I have a sequence of PNG-images with transparency which I want to convert to an FLV video with transparency.
So far I have been using ffmpeg to create FLVs (vp6a
), but it doesn't seem to support alpha channels.
The only software I found so far is Adobe After Effects, but it is too pricey. And then there is Adobe Flash Media Encoder, but it can only encode live from devices and not from file.
So is there an open source alternative that can create FLVs with alpha channels?
thanks, but i am looking for a free tool that can create FLVs with alpha channel (VP6a codec) – clamp – 2010-08-31T08:27:48.633
@clamp: Then go ahead and download VP6 from http://www.free-codecs.com/download/vp6.htm. Google bought On2 Technologies and released it to the public. Actually, there are also VP7 and VP8, but I haven't looked into them. VP6 sounds good enough from the description.

@clamp: See my edit. I am also not sure that the link in my comment doesn't also contain vp6a. – harrymc – 2010-09-01T09:34:38.983
The K-Lite Codec pack is mostly for decoding, and only does encoding to a small number of formats. I don't believe VP6a is one of those. – Simon East – 2011-05-13T05:30:22.113
@Simon: Correct. K-Lite supports encoding in VP7, not VP6. On2 has now released a free version in VP6 6.4.2.0.
