but when I open up an existing project in Premiere I can't get smooth playback in the timeline anymore it freezes after only a few seconds of playback. Wasn't like that before.

I haven't used MLVFS for a while now so a few things might have been upgraded, but I encountered this problem you describe with 23.9fps footage and 25fps seemed to be working well...

Timecode starts from zero then counts frames synched with fps. Are you referring to timestamp? Can't check the files atm.

Well on 5d mkIII 1.2.3 I have two timecode options:
rec run, which starts from zero and
free run, which is equal to cam time..

I'm talking about free running, because it's the setting of my choice..
My point is, raw2cdng dng files gets it right and also cam native MOV files gets it right and mlvfs seem to lack this functionality..

Also just noticed that mlvfs does not offer time code?

ok, so the reason I thought mlvfs does not offer timecode was because the first frame is reporting 00:00:00.00 when I'm using free runing timecode, hence it's incorrect!..

and first frame extracted with raw2cdng has a timecode of 15:47:12.0 which is a correct timecode!

Nope. I have to take a look at DNGs produced by raw2dng.

I don't even know how raw2dng does (as you say) 16 bit maximization - really converts values to 16 bit (black/white will be also affected) or just unpacks them to 16 bit word.

I wish I could understand that code or the theory behind it, but I'm sure you could see how it's done here: https://bitbucket.org/chmee/raw2cdng

yeah, sorry it's raw2cng, not mlv.. Tried 3 methods to access dngs on that same 23.976 file and can confirm that both mlvfs virtual cdngs and cdngs extracted to a drive are stuttering and are impossible to work with, overal cpu load is *only* 18%.. Now using extracted dngs wit raw2cdng (16bit maximised) procesor load goes up to ~40% and it's playing back normally..

@bouncyball, any idea why is this happening??

Nope nothing particular, raw2cdng (there is no mlv2cdng AFAIK) extracts phisical cdng files and writes to disk. MLVFS shows virtual dng files and sure has an overhead on CPU. You can just copy dng files from MLVFS virtual dirs to phisical disk and try opening them in NLE (23,976 ones).

@voblaunsane
Hardware is ok exept hdd maybe. There is no difference between 24/23.976 and 25 FPS for MLVFS. It does not care about FPS at all. What cares about it is the NLE while processing cinema DNGs (adobe premiere as I understand in this case). I never had this kind of stutter under windows with premiere/davinci resollve even on the less powerful hardware than you've got (note: I used SSD)

I've tried all sorts of things and now can not be 100% certain, but I believe to have tried extracting cdngs with mlvfs and mlv2cdng with only later rendering normal results and that precisely makes me think the problem lies within mlvfs.

I'll be able to do some more tests and confirm this next week. Is there any particular facet of this you would be interested in, @bouncyball??

What is your hardware?

My hardware is good enough to handle 25fps footage with absolutely no problems, but 23.9fps is not possible to edit..it's lagging, stuttering, etc..

Before you blame it on hardware please examine following piece of evidence: graphs showing resource usage by mlvfs process

Quote from: voblaunsane on June 03, 2017, 07:08:50 PM

25 fps graph looks nice: constant load on hdd, processor cruncing numbers, works lika a charm and the whole take can be previewed in a blink


while 23.9 fps is a real mess: hdd constantly choking and processor is having a nap, visual performance - stuck on one frame mostly...


It looks like working with 23.9, mlvfs is not utilising resources properly...


Now to answer your question:

What is this ? Can someone explain bouncyball's  MLVFS !
sorry for not being clear enough.. mlvfs.exe (2017-05-06) https://bitbucket.org/bouncyball/mlv-tools/downloads/

<...> as it work flawlessly as is .
do you not experience problems with 23.9fps on PC?



It appears I might be but a singleton...

so I've tested bouncyball's version of mlvfs (with dokan 1.0.3) as it seems to be the latest mlvfs compile out there and still have 23.9 fps stuttering issue..

to demonstrate I would like to share Performance Monitor graphs produced while scrubbing ~3 minute long footate in Premiere

25 fps graph looks nice: constant load on hdd, processor cruncing numbers, works lika a charm and the whole take can be previewed in a blink


while 23.9 fps is a real mess: hdd constantly choking and processor is having a nap, visual performance - stuck on one frame mostly...



anyone else experienceing this?.. I find this is the case with all versions of mlvfs I found out there...

Hi all,

It's been a while since I used mlvfs and now that I have fresh windows and reinstalled everything, took me a while to get this beast running..

Anyway, I am experiencing a massive stutter and general performance issue with 23.9 footage to the point where it is hardly possible to edit. I reported this long ago and someone found a timecode problem. I was under impression this was fixed and I think I was using it with no problems at some point..err..or maybe I'm dreaming? hahaha..

Or maybe using a wrong build or something..here how I got it working:

1. Installed Dokan 1.0.3.1000 (x64) from https://github.com/dokan-dev/dokany/releases/tag/v1.0.3

2. Unzipped MLVFS_x64.zip from http://www.magiclantern.fm/modules/modules/MLVFS_x64.zip/

3. Unzipped optimized.zip to MLVFS_x64 folder and renamed files adding "_opt" from http://www.magiclantern.fm/modules/modules/mlvfs_optimized.zip/

4. Renamed dokanfuse1.dll (in MLVFS_x64 folder) to dokanfuse.dll and dokan1.dll to dokan.dll

I tried all (mlvfs_x64.exe, mlvfs_x64_avx.exe, mlvfs_x64_opt.exe and mlvfs_x64_avx_opt.exe) and finaly capitalised on using mlvfs_x64_avx_opt.exe which seemed to be the fastest (super subjective/based on feeling)


all the settings on localhost panel are set to off, disabled, default or none (default values)

Same issues occur with footage copied from mlvfs drive onto HDD;
Yet unpacked using raw2cdng 1.7.5 works really well, not using mlvfs that is;

Also 25fps with mlvfs works like a charm too..


Thanks a ton! Good night..

if you extract the files using mlvfs and let premiere work on the extracted files, does that work?

no. same issues with 23.976. Works fine, same as on the fly with 25fps..

Using mounted 23.976 material renders always fail at a particular stage, until I drag the clip to another sequence, then it gets a new fail point. More often then not fail point is 99%.. The extract from mlvfs, even in new sequence, always fails at the similar point.. but same material extracted again, gets a new fail point .. makes sense?

Also caught the exception, actually all 6 of them, but was running many tests and can not reproduce, here's the log: https://drive.google.com/file/d/0Bzfm11RAqkBzb0xwbHpTT3JqSEE/view?usp=sharing
#14
Found a few things here:

1. Finally I managed to render mlvfs on premiere! I found that 25fps material works flawlessly at a lighting speed, when 23.976fps is impossible to scrub and it doesn't render "error compiling movie. unknown error"... when that same 23.976fps mlv, extracted with raw2cdng works just fine. Any ideas?

I logged the activity with separately mounted differing fps files here: https://drive.google.com/file/d/0Bzfm11RAqkBzN0dnV05kMGpmSms/view?usp=sharing

2. Mounting a full CF results in empty mlv folders. localhost:8000 reports 0 frames in files found. Freeing some space resolves the issue. It could be nice have mlvfs reporting "not enough disk space".. Otherwise it gives the impression that files are damaged..

Thanks!

can you check if the file with vidf errors reads fine using mlv_dump?
can you run mlvfs.exe with parameter -d and upload the whole log? (append "> log.txt" to log into a file)

Thanks!

I tried all combinations of commands I could've possibly ran, alas was unable to reproduce, very strange because I received those all first day of use and then next day it was gone like nothing ever happened! Also deleted the files before reading you post, aww..

Yet main issue being unable to render persists! So I ran mlvfs with -d 2>log.txt mounting a folder with one sequence (3 files mlv/m00/idx), created new premiere project, located sequence in media browser, dropped it straight on the timeline and hit render.  This produced "error compiling movie. unknown error" and 54.6MB logfile here: https://drive.google.com/file/d/0Bzfm11RAqkBzaXgzOTUwQ1dIYUU/view?usp=sharing. Not knowing what I'm looking for tried to do some detective work and the following seems to be all over the place: CreateFile status = 0 - lastError = 2

This mlv was recorded with no sound, but I see the following in report alot.
CreateFile : \M04-1513.MLV\M04-1513.wav

I left an instance of mlvfs with -d running while typing this post, new log file is nearly 2GB - I'm scared :)
#16
any idea about the unhandheld (haha, sorry/not sorry) exceptions and errors reading frame headers, which I am guessing are the causes of problematic handling by premiere?...

I've described those few posts above..
http://www.magiclantern.fm/forum/index.php?topic=13152.msg163728#msg163728

Please let me know if there is any troubleshooting or testing I could do in helping to improve it!

Thanks.

Hi all,

I love the concept, but I cant get Premiere CC to properly deal with the files. After importing the sequence, scrubbing works nowhere (media bowser/bins/timeline), hence I initialy thought it does not work at all, BUT it plays back with no problem after a pausing a moment. Mind you that I have no such problems with dng extracted using raw2cdng 1.7.4

Alas, the biggest issue remains rendering, where I get "error compiling movie. unknown error" and therefore being unable to export at all! Again, this does not occur with dng's extracted with raw2cdng 1.7.4.. Here's what I get in console after export attempt:

H:\DCIM\100EOS5D/M04-1511.MLV: Error reading frame headers: vidf block for frame 0 was not found
H:\DCIM\100EOS5D/M04-1511.MLV: Error reading frame headers: vidf block for frame 0 was not found

I'm running this on Win7 SP1


Context Menu for Win

I would also like to make a small contribution to windows users adding a context menu option "Mount with MLVFS" to your folders. Technically registry entry only should suffice, but I found that webGUI loads blank and console outputs fopen errors without setting command path to mlvfs folder of residence before executing, hence the bat file..
Obviously, you'll have to change paths to suit your requirements.

mlvfs.reg (execute this file to add context menu option for your folders):
Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\shell\MLVFS]
@="Mount with MLVFS"

[HKEY_CLASSES_ROOT\Directory\shell\MLVFS\command]
@="\"C:\\Program Files (x86)\\MLVFS_x86\\mlvfs.bat\" \"%1\""


mlvfs.bat (place this next to mlvfs.exe)
@echo off
c:
cd "c:\Program Files (x86)\MLVFS_x86"
mlvfs.exe x:\ --mlv_dir=%1
#19
ups, webgui doesnt work that way for some reason.

FIX: mlvfs.reg (execute this):
Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\shell\MLVFS]
@="Mount with MLVFS"

[HKEY_CLASSES_ROOT\Directory\shell\MLVFS\command]
@="\"C:\\Program Files (x86)\\MLVFS_x86\\mlvfs.bat\" \"%1\""


mlvfs.bat (put in a folder with mlvfs.exe):
@echo off
C:
cd "C:\Program Files (x86)\MLVFS_x86"
mlvfs.exe x:\ --mlv_dir=%1

Since it seems you know your way around Windows scripting, one thing you might could do to help is that MLVFS for Windows needs a user friendly way to be launched (like the Mac version which uses an 'Automator' service for launching it). I was thinking a bat file that could be added as some kind of folder action via the registry (I think that is possible, at least for files, not sure about folders) to show up in the right click menu. That way you could just right click on a folder and see "Launch MLVFS Here" or something like that and it would startup MLVFS for that folder in the next available drive letter.

Make a *.reg file paste the following:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\shell\MLVFS]
@="Mount with MLVFS"

[HKEY_CLASSES_ROOT\Directory\shell\MLVFS\command]
@="\"C:\\Program Files (x86)\\MLVFS_x86\\mlvfs.exe\" D:\\MOUNT_POINT --mlv_dir=\"%1\""


you'll have to change
\"C:\\Program Files (x86)\\MLVFS_x86\\mlvfs.exe\" to where ever your mlvfs.exe is located and
D:\\MOUNT_POINT empty folder to mount your files to..will also need to be surrounded with \" if you use path with spaces..

once you're done, execute this file and context menu should appear with "Mount with MLVFS" option on every folder you right click..

what puzzles me though is why formatting exFAT SD in camera still results in exFAT, but formatting exFAT CF in camera returns FAT32...

Hi,

This would be lovely to have. Say something similar to crop marks, where you can produce an image to tell the ML how to display corresponding luminance values.
Is this currently hard coded?

Thanks,

Hi,

would it be possible to have cards formatted exFAT in camera?

formatting SD 16gb exFAT with 550d returns FAT32; Not a big deal..

formatting SD 64gb exFAT with 5dIII 1.2.3 returns exFAT; YES!

formatting CF 64gb exFAT with 5dIII 1.2.3 returns FAT32; Booooo!

Thanks!

Hi,

Adapters for older lenses have chips with signature usually f1.4 50mm. Would camera by any chance be able to overwrite it?

I have this feeling in my gut that it's highly unlikely, but would be really cool feature to edit lens name, focal length and aperture.

Cheers,
Vobla
