[deprecated] MLV Viewer to view .mlv (and .raw) files on windows (C#)

[bouncyball]

its harder to not play the video than to play it
which frame should i display? at which brightness?

let me play a bit, maybe i can find a good answer.

ok

Regarding the frame to display - 1st frame I  think will be fine with playback mode activated on focus (or maybe not) and FF/REW by mouse drag already is a cool feature. I think this last one should be smoother with all of the playing off.

Brightness? don't know you tell me.

updated browser.
 - added metadata display (popup)
 - experimental grouping (looks ugly)
 - changed autoplay behavior

Hi, how to delete a raw file in the camera? thanks

[g3gg0]

until now, using the file manager module. but this thread is about a PC tool.

I really like the MLVBrowseSharp, what a time saver,
These tools get better and better all the time

nice to hear

updated binaries again.

 - added preview resizing
 - non-selected previews animate up to frame 10, then they stop
 - grouping works a bit better now, but still the last group gets the maximum size that the window would have if you make it narrow.

this is some sort of windows form issue i dont really understand. i dont calculate the sizes on my own, i configure the controls to do that for me, but not very successful as you can see
i also know that it may behave wrong if you change the directory after grouping.

another small update to fix some small scrolling bug

[bouncyball]

Hi !

Great additions. Grouping feature is cool!
I noticed that after picking another file preview every clip advances 1 frame further. Is it supposed to be this way?

nope, its a bug
just not that important to fix imho

I need some more information to be showed in mlv_viewer:

- how many frames has the video
- which frame(number) is actually played

Can this be added to mlv_viewer for both, mlv and raw input files?

Edgar

[g3gg0]

updated, can you test?

[g3gg0]

fixed

Tested. Exactly, what I need for my recordings of the ISS (with  a focal lenght of 2000mm). Great!

ThankYou!

want to see footage and results

If you want to see a result, then look here (it´s in german):

Source was a 2.5G RAW-Video with my 600D, a 10´´ RC-Teleskop and a 1.4x TK. All in all 2800mm focal lenght.
It did the tracking of ISS manually. With your mlv_viewer it´s now easy to lokate the very few frames (maybe 50 of 4500), where I can see the ISS.

really cool shots.
why do you think that with normal video the noise would be better?
denoising is smth that can be done in post much better.

if you used the zoomed mode, then you should get a 1:1 sensor dump iirc (never tried)

[escho]

The 600D with high ISO means much noise and  bunch of big badpixels, if I use RAW-Video. Especially, if the clip is underexposed, which I cannot avoid on ISS. A mov-file is fine here, regarding noise. But not only noise and the badpixels go away with mov, the details dissapear too.

I did a lot of tests and decided for me to use ML-RAW (mlv) and a 1:1 sensordump for getting out as much as details as possible. The noise can be handled, but the badpixels make me crazy. Depending on what I shoot, I work with the highest possible resolution and low fps (moon) or with high fps and low resolution (planets and satellit).

I do not want to hijack this thread with my astronomical stuff. So I finish here. Only one more thing. Some time ago I compared raw-video against mov on saturn. raw-video did win . I can show the link to my (german) photo forum, where I uploaded the pics. But you would have to sign in for regarding.

i made some usability and visualization updates.

[escho]

I played a couple of hours for trying to compile the mlv viewer from sources. Never compiled C# before. And what shall I say? I did succeed  .
But here a little question:
What is this Lookup.cs for, which is in the projectfile but not in the sources?

Edgar

[g3gg0]

ah ok. tried to set up a lookup table for faster processing. (esp. in-camera speedup)
but didnt find the ideal combination of per-channel index bit depth and image quality.

so just remove it from the project.

[g3gg0]

update:
 - supports MLV Audio playback
   slow frame rates will cause laggy playback, you can disable video for speedup using right-click context menu

[g3gg0]

added an EXPORT function to MLV Browser.
you now can export single (just right-click the selected file) or multiple .mlv files (CTRL-click some files, then right-click any) as .raw or .dng plus its .wav.

it will just call mlv_dump which has to be in the same directory as MLVBrowseSharp.exe.
should work on any OS if you place the mlv_dump there. (to be verified)

[ted ramasola]

g3ggo,

I haven't been abreast with mlv updates lately, only with rawrec, I'd like to ask if the progress in audio recording using mlv is also meant to work with the mkII?
