Compression Tips

I felt like posting this because I am bored and just watched an interlaced movie on the internet *cringe in horror*

Here is a good compression method that has unnoticeable quality changes and compresses footage by about 100x.


1) Export your footage from your editor in lossless/uncompressed avi.

2) Pull the clip into Adobe After Affects, de-interlace your footage, and then export in lossless/uncompressed avi. It doesn't have to be AFX, just anything that can de-interlace.

3) Grab your de-interlaced footage and place it into Quicktime Pro. Export the clip with the following settings:

Video:

  • Compress with H.264

  • Keep the current frame rate.

  • If you shoot NTSC then keyframe every 150 frames.
    If you shoot PAL then keyframe every 125 frames.

  • Keep the data rate automatic

  • Keep the quality at about 70

Audio:

  • Format should be AAC and the channel should be stereo (L R).

  • Put the rate 32 kHz and check off advance settings.

  • Keep quality at normal.

  • The bit rate format should be at Variable Bit Rate.

  • The target bit rate should be at 128-146 kbps.

  • There shouldn't be any precedence.


Thank you for taking the time to make your footage look good.
