I've just exported a 9 minute clip from iMovie as H.264, 24MB/s, 1080p25, AAC@192kb/s. (1-pass)
It took....wait for it.....1H30!!
I'm using a 2.53GHz MacBook Pro 13, 4GB RAM, 9400M 256MB Shared Graphics.
Would a higher graphics card, better CPU (2.66-3.06) increase the speed much, or would it be a case of speed increase = 3.06/2.53 for 3.06GHz for example. So that 9 minute clip would be exported in 1H30 * 2.53/3.06
I understand Turbo.264 HD increases the speed of export drastically. If it can do it in even 1/3 of the time retaining the same quality that would be fantastic. If it could export that 9 minute clip in 9-18 minutes with the same quality, I would be over the moon.
That would mean the 5H30 of footage that will probably end up being around a series of 20 minute clips (probably 4-5 in total), could be exported in roughly 1H20 to 2H40. That would be unbelieveably quick from my perspective. If it could do it in less than 5H I would be just as chuffed.
I will keep this thread updated if I get it.
BTW I am probably going to have to, because if the resulting movie from the 5H30 is around 1H30 lets say, converting it with the computer would take around 15H or 30H+ with multi-pass.
If the resulting movie is 3H in total, 30-60H sounds a long time, especially if something goes wrong, not to mention the fact the computer will be practically unuseable during the conversion.
I don't know if you or your friend would be prepared to help, but if I upload some sample footage to a temporary mobileme account, would you be prepared to put it through Turbo.264 HD with the following settings?
I bought the Turbo.264 HD in the end, on a risk basis, from the Apple Store, who said I couldn't return it at all. The one guy in the store who had one said he used it with Final Cut Pro and it was quite good.
Well, I bought it and its brill. The image quality is identical to the original footage, the colours and sharpness are great and it encodes the files roughly 3x faster than my Mac CPU, still 2x realtime, but great nonetheless.
I would post samples but I wouldn't know how to send them to you.
