I’m traveling right now so all I have is my PC laptop. I have an 18 minute 10FPS VGA Quicktime MJPEG movie, which I want to somehow speed up into a 30FPS 6 minute VGA movie (of any format/codec) and add a 6 minute MP3 as a soundtrack. I know this is possible and fairly easy if you’ve got the right tools but all I’ve got is FreeDV and that always wants to spend 10 hours importing the quicktime movie.
So is there any easy way that would do this without uncompressing/recompressing the stream?
If you are willing to buy QuickTime Pro (about $20 USD) then you should be good to go. It’s not a download, just a key so it sort-of meets your requirements.
Load your current movie, click File -> Export. Click Options. Click Settings. Set the Frame Rate to 30fps. Set Key Frames to auto (May be unavailable depending on the codec you choose). Set the compressor as you see fit.
There will be an option for Audio. If you select this then you should be able to set a new audio track. I can’t give you a precise answer to this part as I don’t have a QT pro on this machine. I have done something similar to this in the past so it’s not beyond QTPro’s ability.
I can’t guarantee that this wont do a recode - it depends on your codec choices. If you keep to the same codec you should be lucky as the audio stream is seperate to the video, so it will just re-interleave the data.
Convert it to AVI using Bink
Change the framerate and dub over using VirtualDub
If you haven’t already got it, I would also first install the HuffYuv codec - it’s a lossless video codec with great compression - and I would choose that codec when converting the Quicktime to AVI.
