[request] batch-convert options

[xnview]

1: encode source file with desired settings
2: compare file sizes of encoded and source
3.1: encoded filesize < source filesize:
place source to bin if it's larger and place encoded file in source folder
3.2: encoded filesize >= source filesize:

So when you use same format for input/output file, right?

So when you use same format for input/output file, right?

Coding to simply compare the size of each output file with the size of the processed input file, without checking the output format, would meet the requirement, and also allow file size comparison when the output format is different if that is useful, wouldn't it?

As all output files always have the same extension, that should meet the requirement and give an additional option at no cost?

[gendalf]

@xnview, should work regardless of input/output format (like when converting a folder with a bunch of random .png, .jpeg, .webp to 95% .webp) or conditional filters (like resize to 4000 width, if width>4000 ).

See issue for current status and some details.

+1 Good idea!

[xnview]

This problem is supposed to be fixed in XnView MP 1.6.0. Please check and confirm the bug fix here.

@xnview,
1. Conflicts with the "delete original" option, as I don't need it to delete the original - if it's smaller than converted, and I don't need it to keep 2 of each images of a downsized image (should work with delete original on, therefore keeping the original number of unique files).
2. Doesn't work at all with filters on (conditional action, like resize).

As it's an experimental feature, currently 'delete original' doesn't work with it...

Yes, i don't know what to make. If you want to resize or adjust, do i need to keep original one??

@xnview, 2. Compare end-result (after application of conditional filters and after conversion) to original, then it's the same logic:
- keep original if it is still smaller (without saving the converted&resized).
- otherwise keep converted&resized, while deleting original.

Yes, but even if user add multiple actions?

[gendalf]

@xnview, the goal is size reduction, so the comparison should be the last automated decision making check for which file to keep - converted&resized&whatever or old. Otherwise you'd just not have the option ticked (default) in the first place.

I think you are trying to fit your VERY specific workflow into single setting.

core functionality of this feature should only affect result file (depends on comparison):
- keep encoded version OR
- replace it with a copy of the original

then there will be no any conflicts with
- delete original setting
- overwrite original if you choose same folder/filename

@xnview,
2. Doesn't work at all with filters on (conditional action, like resize).

Technically it's possible, but logically it doesn't make sense to me yet.
If I add a filter, I want it to be applied regardless of the result file size.

At this point, I can only identify 2 reasonable uses:
- convert multiformat input into single format
- resaving same format with differect settings

[gendalf]

If I add a filter, I want it to be applied regardless of the result file size.

This option compares: ?end result < original? and keeps original or the end result. Filters 'might' assist in reducing the filesize, but not always (for example original might be low quality already or the conditional resize for current file isn't significant enough), but ultimately, this option should be the decision-maker for the end result, after both filters and conversion applied.

If you just want the conditional filters applied to everything (or no filters, simple conversion), then don't tick the "only keep smallest size file" option, as I've mentioned above, and use the program as if this option doesn't exist, or run it twice

[user0]

It seems like "file size" is the only success criteria and you don't really care about "image quality/size", it's strange tbh.

But so far, the only part I disagree with is that new setting shall REPLACE original file (as far as I understand you).
It shall only work with target folder and COPY original there (depends on size comparison). Of cause, if source and target folder/filenames are the same - originals will be replaced.
Then you go and manually delete original folder if you do not need originals anymore.

However, to fully understand your needs, can you provide:
- few example pairs, eg 1_source, 1_result, etc (result with filter applied as well)
- filter(s) settings
- target format(s) encoder settings (if differs from default)

[xnview]

Should be ignored or copied?

From another user

rather than "keep", it will actually "copy" the original file
