Exporting film with a Lossless codec speeds up title fades?
Hi there,
I’m trying to export a Lossless version of a short film I have made. I exported with an animation codec and all is fine except my credits at the end fade in/out very quickly when when viewed within Premiere Pro CS5.5, they fade in/out nice and slowly as wanted.
I also tried exporting as a PNG Quicktime but the same thing happens. When exporting using the Vimeo preset, the fades are fine. I have tried exporting through Premiere Pro itself as well as through Adobe Media Encoder. Please see video of sped up fades attached.
Anyone know why this might be happening? And whilst I’m here, can anyone suggest good, lossless export settings?
I’m also looking for the best way to get the video onto Vimeo. At the moment, if I use the vimeo pre-set and increase the BitRate to the amount allowed without exceeding 500mb (Vimeo upload limit), I get terrible banding in some scenes. Does anyone have any advice on this?
Any help to any of these questions would be greatly appreciated!
I’m using Premiere Pro CS5.5 on a 2.4GHz Intel Core i5 mac. Memory: 8GB 1067MHz DDR3.

Between you and me, not a bad look… most people abuse my patience with fading titles 🙂
Are you using card specific dissolves (as in Blackmagic dissolves, etc ?)

haha glad to hear it.
I’ve actually created the title fades by using keyframes on the opacity line. It’s only just occurred to me to try using a dissolve pre-set instead!

I’m thinking because animation and PNG sequence include an alpha channel this is leading to your issue since most playback apps including quicktime can’t playback alpha channels properly & vimeo probably doesn’t convert them properly either. In your final PNG sequence the black background isn’t actually black, but transparency, so when a title dissolves away it is actually the alpha channel “fading up”, but since the app(or vimeo convertor) can’t playback the alpha channel properly, it will fill your text to 100% “opacity” at all transparency values except 0, which is why there is one black frame between titles. I bet if you put this PNG sequence back into premiere or after effects it would play properly with the fades.
As for format I’ve been fine with the h264 vimeo presets for the most part, if you’re getting artifacting between scenes perhaps try unchecking “key frame distance” in the advance settings on the video tab when exporting, this has helped with some glitches for me in the past.

Thanks very much for all the info! I ended up replacing the opacity key frames with the ‘dip to black’ transition. Not sure whether the problem was to do with the alpha channel thing or not but it seems to have solved it!
Will have a fiddle with the key frame distance on the export and see what I can come up with. Thank you!
