Jpeg Document Quality Enhancement in After Effects
on Jan 17, 2013 at 5:34:12 am

I have JPEG documents that I would like to increase the quality of so I can use them within After Effects. What is the best option to accomplish this? I was thinking of converting them through Illustrator or using an OCR program. Any suggestion would be appreciated, thank you.

The Illustrator route won't work, because you're working with a bitmap within a vector based software package. You can't improve a bitmap file in Illustrator. The quality (or lack of) is baked in.

Here's a runthrough on what you can do to improve the quality of a .jpg:

Some of these answers seem a bit misleading.

I suggest trying to bring the jpeg into illustrator. If it's a good scan but you want something to blow up without quality loss then give Illustrator's live trace. It will convert bitmap images to vector outlines. If things seem a little blotchy then tune the settings.

If this doesn't give acceptable results, there are all kinds of OCR programs at different price points. Once you get the OCR result saved as a PDF then you should be able to open it in Photoshop and scale it quite a bit since it's rasterizing a vector based font.

Not misleading at all, Angelo - a bitmap is a bitmap, and if there's aliasing in it, no amount of live tracing is going to improve it, short of lowering the quality of the trace, which will round the edges of the type and make it look even worse.

[Angelo Lorenzo] "I suggest trying to bring the jpeg into illustrator. If it's a good scan but you want something to blow up without quality loss then give Illustrator's live trace. It will convert bitmap images to vector outlines. If things seem a little blotchy then tune the settings."

Live Trace is a feature that I have tried on dozens of images, but actually only been able to use on a few. It usually ends up being faster for me to hand-trace things (logos etc.) in Illustrator than it is to try to tweak the settings to get a good-looking Live Trace.

There's no harm in trying, but I have never gotten satisfactory results from Live Trace on a low-quality image of custom type to the point where I could use it at any serious scale. It fails to capture the nuances of the typeface (because they're not there to capture) and frequently introduces all kinds of other strange-looking artifacts.

It's tough to say without seeing a sample, but I'd think that Live Trace is unfortunately pretty unlikely to work acceptably on a text-heavy document -- but as you mention, OCR is a very viable option.

I'm a green hand on this problem.
But I found an OCR component on the web. I want to know the difference between the normal one and this OCR component.
It is said that it is a professional tool that could be re-edited online according to your pwn requirements.
Did it help?



Sincerely,
Arron
