I know in importing video frames it only allows 500. You may be running into similar problem, and/or resource limitations.
But then why 471? Is there a way to raise the max? My machine can take it- it has no problem processing large quantities of images. I could have swarn I opened more than 500 images using image sequence before, I make timelapses.
Is your system and photoshop 32 bit or 64 bit? You may be running into a ram issue.
I run 64 bit. I'm pretty sure it is not a computing power issue. In all my experiences the program and computer would try to attempt it and then fail, either not responding or closeing all together. It is not adding all 873 photos.
What kind of ram issue might I be having?
Yea. Not a ram or computer problem. I run a beast. I'm not sure what it was. I opened all 873 images in camera raw, gave a slight edit, saved them in a new folder in a new drive, with new names, and THEN opened it using image sequence..... It worked. Must have been something funny at image 471 because it keept stoping there before.
Thanks for the troubleshooting help.
Just because Photoshop supports many layers it does not mean Photoshop will perform well with many layers. And there are different limits for many things. Like 53 Alpha channels is Photoshop limit. For example I dropped a music video onto CS6. Photoshop opened it and played it without problem. In the Timeline flyout menu I used the option to flatten the video into frames. It took forever and a day to do that. When the operation was done I saw there were over 7K layers in the layers palette by the top layer name. Photoshop was still working on the layers palette. It had not rendered any thumbnails yet in it. It took an other 15 or so minuets to do that. Then I could scroll the layers palette painfully slow. It took much time to delete a 1000 layers. Each time I delete a 1000 layers Photoshop performance improved. When I has 1000 layers remaining. I rendered a image sequence using 1 FPS as the frame rate. 1000 jpeg files were saved. I close al the documents in Photoshop I had open. Then opened the 1000 image sequence. It opened a a video and when I flattened the video I saw 1000 layers.
The script load files into a stack would only load about 281 jpeg images out of the 1000 files. It depend on the feature you use and your configuration. I saw Photoshop turn off OpenGL at one point for files some limit was hit. OpenGL and GPU was not turned off for all open documents just new ones. My workstation has 40GB ram and dual 6 core xeon processors and a few hundred GB of scratch space. Mileage may vary..
What is too often underestimated by too many users is the amount of free disk space available for Photoshop's scratch.
My personal rule of thumb is to figure on up to 50 to 100 times or more the size of your largest file multiplied by the number of files you have open.
I use Photoshop practically only as my digital darkroom, never work on video, so the numbers of simultaneously open files being bandied about here is completely beyond me.
