    MP4 and AVI are usually good quality. However it mainly depends on what the two files were encoded with.

    While your question doesn't exactly make sense, I believe the answer you're looking for is XviD. Avi is a container and mpeg4 is divx/xvid. Mpeg is an older format that's somewhat obsolete considering the file size/quality ratio is awful.

    x264 is the best quality encoder and mkv is the best container.

    ...........ok still I want to know the best quality format regardless of size.

    I take game videos with fraps and it is "video file" format and it is huge file..... like for 30sec vido it is about 300mb and I cannot straight up upload it to youtube it says it the file is not valid so I had to convert it tpo other format first before uploading to youtube but anyway forget about youtube... pretend youtunbe have nothing to do with it.

    Pretend I still want to convert it to the best looking image quality despite of youtube... will not upload to youtube.... but just want to convert it to the most best quality and just for making the size smaller....... which format is the best quality?

    As I see..... mpeg1 is noticible superior quality than mpeg2...... why is that? I thought the higher number the better quality?

    Which format is the best quality?

    x264 will give you the best quality and mpeg1 is not better than mpeg2

    I convert two of my videos.... one with mpeg1 and the other with mpeg2..... I play both at the same time and compare..... the mpeg2 looks brighter (too bright) and the mpeg1 is sharper and deep brilliant color. just as I see/experience.

    thanks for the link

    edit: ummmmmmmmm ur right..... i got mix up.... mpeg2 is the one with sharper and deep brilliant color.

    ok, it's all about quality to file size ratio on this... here's a list of codecs and their relative sizes for the same quality and picture size...

    example:
    640x480 video at 29.97 fps with total length of 24 minutes and no artifacting.
    xvid - it's about 180 mb.
    AVI - this is a file type container, so it would be safe to ignore this.
    X264 - around 140mb to 150mb
    mpeg4 - it's a general class, look into h264 or x264.

    Personally i'd go with X264 or h264, and use mediacoder to encode the videos.

    note:

    to get the best file size and quality ratios it's trail and error, however once you get it down you'll find very few issues, i've got good results on h264 using around 700 to 800 kb/s rates.
    HiddenStupid says thanks.

    wow that program looks nice. it says:

    "MediaCoder is a free universal batch media transcoder"

    is that mean its fully free?

    nice program - any advice o how to get my files to a set size? want to get them 700MB to fit on CD, instead of random sizes...

    edit: i found a setting under "mode" which allows me to set a filesize, but as teh DVD movies come with 4 main IFO files they EACH get set to 700MB. is there an easier way, or should i do this and join them somehow, then re-encode them to 700MB again? I just dont like the idea of encoding it so many times.

    it's your personal preference, because repeated encodes are key to getting things working right... you should be able to encode a 2 hour long movie down to a single 800mb file with x824... anyways the trail and error bit is mainly so you learn the options, because i personally don't want blocks in the video playback i do.

    so...... x264 is the best quality.......

    what about between mpeg2 and mpeg4? which is higher quality?

    Yet again, this depends on the encoder settings...
    mpeg4 looks a whole lot better on lower bit rates ( around 750 kb/s for a 640x480 video. )
    mpeg2 looks the best when on higher bit rates ( your looking at 1.5 to 4.8 mb/s for 640x480 video. )

    Thats such a bad question. Mpeg2 is better quality because it isnt compresed like mpeg4 is. However, if say you want to limit a file to 350MB, mpeg4 would be better because it is better compressed.

    Very true in most respects, but mpeg2 is the codec that is used in dvd players because it has less hardware requirements on processing power.


    use h264, because x264 is based on that.

    Settings could of caused the crash, try using the stock settings, with the only changes under the video tab being full pixel motion to exhaustive, the bitrate from 750 to 800 kb/s and if the video quality is not very good set the mode from bitrate based to either 2 pass or 3 pass. ( source and backend should be set to auto select for best results on video)

    as for audio settings i would use vorbis at 500 ( or 0.5 depending on the encoder)

    ending with the muxer/container, pretty much i leave this stock and use the mkv container for the most part.
