For the new MLV (raw v2) and MLV+sound is anyone able to record 720 continuously?

I know raw v1 records 720 perfectly, but i've been hoping to adding basic sound.  i have a uhs1 card and cant seem to go past 40-60 seconds before a skipped frame.  It shows its going at ~36mbs (my card maxes at 45mbs write speed) and still skips.  I'm pretty sure its the limited speed of the 650D's controller, but that means 720 isn't going to be attainable w/ MLV.

I know this is not helpful at all for answering the question, but I suppose it would be beneficial to point out that a digital zoom is literally just a normal ol' image cropped and scaled up... which is functionally identical to just about every picture editor or ms paint equivalent out there.

pixels are pixels, sadly you cant record an image in higher (or even equivalent) definition using a digital zoom.  In fact, the on-camera version of digital zoom would likely be lower quality than using photoshop for an array of reasons regarding compute power/algorithms.

Sorry, i couldn't directly answer, but at least this is an alternative.

A drag and drop feature might be a nice addition to speed up the workflow.  Great work, very useful!

Because it is considered a temp patch, its just best to wait till the audio chip is programed so full control of audio will be available then merge that. This patch is just a way to turn meters on so we can use them.

Ahh, that makes sense.  I swear, everyone who has contributed to ML is awesome! You all have done some really impressive work :)  It's hard to imagine that the first build was only a few months ago.

Until our audio chip gets programmed yoo probably wont see audio meters in the nightly build any time soon, this is why I try to keep my version updated for anyone that wants a build with them.

If you got it working, how come they haven't merged it?

The MAC version of PDR continues to work with the latest nightlies? The windows version used to work but stopped after a certain version of ML (for reasons unbeknownst to me) so I switched to raw2dng...

Indeed it does, its been pretty consistent.  I was suprized to also see that it also admirably handles the resolution below 720 as well (cant remember exactly what resolution that is off hand).  If I recall, anything that wasn't 720 was all sorts of no good.  However, that doesn't seem to be the case in my limited test.  I haven't looked too closely at IQ pre/post PDR, but it certianly cleared up the pink dots at a casual glance!

I dont think google will display them accurately, but you can download and then compare.

Thank you! Seems you are right, it IS raw2dng. I wasn't aware that adobe was running a dot-remover - makes a lot more sense now.

I guess it's time for me to finally learn C++ and dive in to trying to fix raw2dng. I like the workflow I have with raw2dng and Resolve and I really shouldn't be using the copy of AE that I found on the side of the road (nor do I want to buy it)

Glad I could help!  If you have a mac nearby, the best tool i've found so far is PDR interp by rewind.  It's written in java so i'd assume it would run on a PC as well?  It's very robust and produces superior results (imo).  It certianly can be difficult to find though, as its buried in a PDR topic somewhere on the forum.  I can re-up it if its beneficial, or someone can reply to this with a forum link if they find it.

Sidenote, if you're affiliated (even remotely) with an educational institution, you can get Adobe CC for $19/mo if cost is an issue with adobe's suite of stuff.  I'm not particularly a fan of leasing software... but its an option.

Dave,  I was able to replicate the issue after poking through frame by frame.  After some testing and mucking around, i'm leaning toward a cs2x2 issue.  AE doesn't show the dots because whenever you're working with DNGs it will automaticially run dot remover behind the scenes, thus a clean image.  Actually, all adobe tools do this when working with raw/dng.  I baked in the black dots using Davinci to export into a prores sequence and took that into AE and that made them visable.

My best suggestion would be to take the source footage and without using cs2x2, or any PDR for that matter, check the frames.  Sure it'll have pink dots but it will identify the issue: either Davinci's raw engine is wonky (not that likely) or its cs2x2 (more likely).

Just a quick note to all those following ML development.  Feb17th is a solid build to try if you've been hesitant to switch from the august alpha.  Things are far more polished now, though there are still cosmetic glitches.

MLV rec/snd is still unusable.  I get about 4-8 sec before skipping @ 720p where i can get continuous on rec_raw at the same settings.  The testmode shows a massive drop in data throughput (22-28 depending on the B/M combination).  Currently there are no tools available for macs to extract dng/audio from the MLV file either that are particularly robust...

EDIT: Should be noted that if you drop down a resolution level to 1152x648 you can get continuous.

Interesting bug: somehow the crop overlay for raw video was translucent, snazzy... couldn't tell if this was the intention though since it only showed up once then after a reset went back to solid black.

Can I ask the help of someone who has Resolve 10 lite on their system? I need someone to load my project on their setup to see if they are getting the same artifacts that I am.

This was recorded with the latest ML nightly on my 650d, converted to DNGs using raw2dng cs2x2, and I'm getting dark pixellation in the overexposed areas that DOES NOT seem to appear in AE or Windows Photo Viewer.

Here's the .DNG stills (50MB):

Here's the .DRP (project settings) file:


Hey Dave,
I tried it on my mac using davinci 10.1, didnt' see any noticable difference between DR and AE or even lightroom (for raw/dng viewing).  Can you post a screenshot?
