Lightroom Craps Out With Videos

This is a tale of a problem I got in to with Lightroom.  I Googled solutions for this and got a bunch of suggestions but none of them worked.  In the end, Adobe sorted out the issue but I wanted to share what happened in case anyone else experiences the same issue and ends up Googling like I did.  Maybe this post will help someone out.  The source of the problem was an MP4 video file that apparently had some corruption within it.  This screwed up stuff within Lightroom that needed some detailed work to fix.  First, I shall tell you what the main error was.  This might be what someone is searching for.

Dynamic Link Media Server Failed to Launch

The result is that video files don’t import and then you seem to struggle to preview videos at all.  When you are in the Import dialog, the video preview doesn’t show and an icon of a camera comes up instead.  Some of the recommendations online were to delete the Dynamic Link Media folders in the App Data section of Windows and restart but that didn’t help.  I also tried that and deleting the media cache but no luck.  Next was to delete the Preferences folder for Lightroom which can often be a solution for unexplained problems but that didn’t work either.  That is when I got Adobe involved.

The support engineer tried a bunch of things.  Eventually, he created a new user on the machine and opened up Lightroom in there.  We tried importing a new video file from the same camera and that worked.  He then set about deleting the Lightroom related app data in my user profile and replacing it with the data from the new User.  We then tried importing the new file and it worked fine.  Next was the previous file and that caused the same problem as before.  Now we knew the file was the problem we could isolate that from everything we did afterwards.

Of course, I had damaged Lightroom again but now we knew what was required, it was a simple task to copy the folders across again.  The only downside to this was that all of my presets and information got deleted.  However, I had copied the old Lightroom folders before starting all of this.  It wasn’t too tricky to replace my camera profiles, develop presets and plugins.  At first I thought I had lost some functionality that I really like.  I have a plugin called LRInstagram which allows me to post from Lightroom to Instagram directly.  Facebook has turned off the ability to do this so, if you install the plugin now, it won’t work.  However, something about my legacy setup meant I had still been using it.  When I tried to set this up again, it failed to work.  However, my old Lightroom folder had a sub folder for the plugin which contained something like a cookie and, when I copied this across, I was back up and running!

All of this is to say, if you have a similar problem to me, there is a solution.  I won’t lay out the files that are involved because it is a bit tedious and there are some other things to bear in mind but, if this happens to you, get in touch and I will talk you through what we did.

Putting Together a New Gallery

I was pondering the content of the gallery on my website.  I hadn’t updated it for a long time and thought there were plenty of shots that should be in there that weren’t.  I started compiling a folder of shots for the revised gallery.  I thought I should check the old gallery to see which shots I should carry across and, when I went to open it on the website, it didn’t work.  It turned out the design was not compatible with current browser design!  I have no idea how long it has been out of commission.

I looked at what options there were for alternative gallery designs and was struggling to find one that I liked that did something special.  In the end, when concluding that a simple design was what I was going to end up with, I went with one of the templates within Lightroom.  That made creating and updating the gallery a lot simpler.  The revised gallery is now online at the link at the top of this page or, if you can’t be bothered to click up there, here is the link.

Negative Lab Pro 2.0 Update

A while back, I bought the Lightroom plugin, Negative Lab Pro.  This is a plugin that converts digital images of negatives to a positive image.  I wrote about it in this post.  A short time ago, the developer brought out a version 2.0 upgrade to the plugin.  It turns out, the upgrade was free for those of us that had bought the original plugin.  I installed the upgrade to see how things have been improved. 

Initially, I was very disappointed.  The conversion process after the update seemed to be awful.  Things looked dark and blotchy and efforts to unconvert and reconvert the images didn’t help.  I was perplexed by this since a number of users had already exclaimed how happy they were with the update.  If in doubt, follow the old approach of closing stuff and restarting it.  I closed Lightroom and reopened it and whatever was wrong before was now fixed.  The conversion worked very well.  The controls have been expanded to give you a bit more to play with.  The main benefit I am seeing so far is in the color balancing.  Shots seem to have a more natural look to them without me having to work too hard on the color in the first place.  Shots like those with a lot of sky and an odd colored aircraft will still test the algorithm a lot but otherwise it seems to have a good handle on things.  It is also now able to handle frame edges without getting confused.  You can tell it how much of the edge to ignore which is a useful feature although I have got into the habit of cropping carefully already.

All in all, the upgrade seems to be a good one.  Since it hasn’t cost me anything, that is a nice thing to have.  It is also good to know that the developer is continuing to work on the product which holds out the hope of further upgrades to come.  I continue to recommend this to anyone that has been scanning their old negatives with a digital camera.

HDR Tech Comparison – What’s Up Lightroom?

A while back I saw a Scott Kelby video on YouTube about the HDR functionality in Lightroom and that in Photoshop.  I had assumed that they were the same prior to seeing his video but he showed that the Photoshop version of the HDR was significantly cleaner than that in Lightroom.  I was interested in how this could be but I wasn’t too concerned.  The Lightroom version was so easy to use I figured the impact was not so much that it would show up in my shots.

Then, I found out I was wrong.  I was in the cockpit of the Comet at the Museum of Flight’s restoration facility at Paine Field.  I took a sequence for HDR because the cockpit is very dark but the view out of the windows is much brighter.  It isn’t particularly important since the view outside is nothing special but I did it anyway since I was there.  The lighter shot had quite a bit of shadow noise and, when I created the HDR in Lightroom, the noise was very conspicuous on the finished version.  I decided to try it in Photoshop to see what happened.  The difference was significant.  I include both of the full shots as processed along with the section of cockpit shadow so you can see the impact.

Recovering a Crashed Card

I was downloading shots from two cards into Lightroom when one of the downloads seemed to hang.  I have seen this before and on those occasions, removing the card and starting again did the trick.  This time it didn’t and, when I reinserted the card, the computer said I needed to reformat it.  I thought I would try it back in the camera to see if that was okay but no joy.  Time for RescuePro Deluxe again.  I wrote about using this previously.  I had an issue with it one time when I tried a recovery and the same thing happened this time.  The card drive letter doesn’t show up (nor do any of the others).

There is a simple fix to see them all which is to press the H key.  However, I hadn’t made a note of that previously and couldn’t remember.  Fortunately, their help desk gave me the code and the pictures were all swiftly recovered.  (I jest.  The program works well but recovering everything it can find on a 64Gb card and then working through that to find the files you really want rather than something from months previously is a bit of a slow process.  Still, it is a lot better than the alternative of having no shots!)

Negative Lab Pro

In previous posts I have described my efforts at scanning old negatives using a digital camera, macro lens and a light table.  I have had mixed success with the process for converting the negatives into positives with some films responding better than others.  I was okay with the output but thought things could be better.  A YouTube video showed up on my page that was about scanning negatives with a digital camera and I decided to watch to see if they did anything different to me.  The technique for shooting the negatives was similar enough but they introduced me to a Lightroom plugin called Negative Lab Pro.

I downloaded a trial of the software and gave it a go.  I was sufficiently impressed with the output that I stumped up the cash for the full version.  It isn’t cheap but, given that I can now use it on several thousand images, I figured it was worth the investment.  The plugin requires a small amount of effort.  I revert the images back to a normal San without any of my previous edits and conversions.  The first thing to do after that is to take a white balance reading from some of the visible edge of the film to neutralize any color shift.  Then you crop in on the image.  Apparently, it is important to avoid getting any unexposed edges in shot as this messes with the algorithm.

Then you open up the dialog box.  It analyses the image and does a conversion.  You then get some basic sliders to tweak the settings such as exposure and color balance.  There are some auto setting check boxes but I haven’t found them to be too helpful so far.  Then you click okay and the image is ready to do further editing in Lightroom.  You can also do batch conversions of images if you want although I think it is probably better to focus on individual processing.  I have been playing with this on a range of images so far and I like the results.  My old negatives are not that great and this is not going to suddenly make them amazing but I am impressed how much more I can get out of some of the scans using this software.

Video Editing With DaVinci Resolve

While it is not what it was designed for, I have been using Adobe Photoshop for my video editing for quite a while now.  It did enough for my purposes so I couldn’t see the point in investing in new software purely for video.  However, I was talking to someone hat was starting to play with video creation and they wanted something to work with, so I looked around at what was available.  I saw that DaVinci Resolve, while available as a full feature video editor commercially, came also with a free version that seemed to have a lot of the features that the basic user could want.

Since I was potentially going to recommend this, I figured I ought to try it out myself first to see how it worked.  I have to say I have been very pleased with it.  There are clearly plenty of features in even the free version that I am unlikely to take advantage of.  It is also a lot more user friendly than Photoshop when editing video (which is hardly surprising given that is what it is designed to do).  I have played with a few edits now and I am starting to get the hang of it.  One lesson I have learned so far is to choose the continuous save option.  I spent a lot of time on an edit and the software locked up after lots of work.  The whole thing was lost.  Now it keeps a running save going (although I haven’t tested that properly as it hasn’t crashed since).  This looks like it is my new go to for video work.

Lightroom 8.2 Detail Enhancer

Updates to Lightroom come along relatively regularly and they tend to include new features along with fixes and performance tweaks.  The latest update, Lightroom 8.2, includes a new addition called Detail Enhancer.  This is a feature that is designed to provide some better small-scale detail as part of the raw conversion process.  It creates a new DNG file based on a more complex calculation of the demosaicing of the sensor data.

I saw some videos about it and figured it wasn’t going to be of much use for the type of thing I am working on.  However, it did trigger one possible area of interest.  The algorithms are supposed to be designed to make better calculations around the different color pixels that sensors have.  Sensors are set up in a Bayer Pattern where different color sensitive sensors occupy different pixel spaces.  They each record in one color and then software interpolates between them to create colors for each pixel irrespective of which color was originally recorded at that location.

In a post from a while back, I mused on the way in which the colors of the Southwest Livery and the registration clashed and seemed to provide a distorted image even when everything around them was sharp.  I was pondering whether this was artifacting caused by the different colors and the way the sensor was recording the data.  If this was the case, maybe this new functionality would change the way things were rendered.  I dug out a few of the shots that had previously demonstrated this effect and ran the process on them.  These shots show the wide shot, the original rendering of the close up and the revised rendering using Detail Enhancer.

As you can see from the comparisons, Detail Enhancer does not suddenly render a perfect registration for the aircraft.  However, to my eye at least, it does appear as if the results are noticeably better then they were with the original rendering.  For completeness, the original rendering is done with the latest process version of Adobe’s raw converter to make things as fair as possible.  It does appear to make a difference.  This makes me think my theory about whiny things looked wrong might have some merit, even if this update has not fully resolved things.

Focus Stack Animation

In some previous posts I showed the results of experimenting with focus stacking.  In those posts, I would combine one of the individual shots with the finished effort to show how shallow the depth of field could be on individual shots and how deep the focus was on the final image.  I was pondering whether this was an effective way of communicating the concept to someone when it occurred to me that animation might be a better way.  I created a new stack of images for a different subject but this time I used Photoshop to animate the movement of the point of focus through the shot and then show the final image.  This can then be an animated GIF.  I wonder, does this provide a better demonstration?

Learning a Better Way to Blend in Photoshop

I occasionally use the Statistics function in Photoshop to blend multiple images in order to get rid of the distractions that I don’t want like people or vehicles.  Up until now, this has been a real pain to do.  I would identify the images in Lightroom but would have to open Photoshop, go into the Statistics function, use the browse function in there to select the images and then it would run everything in one go.  This was not a convenient way to go and the output image then needed to be manually added to Lightroom which is not handy.

It turns out that there is a better way.  This may have been in Photoshop all along and I never knew or it could have been a recent addition.  Either way, it is there and I shall now use it for future projects.  I have even created a Photoshop action to cover the process and assigned a function key so it will now do the heavy lifting without my intervention.  It all starts out in Lightroom.  Select all the images that will be used for the blend.  Then use Edit>Open As Layers and a new document will open in Photoshop with all shots as layers.

If everything has been shot on a tripod, things will be properly aligned by default but I often do these things on the spur of the moment so they are hand held.  Consequently, while my efforts to keep pointing in the same direction are not bad, the first task is to select all layers and Auto Align layers to tidy things up.  Next, go into the Layer tab and, under Smart Object, convert to a Smart Object.  This may take a little while.

Next step is to go back into Layers>Smart Objects>Stack Mode.  This brings up the same options as you get through the Statistics function.  Select Mean and send it on its way and you end up with a shot that, depending on the number of shots taken and the clear space in enough of them, results in a clear shot.  Usually I find that I haven’t got enough shots of the right type to get everything to disappear so some ghostly elements may remain but they are certainly less distracting than the figures in the original shots.  I have no idea what the other modes will achieve and the descriptions Adobe provides in their help files are so obscure as to be virtually useless. Instead I shall have to experiment with them to see what happens.  Thankfully, now I have this new method, I can undo the last step easily to try each option which would not have been possible using the Statistics dialog.  Another win!
