Thread: More Codec performance test

  1. #1

    More Codec performance test

    60 different codecs and compression settings on 3 different single drive systems.
    Playback is on 1 layer only. Results do not scale to multiple layers
    NOTE: System disc is NOT the drive disc.

    Tested
    Single Raptor 74GB
    Single 10k SCSI Atlas iV
    Single 15k SCSI

    Results:
    Different drive Systems are pretty similiar.
    10k drive is not slower than 15k drive.
    Raptor is slower at uncompressed data - but pretty similiar with compressed codecs. ( Blackmagic codecs are uncompressed )
    Single layer 25fps playback of 720p footage is possible with:
    photojpeg 50% & 75% and mjpegA 50% & 75%

    Single layer 25 fps playback of 1080p footage is possible with
    photojpeg 50% and mjpeg 50% ( just )
    and marginally at photojpeg 75% and mjpegA 75% ( just )

    4 layer playback tests now includes dual raptor

    60 different codecs tested playing back 4 layers of the same type of content

    tested on internal drive
    internal raptor 74GB
    scsi 15000rpm Maxtor Atlas 74GB
    scsi 10000rpm Maxtor Atlas iV 140GB
    dual raptor - firmtek card

    Results

    Internal drive is very very bad.( and these figures are just averages - not deviations, the internal drive has poor consistency ).
    Raptor, and scsi 10k and scsi 15k have close performance.
    scsi 10k is slightly faster with some codecs.

    Only dv-ntsc will give close to 30fps performance on all 4 layers.
    DV-NTSC is slightly faster than DV-PAL- the difference is important

    These results are a little geeky.
    Ill try and find to way to present them which makes more sense.

    Single and Dual raptor side by side

    Single and dual raptors same files.
    4th layer complete time

    dual raptors have slight edge with dv codecs.
    Not much in it.

    Just wondering why DV PAL only makes an appearance at 50%

    Cheers

    DV-PAL and DV-NTSC have no quality settings.
    Their compression rate is fixed, and unchangeable.
    50% is just a convention.
    Its not really 50%

    Thank you

    Richard,

    Thank you for this very valuable and obviously painstaking information. It must have taken a very long time to compile all of this.

    I'm just curious, what was the media you used for this? What clip was it?
