Videokompressor MPEG2 eller lignende

[henke]

Jeg trenger tips til en videokompressor for Mac som komprimerer video raskt til små filer med minimalt kvalitetstap. Har blitt anbefalt MPEG2, men finner ikke dette i export-menyen i Final Cut Express. Noen tips til hvor jeg kan få tak i en MPEG2-kompressor - gjerne som kan legges inn i Final Cut - eller noe tilsvarende?
Det må gjerne være shareware

Mpeg4 er vel strengt tatt å foretrekke til slikt og ikke Mpeg2, dog krever det litt kraft om det ikke skal bli tidkrevende.

Kjøp deg QuickTime Pro.

Eventuelt, for å kunne lage en batch av filer, kan du tenke på å kjøpe VisualHub.

Dette er noe vi fikk av en av lererne vaare paa filmskolen min. Haaper dette hjelper;

Export 1 : Master

This will create a MOV using the DV codec which will be the same frame size and specs of the original camera footage - ie PAL DV Widescreen

- Choose FILE > EXPORT QUICKTIME MOVIE

- Chose a Location to export to.

- Where its says SETTING choose DV PAL 48K ANAMORPHIC

- SAVE

Export 2 : h.264/AVC Hi-Res

This will create a compressed but full resolution high quality export that is much smaler in fiel size than the master. This will be the one we will use for Screening.

- Choose FILE > EXPORT QUICKTIME CONVERSION

- Chose a Location to export to.

- Where its says SETTING choose QUICKTIME MOVIE

- Choose OPTIONS > SETTINGS

- Where its saids DATARATE select RESTRICT TO and enter 2000 (kbits/sec)

- Press OK

- Go to SIZE and where it saids DIMENSIONS choose CUSTOM and then enter 1024 x 576
(DV widescreen is 720 wide with a pixel aspect stretch of 1.422:1. If we times 720 x 1.422 we get 1024. Therefore 1024 is the Square pixel equivalent of DV windscreens rectangular pixels. 1024×576 will look exactly the same as 720×576 with a Pixel stretch of 1.422:1)

- Click DEINTERLACE SOURCE VIDEO and press OK

- Sound settings should read 48,000hz 16bit Stereo. This is fine (uncompressed audio)

- Press SAVE

Export 3 : h.264/AVC Online Lo-Res

This will create a compressed and small version of your video for online download delivery.



- Choose FILE > EXPORT QUICKTIME CONVERSION

- Chose a Location to export to.

- Where its says SETTING choose QUICKTIME MOVIE

- Choose OPTIONS > SETTINGS

- Where its saids DATARATE select RESTRICT TO and enter 500 (kbits/sec)

- Press OK

- Go to SIZE and where it saids DIMENSIONS choose CUSTOM and then enter 400 x 225
(this will keep the 16:9 widescreen aspect but at a scaled down size about half the original size)

- Click DEINTERLACE SOURCE VIDEO and press OK

- Where it saids SOUND click SETTINGS. Where it saids FORMAT choose AAC (this is the audio equivalent of h.264/AVC and is much like Mp3 audio)

- Where it saids RATE it should read 48k

- Where it saids TARGET BITRATE CHOOSE 128kbps

- Press OK
