Hi,
I used this guide with succes to encode for Quicktime 7. Because I'm started from PAL video I used -fps 25 for the MP4box.exe command. The result is looking awesome in the quicktime and mpc players. Thanks for this great guide. However, my 60GB video Ipod is refusing to play it. Videos encoded using Quictime 7 Pro do work fine. Has anybody an idea how to change/adapt this guide for video on the iPod ? On the Apple pages, following information is stated:
H.264 video: up to 768 Kbps, 320 x 240, 30 frames per sec., Baseline Profile up to Level 1.3 with AAC-LC up to 160 Kbps, 48 Khz, stereo audio in .m4v, .mp4 and .mov file formats

The audio I've muxed in was compressed with Nero 7 (not the BeSweet procedure). and is MPEG-4 Main@L2 (AAC LC) at 96Kbps.

This is the info of the x264 generated video using MP4Box 0.4.0:

iPod and quicktime are different. donwload x264-psp from x264.nl and follow the instructions.

Randall · 20th November 2005, 23:51

hi cast42. Definately go with Sharktooth's recomendation, the x264-psp profile is excatly what you need for iPod compatible encoding. This guide was for QT compatibility, and iPod is a little different. For starters, the video size must be no bigger then 320 x 240 30 frames per sec. etc. And I believe that only the baseline profile will work with it. Also, my audio encoding profile won't work on iPod either. You'll need to use AAC LC encoding instead of the AAC HE. Finally, you must keep the bitrate down to 768 Kbps or lower. if you're doing ABR or VBR it's a good idea to keep it around 700 Kbps, because if I understand correctly, for iPod encoding you cannot be above 768 Kbps at any given moment.

smok3 · 21st November 2005, 12:09

framerate for ipod must be always 30fps?

No, that's just the maximum framerate that you can use. Sorry for the confusion.

cast42 · 22nd November 2005, 11:13

Hi,
Randall is right. 30fps is the maximum. Video generated from 25fps PAL play on Ipod:
Here an example of mp4info dump:

No success here. Still the same results, Quicktime plays the file but does not show picture. There is no sound track.

If some one wants to check this out, the stats files, the source and result are here: http://gandalf.lasipalatsi.net/testit/kimmotesti/

the command I am using is:

Code:

x264 --pass 1 --bitrate 839 --bframes 2 --subme 6 --analyse p8x8,b8x8,i4x4,p4x4 --me esa --progress --stats 1711.stats --no-psnr --output test-1711.mp4 klo5-6-f25-Ip.yuv 720x480

And this looks ok:

Code:

x264 [info]: using cpu capabilities MMX MMXEXT SSE SSE2 
mp4 [info]: initial delay 1 (scale 25)
x264 [info]: slice I:86    Avg QP:50.47  size: 12103

x264 [info]: kb/s:1744.6

encoded 320 frames, 1.06 fps, 1744.97 kb/s

Should I run the .mp4 thru mp4box even though I don't have sound?

smok3 · 23rd November 2005, 11:03

leban,
1. deleted, nm.
2. yes, you have to remux the file using mp4box.

here is my lil guide if it is of some use:

Those results do not look ok. 78% intra in P-frames? QP50 and still twice the requested bitrate?
Cause: your source is 640x480, not 720x480. And it's yuv4mpeg, not raw yuv.

Code:

mencoder -ovc copy -of rawvideo klo5-6-f25-Ip.y4m -o klo5-6-f25-Ip.yuv

You are rirght about that size. I tried it again with the right size. still nothing. How did you figure out that it is yuv4mpeg?

It is made with: jpeg2yuv -b 0 -f 25 -I p -j webcam_%07d.jpg

But that could be the cause for the persistent problem.

Randall · 29th November 2005, 16:57

Another thing, if you find that when you mux your audio and video with MP4Box QuickTime doesn't display the picture at all (no white box either) then try muxing again. I rarely run into this problem, but when I do, a second attempt at muxing solves it. Appears to be a completely random occurance.

GarfBond · 1st December 2005, 09:57

OK, I'm having some terrible luck with Quicktime and x264 all of a sudden. x264 380, QT7 pro, latest versions of megui and profiles, as well as mp4box.

Any advice would be greatly appreciated.

Randall · 1st December 2005, 15:12

You've been White Screen Of Deathed! WSOD sux0rs. Well, I would try it again without the

Code:

--b-rdo                 RD based mode decision for B-frames

QuickTime gets fussy about B frames. I don't believe you can have any more then 2 B-frames max. (QT Pro's own encoder only supports 1 B frame max, but I know that it's decoder can handle 2. May I suggest

Code:

"x264.exe" --pass 1 --bitrate 1208 --stats "H:\INC0NNS1\boundin.stats" --bframes 2 --subme 1  --analyse none --me esa --progress --no-psnr --output NUL "H:\INC0NNS1\boundin.avs" 

"x264.exe" --pass 2 --bitrate 1208 --stats "H:\INC0NNS1\boundin.stats" --bframes 2 --subme 6 --analyse p8x8,b8x8,i4x4,p4x4 --me esa --progress --no-psnr --output "H:\INC0NNS1\boundin.mp4" "H:\INC0NNS1\boundin.avs"

I know for a fact that QT works without --b-rdo and without --me dia. I'm not sure if either of those 2 settings are causing your WSOD problem, but those 2 settings jump out at me as a possible suspect. Try my command line and see what happens. Also, I have had trouble with the latest version of MP4Box, but it is not a White Screen Of Death problem, so I don't think MP4Box is your problem here, most likely it's your x264 settings. Try encoding to an actual mp4 container rather then a raw file. I have had more success this way.

Thanks for letting us know. Ok so I'm out of ideas as to why GarfBond's encode failed to render picture in QT then.
@GarfBond: Stick with Sharktooth's CE QuickTime profile and everything should be fine. It's in the sticky threads somewhere, and you need 7-zip to extract it.

Thanks for that profile Sharktooth.

Sharktooth · 1st December 2005, 20:26

maybe it's a matter of bitrate variance?
i really dont know. it works for some users and it doesnt for others...

That will kill your QT compatibility in a big way. Somebody could correct me here if I'm wrong, because I am not positive if --analyse all specifies everything like it would imply. I specified exactly the options that we wanted, just to avoid any possibility of that confusion.

--analyse all includes i8x8 if and only if --8x8dct is also specified. (It's not a question of profile; cqm will also set high profile, but won't enable i8x8.)

Randall · 1st December 2005, 23:12

Thanks for the info akupenguin. --analyse all == --analyse p8x8,b8x8,i4x4,p4x4
but typing

Code:

--analyse p8x8,b8x8,i4x4,p4x4

makes me feel good inside. That way I know exactly what the hell it is doing.

GarfBond · 2nd December 2005, 06:06

Part of my problem is that I've been using Sharktooth's CE-Quicktime profile

Today I just tried it outputting to .MP4 instead of a raw AVC file, but that was a no-go. Simply viewing the resulting MP4 file in QT results in no video at all (not even a white box of doom). After muxing it with the AAC file the video still isn't playing and the audio continues to work just fine.

Probably the most frustrating part is that everything plays in MPC just fine and dandy while QT sits there looking dumb. Anyone got any ideas?

Video generated from 25fps PAL play on Ipod: Here an example of mp4info dump: Track Type Info 1 audio MPEG-4 AAC LC, 47.693 secs, 128 kbps, 44100 Hz 2 video H264 Baseline@1.3, 48.360 secs, 579 kbps, 320x240 @ 25.000000 fp s To be more precise here an excerpt from an QT Pro generated .m4v with mp4dump: The majorbrand is M4V De video is: type avc1 reserved1 = <6 bytes> 00 00 00 00 00 00 dataReferenceIndex = 1 (0x0001) reserved2 = <16 bytes> 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 width = 320 (0x0140) height = 240 (0x00f0) reserved3 = <14 bytes> 00 48 00 00 00 48 00 00 00 00 00 00 00 01 compressorName = reserved4 = <4 bytes> 00 18 ff ff type avcC configurationVersion = 1 (0x01) AVCProfileIndication = 66 (0x42) profile_compatibility = 224 (0xe0) AVCLevelIndication = 13 (0x0d) reserved = 63 (0x3f) <6 bits> lengthSizeMinusOne = 3 (0x3) <2 bits> reserved1 = 7 (0x7) <3 bits> numOfSequenceParameterSets = 1 (0x01) <5 bits> <table entries suppressed> numOfPictureParameterSets = 1 (0x01) <table entries suppressed>

Definately go with Sharktooth's recomendation, the x264-psp profile is excatly what you need for iPod compatible encoding. This guide was for QT compatibility, and iPod is a little different. For starters, the video size must be no bigger then 320 x 240 30 frames per sec. etc. And I believe that only the baseline profile will work with it. Also, my audio encoding profile won't work on iPod either. You'll need to use AAC LC encoding instead of the AAC HE. Finally, you must keep the bitrate down to 768 Kbps or lower. if you're doing ABR or VBR it's a good idea to keep it around 700 Kbps, because if I understand correctly, for iPod encoding you cannot be above 768 Kbps at any given moment.

I rarely run into this problem, but when I do, a second attempt at muxing solves it. Appears to be a completely random occurance.

Randall Registered User Join Date: Sep 2005 Location: Norwood, MA Posts: 175	You've been White Screen Of Deathed! WSOD sux0rs. Well, I would try it again without the Code: --b-rdo RD based mode decision for B-frames QuickTime gets fussy about B frames. I don't believe you can have any more then 2 B-frames max. (QT Pro's own encoder only supports 1 B frame max, but I know that it's decoder can handle 2. May I suggest Code: "x264.exe" --pass 1 --bitrate 1208 --stats "H:\INC0NNS1\boundin.stats" --bframes 2 --subme 1 --analyse none --me esa --progress --no-psnr --output NUL "H:\INC0NNS1\boundin.avs" "x264.exe" --pass 2 --bitrate 1208 --stats "H:\INC0NNS1\boundin.stats" --bframes 2 --subme 6 --analyse p8x8,b8x8,i4x4,p4x4 --me esa --progress --no-psnr --output "H:\INC0NNS1\boundin.mp4" "H:\INC0NNS1\boundin.avs" I know for a fact that QT works without --b-rdo and without --me dia. I'm not sure if either of those 2 settings are causing your WSOD problem, but those 2 settings jump out at me as a possible suspect. Try my command line and see what happens. Also, I have had trouble with the latest version of MP4Box, but it is not a White Screen Of Death problem, so I don't think MP4Box is your problem here, most likely it's your x264 settings. Try encoding to an actual mp4 container rather then a raw file. I have had more success this way.

Randall Registered User Join Date: Sep 2005 Location: Norwood, MA Posts: 175	Thanks for the info akupenguin. --analyse all == --analyse p8x8,b8x8,i4x4,p4x4 but typing Code: --analyse p8x8,b8x8,i4x4,p4x4 makes me feel good inside. That way I know exactly what the hell it is doing.

GarfBond Registered User Join Date: Jan 2004 Posts: 11	Part of my problem is that I've been using Sharktooth's CE-Quicktime profile Today I just tried it outputting to .MP4 instead of a raw AVC file, but that was a no-go. Simply viewing the resulting MP4 file in QT results in no video at all (not even a white box of doom). After muxing it with the AAC file the video still isn't playing and the audio continues to work just fine. Probably the most frustrating part is that everything plays in MPC just fine and dandy while QT sits there looking dumb. Anyone got any ideas?
