Is there any way to save an h.264 file at a higher bitrate than 16? I'm submitting a film to Prime and they suggest 30.

Thanks,
Javier

Type in the value you want into the H.264 settings. Here's the relevant section of a MediaInfo report on a test that I just ran after typing in 30 Mbits for the bit rate.

Format                                   : AVC
Format/Info                              : Advanced Video Codec
Format profile                           : High@L4
 ...
Bit rate mode                            : Constant
Bit rate                                 : 30.0 Mb/s
Width                                    : 1 920 pixels
Height                                   : 1 080 pixels

The only thing to be aware of when you do that is that the next time you need to export you will have to type in that value again. It will reset to the default maximum the next time that you use it.

Great, thanks. I tested at 16 and 30 and can see the difference in file size.

I also tried the same export with a variable bit rate setting. The maximum was 30 Mb/s, average 20 Mb/s and minimum was 8 Mb/s. This is what I got.

Format                                   : AVC
Format/Info                              : Advanced Video Codec
Format profile                           : High@L4
 ...
Bit rate mode                            : Variable
Bit rate                                 : 20.0 Mb/s
Maximum bit rate                         : 30.0 Mb/s
Width                                    : 1 920 pixels
Height                                   : 1 080 pixels

And yes, the file size does change, so it's obviously doing it.

If you get tired from keying-in the values above maximum defaults after a while, you can save the settings as preset.

But, please note: Do not open the bitrate-setting after selecting such a preset prior to exporting, otherwise not the keyed-in values, but the maximum defaults are displayed and used. The only way to check if the settings are properly saved is exporting the video and checking with Mediainfo.

Ah o, I used cbr but amazon recommends variable, it didn't seem to let me key in, I'll try again. Thanks!

As a matter of interest, do you publish on Amazon Video Direct?

Yes! I had submitted a short film last month (17 minutes) and just yesterday I noticed it was accepted and had generated some views. So I'm preparing a few others I have. The first one I submitted in yuyv because I didn't have the editing project or anything left, just that copy and it was accepted.

Everthing I've done so far is in lightworks but I plan to learn resolve to have a second option for editing. (I'm still a bit of a newbie)

I tried to watch it here in Germany with Amazon Prime, but I see this:

Any chance to fix, without much effort?

Yes! I'm going to have German captions made. It's only US/UK right now. Whereabouts in Germany? I lived in Berlin for a short spell. It was great but too cold and snowy, like where I grew up back in Ohio.
