Heres what Im trying to do: We have been working on a PC Leitch Velocity Q NLE system for the past couple years and just got 2 new Matrox Axio LE NLEs with Adobe Premiere Pro CS3. We are trying to get all our old projects from the Velocity system onto our Matrox systems and not sacrifice any of the video quality. I've been thinking that the best way to do this is by compressing old projects to AVI format from the Velocity system and move them over to the Matrox using an external hard drive.
I was actually able to bring in an AVI from the Velocity system onto the Matrox yesterday using the same Velocity settings below, except that I changed the aspect to 720 x 480 and the audio sample rate to 48,000. When playing the video on the timeline in Premiere the video looked great on my computer monitor but on my external NTSC monitor all motion in the video looked a little jerky as if frames are missing. I tried importing the test clip into both Matrox uncompressed 8-bit and uncompressed 10-bit projects and had the same resulting jerky looking video. Even after rendering the clip the video looked the same. Then I tried exporting the clip to mpeg using the Matrox media encoder but saw no change in the jerky movement. Here are my project and export setting for both systems.
The AVI was made on a PC Leitch Velocity Q NLE system. My project settings on the Velocity system are;
29.97 drop frame
720 x 486 24 Bit
Interlaced field order B
Sub pixel off Cropping off
44 / samples / second
Export settings are; (These are the settings I was trying the first time that didnt work. All I changed the second time was the aspect ratio to 720 x 480 and the audio sampling rate to 48.)
Frame rate 29.97
720 x 486
Color 24 Bits
Field handling interlaced field order B
Sampling rate 44
2 channels stereo
Do you recommend compressing the video coming out of Velocity?
There are a couple other options other than No Compression in the export dialogue such as: Microsoft H.263 video codec, Microsoft H.261 video codec. I definitely want to maintain the highest quality possible.
Frame Size: 720 x 486
Pixel Aspect Ratio: D1 / DV NTSC (0.9)
Fields: Lower field first
Display: Format 30fps Drop Frame Timecode
Audio: Sample 48,000 Hz
Display: Audio sample
Video Rendering: Maximum bit depth is Unchecked
Previews: File format Matrox uncompressed 8-bit NTSC (tried Matrox uncompressed 10-bit too.)
I think the jerky video might be due to dropping frames but Im not sure.
Any help is greatly appreciated!
While it seems that the field order is consistent, I have seen issues where converting from clips that change field order creates this sort of problem. This is particularly obvious when converting from MJPEG codecs like Meridien or Miro/Pinnacle to DV.
What happens if you just import the files into Premiere and let it do the rendering to the project settings?
