Yup, I’m getting frustrated. I don’t get why this is happening. It takes about 30min to encode a 4 minute video from 1080i60 HDV to 720p h.264. I’ve now done this export 3 times with absolutely no luck. Check out the screen shot from Quicktime:
So in the picture above you can see very clearly that 2 frames of video are merged in a macro-blockish sort of fashion. This is an encoding glitch. My intention is to upload this client video to www.vimeo.com to be shared with the world. But these flashes happen about every 10-15 seconds (randomly) making the video look absolutely amateurish. The 2 frames are nowhere near each other in the timeline and the “glitch” is approximately 3 frames long.My conversion process goes like this:
- Export video from FCP timeline to HDV QT file.
- Open said QT file in QT Pro and choose export.
- Choose QT options as follows (key frame rate= 30, bitrate=3000, codec=h.264, size=1280×720, letterbox if necessary).
- Let it export . . .
- Watch the glitchiness
I am on the latest version of quicktime and can’t for the life of me figure out why this is happening. It’s never happened on any video that I’ve ever exported using these exact same settings. Here are my next steps to see if I can find resolution. If anyone reading this can think of some suggestion - please let me know.1.) Try using compressor. I’ve had bad luck with compressor and vimeo, but I’ll gladly try it again.2.) Try a different video and see if the same settings have problems3.) Try a different key frame rate. I know sometime the keyframe rate can sometime cause macro-blocking weirdness, but it usually lasts longer than 3 frames. If any of these work, I’ll update this post. ——————Sweet. So it’s done, what I did is used compressor which took significantly longer most likely due to superior deinterlacing. The weird macroblocking disappeared. I still wish I knew why it was happening in the first place. But here is the video:
