Background (computer Nvidea 3060 ti, AMD Ryzen Threadripper PRO 3975WX 32-Cores 3.50 GHz, 64gb Ram, 12gb vram)

vMix has many amazing features. Among them, the Zoom direct ability. I have set my production to record each individual Zoom input to its own track for easier editing. However, when recording using vMix AVI (one of the supported all audio bus recording formats), I need to convert the footage to .mov just to get the recording imported to Adobe Premiere. After a long import time, I can see the footage, but audio is choppy and will drop out even though I can see the waveforms. It is unusable for any editing purposes. AVI is also equally as unusable.

The alternative, record as an mp4 with a separate wav file, which breaks itself up even without checking the "separate every however many minutes" box. It's not pro res, and I get multiple audio files after the fact. It works, but not preferable either.

We need an editable pro res format that has all audio busses included.

If I'm missing something I'm happy to be taught.

Thank you!

The conversion from vMix AVI shouldn't be changing your timecode to a meaningful extent.

I record in vMix AVI with the WAV file record option enabled.

Then I use the vMix Media Converter to convert the vMix AVI file.

Then I immediately use Handbrake to shrink the converted file and strip the audio from it (to shrink it further).

In editing, I timecode align the Handbrake file and the WAV audio file, and if it's off, it's not off by any amount I notice.

But my recordings are rarely longer than 30-45 minutes, so if you're going for hours, any drift might be more obvious.

From the help:
Editing recordings on other computers
vMix AVI files recorded using the vMix Video Codec can be edited on any Windows PC in most video editors including Adobe Premiere and Magix Vegas Pro.
Simply install a copy of vMix on any system used for editing. vMix does not need a license on these computers and does not need to be activated, but does need to be installed.

Converting vMix AVI files to ProRes MOV
vMix includes a program called vMix Media Converter that can transcode multiple vMix AVI files to ProRes MOV files.
This program can be located in the Windows Start Menu.

Hope that helps.

Hey all, a few things:

- Timecode isn't my issue, that is all fine.
- I've used the vMix AVI converter tool, but even then the footage loads tremendously slow into Premiere.

Try recording content as Vmix AVI with all audio busses enabled in the recording. If it's more than a few minutes long, you won't be able to load it in to Premiere (assuming you have audio on multiple tracks). If you use the conversion tool, it works-ish, but editing is real bad and it still takes a very long time to load into Premiere.

I don't want to use handbrake to covert this footage because I cannot maintain the audio track separation (16 tracks), it always mixes down to less, which defeats the purpose of recording this way.

What I need is a .mov or other prores format that can record all audio busses and be able to load into Premiere in a timely fashion and edit reliably. Preferably, .mov in a QuicktimeSpeedHQ format. That is what has been working the best for me on my Tricaster TC1 for years.

Well, yeah. They're gigantic ProRes files. That's exactly why I use Handbrake to shrink them before working with them.

As I said, I completely remove the audio when I use Handbrake. The resulting files have no audio tracks. None.

Every recording format in vMix offers the ability to record the selected bus(es) to a WAV file.

You don't need audio on the video files when you have audio in an audio file that accurately timecode aligns with the video file in a NLE.

As I said, that's exactly what I do.

Your post explicitly said that you were open to being told what you were missing. I replied by giving you a workflow that I use to achieve the exact same thing you're looking to achieve.

You can either take it or wait to see if vMix eventually implements your suggestion.

I will tell you that the features I see implemented that I recognize from suggestions on this forum generally take about 3-5 years from the first mention on this forum to implementation.

So I'd suggest taking my advice on an alternative workflow, but that's up to you.

The files I get from my Triccaster are very large, often over 100gb, but they load in under 5 min, so having a 30-40gb file from vMix should be no problem, but unfortunately it is. I'm currently using the mp4 video recording with separate WAV file method, which works ok, but it still breaks up the WAV files every 46 minutes or so even though I don't have that option checked, which is annoying because I have to contend which a static noise when it transitions (which I can take away in Premiere but it sucks that I have to do it). I have 6 broadcasts in October that go from 8am-5pm straight, so that's going to be a lot of files at the end of the day as opposed to the few I used to get with the Tricaster.

So essentially, there is no other solution yet than the one I'm using based on your experiences. Womp.

Again, every option, including vMix AVI, offers the ability to get a WAV file record.

If you have no issues with the picture quality of the vMix AVI files, there's no reason to keep using MP4, when you have an issue with how it processes longer files.

The vMix AVI files I get for a ~30 minute recording are over 100GB.

The ProRes files are 2-3x that.

I am not remotely surprised that they're sluggish.

Which is why I substantially compress them to make them not sluggish.

The audio that's attached to them is irrelevant because I have a WAV audio file. So what Handbrake does or doesn't do to the audio does not matter. Telling Handbrake to remove the audio all together just makes the file sizes even smaller without losing anything you actually need.

As I said, with longer files, you may notice sync drift after running through the vMix Media Converter and Handbrake. I do not know if you will or not.

But I'm not sure why you're acting like I'm telling you the only option is to keep using MP4 recordings.

I also see problems to load long vmix avi files into premiere. Im using mp4 and then do what you say. You can also try to merge the wav files with an external program and then put them into premiere. Also I have done in some posts the same. To compare tricaster vs vmix.And wonder why in pc terms an old outdated hw can do too many things that vmix cannot do.
But Your PC with threadripper with vmix pro license costs about the 1/3 of TC1 https://www.bhphotovideo..._r001_tricaster_tc1.html and as overall PC machine makes a lot better than tricaster and be a software video mixer when others machine like tricaster are hw mixers based on PC hw. So un-fortunatelly no sw or hw machine is perfect
As for feature requests I believe that vmix team read and know all of them, we have asked all these years in the forum. The easy way to do them is the "OBS" 3rd party plugin and the user must know that even his PC is not faulty,the feature may or may not work today and tomorrow will work..
