I am fresh from a 3 hr session with LR slideshow module. Having satisfactorily created a couple of slideshows, I embarked on another. However, after several attempts when nothing seemed to happen, I decided to experiment with the number of slides, since there were more than in my previous two attempts. I got as far as 35 slides, before hitting the buffers (I’m not sure if this a pun?). During each process, I used Task Manager to monitor CPU and Memory usage and neither came close to be fully utilised. So I explored LR settings through
Preferences. I noticed that under
Performance, the video was set to 5Gb, I think. I changed the setting to
do not limit and restarted LR. I managed to get up to 50 slides but that was it.
I began to think about a GPU, but most seem to be 1 – 2Gb, so I am not sure if that would help greatly.
Finally, I decided to try exporting all the Raw and DNG to jpg, saving them into the original folder, then using these to create the Slideshow. That seemed to work ok. But I have several folders much bigger and wonder how these will work out.
The downside is I end up with a lot of jpgs, but if I just wanted to copy my photos onto a USB stick to show on my TV, I would have to do export them as jpgs anyway. As it is, once I have created the Slideshow, I can delete the jpgs.
If all this seems longwinded, it appears that the Slideshow in mp4 format is significantly smaller than the collection of jpgs.
After I had written the foregoing, I dimly remembered being told that programmes are often limited to how much of the processor/RAM they can be allowed to use. A quick Google search led me to a page with these simple instructions:
Step 1: Open the Task Manager app on your Windows 10 computer. For this, press the CTRL + SHIFT + ESC keys on your keyboard.
Step 2: After opening Task Manager, go to the “Details Tab.”
Step 3: Now, right-click on the application that you want to allocate more RAM. In the context menu, hover to the ‘Set Priority’ and choose ‘High’ or ‘Above Normal’ based on the priority.
Step 4: Once you make the changes, you will be asked to confirm it. Do so by clicking the “Change Priority” in the confirmation box.

I did this and hey presto – it worked. I immediately exported the 86 Raw & DNG picture slideshow to mp4 that I had been struggling with. I have now done one with 310 pictures, resulting in a 1GB mp4 file, with no problems.
