Oh no, not another video question!

'Fraid so...

I shot a video of a trio I'm in with a little Canon PowerShot camera that records AVI video. I also had access to the multi-track audio files from the sound company.

I loaded the video and audio into SAW, remixed, and rendered it to a DV Type 1 avi file. Everything went swimmingly until I tried to play it in WMP. It won't move... just sits there with the opening shot... I can move the cursor down the timeline and see all the video, but... no motion. It simply won't play.

So I then rendered it to a DV Type 2 avi file, and it plays back fine, but is out of sync. I think it gets worse the longer it plays.

Does anyone know a solution to this dilemma?

TIA

To start with - Make sure you have your MT set to the same rate your video is at *before* you begin production. Also... not a bad idea to also transfer the actual camera audio onto another track... and clap-sync it up (or whatever works for you). Then mute (or subtly add in) the audio from the camera.

Thanks Carl... I will do this and report back.

Carl,

The extracted audio from the video is at 44.1k/16bit, and the audio files from the sound company are at 48k/24bit. Which resolution and sample rate should I set in the MT?

Thanks...

I should mix the MT down to a stereo file 24bit/48khz. in a 24bit/48khz project.
than convert/save as/render this mix to 16bit/44.1khz (with a Dither).
start a new project, load the camera file and your mix.
now you can sync your mix to the camera file.
lower or mute the volume of the camera file to tast, mix this together to
a new stereo .wav file.
put this under the video and now it will be synced.
convert now the new video file to any format you like.

greetings

I have tried this, and the Type 1 render won't play, and the Type 2 render is still out of sync... getting worse later in the duration of the rendered video (about 40 minutes long).

All looks and plays great in SAWStudio; perfect sync all the way though... it's just the renders that either won't work or are out of sync. I MUST be doing something wrong; just can't figure it out. Thanks for your input Janneman.

I changed the MT resolution to 48k/24bit, and when I try to render to Type 1 I get a message saying "Trouble Building Render Graph". When I try to render to Type 2, I get a message saying "Bit resolution must be 16 bits".

So I mixed the audio tracks down to 44.1k 16bit and made a Type 1 video. Same problem that I had initially... it won't play in WMP. I can drag the cursor along the time line and see all the video, but I can't get it to play.

I'm stumped. Any suggestions welcomed.
