Batch 3:2 Pulldown Remover

[tthoms]

First, make sure the checkbox to remove temporary files is unchecked and run the conversion again. The resulting AVS file you show in your post is the "Clip 001-ANL.avs" file that is created first. After this AVS file is run during the analysis phase does the "Clip 001.ilc" file get created?"
.

Yes

"

and are there frame and metric entries in the file or is it empty?".

There are entries.

"Does a "Clip 001.avs" file get created and are there entries in it? ".

There are entries in this file as well.

"At a command prompt, go the the directory where the "Clip 001-ANL.avs" file was created and run this command:

X:\path to\ffmpeg.exe -i "Clip 001-ANL.avs" -an -f null null.avi

Replace the "X:\path to" with the path to your ffmpeg location. Ffmpeg should run and create the "Clip 001.ilc" file. If it doesn't, look for possible errors in ffmpeg's output. If that ran okay and created the .ilc file and a "Clip 001.avs" was previously created try running it using:

X:\path to\ffmpeg.exe -i "Clip 001.avs" -an -f null null.avi

Look for any errors in ffmpeg's. Let me know your results.

The ffmpeg run gave all sorts of weirdness:

First off it gives this=[null @ 037e95a0] Encoder did not produce proper pts, making some up.

Then streams of this for each frame= frame= 61 fps= 39 q=0.0 size= 0kB time=00:00:02.54 bitrate= 0.0kbits/s

Ending with= Clip 001.avs: Input/output error
frame= 2883 fps= 32 q=0.0 Lsize= 0kB time=00:02:00.24 bitrate= 0.0kbits/
s
video:180kB audio:0kB subtitle:0 global headers:0kB muxing overhead -100.000000%

Have I missed a step, or is my version of ffmpeg crap?

Thanks for your help!

I haven't seen a reply to my response, so I wanted to give this a one-time bump.

I'm not sure what those ffmpeg errors are. Have you tried using the Video for Windows compression option yet? First set the compression codec to use then run it. See if this works.

I've been successful (after a fashion) with this method. I saved the output using the lagarith codec, but strangely, the audio was out of sync. Can you recommend a different codec?

Yes, this is a problem with my utility. Because my utility converts the embedded audio in your source file to WAV format, saves it to disk, then optionally muxes it back into the new video file, sync sometimes isn't maintained. This has to do with possible audio delays built into your source file and when doing pulldown removal, some video frames at the beginning of the clip are removed. Your best bet would be to not mux the audio back into the video file but import the separate WAV files and video only file into your NLE and sync them on the timeline.

Way back I had a version that used Virtualdub to do the encoding and I'm thinking of going back to this since it would allow the utility to encode the video and audio at the same time thus minimizing any sync issues.

I thank you for your feedback, and your program!
