  1. I dont know if this has been seen before but im trying to encode a dv file to an .avi file. Doesnt matter which XviD, mpeg4, or divx 3. Anyways when i do it to mpeg1 or vcd mpeg1 it works fine and encodes the whole file but when i choose one of the .avi settings it only encodes about 9-10 minutes of the total 22 min file. It acts like its finished and everything but when i open the file to watch low and behold its only about half there. Thanks.

  2. Oh well, I guess nobody knows. At least i have the vcd.

  3. Have you tried with the "fast DivX" preset?

  4. No come to think of it i forgot that but ill give it a try, dont have the file with me so ill have to wait until the weekend and ill report back

  5. I have the same kind of problem with .dv material, but they are a little bit different;
    I use a A/D-converter (Formac Studio) and record it with iMovie, cut the commercials out and export it as a medium quality 720*576 PAL DV stream with 48 kHz to an external Lacie d2 FireWire-harddrive; it is then one .dv file with 15-20 GB; then I try to encode it in ffmpegX 0.0.9a to an .avi.
    The settings are as following: mp3 audio with 192 kBits VBR, recorded as one 1,2 GB avi file with 2000 kBits video bitrate, and cropping as following: 704 434 8 70; in the video settings I take as video parameters 704*434, Unknown and PAL 25 images/sec frequency.

    When I use the ffmpeg codec, it starts encoding and i get the following message: <dimensions are out of range, remember to scale first and then crop second>; i use the deinterlace filter with two-pass, high quality, B-Frames and and 4 motion vectors.

    When I use the mencoder codec, it starts encoding and stops after 9min 55 sec of the movie processed without any warnings; I use all filters available and two-pass with all other options activated.

    I still can encode it with ffmpeg without cropping, but I would like to take advantages of the better filters of mencoder, so if someone could give me an advice, I would be very, very happy to really start using my Mac the real way.

    The ffmpeg codec uses for now different crop values. They must be entered in TBLR (top, bottom, left, right) format, so you need to calculate this manually for now (this will be automatic in later versions). The mencoder crop values are not in TBLR format but width-height-x,y origin.

  7. Thanks for the quick help, major, but it creates another problem:
    when I Use a 720*576 DV file, and want to cut the black bars, I use 704*336 with 120 120 8 8 and I get a 4:3 avi file with eggheads using ffmpeg; when I use mencoder with 704 436 8 120, i get the scaling/cropping that I want, but it stops encoding after 9 min 55 sec.
    Am I doing something wrong with the ffmpeg cropping , or is there another problem??

    i have tried the same thing and have the same 4:3 output.

    need to encode to 528x224 from 704:320:8:128 mpeg2 file with separate audio file.

    thanks for help

    update: when i cancel the encoding process and open the .avi made using the ffmpeg encoder in quicktime it shows the correct size of 528x224. vlc and mplayer show the same video in 4:3 ratio...

    maybe this is of help

  10. It is very important, that you do NOT choose the "Full Quality DV" Setting when exporting from iMovie. This just makes iMovie glueing the 2GB chunks together in which it records movies. Mencoder can't handle that.
    Here's what to do:

    Choose "Expert settings". Click "Export". Choose "Movie to Quicktime Movie". Click "Options". In "Video Settings" choose "DV PAL" (or NTSC, if you are on that TV System).
    In the Audio settings, choose uncompressed 48khz Stereo. Uncheck "Prepare for Internet streaming". Make sure the output file has .mov as extender.
    Now the recording is reencoded as a single movie which Mencoder will encode completely as AVI.
