Thu, 21 Aug 2014 15:09:04 +0000 fatpig 11092@/talks/discussions I want to let you know of my new software, which I offer for free.

WAVI AutoMUX lets you choose directories which contain WAV and AVI files- and it will mux each wav into an avi with matching name.

I coded this some days ago to deal with the tedious muxing of mute AVIs which are created by Resolves processing of DNG sequences, which were recorded with a separate WAV file, like in most DNG recording cameras like Blackmagic, Sony FS700 or Magic Lantern. (at the moment just WAV/AVI, other formats might be added by request)

you can get it at: http://www.fatpigtures.com/wavi-automux.html you will need ffmpeg in its directory.

Let me know what you think.

Lets talk about big files http://personal-view.com/talks/discussion/9765/lets-talk-about-big-files Sun, 02 Mar 2014 03:46:17 +0000 UEstudios 9765@/talks/discussions So Im at this point where I directly transcode all my GH3 footage to prores4:4:4 (with Cinemartin) before performing my online editing. I edit offline out of crappy looking proxys because my system is crippled and slow. (Bulk rename utility allows me to keep all filenames consistent)

I edit my online on that Prores4:4:4 and then I export a DPX sequence out of AE. (Dpx's allow me to re-render specific parts of the piece without having to re-render all of it if something went wrong)

I want to put that back into Prores 4:4:4 but because Im on pc's I have very few options. Cinemartin doesnt cut it, it's giving too many problems to render Dpx sequences, specially adding the audio.

So I'm trying to find a way to get a 4:4:4 final output from my DPX sequence. The only workaround I found is (and I don't know if im totally messing up everything doing this) .. rendering it in "avi uncompressed" then import to cinemartin and then transcode to prores4:4:4 for archive or whatever.

Now: This Avi uncompressed format is everywhere from Vegas to premiere ae etc, what is it exacly? is it any better than prores444? Some people told me it has been "discontinued" or "just dont use that shit" type of things...

Is it a 4:4:4 format? Am I mixing different concepts here? Anybody using that?

Sure, filesize are enourmous, but im on working on 2 rigs, one for transcoding with 6tb space and another one for editing (a gaming laptop) with a 512gb ssd on it, both plugged to each other with a 1gbps lan. So... I can actually handle those filesizes.

To my eye, results look good, the final result is that it actually breaks down less when performing online that if I would just edit over the original h264.mov from the gh3

Any insights? Anybody can explain me in detail what is that uncompressed avi about?

Edit: So no, I'm not so sure that is better to transcode... just ran a test:

Took 1 50p50mbpsIPB clip from the GH3 Transcode to Prores444 and Avi uncompressed apply same codec destruction pack of effects check

I noted one thing: Artifacts would pop out like crazy when doing the same on a darker scene, although on that one of the test where there is a nice dynamic range... I actually had some trouble making the artifacts pop out properly.
