H.264 to ProRes
on Apr 2, 2010 at 8:55:03 pm

Hi -

Received several folders of video clips from a Still Photographer.

h.264
30 fps
640x480

Not sure what camera, assuming NOT Mark II because clips not HD.

I want to convert to ProRes before editing,
but so far haven't hit upon the right recipe.

ProRes same framesize/framerate = crazy shift when playing/parked on frame
ProRes 720x486 looks degraded stretched out.

Any ideas for best conversion settings would be greatly appreciated.
Thanks,
Jesse Gordon

Here's how I've done it. It works very well. Import the file to Compressor. Use an H.264 preset and change it to:

Audio Encoder
16-bit Integer (Little Endian), Stereo (L R), 48.000 kHz

Video Encoder
Format: QT
Width: 720
Height: 480
Pixel aspect ratio: NTSC CCIR 601/DV (16:9)
Crop: None
Padding: None
Frame rate: 29.97
Frame Controls On: It takes time, but this is important.
Retiming: (Best) High quality Motion Compensated
Resize Filter: Statistical Prediction
Deinterlace Filter: Best (Motion Compensated)
Adaptive Details: On
Antialias: 0
Detail Level: 0
Field Output: Same as Source
Codec Type: Apple ProRes 422
Multi-pass: Off, frame reorder: Off
Automatic gamma correction
Progressive
Pixel depth: 24
Spatial quality: 50
Min. Spatial quality: 0
Temporal quality: 0
Min. temporal quality: 0

Is it possible it was recorded using the 5D? Cannon released a plug in for FCP to use log and transfer to transcode to prores from H.264 using their camera.

Possible, but I would expect HD files from a 5D.
