Video editors...Save tons of hard drive space with this tip

Thanks to smashvidz I have come up with an idea.
They already had the idea, but I thought I would share it and see what you think.

Here are my thoughts.

----------------------------------------------------------------------

Those who edit videos and like to have clean and dirty why not do this.

In your editing program when everything is all lined up and ready and you have the video file, clean and dirty audio lined up perfectly.

create two audio files from that (mp3) one clean and one dirty with no video.

Then create an mp4 with no audio (like lidz) and then you will have one video file and two audio files.

Load them all into ssl.
Load the clean audio into the deck and set video with the audioless mp4 you created. You know the audio is in sync because you just lined them up in vegas/premiere/Final cut.

Load the dirty audio and do the same.
no you just saved yourself an average of 100Mb per video.

100 videos time 100Mb = 10 Gigs on avg saved if you like clean and dirty.

I'm not sure how it will affect performance since you are reading audio and video file from the hdd at the same time, but ram should be able to handle that.

I like the concept, but i honestly dont think it will work as perfectly as everyone thinks...

I might try it today. I'm going to load up an old edit and add the dirty audio and see how it goes.

And what happens when it starts to float and you cant control one or the other...your going to look like a retard trainwrecking audio/video. The only thing I can think of is if you create cue points on both the audio and video where if it does start drifting you can catch the video up at a certain point in the audio track (cuepoint).

I don't know if the audio/video would drift.

I haven't tested it, but if it did drift there would be no way to fix it.

I think the audio and video are in sync by time only. So, if the audio is at 1:04 the video will sync at 1:04 as well.

a friend of mine did edits like this before I discovered demux/remuxing, as a way to make acapellas and intro edits without having to wait for a render

Never got to see it in action, but he said it worked perfectly linking an acapella audio file to the original video file. The difference is he didn't create a video file without audio, just linked the original video version to the new mp3 audio track

for the price of hard drive space I'd rather just demux/remux, and be sure the video is synced properly, but that's just me

No drifting homie! We've been testing for a long time. Heres one example:

1 - Video stream
12 - Audio Streams
single - clean
single - dirty
xtendz - clean
xtendz - dirty
snipz - clean
snipz - dirty
acapella - clean
acapella - dirty
blenx-in - clean
blenx-in - dirty
blenx - clean
blenx - dirty

thats a example of what would be in a zip file. cues will already be placed ahead for tracks like acapella & singles. So if you have your serato setup as "start at first cue" your good. Relative mode baby!

You don't have to understand how it works to use it. All you have to do is organize the audio like you normally do & place the video (LiD) in a specified directory (root/LIDZ)

Now when you load any of the audio streams, the video will already be attached. All the work will already have been done for you.

The only down fall is the Snipz version, the outro will have the second verse (video) since its one video stream. Solution is either a. get the snipz video version, or b. make it so you do not see the video outro when mixing in the new one :-)

Marx,

how does this affect performance. The old style has audio and video in one file, now the hard drive will read 2 files at once. audio and video. Does it affect anything or is it all pretty much stored in ram to not affect the hdd read/write.

We're not changing anything. This is a addition. We've had no problems with our testing. I'll see if we can post a demo over the weekend.

I got the akon, but no audio, only links.

I'll hit you up offline about it.

Dayum. The forums are now the new Craigslist Casual Encounters. LOL

Ya that's correct puma. Lidz are just a video stream. So the section lidz is nothing but video streams. Your confusing it with stemz, which has a lidz in the package. Stemz will have the video and all the audios in a zip. When stemz is released, it will have a button just like the normal releases do :-)

Taken from [all-streaming-media.com]

"MP4 supports all kinds of multimedia content (multiple audio streams, video streams, subtitle streams, pictures) and advanced content (called "Rich Media" or "BIFS") like 2D and 3D graphics, user interactivity, DVD-like menus. MP4 is a streamable format."

This prolly been asked before but.. would there be any way to just add it all to one mp4 and then choose like you do on a dvd player which version you would like to play? Is this restricted in vsl?

Yes, I've been saying this for a LONG time. Serato, we *need* this feature. Being able to have a single MP4 with multiple audio streams is the best solution.

Indeed.. i just created a simple mp4 with menus at work using mp4menugui.. i think this would help us out alot in the long run. Wouldnt we just need to have access to be able to click inside one of the preview windows to select which version we would like to play in vsl? doing futher research on this..

Yes that is ideal!

But serato doesn't seem to be interested in adding this feature. So we're taking into another direction. Once they implement this then we would of course add the feature as well. But mp4 does support multiple audio streams.

im suprised mp4box did it like in 10 seconds man.. wow

Yea man. But useless if serato doesn't make it readable.

indeed..

wow...i didn't even know mp4's could have multiple audio streams...

but the above tip does seem feasible..

Best thread ever. Thanks for the knowledge Marx & Puma. I tried this a couple of times before but I think I didn't render my audio files at the same time/from the same source so it didn't work very well but going to give it a shot again. I knew about multiple streams...come Serato, add the feature to VSL!

the problem i see with this its when you LOOP the audio, since the video cant be loop.
People like me who uses looping alot wont be able to work with LIDZ =(

actually your incorrect Muerte.

The Lidz is just a video stream & basically is just a dummy file. All cues, loops, overviews, tags, video associations etc are stored in the m4a file.

You will have to prep each m4a file, but you have to do this now anyway with multiple files. So if you use loop a lot, it will NOT be a problem :-)

I too would like multiple audio stream support with Serato :-)

Marx i see the lidz uses 9inch (no homo) but there is no audio. what if I don't have the 9inch remix of a certain track.

then u have to buy it.

Lidz will be associated with other services too. Lidz is good for djs that use other services as most play the audio first :-)

when the video comes out BAM just add the LID to your audio. I dunno about you but I hate resetting cues & loops.

pure genius :-)

Stemz is the one like I described that you can use for clean and dirty audio?

Well it actually works for both if theres multiple versions.

Stemz will have the all audio files all ready for you in a zip file. Clean, Dirty, Xtendz Snipz, Blenx, Acapella ETc. One LID

Nice.

I still am going to try this on my next edit. and test it out.
