    Hi,I'm a frequent user of 3 trans-coding programs :


    My first issue is Using Media-coder :
    I have a problem with some files, they seem to not convert if over 2 gigs in size. i like to convert my files from mkv to mp4.
    I cant seem to get the right output file , the conversion output says even though it went through the trans-coding process
    there is no output data but there is input data
    i have everything set to my parameters and it does everything but it comes up as a blank mp4.


    Here is my error :
    http://ss2web.com/IQccVm2y8


    I use these setups for my trans-codes :


    I use this set up for Video :http://ss2web.com/I85n8IPx3


    I use this set up for audio :http://ss2web.com/INBkpULNa






    I also tried FFmpeg , i set it up correctly, put my file in the directory, i get this error pictured below and i need help with correcting it.

    Also with handbrake it does the same thing with these 1080p 10-bit 5.1 Flac mkvs, I set all my parameters to the way I like them,i start the trans-code and the time spent encoding just goes up, no progress is made. It stays at 0%. Even with other file types like mp4, it works fine but recently it hasn't been working.


    All these programs are up to date
    If anyone could give me any recommendations for Trans-coding software,


    I mostly have 1080p and 720p 10-bit mkv files with 5.1 Flac audio, i'm really stuck here

  3. FLAC is not supported in MP4 container . I think you might be able to convert it to ALAC (Apple Lossless Codec) if you wanted to keep lossless audio in MP4

    Thank you , I will try alac, is it similar to flac? Lossless quality wise? Or is there anything better like ac3 or aac?Thank you for your inputs

    Is there any plugins for handbrake for alac? Or any programs that will support it?

    "C:\ffmpeg\bin\ffmpeg.exe" i "c:\ffmpeg\Ghost .mkv" -c:v copy -c:a copy "c:\ffmpeg\Ghost.mp4"

    You have to use full paths and quotes if there's spaces.
    It's a good idea to always use quotes for paths even with no spaces.

    FFmpeg also has an alac encoder, however mp4 doesn't support alac either, so you have to use the quicktime mov format.

    "C:\ffmpeg\bin\ffmpeg.exe" i "c:\ffmpeg\Ghost .mkv" -c:v copy -c:a alac "c:\ffmpeg\Ghost.mov"

    Alac is lossless similar to Flac, AC3 and AAC are lossy similar to mp3.

    FFmpeg doesn't have a good built in AAC encoder.
    The only reasonable choice for mp4 with FFmpeg is to use AC3 for 5.1 audio.

    "C:\ffmpeg\bin\ffmpeg.exe" i "c:\ffmpeg\Ghost .mkv" -c:v copy -c:a ac3 -b:a 448k "c:\ffmpeg\Ghost.mp4"

    Why do you convert to mp4 ?

    I used mkvmerge GUI, I replaced the AAC with the Flac audio, it pre parsed the flac file into the mkv file .


    So it shouldn't be saying no stream when there obviously is .

  7. It should be "-i" without the quotes ; he's missing the "-"

    Code:
    "C:\ffmpeg\bin\ffmpeg.exe" -i "c:\ffmpeg\Ghost .mkv" -c:v copy -c:a ac3 -b:a 448k "c:\ffmpeg\Ghost.mp4"
    ALAC works in .m4v or did you need .mp4 container

    I Choose mp4 because i use it on my array of devices, my tablet and ps3 and phone
    i dont like mkv for mobile or tablets, it tends to lag at high quality video so i opt to convert to mp4.

    Oh, is there a way to have the bit rate higher? the flac file was around 3500k. and will it be in 5.1 channel with the highest bit rate possible?
    Thank you !!!
    It is starting the process.
    Now , do i do this for every file?
    and how will i know when it is half or fully done?

  10. You can batch encode if you want with ffmpeg e.g. process all the files in a directory . But I don't think there is a progress indicator or estimator with ffmpeg . Some ffmpeg GUI's might have a ETA

    what is a good bit rate for ac3? if the flac file was around 3500k 5.1there are no subtitles in the finished product, and is there a way to put it at 8bit mp4 with the same file? like convert it with the ac3 instead of the 10bit hi 5?
