  1. Good evening to all you,
    I'm a newbie in video editing and I would post a question about a simple video conversion.
    I took a video with my Canon photo-camera, it was a MOV. So I converted it to MP4 in order to watch it on my TV set.

    I used Freemake Video Converter.

    The conversion was successful, but it flickers on the first frame.

    I tried more and more and changed many of the converter options.

    I achieved something good changing the video codec from H.264 (the converter default) to MPEG4.

    I don't understand if I have to discard H.264 or there is some other workaround.

    Is there somebody that can give me some hints?

    Sorry for my poor English. Here are some technical data:

    --- SOURCE FILE ---
    Quick Time Video
    size 58,8 MB
    19 seconds long
    1280 x 720
    29 frames/sec

    --- CONVERTED FILE ---
    MP4 Video
    size 8,24 MB
    19 seconds long
    1280 x 720
    29 frames/sec

    I also attach the (badly) converted video

    Thanks much

    Can you play the mov in for example VLC Media Player?

    I would try another free converter and see how it handles the mov like handbrake. Open the mov, select the universal preset, convert.

  3. Thanks for your answer Baldrick,
    OK, I'll install Handbrake to try a new conversion (I'll do that tomorrow )

    By the way, the original MOV file was correctly viewed in Windows Media Player.

    See you later, Baldrick

  4. Hello everyone,
    I have some news about my original thread. I discarded the Freemake converter and mounted the Video-to-video converter (free). Now the conversion works good and I can play the MP4 movies without frozen frames
    I first tryed convertion with these options:
    * MP4 Movie
    * Lenght: 19,886
    * Quality: custom
    * Video codec: mpeg4
    * Video size: original
    * Video aspect: auto
    * Video bitrate: 1024
    * Video framerate: auto
    * Audio codec: aac
    * Audio bitrate: 128
    * Audio sample rate: 44100
    * Audio channels: 2 stereo
    * Sync A/V: no
    * Audio stream index: default
    * Volume: 1/8
    * Target filesize: unlimited
    * Two pass encoding: no
    * Deinterlace: no
    * Keep aspect: yes
    And then I got a 2,86 MB file
    Changing the Quality option to "Same as source" I got a 53,7 MB file
    Changing the Quality option to "Lowest" (which also moves the Video and Audio bitrates to 1732 and 64, respectively), I got a 4,37 MB file
    And finally, changing the Quality option to "Highest" (which also changes the Video bitrate to 10400), I got a 25,0 MB file

    Well, I'm absolutely a newbie in video processing, so I've a poor comprehension about those options. Playing the converted files, I discarded the "lowest" and the "custom" files: artifacts are too much noticeable.
    But I found it difficult noticing any differences between the "highest" and the "same as source" files. And between these and the original MOV file. By the way there is a very big difference between file sizes:
    "highest" is a 25 MB file
    "same as source" is a 54 MB file
    the original movie is a 59 MB file
    I would ask you if there are some tips which can help me in choosing the "quality" option in this conversion (and in the future ones, also).
    Furthermore, are there some options (other than the "quality" one) I can/have to change, to get good MOV to MP4 conversions?
    Thanks everybody for your care

    Now I append some other technical info about the original MOV file:
