soronsen squeeze jumpy in random places
on Aug 7, 2009 at 1:06:11 am

hey, i really hope someone can help me and it would be much appreciated.
Ive looked on the forum but cant find anything so im hoping its not a double post!

When compressing with soronsen squeeze it plays back amazing on the computer until a random place in the video were it goes jumpy and like skipping frames or something for a couple of seconds then back to normal...has this happened to anyone before? does anyone know how to fix it?

Thanks

MAC
Leopard 10.5
Exporting out of Final Cut Express as a quicktime file then importing into Soronsen Squeeze
HDV-.MOV in final cut express and .mov-.mov in squeeze so no change.
It is for internet playback

thanks

What Quicktime codec(s) did you use in your mov's and what settings did you use for those codecs?

when exporting out of FCE it was straight to quicktime movie so there was no settings to choose from.
It comes out as 1.76GB for a 3 min video.

Thanks

Ok, what settings did you use in Squeeze for your mov?

quicktime 1mps stream
sorenson video 3 pro codec
sorenson 2 pass VBR
10, 000 Kbps data rate (size came out at about 250mb which was good)
frame size 1280x720
frame rate/frames per second 1:1
bidirectional frames allow
key frames every 100 frames
auto key frames on scene change- frequent 100
image smoothing

thanks

Ok, we're getting there. 10,000kbps is way too high for Sorenson - and actually Sorenson is not suitable for HD frame sizes.

Any reason why you are using Sorenson?

What Mac are you trying to play it back on?

Im playing it back on my Macbook which is for sure powerful enough for it as i film with the sony z1 and the raw footage is fine in FCE.

Im using soronsen because i heard the compression was really good and been looking for something that produces a nice quality video.

Do you know of something that would work better?

thanks

Sorenson is pretty ancient.

Try H.264 in either a mov or .mp4. Depending on what the content of your video is there should be no need to go over 5000kb/s. Start at 100kb/s and work your way up.

(use AAC for your audio if you have any)

Thanks, I have used that in the past but for some reason i keep getting a ghost/double image effect with h.264 which is reduced by soronsen but still visible. anyone know why this is? its not the shutter speed when filming as its not visible in FCE when working on the project or when viewing from the camera and also filming between 500 and 5000 so it wont be that.

any ideas? thanks
