Batch Deinterlace in Photoshop CS2

It *should* be possible to deinterlace stills using Action/Batch but we're unable to make it work.

Following the Action process: Open-Deinterlace-Resize-Unsharpen-Save-Close; the resultant files are re-sized and unsharpened but not deinterlaced.

Has anyone run this process successfully; we don't fancy doing the job manually as there's over 2000 images?

Alternatively, a pointer towards a piece of software that will do the job will be appreciated.

Mike, I have a folder of actions called "Video actions" - not sure if it came with CS2 or I acquired it elsewhere! - has an action for "interlace flicker removal" - works well, email if you want it.

The 'Video Actions' are not shown as default if you hit the flyout (little circle witha right arrow in it top right if you've not used it ebfore) tab of actions it should be at the bottom.
It might also be best not to record the open and save/close parts in your action the batch should do all this for you and it can get a bit 'up tight' about this sometimes.

Dave, thank you.

Yes I have the folder; must get my eyes tested:)

I'll give it a try later.

Kind regards

Dave, I'm not sure what the Flicker Interlace Action is for but it certainly doesn't deinterlace in the same way as manually using the Filter/Deinterlace tool.

Nick, do you think it's possible that the deinterlace is not working in my recorded action because I have "Open" and "Close" commands?

Presumably I open the first image, start recording the Action then stop recording after "Save" and before I would normally "Close" the Action - OK, I'll give it a try - anything rather than manually process 2000 images :)

Kind regards

Mike

It could be if you record a save action it might stop it doing it properly, if you get stuck send me a sample file and I'll have a go.

Nick, hi
It seems to be the "Open" action which was preventing the "Deinterlace" however, dropping the "Open" action and/or the "Close" action then stops the batch at the point where you accept/adjust the amount of compression causing each process to require a manual click on "OK".
This Action/Batch process is a bit bizarre.

HI Mike,
I'll have a try in a bit and see if I can come up with any ideas are you on CS2?

HI Mike,
I think I have found the problem and hopefully a way round it. I've made a small video showing what to do.
You'll need Flash Player 7 or above to view the link below, hopefully it will help.
Please excuse lack of production value I just had to knock this up quickly, any probelms let me know.
If Flash is no good for you to view let me know what is OK (WMV,QT etc) and I'll upload a new version.

It will take a few seconds to buffer but not as long as the preloads says (bill gates time).

Thanks Nick, your tutorial was brilliant!

Firstly, it highlighted to me that having jpgs is not good starting point because of the re-compression that Photoshop will want to impose, but that's what I'm stuck with. Normally I would grab images as uncompressed TIFs.

The second is the fact that you moved from Photoshop to Image ready when I had remained in Photoshop for the whole process.

I will now need to do some experiments.

Many thanks for your help.

Kind regards

HI Mike,
Glad to help, you can easily modify what I did to save out files as TIFF so you dont get another round of compression. Where I did 'save for the web' (CTRL+ALT+SHIFT+S) you could select 'save as' (CTRL+SHIFT+S) and pick TIFF in the same way, same flow should still work for you.

Hi Nick

It seems to me that I need to batch process the images from jpg to uncompressed TIFF then run the batch process to deinterlace, resize, unsharp and finally into Image Ready to save back out as jpg's

I must say I don't like the idea of all this compression and recompression but I don't seem to have a choice.

Many thanks and kind regards

Mike

HI Mike,
Seeing as its lunch time you want me to give you a call and run through this might be a lot quicker.

Nick, Dave, thank you both for your help with this; we have now cracked the problem.

It seemed to be a three-fold issue. The process in Photoshop didn't like being told to "open" or "close" images and it also seemed to shy aware from batch processing jpg's.

We took onboard all your suggestions and advice and finally achieved success when we converted all the files to uncompressed TIFF's, removed "Open" and "Close" instructions then used 'Save For Web' (Image Ready) to return the files back as compressed jpg's

Again many thanks

Kind regards

Mike
