Glitchy Video Record with v2.2

Hiya

I'm trying to do a VJ mix which will be on a screen at an art exhibition.

my music track is 5m 22s, and I'm playing it off my mp3 player and triggering my first video simultaneously, recording the whole set from resolume, stopping record at the end of the audio track

my problem is that when I play the recorded video mix, its roughly 25% shorter than the audio track. I've tried 2 mixes and they both end up between 4m 15s & 4m 30s.

when I open the video files in Vegas, it tells me they are both 25fps. However the video mixes do not play in sync with the udio track. When I slow them down a bit, they do play in sync with the music track. Incidentally After Effects doesnt like the video files - when I open the files I get a message saying "After Effects error: retrieving frame from video stream (3) (53::34) "

I'm running on a PIV 2Ghz / 2 Gb Ram With an ATI Radeon 7500 gfx card, Win XP home. record in resolume is set to 25 fps. What codec does resolume use to record video?

does anyone have any thoughts? I think I'm gonna try upgrading to v 2.3 no2

thanks

> Have tried v2.3 but get the same problem. its simply playing back at a faster frame rate than it was recorded.

You are dropping frames and you probably always will unless you have bleeding edge fast processor and dedicated fast hard drive to record too.

Record your video and audio to DV cam then re-capture, search the forum w/ 'record' there's loads on this.

I did consider recording my S-Video output to DV CAM but seems so old fashioned considering the videos are being mixed inside the computer.

also, i won't gain any quality by doing this, as all my source clips are 320x240, but it will take more time.

since my first post I've done an edit in Vegas where I slow down the video clips (by a factor of 0.786 ) & edit betweena few mixes. It looks fine.

I originally searched the forum for 'record' but nothing came up so i thought the search was bust; the search works now but I can't find anything on topic, can you point me towards any topics dealing specifically with this problem?

thanks for the info. its a shame rez can't record without dropping frames

You won't 'gain any quality' however you do it. If slowing down the clip works for you, fine, but remember you've lost some frames that way.

It's not actually Resolume's fault, but your (and most peoples) hardware not being up to it - there's mainly just too much data being transferred for the drive to handle...

An avi recorded by resolume with uncompressed files at 320x240 has a data rate of 5-6 Mb

You could try capturing by video-in to a separate, reasonably fast, PC or DVD recorder too.

These threads deal with recording one way or another, mainly say the same thing but look through them for other options especially the last one.
