masc, thanks again for your in-depth answers and explanations, really helps a lot.

Since I don't use audio at all on MLV files, I think I'll just Apple's AVFoundation, thanks for the precision.

Looking forward to the new white balance algorithm we've been hearing so much about.

In the meantime I'll enjoy this amazing application.

Thanks for all your good work.

masc thanks so much for your quick reply.

that's good to know that fps is outputting better than expected, because i came from a trial with MLRawViewer, where it played back every frame in real time without using much cpu, maybe it was using some form of low res cached proxy? but it's good to know it's normal behavior on MLV App.

for the exporting, I cut mostly on FCPX as well, you picked AMaZE because it renders closer to the original RAW video than Bilinear?
I just exported the same video using ffmpeg Kostya and Apple AVFoundation, but cannot seem to tell the difference. Do you use the standard ffmpeg Kostya?

For the white balance temperature example, here are a couple of screenshots showing cool (2000K) neutral (5500K) and warm (10000K) as you can see the difference between neutral and warm is negligible, but when I modify white balance in for example MLRawViewer there is a pronounced difference between neutral and warm.

Thanks again for your help,

Nick

Hello,

New to ML in general, and just jumped ship from MLRawViewer thread, where unfortunately exporting in ProRes is not compatible with High Sierra. I was recommended to try MLV App, and so far it is great. I did go through a lot of the threads on this forum and some of the posts on this thread.

I have a couple of issues if anyone could of any help. I'm sorry in advance if the questions have been previously answered as I did keyword searches and didn't find much.

1. For white balance, I know there's a bump on including a picker for the future. But for the 'Temperature' it seems that the cooler I move the slider towards 2000K, the image does respond and get properly cool/blue. But as I move the slider towards the warm end of the spectrum there seems to be very little if any change to the image, is this a know issue?

2. During Playback of the MLV in the preview window, I usually get 17-20 fps on a 24 fps file. Is this normal? I tried changing the Debayer for Preview Setting from Bilinear to Amaze to Amaze Cached. The Amaze and Amaze Cached both played back files at half the Bilinear (10-12 fps), even when I left the Amaze Cache, cache the video it made no difference.

3. For exporting, what is the most used/popular setting for ffmpeg and Debayer?

I shoot on a 5DM2 1856*1044 @ 23.976 fps 14-bit uncompressed. Running MLV app on a 2013 MBPr.

Thanks for all your help,

Thanks for your useful information guys. I gave MLV app a go, seems pretty robust for now, and I think as you said, there's been slow development on the MLRawViewer, so it might be better future-proofing getting to work with MLV app as things stand.

Check out Switch, too, it has some pretty robust features that could make your life easier working with prores.

As for Switch, the only thing I found relating to it is a command line tool, do you use that version or is there a GUI version available somewhere?

Thanks

Hi Kharak,

Thanks for your quick reply.

Sorry for not mentioning my export format, it was indeed ProRes that I'm trying to export to, and it's not working.

DNG works fine. But I have always worked in ProRes, so when I saw MlRawViewer could export to ProRes I was so happy.

I'll check out MLV app as you mentioned. From your experience if there was an export from both MLRawViewer and MLVApp both in ProRes on the same file, should the final result be theoretically the same?

I can downgrade to a previous version of macOS (the current one is terrible anyways) if MLRawViewer is worth it.

Thanks again for your help,

Nick

Not sure if I'm in the right thread, but it seems like all MLRawViewer stuff are here.

I am on a 2013 MacBook Pro Retina with the latest version of High Sierra 10.13.3 and downloaded MLRawViewer 1.4.3.
I have MLV files from a Canon 5D Mark II at 1856x1044 @ 23.976 fps.

I am trying to export the file with MLRawViewer but nothing is happening.

To export we press E twice right? Once to add to Queue and another time to export?

Also how do we select a location target folder where we want to export?

Any help would be appreciated, and sorry if I posted in the wrong thread, I can see it's very strict, I did my best to pick the right one.

Thanks,

Nick

Hello,

New to ML, read the whole User Guide, and went in depth the forums to see if there was a way to completely disable recording any Audio while recording a movie.

5DMKII, latest firmware/build.

Any help appreciated,
