Splicing in frames with VirtualDub and AviSynth

[theseeker2]

I'm trying to replace 18 bad frames in a HuffYUV AVI file which is captured VHS footage. I have clean frames in another HuffYUV AVI file, so I saved an image sequence as BMP files from that AVI. I've already stripped the audio out of the AVI file so I'm just working with video here.

I thought this would be easy using an AviSynth script, but I keep getting this error:

Avisynth open failure:
ImageReader: EBMP reader cannot handle compressed images.
(C:\temp\vdubscript.avs, line 2)

I'm guessing this is due to my BMP files being from a HuffYUV file. Surely AviSynth can read HuffYUV files?

For reference, here's my script:

A=AVISource("I:\Jars Box\temp.avi",False).ConvertToYUY2().AssumeFPS(29. 9700)
B1=ImageSource("C:\temp\frames0000.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B2=ImageSource("C:\temp\frames0001.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B3=ImageSource("C:\temp\frames0002.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B4=ImageSource("C:\temp\frames0003.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B5=ImageSource("C:\temp\frames0004.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B6=ImageSource("C:\temp\frames0005.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B7=ImageSource("C:\temp\frames0006.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B8=ImageSource("C:\temp\frames0007.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B9=ImageSource("C:\temp\frames0008.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B10=ImageSource("C:\temp\frames0009.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B11=ImageSource("C:\temp\frames0010.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B12=ImageSource("C:\temp\frames0011.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B13=ImageSource("C:\temp\frames0012.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B14=ImageSource("C:\temp\frames0013.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B15=ImageSource("C:\temp\frames0014.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B16=ImageSource("C:\temp\frames0015.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B17=ImageSource("C:\temp\frames0016.bmp",fps = 29.9700,End=0).ConvertToYUY2()
B18=ImageSource("C:\temp\frames0017.bmp",fps = 29.9700,End=0).ConvertToYUY2()
C=A.Trim(0,4037)
D=A.Trim(4055,0)
C+B1+B2+b3+b4+b5+b6+b7+b8+b9+b10+b11+b12+b13+b14+b 15+b16+b17+b18+D

My guess would be you didn't save the bmp's correctly. Can you open them in an image viewer ?

But there is no reason to use images in your case, you can use 2 huffyuv files in AVI

You can trim the frame range of the 2nd huffyuv file in the script if you needed to . If it was the same frames as "A" , then add .Trim(4038,4054) to the 2nd line

A=AVISource("I:\Jars Box\temp.avi",False).ConvertToYUY2().AssumeFPS(29.9700)
B=AVISource("otherhuffyfile.avi", false).ConvertToYUY2().AssumeFPS(29.9700)
A.Trim(0,4037) ++ B ++ A.Trim(4055,0)

Thanks for the ideas pdr. I ended up recapturing the source footage and after playing through the tape a few times was able to get it without the glitches.
