[WINDOWS] MLV to DNG Batch Converter v1.9

[tonybeccar]

1.9 works good Tony.

Its just that it looks for FORMAT.dll all the time, I already downloaded previously from its site and upon first run I pointed the app to the tools folder. Did I do that right? How can I fix this?

Format.dll? I think that's irfan view problem.. did it work before for you? Did you point to the original irfan view folder? Anyway in next release will abandon irfan view as it is really unconfortable to do that!

Anyone else with this problem?

yup.. i just ignore it now =(

[tonybeccar]

Wow.. really? Weird.. I assume it gives the problem whenever you click a file in the list and tries to load the thumbnail right?

yes sir

[tonybeccar]

yes sir

Ok will look into it.. strange is not happening to me.

i just processed two dual iso clips, both of them had flicker, one more than the other but noticable in both of them, not acceptable for pro work, bummer, is there some parameter i can change in order to eliminate flicker?

thx in advance

cheers!

currently uploading both, i'll post them as soon as they're up

Mmmm I have no idea about that.. what the program does is execute cr2hdr with all the default settings.. maybe something to look up in the dual iso thread.. I have no idea about that.. I have a 7D so no dual iso video... I have one clip of a 5D3 that I did the test on.. 116 frames and I didnt processed it completely hehe, so I don't know about the flicker.

The other settings you have basically start lowering the quality, like the interpolation, process in full res.. so I don't know about the flicker really...

I made some tests and dualISO works completely fine Thanks Tony for implementing this Flickering is the matter of further processing (shadow/highlight recovery) and has nothing to do with "unpacking" and cr2hdr.
Tony, do you think it would be possible that your app could recognize dualiso files among dozens of normal MLVs? That would be the huge time saver as well.
Cheers

look this is what i got:

both rendered through resolve, do you think flickering is because of the amount of highlight recovery i made in resolve?

cheers

I'm trying to figure out a way to automatically detect it.. but for now not too sure. Will keep you posted!

I see the flicker.. it's small.. I have no idea really. The videos look damn great that for sure!

I'll try to fix it in cr2hdr (most likely I will add a command-line switch called --video).

Not yet sure if I'll use the post deflicker algorithm or I'll simply force black/white levels and ISO match curve to be the same for all frames.

v1.9 is out!

- Back to mlv_dump cause of the "mlv2dng stopped working" error. It's a pity cause it was SO fast.
- Interface improvements, with bigger queue and saving space on options.
- DUAL ISO SUPPORT! Though it is sooooooooo slow. But anyway I think that's the way it is. (right click selected items on queue)
- Now you can specify the camera ID for multiple cameras. (right click selected items on queue)
- Chroma smoothing option. Default, none. (may change that?)
- Small bugfixes.

To do, a lot! Including full mlv support, black image substraction, better proxies (using xconvert), dual iso options, full metadata window, more options, delete mlv/dng, import dng folders, proper installer/updater... the list is endless.. hope i can do it all soon! CinemaDNG for me is the most important.. will wait for command line... and I was thinking about Dual ISO and CinemaDNG.. not at all possible right??? That's a complication :/

Cheers!

Thank you very much for the update! \o/

Looking forward to the CinemaDNG support!

And don't forget the pink dot remover, please!

@a1ex, someone had the same issue some days ago, i'm sure it'll be much appreciated if you have a "fix" for this

I was going through the DNG options and here's a comparison between the various DNG compressions: None, Lossless, Lossy


Here are the full-res files:

http://www.image-share.com/upload/2476/179.jpg
http://www.image-share.com/upload/2476/180.jpg

I couldn't find (as expected) any difference between None & Lossless. There's minor difference between None/Lossless & Lossy... in my scenario, it's really really minor... 90% of my friends couldn't tell a difference.
The real difference comes when you process for Lossless or Lossy... it takes forever. Lossless will result in around half of the original (none) files, and Lossy in around 1/4th...
Time to process will vary, but here's a simple one: it took about 2:12min.(None) to process a 2GB spanned MLV, 26:16mins(lossless) & 30mins(lossy)

Hope this is of some use and i don't repeat someone else's comparison...

[chmee]

i'd wonder, if there would be differences between no and lossless dng. thats the advantage of lossless its lossless

as i read, lossy is compressed in 8bit yuv. so look in the bottom right corner, change from blue to white circles. there are significantly more edge-artifacts. if you'd say, you use it as archive-format, ok. but as working-footage, sorry, no.

[arrinkiiii]

as i read, lossy is compressed in 8bit yuv.

...and lossless?

[chmee]

lossless is like zip/rar/lzw, you lose nothing, therefore lossless. its a straight data compression, not a visual one.

[arrinkiiii]

Thanks for the info, glad to know that they stay still with 14 bits.

[jose_ugs]

yep, results in the same quality, but less storage is needed. Only thing is... takes time to compress it. I don't know how it performs in Davinci/AFX compared to non-compressed DNGs in terms of speed

I didn't do an extensive test.. but I tried different compressions in AE and it was the same in terms of speed.. at least I didn't notice one.

how many space do we save? 30% imho the savings are not worth the time it needs. its too easy buying another hdd with 2tb.. if i want to archive the dngs, then i'd do a simple zip-compression on the folders. done. but nonetheless, its now built in and some are thankful for that..

I think 50% with lossless. Indeed it is veryyyy time consuming. But you gotta sleep at night.. hehe..

Looking forward for this fix, i'll test it as soon as its updated.

I don't quite understand the Pink Dot Remover thing yet.. cause I never experienced it. I found this thread: http://www.magiclantern.fm/forum/index.php?topic=6658.0

Is this it? This program that I download from the first post will fix the pink dots for ALL cameras affected by it? I just notices there is a .jar inside, so have no clue.

Anyone can point me in the right direction so I can implement it?
