Exporting a small size file 1080P with 24 bit

[shayf97832901]

Just finished scanning the web for a solution for this one...

I'm starting to lose faith...

I'm working on a music video clip for youtube of a soundman friend, who complains that the export settings I chose (normal H264) really flattens the sound he created...

Does anyone know what combination of format and codec will open the option of choosing 24 bit on a 1080p video, while keeping the file size under 1 gigabyte for a 4 minutes clip?

H264 gives only an mp3 quality and QuickTime uncompressed exports it as 37-gigabyte size file...

Thanks a lot

Use ProRes or CineForm instead of uncompressed and upload that file to YouTube. I am pretty sure that they will not keep the audio @24 bit when they compress the file though.

Those goals may be at odds.  Better quality normally means larger files.

You may want to drop the size requirement.

Having said that, both Cineform and DNx allow for 24 bit Uncompressed audio for best results.

Thanks a lot Averdahl and Jim Simon !

I've managed to export 1080p with 24bit using gopro cineform as the codec, and the file size came out to be almost 2 gigabyte in the lowest quality (1 out of 5) which is still reasonable for my purpose.

Having said that, I still don't know why there isn't an option of exporting a smaller size file with the full quality of the audio, as the audio file is only around 100 megabytes... I wonder what are the standard settings for a music video clip for the web?

Standard for video on the web is most of the times 16-bit, 48 Khz, sometimes 16-bit, 44.1 Khz. (CD is 16-bit, 44.1 Khz)

If i use the TMPGEnc Movie Plug-in AVC for Premiere Pro i can get a H.264 file with 24-bit audio if i export it for Blu-ray. Worth trying maybe.

Fantastic! Thank you very much, I'll try that

From the big artists, I would expect excellent quality for both picture and sound.

A Cineform file with Quality 4 would do the job.  Why the artificial size requirement?

[shayf97832901]

The 37-gigabyte uncompressed file I've exported, barely played on my computer, and I just assumed that very big files would be too heavy to upload to facebook and youtube...

Uncompressed will be much larger than a Cineform file.  I don't recommend that option, as Cineform Quality 4 is "visually lossless".
