MLV App - All in one MLV Raw Video Processing App [Windows, Mac and Linux]

[garry23]

Another ouch 

I was only trying to help by providing user feedback.

I truly respect and welcome this development, but will now wait patiently as others develop it according to their needs.

Cheers

Be sure to keep yourself informed. Most of what´s been asked is already to be found, a little search here or even outside this forum sometimes makes wonders. Or keep asking. Maybe good for keeping things alive, who am I to judge...

- Added luminance vs. saturation tool
- Improved quality for HSL tools
- Added TIFF averaged frame export
- Added single frame JPG export
- Some bug fixes and some minor changes

Minimum OS:
- OSX 10.8.5 Mountain Lion

'NNNNNNNice!!!!

Small bug (?) report.

While trying to identify the root cause of these artifacts, I've noticed I'm unable to identify ML version used for the original recording. The sample clip shared there appears to be exported from MLV App, and this is the only VERS block I could find:

Code Select Expand


Block: VERS
  Offset: 0x0000023c
  Number: 8
    Size: 40
    Time: 18446744073709552.000000 ms
  String: 'MLV App version 1.9'


Normally, mlv_rec/mlv_lite are saving extended version info (multiple VERS blocks) about ML core version, alongside with info about modules loaded, including the version of each module.

Based on this, I'd say the preferred way to handle VERS blocks while transcoding is to add the app-specific block on top of existing ones.

@a1ex: Bouncyball was working on a fix for this problem and you could try if it works. It is not yet in the release, but the source is commited to the repos - are you able to compile?

Great!

When we export JPEG's (JPEG200) it seems to spit out one photo per folder. Is this to be expected?

It would be nice if we can export all the photos into a single folder as opposed to one for each folder.

Not sure about answer, but it looks ridiculous

There is already a discussion going on. But work hasn't been started.

Deleting the frame is a bad idea for video, because audio gets out of sync. For the new photo features it maybe makes more sense...

I've got a simple proposition. Let's assume we are searching for bad/pink frames and there are a FEW of them not many. So we can just manually mark them in the mlvapp as such (bad) frames, save this info to some array and use it during export, skipping or duplicating before/after frame or whatever.

There should be a possibility to auto detect frames like this though, with some % accuracy.

Let's assume we are searching for bad/pink frames and there are a FEW of them not many.

4 years ago I've had a 20 days project on 3 TB HDD which got damaged on the last day (full of footage). I didn't get a lot of experience those days, so it was the only copy.
After a month of recovery information in a local company I've got all my footage with a lot of bad frames. I had to manually cut all these frames in Premiere.

There is some open source project with Optical Flow - slowmovideo.granjow.net. Interpolating missing frames may be implementable here too...

This is to be expected. MLVApp is a video tool. Normally a video has many frames and the frames of one clip are sorted into a folder.

@bouncyball: if I remember right, we discussed this in past... that's the way to go.

@histor: optical flow is not always usable, because it just works for debayered picture data: e.g. exporting cdng is RAW and would not be possible then.

Curious how Davinci resolve implements optical flow. Do you know @masc?

One thing i thought of when fixing bad pixels yesterday. Is that i could be a nice feature to be able to mask the fix pixel command. So when u are certain of a specific pixel that you want to fix, u dont have to fix the whole frame affecting the whole image, with calculations that could be faulty, on for example reflections in metal etc.

As masc said, on "debayered picture data"

But I have suggested a while ago, we can try to interpret bayer as 4 channel image, which would allow optical flow on bayer raw. Haven't tried it of course, but that's what they do for neural networks.


Also who noticed the new url?

[bouncyball]

Yes. In case when all MLVs are 1 frame (raw2mlv converted) files. I thought DeafEye was talking about regular MLV exporting to jpeg2000

New URL rocks

[masc]

so who noticed the new url?

GREAT!

New URL rocks

I thought I would let anyone else having the issue with MLVApp1.10 crashing on Windows 10 64, that I've been using the MLVApp 1.10 Win32 version on my Windows 10 64 PC and its been working flawlessly so far.

I really enjoy this program and appreciate everyone's work!
Thanks

[Danne]

Love the simplicity of the new url.. oh so sexy!

I thought I would let anyone else having the issue with MLVApp1.10 crashing on Windows 10 64

Could you be more specific about crashes?
At least:
1. can not be started, crashes imeadiately
2. runs but with random crashes
3. runs but crashes during export
etc...

P.S. Windows 64bit users please report back your experience.

[cmh]

I fired up a fresh install of windows in a vm and tested 1.10 64 bit static real quick. Importing, moving some sliders, exporting and it didn't crash.
