The one where you got batch_mlv_in-out from. Try pasting in search.

Is there any way I could save only odd or even frames out from an input MLV file and output that into a new MLV file?

I need to do this to save some space of redundant duplicated frames of some MLV written by mlv_rec.mo that wrote duplicated frames in 1fps frame override mode in 1x crop on 5D2.

I tried -f switch but that only allows input of frame or frame range, not comma delimited frame numbers, -f 0,2,4,6,8 for example.

Any ideas would be appreciated. Thanks!

Yeah... unfortunately this is not supported by mlv_dump directly (MLV -> MLV).

What's wrong with exporting DNGs and just picking the needed ones?

Nothing wrong with it, that's what I did. It is just that I would usually keep the source MLV, just in case in I need to re-dump the MLV with a newer/better mlv_dump with improved vertical banding removal, etc. maybe who knows.

[bouncyball]

I understand your point.

But IMHO the better way to fix this with mlv_rec.mo to not duplicate frames when fps = 1. Implementing something like even or odd only frame saving is not that hard but barely widely usable, despite duplicates can turn out be like: 01010111010100 (given that 0 and 1 are frames) this requires picking not only odd/even frames and will be even more work for developer .

How about -f "frameslist.csv" ?
make the -f switch when referencing a user generated .csv to only include those frames listed in it.

This should be done in the mlv_dump code not in the code I added, so maybe you will try to ask g3gg0 b/c this proggie is his exclusive child

[g3gg0]

this proggie is his exclusive child

not correct
accepting pull requests if they fit in cleanly.
and such addition sounds if it can be done in a clean way.

[bouncyball]

not correct

Well... right . Sorry about being too lazy.

@g3gg0: BTW could this be done with mlv_dump's LUA scripting feature?

[g3gg0]

yeah good point. could be done, have to check this.
maybe we have to add a callback but no big issue.

Thanks bouncyball & g3gg0  looking forward to the feature addition.

most of this is over my head but i thought it my be useful for others.
No sure if it's just my test .mlv that's the problem , wondering if any one else has had a   "Win32 Expceptions"

[bouncyball]

Is that exception happens when just running the binary or if you specify some switched to do some job?

Please post exact CLI command and exact MLV you used.
