How to Downconverter DVCPRO 720P25
Hi, I use KONA 2 with my dual 2.5 Ghz. OsX 10.4.2 and Xserve RAID 5.6 TB.
Now i’m working with a project 25Fps. shooted with panasonic VARICAM and edited with Final Cut Pro HD 5.02
I can’t Downconvert my project in SD because it’s only possibile with the KONA control pannel to downconvert 720p59,94 in 525i (NTSC) so for the moment I have created new project in SD 625i 10Bit uncompressed and I have rendered all material HD in SD format but with poor quality result…!!!
Anyone Know better solution to Do that!
Thanks In Advance -

Hi Marco,
Are you sure your 25fps Varicam footage was shot with the camera switched to 59.94hz, and not 60hz? The way to check is by using the userbits reader on your replay deck to check the data off tape. If the last 2 digit number on the display starts with a 5 then yes the footage was shot with the camera system frequency set to 59.94hz thus making all it’s frame rates derivitives for NTSC usage. If the last 2 digit number starts with a 6 then the camera was set to 60 hz and all frame rates are PAL derived. Don’t assume that because the tape is running at 60fps that all the footage is always NTSC. The Varicam is a multiformat camera and all shoots must be planned out with all aspects of post in mind because of this.
FYI on the user bits panel the 3rd set of 2 digit numbers will be stationary when the tape is played and will tell you the frame rate the camera was cranking at when the footage was shot. -
Hi, matthew
I Know that and my shooting was set to Freq. 60 Hz. but the problem is another one….
If you look in the KONA CONTROL PANNEL when I use for native format 720p60 isn’t possible to Use Downconverter box all text is gray…..
If I use 720p59.94 the only possibility is downconvert to 525i (NTSC)…. Only with 1080i50 can I downconvert to 625i…..
Thanks In Advance
