Compressing HD PAL to mp4 before Jan1st

Trying to compress to death 2 very large files (11 and 12GB) to send via the Internet because there is no Fedex delivery on Jan1st. I'm using MPEG Streamclip. Going from HD PAL,1920x1080, 25fps, to mp4. I chose frame Size 720x576 but the image comes out squeezed and Streamclip has no Anamorphic optionto select. Is there another Frame Size you could recommend?
I tried exporting the file using Quick Time Conversion in FCP7 but the only option was "MPEG 4 Video" and it came out in slow motion!
Does anybody have a suggestion please? Many thanks

I didn't try compressor. I looked at Nick Holmes' Tutorial 2: it was about something else but he had a snapshot of Streamclip interface. I saw a Frame Size I don't have: 824x480 (16:9).
So I tried that ratio in mp4. It's OK but the file only went down from 11GB to 8GB. I'm looking to go down to about 2GB! Do you have any tip? Or we can continue this conversation later because another deadline just came up.
I'll talk to you in the New Year. Happy New Year!!!

Cannot edit MP4 files, maybe compression error?

Hi, I'm new to Final Cut Express. I just bought it to replace iMovie. But I'm having a issue - only had it open for not even a hour and I started getting a "General Error", specifically "Out of Memory". It was a mp4 clip, like this:
MPEG-4 MOVIE
1280x720
H.264, MPEG 4 HIGH EFFICIENCY AAC
2 (Audio Channels)
3,127 (Bit rate)
45.5 MB
I browsed the forums for a bit, trying to figure out what I could do to make the errors go away. I've never had problems with compression or anything like this before. I saw somewhere that I should use MPEG Streamclip to convert the clip to .mov using Apple Intermediate, but MPEG couldn't edit the file either, although it played it fine. I tried going in and trying to export to .mov via Quicktime, but it only exported a completely white video with normal audio. I have no idea what to do now.
Why is this happening, how do I fix or prevent it from happening??

I think you missed me a little here... from MPEG Streamclip, I took the original dimensions and tried to convert it to quicktime with the following settings:
APPLE INTERMEDIATE CODEC
QUALITY 100%
UNCOMPRESSED SOUND
1280x720 UNSCALED
FRAMERATE 29.97
When I try to convert like this, using any of the clips (the clip I had originally talked about was one out of a batch of twenty, I tested them all last night after posting a realized they all get the same error) I get a empty, 0kb file and a Error that says it can't prepare the movie.
FCE won't even open the video at all. I can import it, but when I try to open it with the viewer it doesn't open, it simply spits out a general memory error. It's my Quicktime that does the white screen every time I try and convert the movie through it.
I will however, try to change the setup of my FCE Sequence... when trying to use this clips I was using HDV-APPLE INTERMEDIATE CODEC 1080i50. I was using it because I need the 1080p (this is for Youtube) and it was the only easy setup that was the size I needed. I'm a noob, I don't have any idea on how to change the size of the video (just any easy setup gives me the old square video, so if I try to change it when rendering the clips would be all placed weird with possible gaps).

Compression for ftp transfer before re-editing footage in FCP

Hi to all,
I am soon going to be receiving DV footage daily,that is going to be sent via ftp transfer. I will then be editing that footage and posting it on the web.
The people sending the footage will have little internet access time during their trip.
Since the end result is for web purposes, i would like the shooters to compress their PAL footage in 320x240 before posting in on the ftp.
Would anyone have any suggestions as far as to what would be the most appropriate compression options out of FCP for it to be light enough to travel fast, and easily re-imported in FCP after arrival.
I would assume i would then calibrate my projet to the settings that have been sent, right?
thanks for your help.
Tee.

Thanks for your answers.
I'm aware of the terrible quality loss that will be occurring.
The end format is for the web, and the idea is to keep a chronicle of the 2 week event, with a short video update.
The subject matter is what is of importance here. The event is a 2 week demonstration across europe against unemployment and growing social injustice.
It would be great to have more time and money to use the original footage (via fedex and later editing).
But i will try diffrent transfer options. One may work.
My main question is, (with this totally random example)
lets say i receive a compressed sorenson 3 .mov at 320x240 frame size, with a keyframe at every 15i, sound converted to stereo AAC at 96 kbps....
When i import that file in final cut,can i adjust my presets to match that?
Or will i need to edit in a DVPAL 720x576 preset, and render...
thanks again;

Compressing PAL HD to MPEG4 turns "skinny" picture

I am trying to Compress a PAL HD 720x576, Compressor: H 264, Pixel Aspect: PAL - CCIR 601, Field dominance: Upper (Odd) to PAL Low Res (MPEG4).
I followed previous advice to use Geometry in Inspector: with .75 Pixel Aspect Ratio, specifying 16.9 dimension. And I end up with a skinny image.
How can I get a 16.9 aspect ratio please, at the same time as I'm compressing to Low Res? Thank you for your help.

Dear Nick, the advice of selecting Pixel Ratio .75 and Ratio 16.9 in Compressor > Inspector > Geometry > was given to me on the Forum. Would you know of a place (tutorial, paper...etc) which gives the different Ratios for 4.3 & 16.9 in NTSC and PAL? Where could I acquire that knowledge? I'd be most grateful for a direction. Many thanks.

SD DVD Compressions

I have been compressing for like the last six months with Compressor, Compressor 2 and Bit Vice and for the life of me can't get anything that holds up quality wise. The cow has been great in solving problems in the past and have helped to an extent but I have still not burned a DVD that holds up yet. So I figured I'd try this. I am not trying to become a compression master...I am happy just being an editor that understands compression. I'd just like to create a simplistic workflow that allows me to produce nice looking DVD's and not ones that don't look much better than VHS. So here is a common scenario for me. I would like to know the best workflow to create the HIGHEST quality MPEG2 that I can to playback on a DVD. I don't care about file size or length of the compression. I'll be indebted to anyone that can help me work this out.
Current workflow-HDV sequence with HDV captured 1440X1080 ftg mixed in with computer 3D graphics of Animation(1980X1020), Photo-JPEG(1920X1080) and HDV(1440X1080) codecs.
My other 2 most common sequences that my workflow begins in are Blackmagic NTSC-Jpeg(Photo-Jpeg) & DV NTSC. I don't know if you would recommend a different process for these 2 but if so then I would be indebted to know these answers as well. I would hope that the compression would be pretty much the same in these based on what quality level you want.
Here's an example of my how I go and still get bad results. I finish my FCP (HDV, Blackmagic NTSC-Jpeg and DV NTSC)Sequence and then export to Compressor 2. The only thing that ever changes is when I work in an HDV sequence it will not let me export directly from the sequence claiming that I have not selected any media. So I have to take the extra step of exporting as a quicktime movie reference file to bring into compressor 2. I will then select Best Quality 90 minute 4:3 or 16:9 depending on the aspect ratio I need. I then have been assuming that for the highest quality I have been selecting GOP-IP and I have tried both 2-PASS VBR and Constant Bit Rates of anywhere from 7.0 to 8.0 with not much difference in results. I have tried all the GOP settings as well.
FYI - I've have tried dumping out my HDV sequence out to the deck and bringing it back in as a DV clip. I would then compress the 720X480 DV clip without any better results. The best results that I have come to find in all of my testing is bumping the HDV sequence up to uncompressed 8-bit or animation, rendering and then going through compressor or bitvice. BitVice gives me a little better results but nothing to write home about. I'm not opposed to using BitVice but would prefer to stay within the Apple workflow and just export through Compressor unless BitVice is the answer.
I have researched all of the forums and sites to I'm about blue in the face and have tried various things that have helped from many of the members. So thanks to everyone that has helped me or someone else that I have been able to take there suggestion for myself. I am just looking to get over that last hump!
It is not like it is unviewable but that I would like for it to look as good as it does in the sequence in FCP or at least 80-90% close. Right now to us it looks like it takes such a hit that it is like 60% is good as it was in the FCP sequence and only like 10% better than vhs if that:( Is there some hidden secret that I am missing in software compression that could get me over that remaining hump or am I stuck viewing similiar quality to vhs?
Sorry for the long post. Thanks in advance for everything!

Hey Lee, looking at what you are doing and how you are doing, let me make some recommendations.
obviously you are able to capture an 8 and 10-bit uncompressed 4:2:2 YUV NTSC and PAL elements from your internal drive with no problems (since you mentioned Blackmagic's Decklinck card). but you said that you are working with HD material, so assume you have some faster external drives. anyway, bring in the material in the highest quality you can in the above choices the 10-bit would be ideal.
what are your source tapes? i ask this bcz if they are some form of DV format (HDCAM, HDCAM PRO) your material is already compressed 5:1 (not helpful).
ok, you say that your FCP sequences are "Blackmagic NTSC-Jpeg(Photo-Jpeg) & DV NTSC".. WHY? although the file sizes might be atractive, once again, you are implemnting a compression to those files (cascade compression). something in the ballpark of another 5:1 to 15:1.
when you export your sequence from FCP do it with NO compression or in the drop-down options box "compression type = NONE". yes the files will be MUCH larger, but your material will mostly still be in the realm of 5:1 rather than the 10:1 to 20:1 compression (starting to see, even BEFORE you start encoding your how much your RAW "uncompressed" material is compressed).
OK, now you have these HUGE files on your HDD, since you are working with HD and you want to ultimately have a SD DVD, you have do to a down-conversion of the material.
one of the options to do a donw-convert is compressor. (i wouldn't recoomend it though). i would highly recommend do the down-conversion within FCP so once you do your export, your files are in SD resolution already (more than likely DV NTSC 640x480).
anyway, let's say that you already have a SD resolution file, you take that file into compressor (most DVD compression introduces about 40:1 compression) and just select a preset (they are generally pretty good) and see what relults that gives you.
i see that you set your GOP to IP ? a big no no! i hate to feel like i am demeaning you but do you know what GOP means, does or how it works?
having a setting of IP not only gives you larger files, since more whole frame (I) are created, but there is nothing beneficial and the encoding process is SEVERLY hindered since the encoder is not being effectively used.
i would try a setting of a CLOSED GOP @ 15 with a setting of IBBP since this is the MOST effective use of encoding or bit-reduction.
i think i touched most subjects.. wow i am exhausted!
if you have any specific questions as to how or why, let me know and i will answer them as best as i can

No audio in MP4 file ?

I was export timeline xdcam 35 mbs, 720p 50 fps to MP4 720p 50 fps.
When looking video on Mac everything is ok, but, when I copy MP4 file to USB and put directly to LCD there is only video, no audio? Before on G5 I was use matrox compress card, and always MP4 file was ok on LCD. Where is problem? tnx.

I do not know maybe it's a coincidence. Because I was made before in the AAC audio format, so one video has audio on LCD, second NO, although there is same preset from Compresor. Before with Matrox Compress HD on G5 has never been a problem.
In this MP4 I haven't audio on LCD, AAC, 44.1 khz,
And Why is original height/widht not same like encoded video? I did not touch the video settings, such Crop

Help for Creating PAL DVD

I have NTSC footage that I edited on Final Cut Pro HD and now I need to create a PAL DVD. I did it before using the same footage, same Final Cut program, but that was a few months ago and I forgot what format I chose on Compressor to export (if it was Compressor) The only options I see on Compressor for PAL are MP4-which I thought was for the web.
Thanks!

Compressed videos not playing in IPAD

Hi,
I am using flash professional cs6 .my project is depends upon Multimedia.mainly my Application for iPad.
I am using some videos which are in .flv . Those flv files are too large so that i compressed all videos and loaded into my application.After building application those compressed videos are playing fine in my application.
But after published my application into .ipa file. and installed in IPad.but videos are not playing.
Please if any faced this problem suggest me.
I have done In My application with Videos
1.Compressed all videos into .MP4
2.Runed my application and tested ,Status: All videos are playing good
3.Published my App into .ipa
4..ipa file installed in IPAD, Status: Videos are not visible
Advance Thanks

Please post the codec details of your videos. MP4 is a container that supports a variety of audio and video codecs. Chances are you may have used a codec iPad doesn't support.
All my MP4s for iPad are using good old MainConcept H.264 for video and AAC stereo for audio. All playback is fine. Are you using something like x264 or something non-H.264?

I compressed Activity Monitor and deleted the compressed file in error. How do I get it back?

In trying to reduce my CPU load, I compressed the Activity Monitor. Before I can use the compressed file, I mistakenly deleted it and now when I try to open it, I get the dreaded spinning wheel. After a long wait, I forced quit.
What happened and how do I get Activity Monitor back?

Never tamper with programs which come with the system. You could try downloading and applying the 'combo updater':
http://support.apple.com/kb/DL1399
However this won't help if Activity Monitor hasn't been updated since the initial release, which may well be the case. In that event you will need to reinstall Snow Leopard from your original install disks and then apply the combo updater again.
Alternatively it may be possible to extract Activity Monitor from the installed disk by using Pacifist - no promises about that.

Always larger Swap memory than compressed in Mavericks 10.9.3

I bought MBP about 3 weeks ago and had an update to Mavericks 10.9.3 a few days ago.
I am not sure if this problem started after the update, but I had never seen any "Swap Used" at least before the update.
Now, if you look at the screenshot below, which is my current memory status, there is always a certain amount of Swap Used, and the amount is always larger / comparable to that of "Compressed" memory.
I have never seen that my memory pressure goes to yellow or red, and I am not a heavy user either.
Also, I have not felt any slow down of my mac yet.
To my understanding, Mavericks is made to compress as much as possible before it starts to swap the memory with hard disks. But it seems like mine does not work in that way for some reason now.
The link below provides an enlightening explanation on how Mavericks manages its RAM. In the test done in the article, you can notice that the Mavericks compresses more than 8 GB before it actually starts the swap process under a heavy load.
http://arstechnica.com/apple/2013/10/os-x-10-9/17/
So, what did happen to my Mavericks? Why is it using the swap before it compresses more, leading to more Swap Used than Compressed?
Any thoughts?
Thanks,

I would not be concerned about such tiny amounts of Ram

Flash file 1920x1080 (touchscreen) compressed to website version 945x532

Hi
We have create a flash file for both Touchscreen TV and Website.
The document frame is is 1920x1080 however we would like to export the project so it can be seen on the website at the correct compression.
Is there a way to export the SWF to the required 945x532.
I know how to export it in the HTML however this reads the same SWF that is still too large in file size (not web friendly).
I could pull the compression down to say 10% before exporting the SWF however there must be a better method.
Thanks
Craig

Thanks Iranten however my problem is not scaling the swf size as I can change that in dreamweaver or directly from flash by specifying the frame size.
I am trying to find out what the best method for scaling down the frame size and compression with in flash.
My current project is 1920x1080 and the images are all high resolution so they look good on the touchscreen.
I am wondering if you can reduce the frame size in flash and export the SWF file out compressed as a web version.
In short to avoid having to recreate the whole project in a smaller version for the web.
I hope this makes sense.. been working all day and my head is starting to spin out...

DV Pal 4.3 play back problem.

Hi Every One.
Hopefully you can help and put my mind at rest.
I have a music video to be submited to TV.
Out of Final Cut Pro X the video is crisp. When converted in i Movie to You Tube, the video is crisp.
1 of the channel's the video is being submited to require the file to be ... Compression: DV – PAL. Quality: Best. Frame Rate: 25. Scan Mode: Interlaced. Aspect Ratio: 4:3. Dimensions: 720x576 (768x576). Audio -6db ... When I convert the original file from Final Cut Pro X in Compressor 4 to the format the channel require, the video and sound remain crisp on my Mac, even though there has been a conversion from 3.5G to 800MB.
Now, the concern I have, when I play the video back in Quicktime on a PC, the image and sound detirate A LOT, unless I set the Quicktime player in prefrences to "Use High Quality Video Settings When Available", once again in this mode the video and sound remain as crisp as on the Mac.
Should I be concerned that through out all of the conversion processes the video remains, crisp, and sharp, except with the Quicktime issue on a PC as stated above?
Thank you for your time.
Regards
Jack.

Here you go mate, let me know your thoughts. I'm hoping its just a Quick Time settings issue on PC and wont effect playback on TV, as its remained crisp and sharp through out original file from Final Cut, You Tube Conversion and DV Pal 4.3 conversion on my Mac.
Thank you for such a quick reply!

HD to PAL

I have a FCP file that is 720 24p DVCPRO HD. I need to make a PAL DVD. I realize that HD is neither PAL nor NTSC, so you wouldn't need a standards conversion. But rather than sending it out for downconversion, can you just output it to PAL specs? Or could you just also output it in it's current state to compressor to make a PAL MPEG2? Also, if there are titles in there, I'm guessing they might fall off the title-safe area in PAL where they worked in NTSC. I would then want to work from a PAL QT file before going to MPEG2 to adjust the subs-- unless somebody has a better way. Do you?
Thanks,
Alex

I've been having similar problems, and it appears as if us in PAL world seem to get hit harder with this, leading me to think that the problem is in the Upper Field Dominance of HD being sloppily converted to Lower Field Dominance of PAL DVD. Those in NTSC world start in upper and finish in upper field dominance.
For the record, I'm using HDV 1080i 50 footage from our Z5's recording to flash card, ingested using Log and Transfer (with the Sony memory unit plug for FCP installed).
Many people have put forward their suggestions for HD to DVD workflow. Almost all of them are from the US and don't have to worry about moving from one format to another with different field dominance. No one has been able to tell me where the change takes place... they just know it happens somehow. If you are going from FCP to Compressor to DVD SP, I think DVD SP is changing the dominance as it preps for PAL DVD. I don't know how hard the conversion is, but I don't like the idea of DVD SP doing it.
I tried changing Compressor's settings to output in lower field dominance, btu all I got was unwatchable flicker.
I tried a demo version of BitVice and it yielded the same results as Compressor (just poor quality when field dominance set to "Same as source" and unwatchable flicker when set to lower). This adds weight to my theory that the problem is in the field dominance conversion which I think is being done by DVD SP. Maybe if an expert on this field dominance can confirm or rule out my theory, I can move past this bump in the road.
Has anyone tried moving projects over to the Adove suite and outputted via Encore?
Cheers
Dav

Is there any difference in quality between mp4 and m4v?

Is there any difference in quality between mp4 and m4v? I am figuring out how best to save old VCR files. Is the 264 category the best?

So, what would that software be? Anything that I mentioned, e.g., iMovie? Any Video Converter?
I'm a Mac user so I want files that play "natively" in QT X, QT 7, QL, iPod Touch, iPhone, iPad, and/or TV players. This means I want the H.264/AAC compressed data in MOV, MP4, or M4V file containers. I can use QT 7 Pro, MPEG Streamclip, and /or QT X to move MPEG-4/AAC compressed data to MOV file containers, MPEG Streamclip to movie M4V and MOV MPEG-4/AAC data to MP4 file containers, and Subler to move MP4 or MOV MPEG-4 AVC/AAC/AC3/Chapter data to M4V file containers. This is strictly a simple "copy" operation and no recompression of data is involved. (I.e., the quality is not changed.)
iMovie is a video editor and it forces an export conversion of your project once completed which can degrade quality. Have never used the Any Video Converter so I don't know if it has an audio and/or video "passthrough" feature for data already in a compatible compression formats. If it doesn't then any conversion it makes has the potential to degrade video content.
As to AVI, this is a legacy file container abandoned by Microsoft a dozen years ago in favor of their modernized WMV compression format/file type products. Compared to MKV, AVI is an outmoded/out-of-date container which I don't recommend you use unless you are a glutton for punishment. However, if you must use it, then you might try the AvidMux app. It can "copy" compatible content to a number of file container types—including AVI and MKV. Just don't blame me if its use creates more problems than it solves on current Mac systems.
