Re: "Same as source" FPS Improvements

I really did just save it to a file named patchfile.diff in with the rest of the SVN stuff.
Sorry. um, I know I'm supposed to know what I'm doing, if I'm in this thread, but I don't.

Yes chapter markers are on.

Re: "Same as source" FPS Improvements

I think this is relevant testing on my part, but let me know if not. I applied the new patch and tested with detlecine+vfr+b-frames on the same source as previous in this thread. The result is that the frames-out-of-order issue has moved further in by a few. before: http://img228.imageshack.us/img22...

Re: "Same as source" FPS Improvements

good results (smooth, in-order, not combed, a/v sync) for my test source (Sopranos season 6) without b-frames. Sorry I don't have exact details like you provided.

Yes, B-frames too please!

Re: "Same as source" FPS Improvements

Hi Van,

If I applied the patch correctly (which I'm not very sure about), it didn't work on this sample.
Any suggestions?

Re: "Same as source" FPS Improvements

you guys are right, with no b-frames, the area in question is smooth/sequential/non-combed.

Re: "Same as source" FPS Improvements

This may not be in the right spot and I know SVNs are not supported, but I think my observations may be useful. Using SVN r1227, I noticed some either missing frames or out-of-order frames depending on detelecine and vfr settings. Here is an example with normal preset (modified to crf 60) : http://i...

Re: Codec compatibility with Final Cut Pro ???

yes, .dv is a lossy codec, but not-very much relatively speaking (12GB/hour)
converting to a highly compressed codec like mpeg4 or h264 before editing is a bad idea in my opinion.

Try it, you'll see.

Re: Codec compatibility with Final Cut Pro ???

I would advise that you covert dvd-like sources to .dv for editing in FCP.
(mpeg streamclip is one app that can do it for you)

Re: Handle Occasional Interlaced Frames in Progressive Film

2. When using a de-interlace filter, HB has to apply the filter to each frame - this takes time - would it take more (or less) time (and by how much in relative terms) to examine each frame for combing. Then decide whether or not to de-interlace the frame? It'd take the same amount of time as pullu...

Re: Handle Occasional Interlaced Frames in Progressive Film

Two ideas I want to run past you jbrjake. 1. Is there a way to look for the "non-standard repeat flag pattern for soft telecining"? and examine those frames for coming? 2.

Re: Handle Occasional Interlaced Frames in Progressive Film

Thanks for your response.

I'll try an encode with de-telecine, or should it be detecine+vbr?

I've been keeping an eye on the "same as source" development thread, and while I won't pretend to understand the technicalities, I do see Van is doing some promising work!

Handle Occasional Interlaced Frames in Progressive Film

I've found that many feature-film DVDs have interlaced frames right at or near chapter beginnings. On a standalone player, one never sees those frames because a 2:3 pulldown is running the ntsc film rate movie at 29.97 fps. I've verified that the actual DVD is mastered this way by turning off de-int...

Re: Problem with picture quality...

I agree the problem is the fast de-interlace (and it's line dropping/doubling algorithm).
you shouldn't need to de-interlace these movies.

I wouldn't worry about the small amount of re-encoding. In a very simplified explanation, the video contains key frames (aka I-frames) that are entire frames. Other frames are rendered referencing the key frames. I think if you edit on a non-keyframe, new keyframes would need to be built on either s...

I'd say the iPod preset would still be a good choice. My iPod doesn't support video so I can't test.
I should also mention, if your edits aren't on I-frames, I think mpeg streamclip needs to encode a small amount.

You can edit an .mp4 (also known as .m4v) containing AAC audio using the program 'mpeg streamclip'. Do a 'save as' to save your trimmed file as an .mp4. This won't re-encode so its quick. You'll lose chapters though.

you should find a program that can convert ripped dvds to .dv format.
.dv is appropriate for editing, not handbrake mpeg4 based output.

mpeg streamclip would work.

DVDs are all anamorphic. For NTSC dvds, the frame is stored with dimentions 720x480. The frame is meant to be displayed squished or stretched horizontally. On a display with square pixels, this translates to 640x480 for 4:3 content or 853x480 for widescreen content. Extra widescreen films are still ...
