i am making a video and i would like the background to be clear when its exported so when i have it playing, you dont see a black square around the video where the clear parts should be (ps im using hitfilm 2 express)
Basically, three things are required to do this.
1. Make sure you have the transparency you want properly embedded in your timeline. Note that adding a Key filter to a piece of footage doesn't directly alter its alpha channel and create transparency, until the clip is embedded in a comp. The same applies to masks.
2. Export to a format that supports alpha channel transparency. AVI Uncompressed or PNG image sequences, for example.
3. In the Export settings, make sure you have the color depth set to 32-bit RGBA, so that it will include alpha channel info.
I think that should do it.
Let us know if you're still having trouble here @n123q45 - but it looks like Axel has probably solved the issue
Last note. Once you have rendered the video with a transparent background you'll need to check it by bringing it back into an NLE and putting something undee it. If you view the video in a media player it will still appear to have a black background.
I will test it soon, thanks
I want to do the same thing, but i still can't....
How do you change the color depth set to 32-bit RGBA?
And is Uncompressed the same as AVI Uncompressed?
That reminds me...
Can Hitfilm 4 Pro import image sequences?
I tend to render from 3D Animation software to png image sequences. Can I import those natively or do I have to keep importing them into Sony Vegas Pro and render to a video file as i'm doing now?
@Karma yes, there's a small arrow next to the Import button. That's a pullout menu which should include "Import Image Sequence." Open the folder (which will appear empty) and hit OK.
Ty sir. That now cuts out Vegas Pro almost entirely.
Catfishowo - HitFilm only has 8-bit Integer and 16-bit Float which can be accessed from the Project Settings page. And yes, AVI is uncompressed and the settings for that are on the Export Settings page.
karma - HF4P does have the capability to import PNG image sequences. You should be able to import them from the Import button and is listed right under 'Media'.
@StormyKnight oops, I missed @Catfishowo 's question and you misinterpreted it.
Catfish, not on OC now, so working from memory. In Uncompressed (yes, AVI), PNG and OPEN EXR Export settings there should be a dropdown menu near the bottom of the tab. It might say Color Depth or Color Channels. Anyway, it will say "RGB." Change it to "RBGA."
Stormy, bit depth is an annoying metric. "16-bit" color depth in a project is using 16-bit precision math to calculate color bit values internally, but 32-bit depth export refers to three 8-bit color channels (RGB) and an 8-bit alpha channel (A). English is annoying that way.
How do I add a photo with a transparent background?
If its just a single photo, @JoshBuxton, then just use the standard Import control from the media panel. The alpha channel will be detected automatically by HitFilm. If the image is part of a sequence, then you can use the Import > Image Sequence command.
I am trying to save a series of .png files as a looping GIF basically and when I exported originally it works perfectly, but it is not transparent and the right size.
I know that I want "Source" size and also I saw where everyone says click "Avi Uncompressed" and with "Alpha" ... I cannot do that. It only allows me to choose from .mp4 or .mov as the export presets. Can someone please help me, do I have to download a special preset somewhere? Thank you
@JordanSadler I am not 100% certain that GIF supports alpha and will have to check on that, but MOV and PNG sequence does. The only reason I can think of why you can't select AVI with alpha is "possibly" you are running the DEMO version of a PRO or an unactivated EXPRESS version, but that is a reach on my part. Hope this helps a little.
