motion jpeg to xvid?(virtualdub) & getting motion jpeg into gordian kno

[skidog]

Q1:i'm having trouble using virtual dub to save my canon digital camera video's to xvid, Virtualdub keeps making them 733kbps by default when i'm putting in 1000 for the target biterate, i tried making a new stats file and still no dice.

I can get divx and h.264 to give me my target bitrates no problem i'm just having trouble with xvid, using 1.03. Xvid does work fine in gordian knot though.

Q2: Also what format do i convert motion jpeg to(using virtual dub), so that guardion knot, and tmpeg will open it for encoding? I think i've tried uncompressed RGB (WOW BIG), and intel IYUV, both in .avi container but no dice, gordian knot just give's me an error when i press "encode"

raw canon digital camera file stats:
Size: various
Container: .AVI v1.0
Video Codec: mjpg (Motion JPEG)
Quality: ~12000kbps
Video Resolution: 640x480 30.000 fps
Audio Codec: PCM 11khz 88kb/s mono

tmpgenc should be able to open it if you can play it with wmp. you might need a decoder for mjpg like ffdshow.

For VD output to a MPEG encoder, try HuffyUV, or for a little smaller filesize, DV with a codec like the Panasonic DV Codec. Since you are using VD and TMPGEnc, you might look into frameserving the output directly to TMPGEnc encoder. It's easy enough and saves you from having to make an intermediate file from the VD output. One guide: https://www.videohelp.com/virtualdubframeserve.htm

Usually GKnot opens D2Vs, but it should also open AVIs and AviSynth script files. I assume you've already tried to open the MJPEG directly with no luck, so make an .avs out of it:

AVISource("C:\Path\To\Video.avi")

And if that doesn't work, DirectShowSource should do the job:

DirectShowSource("C:\Path\To\Video.avi")

Or if the extension is .mjpeg (I have never worked with them), use that instead. Always test your scripts in VDub(Mod) before encoding so you'll get a real error message if something's wrong. I assume you've installed whatever codec you need to play this thing on the computer. Baldrick covered that base already.

I think i've tried uncompressed RGB

If you want to open an AVI directly (shouldn't have to, though), then don't use VDub's uncompressed, but use a lossless codec, such as Lagarith or HuffYUV. Much smaller.

using huffyuv 1.3.1 will let me open the video in gknot, but when i go to encode i get:

avisynth open failure:
UnDot: Supports YUY2 color format only
c:\**********\*.avs, line 54

my huffyuv video is also 830mb per minute, and i didn't check any options in the config for it.

You encoded in RGB (mistake). Do one of 3 things; edit the .avs to remove the Undot() line, go back and do a HuffYUV encode in the YUY2 colorspace, or go back and convert to a Lagarith AVI in the YV12 colorspace. I always use Lagarith. Although it's going to make for slightly slower encoding, it's also going to give you smaller file sizes (if you use YV12), and be in the final colorspace already (YV12). Typically, Lagarith in YV12 gives me 18 GB or so per hour of video at 720x480.
