Why "Bounce" takes so long?
on Jul 10, 2007 at 2:13:23 pm

I have a background in video, but am new to audio recording. I work for a medical company who is turning certain titles into audio products. (Who can resist the urge to study medical terminology with an ipod at the beach after all?)

I'm out of my element here and wondering why it takes so long to "bounce" the files in the studio. I have no way of verifying this time, obviously. How come I can render video + audio so quickly, but professional audio is taking HOURS and HOURS to churn wav files? We are paying a special rate for this time- half of standard recording/editing time, yet I am stumped by it.

Is there a typical bounce ratio to finished minutes? Why does it take so long?

Thanks!

Bounce to disk or mix to disk is a rendering process that happens in real time. You have a number of different tracks of audio and maybe some effects and the total length is 5 minutes of audio? Your bounce time should be 5 minutes. Mixing of multiple audio tracks and rendering effects take some time.

Simple file conversion can be done more quickly than real time.

Yep, and Protools will ONLY mixdown with a bounce to disk... no faster than realtime with TDM.

Either, your background in video provides you with enough expertise to go off and do this process yourself for free, or it doesnt. If it doesnt then you will have to stick to the studios deal that presumably youve agreed to wherein theyve advised on the best way of getting to the end result.

There are 2 types of people in this world.
Those who wear suits, have meetings, then see who can actually do it for them -
and those who just do it.

Final Cut will export a wav or aiff file much faster than real time.

Protools will export a single file faster than real time, but not a mixdown.
Will Soundtrack do a mixdown (more than 2 files mixed together) faster than real time?

I know Sonar and Cubase will... don't know about Soundtrack...

With the new frequency editing (like Audition) and faster than realtime mixing (if it does), I might have to upgrade to the new Soundtrack Pro!

I started out as a DO IT guy.

Then, I wore the suits and attended the meetings for a year or two.

Never again.

Just hand it to me, and I'll DO it.

I am undoubtedly way out of my league here, but I am searching for this answer, "Why is my audio editing taking so long?"
For example, all I am doing is either highlighting and deleting what I don't want OR dragging and dropping what I do want.
I work at a good pace, but trying to put exact time into perspective, here is what I did today: for 2.5 hours I worked on the editing. I began at marker 1:02:22 on the original and at 34:03 on the one I am dragging and dropping to. When I quit, I was at 1:05:44 and 36:04 respectively. How can this even be possible? I would farm it out if I thought someone could do it for me at this point!
Any help will be quite hugely appreciated!

This is very subjective. There have been times where I have spent 30 minutes on a single edit getting it just right. Other times I can blast through many edits in a short time. I've just finished a rough edit of a podcast for a company where we recorded a roundtable discussion. The final rough length is 12:30. It took me five hours.

You did three minutes in two and a half hours. To me, that's not out of line, particularly, if you had to work with each edit to get what you want. If you're just starting out, you will get faster. It's best to know your editing application really well and be able to take advantage of your keyboard shortcuts, etc. That will improve your editing productivity.

Thanks for the encouragement, but I don't understand how most people are doing one hour of editing in two hours when I can't get through a few minutes. It just doesn't make sense to take this long. It is just an interview which I know well.

Describe what you're doing in a bit more detail. Do you have a transcript of the interview or a log sheet with edits marked? How many edits are there in an hour show? Are you doing really detailed edits like adjusting pauses, removing breaths and mouth noises, adjusting pacing, or just removing bad takes? Do you playback at 2x or 4x (or greater) speeds?

When I'm working from a script with marked edits, then I can move fast. Doing one hour of material in two hours is possible. It's really based on number of edits and whether you have to think about the edit. Making a simple edit where you delete a marked bad take should take 15 to 30 seconds. If you have to think where to make the edit, it will take longer. If you have 60 edits which take 30 seconds each that's 30 minutes. Of course you have to add in the time it takes to listen to the track and you also have to breathe.

Thanks, John, for your interest and help. I keep it simple. I have a few audios of varying length and merely want to delete the long silences or where a phone call came in the middle of the interview. I am also deleting out stutters or words repeated. I am only listening, highlighting, deleting.

Then I have also tried to speed it up by dragging and dropping what I want to keep thinking it might be faster. It still is taking just as long.

I am really stumped by this and frustrated because time is money which is flying in the wind right now. Thanks!

What editing application are you using? If I was removing a space in Pro Tools, I'd select the space by clicking and dragging then hit delete and Pro Tools would delete the space and suck up the ends to eliminate the hole. Same thing would happen with a stutter. Highlight the region from the first instance of the word to the start of the second instance of the word and hit delete.
