I'm trying to export a 2 hour feature film in 4K. Please help!

Hello everyone,

I'm Nirav.

I'm trying to export a feature length film in 4K.

Running time- 2 Hours.

System Used-

Dell Insipron Gaming Desktop 5675

AMD Ryzen 7 1700X Eight Core Processor  3.4 GHz

RAM: 32GB DDR4 2400MHz

256GB SSD

1TB Harddrive

My question is how big should the file size be for 1080p HD and for 4K in the export settings?

I'm using Premiere Pro CC 2018.

Hi Nirav,

it's not really a question of file size, but more of what formst you need for the boradcast.

For instance, if your feature film is to be broadcasted in theaters, you will probably have to export a 2k or 4k DCP, which will be a very large file, whereas if it's for On Demand Streaming, you will probably encode it in h264 which will be smaller because more compressed.

The best thing is to ask the delivery platform what file format / codec they need your film to be delivered in.

Hope this helps,

Seb

Thank you Yenaphe,

I shot the entire film in 4K DCI (4096:2160) @24fps. Aspect ratio in premiere was set to 2.39:1.

Therefore in my export settings, it is 4096:1714 for 4K, and 1920:802 for full HD. Right now my biggest concern is just exporting in full HD because I want to register for film festivals and will need to send them a copy. I just don't know how big should my file size be set at to export it. Also, should I export it to the HDD or SSD drive on the computer? The run time is EXACTLY 2 hours.

Nirav.

Ok, I understand better your needs.

What I would go for, as a lot of festival will require a link to a platform such as Vimeo or Youtube, or a direct link to your file hosted on ftp, here are my recommendation:

For the 4k version:

h264 High Profile 5.1 - vbr 2 pass  - 10 mb/s with 20mb max

For the HD version:

h264 High Profile 4.1 - vbr 2 pass - 7mb/s with 14mb max.

You will find all these parameters in in the export menu and Adobe Media Encoder.

Hope this helps,

Seb

Thanks, Seb.

I will definitely try it and post on how it goes.

[niravg94621866]

Seb, thank you for the feedback. It worked. I was able to export at full hd in about 4 hours.

HOWEVER, the entire film is INTERLACED. I exported at progressive. Do you know why this must have happened?

If it is for a festival you need to ask the organization, as to format and filesize

To play it safe I would set it to 1920x1080. 1920x802 will also display black bars on most festival screens.

[niravg94621866]

Thank you Ann Bens.

Yeah 1920x820 would work too if I decide to opt for a 2.35:1 ratio.

[Ann Bens]

YOu can still keep that ratio with 1920x1080.

[yenaphe]

This is strange. Is any of your footage interlaced ?

[niravg94621866]

Actually I figured it out. I had to check the "Deinterlace" in the export.
