"Thank you very much! I always encode chapter points as I-frames. It's more reliable to jump to right chapter point."

Justin Sevakis replied to Justin Sevakis's discussion Encoding with ffmpeg
"Andreas, it looks like defining chapter points is not possible under ffmpeg. You'll have to do without, I'm afraid (though to be honest, I never bother with this even with x264)."

"Yes, I agree, if you're using AVIsynth for IVTC, there's no point to using ffmpeg."

Andreas Gumm replied to Justin Sevakis's discussion Encoding with ffmpeg
"Thanks. BTW, I let AVISynth do the reverse telecine process which works very well."

"480i/29.97 is now verified also... (Below is for 16x9 video, if you need 4x3 change sar=40/33 to sar=10/11, and also field order if necessary) ffmpeg -I input.file -c:v libx264 -pass 1 -b:v XXXXX -tune film -level 41 -g 30 -r 30000/1001 -flags…"

"Andreas, fakeinterlaced appears to work, but we're still testing for verification on those. I'll update in a week or so. However, it looks like ffmpeg doesn't pass -pulldown settings properly, so 480p/24 is out. I'm trying to…"

Andreas Gumm replied to Justin Sevakis's discussion Encoding with ffmpeg
"Sounds good! Is it possible anyhow to define a similar parameter to set "fakeinterlaced" for progressive content? How do you define chapter points? Is it possible to define a timecode list?"

"Great news! With a little work, I've managed to figure out the command line for HD video streams! Rob has been nice enough to run these through verifiers on his end, and we came out clean. This means that Windows users can encode with these…"

Justin Sevakis replied to Justin Sevakis's discussion Encoding with ffmpeg
"There are a few good reasons that ffmpeg would be preferable. x264 is very limited in how video is input; on Windows you have you use AVIsynth and a pipe like avs4x264mod to feed the encoder, and AVIsynth is still 32-bit. It can also introduce…"

Andreas Gumm replied to Justin Sevakis's discussion Encoding with ffmpeg
"Why using ffmpeg when you can use x264?Since no one has tested files created by ffmpeg in one of the known verifiers yet I don't trust ffmpeg in this task since the command line looks different and since it's still unknown what parameters…"

Encoding with ffmpeg

Hi guys,I'm wondering if anybody has successfully encoded .264 files with ffmpeg. Since it has x264 built-in, it should be capable of outputting Blu-ray compatible video. However, despite (I think) successfully converting all of the input parameters into ffmpeg's command line format, I'm getting compatibility problems on PS4, which leads me to believe that the resulting file isn't QUIIIITE up to spec. ffmpeg -I input.mov -c:v libx264 -pass 1 -b:v 30000k -tune film -level 41 -g 24 -r 24000/1001…See More

"I never had this problem on Windows 7 (I skipped 8) but definitely have it on Win10. I think a Microsoft Visual Basic security patch did it, so it must've started happening across the board.The only way around it for me has been to run DSA in…"

Encoding for Scenarist BD Slideshows

Here's a question for the general authoring public. I've been using the Slideshow feature on Scenarist BD. It's a feature that never really worked right on DSA, and I'm very happy to have it working now.One minor problem: the Still Image Encoder app provided with Scenarist just isn't very good compared to other encoders out there. Even at the highest bitrates some images are coming out with very visible compression artifacts.Has anyone used a 3rd party encoder (such as x264) to encode Slideshow…See More
