Hi Team,

I have a corrupted MLV wich only extract partially 1/3rd of it's DNG. The message using the batch mlv cmd is :
[ERROR] Invalid block size at position 0xc9f0c400
i tried several version of mlv_dump with no Luck and found this post https://www.magiclantern.fm/forum/index.php?topic=19761.0
But it didn't help.

The file is from a non paid work with multiple camera so really no big deal if it's Lost but if there can be a fix such let me know what should i do to help.

On the shooting side everything went well with no bug but i recall i changed the iso on the Fly which sometime freeze the iso display during the record therefore i know i should never do that but bad habits :P. This was not the case here but i'm pretty sure i adjusted this iso setting while recording.

Also it's a very big file 15GB and first time i'm seeing this but i usually don't record that long.

Thanks in advance for the helpers.

Stop trolling around, etienne.

Hi walter,
just read that faq didn't saw mine :)

Ok Sorry if i did not make myself serious enough. Just want to assure you that my question was definitly not about the when?

but just asking (to whom have taken a look into it) is this a reasonable hope to have? or do there is evidence already that it could turn out to be something like the RT preview with a big question mark on if this is even doabble...

but rest assure i can definitly live without just as i can definitly live without even getting that answer.

Have fun & peace.

sorry, not yet. quite busy with having a life ;D

this is totally unaccaptable!!!  So just to get an idea is it something that just needs works to be done or is it something that needs  some massive issue to be fixed and is yet still uncertain?

Any news on bringing the MLV_SOUND to work with that branch?
#7
Hi all,

Is there a way to get 14bits losseless in one of the branches that support crop mode x3 & MLV sound in HD no need for higher resolution.

It seems that only the 4k Branch gets the lossless choices but this one as no MLV sound available... Am i wrong? Any other way?

Thanks, I did, but it still doesn't rec h264. So I assume this option doesn't support any crop_rec mode?

Exact it works only when realtime liveview is availaible it does work however with the crop mode enabled with the zoom (not the one inside ML)

Can someone give a clue how to make camera to rec h264 proxy on SD and not on CF card?

In ML Menu under the tool icon you will find "Card Settings" in that menu you will find Preferred Card choose SD Reboot and your done.

+1 for the sound also i currently have a work around which is really cumbersome but that works with Full HD defintion.

I activate proxy record
i choose the SD card in ML menu as the prefered card for writing.
In canon menu I set the IPB as codec (all-i gives me more crashes but this is probably due to a weak SD card). SD mode 640 does works aswell.
In the End you get 2 files : 1 proxy video with sound on SD and 1 Mute MLV on CF.

The problem with this techniques is that the 2 files does not start in SYNC (h264 always start first) so you need to resync you audio with the MLV and run an export of the audio to match the MLV sequence.
It's like a clap sync without the clap but as heavy to deal with though. The benefits i that you get a proxy file you can start working with and find a little hand to do the dirty work of exporting matching audio.

The problem is that it does not work with 3K Mode as there is no preview to make image match

So if getting sound into the MLV is still hard to manage maybe enabling any kind of poor preview to the 3k mode would help to do the trick in meanwhile. or even better a way to have the proxy start in sync with the MLV

Hey

Great job for the low bit depth it opens great perspective to play around the 3.5k.

Here is my bug encouters for low bit depth 8,9,10,11:

-  the expo is darken in the realtime preview and hdmi out. realtimre preview for 8 bit totally unusable (this is bas for focusing) framing mode is working better but focus is still not possible from there.

- 1:1 Tall have the lower of the image not displayed correctly like mentionned for slow mode

- non working on 3K mode and higher

Can we expect a mlv sound coming back? post synchro is so burden with just the beep :P

@a1ex

Hello thanx for taking the time to answering the question this is highly appreciated. i'm on the curve to go to URSA 4.6K but this new fonctions let me think my olds 5d3's have still some life to live.

regarding the fact that mlv mjpeg 8 bit compression
Quotewould simply compress Canon's YUV422 buffer (with their color science, picture styles, sharpness etc)

Are you absolutely sure regarding the sharpness. I'm asking because this is a fact that the clean hdmi as absolutely zero additionnal sharpness from the h264 files i have tested this thousands times. But the raw definitly resolves way more sharpness similar to what produces an A7sii, gh4 or gh5 in HD so i was sure that the 5d breaks something in between what you catch with rec_mod and what you get as h264 or hdmi out.

Now what i'm undestanding from your saying is that the compress Canon's YUV422 buffer is what is sent to the hdmi out right? If it's the case it's useless for sure but can it be something else. Can you think of any other way to compress to something like 15~25% even if it means we loose all the color depth from the raw but just keep that sharpness from it. I'm insisting on this because Personnally I would be so much be happy with an MLV without any color depth additional value but which would just have the real sharpness we can get from the current raw and that could allow like 60~90 minutes on a 128GB card.

Also I want to congrats on the slowmotion mods all options are awesome i just did a 1080 60P in 2:35 flawlessly. As mentionned the 1080 48P as a few corrupted frames and its preview is also a little off towards the down of the image compared to the canon preview but appart from that we could say this is 99% usable.

Finnally. The 3K Mode and UHD are absolutely awesome. I personnally don't see how we could use over 3360x1528 with spanning and sound in the future so any preview that would be x2 would just be the ultimate thing to make this usable.

I undestand that for now it's complete unknow hope someone will find a solution one day otherwise in regards of you're sayinf:
QuoteI can try to include the centered x5 zoom mode (which you can already use in the "classic" crop_rec builds), if that helps.
Sure It's definitly better than nothing to have access to canon x5 center preview again instead of pink frame eventhough it will not help with framing but it will help to pull focus correctly durin shooting.

Bravo again keep the good work. Looking very forward to integration to MLV2 with spanning and sound enabled...

Good Luck.

One question to the developpers do you know if the 3 things below would be possible one day:

1/ 1080x1080  (from 3x3 bining using the 3240x3240 sensor size). for a big anamorphic s65 lens.

2 / in the same way of the 14 bit losless mjpeg compression is an 8 bit mjpeg compression possible? so we can do low file size and get the real sharpness the 5d3 can offer (clean HDMI recorder on prores does not get any better sharpness than the in camera h264 file - whereas the raw files is always resolving much more sharpness)

3/ finally how far would you say you are from a working preview for the mode 3K, UHD, or zoom x5 and is it even possible?

Also you probably have thought this but the basic full sensor preview with blacktape on the sceen could make it and if the 1:1 sensor readout cannot show original preview then maybe a x3 preview instead of the x5. Would not be perfect but would definitly make it usable.

Thanx for the work it's a dream. Where is the TIP JAR already?

Bests.
