Export Quictime file and maintain the file size and quality as the original.

[Cole]

I shot some footage for a client yesterday and ran into an issue. To make a long story short I have QuickTime mov files shot with my Panasonic GH4 that have a buzzing sound in the audio track. I have clean audio from a recorder that can be sync'd. Is there a way for me to do this for my client and deliver them as the same QuickTime file but with the clean audio and maintain the same file size and not have quality loss in the image?

If so I will probably put all of the spanned clips together from each interview and sync the audio before delivery. I am just not sure which codec will give the client the same quality footage compared to the originals and not have a massive difference in the overall file size.

If anyone has experience with this it would be greatly appreciated.

Thanks,

Cole

I would give it all to the editor and let them handle it.

I kind of figured but it was worth a shot.

Thanks.

I don't have any direct experience trying to match GH4 quality/file size...but...I can offer some suggestions for high quality QT codecs.

Quicktime Animation is very high quality but probably will increase file size. you should render a test file to confirm.
Quicktime Prores LT (light version of Prores 422 I believe)
Quicktime Prores 422 - this is high quality codec and will probably increase file size. GH4 footage is 420 color space.

Here is a article on the different verities of Prores

You should render a test file to confirm if these codecs meet you needs. Good luck!
