Batch File Conversions

I have several hundreds of digital images in many different sub directories. I need to convert these images into a specific size and format (Targa) for inserting into video timeline. Is there any way that this file conversion can be done in a folder batch rather than painfully resizing and formating individually ! I use Adobe Photo Shop 6.0.

Hi,

Canopus has released ProCoder, a Windows software application that can take almost any video file and compress it into almost any other type of video file. I believe it does in whole batches, but it costs £400 to £500 pounds.

MicroGrafix Publisher does this, but I'm not sure that it's still sold ?

I'm not sure you actually need to do it at all. You can probably drop the images into your NLE and let it take care of the pixel numbers, provided the shots are all 4:3. If you want to crop them, you can probably still do that in the NLE. As long as you have sensibly more pixels that video needs, it should all work (800x600 would be fine, anything better is a bonus).

Could you not use the Actions facility of Photoshop to do a batch change to the new format? Resizing may be more tricky if the originals are different sizes.

Another program that will do batch conversion is Irfanview which can be downloaded from the web.

Hi,
Infanview can batch convert although you have to (i think if i remember right) add each image to the "batch" by double clicking on it with the mouse.

Once all files included though it will then batch convert to any file you point it to.

And is a free download.

John, Thanks for this information, I will give it a try this week end. I dont consider problem with re-sizing as all images are same in each folder. I use Matrox RT2500 and I have found that to use TARGA format for digital images (rather than say JPEG or TIFF) there is no rendering required when I have built up a slide show on Premiers time line.

Alan,
Thanks for your reply, I have found that using TARGA format for digital images on Premiere Timeline using Matrox RT2500 there is no rendering required. I am fairly new to video editing (just over a year) and I am always open for better ways.

Stuart,
Thanks for this information, I will certainly have a look at this programme as soon as I can.

Dear Dave, no probs
I do know it will batch convert targa format, tried it a few times today to make sure

Best wishes.

Stuart,
I have downloaded infranview, quite a decent programme as far as I can make out. Very simple to use and to convert a folder of about 80 images to targa didnt take long. The only thing is when dropped on Premiere Time line they need rendering. (Matrox 2500 card) where as if I convert individually using Photoshop 6.0 then drop them on the line no rendering is necessary. Any ideas about this. I will mess around and make a few adjustments here an there to hopefully correct this situ. Thanks for the "heads up" with Infranview, I realise that it has other attributes that interest me.
Very Best Regards
Dave.

RT2500 needs 32bit TGA's @ 720 x 576 for full realtime operation.

However, there is another option worth considering - I'll try to explain it without getting to bogged down in detail - plus it's theory - I haven't tried it.......

Open Premiere, select "edit>general-still image"

Set the default duration for still images to 1 frame.

Import your still images to the project - you can use the usual windows shift/ctrl keys for multiple file selection.

Select the images in the project windows - again use shift/ctrl to select multiple files and drag them to the time line.

Choose file>export>movie then change the MatroxRT (or similar) setting to TARGA Sequence.

Now you should have a series of numbered stills that when re-imported will play in realtime.

Note: I haven't actually tried this - it's theory - so I'm not sure of you need to change the field order settings for the project to "none".

Hope it works !!

Gavin

Hi.

Bit late on this thread (been on hols) but you can batch resize in Photoshop using the "Fit Image" command (File>Automate>Fit image...) if you include it in a Photoshop Action.

With "Fit Image" you basically define a pixel dimension for the final image and photoshop takes care of the resizing - simple. What's particularly useful is that you can specify a 'square' final dimension (eg 500 pixels square) and Photoshop will resize the longest edge of any image to that size - so you don't have to batch-size the landscape and portrait images separately.

Record the action, then run it as a batch (File>Automate>Batch) and point it to your source folder. Probably worth trying it out on a small folder of images first - and don't forget to specify a different folder to save the resized images into..!

Hope this helps.

Peter
