So, it is looking like a corrupted Premiere project file to me….can anyone offer any comments or advice on whether they think it is a corrupted project? It gets more confusing in that I can Dynamic Link to Encore, transcode it in there and all the colour correction and effects are encoded….but not the whole sequence, only about half of it. None of the above are encoded into the output video so all I get is the untouched colours and no effects but all the shots! Okay okay I think I may have gone someway to finding out what the problem is here….it isn’t just the matte sequence that isn’t encoding….it’s all effects and colour corrections I have to all the clips! I have tried the 3 different methods for encoding to include the Alpha channel as per Adobe ( ) – which should therefore pick up and encode the whole shot including the track matte(?) – but with no joy!Īm I doing something wrong here – I am fairly new to this and this is the first time I have attempted track mattes so I stand by to be corrected. It is set as ‘Reverse’ and I have used ‘Matte: Alpha’ from the track matte options menu, as per the Adobe guide. The matte itself is a black ellipse I created in the title generator and I have put this at the top of a three part stack, underneath this is the superimposed shot (which is just a darkened, black and white version of the background shot, so I can highlight in colour, a small part of the background shot for a couple of seconds). Whatever format I use in Adobe Media Encoder, it just will not encode the full shot with the Track Matte displayed, only the background shot is displayed. I can also easily export a single frame of this shot as a TIFF with no problem.

I have set up the matte correctly (track order) and it plays perfectly in preview. I am having problems encoding a short 14 second sequence which contains a 4 second shot into which I have added a Track Matte.
