I've reported the issue on Debian bug tracker here, as well as upstream here. Really the only available reference implementation can be found here.
It's never a bad idea to have resolution and bit depth to spare during post but if you don't need the extras -- higher bit depth for cleaner effects / color grading, higher res for crop and blowup and so on -- then you can reduce the originals to the final output values with no loss of fidelity.
I had this issue for a very long time in pretty much every program I played MP4 videos in. It turns out that by default, the Nvidia drivers don't actually have the full dynamic range enabled. I changed it, and tested it just to confirm that it really worked. Just open up the control panel, and change the dynamic range to "Full": Regarding the current ...
They came in as .ogg?? I thought you converted to dvd? Are you talking about then ripping the DVD video with HandBrake or something? Also, you're doing something wrong, or at least have your file extension -> "open with" settings screwed up if renaming a .ogg to a .mp4 is necessary. Maybe it opens with a different player then, and only the player ...
One big loss in converting VHS to DVD arises from going through the composite domain. Both VHS and MPEG2 use a separated chroma paradigm -- on the VHS tape are two signals, essentially luma and bandwidth-limited chroma. MPEG2 (the standard for DVD) also uses separate luma and chroma. But the standard output from a VHS player combines the signals in a way ...
The best way to conserve the VHS's would be to scan each frame in at the highest quality possible and export to a video file, this would be a very long process and would require some expensive kit or a professional service. If they are historical value and you want the best it would be worth spending the money and getting it done by a pro but that cost is ...
After some research, I discover this post. So far the API for http://www.omdbapi.com has proven to be exactly what I wanted. For completeness, I found those command line tools helpful: https://github.com/xbgmsharp/allocine https://github.com/bgr/imdb-cli And on debian: $ sudo apt-get install python-imdbp
LordNeckbeard explained in his answer, why the given ffmpeg command line does not provide any known advantage. But what - in general - could be reasons to transcode? Available input codecs/containers of your NLE (video editing software) There are hundreds of codec/container combinations out there, and maybe your NLE has just problems with the one that ...
On this page author reencodes MP4 from GoPro to MOV for "easy post processing". Why the processing becomes easier after that? The author provides no explanation and does not go into any detail of what he means by "post processing". What we know: The author's ffmpeg command is using the encoder mpeg4 which will output MPEG-4 Part 2 video (like the old ...
