The above is called "anamorphic encoding". They should look fine when played using a PC/software player though.
Aspect ratios in AVIs are almost never supported. Unfortunately though, aspect ratios in MP4/MKV files aren't universally supported by hardware players so the video mightn't display correctly. The video is resized to the correct aspect ratio on playback (either 16:9 or 4:3) but the resolution is always 720x480.įorgetting any cropping of black bars for the moment, you can encode the video "as-is" (720x480) and the output MP4/MKV should be resized on playback to the correct aspect ratio the same way the original video would be. The mpeg2 video you referred to doesn't use square pixels. MeGUI can edit, but it has more of a learning curve than other encoder GUIs and setting up an encode (if you do everything "manually") can take longer.Ī few tips when re-encoding DVD/mpeg2 files. As you said though, you can't edit with it (although it will let you specify a start and end point for encoding). Handbrake is probably one of the easiest to use programs to give you more control over other aspects of encoding (resizing/cropping/de-interlacing etc), although generally it'll do a good job without much user knowledge required. Better to waste bits than not use enough. If you can't use a quality based encoding mode it's probably an idea to be generous with the bitrate. It's possible (although far less likely using the x264 encoder than Xvid) that a noisy, low quality video will require as much bitrate as the original to compress to a decent quality. The required bitrate for a given quality is determined by how hard the video is to compress. It has no idea what birate might have been used originally. The encoder only sees uncompressed video which it then re-compresses.

Video To Video Converter doesn't, and I'm pretty sure AnyVideoConverter and Super are the same.Īlso, will a 12,000 bit MPEG-2 file converted to 1000 bit MP4 have the same quality as a 5000 bit MPEG-2 converted to the same 1000 bit MP4? There's zero relationship between the bitrate of the source file and the bitrate required when re-encoding it. I'm not sure why most of those "one click" conversion type programs don't have an option for CRF encoding. Is the h264 encoder setup any different? Admittedly I could only find a pic of it's encoder setup when using the Divx encoder. There's no option to choose anything other than bitrate I can see. I don't have Format Factory installed but I found a pic of it's encoding setup. The bitrate can vary quite a bit from video to video, but for a given CRF value the quality relative to the original should always be pretty much the same. Instead of taking a guess at the bitrate required and hoping for the best, you pick the quality (it's called a CRF value) and the appropriate bitrate will be used when encoding. That's why x264 has a quality-based encoding mode. While it's true bitrate relates to quality, no two videos will compress to the same quality using the same bitrate. I'm only guessing, but your first post implied Format Factory's "quality" is based on bitrate (as you only mentioned bitrate yourself). You would have to extract the timecodes and examine it to be sure."Quality templates" and quality based encoding mightn't be the same thing. Because it looks like it's minimally variable if you assume mediainfo is correct. What lansing is probably suggesting by "false alarm", is that there is a small chance you can just assume a CFR framerate by overwriting timecodes, e.g. If it's in sync there (assuming you can playback UHD in realtime), then it's almost 100% guarenteed to work if you encode an intermediate first before editing / other filters In fact, you can just check it really quickly in MPCHC, jump around a bit. But this assumes your directshow system is configured correctly. The other methods are slightly less accurate and can have slight problems with frame placement. It's still the right answer and source filter if you want to edit and use avisynth. Xvid4psp converts it to 23.976 but i don't think that the new versions use AviSynth so there's no script to inspect.
