aha, thanks for claryfing this. I,ll stick to my virtual box for now. Thanks for helping out

for the card spanning users:
can you reduce CF only buffers to 1 or 2 and play with the buffering method?
maybe this will help. method 3 or 4 was the most reliable for my setup.

kgv5 · « **Reply #802 on:** November 12, 2013, 09:53:00 PM »

Tried CF only buffers 1 and 2 (also combined with all buffer fill methods), 1 seems to be a little bit better (10-15 sec more) than 3 or 4 but still far from performance from the beginning. With 2,5k 2,35:1 i am getting 35-45 sec (23,976). Ah.. and it seems that "expected frames" and color buffer graph also doesnt work properly - because it skips frames when theoretically recording should last longer.

g3gg0 · « **Reply #803 on:** November 12, 2013, 10:25:35 PM »

yeah it's possible that the estimation isnt that acurate.

how are your data rates when you enable spanning and the camera barely shows a continuos OK?

kgv5 · « **Reply #804 on:** November 12, 2013, 10:34:34 PM »

108-109 MB/s in total. When it shows about 108,5 it estimates 2500-3500 frames but after 35-45sec suddenly decreases and frame skips when shows 800-1200.

EDIT: Could we have a 2240 horizontal resolution as it is in raw_rec? I have just noticed, that in raw rec we have 1920,2048, 2240, 2560, 2880 etc, mlv_rec has 1920, 2048, 2560, 2880.
2240 is missing and this res could give decent frame number in 16:9 with good margins for post stabilization. thanks

This means that the binary is not for your processor

Thanks for all the help by the way.
I'm getting the same message "cannot execute binary file"
would the MLV_dump work if I use terminal on say, another macintosh running an older version of OS X?

or would I have to use a windows machine?

are there any alternatives to converting MLV files? I've seen many videos online that show how people convert and edit their files, but it seems they leave out the mlv_dumping part and their files are already RAW..

Again, thanks for the insight and I appreciate all the tips I can get from you. I'm just eager to start editing the raw footage or "MLV" footage I shot..

Link :Watch on youtube

its working on a 2008 mac book pro running OSX Mavericks

cd desktop was to navigate to my desktop
cd mlv was to bring it to the mlv folder inside desktop

do note mlv_dump is in the same folder (idk if its necessary)

You should probably try it on a different PC. I had the binary error while in the VM.

mlv_dump has this useful option:

Code: [Select]

-f frames stop after that number of frames
Is it possible to integrate another option:

Code: [Select]

begin with frame number x and stop after frame number y

good point, will add.

What information do you need in order to diagnose an issue? I have found a frame with a weird border and it's happened a couple of times now while using MLV_REC.MO. Want to ensure any bugs I submit have all relevant information so as to not waste any time.

g3gg0 · « **Reply #810 on:** November 21, 2013, 09:53:02 AM »

what do you mean with weird border?

Cypressentgrp.com · « **Reply #811 on:** November 22, 2013, 07:03:47 AM »

I need help converting my MLV's, I was blindsided by this, I Bought a 7d and spent hours digging through threads trying to find the latest nightly build so i could go shoot raw, well just got back and a discovered I shot everything in this MLV format, which sounds great, but I can't process the files

Im on a mac and I was hoping for a little guidance, the info is speed all over this form, I gather what MLV is and I have the mlv_dumper and that i need to use terminal but just not working for me

RenatoPhoto · « **Reply #812 on:** November 22, 2013, 01:36:54 PM »

Did you see the video above?

And also this?

g3gg0 · « **Reply #813 on:** November 22, 2013, 01:58:26 PM »

in this video he blindly entered "<filename.mlv>".. correct would be "filename.mlv" of course

i didnt expect that someone really doesnt understand the common computer syntax for obligatory parameters

Yes I did, I did not work, " invalid Instruction 4 " or something to that effect, It seems the binary doesn't work on my mac. I've tried both the dumper and the mlv2dng. Nether worked on this mac. It seems I have no way to process these files. Total bummer. Even tried that app, want work on 10.7.5

Get yourself a virtualmachine for windows

I see your commit. ThankYou for adding

you are welcome.
can you test it thoroughly?

escho · « **Reply #818 on:** November 23, 2013, 06:49:05 PM »

I tested all possibilities. It runs fine.

But I noticed a 0 Byte-file:

Code: [Select]

What is this file for? This file appeares without the f-option, too.

dubzeebass · « **Reply #819 on:** November 23, 2013, 07:09:07 PM »

Question: do we have any way of extracting just the metadata per frame to a file so that my shot logs can leave out the ISO/shutter/aperture information, and follow focus/zoom etc?

I've tried extracting just the metadata but it comes out as that 0 byte file.

g3gg0 · « **Reply #820 on:** November 23, 2013, 09:01:28 PM »

./mlv_dump -m -o meta.mlv in.mlv
after that you can dump all metadata with
./mlv_dump -v meta.mlv

doesnt that work?

thanks a lot.
that sparse file should be gone now.

escho · « **Reply #822 on:** November 23, 2013, 09:30:42 PM »

OK! Has gone.

Another thing: bad pixel remooving

I tested the bad-pixel remooving from cr2hdr with normal dngs, extracted from a raw-video-clip with raw2dng. To be able in doing so, I fooled the hdr_check in cr2hdr and looked at the debug-output-dngs: All the bad pixels are remooved! That´s really great!

Can this function be ported to mlv_dump in some way?

Edgar

can anyone please post a link with the current mlv_dump version for mac
thx
