in PD11 is, I think, akin to some of the tone adjustments in CDR. Using the same clip, I produced similar results by decreasing the brightest tones in CDR. ColorDirector, however, produced its video without blinking & lightning strikes... & did it in about half the time.

I was hoping highlight healing would work on a video the same as "Shadows/highlights" in photoshop. That is you can adjust the highlights and shadows separately.

In my hanggliding videos I am in shadow most of the time hanging under my wing and the sky gets washed out a lot of times. Not too bad if it is a cloudless sky I just pump up the saturation a bit. When it has white fluffy clouds is when it looses that last 10% of quality.

I 'll download the trial ColourDirector and give it a go. My youtube channel====> http://www.youtube.com/user/relate2?feature=mhsn

Well I downloaded the trial. Yes it does a pretty good job, although the trial doesn't allow me to produce HD so I can get a better look. Also $129 is too expensive to get that last 10% out of my videos. My youtube channel====> http://www.youtube.com/user/relate2?feature=mhsn

Looking at Tony’s comparisons, and following this quite interesting thread, I am wondering:
If I have gotten what has been posted, I am missing (the consept) gamma.
In PHSH, as Robert said, you have the “shadows/highlights” you adjust separately. But you
also have the option to correct “gamma/exposure”. Together, these tools can do wonders with
over-/under exposure.
From what I am able to see from the comparisons, the “highlights” seem to be somewhat corrected,
but the shadows seem to be suffering (flattened/greyed ?)

Nina

Maybe you're looking at it sideways.

If I understand you correctly, the problem seems to be that you can't manipulate the compensation curves directly. Do you see the eyedropper in the "White Balance" area? This manipulates one end (the white end). What's missing are eyedroppers for black and, potentially, grey.

Photo editors would have those manual adjustments, and more, but PD doesn't. Jerry Schwartz
