H.264 Interlaced Question

@Tom Wolsky: I didn't want to stray OT on the FCP X thread where the OP is mixing SD and HD interlaced.
Just to say that I have never found a setting in Compressor that will allow me to output interlace H.284 – even from interlaced source material. Not that I'd ever use it myself, but if there are settings that will do just that, please let me know.
Thanks.
Russ

Thanks, Tom. Undoubtedly that works, although don;t have any interlaced H.264 to use as a source file. But an interlaced XDCAM clip flipped to progressive when I chose MPEG 4 as output.

Adobe Media Encoder de-interlace question

My video in the preview displays horribly interlaced, this is odd because the footage in the timeline displays correctly and clearly as well as my original footage. What seems to be the problem, I've tried rendering with de-interlace as well, it still shows fairly bad after being rendered.
All my original footage is 1280x720, 25fps.
My settings:
Format: H.264
Range: Entire Sequence
NTSC, 1280x720, 25[fps], Progressive
AAC, 160 [kbps], 48 kHz, Stereo
VBR, 2 Pass, Target 8.00, Max 8.00 [Mbps]
Video Codec: MainConcept H.264 Video

Rendering an uncompressed video yeilds the same results as Media Encoder.

On further inspection, Even still renders are interlaced like mad...
What's wrong?!
EDIT:
I fixed it!!! Apparently when speeding up or slowing down clips, it merges the frames together giving off that horrible look! So I turned off "frame blend" And it looks super awesome.

How to export h.264 interlaced video??

hi, my situation is the following: i have a full hd (1920x1080i50) camcorder which gives me just interlaced video clips with 50 half frames per second in AVCHD. i dont want to deinterlace the material, cause it taks too much time, the quality looses and the filesize is doubled (if i want to keep every frame).
i want to cut it with imovie 08 and then export it back into h.264 in interlaced format. (because i want to burn it to a data-dvd and play it in a playstation3. and h.264 is the only full hd format, which the ps3 is able to play, i think).
but in the export preferences i cannot choose between the options "interlaced" or "progressive". and the export with quicktime as h.264 or mpeg-4 is always in progressive mode, ignoring the interlaced material. the result is a progressive video with 25 full frames per second showing 2 half frames mixed together in one frame with the typical "interlaced-lines-error" or in germany we are talking about the "picket-fence-effect". it seemes that imovie does not identyfy the interlaced video automatically.
the imported videos from the camera are definately imported by imovie as interlaced video. i can check it in the quicktime player by turning on the "deinterlace"-option. quicktime playes the video deinterlaced, the "picket-fence-effect" dissapears. if i do it with a exported h.264 videofile from imovie, nothing happens when i turn the "deinterlace"-option on. the "picket-fence-effect" does not dissapear.
today i already loaded the quicktime update, but i still can not export in mpeg4/h264 interlace.
can somebody help me?? i spent already several days with exporting, searching the internet and burning dvd-rs.
thanks

You should give MPEG Streamclip a try:
http://www.squared5.com/svideo/mpeg-streamclip-mac.html
In this program, interlace/deinterlace is an option for MPEG-4 conversions, although I haven't used it myself.

H.264 encoder question

For my streaming application I need H.264 video content with sliced frames and H.264 slice size should be configurable. I tried QT Pro and found that it partitions a frame into 2 halves. Is it possible to configure the encoder to produce more slices?

You answered my question in #2. I am not sure I understand how services such as ustream.TV can webcast in H.264/MP4? Since smartphones can send the stream only in FLV/H.263; Do they re-encode the livestreams from H.263 -> H.264 at the server using FlashMediaEncoder?
Another question: lets say if I can somehow encode the video myself (H.264) at client side in realtime; can I publish it to FMS as MP4/H.264?
Thanks!

H.264 Encoding Questions...???

I am now starting to convert different video files to my iTunes for my AppleTV and have some questions...
BTW, I am using VisualHub and using H.264 - high quality setting for encoding on a G5 iMac with 1GB RAM.
1. Approx. how long should it take to encode a 700MB .avi file to .mp4, using H.264?
I am transferring all these TV shows I have that are around 700MB .avi files and they are taking anywhere from 400-600 minutes per file!!! That seems very long to me.
2. Do .VOB files typically take even longer to encode using H.264?
The few .VOB files I have tried are taking 800 or so minutes for a 2-3GB .vob file.
Is there something else I should be doing? Are these times normal?
Any tips or suggestions for encoding?
Thanks in advance.

Don't use VisualHub myself, but do know that h.264 encoding is extremely processor intensive and time consuming. The actual source material probably won't matter too much unless it's high definition or uses a particularly computationally intensive algorithm to decode (and for most decoding is miles faster than encoding).
For example, on my iMac (2.16GHz Intel core 2 duo) converting a 2-3GB '.rec' TV recording from a Topfield PVR (which in essence produces MPEG2 transport streams), via MPEG Streamclip can take 3-4 hours for say a 90-120 minute program, and that's without using 2 pass encoding.
VisualHub is regarded as one of the faster converters, but High Quality setting will take longer than 'Standard' and the 'Go nuts' option will take even longer.
Hopefully (though it may not be what you want to hear) someone with a G5 and VisualHub will reply to confirm the sort of encoding times you're experiencing - I say hopefully as if their times are much faster it points to some other factor than VisualHub.
Elgato make a hardware USB h.264 encoder which is supposed to speed up encoding considerably but it only accelerates specific applicatiosn (eg iMovie) or their own conversion application (so far - the latest MPEG Streamclip release suggests they will add an option to harness it if possible/feasible - it may not be).
There are mixed reports on the Elgato device - biggest gripes being lack of customisable settings and an 800x600 resolution maximum. I've got one on order - for some older stuff recorded off a PVR it'll probably be more than adequate but for newer things software encoding is likely to be better. Time vs quality trade off really.
Best h.264 encoding results for most at the present time will almost certainly be achieved in customisable converter software - there are probably professional high quality h264 hardware converters available but these would be prohibitively costly for most of us.

Adobe Dynamic Link Interlaced Question

I have several Dynamic Link files from After Effects in my Premiere Pro project - the final version of my project will be viewed on TV - so I want it to be interlaced. Are Dynamic Link files interlaced or should I export the files from After Effects into an interlaced format before exporting my project from Premiere Pro?
Thanks
FOO

Simple rule: anything that is created dynamically within AE (text layers, shape layers etc.) does not care - AE (and thus Dynamic Link) will correctly sample their properties at the given time, so fields are always correct based on your settings. For the rest - if your AE project uses footage, it needs to be interpreted correctly and the compas have the correct sizes. If so, you should have no problems using the stuff in Premiere and retaining the field order.

De-Interlace question

Hi everyone,
I'm working with some footage that was originally shot in HD, but brought into FCP as 720x486 anamorphic ProRes HQ. In the process, it seems some interlacing was introduced. I'm trying to make some quicktimes, and trying to de-interlace, but it seems either I have a relatively crisp picture that has all kinds of feathering going on in the places where there is movement, or if I apply the de-interlace filter and render out a QT, I the feathering goes away, but all of the edges appear jagged. I have looked at the field dominance on the imported media and applied the filter to that field, but it still looks bad. Can anyone help me figure out a better process?

Actually, I'd been under the impression that it was a deck downconvert upon import, but now I'm being told that it was not HD originally. Some of it was Digibeta, shot in 16:9, some of it DV cam (cloned to Digibeta) shot in 16:9. Uuuuggh. In any case, it's been really hard to get a clean, de-interlaced picture. Any advice would be most helpful.

De Interlace question for flicker???

I have frames that I made into freeze frames and they flicker. Also some slow motion that flickers
1. Which of the De-interlace settings solve this problem?
1a. is there a different setting for the freeze frame shot and the slow motion shot?
2. If I have a lot of shots can I select all and apply all at once?

If your clip flickers, try using the Filter: VIDEO- FLICKER FILTER as well as DE-INTERLACE.
For all slow motion shots (if shot on 29.97 FPS - NTSC) you should be using flicker removal and de-interlacing filters to smooth them out.
Create a nest and apply those filters at once on all your clips

H.264 encoding question

Let's say you have a typical Sony consumer camcorder that records video in H.264 and you produce a movie using a sequence created with the same settings as a native clip and encoded using same settings as sequence.
Then let's say later you want to encode that movie to another format, DVD or Vimeo or whatever. Is there a big difference between encoding from the aformentioned production file vs. the source clips? In other words - in this case - can that production file essentially act as a lossless compression format if created in this way?

While H.264 is more efficient than MPEG-2 for instance, providing decent quality at low bitrates, it is a lossy codec. Any time you re-encode your video, there is a quality loss. If possible, your best bet is to encode to various output formats direct from the Premiere sequence, using the original source material, so you are going from the camera clips direct to destination clips, with only one transcode taking place.
If you must create a "master clip" first that you will later create other files from, then you want that master to be a high-quality format. "Uncompressed" video takes up crazy amounts of space, so you'll want to find a codec that is considered "visually lossless", which will provide a high quality image with manageable size. Note these files are NOT for upload/web, they are too big, these are for keeping a master clip on your hard drive for archiving.
On the Mac, use Apple ProRes. On the PC, you can use the Avid DNxHD or Lagarith codecs, both available at no charge. You might also look at the Cineform codec. There's other options, but these are popular.

Boris continuum de-interlacer question dv 30fps to 24fps film conversion?

Just wondering what people think about converting NTSC interlaced dv video to film video at 24fps with a deinterlacer like the one that comes with boris continuum that does a simulation pulldown. Think I should just use a good deinterlacer or do you think I should convert my video to 24fps?
If everyone thinks I should do the pull down then I plan to use debug frameserver to encore and I will make a progressive dvd, does this sould like a good option.

And it will soon be getting even better… I am planning some updates for my dv2film functions: Better and faster deinterlacing, more accurate and faster motion compensation, multiprocessor optimization, so stay tuned!

RDe-interlace question

I'm relatively new to FCP but fairly knowledgable with regard to home theater. In discussions regarding de-interlacing it has been said that de-interlacing, at least in the context of editing in FCP, effectively throws away half the scan lines. It has been my understanding that de-interlacing reorders the scan lines in a sequential order (progressive). What am I missing?
Thanks

Quick Interlacing Question?

Hi,
I just rendered some progressive .m2v's out of AE for DVD Studio Pro.
The video for my menu I see in the properties it was 720X480i. I don't know why, so I switched it to
720X480p.
I then added some of my .m2v's to tracks in my project. When I clicked on the track I also saw it was 720X480i. I went to switch those to progressive, but the 720X480p was greyed out in the resolution option for the tracks?
Is this going to make my footage look any different on a television?
Thanks

It looks fine on the tv though so I guess 720X480i doesnt matter? Is this common?

Expectations for MPEG2 - H.264

I have some recorded television broadcasts on DVD (SD-PAL). On average 4.5 GB for 120 minutes per DVD, say about 5000 Kbps, if I am not mistaken. In the hope to reduce this appreciably by encoding in H.264 my question is: What sort of reduction/bitrate should I aim for in Compressor resulting in more or less the same quality in replay? I am aware of the fact that an exact answer cannot be given because of the dependence on the contents. But some rule of the thumb will be welcome.
Hans van der Meer

It will not make DV look better, it is a MPEG4 based compression format for material to be delivered over the web. As such, encoding your material to it it is the last step in the editing process.

Interlacing problem - display issue or something else?

Hi, another interlacing question...
So I captured my footage (originally shot on film, telecined to digibeta) at 10 bit uncompressed to do my online (the offline edit was a 29.97 DVCam dub of that digibeta). Since I'm finishing on 29.97 digibeta, I didn't remove the pulldown as I captured offline or online, and am editing both at my finishing medium's frame rate. So yes, I have the duped fields in there, but it also keeps things simple and I've theoretically been seeing exactly what the finished version will look like the whole time.
Last time I did this workflow I used a G4 running a dual 867 processor with a gig of RAM, and I had some jitter and interlacing "comb" visible when I watched the 10-bit on the Mac, but when I output to digibeta and DVD, it looked fine. So it appeared to be that my computer simply didn't have the juice to display it properly, but that the media itself was fine, as were both ways of outputting.
Now I have a spankin' new Mac Pro with a quad 2.66G processor and 3Gigs of RAM, so I figured that "display issue" was behind me. But not only do I still see jitter and comb on my computer monitor, I also see it much worse on the test DVD I just made. So the problem isn't just the display. The look is very similar to when you capture a clip and remove the pulldown, but fail to start capture on an A frame (but since this is all 29.97, I know that isn't the problem).
I thought it might be that the drives were not fast enough, so I reformatted two of my internal drives into a Raid 0 and put the media there and reconnected it. The raid seems happy, and it's less than half full, but the video doesn't look any better.
Any idea what else could be causing this? I did just upgrade the project from the FCP 4.5 version I started to the FCP 6 on the new machine, plus my experience has been that moving from offline DV to online can allow in some bugs, but the ins/outs, clip names, frame rates, haven't changed. And of course I've been editnig 29.97 DV this whole time without seeing any of the interlacing on the monitor or tyhe outputs. Could field dominance have anything to do with this? I've never adjusted that in previous applications of this workflow, so it doesn't seem relevant, but I confess I'm not sure what I'm messing with there. Do I need still more RAM? The computers we ran at school a couple of years ago were running 10 bit video on G5s without significant upgrades to my knowledge, and this is just a single stream with a few tracks of audio here. I'm afraid to spend any more $$ until I'm pretty confident it'll solve the problem (shoestring budget here of course). Any thoughts?
Many thanks.
-Jeremy

Thanks for the reply. I don't really have a way to hook up my computer to a broadcast monitor. I know I should, but can't really afford the card to do it. So I color corrected my footage carefully during telecine, and for things like this issue, I'm making DVDs quick and dirty through iDVD, then watching them on my home TV (an LCD that plays both SD and HD).
I suppose something in my DVD player and/or TV might be giving me the weirdness in the display, but I think I mentioned I did this same workflow before on a lowly G4, and back then while the computer display showed the interlacing problems, the final output looks fine on the same TV/DVD setup I'm using now. (And I also output that timeline on the previous project to a digibeta master and it looked great too--unfortunately no way to test that digibeta output on the present project without going to a post house, which of course cuts into the budget.)
Maybe I need to bite the bullet and stop being so cheap, but I'm hung up on the fact that it worked fine before, and I can't see how this stronger computer is performing comparatively poorly.
BTW I do see the interlacing in FCP viewer and canvas, but only when it's set to 100% size. And it looks identical in Quicktime as well.
The other thought that just occurred to me is that it might be a codec issue. Perhaps the uncompressed 10 bit codec on my new machine isn't quite the same 10 bit uncompressed as the Kona card used to capture the video for both new and old projects. Maybe my old computer worked ok because that codec was slightly different, or I may have even copied the codec to that computer at some point in the past.
Any of this spur any other ideas? Again I really appreciate the help...

Can I Encode to These Settings with Compressor??

Greetings,
I need some help from you good people.
I have been tasked with preparing our video program for an SD Television Broadcast.
In my many years of using Final Cut, I have never had to export for an official SD Broadcast. So I declare up front that this is a new world for me from web and DVD creation.
But I seem to be having a hard time matching all of these settings using an MPEG-2 Transport Stream in Compressor. So I want to know if I can use Compressor to match these settings or will I miss some of what the station wants?
I've tracked down most of the major settings in Compressor. I highlighted below in bold and red what I am having trouble with.
I will also add that I was trying to work with the GOP I and P frames settings but do not see a choice for selecting 1 frame for each one.
Most of my other issues are with the audio settings. I went to "Extras" and selected Multiplex but don't have any other control over the audio.
So any help would be much appreciated. Thanks!
These are the requirement sent from the station:
(BOLD AND RED are what I need help with)
VIDEO:
MPG TYPE: MPG-2
STREAM TYPE: PROGRAM (VIDEO + AUDIO)
VIDEO RESOLUTION: 720x480
FRAME RATE: 29.97 (NON-DROP) 4:3 DISPLAY
FIELD ENCODING: TOP FIELD FIRST
DEINTERLACING: USE TOP FIELD
BITRATE TYPE: VARIABLE (If they say a variable type, why would they state a Constant Bit Rate below??)
RATE CONTROL MODE: MODE 1
CBR BITRATE: 8000Kbps
GOP STRUCTURE:
I FRAMES: 1
P FRAMES: 1
PROFILE ID: 4:2:2
LEVEL ID: MAIN LEVEL
AUDIO: MPEG 1
AUDIO MODE: MPEG LAYER 2
AUDIO FREQUENCY: 48000 HZ STEREO
BITRATE: 256 KBPS* VARIABLE BITRATE EMBEDDED
MODE: STEREO
NO DE-EMPHASIS
MULTIPLEXING TYPE: MPG-2
Thanks in advance!

Disclosure: I haven't prepared a show for SD Broadcast either, but have been working with Compressor/DVDStudio Pro for a decade.
Looking at the specs, there are only a couple of unclear areas... the big thing is, they're asking for a Program Stream rather than Elementary Streams.
I looked into that codec and it seems capable of handling the task once you clear up the VBR/CBR and interlace/de-interlace questions.
Good luck!
