Ok, tried Rendergarden, it doesn’t work for me, I render from a script and there’s no way (at least that I know) to plant the seeds and avoid Rendergarden dialogs.
[Tero Ahlfors]“Rendergarden etc. does have a feature that will automatically transcode the image sequence to a single file. Or you could set up a watch folder.”
I didn’t know that Rendergarden have such feature, do you know if I can get the final render in .mp4 automatically from rendergarden?
It is really not that easy. Royalty-free licences doesn’t fit my requirements, I need non-copyrighted audio files or specific licenses that allow me to include the audio files into free and paid videos (we offer free video previews to our clients, then if the client is happy he pays for a high quality and non-watermarked version of the video).
You could do it in Photoshop, make the left half of the spectrum with a line and curves, and then mirror the right side by copying/paste/flip horizontally so it’s perfectly symmetric, then import to AE.
