analog vs digital capture File size differences?
 
Hello all!

Scenarios:

a) 1-> (Scenalizeer) Analog capture drom VHS to to DV2 avi at 740x576. 2-> Load into premiere and do some editing. 3-> Export 704x576 and blur filter with VideoServer.
4-> Compress with TMPEGENC and KVCDx2 PAL templates. (704x576 CQ50 and strange matrix!!)

Results: 111 min -> 1.2 GB. Dont fit on 80' CDR!!!

b) DVD RIP. SmartRipper -> DVD2AVI -> TMPEGENC and KVCDx2 PAL templates (704x576 CQ60 and strange matrix!!)

Results: 104 min -> 802 MB.

¿Why analog compress its over digital compress in spite of less quality analog source compresión? ¿Anybody can help?

Thanks.

Was your analog capture a full screen capture?
Maybe that's why.

Oh yes, i dont know how to do of other way. Maybe you mean the capture resolution. My DV500+ capture card cant capture at other resolution.

Full screen videos have more visible pixels than a wide screen 16:9 ( with black bars ).
That's why the file size is larger.

The templates work best with 16:9 videos.
With full screen, you might get 90 minutes or so in a 80 minute CD-R.
