I hope I am in the right area.
I want to discuss various formats and quality and playability of various video inputs and issues with Blackmagic video card as a starting point.
Some helpful hints.
1) I am capturing from HDMI
Make sure that settings in “Control Panel – Blackmagic are set to HDMI
2) My first test was a HD Dish TV show of one hour.
using Blackmagic Media Express V 3.5.2 that came with card ( Very simple interface), however "Edit-Preferences", "video Format" to HD 1080i 59.94 since this is the only one thast works.
of the two "Compressions Types"
"Uncompressec 8-bit YUV" yields a file of 107 Gig
When editing output file with Sony Vegas Movie Studio Platinum the video clip was 50% longer than audio in duration.
"Compressed Motion JPEG" yields a file of 7.4 Gig
Whe editing this one the audio was 12% longer.
My next post if this is OK here will be the results of using Blackmagic Media Express V 2.03 from their WEB site that has more options and some I have found with better Sync.
I also will discuss Playback on "WD Live TV", various media players and DVD authoring of various renderings of the capture file from "Sony Vegas Movie Studio Platinum" and "Adobe Premiere Pro CS4"
Now down to my questions If this save file on my Dish USB Drive is only 2.2 Gig is there any quality gain in the larger "Compressed Motion JPEG"? Also why would one use "Uncompressed 8-bit YUV" to capture what was a compressed file on the Dish Drive?
