Magic Lantern (RAW) Video format v2.0 (mlv_rec.mo)

[zachnfine]

And just like that, after I pulled the files from the CF card to hard drive and deleted them, it's skipping frames again, still formatted to FAT32.

I guess I'll shoot with the normal raw video and second system sound at a shoot this afternoon, then I'll get back to trying to make mlv2.0 work for me later. It's very exciting that sound recording has been made possible! I'm thinking even a scratch track at 8-bit 22kHz could be used to automatically sync up the second system audio later (pluraleyes/fcpx/etc).

updated mlv_dump to skip WBGain information when writing to DNG

I shot a full 12 mins @ 1920x1080 with sound on a 5D3 with the 64gb KomputerBay 1000x card in a test.  Maybe this isn't new information, but I was reading that people were having issues with skipping… I didn't lose sync once.

*It is important to note, however, in a previous attempt with the sync beep on (which didn't sound at rec start) there was NO recorded audio when I processed the clip.

I'm not sure if ALL of these settings make a difference… but maybe it'll help trace down the issue.

I do think it is important to note that with sync beep on, several times my first frame has been garbled and no audio was recorded, despite mlv sound being on.

Warm up your card and set picture quality to jpg not raw.
I get continuous woth 24fps 1920x1080 with sound and continuous with 25fps after warmed up card

Ok, I compiled new mlv_dump.exe and now MLBrowser exports dng with WB Temperature 5500 and Tint +19.
Thanks

tried 5 times I did get 1at 3mins also dave are you still getting .M00 files also?

everytime the file needs to break pass the 4GB size thats when it starts.

[zachnfine]

Set picture quality to jpeg? You mean in the normal Canon menu? Does that affect video recording for some reason with mlv_rec when it doesn't seem to have an impact on raw_rec?

[kgv5]

   - memory hack -off
   - extra hacks - on
 

Are you sure, that memory hack shouldnt be ON?

Yep, I'm still getting .m00 files, but I am not (nor did I ever) have an issue with them splitting. 

[AnotherDave]

Should it be? I don't know.  It isn't in my setup and it is working.

anotherdave,
    whats your allocation unit size on your KB cards ?

[g3gg0]

the first 4GiB are saved in a .mlv, the next in a .m00, the next in .m01 and so on.

memory hack on 5D3 gives you some extra buffers

anotherdave,

I donno… how do I find that out?

[Jakobmen]

When you format card it should tell you

@g3ggo

used MLV dec 29 and ML dec 30.

I can achieve continuous ok MLV with Sound On with the ff resolutions;

1728 x 972 16:9

1856 x 928 2:1

they can record 15 min in a 64 gig 1000X KB card.
tested with clapper at regular intervals to test for audio sync. -No problems with sync.

1872 x 936 - starts to skip after 8 min.

tested FPS over ride with sound- I find this nice as it will work. MLV Sound is recorded in real time.
This can be used in certain situations.

I had a minor problem when the framing guides and other info turns OFF when recording and found out that

DISABLE G. DRAW needs to be ON to keep the frame guides and other overlays on Screen.

I suggest this be RENAMED as its description and name does the Opposite and got me misled.

Also, using certain screen layouts, the buffer graphics/elapsed time/frames/datarate info that comes on during record
clashes with the overlays such as vu meters, lens info framing guide etc.
Using 16:10 HDMI t/b layout scheme will help avoid this.

On using ext HDMI monitor.- I get short record times and coruppted frames with hdmi attached.

1728 x 972 GD.OFF + hdmi monitor = 28 sec only then skips and stops.
1856 x 928 GD.OFF + hdmi monitor = 35 sec only then skips and stops has corrupt frames.

whats everyones Allocation unit size on there KB 64gb 1000 cf cards?

thanks for the feedback!

[Jason Montalvo]

Finished a shoot yesterday and recorded using mlv_rec . Some of the takes were longer and over 4gb in size where ML split them into .m00 .m01 etc. Every time I open MLV browse sharp and navigate to the folder where the files are located it quits. Any pointers from anyone ?

I also noted that some of the clips are 4.29gb in size FYI card is exfat formatted.

Thanks !
