Hello again.
I have been trying to register and stack several ser videos. I am using OSX El Capitan on my iMac.
My Mac can easily handle more than 1000 frames, but the stacking output log says it cannot.
It suggests either using the "Summing" stack method (doesn't help) or convert the thousands of fits frames into an ser sequence before stacking. I do not see how to do that. Please advise me as to the best workflow for processing several ser videos.
Merci.
Fred

Load all your files in the conversion tab and choose a sequence name ending with ".ser".
In fact there is a third way to process many files on macOS: https://unix.stackexchange.com/questions/108174/how-to-persistently-control-maximum-system-resource-consumption-on-mac

Hello again lock042. Thank you for your quick reply.
Although I will try the first suggestion, I think the main issue is as I wrote, that Siril thinks that I have that 1000 file limitation.
None of the other stacking apps show that issue. I used the same SER videos with an older version of Autostakkert, in a Wine type wrapper, and it worked just fine.
Also as a feature request, for a future version of Siril, can the SER videos save the stacks as one tiff or fit file, instead of one for each of the SER input videos? That is how it worked when I loaded just two or three SER videos.
I then had to re-stack the two or three stack files to get just one final file.
If I am doing something wrong in the workflow, it may be because the info in the user manual is quite lacking, for processing SER videos. That area needs to be expanded with steps and examples for each module, such as is the case for processing images.
Thank you again.
Fred

The way siril uses your FITS files is not the same that other software. Siril needs to open all your files in same times for statistics.
So it is a problem of macOS limitation i can garantee you (especially if you have siril 0.9.11). Follow the url or convert into ser format for no limitation.

Hello again lock042. I tried the first method. I loaded all the files and input a sequence ending in .ser.
Siril produced that sequence and I was able to get a stack. Unfortunately, the stack must have gotten corrupted near the last portion since no app can read it. Siril, and Autostkkert start to load the .ser stack, but give an error near the end of reading it. The error says "cannot read the file". all the Siril produced fits frames can be read with no problem. It is only the final stack that gets corrupted.
Do you have any thoughts as to what may have caused this?
Thank yo.
Fred

Please, give me this final stack

Thanks for your assistance lock042. I was finally able to get Siril to produce a good stack,from the several ser videos I loaded.
I was wondering about a future feature for Siril. Could image stabilization be added such as are implemented in PIPP and Autostakkert? That would further improve planetary stacks, from videos, captured under poor seeing conditions. I live near a mountain range and that causes jittery seeing conditions, due to the foothills air turbulence.
Image stabilization could help somewhat with that issue.
Thanks again.

Hello fred,

A version of Siril specifically dedicated to planetary image processing is being developed.
