    Aspect ration lost during convertion.

    I have an anamorphic source file with an aspect ratio of 16:9.
    Once converted, it is now close to 4:3.

    The encode is for a mp4(h265).

    Here is the convert log:
    Code:

    Out of interest, who created that source? It's completely screwed up!

    It's been encoded with a 718x480 (mod-2 block size) resolution and variable frame rate!

      Variable framerate is very common with science-fiction TV Series DVD.
      Star Trek, Stargate are confirmed are like that for example.

      Typically, filmed scenes are done in 23.997 fps progressive and special effects shots (like the generic) are 29.997 fps interlaced.

      To keep everything, you need the variable framerate. That is why the Handbrake tool is set by default at variable framerate according to the manual.

      Furthermore, to avoid deinterlacing visual artefacts, it can be a real headache of selecting the right mix of detelicine and deinterlace algorithm. I remember the Stargate SG-1 content being real nasty to do with a double encode. The first pass with detelecine and the second with Handbrake's "slow deinterlace".

      As for the mod-2 block size, it is Handbrake's "strict anamorphic" setting that made the call. I found that setting to be the less troublesome one for compatibility among my players.

      I have yet to see that with bluray sources. Most likely, it is no longer permitted in the format.

      By the way, 9.1.7.7 handled those files just fine.

        Nah... Only if the files you've downloaded have been encoded by an idiot, who has no idea what they're doing!

        By-the-way: I've been working with digital video at a professional level for over twenty years...

          By the way, I AM the person who encoded those files (in case it was not clear enough in my previous posting).

          Anything mentioned above, I can demonstrate.

          You need to get you facts straight. Any search on the format used by Star Trek DVDs will yield results on the subject. That pretty easy to confirm by monitoring the effective framerate upon playback of the source media.
          Granted my use of "common" can be debated, let's just say that it is common enough in my TV series DVD collection (over 6 series out of 9 with it to varying degrees).

          Nah... Only if the files you've downloaded have been encoded by an idiot, who has no idea what they're doing!
          By the way, that last comment can be seen as a serious lack of professionalism on two accounts.
          1- Name calling someone without verifying your facts.
          2- Accusing someone of illegal activity without a shred of evidence.

          Also, in computer engineering research, profession naming doesn't hold a shred of weight. What matters is what you can demonstrate.

            There's no facts to get straight here. If you originally generated those Stargate episodes using Handbrake, you should have selected the 'constant frame rate' option and not resized to 718 pixels!

            Sufficed to say, no commercially produced DVD, Blu-ray disc, TV broadcast or camcorder captures video using variable frame rates!

            Just because some encoding application offers you some wacky encoding options, does not mean you have to or should use them!

            Oh... By-the-way. The 'convert log' you provided clearly states the word 'downloads'!

              Before bashing on a feature you should learn about it.

              The "Variable Framerate" feature is not generating variable framerate in the output for some dubious advantage.
              It is a "if the source is variable framerate to begin with, leave it as is" feature.


              I am well aware that accepted best practice is to use modulus 16 size to allow the best alignment with the internal macroblock sizes. Yet modulus 2 is still within the standard. At time, handbrake's modulus 16 option failed with microsoft Video app, which was part of the players to support. Whose bug that was did not matter. The "strict" option worked everywhere consistently (including with DVDFab up to 9.1.7.7 inclusively) and provided better vertical upscalability.
