I'm having a rough time getting a codec to take that I can then "print to tape" using another program.
I'm running the subtitler filter over an avi.
Virtual Dub seems to want some compression applied, an uncompressed "save avi" is huge.
Do i need another DV codec?
my avi (about 8 gig) goes into virtual dub great, but comes back "choppy" when I try and make it about the same size as it went in.
If I compress it down to a mpeg, it seems ok, just the loss of quality.
what codec does Adobe use for its standard avi straight out of premeir?
When I look at the properties of the file, it just says dv codec.

Vdubs subtitle filter will 'burn' subs into the video one and for all time, and this requires reencoding the movie completely.
What exatly are you trying to do ?

I have a avi that was edited together in Premeir (microsoft dv codec), I want to use virtual dub to add subtitles (this part works) and then print to tape without losing any quality.
Premier doesn't like any of the dv codecs I have. When I print to tape, the become choppy.
I'm not stuck on using premeir to print to tape.
I guess I'm just struggling with a codec compatibility issue. |

Hi rodeo
i just saw your second post. It is not a good idea to split one topic in several posts, because readers easily overlook details.
No, AP is probably not the reason why the video gets choppy, when you "print to tape". And AP can work with Microsoft DV codec. Producing choppy video with VD export is another topic, see below...
Choppy "Print to tape" is faulty DV video transfer.
First check the transfer of DV material from camera to PC and back from PC to camera. It is essential that this works without producing choppy video.
Start with the software tools which you got with your PC, because they may be optimized for its hardware. APs DV transfer depends on proper installation of the DV subsystem of your OS and AP compatible firewire hardware (iLink hardware) and may fail with your PCs hardware.
Optimize your PCs hardware and OS. Choppy DV video transfer is often a result of shared interrupts of the firewire card, interference of firewire card with graphic card (don't put both cards in slots next to each other), unnessessary background software in OS (switch off virus scanners, screen savers, internet file transfer software, task schedulers...) and unsufficient harddisk performance (enable UDMA mode for HDs; defragmentation of the harddisk is good too).
Sometimes DV transfer software works with DV AVI type-1 files only. I think Sony DV Gate Motion is compatible with DV AVI type-2 files. In other case you can use a DV file converter to convert the DV AVI type-2 files from AP or VD (VD with VFW DV codec) into DV AVI type-1 files and vice versa.
Choppy video export from VD
Choppy video or a degradation of video quality? Degradation depends on the selected codec and codec parameters. Use a VFW DV codec and you will get a 8 GB DV AVI file or select HuffyUV and you will get several AVI files with a sum of approx. 22 GB. Both methods can produce video without visible degradation. But you'll need AP to render the HuffyUV AVI files in a 8 GB DV AVI file again, see my other reply.
Bye
Stefan
