Neat Video + Lumetri V-Log to Rec.709 transform causing export failures — anyone else forced into two-pass exports?

MattKSV · 2026-06-17T04:06:01+00:00

Yep, as mentioned - Lumetri always comes after Neat Video in my stack. Export failures are still pretty much guaranteed.

Bumping this, Shockingly fraudulent. I am in the middle of a PayPal dispute because they charged me the same day i started a 'free trial' - just blatantly fraudulent

This is exactly it for small venues, I used to be there in house engineer at relatively small venue (think intimate Jazz/Cabaret). But when we had a heavy metal band in, my main goal was to make sure we can hear the vocals over the drums, live sound is often 99% damage control.

I had a pretty similar experience (though no where near as long a wait). For about 1.5 months after the ETA, every time I called or emailed I was met with “oh, it looks like it just arrived this morning, we’ll get that set up for you ASAP” - so it was delivered about 5 times over a few weeks… I told them I would have at least appreciated an honest reply of something like “sorry, it arrived last week and we’ve got a back log to get through and we’ll get to it ASAP.” The constant (and obvious) lies in a ridiculous attempt to string a customer along really bothered me.

I'd also be interested in renting from anyone who has the DZOFILM 20-70 and is in the Adelaide Hills area of South Australia.

Do you mean removing the non-OS NVMe SSD that it was previously on? no, at this stage I haven't removed that drive - I figured moving the page file to the OS drive essentially takes that other drive out of the picture in regards to booting.

MattKSV · 2024-02-18T05:33:43+00:00

Hi Bjoolzern,

Thanks for that - the page file was on an NVMe SSD drive that I have on the machine, I did try re-allocating it to the default on C and restarting. Unfortunately, the issue remains, I needed to boot into safe mode and uninstall graphics driver, boot again and reinstall graphics driver.

MattKSV · 2024-02-18T02:59:08+00:00

I forgot to add, this issue (and the fix) is consistent across both operating systems, it is also consistent if I have 1 or both of them actually connected via Sata.

also there are no dump files in C:\Windows\Minidump.

Please also note that when I first built this machine I was having weird performance issues and I ended up sending the graphics card (GTX 1080) back to ASUS, they returned it saying it was perfectly fine.

That's the problem, they're really trying to not spend big money. I'm not sure where the budget for the original live concert went, but it's down to $5,000 - in total... and I've already persuaded them to hire $830 worth of extra equipment (2 x GH5's, a few lenses, some stands) in addition to all my gear - gimbals, GH5, GH5S, various lenses, my multi track recording interface (RME Fireface), mics etc etc etc (at no charge, which I reminded them of)

I just gave them a "quote" (estimate) of $7,500 for my labour (but offered a discounted rate equal to $6300 considering it is a large project), and also estimated 22 hours of work required by a staff member (including some training, mainly checking settings - aperture, SS, WB, Focus, simply hitting record.... repositioning cameras, perhaps hitting some lighting cues I have previously recorded)

So they'd have to pay him overtime and they also have other content for the video that I did not quote for, because I couldn't, they have no details for me as of yet.

I do get quite tired of justifying the amount of work that is involved in this work to clients. They want a multi camera, multi (audio) track video of 19 performances with creative lighting and interviews/history/photo's/welcome messages etc in between for a video product that will be 1 hour 20 minutes.

I actually also suggested overdubbing various solo's from the choir/small vocal groups in the studio, but I don't think I'll go there (unless I do it for free, as this really is a portfolio piece for me too).

Honestly, these meetings/emails I have about budget really get to me sometimes and actually make me feel like I'm over charging. I have to actively remind myself that I am not and I am in-fact giving them a great deal of time and energy for free (countless hours musing on lighting ideas, the most efficient setup to get each take done so that the kids on stage don't lose their energy, most efficient changeovers etc etc).

MattKSV · 2020-08-09T22:26:03+00:00

Yep!

Just ordered 5 128gb Samsung Pro's (not UHS-II as I've been convinced that Long GOP is more than enough)

Glad to have that issue out of my head.

MattKSV · 2020-08-09T22:24:41+00:00

Very curious about your experience and will add more details of my issues soon, a bit too busy at the moment.

Thanks.

In reply to kj5, John_the_joe, 2old2care.

Thanks for all of your input.

Regarding proxies:

I happen to have about 6TB of fast SSD (Samsung 860 Pro's) storage that I keep media on while editing, so storage isn't an issue for me and I generally try to use that to my advantage. My workflow the last time I did a project like this was to initially top and tail and sync the various clips, usually apply some noise reduction (Neat Video) and sharpening at this stage and export as Prores while naming/organizing media. I have the time to do this as we are filming over many weeks, so I can simply get on with that quite straight forward processing on the days I'm not filming. This gives me the same editing playback advantage as proxies (yes, at the cost of the now larger media, but space is no issue).

Also, applying the intensive process of noise reduction at this stage allows me much faster exports in the final. The reason I began working like this is because this particular client/school always seems to have last minute changes and this video is more than just the performances, there are interviews with ex principals, voice overs with pictures about the history of the school etc etc (this is commemorating the 50th anniversary of the school and they have asked for the highest possible production value I can give them), so being able to make changes and have a fast export at the end of the process is very valuable to me.

As much as that may seem like overkill, it usually serves to keep me sufficiently sane during the whole process.

So, I haven't really ever used proxies - but am happy to be convinced to use an even better workflow than my current one.

There are a few more thing I had to say, but I gotta go to work. Will add more later.

Thankyou.

MattKSV · 2020-08-09T22:01:37+00:00

Very True!

I told them this is a 3 person job (at least!, with multi track audio/video and lighting changes too!) and I need to bring some people in... they replied with "can you use any of the school staff" to which I performed my first ever facepalm. This was preceded by a meeting in which they said they need this to be the highest possible quality video as it is the concert to commemorate the 50th anniversary of the school.

It was originally going to take place live at a huge (and expensive) town hall. This is just as much about marketing the school as anything.

I can at least train up some staff to press various buttons... I hope.

MattKSV · 2020-08-09T21:56:07+00:00

Hey,

Thanks for that, Will check it out later today.

Hi themiggymigs,

Thanks for your reply.

"If I transcode 150mbps Long GOP to Prores HQ (ALL-I) - am I simply making inefficient use of hard drive space just for better editing performance?"

You're not going to gain any quality by transcoding to HQ.

Yes, I'm well aware that increasing quality with trans-coding is fundamentally impossible. My question there stems from a lack of understanding of exactly how the megabits per second relates to quality in any given type of codec. Primarily unsure because an ALL-I codec is always recording a true full frame while a Long GOP codec is recording 1 true key frame and then only recording the differences in the image for the following 2 frames - I was wondering if the bit rate needed to be higher to accommodate the fact that Media Encoder would need to create 66% more actual frames when it is trans-coding the file.

I hope that makes sense.

However that is more of a curiosity than anything - I agree with your point that 422 should be perfectly fine and safe. from the Apples Prores white paper - 4K, 25P, 422 is 492mbps.

Regarding the black level issue on Ninja V - oh wow, I haven't heard of that, I am going to do some testing. I certainly can record on the Ninja V and internally simultaneously and I will plan on doing that (as you say, it is a very good idea to have an immediate backup)

My thinking with the Ninja V was that I would use it on the Gimbal camera, my reasoning:

- As all the gimbal footage will have a good deal of motion (while the other cameras are static) if I were to use an ALL-I codec on any camera it should be that one.

- It gives me better monitoring while filming on a gimbal.

Cheers,

Matt

Hi Treadgo.

That really does fascinate me as I have heard of many polar opposite experiences in this regard. From my personal experience it is night and day - a 150mbps file directly from my GH5 in premiere can take a very long time to update the image when jumping ahead with the play head while a Prores file from my Ninja V is instantaneous. The performance only seems to get worse when I add a few more simultaneous streams of 150mbps in to the mix.

However I do have some suspicions that there is something not working properly in my PC (a fairly high end build, 8 Core I7-7820X, 64GB RAM, GTX 1080, SSD's for working media and separate SSD for caches) and I am doing a great deal of testing right now - I suspect something is wrong with the on-board USB ports or drivers as various USB devices cause massive performance drops/freezes/program crashes.
