Copy Left Audio to Right for "Stereo"

Hey everyone,

Need your help.  I have a project I'm working on right now.  Audio was recorded with lav mics into a Zoom h1 recorder.  Not sure if setting or the lav mic is the issue, but it only recorded on one side of the channel, e.g. left. It's not that noticeable when using straight up computer speakers, but very noticeable when using headphones.  Is there a way to mirror the left channel to the right in hitfilm?  Or do I have to use an outside program if possible?  What program may that be?

    My suggestion would be convert to a mono track with Audacity. (Free)

    http://www.audacityteam.org/download/

    Quick tip on converting to mono here:

    If you need to convert back to 2 tracks just do a search for "audacity convert mono to stereo" and you should be back in business.

    Happened to me as well. I was using a lapel mic too, but maybe it wasn't correctly plugged in... One track had nice sound, the other one was barely earable (is "earable" an English word?). Anyhow...

    DON'T convert stereo to mono, as this will average both tracks into one, meaning you'll end up with a single track with half the audio level of the good one!

    Instead, separate the tracks to stereo (drop-down menu in the box at the beginning of the track), select the track with the good sound, copy and paste onto the other track. Check if  one track is set to "left track" and the other one to "right track" (should already be that way), and "join to stereo". Done.

    I'm not sure I gave you the exact words for the menu, as my menus are in French, but I hope you get the idea

    @VobbleWobble There always several ways to skin the same cat.

    In my "other editing program" I use a pan channels feature to duplicate, say the left channel, to the right so that both tracks are identical.   But as @Cervier has pointed out, I have to boost the level to get that back up to the original (which really was never a problem as long as the audio is clean).

    Cut and paste is a good way to go, though.

    I still recommend having Audacity in your toolkit.  Just handy to have.

    @stargazer54 @cervier

    Thanks friends! Very helpful, I remembered I had a free audio editing software with my zoom h4n (wavelab le) which makes it pretty easy as well.  Thanks!

    As a professional, but new user of  HitFilm Pro. This is a basic audio tool that needs to be included.

    @Hitfilmer272610 Almost as badly as Hitfilm needs compressor/limiter effects.

    Something like this maybe. I believe I suggested this for a new audio effect/other.

    I'm having the same issue as well with HitFilm 2017 Pro.  I have 400+ shots with audio only on the left channel.   Using Audacity to add audio to the right channel and then syncing them in HitFilm would be a nightmare.   In the past I used Premiere's "duplicate left" effect to easily fix this issue.  I don't want to go back to Adobe, but at this point I have no choice.

    Having the same problem, and this just needs to be there. When doing interviews with one channel for shotgun mic and another for a lavalier, i need to be able to choose which channel i want to use.
    This REALLY needs to be added ASAP

  • WisseSWisseS Website User Posts: 2

    Same here. I am thinking of using Hitfilm for my students. Massively changing the way they are introduced to editing (away from PPCC), but without this function this is simply a no go software, since it cannot be used for interview, where one uses a second mic.

    Can anyone from Hitfilm reply to this?

    FXHOME staff never comment on which new features are going to be added to new versions, but they're always open to suggestions. Head over to the wishlist thread and add your request.

  • HitFilmer296228HitFilmer296228 Website User Posts: 4

    I added this to the wishlist a while ago but that list is VERY large.  HitFilm does so many advanced effects I would think this is a simple update.  Take the right audio channel and replace it with the left (or the other way around).  I'll keep waiting.... because I really want to switch over.

  • HitFilmer296228HitFilmer296228 Website User Posts: 4

    Almost 2020 and I'm still waiting for this feature.  Every time there is an update I get excited this fix/feature might be included.   Hopefully soon, but I'm starting to doubt it's on their radar.

    Still unable to manipulate the LEFT and RIGHT channels.  I though perhaps this could be resolved by allowing the user to copy the track, reverse the left and right outputs for that channel, and then it would work perfectly.  I have been experimenting all afternoon with no luck so far.  Am I missing something?

    @TheBenNorris nah, Hitfilm will support stereo channels, but there's no way to map a stereo file to mono, or map one channel of a stereo file to mono.

    @Artejal no way to do this in Hitfilm, currently. You'll have to use external software to remap the audio then use Hitfilm's audio synch to lock everything up again. Audacity is free and cross platform if you don't already have an audio editor.

    @Triem23 you're correct, I've no idea why I thought that wasn't the case. Deleted my comment to avoid confusion.

    @TheBenNorris you were probably thinking of surround. Hey, it's early on Monday morning. Have some coffee. :)
