Some pictures edited in XnView are incompatible with...

Post by Dreamer »

Some pictures (not only) from Panasonic TZ5, pictures edited in XnView, compressed, resized, or cropped in XnView / XnView Shell Extension are "incompatible" with Panasonic DVD recorder, and/or Sony Ericsson cell phone.

In cell phone some pictures have bad orientation, or they are missing completely - mostly if EXIF thumbnail is rebuild or removed, some can't be zoomed at all. In DVD recorder original pictures from digital camera were OK, but after compression and resize in XnView batch processing they can't be viewed, only thumbnails are viewable.

Is it possible to ensure 100% (or maximum) compatibility with all (or most) such devices somehow? By changing some JPEG compress options, removing EXIF, IPTC completely, using specified resolutions only...

Some (downloaded) pictures are OK in cell phone and DVD recorder, why? If you need few samples, please let me know.

Thanks.

There are three ways of saving JPGs:
1. Baseline
2. Baseline Optimized (in Photoshop - I'm not sure how it differs from Baseline)
3. Progressive - essentially designed for the dark days before broadband. The image is built in 'layers' so thet users of slow lines would see it appear gradually 'all over' instead of very slowly from top to bottom.
Image editors usually give you a choice of JPG format. I don't know of anything which lumbers you with Progressive, like it or not

Generally, DVD players will not read (3). I don't know about (2), but are happy with (1).

I'm not sure if the pictures on DVD are progressive, I'll try do burn few pictures as progressive and few as "Baseline" (XnView has just one option progressive on/off AFAIK), thank you for the hint.

Thanks. It's 5 years already?!! :o

Thank you for your kind words, Clo, Helmut!

Back on topic...

Results of my test:

Pictures tested from these cameras (camera - model):

8M 3X Digital CAM - ADVMP82
Canon - Canon PowerShot A550
EASTMAN KODAK COMPANY - KODAK EASYSHARE M763 DIGITAL CAMERA
FUJIFILM - FinePix S5800 S800
NIKON - COOLPIX L4
OLYMPUS OPTICAL CO.,LTD - C700UZ
Panasonic - DMC-TZ5
TECHNIKA - SH-Z625

Thumbnails are the thumbnails on DVD recorder menu, pictures means if the pictures can be viewed in fullscreen on DVD recorder.

Original pictures: thumbnails OK*, pictures OK*
Compressed as progressive: no thumbnails, no pictures
Compressed as "non-progressive": thumbnails OK, but no pictures

* - except OLYMPUS camera, it's probably very old camera, the only without EXIF date taken info

This is strange, something else has been changed probably, some option which caused incompatibility, do you have an idea which one? AR is the same, resolution is changed but it's multiple of 32, JPEG version is the same (1.1)...

You only load and save the file with XnView?

Right, just load pictures, batch convert in XnView*, burn to DVD and view in DVD recorder.

* using the script with these options:

Code: Select all

resize( 1 lanczos 1920 1440 0 1 0 )
settings( 2 0 1 0 0 1 )
output_path( $\Converted )
output( jpeg 75 0 0 2 2 0 0 )
Perhaps one of these options cause that problem, but I don't know which it could be. :(

And if you load & save only the picture? Try to disable the thumbnail create option?

Don't know, but in this case I'd use the same settings as in script I think.
Try to disable the thumbnail create option?
Do you mean "Rebuild embedded thumbnail"? If so, I think it was disabled already, but I'll try again.

I'll try both ASAP, thanks.

OK, results...

- only saved - thumbs OK, no pictures
- also resized, rebuild thumb option disabled - thumbs OK, no pictures
- also resized, rebuild thumb option disabled, keep EXIF disabled subsampling factor default - no thumbs, pictures OK!!
- also resized, rebuild thumb option disabled, keep EXIF disabled subsampling factor 4:2:2- no thumbs, pictures OK!!

So it's probably the subsampling factor option, I'll try to enable "keep EXIF", then also thubbs should be OK, but which option has better quality, "default" or "4:2:2"?

Thanks.

Edit2: Confirmed, it was the subsampling factor option "best quality"! Best is not alway the best. :) When using 4:2:2 or Default it works good. Picture must contain EXIF thumbnail, otherwise thumb is missing also in DVD recorder/player(?) menu.

BTW Pictures from Olympus are OK too, only thumbnail is missing, probably because this camera doesn't contain any EXIF thumbnail, also "Orientation" item is missing in EXIF.

So the problem is resolved, thank you!
