If I select in setting for the project Audio 24000 Hz
It stops with
!"Could not initialize the AAC encoder (Error 33).
!"Process finished unexpectedly"
If I select 32000 or higher there is no issue.
AAC sample rates and bit rates have to be within a 6:1 or lower ratio. Put another way the maximum bit rate allowed is 6 times the sample rate.
6 x 24,000 = 144 kbps so you have to set the bit rate to 144 kbps or lower before any AAC encoder will work. HitFilm doesn't have 144 kbps as an option so you'll have to go with 128 kbps.
6 x 32,000 = 192 kbps which just happens to be the HitFilm default so that's why 32,000 worked for you and 24,000 didn't
Thanks for the reply.
Do you mean the sample rate of the audio that is contained in the video edit or just that HF doesn't support exporting below 32k?
Ummm neither one?
The sample rate and bit rate are intertwined. A lower sample rate lowers the the maximum bit rate allowed. HitFilm can export to AAC audio with a sample rate below 32,000 but you have to manually lower the bit rate in the export panel to something at or below the maximum dictated by the sample rate.
HitFilm defaults to 192 Kbps. This bit rate is too high for your project's 24,000 sample rate so you need to manually lower it. The maximum bit rate allowed for your sample rate is 144 Kbps. HitFilm doesn't have that as an option so you have to choose something lower like 128 Kbps. Now your project will export at the 24,000 sample rate.
The alternative is to set your project sample rate higher. HitFilm will then resample any audio with a lower sample rate to the higher rate meaning if your project sample rate is 48,000 and you import something @ 24,000 it will get resampled to 48,000.
Doha, my bad.
Couldn't see anywhere where to change that on 2017 hence my previous post but now you reminded me what it was like in Pro 4 I found the answer.
I need to edit or create a pre-set and select that before I click the export icon.
Still a good post on the original error to put something in the documentation or error search on forum.
Thanks again for your help and time.
@Datus My bad too I just assumed you were using Express. Sorry about that
Dropping this here for future reference.
Hitfilm can render 44.1 to 384Kbps. Vegas will let you render 32Khz up to 384Kbps. Vegas does clamp the max AAC bitrate based on the output sample rate.
I believe the max bitrate being reported is per channel. So stereo is twice the reported value.
In your showing of changing kbps, how do you actually access that menu to change the kbps? I am new to using Hit-film, and I can't find any videos on how to do it. If you could help me that would be much appreciated. I am using Hitfilm 4 Express.
@Manic005 this video contains absolutely everything one could ever need to know about Import and Export from Hitfilm's 4 and 2017.
Btw, Hitfilm 2017 is out and free if you want to upgrade.
This video discusses how to optimize your footage before import into Hitfilm.
@Triem23 Thank you so much!
I am using hitfil express 2017 .. I am exporting my composite shot in dv- pal option ..it is perfect in pc to see .... But iam unable to see in my mobile phone (android)
Please help ... I am getting heak ake during exporting my video..... Say how export video into mobile supported format
@anandavinnyharris use an export template for YouTube instead. Android phones don't read "DVD" files.
