Hi Pesi

which version of Premiere?
what are your settings for recording?
Was it MultiCorder or just Record?

Never faced such an issue with my recordings!

I don't have this problem, but I still use Premiere 6.5

AFAIK it's not possible to use strict CBR for MP4 recordings in vMix. However it's possible to use others codecs like ProRes or DNxHD (VC3) which will produce larger files but absolutely usable with Premiere. Other option is MPEG2 TS where CBR is default option. Or use external out to feed FFMPEG with your own recording profiles.

Make some tests and find what's best for you

I did read that and I know that recording as AVI or Mpeg2 may solve the issue.
However, clients usually want the recorded version right away as-is, for their own use to play on their computers at their office and MP4 is the most convenient format to provide them with right after the event on their own USB flash drive.

Now if they suddenly decide on an edited version (which is a rare request) that MP4 will not work in Premiere CC 2015 (which is what I have).
If I knew beforehand that the client will want me to edit I could record in another format, but that is not usually the case.

Am quite pi__ed off at Adobe for not solving this issue which has been ongoing for over a year!

@ pesi

Typically, I would say no.
MPEG-2 is usually used as a DVD format, not an on-line streaming format.
In fact, AFAIK, YouTube will not even allow you to upload such files (i.e. to prevent dvd's from being uploaded).
How are they embedding or hosting the video on their website?
Often, video sharing or hosting sites re-encode the video anyway for playback on multiple devices and/or multiple bit-rates, they will often accept many different formats and convert to MP4.

Hi Pesi

you can use external out to feed another recorder at the same time you're recording in vMix.

Hi DWAM - I did try the external recorder on the same computer but gave up because I did not want to complicate the issue and have anything interfere with the original recording or webcast by running an additional piece of software on the same system (call me chicken!)

Speegs - you've just given me an idea about getting one more toy for Christmas and how to justify it to my boss (the wife)! So Thanks! I will take a good look at all those options you laid out.

The Atomos and Black Magic Video Assist Range have no problems importing the files to Premier in either ProRes or AVID. The size of the files might be an issue, because they are "Pro" quality these devices generally record at 50mbit/s + up to 220mbit/s depending on what format you select. They are very much about professional broadcast quality standards, getting all the colour information possible. So don't give you the option to pick your own bitrate, but you can pick one of many preset formats.

ProRes is what FinalCut likes, Premier doesn't much care about ProRes or Avid. There is heaps of details on ProRes vs Avid like this: https://forums.adobe.com/thread/1098146 I think for me both are very good quality beyond my expectations so I find myself using the lower file sizes. The exception is ProRes Proxy, I find that quality is too low, but it's called Proxy for a reason it's not designed for final output recordings.

Whereas the EzRecorder 130 box tops out at around 30mbit, you can pick your own bitrate up to the limit. Seems they have a new 310 model on their website not sure what it's limit is.

Those having problems on the forum with ProRes files seem to be having problems with the ones recorded by Vmix, not by these professional recording devices from Atomos or Black Magic from my understanding. These hardware devices are very STRICT on standards, frame rates, resolutions, colour, timecodes, XML metadata files. Hope that helps.

I've been using Premier CC 2015, 2016 and 2017 (I upgrade all the time). So far not one file from a Atomos Ninja or Black Magic Video Assist 4K has been rejected by Premier. I record to SSD (Ninja Blade) or 1000x SDHC memory card (Video Assist 4K).

Supported Programs for a Ninja Blade (I'd go as far to so "thoroughly tested"), beware of older version maybe:

FCPX/FCP7+
Media Composer 5.0+
Premiere 5.5+
EDIUS 6.0+
Vegas Pro 10+
Lightworks
Autodesk Smoke 2015

Using both the Ninja Blade and the Video Assist 4K. (Maybe not a fair comparison as Video Assist 4K is newer and more expensive).

I like the capacity on a Ninja Blade (2TB SSD no problem). I hate that the batteries do not recharge inside the unit. It's also bulky and awkward. It's tough! Battery life is good.

I like the screen on the VA4K, it's awesome. It's interface is simple. Love that it can record to one SDHC and you can switch to the other one. It also has SDI and HDMI in the same unit, will help you out as a converter in a pinch. Battery life is pretty terrible as you see in many reviews. The high speed SDHC cards are expensive per GB and I've been unable to find them with capacities higher than 256GB each. Nice and small, so handy to keep recording and take one back to edit. I can't do that on the Ninja as it only has one storage device. Definately check the firmware is the latest on the VA4K. New features came in more recent firmware, especially more recording types. While strong and well built, the Ninja Blade feels stronger!

Luckily when not using them as "testing" devices I have them plugged in, I record for 8 hours nothing really lasts that long on battery.

I have not tried the other Atomos devices. They have newer models that might well be better than the Video Assist 4K.

So yes, there is an AC power supply available for atomos devices which takes care of one concern.
Now the only other will be file sizes - I read on an Adobe forum that at the highest res, it swallows up about 100 GB per hour of video!
That would mean a lot of cards for an 8 hour event!

I am looking at getting an Hdmi-in-out device to record to my second laptop - the Blackmagic Mini recorder would have been ideal but its out is Thunderbolt, which my laptop does not have a port for. :-(

Yes they all have an AC Power option, the batteries on the Ninja do not charge inside the unit. It's an external wall charger.

At full quality I can't get enough storage. So I usually don't record at the full quality setting. I go for a 45mbit setting which is sufficient. Many Pros say that is no high enough, but I'm not recording the super bowl.

Top quality video uses really high data rates. There are quite a few settings available on both devices.

I only have 2 x 256GB SDHC cards at the moment. I copy the files to my editing computer and rotate the empty one back in. At the quality I use 512GB does get me through a full day with quite a bit of room to spare.

I used a second computer in the past, guess I just wanted to get some options where a computer was not involved in the capture.

The Ninja Star looks like a good device, I don't use one. I wanted a screen to see what is recording. Long days of the same stuff it's easy to forget to hit record. These devices make it very obvious you are recording :)

The sound guy hits record on the recording monitor (also watches the levels coming out of Vmix). Vmix operator also hits record. I always try to record 2 copies. Lowest Quality is in Vmix. In what I do the video is used to resolve disputes, so having 2 copies is a must. Technically I also have the live stream recorded on Youtube as well, but you can't roll the footage back all the way until Youtube finishes processing.

That might be the actual easiest recording ever, stream to Youtube live it lets you roll back 2-4 hours just by moving the slider. Of course NO INTERNET = NO RECORDING! Hence why I always double record in addition. Yes I have missed hitting record on one and had an Internet issue and the last recording was utilized. Fail-safes are my friend!

Can you have too many backups? I think not really (but you do run out storage). You are never going to capture that live thing ever again, in what I do it's the sale of a horse potentially of a value up to $3M. Telling the owner you didn't capture the sale of their prized horse due to a malfunction isn't a good conversation, or the TV station who wants to show the video of it selling because it just won an important race 3-5 years later. At the time I would have no idea if the horse was a champion to be or not. The next horse being filmed could be Phar Lap and become some kind of legend, or one that never makes it to a racetrack.

On top of all that, Vmix sometimes has to be unattended, which further complicates matters. This is because the operator is also an IT expert fixing everything else. At least the sound guy doesn't run off to fix a printer in the middle of a production. More reason to have the sound guy monitor a recording :) Workflows take time, they can always be improved. All the time I'm working to improve. My workflow is vastly different to most in the forum I'm sure.
