Checking file integrity of an image seuqence of JPG
Hi,
I’m rendering some images sequences of some thousand sequence files, using multicore render (render garden).
It’s an amazing piece of software, but sometimes render’s do fail, and I’m stuck with a couple of image files that are corrupted (invalid headers, half images, half rendered, etc).
One of the easy way’s to try to locate these corrupted files, is to sort them file size, and the small ones, didn’t finished render or are corrupted, so I delete those and them render again,
<font face=”inherit”>However there are some files that have been partial rendered and the file size is very close to the other normal files, and it’s just </font>impossible<font face=”inherit”> to know witch ones are </font>corrupted<font face=”inherit”>.</font>
In ae preferences>import I do chave check the “report missing frames” and “verify individual files” checked.
Question:
<font face=”inherit”>Is there any software that can scan JPG folders containing image sequence and test the </font>validity<font face=”inherit”> of those files, before I imported them into AE?</font>
<font face=”inherit”>
</font><font face=”inherit”>thanks</font>

If you’re comfortable with a python-script, there’s this:

Thanks Filip,
Nope, I’m not familiar with pyton, I’m looking for a simple gui app, that can scan a dir and gives me a list of bad files.
There are countless jpg/file repair app’s outhere, I don’t want want to repair them, I just want to know, which files are corrupted.
thx

I would try this:

Thanks Roei,
Ramma is what I’m looking for, the only thing;
it’s quite expensive (85 euros) for what it does.
Any other tool that can do this?
this is the correct link for ramma, since in the letterbanks link is wrong.

thanks for correcting the link. I am not aware of other tools, it’s not a personal necessity in my projects and I knew Ramma existed.

In the process of trying to find any soft that can do this I came across the image sequence scanner, it’s free but it’s in beta
https://sourceforge.net/projects/imgseqscan/
There should be some program out there that can do this, due to the installed base of ae and animation users.

To be fair there is a program out there (more than one) as you’ve found; they’re just not the cost or UI that you’d prefer.
One method that I’ve used is to open the directory in thumbnail view; it may take a while but generally I find the miscreants in time.
Something like Adobe Bridge might help with this too, as you can choose to show files within subfolders.

Thanks Chris,
I did tried to use thumbnails, but in a a large image a single line or half line of bad pixels, can’t be seen in the thunumbails.
By some reason the thumbnails will render in file explorer (win10 pro, but in ae the render fails.
When I say a price point, render garden costs 99US, and is able to speed up your ae render times by 100% (it’s like having two computers with the same specifications running inside a single machine).
Ramma is costing 72US, just for scanning a dir and report bad files.
Anyway, just asking what it’s the soft app that people are using to get the bad files,
I just want it to scan a dir and report the bad files in a text format, so I can locate them in, delete them, and restart the render.
I don’t need to know why they are bad, they are bad, ae can import them, but it can’t render them. I don’t need any fancy gui, showing the files, and their location and the reason they are bad.
Just to recap,
1. rama (seems the professional choice, it seems (85 euros)
2. pyton script
https://github.com/ftarlao/check-media-integrity
3. Image sequence scanner (free but beta)
https://sourceforge.net/projects/imgseqscan/
Any other input, thanks
pedro
