What do you suggest ?

Hello.

We show 1- 5 min video clips a week. We edit in Vegas video and show them through a projection system. We have been using a dvd player that supports non finalizing discs and buring mpeg files to a cd-r and showing the video

the problem is is that now the videos are playing back choppy during heavy action parts. this ( i found out after much resaearch) has to do witht he bitrate. The problem is i do not know what bitrate to render the mpegs out at.

I tried to lower the rate but tthe video is too pixelated.... does anyone know what the bitrate should be set at. the video is 720 x 480.

We may start bruing dvds but for now this method is so fast and easy... i just wish it would work better.

For DVD MPEG2 format I would not go less then 4000kbs. The more the better for heavy action. I usaully capture/edit/render all my video at 9000Kbs. Since my videos are all mostly less then 1hour I can fit them to a single DVD.

Also check the interlace and field order settings if they appear choppy through out the whole video.

Since they're just short clips, crank it to the max 8,000 kb/s. You can never have too much.

buring mpeg files to a cd-r

You say these are on "CD" so are they mpeg1 vcd, mpeg2 svcd or mini DVD or just mpeg1 or 2 but not in a vcd or svcd structure (root play with PBC off)? If they are mini DVD and supported by your player then you can crank up the bitrate a bit but the cd laser will have trouble if it's too high. If not a mini DVD then there are max values for vcd and svcd bitrates that would cause problems if you go too high. I haven't burnt any in a while but it should be easy to check. My recollection is about 2600 for svcd max and about 1150 for vcd. Anything above that creates non standard cd discs that may cause playing problems. Also make sure that the audio is 44K and not 48 on cd. Although many players accept this, I believe, that your resolution (720x480) is out of spec for vcd and svcd but ok for mini dvd.

Check the Video setting table at the bottom of this page https://www.videohelp.com/dvd for approximate max values.
